The light emitting unit mounting recess 111 extends toward the opening edge of the light emitting unit mounting recess 111.

The side edge portion 112 includes, for example, a first side edge portion 112a and a second side edge portion 112b shown in FIG. The side edge portion 112 has a protruding shape that protrudes toward the light emitting unit 20. Note that it is only necessary that at least one of the first side edge 112a and the second side edge 112b has a protruding shape that protrudes toward the light emitting unit 20 (that is, toward the -Z direction in FIG. 6).
The protruding shape here has, for example, an “L” shape that extends outward from each end in the short direction of the bottom plate portion 114 and then is folded outward. In addition, the part extended | stretched from each end of the baseplate part 114 is equivalent to the above-mentioned inner wall, and the folded part which comprises "L" character is called a folding | turning part.

As shown in FIG. 6B, the first side plate 12 a is attached so as to cover one end of the attachment member 11. The second side plate 12 b is attached so as to cover the other end of the attachment member 11. By attaching the first and second side plates 12a and 12b to the attachment member 11, the light emitting unit attachment recess 111 and the opening are formed.
That is, the “light emitting unit mounting recess 111” indicates a space surrounded by the bottom plate portion 114, the first side edge portion 112a and the second side edge portion 112b, and the first side plate 12a and the second side plate 12b.

  In addition, the “opening” is a folded portion (top portion) of the first side edge portion 112a and the second side edge portion 112b, and an edge portion on the opposite side to the mounting surface in the first side plate 12a and the second side plate 12b. Indicates the enclosed area.

As shown in FIGS. 7A and 7B, the instrument body 10 may include a position regulating member 113 that regulates the mounting position of the light emitting unit 20. The position restricting member 113 may be disposed in the light emitting unit mounting recess 111.
The position regulating member 113 comes into contact with the light emitting unit 20 when the light emitting unit 20 is attached to the instrument body 10. Thereby, the light emitting unit 20 is positioned at a predetermined position in the light emitting unit mounting recess 111.

  For example, as shown in FIG. 7A, the position regulating member 113 may be provided so as to protrude from the inner wall constituting the light emitting unit mounting recess 111 into the light emitting unit mounting recess 111. At this time, the position restricting member 113 is made of a metal material or the like fixed to the inner wall constituting the light emitting unit mounting recess 111 and is formed as a separate member from the light emitting unit mounting recess 111.

  Further, the position restricting member 113 may be formed by bending the metal plate of the mounting member 11 so as to be formed integrally with the side edge portion 112. Specifically, by forming a notch in a part of the inner wall constituting the light emitting unit mounting recess 111 and bending the metal plate so that the notch protrudes into the light emitting unit mounting recess 111, for example, a U-shaped cross section Or the position control member 113 which is a protrusion part of a U-shaped cross section can be formed.

Further, the position restricting member 113 may be disposed as a separate member on the side plate 12 constituting the light emitting unit mounting recess 111. Alternatively, for example, as illustrated in FIG. 7B, the position restriction member 113 may be formed integrally with the side plate 12.
At this time, the position regulating member 113 is provided in a state of protruding from the side plate 12. Specifically, when the light emitting unit 20 is attached to the instrument main body 10, a part of the side plate 12 is partly disposed on the light emitting unit mounting recess 111 in a facing region (region indicated by a dotted line in FIG. 7B) facing the light emitting unit 20. The position restricting member 113 is formed by bending toward the front.

As shown in FIG. 6B, the spring portion 13 is fixed to the bottom plate portion 114 of the attachment member 11, for example. The spring portion 13 is used to maintain the state where the light emitting unit 20 enters the light emitting unit mounting recess 111 of the instrument body 10 by engaging with a spring receiving portion 27 of the light emitting unit 20 described later.
Specifically, the first spring portion 13 a is engaged with the first spring receiving portion 27 a of the light emitting unit 20, and the second spring portion 13 b is engaged with the second spring receiving portion 27 b of the light emitting unit 20. That is, the 1st spring receiving part 27a and the 2nd spring receiving part 27b, the 1st spring part 13a, and the 2nd spring part 13b are the attachment states which maintain the state which attached the light emission unit 20 to the instrument main body 10 (attachment member 11).

Specifically, the power supply cable 40 led out from the attached surface such as a ceiling or a wall is electrically connected to a power supply unit 28 described later via the terminal block 14. The terminal block 14 is attached to the attachment member 11 with screws or the like, for example.

  The suspension bolt 30 is inserted into the suspension bolt hole 15 in order to attach the instrument body 10 to the surface to be attached such as a ceiling or a wall with the suspension bolt 30 shown in FIGS. 4 (A) and 4 (B). It is the provided hole.

  The power supply cable hole 16 is a hole provided to draw the power supply cable 40 led out from the mounting surface such as the ceiling or wall into the light emitting unit mounting recess 111 of the instrument body 10.

