Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an exploded perspective view of the lighting fixture 1 of the present embodiment, and FIG. 2 is an exploded side view thereof. The luminaire 1 includes a main unit 11 and a light source unit 12.
First, the main unit 11 includes an instrument main body 13 and a light shielding member 14. The instrument main body 13 is provided with a power terminal block 21 inside the housing, and a power connector (male) 22 is connected to the power terminal block 21. A pair of screw receivers 23 are formed inside the housing.

  The light shielding member 14 is a member in which a light shielding plate 31 is formed on one end edge side in the lateral direction. A pair of spring receivers 32 are provided on both ends of the light shielding member 14 in the longitudinal direction. The light shielding member 14 is provided with a pair of screw holes 33. The light shielding member 14 can be attached to the instrument main body 13 by passing the attachment screw 34 through the screw hole 33 and screwing it onto the screw receiver 23 of the instrument main body 13.

  The light source unit 12 is provided with a power supply device 42 with a built-in lighting circuit and a power supply connector (female) 43 connected to the power supply device 42 on the back surface 41 thereof. A pair of mounting springs 44 are provided on both ends of the light source unit 12 in the longitudinal direction on the back surface 41. The light source unit 12 can be elastically supported by the main body unit 11 by inserting the mounting spring 44 into the spring receiver 32 of the light shielding member 14. As a result, the back surface 41 of the light source unit 12 serves as a detachable surface of the light source unit 12 with respect to the main unit 11. A through hole 35 is formed in the light shielding member 14, and the power connector (male) 22 and the power connector (female) 43 can be connected via the through hole 35. Thereby, the power supply device 42 can receive power supply from the outside via the power supply terminal block 21.

Such a lighting fixture 1 can be used as wall washer lighting. In this case, as shown in FIG. 9, a plurality of lighting fixtures 1 are continuously arranged in the longitudinal direction and installed on the ceiling. To illuminate. In this case, the adjacent portion 51 between the adjacent lighting fixtures 1 should not open a space as much as possible so that the light from the lighting fixture 1 can reach the wall sufficiently and a region that becomes partially dark does not occur on the wall. To.
However, in the lighting fixture 1, when the length in the longitudinal direction of the light source unit 12 is shorter than the length in the longitudinal direction of the main unit 11, a problem occurs. That is, there is a problem that a dark portion in which light from the light source unit 12 does not sufficiently reach is generated in a region corresponding to the adjacent portion 51 between the lighting fixtures 1 on the wall.
Hereinafter, how the lighting apparatus 1 solves such a problem will be described.

FIG. 3A is a perspective view of the luminaire 1 as viewed from the front side of the light source unit 12. The front side of the light source unit 12 (the side opposite to the back surface 41) is covered with a light-transmitting cover 45 formed of a material that transmits light (for example, white translucent).
FIG. 3B is a perspective view of the luminaire 1 viewed from the front side of the light source unit 12 with the translucent cover 45 of FIG. FIG.3 (c) is the elements on larger scale of FIG.3 (b). As shown in FIGS. 3B and 3C, the light source unit 12 includes a plurality of LEDs (Light Emitting Diodes) 47 serving as light sources from one end to the other end in the longitudinal direction of the light source unit 12, in this example. It is arranged continuously. As a result, the light source unit 12 causes the plurality of LEDs 47 serving as the light sources to emit light, and emits light to the outside via the translucent cover 45.

  FIG. 4 is a top view of the main unit 11 (of the instrument main body 13). The upper surface of the main body unit 11 (apparatus main body 13) forms an attachment surface 25 for attaching the main body unit 11 to an attachment surface such as a ceiling of a building.

  FIG. 5 is an enlarged right side view of the luminaire 1. The back surface 41 of the light source unit 12 serving as an attachment / detachment surface of the light source unit 12 with respect to the main body unit 11 is inclined with respect to an attachment surface 25 for attaching the main body unit 11 to an attachment surface such as a ceiling. That is, in the example of FIG. 5, the back surface 41 is inclined downward from the left side to the right side, and forms an acute angle with respect to the mounting surface 25 so as to illuminate the wall surface 102 (FIG. 8).

  FIG. 6 is a front view of the luminaire 1 as viewed from the front side of the light source unit 12. FIG. 7 is a partially enlarged view of FIG. In the lighting fixture 1, the main unit 11 and the light source unit 12 have substantially the same length in the longitudinal direction. Therefore, the position of the outer surface 26a of the side plate 26 at both ends in the longitudinal direction of the instrument body 13 (main unit 11) and the position of the outer surface 46a of the side plate 46 at both ends in the longitudinal direction of the light-transmitting cover 45 of the light source unit 12 When the luminaire 1 is viewed from the front side of the light source unit 12, they are substantially matched (in particular, see FIG. 7).

