Next, with reference to FIG. 2, the lighting fixture 100 of this embodiment will be described. FIG. 2 is an exploded perspective view of the lighting fixture 100 according to this embodiment. Specifically, FIG. 2 shows the luminaire 100 viewed from below and obliquely forward 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 portion 1, a frame member 2, a cover member 3, a first cover closing member 4a, a second cover closing member 4b, a first pressing member 5a, and a second pressing member 5b. The light source unit 200 of this embodiment further includes a first restricting portion 6a and a second restricting portion 6b. Also, 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 section 1 of this embodiment has a first light emitting module 1a and a second light emitting module 1b. The first light emitting module 1 a has a plurality of light sources 11 and a wiring board 12 . The second light emitting module 1b similarly has a plurality of light sources 11 and a wiring substrate 12. As shown in FIG.

The light source 11 emits light. The light source 11 of this 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 this 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 such 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 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 rectangular shape elongated 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 side by side along the first direction D1 and the second direction D2. In this 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 in a row along the first direction D1 and the second direction D2 (horizontal 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 zigzag pattern along the first direction D1 and the second direction D2.

The frame member 2 is a plate-like member and has a rectangular shape elongated in the first direction D1 and the second direction D2 (horizontal 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 section 1 may be adhered to the frame member 2 with an adhesive, for example, or may be fixed to the frame member 2 with a fastening member such as a screw.

The frame member 2 may be a member made of metal such as aluminum. In this embodiment, the frame member 2 is made of metal and functions as a heat sink for the light emitting section 1 . The frame member 2 is molded by, for example, extrusion molding. By forming 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 section 1 . More specifically, the cover member 3 is attached to the frame member 2 and covers the light emitting section 1 from below. The cover member 3 is transparent or translucent, and allows the light emitted from the light emitting section 1 to pass therethrough. The cover member 3 is made of, for example, a translucent milky white material.

Specifically, the cover member 3 is a rectangular parallelepiped cylindrical body elongated in the first direction D1 and the second direction D2 (horizontal 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 (leftward direction), and the second cover opening end 3b is an opening end opened in the second direction D2 (rightward 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 section 1 , the cover member 3 extends along the longitudinal direction (horizontal direction) of the frame member 2 . More specifically, when the cover member 3 thermally expands, the end (left end) 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 (right end) of the cover member 3 on the side of the second cover opening end 3b expands (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 by molding resin containing a light diffusion material, for example. Alternatively, the cover member 3 may be formed by applying a light diffusion treatment to the surface of a resin molded article molded from a transparent resin. Here, the light diffusion treatment includes, for example, fine unevenness formation treatment and translucent white painting treatment. The fine unevenness forming treatment is a process for forming fine unevenness on the surface of a resin molded product. The translucent white coating treatment is a treatment in which translucent milky white paint is applied to the surface of the resin molded product.

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

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 and constitutes the second light source unit end portion 200b described with reference to FIG. In the present embodiment, the outer dimensions of the second cover closing portion 41b viewed from the right side are substantially the same as the outer dimensions of the second cover opening end 3b. A sense of unity between the cover member 3 and the second cover closing portion 41b is obtained by making the outer dimensions of the second cover closing portion 41b viewed from the right side substantially the same as the outer dimensions of the second cover opening end 3b. can be done. The second cover closing portion 41b is made of synthetic resin, for example.

The first cover closing portion 41 a and the second cover closing portion 41 b 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 translucent milky white 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 are integrated. Obtainable.

The first cover closing portion 41 a and the second cover closing portion 41 b 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 resin containing a light diffusion material. Alternatively, the first cover closing portion 41a and the second cover closing portion 41b may be formed by subjecting the surface or the back surface of a resin molded product made of transparent resin to light diffusion treatment.

When the cover member 3 is a diffusion cover, the first cover closing portion 41a and the second cover closing portion 41a are arranged so that the diffusion coefficients of the first cover closing portion 41a and the second cover closing portion 41b are substantially the same as the diffusion coefficients of the cover member 3. A two-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, when the lighting fixture 100 is turned on, the cover member 3 and the first cover closing portion A sense of unity between 41a and the second cover closing portion 41b can be obtained.

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

The first cover closing member 4a is attached to the frame member 2 so as to be slidable in the first direction D1 and the second direction D2 (horizontal direction). Therefore, when the cover member 3 thermally expands 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 attached to the frame member 2 so as to be slidable in the first direction D1 and the second direction D2 (horizontal direction). Therefore, when the cover member 3 thermally expands 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 in the second direction D2 to the first cover closing member 4a according 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 (leftward), the first pressing member 5a is compressed and deformed. Specifically, the first pressing member 5a is elastically deformed. Therefore, the first pressing member 5a attempts to return to its original shape. As a result, the force of the first pressing member 5a to return to its original shape applies a pressing force in the second direction D2 to the first cover closing member 4a.

