The configuration of the light emitting unit 20 will be described below.
FIG. 8 is a perspective view showing the appearance of the light emitting unit 20 from above.
FIG. 9 is a cross-sectional view of the lighting device 1 including the light emitting unit 20. As shown in FIG.
FIG. 10 is a plan view for explaining the light-emitting element substrate 23 included in the light-emitting unit 20. FIG.
11 is a perspective sectional view of the AA' section shown in FIG. 10. FIG.
FIG. 12 is an enlarged perspective view showing a part of the light emitting element supporting member 24 shown in FIGS. 4A and 4B on the side of the substrate supporting region 24a.
FIG. 13 is an exploded perspective view illustrating the configuration of the power supply section 28 of the light emitting unit 20. As shown in FIG. To facilitate understanding, other parts of the light emitting unit 20 are also shown.
FIG. 14 is a cross-sectional perspective view for explaining the configuration of the reflecting member 29 of the light emitting unit 20. As shown in FIG.

As shown in FIG. 8 and FIGS. 4A and 4B, the light emitting unit 20 includes a light emitting element 21, translucent covers 22 (22a, 22b and 22c), and a wireless module 50. FIG. In addition to the light emitting element 21 and the translucent cover 22, the light emitting unit 20 includes, for example, a light emitting element substrate 23, a light emitting element supporting member 24, a substrate fixing member 25 (25a to 25n), a screw 26, and a spring receiving portion. 27 (27a and 27b), a power source section 28, and a reflecting member 29 may be provided.
In FIGS. 4A and 4B, only the screws 26 for fixing the board fixing members 25a are denoted by reference numerals, and the screws for fixing the board fixing members 25b to 25n are denoted by reference numerals. omitted.

Each part of the light emitting unit 20 will be described in detail below.
The light-transmitting cover 22 covers the light-emitting element 21 and has a shape that fits into the fixture body 10 when the light-emitting unit 20 is attached to the fixture body 10 . Here, the translucent cover 22 has a long shape, and except for the ends in the longitudinal direction, the cross section orthogonal to the longitudinal direction has a "U" shape as shown in FIG. Also, the translucent cover 22 has a function of diffusing the light emitted from the light emitting element 21 .

As shown in FIGS. 4A and 4B, the translucent cover 22 includes a main cover 22a covering the light emitting element 21, a first end cover 22b and a second end cover 22c. The first end cover 22b is attached to cover one end of the main cover 22a. The second end cover 22c is similarly attached so as to cover the other end of the main cover 22a.

Further, as shown in FIG. 9, the main cover 22a of the translucent cover 22 has a light transmitting portion 221 that transmits light emitted from the light emitting element 21, and a recessed portion 222 that enters the fixture body. The entry portion 222 includes a first entry portion 222a and a second entry portion 222b.
That is, the main cover 22a has an indentation portion 222 at the end portion of the mounting member 11 closer to the bottom plate portion 114 in a cross section orthogonal to the longitudinal direction. It should be noted that the amount of insertion of the recessed portion 222 is greater than the amount of bending of the light emitting unit 20 when the light emitting unit 20 is attached to the fixture main body 10 .

Since the recessed portion 222, which is a part of the translucent cover 22, enters the light-emitting unit mounting recess 111 of the fixture body 10, even when the light-emitting unit 20 is bent, the appearance of the lighting device is less likely to be deteriorated. This is because when the light-emitting unit 20 is bent, only the recessed portion 222 of the light-transmitting cover 22 that has entered the light-emitting unit mounting recess 111 is exposed, and a gap is created between the fixture main body 10 and the light-emitting unit 20. because it will disappear.

The main cover 22a is bent inward and downward at the opening-side end that forms a "U"-shaped cross section. Down here is the side where the end of the "U" opposite the opening lies. The main cover 22a, except for the bent portion, has a cross section that tapers inward toward the bent portion from below.

In addition, the main cover 22a has a protruding piece that protrudes inward at a portion away from the end on the opening side in a cross section orthogonal to the longitudinal direction. As shown in FIG. 14, the distance between the end portion and the projecting piece corresponds to the length of the folded portion of the light emitting element supporting member 24, which will be described later. As a result, the portion (fitting portion) between the bent portion of the end portion of the main cover 22a and the projecting piece is fitted to the bent portion of the light emitting element support member 24, and the translucent cover 22 supports the light emitting element. It is attached to member 24 . In this attached state, the folded portion of the light emitting element supporting member 24 and the inner surface of the translucent cover 22 are in contact with each other.
The recessed portion 222 of the translucent cover 22 is included in the region where the folded portion of the light emitting element support member 24 and the inner surface of the translucent cover 22 are in contact with each other. Thereby, heat generated during light emission of the light emitting element 21 is conducted to the mounting member 11 via the light emitting element substrate 23 , the light emitting element supporting member 24 and the translucent cover 22 .
