Further, the front-rear direction is defined with the right side of the second end 100b of the luminaire 100 as the "front side" and the opposite side as the "rear side" when viewed from the front. However, these orientations do not limit the orientations during manufacturing, construction, and use of the luminaire of the present invention. The first direction D1 is the left direction, and the second direction D2 is the right direction.

In the present embodiment, the luminaire 100 will be described by taking the case where the luminaire 100 is installed on the ceiling surface C (FIG. 7) as an example. In this case, the base unit 300 is installed on the ceiling surface C (FIG. 7). The light source unit 200 is arranged below the base unit 300.

The light source unit 200 has a first light source unit end portion 200a in the first direction D1 (left direction). The base unit 300 has a first base unit end portion 300a in the first direction D1 (left direction).

Subsequently, the luminaire 100 of the present embodiment will be described with reference to FIG. FIG. 2 is an exploded perspective view of the lighting fixture 100 according to the present embodiment. Specifically, FIG. 2 shows the luminaire 100 viewed from below diagonally to the right.

First, the light source unit 200 will be described with reference to FIG. As shown in FIG. 2, the light source unit 200 includes a light emitting unit 1, a frame member 2, a cover member 3, a first cover closing member 4a, a second cover closing member 4b, and a first pressing member 5a. It has a second pressing member 5b. The light source unit 200 of the present embodiment further includes a first regulation unit 6a and a second regulation unit 6b. Further, the light source unit 200 has one terminal block 9, one power supply device 10, and two mounting brackets 13.

The light emitting unit 1 emits light. The light emitting unit 1 of the present embodiment includes a first light emitting module 1a and a second light emitting module 1b. The first light emitting module 1a has a plurality of light sources 11 and a wiring board 12. Similarly, the second light emitting module 1b also has a plurality of light sources 11 and a wiring board 12.

The light source 11 emits light. The light source 11 of the present embodiment has an LED (Light Emitting Diode) element as a light emitting element. More specifically, the light source 11 is, for example, an SMD (surface mount device) or a COB (chip on board).

The light source 11 is mounted on the wiring board 12. In the present embodiment, the light source 11 is mounted on the lower surface of the wiring board 12. In other words, the wiring board 12 is arranged so that the light source 11 faces downward. More specifically, the wiring board 12 is arranged so that the light emitting surface of the light emitting element faces the inner surface of the cover member 3. Wiring is formed on the wiring board 12. The wiring of the wiring board 12 supplies electric power to the light source 11. The wiring board 12 of the first light emitting module 1a and the wiring board 12 of the second light emitting module 1b are electrically connected.

The wiring board 12 has a long rectangular shape in the first direction D1 and the second direction D2 (horizontal direction). The first light emitting module 1a and the second light emitting module 1b are arranged so as to be arranged along the first direction D1 and the second direction D2. In the present embodiment, the first light emitting module 1a is arranged on the left side of the second light emitting module 1b. The second light emitting module 1b is arranged on the right side of the first light emitting module 1a.

The plurality of light sources 11 are arranged so as to be arranged in a row along the first direction D1 and the second direction D2 (left-right direction). However, the arrangement of the plurality of light sources 11 is not limited to one row. The plurality of light sources 11 may be arranged in two or more rows along the first direction D1 and the second direction D2, or may be arranged in a staggered pattern along the first direction D1 and the second direction D2.

The frame member 2 is a plate-shaped member and has a long rectangular shape in the first direction D1 and the second direction D2 (left-right direction). A light emitting unit 1 is attached to the frame member 2. More specifically, the light emitting unit 1 is attached to the lower surface of the frame member 2 so that the light source 11 faces downward. The light emitting portion 1 may be adhered to the frame member 2 by, for example, an adhesive, or may be fixed to the frame member 2 by a fastening member such as a screw.

The frame member 2 can be a metal member such as aluminum. In the present embodiment, the frame member 2 is made of metal and functions as a heat sink of the light emitting unit 1. The frame member 2 is molded by, for example, an extrusion molding method. By molding the frame member 2 by the extrusion molding method, the cross-sectional shape of the frame member 2 becomes constant from one end to the other end in the longitudinal direction of the frame member 2.

The cover member 3 covers the light emitting unit 1. More specifically, the cover member 3 is attached to the frame member 2 and covers the light emitting portion 1 from below. The cover member 3 is transparent or translucent, and transmits the light emitted from the light emitting unit 1. The cover member 3 is made of, for example, a milky white translucent material.

