Description

  The present invention relates to a vehicular lamp using an annular light guide member.

  Some vehicular lamps used in vehicles include a lamp unit provided in a lamp chamber (see, for example, Patent Document 1). In such a vehicular lamp, it is conceivable to provide an annular light guide member so as to surround the lamp unit when viewed from the front in order to improve the appearance.

  Here, in the vehicular lamp, it may be required to reduce the overall size as viewed from the front. In this case, in the vehicular lamp configured as described above, it is necessary to reduce the inner diameter of the annular light guide member, but there is a limit to reducing the size of the lamp unit. For this reason, in the vehicular lamp, the lamp unit is not completely surrounded by the light guide member, but the lamp unit is surrounded by the light guide member while a part of the lamp unit is disposed on the light guide member. It is conceivable to reduce the light guide member (inner diameter dimension). In such a configuration, since the light guide member cannot overlap with the lamp unit, it is considered that the lamp unit is sandwiched between both ends formed by cutting out a part of the light guide member. . In the vehicular lamp configured as described above, the light guide member can be illuminated uniformly over the entire surface by providing a light source at each end of the light guide member. Thereby, in the vehicular lamp, the annular light guide member can be provided so as to surround the lamp unit while reducing the overall size when viewed from the front.

  Embodiments of a vehicular lamp according to the present invention will be described below with reference to the drawings.

  A vehicle lamp 10 of an embodiment as an example of a vehicle lamp according to the present invention will be described with reference to FIGS. 1 to 9. In FIG. 5, the annular lens 42 in the clearance lamp 17 is omitted and the illumination lamp unit 15 and the turn lamp unit 16 as the lamp unit are shown as simple circles in order to facilitate understanding of the positional relationship. Further, in FIG. 3, the light guide member 30 in the state provided in the lamp chamber 14 is indicated by a broken line in order to easily grasp the position of the light guide member 30 in the overall configuration. Further, FIG. 6 shows the light guide member 30 and the LED substrate 43 in a state provided in the lamp chamber 14 indicated by a broken line in FIG. 7 to 9, the annular lens 42 of the clearance lamp 17 is omitted, the outer lens 13 of the vehicular lamp 10, the illumination lamp unit 15, The unit 16, the light guide member 30 of the clearance lamp 17, and both light sources 41 are shown in a simplified manner.

  As shown in FIG. 1, the vehicular lamp 10 is mounted on a vehicle 50 as a headlamp for an automobile or the like in order to irradiate the front. The vehicular lamps 10 are provided on the left and right sides (10L, 10R) in pairs at the front end of the vehicle 50, and are configured to be symmetrical and substantially equal to each other. In the following, since the left and right vehicle lamps 10 are symmetrical and substantially equal to each other, only the vehicle lamp 10L provided on the left side will be described, and the right vehicle lamp 10R will be omitted. The configuration is described as a vehicular lamp 10. In the following description, the front-rear direction (see arrow FB in FIG. 3 and the like), the horizontal (left-right) direction (see arrow RL), and the vertical (up-down) direction (see arrow UD) viewed from the driver in the vehicle 50 to be attached are used. . Moreover, since both the vehicle lamps 10 are provided on both the left and right sides of the front end portion of the vehicle 50, in the description relating to the horizontal direction, the vehicle lamp 10 (the center position) is used as a reference, and the vehicle 50 is located at the center position side. Is the vehicle inner side Si viewed in the horizontal direction, and the outer side of the vehicle 50 is the vehicle outer side So viewed in the horizontal direction.

  In the vehicular lamp 10, as shown in FIGS. 2 and 3, the lamp housing 11 whose front end is opened, the inner panel 12 provided inside the lamp housing 11, and the outer lens 13 attached to the front end of the lamp housing 11 (FIG. 2), the lamp chamber 14 is formed. The lamp housing 11 constitutes a mounting location for a lamp unit (illumination lamp unit 15 and turn lamp unit 16), which will be described later, and houses a lighting drive device for controlling the lighting of the lamp unit. The inner panel 12 enhances the design of the vehicular lamp 10 by concealing the lamp unit and a part other than the illumination part (the LED board 43 described later) in the clearance lamp 17 described later, the above-described lighting driving device, and the like. The inner panel 12 can be further improved in design by performing silver vapor deposition, aluminum vapor deposition, coating, or the like. In this embodiment, silver vapor deposition is performed. The outer lens 13 covers the lamp unit 11 (the lamp chamber 14) housed in the lamp unit (illumination lamp unit 15, turn lamp unit 16) and the clearance lamp 17 while allowing light to be emitted. In the embodiment, it is substantially circular when viewed from the front side in the front-rear direction.

  In the vehicular lamp 10, an illumination lamp unit 15 and a turn lamp unit 16 as lamp units are provided in a lamp chamber 14, and a clearance lamp (vehicle width lamp) 17 is provided surrounding the lamp units. The illumination lamp unit 15 illuminates the front of the vehicle 50 to improve the visibility of the driver and the ease of recognizing the vehicle 50 from the outside. In this embodiment, the light distribution for travel (high beam) And the light distribution for passing (low beam) can be switched. As shown in FIG. 3, the illumination lamp unit 15 includes a frame 18, a projection lens 19 that covers the front opening of the frame 18, and a reflector 21 that covers the rear opening of the frame 18. The projection lens 19 has a circular shape when viewed from the front side in the front-rear direction, and is attached to the front opening of the frame 18. For this reason, the illumination lamp unit 15 has a circular appearance when viewed from the front side in the front-rear direction.

