BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention will be described based on matters unique to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

In the illustrated embodiment, a fluorescent lamp 2 is provided on a lower surface of a main body 1 and an incandescent lamp 3 is provided on an upper surface of the main body 1. And an incandescent lamp 3 is provided on the outer surface of the sub-main body 4, and a reflector 6 serving as a partition between the incandescent lamp 3 and the ceiling 5 is attached to the upper surface of the sub-main body 4.

In the illustrated embodiment, a fluorescent lamp 2 is provided on the lower surface of the main body 1 and an incandescent lamp 3 is provided on the upper surface of the main body 1. This is a lighting device in which an inverted U-shaped sub-main body 4 is provided and an incandescent lamp 3 is provided on an outer surface of the sub-main body 4. Then, a metal fitting 7 having a substantially inverted U-shaped cross section for attaching the main body 1 to the ceiling 5 is fixed to the upper surface of the main body 1 so as to be located in the sub-main body 4, and the metal fitting 7 is attached to the ceiling 5 in the center of the main body 1. An operation opening 8 for attachment is formed. Also, the sub-body 4
A groove 9 that opens downward is formed in the outer periphery of the cable, and a wiring cord 11 that connects a plurality of sockets 10 to which a plurality of incandescent lamps 3 are mounted is passed through the groove 9.

A hanging rosette 12 and a mounting bracket 13 surrounding the hanging rosette 12 are fixed to the ceiling 5, and the mounting 7 is fixed to the mounting bracket 13 by screws 14. The center of the upper surface of the metal fitting 7 is opened to allow the hanging rosette 12 to pass therethrough. Secondary body 4
Is also opened to allow the hook-up rosette 12 and the mounting bracket 13 to pass through. A power supply cord 15 is led out of the main body 1, and a hook plug 16 electrically connected to the hooking rosette 12 is provided at a tip of the power cord 15. The lower end of the bracket 7 is the body 1
Is fixed with screws 17 on the upper surface. A globe 18 covering the fluorescent lamp 2 is detachably attached to the lower surface of the main body 1 by appropriate means.

A light shielding plate 19 for controlling the light distribution of the incandescent lamp 3 is attached to the outer periphery of the upper surface of the main body 1. Secondary body 4
Is a boss 20 made of synthetic resin and integrally formed in the groove 9.
Having. The sub-main body 4 is fixed to the upper surface of the main body 1 by screwing a screw (not shown) passed through the main body 1 to the lower surface of the boss 20. A lighting circuit (not shown) in the main body 1 is first wired to a specific socket 10, and the above-mentioned wiring cord 11 is sequentially sent from that socket 10 to an adjacent socket 10 and wired. The socket 10 is attached via a fixture 21 fixed in the groove 9 and is exposed from a notch 22 formed on the outer wall of the groove 9.

[0010] There are two types of reflecting plates 6, and FIG.
-Fig. 4 is a thin metal plate, Fig. 2-Fig. 3 (B)-
5 is made of a resin having a large plate thickness. A step 23 is formed on the upper surface of the sub-main body 4 so that the outside becomes higher, and a mounting piece 23 having an opening on one side is formed on the outside, and FIG. 1 to FIG.
When the reflector 6 shown in FIG. 4 is mounted, the notch 24 facing the central opening is aligned with the mounting piece 23 and then rotated, and the locked piece 25 which is located on the side of the notch 24 and protrudes relatively inwardly is provided. Into the lower surface of the mounting piece 23. At this time, the locked piece 25 is aligned and inserted into a relatively small vertical width inside the mounting piece 23. When attaching the reflector 6 shown in FIGS. 2 to 3B to FIG. 5, the notch 2 facing the central opening is used.
4 is rotated after aligning the mounting piece 23 with the mounting piece 23, and the locked piece 25 which is located on the side of the notch 24 and protrudes relatively small inward.
Into the lower surface of the mounting piece 23. At this time, the locked piece 2
Reference numeral 5 is inserted into the outside of the mounting piece 23 in a relatively large vertical width. In this manner, the reflectors 6 having different thicknesses can be attached without rattling.

According to the present embodiment, the sub-main body 4 having an outer diameter smaller than that of the main body 1 is provided on the upper surface of the main body 1, and the incandescent lamp 3 is provided on the outer surface of the sub-main body 4. Since the reflection plate 6 also serving as a partition is mounted on the upper surface of the sub-main body 6, a rise in the temperature of the ceiling 5 can be significantly reduced.
Can be prevented from being discolored or the cross-pasting of the ceiling 5 can be discolored. Further, on the upper surface of the main body 1 is provided a sub-main body 4 having a substantially inverted U-shaped cross section with a smaller outer diameter than the main body 1.
Since the incandescent lamp 3 is provided on the outer surface of the incandescent lamp 3, there is little possibility that the incandescent lamp 3 will be damaged by careless handling such as when mounting on a ceiling. Further, a metal fitting 7 having a substantially inverted U-shaped cross section for attaching the main body 1 to the ceiling 5 is positioned so as to be located in the sub main body 4.
And the metal fitting 7 is mounted on the ceiling 5 in the center of the main body 1.
Because the operation opening 8 for attaching to the
It can be easily mounted on the ceiling 5. In addition, a groove 9 that opens downward is formed on the outer periphery of the sub-main body 4, and a wiring cord 11 that connects a plurality of sockets 10 to which a plurality of incandescent lamps 3 are mounted is passed through the groove 9. The processing of the code 11 can be performed with good appearance.
