A portion of the conductive member 11 exposed from the first surface portion 21 a of the mounting portion 21 serves as the electrode pad 13 . An electronic element such as the light emitting element 30 is attached to the electrode pad 13 by soldering.
That is, solder paste is applied to the electrode pads 13 arranged on the first surface portion 21a of the mounting portion 21, electronic elements such as the light emitting element 30 are arranged, and then heated in a reflow oven. Thereby, an electronic element such as the light emitting element 30 can be attached to the electrode pad 13 . In order to perform the above reflow process, the first surface portion 21a of the mounting portion 21 is a flat surface with substantially no steps.
In addition, it is preferable to use an LED or an organic EL light source for the light emitting element 30 from the viewpoint of miniaturization, low power consumption, and low heat generation. good too.

In addition, engaging claw portions 23 projecting outward are formed on the left and right side portions 21c of the mounting portion 21, respectively. The engaging claw portion 23 is a portion that engages with the engaging hole portion 50 (see FIGS. 1 and 2) of the cover member 40 . As shown in FIG. 2, the engaging claw portion 23 has an inclined portion 23a formed at the upper portion thereof so that the mounting portion 21 can be easily inserted into the cover member 40 when the mounting portion 21 is inserted into the cover member 40.

The lens portion 47 is formed in a curved shape that swells in a direction away from the light emitting element 30, and refracts light incident from the light emitting element 30 when transmitting the light.
Note that the lens portion 47 may be either a convex lens or a concave lens. For example, when the lens portion 47 is a convex lens, the light transmitted through the lens portion 47 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 47, the light transmitted through the lens portion 47 is emitted to the outside while being diffused. In addition, the cover member 40 is made of a transparent resin. Therefore, the lens portion 47 is transparent and can transmit light.

The upper surface portion 43 constitutes the upper surface of the cover member 40 and serves as a surface facing the upper surface of the mounting portion 21 of the holding member 20 . The upper surface portion 43 is formed in a substantially flat plate shape.

The side surface portions 44 constitute left and right side surfaces of the cover member 40 . The left and right side portions 44 are formed symmetrically and have substantially the same configuration. Therefore, the left side surface portion 44 will be described below.

A guide portion 52 is formed to support the end portion of the first surface portion 21a and guide the mounting portion 21 when the mounting portion 21 is inserted (FIG. 7). The engaging hole portion 50 is a rectangular hole, and the cover member 40 is fixed to the holding member 20 by engaging the engaging claw portion 23 with the engaging hole portion 50 .

The slit 51 restricts movement of the cover member 40 with respect to the holding member 20 in the insertion direction (direction of arrow C in FIG. 2). Here, the “insertion direction” is the direction in which the holding member 20 is moved when the cover member 40 is attached to the holding member 20 . In other words, the normal direction of the upper surface portion 43, which is the upward direction in FIG. 1 (direction of arrow C in FIG. 2) in the present embodiment, corresponds to the above-described "insertion direction".

The engagement hole portion 50 is a mechanism for attaching the mounting portion 21 to a predetermined position of the cover member 40 . The predetermined position is, for example, a position where the lens center of the lens portion 47 of the cover member 40 substantially coincides with the optical axis of the light emitting element 30 attached to the mounting portion 21 . By engaging the engaging claw portion 23 of the mounting portion 21 with the engaging hole portion 50 , the light emitting element 30 is positioned at the center of the lens portion 47 .

The guide portion 52 is formed along the direction of inserting the mounting portion 21 into the cover member 40 (direction of arrow C in FIG. 2). Specifically, as shown in FIG. 7, the guide portion 57 is a convex portion extending in the insertion direction. The mounting portion 21 is attached by the guide portion 52 so as to be positioned on the back portion 42 side.

Further, the guide portion 52 restricts the movement of the mounting portion 21 into the cover member 40 in the direction perpendicular to the insertion direction (here, the front-rear direction). That is, the first surface portion 21a of the mounting portion 21 is supported by the guide portion 57, and the second surface portion 21b of the mounting portion 21 comes into close contact with the rear surface portion of the cover member 40, thereby preventing displacement in the front-rear direction. can be suppressed.

The back surface portion 42 constitutes the back surface of the cover member 40 . It is a portion positioned to face the second surface portion 21 b of the mounting portion 21 . The rear surface portion 42 is formed in a size that covers the second surface portion 21 b of the mounting portion 21 . The exposed portion 16 of the conductive member 11 is exposed on the second surface portion 21b of the mounting portion 21, and a plurality of pin holes 18 are formed.

The back surface portion 42 is provided so as to cover the plurality of exposed portions 16 and the plurality of pin holes 18 on the second surface portion 21b. A slit 51 extending from the end (base end 53 ) on the opening 45 side in the insertion direction (upward direction) of the mounting portion 21 is formed. Then, when the mounting portion 21 is inserted, the protruding portion 25 protruding from the second surface portion 21b of the mounting portion 21 is engaged with the slit 51 . As shown in FIG. 1, the projecting portion 25 and the slit 51 are elongated along the direction in which the holding member 20 is inserted into the cover member 40 (direction of arrow C). With the mounting portion 21 as a cover member, the protruding portion 25 slides in the slit 51 , and the slit 51 is closed by the protruding portion 25 without a gap. Therefore, entry of water and dust into the inside of the cover member 40 from the back surface portion 42 is suppressed.
Further, when the engaging claw portion 23 contacts the opening portion 45 when the mounting portion 21 is inserted, the slit 51 allows the cover member 40 to bend in the left-right direction (directions of arrows A and B in FIG. 1). It's becoming Thereby, the mounting portion 21 is easier to insert than when the slit 51 is not provided.
