(First embodiment)
The electric device according to the first embodiment is a projector 1 that converts electric power into light for irradiation. Referring to FIG. 1, the projector 1 includes a main body portion 10 in which a plurality of LEDs 2 that are light sources are incorporated, and a frame portion 20 that surrounds the main body portion 10 and guards the main body portion 10. The LED 2 functions as a conversion unit that converts electric power into light.

  1 and 2, the main body 10 includes a hollow disk-shaped housing 11, a disk-shaped transparent plate 12 disposed on the front surface side of the housing 11, and the housing 11 from the front surface side of the transparent plate 12. An attached cover member 13, a battery holding portion 14 formed on the rear surface side of the housing 11, and a battery pack 15 that is a battery for lighting the LED 2 are provided. In FIG. 2, (a) is a front view, (b) is a side view, (c) is a rear view, (d) is a top view, and (e) is a bottom view. . The transparent plate 12 functions as an output unit that outputs the light emitted from the LED 2 to the outside.

  A battery pack 15 containing a plurality of battery cells such as nickel metal hydride and lithium ions is detachably attached to the battery holding unit 14. A switch 16 is provided on the upper surface of the housing 11. The battery holding unit 14 is electrically connected to the battery pack 15 and the switch 16, and the lighting of the LED 2 is controlled according to the operation of the switch 16. A control board (not shown) is accommodated.

  Referring to FIG. 3, a printed circuit board 17, which is an LED board on which a plurality of LEDs 2 are mounted, is accommodated in the housing 11 with the mounting surface of the LEDs 2 facing the front side. As the transparent plate 12, an acrylic plate or glass plate having excellent transparency is used, and the transparent plate 12 serves as an irradiation surface for light emitted from the LED 2. A spacer 18 is provided between the transparent plate 12 and the printed circuit board 17, and is disposed to face the mounting surface of the LED 2 on the printed circuit board 17 with a predetermined interval. Therefore, the light emitted from the LED 2 passes through the transparent plate 12 that is the irradiation surface and is irradiated to the front side of the housing 11. A gap between the LED 2 mounted on the printed circuit board 17 and the transparent plate 12 serves as a heat radiation clearance for radiating heat generated from the LED 2.

  The cover member 13 is a member for preventing the transparent plate 12 from being damaged. 1 and 2A, the cover member 13 is disposed on the periphery of the transparent plate 12, that is, the irradiation surface, and covers the edge 131 that covers the periphery of the irradiation surface, and the transparent plate 12, that is, on the irradiation surface. And three bar-shaped bumper parts 132 that cover the irradiation surface. The bumper part 132 is arrange | positioned in the position which does not block the light emitted from LED2. That is, as shown in FIG. 4, when the irradiation angle of the LED 2 is “θ”, the heat radiation clearance between the LED 2 and the transparent plate 12 is “L0”, and the thickness of the transparent plate 12 is “L1”, the LED 2 emits light. The spread of the light is La = 2 (L0 + L1) * tan (θ / 2) on the surface of the transparent plate 12. Therefore, the irradiation area (area through which the light emitted from the LED 2 is transmitted) on the surface of the transparent plate 12 corresponds to the arrangement of the LED 2 and is a circle having a diameter La as shown by a one-dot chain line in FIG. It becomes. The shapes of the edge 131 and the bumper 132 of the cover member 13 are set so as to avoid the irradiation area on the surface of the transparent plate 12. The spacer 18 provided between the transparent plate 12 and the printed circuit board 17 is also disposed at a position facing the edge portion 131 and the bumper portion 132 of the cover member 13 while avoiding the irradiation region on the surface of the transparent plate 12. Has been.

  In the first embodiment, as shown in FIG. 1, four LED rows in which a plurality of LEDs 2 are arranged in the horizontal direction are arranged. The interval between the LED rows is set to be wider than 2 * La. Accordingly, it is possible to provide the bumper portions 132 by avoiding the irradiation areas between the LED rows. In addition, the space | interval between the bumper parts 132 is set to 2 * La or more avoiding an irradiation area | region. Further, when considering the thickness “L2” of the bumper portion 132, the interval between the bumper portions 132 is set to Lb = 2 (L0 + L1 + L2) * tan (θ / 2) or more, or the spread of the irradiated light It is good to provide an inclined surface corresponding to.