  The reflector 21 has a bowl shape (a shape in which the diameter is gradually increased from the right side to the left side in FIG. 3) having a reflecting surface formed of a free-form surface based on an ellipse on the inside, and a rear end portion 21a (FIG. 3). An insertion hole 21b is provided in a bowl-shaped bottom portion which is the right end of the bottom. A discharge lamp 22 as a light source is provided in a space formed by the reflector 21, the frame 18, and the projection lens 19. In this embodiment, a high-pressure metal vapor discharge lamp such as a metal halide lamp or a high-intensity discharge lamp (HID) is used as the discharge lamp 22. The discharge lamp 22 can be attached to the reflector 21 through the insertion hole 21b of the reflector 21, and an igniter 23 is connected thereto. The igniter 23 can be attached to the illumination lamp unit 15 so as to be electrically connected to the discharge lamp 22 attached to the reflector 21 through the insertion hole 21b of the reflector 21. The igniter 23 is connected to a lighting drive device, and lights the discharge lamp 22 under the control of the igniter 23.

  In the illumination lamp unit 15, a shade 25 is provided so as to be movable in the vertical direction by the shade driving mechanism 24. The shade drive mechanism 24 is configured by providing a movable shaft portion 24b that is movable in a vertical direction on a main body portion 24a that incorporates a solenoid. The shade driving mechanism 24 has a shade 25 attached to the upper end portion of the movable shaft portion 24b, and moves the shade 25 in the vertical direction by moving the movable shaft portion 24b in the vertical direction with respect to the main body portion 24a. The shade drive mechanism 24 moves the shade 25 upward to position an upper end edge 25a, which will be described later, in the vicinity of the second focal point of the reflector 21 (its reflection surface), and then moves it downward from the upper end edge 25a. The upper edge 25a is positioned below the vicinity of the second focus.

  The shade 25 is composed of a member that blocks light transmission, and has a plate shape extending in the vertical direction and the horizontal direction. The shade 25 has an upper end edge 25a extending in the horizontal direction, and a step (not shown) is provided at the center of the upper end edge 25a. When the shade 25 is moved upward by the shade driving mechanism 24, the shade 25 is disposed on the optical path from the reflector 21 (its reflection surface) to the projection lens 19. Then, among the light beams that can be emitted from the discharge lamp 22 and emitted from the projection lens 19, the shade 25 emits from the projection lens 19 a light beam that is positioned substantially in the upper half when viewed in a cross section orthogonal to the irradiation optical axis. To prevent that. At this time, the shade 25 is positioned in the vicinity of the second focal point of the reflector 21 (reflection surface) in the vicinity of the upper end edge 25a, thereby following the shape of the upper end edge 25a at the upper end of the light beam emitted from the projection lens 19. A bright and dark boundary line (called a cut-off line) is formed. As a result, in the illumination lamp unit 15, a cut-off line in which the shape of the upper edge 25a is clearly reflected is formed from the projection lens 19, and the light distribution for passing through (low beam) that irradiates the front while preventing dazzling in the oncoming lane. ) As a light distribution pattern is emitted.

  Further, when the shade 25 is moved downward by the shade driving mechanism 24, the shade 25 is retracted from the optical path from the reflector 21 (its reflection surface) to the projection lens 19. For this reason, the shade 25 does not block the light beam that can be emitted from the discharge lamp 22 and emitted from the projection lens 19. Thereby, in the illumination lamp unit 15, the light beam which forms the light distribution pattern as the light distribution (high beam) for driving | running | working which can ensure a driver | operator's visibility from the projection lens 19 is radiate | emitted.

  The illumination lamp unit 15 is provided attached to the inner panel 12 or the like so that the projection lens 19 can be seen from an opening for the illumination lamp unit 15 provided on the inner panel 12. The illumination lamp unit 15 can illuminate the front of the vehicle 50 while switching between the light distribution for passing (low beam) and the light distribution for traveling (high beam) according to the control of the lighting driving device. For this reason, in the illumination lamp unit 15 (vehicle lamp 10), the front side in the front-rear direction is the side from which light is emitted.

  The illumination lamp unit 15 illuminates the front of the vehicle 50 (the front side in the front-rear direction (the side from which light is emitted)) in order to improve the visibility of the driver and the ease of recognition of the vehicle 50 from the outside. Other configurations may be used as long as they are present, and the configuration is not limited to the configuration of the present embodiment. In particular, the illumination lamp unit 15 is preferably switchable between a light distribution for passing (low beam) and a light distribution for traveling (high beam). In that case, two lamps are provided to switch the lighting. However, other configurations may be used and the configuration is not limited to the configuration of the present embodiment.