[Light emitting unit]
Hereinafter, the configuration of the light emitting unit 20 will be described.
FIG. 8 is a perspective view showing an external 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.
FIG. 10 is a plan view for explaining the light emitting element substrate 23 provided in the light emitting unit 20.
FIG. 11 is a perspective sectional view of the AA ′ section shown in FIG. 10.
12 is an enlarged perspective view showing a part of the light-emitting element support member 24 on the substrate support region 24a side shown in FIGS. 4A and 4B.
FIG. 13 is an exploded perspective view illustrating the configuration of the power supply unit 28 of the light emitting unit 20. In addition, in order to understand easily, the other part of the light emission unit 20 is also illustrated.
FIG. 14 is a cross-sectional perspective view illustrating the configuration of the reflecting member 29 of the light emitting unit 20.

As shown in FIG. 8, FIG. 4 (A), and FIG. 4 (B), the light emitting unit 20 includes a light emitting element 21 and a translucent cover 22 (22a, 22b, and 22c). 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 support member 24, a substrate fixing member 25 (25a to 25n), a screw 26, and a spring receiving portion. 27 (27a and 27b), a power supply unit 28, and a reflecting member 29 may be provided.
4 (A) and 4 (B), only the screw 26 for fixing the substrate fixing member 25a is provided with a reference symbol, and the screw for fixing the substrate fixing member 25n from the substrate fixing member 25b is provided with a reference symbol. Omitted.

Hereinafter, each part of the light emitting unit 20 will be described in detail.
The translucent cover 22 covers the light emitting element 21 and has a shape that enters the instrument body 10 when the light emitting unit 20 is attached to the instrument body 10. Here, the translucent cover 22 has a long shape, and has a “U” shape as shown in FIG. 9 in a cross section perpendicular to the longitudinal direction except for the end portion in the longitudinal direction. Further, the translucent cover 22 has a function of diffusing light emitted from the light emitting element 21.

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

Further, as shown in FIG. 9, the main cover 22 a of the translucent cover 22 includes a light transmission part 221 that transmits light emitted from the light emitting element 21, and a penetration part 222 that enters the instrument body. The entry portion 222 includes a first entry portion 222a and a second entry portion 222b.
That is, the main cover 22a has the entering portion 222 at the end portion of the mounting member 11 on the side close to the bottom plate portion 114 in the cross section orthogonal to the longitudinal direction. The amount of entry of the entry portion 222 is greater than the amount of deflection of the light emitting unit 20 when the light emitting unit 20 is attached to the instrument body 10.

  The entrance 222 that is a part of the translucent cover 22 enters the light emitting unit mounting recess 111 of the fixture body 10, so that it is difficult for the illumination device to have a poor appearance even when the light emitting unit 20 is bent. This is because only the entering portion 222 of the translucent cover 22 that has entered the light emitting unit mounting recess 111 when the light emitting unit 20 is bent is exposed, and a gap is generated between the fixture body 10 and the light emitting unit 20. This is because it disappears.

  In the main cover 22a, an end portion on the opening side that forms a “U” shape having a cross-sectional shape is bent inward and downward. Here, the lower side is the side where the end opposite to the opening of “U” exists. The main cover 22a has an inner narrow shape that inclines inward as it approaches the portion bent from the lower side, except for the bent portion.

In addition, the main cover 22a has a protruding piece protruding 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 protruding piece corresponds to the length of the folded portion of the light emitting element support member 24 described later. Thereby, the site | part (fitting part) between the bending part of the edge part of the main cover 22a and a protrusion piece fits into the return part of the light emitting element support member 24, and the translucent cover 22 supports a light emitting element. It is attached to the member 24. In this attached state, the folded portion of the light emitting element support member 24 and the inner surface of the translucent cover 22 are in contact.
The entering portion 222 of the translucent cover 22 is included in a 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. Accordingly, 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 support member 24, and the translucent cover 22.

  The light emitting unit 20 is attached to the instrument main body 10 in a state in which the narrowed entry portion 222 is in contact with the inner wall surface of the light emitting unit mounting recess 111 of the instrument main body 10. At this time, it is sufficient that only a part of the entering portion 222 is in contact with the light emitting unit mounting recess 111, but the entire surface of the entering portion 222 may be in contact with the light emitting unit mounting recess 111.

  As shown in FIGS. 4A and 4B, the light emitting element substrate 23 is a plate-like member extending long in one direction, and a plurality of light emitting elements 21 are mounted on one surface. As shown in FIG. 10, the light emitting element substrate 23 may be configured by connecting a plurality of substrates (for example, the substrate 23a and the substrate 23b are connected).