  Referring to FIG. 2, rotating shafts 19 are coaxially provided on both side surfaces of the housing 11, and a tripod hole 3 is formed on the lower surface of the housing 11. The rotation shaft 19 is located between the irradiation surface (transparent plate 12) and the battery pack 15, and is arranged in parallel to the printed circuit board 17 and the transparent plate 12, that is, in a direction orthogonal to the irradiation direction. The tripod hole 3 is formed on the lower surface of the housing 11 which is a portion other than the side surface supported by the frame portion 20 so that the main body portion 10 can be supported by the tripod without removing the frame portion 20 from the main body portion 10. It is configured. The pivot shaft 19 is pivotally supported by a support mechanism portion 21 incorporated in a part of the frame portion 20 as shown in FIGS. In FIG. 5, (a) is a front view, (b) is a side view, (c) is a rear view, and (d) is a top view.

  The frame portion 20 is disposed on both side surfaces of the main body portion 10, and a pair of side frames 22 that guard the side surfaces of the main body portion 10, a top frame 23 that connects upper ends of the pair of side frames 22, and a pair of side frames 22 includes a pair of bottom frames 24 that extend rearward from the lower ends of the 22 and serve as legs, and a connection frame 25 that connects the rear ends of the pair of bottom frames 24. The side frame 22, the top frame 23, and the bottom The frame 24 and the connection frame 25 are integrated so as not to move relative to each other. As shown in FIG. 5B, in the state where the front surface of the main body 10 provided with the transparent plate 12 serving as the output portion faces frontward, as shown in FIG. When the front side is viewed, the side frames 22 are located on the left and right sides of the main body 10, the top frame 23 is located above the main body 10, and the bottom frame 24 is located below the main body 10. . The support mechanism portion 21 is incorporated in a part of the side frame 22 and pivotally supports the rotation shaft 19 of the main body portion 10 so as to be substantially orthogonal to the side frame 22. The top frame 23 and the bottom frame 24 are substantially parallel to the rotation shaft 19 of the main body 10, and are not in contact with each other even if the main body 10 rotates about the rotation shaft 19, that is, the position of the main body 10. It is arranged outside the rotation area.

  The side frame 22 and the bottom frame 24 are substantially L-shaped when viewed from the side. The angle formed by the side frame 22 and the bottom frame 24 is set to an acute angle, and the center of gravity of the main body 10 is the side surface shown in FIG. 5B even if the main body 10 rotates about the rotation shaft 19. It is configured so as to be always located on the bottom frame 24 in view. As a result, the projector 1 can stand on its own in a state where the bottom frame 24 and the connection frame 25 serving as legs are grounded, that is, in a state where the first grounding surface defined by the pair of bottom frames 24 is installed on the ground. It is. In the first embodiment, the angle formed by the side frame 22 and the bottom frame 24 is set to approximately 60 degrees. In a state where the bottom frame 24 and the connection frame 25 are grounded and the projector 1 is self-supported, the rotation shaft 19, the bottom frame 24, and the connection frame 25 of the main body 10 are disposed substantially parallel to the ground plane. Thus, the main body 10 and the battery pack 15 can rotate with respect to the frame 20 without contacting the ground. Further, in a state where the bottom frame 24 and the connection frame 25 are grounded and the projector 1 is self-supported, the bottom frame 24 and the connection frame 25 are located on the rear side of the rotation shaft 19 of the main body 10. Therefore, by rotating the main body 10, the light irradiated from the front surface (transparent plate 12) side of the main body 10 is not blocked by the bottom frame 24 and the connection frame 25, and the irradiation direction is changed over a wide range on the front side. It can be moved up and down. Further, in a state where the bottom frame 24 and the connection frame 25 are grounded and the projector 1 is self-supporting, the top frame 23 is disposed substantially parallel to the ground plane. Accordingly, the top frame 23 is disposed at a position that is easily gripped by the user substantially above the main body 10 and functions as a handle for carrying the projector 1.

