Abstract

According to one embodiment, there is provided a luminaire including a light source module, a power supply device, and a luminaire main body. The light source module includes a board, a light source provided on the board, a supporting body supporting the board, and a light transmissive cover covering the board and has a long shape. The power supply device supplies electric power to the light source module. The luminaire main body is provided with the light source module and the power supply device and has a long shape. The luminaire main body includes a pair of reflecting plate sections and a housing section provided between the pair of reflecting plate sections and housing at least a part of the power supply device. The light source module is provided in the luminaire main body with the supporting body and covers the housing section and the power supply device.

Claims

1. A luminaire comprising:

a long-shaped luminaire main body provided with the light source module and the power supply device,

the luminaire main body including a pair of reflecting plate sections and a housing section provided between the pair of reflecting plate sections and configured to house at least a part of the power supply device, and

the light source module being provided in the luminaire main body with the supporting body opposed to the housing section and covering the housing section and the power supply device.

2. The luminaire according to claim 1, wherein

the housing section includes a bottom plate section disposed to be parallel to the supporting body and a pair of side plate sections extending from both sides of the bottom plate section to the light source module,

at least a part of the power supply device is housed in a region surrounded by the bottom plate section and the pair of side plate sections, and

each of the pair of reflecting plate sections continues from an end side on an opposite side to the bottom plate section in the pair of side plate sections.

3. The luminaire according to claim 1, wherein

the light source module is provided such that at least a part of the cover is located between the pair of reflecting plate sections,

the cover includes an inclining section inclining to expand from the board in an emitting direction of light of the light source, and

the inclining section and at least a part of the pair of reflecting plate sections are provided to be opposed to each other.

4. The luminaire according to claim 3, wherein the pair of reflecting plate sections inclines in a direction same as the inclining direction in the inclining section of the light source module.

5. The luminaire according to claim 2, wherein

the luminaire main body further includes a pair of first end plates respectively attached to end portions in a longitudinal direction and closing the end portion of the housing section, and

the pair of first end plates can be attached to be variable in an up down direction according to an external dimension of at least one of the luminaire main body and the light source module.

6. The luminaire according to claim 5, wherein

the pair of first end plates include engaging sections configured to engage with sections to be engaged provided in the pair of side plate sections, and

arrangement positions of the engaging sections deviate from a center in a height direction of the first end plates.

7. The luminaire according to claim 5, wherein

each of the pair of first end plates includes a first projecting section and a second projecting section,

the first projecting section is provided at one end in a height direction and extends in the longitudinal direction to the region,

the second projecting section is provided at one other end in the height direction and extends in the longitudinal direction to the region, and

a length in the longitudinal direction of the first projecting section is different from a length in the longitudinal direction of the second projecting section.

8. The luminaire according to claim 7, wherein each of the pair of first end plates covers, with the first projecting section or the second projecting section, a gap formed between an end portion in the longitudinal direction of the housing section and the light source module.

9. The luminaire according to claim 7, wherein each of the pair of first end plates sets the first projecting section or the second projecting section in contact with an end portion in the longitudinal direction of the light source module and supports the end portion in the longitudinal direction of the light source module.