  The turn lamp unit 16 is provided in the lamp chamber 14 on the lower side in the vertical direction of the illumination lamp unit 15, and has a positional relationship in which the center positions of the turn lamp unit 16 are on the same straight line extending in the vertical direction when viewed from the front side in the front-rear direction. The For example, the turn lamp unit 16 includes a light source 27 disposed in a reflector 26 having a spheroid or paraboloid, and an inner lens 28 attached to the front surface of the reflector 26. The inner lens 28 has a circular shape smaller than the projection lens 19 of the illumination lamp unit 15 when viewed from the front side in the front-rear direction, and the outer shape viewed from the front side in the front-rear direction of the turn lamp unit 16 is circular. The turn lamp unit 16 is attached to the inner panel 12 or the like so that the inner lens 28 can be seen through an opening for the turn lamp unit 16 provided in the inner panel 12. In the turn lamp unit 16, when the light source 27 is turned on (flashes), light from the light source 27 travels directly or through the reflector 26 (its reflecting surface) to the inner lens 28, and the light mainly passes through the inner lens 28. The light is emitted to the front side in the front-rear direction. For this reason, the turn lamp unit 16 has a direction indicator corresponding to a position provided in the vehicle 50 (in this embodiment, a left-side direction indicator) when the light source 27 blinks under the control of the lighting drive device. Function as. Therefore, in the turn lamp unit 16 (vehicle lamp 10), the front side in the front-rear direction is the side from which light is emitted.

  As shown in FIGS. 2 to 6, the clearance lamp 17 has an annular shape that extends along the peripheral edge of the outer lens 13 while surrounding each lamp unit provided in the vehicular lamp 10. The clearance lamp 17 includes a long light guide member 30 extending so as to surround each lamp unit, that is, the illumination lamp unit 15 and the turn lamp unit 16, and both end portions of the light guide member 30 (both incident end portions 31, 32 described later). ) And an annular lens 42 that covers the light guide member 30. Both the light sources 41 form a light source in the clearance lamp 17, and a self-luminous semiconductor type light emitting unit such as an LED or an organic EL (OLED) can be used. Both light sources 41 use LEDs in this embodiment. Both the light sources 41 are mounted and provided on an LED substrate 43 provided with a circuit for appropriately driving (turning on and off), a connector for supplying power, and the like. The LED substrate 43 is fixedly provided on the back surface of the inner panel 12 or the like with the light source 41 mounted, and the mounted light source 41 is appropriately turned on and off. In this embodiment, the LED substrate 43 is provided corresponding to each of the two light sources 41, that is, the end portions of the light guide member 30 (both incident end portions 31 and 32 to be described later). The thing of Si inside a vehicle is made into the 1st LED board 431, and the thing of vehicle outside So is made into the 2nd LED board 432. FIG. Further, when both the light sources 41 are individually shown, those mounted on the first LED substrate 431 are referred to as a first light source 411, and those mounted on the second LED substrate 432 are referred to as a second light source 412.

  The light guide member 30 has a long rod shape as a whole, rises from the first incident end 31, extends while curving along the peripheral edge of the outer lens 13 (see FIG. 2) of the vehicular lamp 10, 2 An annular shape (circular shape) that hangs down toward the incident end 32. For this reason, when viewed from the front side in the front-rear direction, the light guide member 30 forms a notch 33 (see FIG. 5) between the first incident end 31 and the second incident end 32, and is circular as a whole. The surrounding area 34 (refer to the portion with dots in FIG. 5) is surrounded. Then, when viewed from the front side in the front-rear direction, the light guide member 30 positions the entire illumination lamp unit 15 within the surrounding region 34, and positions the center position O while positioning a part of the turn lamp unit 16 in the notch 33. Most of the turn lamp unit 16 including the lamp is located in the surrounding area 34 (see FIG. 5). In this embodiment, the turn lamp unit 16 has a circular center position O as viewed from the front side in the front-rear direction, and is vertically above the straight line L (the center side of the light guide member 30). They are positioned (see FIG. 5).

  A rotation angle occupied by the notch 33 in the light guide member 30 (an angle at which the notch 33 is located in a circumferential direction Dr (see FIG. 5 and the like) described later) is a diameter of the light guide member 30 (enclosed region 34). It is determined by the size and the diameter of the turn lamp unit 16. In the present embodiment, the rotation angle occupied by the notch 33 is 65 degrees, and the light guide member exceeds 2/3 in the length of the peripheral edge of the outer lens 13 (see FIG. 2) viewed in the circumferential direction Dr described later. 30 is present. For this reason, the light guide member 30 surrounds the illumination lamp unit 15 and the turn lamp unit 16 as a whole. The light guide member 30 has the first incident end portion 31 positioned on the vehicle inner side Si and the second incident end portion 32 positioned on the vehicle outer side So, and both the incident end portions 31 and 32 positioned lower, It is provided on the inner panel 12. Below, let the elongate direction of the light guide member 30 surrounding and surrounding the illumination lamp unit 15 and the turn lamp unit 16 be the circumferential direction Dr (refer FIG. 5).

  The light guide member 30 is formed of a glass material or a resin material. As the resin material, polycarbonate (PC), methacrylic resin (PMMA), cyclic olefin polymer (PCO), or the like can be used. In this embodiment, acrylic resin is used. In the light guide member 30, the first light source 411 mounted on the first LED substrate 431 is opposed to the first incident end 31, and the second light source 412 mounted on the second LED substrate 432 is opposed to the second incident end 32. Provided. In the light guide member 30, the light emitted from the first light source 411 enters from the first incident end portion 31, and the light emitted from the second light source 412 enters from the second incident end portion 32.