  As shown in FIGS. 5B and 5C, the connection frame 25 is formed with a claw portion 26 that protrudes substantially upward and forms an angle of approximately 90 degrees with the bottom frame 24. That is, the front surface of the main body 10 on which the transparent plate 12 serving as the output unit is provided from the front with respect to the first ground surface is disposed, and the claw portion 26 is provided from the rear with respect to the first ground surface. It has been. A recess 26 a extending in a direction substantially parallel to the rotation shaft 19 of the main body portion 10 is formed on the surface of the claw portion 26 facing the main body portion 10. Thereby, the nail | claw part 26 functions as a hook-shaped hook. As shown in FIG. 6, the projector 1 can be used in a state of being hung on the single pipe 40 by hooking the claw portion 26 on the single pipe 40 with the projector 1 upside down. In the state suspended from the single pipe 40, the recess 26 a contacts the single pipe 40, so that the rotation shaft 19 is positioned substantially parallel to the single pipe 40, and the light from the projector 1 Irradiation is performed in a direction intersecting 40, that is, in a direction substantially perpendicular to the direction. In addition, the connection frame 25 is positioned above the rotating shaft 19 of the main body 10 in a state where it is suspended from the single pipe 40. Therefore, by rotating the main body 10, the light irradiated from the front surface (transparent plate 12) side of the main body 10 can be moved in a wide range on the lower side without being blocked by the connection frame 25. it can. In the present embodiment, the concave portion 26a is formed of a partially cylindrical curved surface whose axial direction is substantially parallel to the rotation shaft 19 of the main body portion 10, and the curvature radius R of the concave portion 26a is a single pipe pipe. Since the standard is 48.6 mm in diameter, for example, the radius R is set to 24.3 mm. Even if the main body 10 rotates about the rotation shaft 19 in a state where the single pipe 40 having the radius R is in contact with the recess 26a, the claw 26 is connected to the main body 10 and the single pipe 40. It is arrange | positioned in the position which does not contact. That is, the claw portion 26 is disposed at a position away from the turning region of the main body portion 10 by at least twice the radius of curvature R of the concave portion 26a. Further, since the concave portion 26a is formed of a partially cylindrical curved surface, the claw portion 26 is placed in the left-right direction with respect to the single pipe pipe 40 in a state where the claw section 26 is hooked on the single pipe pipe 10, that is, It is easy to move along.

  Further, as shown in FIG. 7, the projector 1 has a second state defined by a state in which the top frame 23 and the claw 26 of the connection frame 25 are grounded, that is, the top frame 23 and the claw 26 of the connection frame 25. Even if the ground contact surface is installed on the ground, it can stand on its own. In a state in which the top frame 23 and the connection frame 25 are grounded and the projector 1 is self-supporting, the rotation shaft 19, the bottom frame 24, and the connection frame 25 of the main body 10 are disposed substantially parallel to the ground plane. The part 10 and the battery pack 15 can be rotated with respect to the frame part 20 without contacting the ground. Further, in a state where the top frame 23 and the connection frame 25 are grounded and the projector 1 is self-supported, the bottom frame 24 and the connection frame 25 are positioned below the rotation shaft 19 of the main body unit 10. Therefore, by rotating the main body 10, the light irradiated from the front surface (transparent plate 12) side of the main body 10 is not blocked by the bottom frame 24 and the connection frame 25, and the irradiation direction is changed over a wide range on the upper side. Can be moved.

  The frame part 20 is configured by a plurality of molded products by resin molding using a hard resin. The substantially U-shaped top frame 23 and the side frame 22 up to the support mechanism portion 21 are integrally configured by a molded product divided into two. Further, the bent portion including the side frame 22 and the bottom frame 24 from the support mechanism portion 21 to the connection frame 25 is also integrally formed by a molded product divided into two. Thereby, the number of molded products constituting the frame part 20 can be reduced, and the assembly process can be simplified.

