Traditionally, recessed downlight lighting fixtures include:
As shown in Fig. 1, a socket 2 is attached to the upper surface of a substantially cylindrical main body 1 having an outer flange at the lower end, and a fitting 3 is protruded from the side of the main body 1 and inserted into a mounting hole provided on the ceiling surface. It is well known that the ceiling material is clamped and mounted between the outer flange and the fixture 3. However,
When using such an embedded downlight lighting fixture in a cold region such as Hokkaido, if you spray insulating material after installing the fixture, the heat dissipation hole 4 to prevent the temperature rise inside the main body 1 will be removed. There is a risk of accidents such as insulation getting inside and accumulating inside, reducing lighting performance, recessed downlight lighting equipment becoming deformed due to abnormal temperature rise, and especially if the insulation is made of flammable material, there is a risk of accidents such as fire. and therefore,
As shown in FIG.
was installed, and then the insulation material 6 was sprayed on, which was time-consuming, had poor workability, and increased costs.

The purpose of the present invention is to make it possible to spray heat insulating material onto a recessed downlight lighting fixture without requiring any special members.
本考案を第３図及び第４図に示す実施例に基づ

The present invention will be explained based on the embodiment shown in FIGS. 3 and 4.

している。 The main body 1 has an outer flange 7 at the lower end and is closed at the upper end with a top plate 8 to form a substantially cylindrical shape with a bottom. A soluble thin film 10 is provided on the outer surface to cover the front heat radiation hole 9 and to be fused by heat. Inside the main body 1, an incandescent light bulb 12 is attached to the lower surface of the top plate 8 via a socket base 11. Main body 1
is inserted into a mounting hole provided on a mounting surface such as a ceiling surface, and the ceiling material is held between the mounting tool 3 provided on the side wall of the main body so as to be movable up and down and the outer flange 7 of the main body 1 and fixed to the mounting surface. has been done. The light diffusion panel 13 made of a milky white acrylic plate or the like is equipped with a spring (not shown).
It is placed on a ring-shaped frame 14 with an inner flange suspended from the inside of the main body 1, and closes the opening on the lower surface of the main body 1.

いずに断熱材吹きつけ施工に対応できる。 When this embedded downlight lighting equipment is used, the heat from the incandescent light bulb melts the soluble thin film and opens the heat radiation hole 9, so even when spraying insulation material, the light will turn on after the insulation material is installed. This eliminates the risk of the heat insulating material entering into the main body 1 and interfering with lighting, and it is possible to perform spraying construction of the heat insulating material without using any special members.