Specifically, the cover member 3 is a rectangular parallelepiped cylinder that is long in the first direction D1 and the second direction D2 (left-right direction). Further, the cover member 3 has a first cover opening end 3a and a second cover opening end 3b. The first cover opening end 3a is an opening end opened in the first direction D1 (left direction), and the second cover opening end 3b is an opening end opened in the second direction D2 (right direction).

The coefficient of thermal expansion of the cover member 3 is higher than the coefficient of thermal expansion of the frame member 2. Therefore, when the cover member 3 thermally expands due to the heat generated from the light emitting unit 1, the cover member 3 extends along the longitudinal direction (left-right direction) of the frame member 2. More specifically, when the cover member 3 thermally expands, the end portion (left end portion) of the cover member 3 on the first cover opening end 3a side extends (deforms) in the first direction D1. On the other hand, the end portion (right end portion) on the second cover opening end 3b side of the cover member 3 extends (deforms) in the second direction D2 when the cover member 3 thermally expands.

The cover member 3 is made of resin, for example. When the cover member 3 is a diffusion cover, the cover member 3 may be formed, for example, by molding a resin containing a light diffusion material. Alternatively, the cover member 3 may be formed by subjecting the surface of a resin molded product molded from a transparent resin to a light diffusion treatment. Here, the light diffusion treatment includes, for example, a fine unevenness forming treatment and a translucent white coating treatment. The fine unevenness forming process is a process for forming minute unevenness on the surface of the resin molded product. The translucent white coating process is a process of applying a translucent milky white paint to the surface of a resin molded product.

The first cover closing member 4a has a first cover closing portion 41a. The first cover closing portion 41a closes the opening end 3a of the first cover to form the first light source unit end portion 200a described with reference to FIG. In the present embodiment, the external dimensions of the first cover closing portion 41a viewed from the left side are substantially the same as the external dimensions of the first cover opening end 3a. Since the external dimensions of the first cover closing portion 41a viewed from the left side and the external dimensions of the first cover opening end 3a are substantially the same, a sense of unity between the cover member 3 and the first cover closing portion 41a can be obtained. Can be done. The first cover closing portion 41a is made of, for example, a synthetic resin.

Similarly, the second cover closing member 4b has a second cover closing portion 41b. The second cover closing portion 41b closes the second cover opening end 3b to form the second light source unit end portion 200b described with reference to FIG. In the present embodiment, the external dimensions of the second cover closing portion 41b as viewed from the right side are substantially the same as the external dimensions of the second cover opening end 3b. Since the external dimensions of the second cover closing portion 41b viewed from the right side and the external dimensions of the second cover opening end 3b are substantially the same, a sense of unity between the cover member 3 and the second cover closing portion 41b can be obtained. Can be done. The second cover closing portion 41b is made of, for example, a synthetic resin.

The first cover closing portion 41a and the second cover closing portion 41b may have the same color as the cover member 3. The first cover closing portion 41a and the second cover closing portion 41b are made of, for example, a milky white translucent material. Since the first cover closing portion 41a, the second cover closing portion 41b, and the cover member 3 have the same color, the cover member 3, the first cover closing portion 41a, and the second cover closing portion 41b have a sense of unity. Obtainable.

The first cover closing portion 41a and the second cover closing portion 41b may diffuse the light emitted from the light emitting portion 1. In this case, the first cover closing portion 41a and the second cover closing portion 41b may be formed, for example, by molding a resin containing a light diffusing material. Alternatively, the first cover closing portion 41a and the second cover closing portion 41b may be formed by subjecting the front surface or the back surface of the resin molded product molded with a transparent resin to light diffusion treatment.

When the cover member 3 is a diffusion cover, the first cover closing portion 41a and the first cover closing portion 41a and the first cover closing portion 41a and the first cover closing portion 41a so that the diffusion rate of the first cover closing portion 41a and the second cover closing portion 41b is substantially the same as the diffusion rate of the cover member 3. 2 The cover closing portion 41b may be formed. By making the diffusion rate of the first cover closing portion 41a and the second cover closing portion 41b substantially the same as the diffusion rate of the cover member 3, the cover member 3 and the first cover closing portion are lit when the luminaire 100 is lit. It is possible to obtain a sense of unity between the 41a and the second cover closing portion 41b.

The first cover closing portion 41a is pressed in the first direction D1 when the end portion (left end portion) on the first cover opening end 3a side of the cover member 3 extends in the first direction D1. Similarly, the second cover closing portion 41b is pressed in the second direction D2 when the end portion (right end portion) on the second cover opening end 3b side of the cover member 3 extends in the second direction D2.