  In this embodiment, the light guide member 30 has a first incident end portion 31 and a second incident end portion 32 connected by a bridge piece 35. The bridge piece 35 does not interfere with the incidence of the light from the first light source 411 to the first incident end 31 and the incidence of the light from the second light source 412 to the second incident end 32. The first incident end portion 31 and the second incident end portion 32 are provided to be bridged. The spanning piece portion 35 assists the positioning and attachment of the light guide member 30 to the inner panel 12 and makes the light guide member 30 easy to handle by making it a continuous ring.

  In this embodiment, the light guide member 30 has a first incident end portion 31 and a second incident end portion 32 that are curved rearward in the front-rear direction, and can be positioned on the back side of the inner panel 12. (Refer to FIG. 2 etc.). In the light guide member 30, the light incident from the incident end portions 31 and 32 is advanced in the circumferential direction Dr (see FIG. 5 and the like) by using total reflection. In the light guide member 30, by forming a plurality of reflecting surfaces as total reflection prisms on the rear side in the front-rear direction, or by forming aluminum or silver on the back surface by vapor deposition or painting, etc., the plurality of reflecting surfaces are formed. A prism portion having a wave shape when viewed in a cross section along the circumferential direction Dr is provided. For this reason, in the light guide member 30, the light that is incident from the incident end portions 31 and 32 and travels in the circumferential direction Dr is emitted from the curved emission surface on the front side in the front-rear direction by the action of the prism portion. The light can be emitted to the front side in the direction and can be visually recognized from the up-down direction and the left-right direction on the front side. Therefore, in the light guide member 30 (clearance lamp 17 (vehicle lamp 10)), the front side in the front-rear direction is the side from which light is emitted.

  In the light guide member 30, the attachment portions 36 are provided at four locations at intervals from each other when viewed in the circumferential direction Dr (long direction). Each mounting portion 36 protrudes rearward in the front-rear direction from a flange portion protruding outward in the light guide member 30, and each has a shape corresponding to a mounted portion (not shown) provided on the inner panel 12. It is said. For this reason, the light guide member 30 is positioned and attached to the inner panel 12 by being arranged at a predetermined position of the inner panel 12 and inserting each attachment portion 36 into a corresponding attachment portion of the inner panel 12 ( 2 and 3). In this state, in the light guide member 30, the first incident end portion 31 and the second incident end portion 32 that are curved toward the rear side in the front-rear direction are positioned on the back side of the inner panel 12 (see FIG. 3). Then, on the back side of the inner panel 12, the first light source 411 is provided facing the first incident end portion 31, and the second light source 412 is provided facing the second incident end portion 32.

  The first LED substrate 431 on which the first light source 411 is mounted and the second LED substrate 432 on which the second light source 412 is mounted are positioned on the back side of the inner panel 12 (see FIG. 3). Both the LED substrates 43 (431, 432) have a plate shape along a plane orthogonal to the front-rear direction. Here, as described above, the turn lamp unit 16 is attached to the inner panel 12 or the like so that the inner lens 28 can be seen through the opening for the turn lamp unit 16 provided in the inner panel 12. Therefore, in the turn lamp unit 16, the reflector 26, the light source 27, and the like are positioned on the back side of the inner panel 12 (see FIG. 3). In the clearance lamp 17, the turn lamp unit 16 is positioned in the notch 33 of the light guide member 30, that is, the turn lamp unit 16 (part thereof) is formed by the first incident end 31 and the second incident end 32. The light guide member 30 is provided so as to be sandwiched. Therefore, the first LED substrate 431 on which the first light source 411 facing the first incident end 31 is mounted and the second LED substrate 432 on which the second light source 412 facing the second incident end 32 is mounted are front and rear. When viewed in the direction, the positional relationship overlaps with the turn lamp unit 16 (the reflector 26, the light source 27, etc.) (see FIG. 3). Therefore, both LED boards 43 (431, 432) may interfere with the turn lamp unit 16 (the reflector 26, the light source 27, etc.). For this reason, in the vehicle lamp 10, the two LED boards 43 (431, 432) in the clearance lamp 17 are arranged so as to have a positional relationship that does not interfere with the adjacent turn lamp unit 16.

  Among them, the first LED substrate 431 includes a portion where the first light source 411 is mounted (LED mounting portion) and a lighting circuit (lighting circuit) for turning on and off the first light source 411 and the second light source 412 in this embodiment. Part). The first LED board 431 extends from the position where the first light source 411 is provided, that is, the position facing the first incident end 31 to the lower side in the vertical direction. 2 side 412 side). Therefore, the first LED board 431 extends downward from the left side of the turn lamp unit 16 located in the notch 33 of the light guide member 30 when viewed from the front side in the front-rear direction, and from below the lower part of the turn lamp unit 16. It exhibits a generally L-shape that extends toward the side (see FIG. 5).

  Moreover, the 2nd LED board 432 comprises the location (LED mounting part) in which the 2nd light source 412 is mounted in a present Example. The second LED substrate 432 has a rectangular shape including a position where the second light source 412 is provided, that is, a position facing the second incident end 32. For this reason, the 2nd LED board 432 is located in the right side of the turn lamp unit 16 located in the notch part 33 of the light guide member 30 seeing from the front side in the front-back direction (refer FIG. 5). The second LED substrate 432 is connected to the first LED substrate 431 by a connection line. This is because the second LED substrate 432 constitutes a portion (LED mounting portion) where the second light source 412 is mounted, and a lighting circuit (lighting circuit portion) for turning on and off the second light source 412 is provided. This is because the first LED substrate 431 is provided. This connection line is located in the installation area | region 44 (refer FIG. 5) mentioned later with the 1st LED board 431 and the 2nd LED board 432. FIG.