  Here, the lengths of the main unit 11 and the light source unit 12 in the longitudinal direction are “substantially equal” when the light source unit 12 is turned off, compared to the length of the light source unit 12 in the longitudinal direction of the main unit 11. This includes cases where the length in the longitudinal direction is slightly shorter. That is, by turning on the light source unit 12, the temperature of the light source unit 12 rises, and the translucent cover 45 expands slightly due to heat. Although the main unit 11 also receives the heat of the light source unit 12 and expands slightly, the temperature rise is smaller than that of the translucent cover 45, so the light source unit 12 (translucent cover 45) is more expanded (linear expansion). Rate) is large. Therefore, when the light source unit 12 is turned off, the length in the longitudinal direction of the light source unit 12 is slightly shorter than the length in the longitudinal direction of the main body unit 11, but the light source unit 12 (translucent cover 45) is turned on when the light source unit 12 is turned on. The case where the length in the longitudinal direction of the main body unit 11 and the length in the longitudinal direction of the light source unit 12 are equal when thermally expanded is also included in the “substantially equal”.

  Further, as shown in FIG. 5, the side plates 26 at both ends in the longitudinal direction of the main unit 11 (the instrument body 13) emit light emitted from the side plates 46 at both ends in the longitudinal direction of the light transmitting cover 45 of the light source unit 12. The light source unit 12 protrudes from the main unit 11 so as not to obstruct.

Next, the effect | action of the lighting fixture 1 is demonstrated.
FIG. 8 is an explanatory diagram showing an installation state of the lighting fixture 1. The lighting fixture 1 can be used as wall washer lighting. That is, the luminaire 1 can be attached to the ceiling 101 by attaching the attachment surface 25 to the ceiling 101 with the ceiling 101 as the attachment surface. At this time, the lighting fixture 1 can be illuminated by attaching the lighting fixture 1 at a position close to the wall 102 so that the light source unit 12 faces the wall 102 side. Reference numeral 103 indicates light that illuminates the wall 102 with the luminaire 1.

FIG. 9 is an explanatory diagram showing the installation status of the lighting fixture 1. As shown in FIG. 9, a plurality of lighting fixtures 1 used as wall washer lighting can be installed side by side in the longitudinal direction.
In this case, the adjacent portion 51 between the adjacent lighting fixtures 1 avoids a space as much as possible, and the light from the lighting fixture 1 reaches the wall 102 sufficiently, and a partially darkened area is generated in the wall 102. Do not.

  When the lighting fixture 1 is installed in this way, the length of the lighting fixture 1 is substantially the same in the longitudinal direction of the main unit 11 and the light source unit 12 (FIG. 6, FIG. 7, etc.). A plurality of light source units 12 are continuously arranged without any gap. Therefore, it is possible to prevent the light from the light source unit 12 from sufficiently reaching the area corresponding to the adjacent portion 51 of the lighting fixtures 1 on the wall 102 and darkening the area.

  Further, in the luminaire 1, the side plates 26 at both ends in the longitudinal direction of the main unit 11 (the instrument body 13) do not block light emitted from the side plates 46 of the translucent cover 45 at both ends in the longitudinal direction of the light source unit 12. Thus, the light source unit 12 protrudes from the main body unit 11 (FIG. 5 etc.). Therefore, the light emitted from the light source unit 12 is not blocked by the side plate 26 of the main body unit 11 (the instrument main body 13). Therefore, also in this respect, since the light emitted from the light source unit 12 reaches the area corresponding to the adjacent portion 51 of the lighting fixtures 1 on the wall 102 sufficiently, the area can be prevented from becoming dark.

  Further, in the light source unit 12, a plurality of LEDs (Light Emitting Diodes) 47 serving as light sources are continuously arranged from one end to the other end in the longitudinal direction of the light source unit 12 (with appropriate gaps) ( FIG. 3 (b) (c)). Therefore, the amount of light does not become insufficient at both ends of the light source unit 12 in the longitudinal direction. Therefore, also in this respect, since the light emitted from the light source unit 12 reaches the area corresponding to the adjacent portion 51 of the lighting fixtures 1 on the wall 102 sufficiently, the area can be prevented from becoming dark.

  The attachment / detachment surface of the light source unit 12 with respect to the main body unit 11 is the back surface 41 of the light source unit 12. Therefore, the attachment portion (attachment spring 44) of the light source unit 12 to the main body unit 11 may block the side plate 46 of the light transmissive cover 45 of the light source unit 12 (because it forms part of the light transmissive cover 45). Absent. Therefore, also in this respect, since the light emitted from the light source unit 12 reaches the area corresponding to the adjacent portion 51 of the lighting fixtures 1 on the wall 102 sufficiently, the area can be prevented from becoming dark.

In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
For example, although the above-described lighting fixture 1 is illustrated as being installed on the ceiling 101, it may be installed on the floor to prove the wall 102.
Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Moreover, it is also possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
