Description

[Detailed explanation of the idea] 〔Technical field〕 The present invention relates to a recessed lighting fixture.

[Background technology]

As awareness of energy conservation increases, there is an increasing number of cases in which insulation is installed in the ceiling to improve efficiency during winter heating, especially in cold regions. Among various insulation methods, the plowing method, in which small pieces of insulation material are blown in, can be applied to every nook and cranny. Lighting equipment is also covered with insulation material, and if the light source is an incandescent lamp or other lighting equipment that generates a lot of heat, the temperature of the lighting equipment body made of sheet metal such as steel plate covered with insulation material will rise abnormally, and it may be left in that state for a long time. In the worst case scenario, if used, the construction materials in contact with the outer surface of the sheet metal lighting fixture body could become carbonized, leading to low-temperature ignition, which could pose a safety hazard.

[Purpose of invention]

The object of the present invention is to provide a safe recessed lighting fixture that does not cause the temperature of the outside surface of the lighting fixture to rise abnormally even if it is covered with a heat insulating material during attic insulation construction.

[Disclosure of the invention] The present invention prevents an abnormal temperature rise on the outer surface of the lighting equipment body by blocking heat from the light source in recessed lighting equipment such as downlights. Description will be made based on the embodiment shown in the figures.

The lighting fixture main body 1 has a cylindrical shape with a closed upper surface and an open lower end with an outer flange at the lower end, and the inner surface is provided with a plurality of mounting holes 2 through which mounting screws are inserted. It is attached with an outer flange in contact with the surface, and a heat insulating material 4 is fixed to the outer surface and upper surface of the sheet metal body 3 so as to have a thickness of at least five times the thickness of the sheet metal body 3. A socket 5 is attached to the approximate center of the inner surface of the upper surface of the lighting fixture main body 1, and an incandescent light bulb 6 is attached thereto as a light source lamp. The reflector plate 7 is formed of a thin aluminum plate so as to cover the incandescent light bulb 6, and its inner surface is a reflective surface. The reflector mounting frame 8 is formed into an annular shape with a U-shaped cross section, and frame mounting springs 9 are attached to two centrally symmetrical locations, and is suspended from the lighting fixture main body 1 while being pulled up by the frame mounting springs 9. The reflecting plate 7 is mounted with its outer peripheral rising end surface in contact with the ceiling surface.

In this recessed lighting fixture, the reflector plate 7 reflects heat as well as light, and the outer surface of the lighting fixture body 1 is formed with a heat insulating material 4, so that the surface temperature of the lighting fixture body 1 can be lowered, and it can be used as a construction material. are in contact with the heat insulating material 4, so even if the light fixture body 1 is covered with heat insulating material during attic insulation construction, the outside surface of the light fixture body 1 will not experience an abnormal temperature rise, and there is no risk of carbonization of construction materials, making it safe. be.

[Effects of the invention] According to the invention, the outer surface of the lighting fixture body is made of a heat insulating material, and the heat generated by the light source lamp and transmitted from the outside surface of the lighting fixture body to the ceiling can be blocked by the lighting fixture body. Even if the lighting fixture body is covered with insulation material during installation of attic insulation, the temperature of the outside surface of the lighting fixture body will not rise abnormally, and the temperature of the construction material will be lowered because it comes into contact with the construction material through the insulation material on the outside of the lighting fixture body. There is no risk of carbonization of construction materials.