  The vehicular lamp 10 has such a configuration that the LED boards 43 (431 and 432) in the clearance lamp 17 do not interfere with the turn lamp unit 16. In the clearance lamp 17, an annular lens 42 is provided so as to cover the light guide member 30 attached to the inner panel 12.

  As shown in FIGS. 2 and 3, the annular lens 42 has a substantially C shape that covers the light guide member 30 when viewed in a direction orthogonal to the circumferential direction Dr (see FIG. 3), and is viewed from the front side in the front-rear direction. And presents an annular shape extending along the light guide member 30 (see FIG. 2). The annular lens 42 is formed of a material that allows light to pass therethrough, and allows the light emitted from the light guide member 30 to illuminate the front side in the front-rear direction and the like, and the light guide member 30 is directly visually recognized. To prevent that. The annular lens 42 is positioned and attached to the inner panel 12 so as to cover the light guide member 30 attached to the inner panel 12.

  In this light guide member 30, when both light sources 41 (411, 412) mounted on both LED substrates 43 (431, 432) are turned on, light enters inward from both incident end portions 31, 32, Each light travels in the circumferential direction Dr. The light traveling through the light guide member 30 is emitted to the front side in the front-rear direction by being partially reflected by the prism portion as it travels. For this reason, the light guide member 30 has substantially uniform brightness over the entire length by turning on the light sources 41 (411, 412) under the control of a lighting circuit (lighting circuit unit) provided on the first LED substrate 431. It is possible to see from the up and down direction and the left and right direction on the front side. As a result, the clearance lamp 17 shines so as to surround the illumination lamp unit 15 and the turn lamp unit 16 along the peripheral edge of the outer lens 13, and a vehicle width lamp corresponding to the position provided in the vehicle 50 (this embodiment). In the example, it functions as the front left side width light).

  Thus, in the vehicular lamp 10, as shown in FIG. 2, the outer shape viewed from the front side in the front-rear direction is formed into a circular shape by the outer lens 13 having a substantially circular shape, and the outer lens 13 extends along the peripheral edge portion. An annular clearance lamp 17 (light guide member 30) extending in a circular shape forms a circular surrounding region 34. In the vehicular lamp 10, the illumination lamp unit 15 and the turn lamp unit 16 as lamp units surrounded by the clearance lamp 17 (light guide member 30) have a circular appearance when viewed from the front side in the front-rear direction. Yes. Therefore, in the vehicular lamp 10, when viewed from the front side in the front-rear direction, the circular outer lens 13 is edged by the annular (circular) clearance lamp 17, and the circular illumination lamp is inward of the clearance lamp 17. The unit 15 and the turn lamp unit 16 are designed to be located. In the vehicular lamp 10, a part of the turn lamp unit 16 is positioned in the notch 33 of the light guide member 30 of the clearance lamp 17, and the first incident end 31 and the second incident of the light guide member 30. The end lamp 32 and the end lamp 32 sandwich the turn lamp unit 16. For this reason, in the vehicular lamp 10, the clearance lamp 17 is positioned over 2/3 or more of the overall shape, that is, the length dimension of the outer peripheral portion of the outer lens 13 viewed in the circumferential direction Dr. The clearance lamp 17 is the illumination lamp unit 15 The turn lamp unit 16 is surrounded as a whole.

  Here, the vehicular lamp 10 has a design in which the circular illumination lamp unit 15 and the turn lamp unit 16 as the lamp unit are completely accommodated in the clearance lamp 17 (the light guide member 30 (the surrounding area 34)). It is possible. Then, in the vehicular lamp 10, it is necessary to increase the inner diameter dimension of the light guide member 30 (enclosed region 34), and the appearance shape (the outer lens 13 in this embodiment) and the overall size as viewed from the front side in the front-rear direction. The dimension increases. On the other hand, in the vehicular lamp 10, it may be required to make the appearance shape viewed from the front side in the front-rear direction as small as possible. In this case, in the vehicular lamp 10, it is necessary to reduce the inner diameter of the light guide member 30 (enclosed region 34), but the lamp unit (illumination) in which the light guide member 30 (enclosed region 34) is located inside. There is a risk of interference with the lamp unit 15 or the turn lamp unit 16). This is because there is a limit to reducing the size of the lamp unit (the illumination lamp unit 15 or the turn lamp unit 16). Therefore, in the vehicular lamp 10, the light guide member 30 is provided with the notch 33, and a part of the turn lamp unit 16 as one of the lamp units is provided in the notch 33, so that both the lamp units are connected to the clearance lamp 17. It can be considered to be a design that surrounds as a whole. At this time, since the light guide member 30 is provided along the peripheral edge of the outer lens 13 in the vehicular lamp 10, the notch 33 of the light guide member 30 and the lamp unit (turn lamp unit 16) provided therein are provided. It is desirable to make the distance to the smallest possible.