The first cover closing member 4a is slidably attached to the frame member 2 in the first direction D1 and the second direction D2 (left-right direction). Therefore, when the cover member 3 is thermally expanded and the first cover closing portion 41a is pressed in the first direction D1, the first cover closing member 4a moves in the first direction D1. In other words, the position of the first cover closing member 4a is displaced in the first direction D1.

Similarly, the second cover closing member 4b is slidably attached to the frame member 2 in the first direction D1 and the second direction D2 (left-right direction). Therefore, when the cover member 3 is thermally expanded and the second cover closing portion 41b is pressed in the second direction D2, the second cover closing member 4b moves in the second direction D2. In other words, the position of the second cover closing member 4b is displaced in the second direction D2.

The first pressing member 5a has elasticity. The first pressing member 5a applies a pressing force to the first cover closing member 4a in the second direction D2 in response to the deformation of the cover member 3 in the first direction D1. Specifically, when the cover member 3 thermally expands and the first cover closing member 4a moves in the first direction D1 (left side), the first pressing member 5a is compressed and deformed. Specifically, the first pressing member 5a is elastically deformed. Therefore, the first pressing member 5a tries to return to the original shape. As a result, the pressing force in the second direction D2 is applied to the first cover closing member 4a by the force trying to return to the original shape of the first pressing member 5a.

Similarly, the second pressing member 5b has elasticity. The second pressing member 5b applies a pressing force to the second cover closing member 4b in the first direction D1 according to the deformation of the cover member 3 in the second direction D2. Specifically, when the cover member 3 thermally expands and the second cover closing member 4b moves in the second direction D2 (right side), the second pressing member 5b is compressed and deformed. Specifically, the second pressing member 5b is elastically deformed. Therefore, the second pressing member 5b tries to return to the original shape. As a result, the pressing force in the first direction D1 is applied to the second cover closing member 4b by the force trying to return to the original shape of the second pressing member 5b.

The first regulating unit 6a regulates the movement of the first pressing member 5a in the first direction D1 (left side) when the cover member 3 is thermally expanded. Therefore, according to the present embodiment, the first pressing member 5a is more reliably elastically deformed when the cover member 3 is thermally expanded.

Specifically, the first regulation unit 6a of the present embodiment has a first facing member 7a and a first fastening member 8a. The first facing member 7a faces the first pressing member 5a. Specifically, the first opposing member 7a is arranged at a position closer to the first cover closing portion 41a than the first pressing member 5a and faces the first pressing member 5a. The first fastening member 8a is fastened to the frame member 2 to fix the first facing member 7a. By fixing the first facing member 7a to the frame member 2, the movement of the first pressing member 5a in the first direction D1 can be more reliably regulated.

Similarly, the second regulating unit 6b regulates the movement of the second pressing member 5b in the second direction D2 (right side) when the cover member 3 is thermally expanded. Therefore, according to the present embodiment, the second pressing member 5b is more reliably elastically deformed when the cover member 3 is thermally expanded.

Specifically, the second regulation unit 6b of the present embodiment has a second facing member 7b and a second fastening member 8b. The second facing member 7b faces the second pressing member 5b. Specifically, the second opposing member 7b is arranged at a position closer to the second cover closing portion 41b than the second pressing member 5b and faces the second pressing member 5b. The second fastening member 8b is fastened to the frame member 2 to fix the second facing member 7b. By fixing the second facing member 7b to the frame member 2, the movement of the second pressing member 5b in the second direction D2 can be more reliably regulated.

The terminal block 9 is fixed to the frame member 2. More specifically, the terminal block 9 is fixed to the upper surface of the frame member 2. One end of an external power line (not shown) drawn into the lighting fixture 100 from the outside of the lighting fixture 100 is connected to the terminal block 9. The external power line (not shown) is connected to the terminal block 9, for example, before the light source unit 200 is attached to the base unit 300.

The power supply device 10 is fixed to the frame member 2. More specifically, the power supply device 10 is fixed to the upper surface of the frame member 2. The power supply device 10 is connected to the terminal block 9 via an internal power line 14 (FIG. 11). The AC voltage for transmitting the external power line (not shown) is energized to the internal power line 14 (FIG. 11) via the terminal block 9. The internal power line 14 (FIG. 11) transmits an AC voltage to the power supply device 10. The power supply device 10 generates electric power for causing the light source 11 to emit light from an AC voltage. The power supply device 10 of the present embodiment generates a DC voltage that causes the LED element to emit light from an AC voltage.