  As shown in FIGS. 10 and 11, a wiring for supplying power to the light emitting element 21 is connected to the light emitting element substrate 23. The wiring 28d connects the light emitting element substrate 23 and the power supply unit 28 through a through hole 24c provided in a substrate supporting region 24a of the light emitting element supporting member 24 described later. The electric power converted by the power supply circuit of the power supply unit 28 is supplied to the light emitting element 21 through the wiring 28d. The wiring 23c shown in FIGS. 10 and 11 is a wiring for electrically connecting the substrate 23a and the substrate 23b in the case where the light emitting element substrate 23 is configured by a plurality (two) of substrates.

  The light emitting element support member 24 supports the light emitting element substrate 23 on which the light emitting element 21 is mounted. Note that the light emitting element support member may indirectly mount the light emitting element via the light emitting element substrate 23, or may directly mount the light emitting element. The light emitting element support member 24 also has a function of a heat sink that dissipates heat from the light emitting element 21.

  4A and 4B, the light emitting element support member 24 has a lower surface including a substrate support region 24a that supports the light emitting element substrate 23, and an upper surface 24b that fixes the power supply unit 28. doing. The substrate support region 24 a is formed wider than the width of the light emitting element substrate 23.

  Further, the light emitting element support member 24 is formed such that a substrate support region 24 a that supports the light emitting element substrate 23 is recessed toward the instrument body 10. That is, as shown in FIG. 14, the light emitting element support member 24 includes a flat plate portion in which the substrate support region 24 a exists, and a standing portion that stands on the translucent cover 22 side from the edge in the width direction of the flat plate portion. The inclined portion that inclines outwardly in the width direction as it is away from the flat plate portion from the standing tip of the standing portion, and is folded back from the inclined front end of the inclined portion toward the width direction end of the flat plate portion. It has a folded portion and a contact portion that is folded inward from the folded tip of the folded portion and contacts the folded portion. The light emitting element support member 24 fixes the light emitting element substrate 23 by the substrate fixing members 25 provided at both ends in the width direction of the light emitting element substrate 23 in the substrate support region 24a.

As shown in FIGS. 10 and 11, the light emitting element support member 24 includes a through hole 24c through which the wiring 28d connected to the substrate support region 24a passes. The through-hole 24c is provided outside the area where the light emitting element substrate 23 is arranged in the substrate support area 24a, or at a position where the power supply unit 28 is fixed on the back surface or the periphery thereof. By providing the through hole 24c at a position facing the power supply section 28 (position where the power supply section 28 is fixed), the wiring 28d led out from the power supply section 28 is not routed in a wide area on the light emitting element support member 24. It can be connected to the light emitting element substrate 23.
For this reason, the wiring 28d can be shortened, and the assemblability of the light emitting unit 20 is improved. Further, the light emitting element substrate 23 is covered with the translucent cover 22, and the wiring 28d passes through the through hole 24c. For this reason, the wiring 28 is not exposed to the outside, the safety is improved, and the double coating of the wiring becomes unnecessary.

  The substrate fixing member 25 is provided at a plurality of locations along the longitudinal direction at both ends of the long light emitting element substrate 23 in the substrate supporting region 24a of the light emitting element supporting member 24. As shown in FIGS. 4A and 4B and FIG. 12, in the present embodiment, a plurality of substrate fixing members 25 a to 25 n are provided at both ends of the light emitting element substrate 23. Hereinafter, the substrate fixing member 25 a to the substrate fixing member 25 n are referred to as the substrate fixing member 25.

As shown in FIG. 12, the substrate fixing member 25 has a locking claw protruding in the short direction of the light emitting element substrate 23 from the outside of the light emitting element substrate 23 onto the light emitting element mounting surface of the light emitting element substrate 23. Yes. An end surface (side surface) of the substrate fixing member 25 on the light emitting element substrate 23 side is provided so as to be in contact with or close to a side portion of the light emitting element substrate 23. The substrate fixing member 25 is fixed to the light emitting element support member 24 by screws 26, for example.
For this reason, the light emitting element substrate 23 is fixed so as not to float with respect to the light emitting element support member 24.

As shown in FIG. 13, the spring receiving portion 27 engages with the spring portion 13 (see FIG. 7B) of the instrument body 10, whereby a part of the light emitting unit 20 enters the light emitting unit mounting recess 111. Thus, it is used for maintaining the state where the light emitting unit 20 is attached to the instrument body 10. Specifically, the first spring receiving portion 27 a engages with the first spring portion 13 a of the instrument body 10, and the second spring receiving portion 27 b engages with the second spring portion 13 b of the instrument body 10.
That is, the spring part 13 (first spring part 13a and second spring part 13b) and the spring receiving part 27 (first spring receiving part 27a and second spring receiving part 27b) attach the light emitting unit 20 to the attachment member 11. It functions as an attachment state maintaining unit that maintains the state.