Next, a usage example of the projector 1 will be described in detail with reference to FIGS. 8 to 10.
The projector 1 can set the irradiation direction at all angles in the vertical direction from directly above to directly below by rotating around the rotation shaft 19.
The setting of the irradiation direction at the time of horizontal irradiation from the upper oblique 45 degrees to the lower oblique 45 degrees can be handled in a state where the bottom frame 24 and the connection frame 25 are grounded and the projector 1 is made independent. FIG. 8 shows a state in which the bottom frame 24 and the connection frame 25 are grounded and the projector 1 is self-supported. In (a), the irradiation direction is set horizontally toward the front, (b) In FIG. 5, the irradiation direction is set downward 45 degrees forward, and in (c), the irradiation direction is set upward 45 degrees forward.

  As shown in FIG. 8 (a), a state where the irradiation surface is vertical and the irradiation direction is set to be horizontal toward the front is a home position considered to be most frequently used. In this home position, the battery pack 15 is disposed in a guard area that is an area surrounded by the outer periphery of the frame portion 20. That is, the battery pack 15 is disposed in a substantially triangular guard area having two sides of the side frame 22 and the bottom frame 24 in a side view seen from the side frame 22 side, and is in a space guarded by the frame portion 20. Located in. Therefore, even if the projector 1 falls or falls, the battery pack 15 is guarded by the frame portion 20 and no impact is directly applied to the battery pack 15. When the impact is directly applied to the battery pack 15, the battery pack 15 is heavy, and thus there is a high possibility that the mounting mechanism with the battery holding unit 14 is damaged. Therefore, the projector 1 is configured such that the side pack 22 and the bottom frame 24 of the frame unit 20 efficiently guard the battery pack 15 that is vulnerable to shock so that the shock does not directly act on the battery pack 15. Thus, the durability of the projector 1 is improved. Further, as shown in FIG. 8A, the front surface of the main body portion 10 provided with the transparent plate 12 serving as an output portion is provided in front of the support mechanism portion 21 constituting the side frame 22 (left direction in the drawing). In this state, the frame portion 20 has a first grounding surface extending substantially in the front-rear direction below the support mechanism portion 21, and a second grounding surface extending substantially vertically in the rear of the support mechanism portion 21. It is configured.

  As shown in FIG. 8 (b), the battery pack 15 includes the side frame 22 and the bottom frame in a side view as seen from the side frame 22 side even when the irradiation direction is set to be obliquely upward 45 degrees forward. 24 is arranged in a substantially triangular guard region having two sides. Therefore, even if the projector 1 falls or falls within the rotation range of FIGS. 8A to 8B, the battery pack 15 is guarded by the frame portion 20, and the impact does not directly act on the battery pack 15. .

  As shown in FIG. 8 (c), in a state where the irradiation direction is set downward 45 degrees obliquely forward, most of the rear side of the battery pack 15 in the side view seen from the side frame 22 side is The side frame 22 and the bottom frame 24 are arranged in a substantially triangular guard region having two sides. Therefore, even if the projector 1 falls or falls within the rotation range of FIGS. 8A to 8C, the impact on the rear side is guarded by the frame portion 20 and does not directly act on the battery pack 15. In the state shown in FIG. 8C, a part of the battery pack 15 protrudes forward from the side frame 22, that is, a part of the battery pack 15 is exposed outside the guard region. Since the housing 11 of the main body 10 protrudes outward from the battery pack 15, even if the projector 1 falls or falls forward, the impact is applied to the housing 11 and the cover member 13 first. The impact does not act directly on the pack 15.

  The setting of the irradiation direction at the time of upward irradiation from 45 degrees upward to right above can be handled in a state where the top frame 23 and the claw portion 26 of the connection frame 25 are grounded and the projector 1 is self-supporting. FIG. 9 shows a state where the top frame 23 and the claw portion 26 of the connection frame 25 are grounded and the projector 1 is self-supported. In FIG. 9A, the irradiation direction is directed upward 45 degrees obliquely forward. In (b), the irradiation direction is set directly above.

