DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture has the light source 1 and the fixture main body 2.

The light source 1 uses a lamp of a type having a reflecting surface on the half of the light source light emitting portion on the socket side. The device main body 2 has a substantially cylindrical shape having a lower surface opening 2a that covers the light source 1, is translucent, and has a thin, substantially annular light emitting portion 5 that emits light by a light guiding effect at a peripheral portion of the lower surface opening. In the embodiment, the light source 1 emits light from the light source 1, which is a fixture body of a recessed lighting fixture attached to the recess 3 provided in the ceiling surface 6, which is formed of a resin material, such as polycarbonate, in a substantially cylindrical shape. A plurality of, for example, four substantially columnar portions 4 are formed above the position of the portion. Make In addition, the outer peripheral surface of the instrument body 2 is subjected to reflection surface processing by, for example, aluminum vapor deposition plating or painting. However, the light emitting unit 5
At least, the lower surface and the peripheral side surface of the light emitting unit 5 are excluded from the reflection surface processing. A metal ceiling plate 7 is attached to the upper end of the substantially columnar portion 4 of the appliance body 2 by a fixture, and the lamp socket 8 is penetrated and attached to the ceiling plate 7. The light source 1 is detachably mounted on the lamp socket 8.

Reference numeral 9 denotes a substantially L-shaped mounting spring whose base end is attached to the instrument body 2 by a fixture 12 and whose distal end is located at the edge of the embedding hole 3 of the ceiling material 10 forming the ceiling surface 6. Lock. Reference numeral 11 denotes a wire insertion hole for a quick connection terminal of the lamp socket 8.

When the instrument body 2 is mounted on the ceiling, the mounting body 9 is elastically deformed so that the tip of the mounting spring 9 enters the embedding hole 3 and the instrument body 2 is inserted into the embedding hole 3, and the frame that becomes the light emitting section 5 is formed. The fixture is locked to the ceiling surface 6 and the mounting spring 9 is locked to the hole edge of the embedding hole 3, and the tool main body 2 is mounted to the ceiling material 10. Light source 1
When is turned on, light is received on the inner surface of the appliance body 2 and light is transmitted to and guided to the front end of the frame-shaped portion by the light-guiding action of the appliance body 2, so that the light-emitting portion appears on the lower surface of the ceiling surface 6. 5 is caused to emit light.

Therefore, according to the first embodiment,
The light emitting portion 5 of the translucent instrument main body 2 can obtain an eye catching effect while obtaining a relatively narrowed light distribution by the lower surface opening 2a. Since the lower surface of the frame is illuminated by the light emitting unit 5, a function that cannot be achieved by the conventional open type, that is, a reduction in glare of the appliance can be achieved. Further, the inside of the ceiling can be illuminated through the appliance body 2, which is convenient for cleaning the inside of the ceiling.

Since the outer peripheral surface of the fixture main body 2 is subjected to the reflection surface processing, the light guide effect of the fixture main body 2 can be increased and the effect of the reflector can be obtained, so that light leakage to the outside such as the ceiling can be prevented. be able to. By changing the position of the reflection surface processing such as the aluminum vapor-deposited surface, a change in the eye catch effect can be obtained, and the number of parts is small and inexpensive as compared with a lighting fixture aiming at the eye catch effect.

Further, since the device main body 2 has a plurality of substantially columnar portions 4 formed above the light emitting portion 5 of the light source 1,
The gap between the substantially columnar portions 4 of the device main body 2 enables heat dissipation and material saving. Further, a metal top plate 7 is attached to the upper end of the substantially columnar portion 4 of the appliance body 2, and the lamp socket 8 is attached to the top plate 7, so that the lamp socket 8 can be attached with a simple configuration. In addition, it is easy for the instrument body 2 to respond to the heat of the light source 1.

A second embodiment of the present invention will be described with reference to FIG. That is, in the lighting fixture, in the first embodiment, the light source 1 uses a general lamp, and the fixture main body 2 is formed so that the upper part of the light source light emitting portion 1a of the fixture main body 2 forms a reflection surface. ing. That is, the upper wall portion 2b is formed at the base side of the substantially columnar portion 4 of the instrument main body 2, the small hole 14 that can penetrate only the socket side neck portion 1b of the light source 1 is formed, and the upper wall portion 2b is connected to the reflecting surface of the light source 1. And that. A reflective surface such as plating may be formed on the upper wall 2b.

According to the second embodiment, the light can be reflected downward by the upper wall portion 2b, so that the light can be effectively used. Thus, a lighting device excellent in light distribution on the lower surface can be obtained, and an eye catch effect can be obtained.

The other points are the same as in the first embodiment.

A third embodiment of the present invention will be described with reference to FIG. That is, in this lighting fixture, in the second embodiment, the lower part of the inner surface of the fixture main body 2 is subjected to light shielding. That is, by performing light-shielding processing by vapor deposition plating, painting, or the like on the range A extending from the inner surface intermediate position near the lower surface opening of the appliance body 2 to the lower surface of the frame-shaped portion as the light-emitting portion 5, the light-shielding effect of suppressing glare can be obtained. While obtaining, only the end surface of the frame-shaped portion serves as the light emitting portion 5 as shown by the arrow, and light can be emitted therefrom, so that an eye catch effect can be obtained. Also, by changing the position of vapor deposition plating or painting, the amount and appearance of light can be changed, and the change in light can be enjoyed.