Similarly, the second pressing member 5b has elasticity. The second pressing member 5b applies a pressing force in the first direction D1 to the second cover closing member 4b 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 (to the right), the second pressing member 5b is compressed and deformed. Specifically, the second pressing member 5b is elastically deformed. Therefore, the second pressing member 5b attempts to return to its original shape. As a result, the force of the second pressing member 5b to return to its original shape applies a pressing force in the first direction D1 to the second cover closing member 4b.

The first restricting portion 6a restricts movement of the first pressing member 5a in the first direction D1 (leftward) when the cover member 3 thermally expands. Therefore, according to the present embodiment, when the cover member 3 thermally expands, the first pressing member 5a is elastically deformed more reliably.

Specifically, the first restricting portion 6a of the present embodiment has a first opposing member 7a and a first fastening member 8a. The first facing member 7a faces the first pressing member 5a. Specifically, the first facing 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 opposing member 7a. By fixing the first opposing member 7a to the frame member 2, the movement of the first pressing member 5a in the first direction D1 can be more reliably restricted.

Similarly, the second restricting portion 6b restricts movement of the second pressing member 5b in the second direction D2 (rightward) when the cover member 3 thermally expands. Therefore, according to the present embodiment, when the cover member 3 thermally expands, the second pressing member 5b is elastically deformed more reliably.

Specifically, the second restricting portion 6b of the present embodiment has a second opposing member 7b and a second fastening member 8b. The second facing member 7b faces the second pressing member 5b. Specifically, the second facing 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 opposing member 7b. By fixing the second opposing member 7b to the frame member 2, the movement of the second pressing member 5b in the second direction D2 can be more reliably restricted.

A terminal block 9 is fixed to the frame member 2 . More specifically, the terminal block 9 is fixed to the top surface of the frame member 2 . The terminal block 9 is connected to one end of an external power line (not shown) drawn into the interior of the lighting fixture 100 from the outside of the lighting fixture 100 .

An internal power line 14 ( FIG. 11 ) carries alternating voltage to power supply 10 . The power supply device 10 generates power for causing the light source 11 to emit light from AC voltage. The power supply device 10 of this embodiment generates a DC voltage for causing an 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 top 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 this 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 .

Next, 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.

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

Specifically, the base member 310 is a rectangular parallelepiped cylindrical body elongated in the first direction D1 and the second direction D2 (horizontal direction). A 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 (horizontal direction).

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 detachable from the base member 310 . Since the light source unit 200 is detachable from the base member 310, replacement of the light source unit 200 is facilitated. For example, the light source unit 200 can be replaced with one having different specifications. Further, when the light source unit 200 breaks down, 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 addition, in the case of lighting fixtures in which the light source unit and the base member cannot be separated, it is necessary to remove the set of lighting fixtures from the ceiling surface in order to replace or repair the light source unit. To remove the lighting equipment from the ceiling surface, it is necessary to remove the screw that secures the lighting equipment to the ceiling surface with a screwdriver. Therefore, the work of replacing the light source unit and the work of repairing the light source unit are very troublesome. 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 light source unit can be replaced and repaired without using a screwdriver or the like. work can be done. Therefore, work becomes easy.

Further, according to the present embodiment, since the metal fittings 320 are 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, it is possible to reduce the height of the lighting device 100 .

The base member 310 has a first base open end 310a and a second base open end 310b. The first base opening end 310a is an opening end opened in the first direction D1 (leftward direction), and the second base opening end 310b is an opening end opened in the second direction D2 (rightward 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 and constitutes the first base unit end portion 300a described with reference to FIG. Similarly, the second base closure member 330b has a second base closure portion 331b. The second base closing portion 331b closes the second base opening end 310b to constitute the second base unit end portion 300b described with reference to FIG.

More specifically, the first base closure member 330a has a first fitting portion 340a. The first fitting portion 340a extends in the second direction D2 (rightward) from the first base closing portion 331a. The first fitting portion 340a is housed in the inner space of the base member 310 from the first base opening end 310a. By housing the first fitting portion 340a in the inner space of the base member 310, the first base closing portion 331a is arranged at the first base opening end 310a to close the first base opening end 310a.

Similarly, the second base closure member 330b has a second insert 340b. The second fitting portion 340b extends in the first direction D1 (leftward direction) from the second base closing portion 331b. The second fitting portion 340b is accommodated in the inner space of the base member 310 from the second base opening end 310b.