  As shown in FIG. 9 (a), in the state where the irradiation direction is set upward 45 degrees obliquely forward, the front surface of the main body portion 10 provided with the transparent plate 12 as the output portion is the guard region. Located outside, the battery pack 15 is located inside the guard area. In other words, the battery pack 15 is disposed in a substantially triangular guard region having two sides of the side frame 22 and the bottom frame 24 in a side view as viewed from the side frame 22 side. Accordingly, even if the projector 1 falls or falls in this state, the battery pack 15 is guarded by the frame portion 20 and no impact is directly applied to the battery pack 15.

  As shown in FIG. 9 (b), the battery pack 15 has two side frames 22 and two bottom frames 24 in the side view as seen from the side frame 22 side even when the irradiation direction is set to face directly upward. It is arranged in a substantially triangular guard area as a side. Therefore, even if the projector 1 falls or falls within the rotation range of FIGS. 9A to 9B, the battery pack 15 is guarded by the frame portion 20, and the impact does not directly act on the battery pack 15. .

  The setting of the irradiation direction at the time of downward irradiation from 45 degrees downward to right below can be dealt with by using the projector 1 while being suspended from the single pipe 40. FIG. 10 shows a state in which the projector 1 is suspended from the single pipe 40. In (a), the irradiation direction is set downward 45 degrees obliquely forward, and in (b), the irradiation direction. Is set right below. Note that, in a state where the claw portion 26 is hooked on the single tube pipe 40, both the battery pack 15 and the single tube pipe 40 are configured to be located inside the guard region covered with the outer periphery of the frame portion.

  As shown in FIG. 10 (a), in a state where the irradiation direction is set to a downward slant of 45 degrees forward, the battery pack 15 includes the side frame 22 and the bottom frame as viewed from the side frame 22 side. 24 is arranged in a substantially triangular guard region having two sides. Accordingly, even if the projector 1 falls or falls in this state, the battery pack 15 is guarded by the frame portion 20 and no impact is directly applied to the battery pack 15.

  As shown in FIG. 10B, the battery pack 15 has two sides of the side frame 22 and the bottom frame 24 in a side view as viewed from the side frame 22 even when the irradiation direction is set to be directly below. Are arranged in a substantially triangular guard area. Therefore, even if the projector 1 falls or falls within the rotation range of FIGS. 10A and 10B, the battery pack 15 is guarded by the frame portion 20, and the impact does not directly act on the battery pack 15. .

  As described above, when the projector 1 is normally used, the whole or most of the battery pack 15 has two sides of the side frame 22 and the bottom frame 24 in a side view as viewed from the side frame 22 side. It is arranged in a substantially triangular guard area. And even if the main-body part 10 rotates, the battery pack 15 protrudes out of a guard area | region only from the side frame 22 side, the bottom frame 24 side, the upper end part of the side frame 22, and the edge part of the bottom frame 24 are connected. It does not protrude outside the guard area from the side to be connected. Therefore, even if the projector 1 falls or falls, the impact on the rear side is guarded by the frame portion 20 and does not act directly on the battery pack 15. 8 (b) to 8 (c), that is, the bottom frame 24 is grounded, the transparent plate 12 of the main body 10 is vertical, and the irradiation direction is set to be frontward and horizontal. The protrusion amount of the housing 10 from the side frame 22 side to the outside of the guard region is always larger than the protrusion amount of the battery pack 15 from the side frame 22 side to the outside of the guard region in the rotation range of 45 degrees in the vertical direction. It is configured. With this configuration, even if the projector 1 falls or falls forward, the impact is applied to the housing 11 and the cover member 13 first, and the impact is not directly applied to the battery pack 15.

  Further, the rotation of the main body 10 may be limited to a range in which the protruding amount from the side frame 22 side of the housing 10 to the outside of the guard region exceeds the protruding amount from the side frame 22 side of the battery pack 15 to the outside of the guard region. it can.
