  The present invention relates to a light emitting unit having a plurality of semiconductor light emitting elements and a lighting device including the light emitting unit.

  2. Description of the Related Art Conventionally, lighting devices in which an illuminant such as an incandescent bulb or a fluorescent lamp is attached to a fixture main body and the fixture main body is attached to a mounting target surface such as a ceiling or a wall are widely used. In addition to the light emitter, a power supply circuit, a lighting control circuit, a wireless antenna, and the like are also arranged inside the lighting device. Since a conventional lighting device has a certain amount of space, a power supply circuit, a lighting control circuit, a wireless antenna, and the like can be freely installed therein.

  In recent years, it has been proposed that a light emitting diode (LED: Light Emitting Diode), which consumes less power than a conventionally used incandescent bulb or fluorescent lamp and has excellent durability, be used in a lighting device. . Since the LED is thinner than incandescent bulbs and fluorescent lamps, the lighting device can be made thinner.

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.

  The bottom plate portion 114 is opposed to a mounting surface of a construction material such as a ceiling or a wall, and a suspension bolt hole portion 15 for mounting the lighting device 1 on the mounting surface or a power supply cable in the lighting device 1. A power supply cable hole 16 or the like for drawing in is provided.

  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.

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 FIGS. 8, 4 </ b> A, and 4 </ b> B, the light emitting unit 20 includes a light emitting element 21, a translucent cover 22 (22 a, 22 b, and 22 c), and a wireless module 50. 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.
