That is, the shape, size, arrangement, etc. of the members described below can be changed and improved without departing from the scope of the present invention, and the present invention naturally includes equivalents thereof.

[First embodiment]
A lighting device 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 12. FIG.

First, an outline of each figure of FIGS. 1 to 12 will be described.

11 is a right side view of the holder 2. FIG.
FIG. 12 shows a door lining D on which the lighting device 1 is mounted.
In the following description, the “vertical”, “horizontal”, and “backward” directions are viewed with the cover member 5 facing upward and the lens unit 52 facing forward. It corresponds to each direction of "up and down", "left and right", and "back and forth" of the case.

As shown in FIGS. 1 to 5, the illumination device 1 includes a body portion 3 and a cover member 5 as main components. The illumination device 1 has a cover member 5 attached to a body portion 3 . Hereinafter, the configuration of the main body 3 will be described with reference to FIGS. 6 to 11, and then the cover member 5 and its mounting procedure will be described.

As shown in FIGS. 6 to 11, the main body 3 includes a holder 2, a light emitting element 7 and a conductive member 10 as main components.
The holder 2 has a mounting portion 2a to which the light emitting element 7 is attached, and a terminal accommodating portion 2b to accommodate the connection terminal configured as a part of the conductive member 10 .

The connection terminals are terminals that extend vertically and are connected to an external power supply circuit or control circuit. The terminal accommodating portion 2b has a hollow shape and accommodates the connection terminal of the conductive member 10 therein.

It should be noted that the conductive member 10 is an electric circuit held in a state where at least a portion thereof is inserted into the holder 2 . A part of the conductive member 10 becomes an electrode pad 12 exposed from the holder 2 , and an electronic element such as the light emitting element 7 and the resistance element 35 is attached to the electrode pad 12 .
Here, the conductive member 10 may be formed by molding, or may be formed by punching and bending.

The holder 2 is formed by injection molding a resin material with the conductive member 10 inserted therein (that is, by insert molding). For example, a liquid crystal polymer, PBT (polybutylene terephthalate), PPS (polyphenylene sulfide), or the like may be used as the resin material.

FIG. 7 shows the holder 2 formed by injection molding with the conductive member 10 inserted. Although not shown in FIG. 7, a plurality of holders 2 are connected to the conductive member 10. As shown in FIG. Then, by cutting the connecting portion 11 that connects the conductive member 10 and the holder 2, the individual holders 2 are divided.

At this time, the cut portion of the connecting portion 11 is exposed from the holder 2 to the outside. In this embodiment, portions of the conductive member 10 are exposed from each of the upper surface 21b, the right side surface 21c, and the left side surface 21d of the holder 2. As shown in FIG.
Specifically, exposed portions 11 a , 11 b , 11 c , 11 d , 11 e , and 11 f , which are part of the conductive member 10 , are exposed from the holder 2 .

The above exposed portions are exposed from the second surfaces (upper surface 21b, right side surface 21c, left side surface 21d) different from the front surface 21a (corresponding to the first surface) of the holder 2 .
More specifically, the exposed portion 11a and the exposed portion 11b are exposed from the upper surface 21b. Also, the exposed portion 11c and the exposed portion 11d are exposed from the right side surface 21c. The exposed portion 11e and the exposed portion 11f are exposed from the left side surface 21d.

Further, as shown in FIG. 8, a convex portion 24 that protrudes outward (upward) is formed between the exposed portion 11a and the exposed portion 11b.
The convex portion 24 protrudes outward beyond the exposed portions 11a and 11b. That is, the exposed portions 11 a and 11 b are located inside the convex portion 24 .
In other words, as shown in FIG. 8, the convex portion 24 is positioned at the outermost peripheral portion 30 of the holder 2 when viewed from the front. The outermost peripheral portion 30 corresponds to a circumscribing rectangle of the holder 2 when viewed from the front.

Further, a convex portion 23 protruding outward (to the left) is formed on the left side of the exposed portion 11a. Similarly, a convex portion 23 is formed on the right side of the exposed portion 11b so as to protrude outward (rightward).
The protrusion 23 is also located at the outermost peripheral portion 30 of the holder 2, like the protrusion 24. As shown in FIG.
That is, the exposed portions 11 a and 11 b are located inside the outermost peripheral portion 30 . In this manner, the exposed portions 11a and 11b are less likely to come into contact with an external object because the adjacent convex portions 23 and 24 serve as barriers. Therefore, for example, it is possible to reduce the risk of a short circuit caused by a conductor such as a metal contacting the exposed portions 11a and 11b.

In this way, the convex portions 23 and 24 function as protective portions that protect the exposed portions 11a and 11b. Here, the above-mentioned "protection" has effects such as reducing the possibility of external objects coming into contact with the exposed portions 11a and 11b, softening the impact, and preventing short circuits. It is an effect to be exhibited.