  Here, the two LED boards 43 (431, 432) in the clearance lamp 17 are likely to be thermally deteriorated or damaged when heated, and therefore it is required to be provided as far as possible from the heat source. In the vehicular lamp 10 of the present embodiment, the illumination lamp unit 15 and the turn lamp unit 16 used as the lamp unit are heat sources. The illumination lamp unit 15 illuminates the front of the vehicle 50 to improve the visibility of the driver and the ease of recognizing the vehicle 50 from the outside. Therefore, the illumination lamp unit 15 is continuously lit for a long time. Because there are many scenes and the required brightness is large, it generates a lot of heat. On the other hand, the turn lamp unit 16 blinks when notifying the direction of the direction when changing the course or when notifying the surroundings that the state is in an emergency state. Since there are many scenes and the required brightness is small, the heat generated compared with the lighting lamp unit 15 is small. In addition, the illuminating lamp unit 15 has an external shape that is larger than that of the turn lamp unit 16 when viewed from the front side in the front-rear direction.

  For these reasons, in the vehicular lamp 10 of the present embodiment, the turn lamp unit 16 that generates a small amount of heat and has a small external shape is provided on the lower side in the vertical direction, and a part of the turn lamp unit 16 is provided. Is configured to be sandwiched between the light guide members 30 (clearance lamps 17). Thereby, in the vehicle lamp 10, both the light sources 41 (411, 412) for the light guide member 30 can be brought close to the lamp unit (turn lamp unit 16), and the interval between the notches 33 in the light guide member 30, That is, the rotation angle occupied by the notch 33 in the light guide member 30 can be reduced. In the vehicular lamp 10, as shown in FIG. 5, the installation region 44 for installing both LED boards 43 (431, 432) is seen in the notch 33 of the light guide member 30 when viewed from the front side in the front-rear direction. The lamp unit (turn lamp unit 16) is formed in a U shape that connects both sides in the horizontal direction and the lower side in the vertical direction. That is, in the vehicular lamp 10, the installation area 44 is an area excluding the upper side in the vertical direction with respect to the lamp unit (turn lamp unit 16) located in the notch 33 of the light guide member 30 when viewed from the front side in the front-rear direction. Set to.

  In the vehicular lamp 10 according to the present embodiment, the two LED substrates, the first LED substrate 431 on which the first light source 411 is mounted and the second LED substrate 432 on which the second light source 412 is mounted, are arranged in the installation region 44. doing. Specifically, in the vehicular lamp 10, when viewed from the front side in the front-rear direction, the first LED substrate 431 extends from the left side of the turn lamp unit 16 downward and extends from the lower part to the lower side of the turn lamp unit 16. The second LED substrate 432 has a rectangular shape located on the right side of the turn lamp unit 16. As a result, in the vehicular lamp 10, both the LED boards 43 (431, 432) and the light guide member 30 (clearance lamp 17) and the LED lamps 43 (431, 432) and The influence of heat from the lamp units (illumination lamp unit 15 and turn lamp unit 16) of both light sources 41 (411, 412) mounted thereon can be reduced (almost eliminated). This is due to the following.

  First, for this description, the vehicle lamp (10A, 10B, as an example) in which the turn lamp unit 16 and the installation area (44A, 44B, 44C) are set in a different positional relationship from the vehicle lamp 10 of the present embodiment. 10C) is shown in FIGS. 7 to 9 show installation areas (44A, 44B, 44C) in which the LED boards are arranged instead of the LED boards in order to facilitate understanding of the positional relationships. Each of the installation areas (44A, 44B, 44C) includes both light sources 41 when viewed from the front side in the front-rear direction, because the LED substrate mounts both light sources 41 (411, 412). 41 (411, 412) necessarily includes the first incident end 31 and the second incident end 32 opposed to each other. In the vehicular lamps (10A, 10B, and 10C) shown in FIGS. 7 to 9, the basic concept and configuration are the same as those of the vehicular lamp 10 described above. A detailed description thereof will be omitted. In the vehicular lamps (10A, 10B, 10C), similarly to the vehicular lamp 10, a part of the turn lamp unit 16 is assumed to be positioned in the notch 33 of the clearance lamp 17 (light guide member 30). Yes.

  First, in the vehicular lamp 10A shown in FIG. 7, the illumination lamp unit 15 and the turn lamp unit 16 as the lamp unit are arranged in the horizontal direction, and the installation area 44A is horizontal with both sides of the turn lamp unit 16 viewed in the vertical direction. It is U-shaped that connects the right side seen in the direction in a band shape. That is, in this vehicle lamp 10A, the internal configuration of the vehicle lamp 10 is rotated 45 degrees counterclockwise when viewed from the front side in the front-rear direction. In the vehicular lamp 10 </ b> A, a part of the installation area 44 </ b> A, that is, the second light source 412 and the location where the second light source 412 is mounted on the LED substrate are located above the turn lamp unit 16 in the vertical direction. For this reason, there is a possibility that the second light source 412 or the LED substrate provided at the position in the installation region 44A may be thermally deteriorated or damaged due to the influence of heat generated from the turn lamp unit 16.

