Lighting circuit parts such as
The socket 13 is disposed on the lower surface of the top plate of the instrument body 4, and a fixing plate 14 is formed integrally extending laterally from the top plate of the main body 4. Angle 16 whose upper end is fixed to the fixing plate 14 is provided on both sides of the fixing plate 14, and the upper surface of the ceiling plate 18 is brought into contact with a vertically perforated groove 16a of this angle 16, so that the fixture body 4 can be attached in a vertical motion. A flexible mounting bracket 17 is provided. The frame 15 located on the lower surface of the opening 19 of the ceiling plate 18 is fixed by caulking at the lower part of the angle 16 (section A in FIG. 5A). Further, the peripheral edge of a reflector 8 inserted from below comes into contact with the lower peripheral surface of the frame 15, and the reflector 8 is attached to the instrument main body 4 by an appropriate means such as a spring member. Incidentally, the lamp 7 is attached to and removed from the socket 13 by insertion or rotation.

え、放熱効果が大きくなるものである。 Next, the gist of the present invention will be explained. In FIG. 1, a ballast 11, a glow bulb 12, a socket 13, etc. are arranged in the rectangular appliance body 4 as described above, and an external power source is connected to the side of the appliance body 4. terminal block 20
is attached. Although the shape of the end of the instrument main body 4 is square, it may be formed into a circular shape. Additionally, a fixing plate 14 is provided with an angle 16, etc., and is integrally formed to extend from the top plate of the appliance body 4.
The tip is circular. This is the instrument body 4
The fixing plate 14 side is formed into a square shape in order to arrange electrical parts on the side, and the fixed plate 14 side is formed into a circular shape within a size that can smoothly fit into the circular opening 19 of the ceiling plate 18. Further, as shown in FIG. 6, the tip of the fixing plate 14 may be shaped with corners removed, or may be shaped into a small straight circle. The tip of the fixing plate 14 is located inside the peripheral edge of the reflecting plate 8. Therefore, the heat dissipation around the reflecting plate 8 can be carried out without the fixing plate 14 getting in the way so much, and the heat dissipation effect is increased.

である。 Therefore, the construction of this lighting equipment will be carried out as follows. That is, as shown in FIG. 7a, the rectangular instrument main body 4 is inserted from below through the maximum diameter part of the opening 19, and then the instrument main body 4 is inserted through a rotational movement using the instrument main body 4 side as a fulcrum. 4, and finally insert the circular part of the fixing plate 14 into the opening 19.
Insert it closer to the back of the ceiling. In this case, the fixed plate 14
Since both the opening 19 and the opening 19 are circular, the tip of the fixing plate 14 can be inserted smoothly.

果も大きいという利点を有するものである。[Effects of the invention] As mentioned above, the present invention is a recessed lighting fixture that is installed by being inserted from below into an opening formed in a ceiling board, and the fixture body located above the reflector plate. Since at least one end side of the top plate of the device is formed into a substantially circular shape, even if the portion of the top plate formed into a substantially circular shape of the main body of the device is later inserted into, for example, a circular opening, it is not necessary to insert the top plate into a circular opening. The corner of the top plate of the device body can be inserted smoothly without hitting the edge of the opening, and has the advantage of being easy to install. By forming one end side into a substantially circular shape, the hot air rising from around the reflector is less likely to be obstructed by the top plate, and has the advantage that the heat dissipation effect is large.