The mounting bracket 13 is fixed to the frame member 2. More specifically, the mounting bracket 13 is fixed to the upper surface of the frame member 2. The mounting bracket 13 is a member for mounting the light source unit 200 to the base unit 300. The mounting bracket 13 has an elastic member such as a leaf spring. In the present embodiment, one of the two mounting brackets 13 is arranged on the left side of the power supply device 10, and the other of the two mounting brackets 13 is arranged on the right side of the power supply device 10. In other words, the two mounting brackets 13 are arranged so as to sandwich the power supply device 10.

Subsequently, the base unit 300 will be described with reference to FIG. As shown in FIG. 2, the base unit 300 has a base member 310, two holding metal fittings 320, a first base closing member 330a, and a second base closing member 330b.

The base member 310 supports the light source unit 200. Specifically, the base member 310 supports the frame member 2 via the mounting bracket 13. In other words, the frame member 2 is attached to the base member 310 via the mounting bracket 13.

Specifically, the base member 310 is a rectangular parallelepiped cylinder that is long in the first direction D1 and the second direction D2 (left-right direction). The lower surface 310c of the base member 310 is open. Specifically, the lower surface 310c of the base member 310 has openings extending in the first direction D1 and the second direction D2 (left-right direction). The opening of the lower surface 310c is provided from one end to the other end in the longitudinal direction of the base member 310. The opening of the lower surface 310c communicates the inner space and the outer space of the base member 310. The base member 310 is molded, for example, by an extrusion molding method. By molding the base member 310 by the extrusion molding method, the cross-sectional shape of the base member 310 becomes constant from one end to the other end in the longitudinal direction of the base member 310.

The holding metal fitting 320 is arranged at a position corresponding to the mounting metal fitting 13 in the inner space of the base member 310. The holding metal fitting 320 is a member for holding the mounting metal fitting 13. The holding metal fitting 320 has an elastic member such as a leaf spring.

When the light source unit 200 is attached to the base member 310, the operator engages the mounting bracket 13 with the holding bracket 320 and causes the holding bracket 320 to hold the mounting bracket 13. As a result, the base member 310 (base unit 300) supports the light source unit 200. The dimensions of the mounting bracket 13 in the front-rear direction may be such that the mounting bracket 13 can pass through the opening of the lower surface 310c of the base member 310 when the light source unit 200 is mounted on the base member 310.

According to this embodiment, the light source unit 200 is attached to the base member 310 by elastic force. Therefore, the light source unit 200 is removable from the base member 310. Since the light source unit 200 is detachable from the base member 310, the light source unit 200 can be easily replaced. For example, it can be replaced with a light source unit 200 having different specifications. Further, when the light source unit 200 fails, the light source unit 200 can be removed from the base member 310 for repair, and the repaired light source unit 200 can be attached to the base member 310. In the case of a luminaire in which the light source unit and the base member cannot be separated, it is necessary to remove the luminaire set from the ceiling surface in order to replace or repair the light source unit. To remove the luminaire from the ceiling, you need to use a screwdriver to remove the screws that secure the luminaire to the ceiling. Therefore, the work of replacing the light source unit and the work of repairing the light source unit are very complicated. According to this embodiment, since it is not necessary to remove the base member 310 from the ceiling surface when replacing or repairing the light source unit 200, the work of replacing the light source unit and the repair of the light source unit are performed without using a screwdriver or the like. You can work. Therefore, the work becomes easy.

Further, according to the present embodiment, since the holding metal fitting 320 is arranged in the inner space of the base member 310, the power supply device 10 is arranged in the inner space of the base member 310. Therefore, the height of the lighting fixture 100 can be reduced.

The base member 310 has a first base opening end 310a and a second base opening end 310b. The first base opening end 310a is an opening end opened in the first direction D1 (left direction), and the second base opening end 310b is an opening end opened in the second direction D2 (right direction).

The first base closing member 330a has a first base closing portion 331a. The first base closing portion 331a closes the first base opening end 310a to form the first base unit end portion 300a described with reference to FIG. Similarly, the second base closing member 330b has a second base closing portion 331b. The second base closing portion 331b closes the second base opening end 310b to form the second base unit end portion 300b described with reference to FIG.

More specifically, the first base closing member 330a has a first fitting portion 340a.