  Next, in the vehicular lamp 10B shown in FIG. 8, the illumination lamp unit 15 and the turn lamp unit 16 as the lamp unit are arranged in the horizontal direction, and both the installation areas 44B are viewed in the vertical direction of the turn lamp unit 16. It is U-shaped that connects the left side seen in the horizontal direction in a band shape. That is, in this vehicular lamp 10B, the location located on the right side of the turn lamp unit 16 in the installation area 44A of the vehicular lamp 10A shown in FIG. 7 is positioned between the illumination lamp unit 15 and the turn lamp unit 16. The installation area 44B is used. In the vehicular lamp 10B, as in the vehicular lamp 10A, a part of the installation region 44B, that is, the portion where the second light source 412 is mounted on the LED light source 412 and the LED substrate is on the upper side in the vertical direction of the turn lamp unit 16. To position. For this reason, there is a possibility that the second light source 412 or the LED substrate provided at the position in the installation region 44B may be thermally deteriorated or damaged due to the influence of heat emitted from the turn lamp unit 16. Further, in the vehicular lamp 10 </ b> B, a part of the installation area 44 </ b> B is located between the illumination lamp unit 15 and the turn lamp unit 16 and is close to the illumination lamp unit 15. For this reason, there is a possibility that the LED board provided at the position in the installation area 44B is affected by the heat generated from the illumination lamp unit 15 and is thermally deteriorated or damaged. In addition, in the vehicular lamp 10B, when an LED board is disposed between the illumination lamp unit 15 and the turn lamp unit 16 in the installation area 44B, the LED board interferes with the illumination lamp unit 15 and the turn lamp unit 16. There is a fear. For this reason, in the vehicular lamp 10B, it is necessary to widen the space between the illumination lamp unit 15 and the turn lamp unit 16 to at least ensure a space for arranging the LED boards. The shape will be increased.

  Next, in the vehicular lamp 10C shown in FIG. 9, the turn lamp unit 16 as the lamp unit is arranged on the lower side in the vertical direction of the illumination lamp unit 15 as the lamp unit, and the installation area 44C is arranged in the horizontal direction of the turn lamp unit 16. It is made into the U-shape which connects the both sides seen by and the upper side seen in the perpendicular direction in the shape of a belt. That is, in this vehicular lamp 10C, when viewed from the front side in the front-rear direction, a position located below the turn lamp unit 16 in the installation area 44 of the vehicular lamp 10 is located between the illumination lamp unit 15 and the turn lamp unit 16. It is set as the installation area 44C. In the vehicular lamp 10C, a part of the installation area 44C is located between the illumination lamp unit 15 and the turn lamp unit 16 and is close to the illumination lamp unit 15, and above the turn lamp unit 16 in the vertical direction. To position. For this reason, the LED substrate provided at the position in the installation area 44C is subject to thermal deterioration or damage due to the influence of heat emitted from the illumination lamp unit 15 and the influence of heat emitted from the turn lamp unit 16. May occur. In addition, in the vehicular lamp 10C, similarly to the vehicular lamp 10B, when an LED board is disposed between the illumination lamp unit 15 and the turn lamp unit 16, the LED board is connected to the illumination lamp unit 15 and the turn lamp unit 16. Since there is a possibility of interference, it is necessary to widen the distance between them, which leads to an increase in the external shape as viewed from the front side in the front-rear direction.

  On the other hand, in the vehicular lamp 10, as shown in FIG. 5, the lighting lamp unit 15 and the turn lamp unit 16 are arranged side by side in the vertical direction with the turn lamp unit 16 on the lower side in the vertical direction. In the vehicular lamp 10, when viewed from the front side in the front-rear direction, the turn lamp unit 16 as a lamp unit is provided in the notch 33 of the light guide member 30, and the installation region 44 is arranged in the horizontal direction with respect to the turn lamp unit 16. It is made into the U shape which connects the both sides of this and the vertical direction lower side in strip shape. For this reason, in the vehicular lamp 10, there is no place located on the upper side in the vertical direction of the turn lamp unit 16 in the installation area 44, and there is no place located between the illumination lamp unit 15 and the turn lamp unit 16. There is no part approaching the unit 15. As a result, in the vehicular lamp 10, even if the LED board 43 (431, 432) and the two light sources 41 (411, 412) are installed at any location in the installation area 44, the illumination lamp unit 15 and the turn lamp It is possible to prevent thermal degradation or damage from occurring due to the influence of heat generated from the unit 16.

  Thus, in the vehicular lamp 10 according to the embodiment of the vehicular lamp according to the present invention, the installation unit 44 is viewed from the front side in the front-rear direction, and is sandwiched between the incident end portions 31 and 32 (in the embodiment, the turn unit is turned). The lamp unit 16) is set on both sides in the horizontal direction and on the lower side in the vertical direction. For this reason, in the vehicular lamp 10, even when both the light sources 41 and the LED substrate 43 are installed in any part of the installation area 44, thermal deterioration or damage occurs due to the influence of heat generated from the lamp unit. Can be prevented.

  Further, in the vehicular lamp 10, the installation area 44 is set on both sides in the horizontal direction and on the lower side in the vertical direction with respect to the lamp unit (turn lamp unit 16) sandwiched between the incident end portions 31 and 32. The deterioration and damage of both the light sources 41 and the LED substrate 43 due to the heat from the lamp unit are prevented. For this reason, in the vehicular lamp 10, both the light sources 41 (411, 412) can be provided at a position sandwiching the lamp unit. Therefore, the notch 33 is provided in the light guide member 30 and one of the lamp units is provided in the notch 33. Can be provided. Thereby, in the vehicular lamp 10, the inner diameter dimension of the light guide member 30 surrounding the lamp unit can be reduced, and the external shape seen from the front side in the front-rear direction can be reduced. In addition, in the vehicular lamp 10, both light sources 41 (411, 412) can be disposed close to the lamp unit, and both incident ends at which the light sources 41 (411, 412) are opposed to each other in the light guide member 30. The parts 31 and 32 can be brought close to the lamp unit. Moreover, in the vehicular lamp 10, the light source 41 (411, 412) can be provided so as to face each of the incident end portions 31, 32 sandwiching the lamp unit, so that the light guide member 30 is bright and covers the entire length. It can be made to emit light substantially uniformly.