In addition, the exposed portion 11c is exposed from a recessed portion 25 formed in the right side surface 21c. In other words, the exposed portion 11c is arranged in the recess 25 formed in the right side surface 21c. Specifically, the exposed portion 11 c is arranged to be exposed from the bottom of the recess 25 .

The recessed portion 25 is a portion that is recessed one step inward from the reference surface (the surface on which the engaging claw 28 is formed) of the right side surface 21c. The tip of the exposed portion 11 c is located inside the outermost peripheral portion 30 .
Since the exposed portion 11 c is arranged in the recess 25 , the walls on both sides of the recess 25 protect the exposed portion 11 c. The walls on both sides of the recess 25 are portions rising from the bottom of the recess 25 toward the outside of the lighting device 1 .
Furthermore, since the convex portion 23 is formed in the vicinity of the concave portion 25, the exposed portion 11c can be better protected.
A step portion 29 is formed between the concave portion 25 and the convex portion 23 . A stepped portion 29 adjacent to the convex portion 23 is located inside the convex portion 23 and outside the exposed portion 11c.

By arranging the exposed portion 11c in the concave portion 25 in this manner, the possibility of the exposed portion 11c coming into contact with an external object can be reduced. Therefore, it is possible to reduce the risk of a short circuit caused by contact of the metal conductor with the exposed portion 11c.
In other words, the concave portion 25 functions as a protective portion that protects the exposed portion 11c.

Also, the exposed portion 11d is exposed from a recess 26 formed in the right side surface 21c. In other words, the exposed portion 11 d is arranged in the recess 26 . Specifically, the exposed portion 11 d is arranged in a state of being exposed from the bottom of the recess 26 .

The recessed portion 26 is a portion that is recessed one step inward from the reference surface (the surface on which the engaging claw 28 is formed) of the right side surface 21c. A tip portion of the exposed portion 11 d is located inside the outermost peripheral portion 30 .
By disposing the exposed portion 11 d in the recess 26 in this manner, the walls on both sides of the recess 26 protect the exposed portion 11 d. The walls on both sides of the recess 26 are portions rising from the bottom of the recess 26 toward the outside of the lighting device 1 .

That is, by arranging the exposed portion 11d in the concave portion 26, it is possible to reduce the possibility that the exposed portion 11d comes into contact with an external object. Therefore, it is possible to reduce the risk of a short circuit caused by contact of the metal conductor with the exposed portion 11d.
In other words, the concave portion 26 functions as a protective portion that protects the exposed portion 11d.

Also, the exposed portion 11 d is provided between the engaging claw 28 and the terminal accommodating portion 2 b of the holder 2 . Since the engaging claw 28 and the outer end portion of the terminal accommodating portion 2b are located outside the exposed portion 11d, the exposed portion 11d can be protected by the arrangement described above.

The configuration of the left side surface 21d is bilaterally symmetrical with that of the right side surface 21c, and is substantially the same, so description thereof will be omitted.

A portion of the conductive member 10 exposed from the front surface 21 a of the holder 2 serves as the electrode pad 12 . An electronic element such as the light emitting element 7 is attached to the electrode pad 12 by soldering.
That is, a solder paste is applied to the electrode pads 12 arranged on the front surface 21a of the holder 2, and then electronic elements such as the light emitting element 7 are arranged and then heated in a reflow oven. Thereby, an electronic element such as the light emitting element 7 can be attached to the electrode pad 12 .
The front surface 21a of the holder 2 is a flat surface with no steps in order to perform the above reflow process.
In addition, it is preferable to use an LED or an organic EL light source for the light emitting element 7 from the viewpoint of miniaturization, low power consumption, and low heat generation. good too.

Further, the right side 21c and the left side 21d of the holder 2 are formed with engaging claws 28 projecting outward. The engaging claw 28 is a portion (engaging portion) that engages with the engaging portion 56 of the cover member 5 .
On the right side surface 21c, the engaging claw 28 is formed between the exposed portion 11c and the exposed portion 11d.
On the left side surface 21d, the engaging claw 28 is formed between the exposed portion 11e and the exposed portion 11f.

Next, a configuration of the cover member 5 and a method of attaching the cover member 5 to the main body 3 will be described with reference to FIGS. 1 to 5. FIG.

The cover member 5 includes a front portion 51, an upper surface portion 53, and left and right side portions 54 as main components.

The front portion 51 forms the front surface of the cover member 5 and faces the front surface 21 a of the holder 2 . The front portion 51 is sized to cover the front surface 21 a of the holder 2 . A front surface 21a of the holder 2 is a mounting surface on which electronic elements such as the light emitting element 7 are mounted.