  Further, in the vehicular lamp 10, a lamp unit (turn lamp unit 16) on the lower side in the vertical direction of two lamp units (illumination lamp unit 15 and turn lamp unit 16) provided in the lamp chamber 14 in the vertical direction. A light guide member 30 (clearance lamp 17) is provided by sandwiching a part of the light guide between the incident end portions 31 and 32. For this reason, in the vehicle lamp 10, both the light sources 41 (411, 412) and the LED substrate 43 provided in the installation area 44 are positioned between the two lamp units or on the upper side in the vertical direction of one of the lamp units. There is no. As a result, the vehicular lamp 10 guides the two lamp units while preventing both the light sources 41 and the LED substrate 43 from being thermally deteriorated or damaged due to the influence of heat generated from each lamp unit. It can be surrounded by the member 30.

  In the vehicular lamp 10, the two lamp units surrounded by the light guide member 30 (clearance lamp 17) have a circular shape when viewed from the light emission side. For this reason, in the vehicular lamp 10, when viewed from the front side in the front-rear direction, two circular lamp units can be located inside the light guide member 30 (clearance lamp 17) that has an annular shape (circular shape). The appearance can be improved.

  In the vehicular lamp 10, when viewed from the front side in the front-rear direction, the lamp unit on the lower side in the vertical direction of the two lamp units (illumination lamp unit 15 and turn lamp unit 16) provided in the lamp chamber 14 in the vertical direction ( A circular center position O in the turn lamp unit 16) is located in a circular surrounding region 34 drawn by the annular light guide member 30. For this reason, in the vehicular lamp 10, the two lamp units arranged in the vertical direction can be more appropriately surrounded by the light guide member 30, and the lamp unit on the lower side in the vertical direction in the light guide member 30 (the surrounding area 34). It is possible to reduce the rotation angle occupied by the notch 33 for providing the. In particular, in the vehicular lamp 10, when viewed from the front side in the front-rear direction, the circular center position O of the lamp unit (turn lamp unit 16) on the lower side in the vertical direction is defined by a straight line L that spans the light sources 41 (411, 412). Is also positioned on the upper side in the vertical direction. For this reason, in the vehicular lamp 10, the two lamp units arranged in the vertical direction can be more appropriately surrounded by the light guide member 30, and the lamp unit on the lower side in the vertical direction in the light guide member 30 (the surrounding area 34). The angle of rotation occupied by the notch 33 for providing the can be made smaller. Thereby, in the vehicular lamp 10, the appearance shape seen from the front side in the front-rear direction can be further reduced, and the appearance can be further improved.

  In the vehicular lamp 10, when viewed from the front side in the front-rear direction, the inner diameter dimension of the lamp unit (turn lamp unit 16) on the lower side in the vertical direction of the two lamp units provided in the lamp chamber 14 in the vertical direction is set to be vertical. It is made smaller than the inner diameter dimension of the lamp unit (illumination lamp unit 15) on the upper side in the direction. For this reason, in the vehicle lamp 10, the rotation angle occupied by the notch 33 for providing the lamp unit on the lower side in the vertical direction in the light guide member 30 (the surrounding area 34) can be further reduced.

  In the vehicular lamp 10, an illumination lamp unit 15 and a turn lamp unit 16 are provided from the upper side in the lamp chamber 14 in the vertical direction, and a part of the turn lamp unit 16 on the lower side in the vertical direction is connected to both incident end portions 31, The light guide member 30 (clearance lamp 17) is provided between 32. For this reason, in the vehicular lamp 10, since the turn lamp unit 16 generates less heat than the illumination lamp unit 15, both the light sources 41 (411, 412) provided facing both the incident end portions 31 and 32 and those are mounted. The LED substrate 43 to be arranged can be disposed in the vicinity of the turn lamp unit 16.

  In the vehicular lamp 10, as viewed from the front side in the front-rear direction, a light guide member 30 surrounding the lamp unit (the illumination lamp unit 15 and the turn lamp unit 16) is provided in an annular shape extending along the peripheral edge of the circular outer lens 13. ing. For this reason, in the vehicle lamp 10, the outer lens 13 can be bordered with the light from the light guide member 30, and the appearance seen from the front side in the front-rear direction can be further improved. Further, in the vehicular lamp 10, the light guide member 30 can be illuminated so as to border the outer lens 13, so that it is easy to satisfy a function required for the clearance lamp 17 (such as a luminance distribution defined by laws and regulations). Can be.

  Therefore, in the vehicular lamp 10 according to the embodiment of the present invention, the light sources 41 (411, 412) facing the incident end portions 31, 32 sandwiching the lamp unit (turn lamp unit 16) in the annular light guide member 30 are provided. In addition, the inner diameter dimension of the light guide member 30 can be reduced while suppressing the influence of heat on the LED substrate 43.