A lens portion 52 is formed on the front portion 51 . The lens portion 52 is formed in a curved shape that swells in a direction away from the light emitting element 7, and refracts light incident from the light emitting element 7 when transmitting the light.
Note that the lens portion 52 may be either a convex lens or a concave lens. For example, when the lens portion 52 is a convex lens, the light transmitted through the lens portion 52 is converged and the condensed light is emitted to the outside. On the other hand, when a concave lens is used for the lens portion 52, the light transmitted through the lens portion 52 is emitted to the outside while being diffused.

The upper surface portion 53 constitutes the upper surface of the cover member 5 and serves as a surface facing the upper surface 21 b of the holder 2 . Specifically, the upper surface portion 53 is formed in a substantially flat plate shape.

The side surface portion 54 constitutes the side surface of the cover member 5 . The left and right side portions 54 are formed symmetrically and have substantially the same configuration. Therefore, the right side surface portion 54 will be described below.

The right side surface portion 54 is connected to the front surface portion 51 and the upper surface portion 53 and faces the right side surface 21 c of the holder 2 . Specifically, as shown in FIG. 1 , a projection 55 , an engaging portion 56 and a guide portion 57 are formed on the right side portion 54 .

The projecting portion 55 is, for example, an engaging claw, and is used as a fixing portion for fixing the illumination device 1 to an object to be attached.

The engaging portion 56 is a portion that engages with the engaging claw 28 formed on the right side surface 21 c of the holder 2 . Specifically, the engaging portion 56 is a rectangular hole, and the cover member 5 is fixed to the holder 2 by engaging the engaging claw 28 with the engaging portion 56 .

The engaging portion 56 restricts movement of the cover member 5 in the mounting direction with respect to the holder 2 . Here, the “attachment direction” is the direction in which the cover member 5 is moved when the cover member 5 is attached to the holder 2 . In other words, the normal direction of the front portion 51 and the direction opposite to the projecting direction of the lens portion 52 is the above-mentioned "mounting direction". Specifically, the forward direction in FIG. 1 corresponds to the above-mentioned "mounting direction".

The guide portion 57 is a mechanism for attaching the cover member 5 to a predetermined position of the holder 2 . Here, the predetermined position is, for example, a position where the lens center 52a of the lens portion 52 of the cover member 5 substantially coincides with the optical axis of the light emitting element 7 attached to the holder 2 .

The guide portion 57 is formed along the attachment direction for attaching the cover member 5 to the holder 2 . Specifically, as shown in FIG. 5, the guide portion 57 is a substantially rectangular slit extending in the mounting direction.
Here, a first end portion 57a, which is a front end portion of the guide portion 57 with respect to the mounting direction, is a tapered opening.
A second end portion 57b, which is a rear end portion of the guide portion 57 with respect to the mounting direction, is closed. That is, the second end portion 57 b of the guide portion 57 is formed at a position that does not reach the front portion 51 . More specifically, the second end portion 57b is formed at a substantially central position of the side portion 54 in the front-rear direction.

Here, the slit width (width in the vertical direction) of the guide portion 57 is slightly wider than the width (width in the vertical direction) of the convex portion 23 . Therefore, when attaching the cover member 5 to the holder 2 , the guide portion 57 functions as a slide groove along which the convex portion 23 of the holder 2 slides along the attachment direction. In other words, the convex portion 23 of the holder 2 functions as a sliding portion that slides along the guide portion 57 (slit).

Further, the guide portion 57 restricts the movement of the cover member 5 in the direction perpendicular to the mounting direction with respect to the holder 2 (vertical direction here). That is, when the convex portion 23 enters the guide portion 57 , the vertical movement of the convex portion 23 is restricted by the guide portion 57 . As a result, it is possible to prevent the cover member 5 from being displaced in the vertical direction with respect to the holder 2 both while the cover member 5 is attached to the holder 2 and after the attachment is completed.

Next, the positional relationship between the guide portion 57 and the engaging portion 56 will be described.
The guide portion 57 and the engaging portion 56 are arranged side by side in the direction perpendicular to the mounting direction on the side portion 54 .
That is, at least part of the guide portion 57 is located forward of the engaging portion 56 in the mounting direction. On the other hand, at least part of the guide portion 57 is located forward of the engaging portion 56 in the mounting direction.
Specifically, as shown in FIG. 5, the first end portion 57a of the guide portion 57 is located forward of the engaging portion 56 in the mounting direction. A second end portion 57b of the guide portion 57 is located behind the engaging portion 56 in the mounting direction.

Next, the positional relationship between the guide portion 57, the engaging portion 56 and the lens portion 52 will be described.
As shown in FIG. 2, the lens center 52a of the lens portion 52 is an area A1 surrounded by the left and right engaging portions 56 and the left and right guide portions 57 when viewed from the front with the front surface 21a to which the light emitting element 7 is attached. included in
In this manner, the lens center 52a of the lens portion 52 is surrounded by the left and right engaging portions 56 and the left and right guide portions 57, so that the lens portion 52 of the cover member 5 and the light emitting element attached to the holder 2 are mounted. 7 can be suppressed.
