Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in lighting equipment, and particularly to a structure that can efficiently illuminate school classrooms, hospital rooms, gathering places, and the like.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, in school classrooms, hospital rooms, gathering halls, etc., the ceiling surface direction is also illuminated in addition to the irradiated surface to give a bright image to the entire room. For example, as shown in FIG. 4, a lighting fixture body 1, which houses electrical parts such as a ballast inside, is fixed to the ceiling of a building, and a lower surface of the lighting fixture body 1 has flat parts at both ends. A reflector 2 having a V-shaped cross section is supported, and a frame 3 is provided on the lighting equipment main body 1, and a frame 3 is provided on both sides of the frame 30 with a fixed interval between the reflector 2 and the light source 4. However, according to the same structure, the reflector 2 supported on the lighting fixture body 1 and the reflector plate 5 supported on the frame 3 have been implemented. The light illuminating the direction of the ceiling surface from the distance between is only the direct light from the light source 4, and the reflected light cannot be used effectively, and the reflected light from the flat part of the reflector 2 has a high proportion of returning to the light source 4. There is a drawback that the light reflected from the reflector 2 and reflected by the reflector plate 5 is large, and the light from the light source cannot be used effectively.

[Purpose of the invention]

The present invention has been invented in view of the above point KII, and is a lighting device that effectively utilizes light from a light source to brightly illuminate an entire room, and is suitable for illuminating classrooms in schools, hospitals in hospitals, gathering halls, etc. ◇ [Means for solving the problem] The present invention will be explained below with reference to FIGS. 1 to 3. In the figure, reference numeral 11 denotes the main body of the lighting device, which houses electrical components such as a ballast or a capacitor, and 12 denotes an apex 130 directed downward toward the center, with reflective surfaces 14 and 15 on both sides.
The upper reflector plate has an apex 13 and a light source 11C, which is supported by the lighting fixture main body 11. Reference numeral 16 indicates a socket mount provided on both sides of the illuminator body 11, 17 a socket supported by the socket mount 16, 18 a light source attached to the socket 1T, and 19.20 a reflective surface 21 on both sides of the apex.
22, has a certain gap 23f between it and the upper reflector 12, and is arranged and fixed on both the left and right sides of the light source 18 with the apex facing the center of the light source 18. A certain 024 is an outer frame for supporting the side reflector, and has a rolled-up end. Also, the same side reflectors 19, 2
The apex of 0 is located at the same position as the outer end of the upper reflector 12 or slightly inside, so that the direct light and reflected light from the light source 18 illuminate not only the lower part of the instrument body but also the upper sides of the instrument body. It is composed of:

Also, as shown in figure g1, the reflection surfaces [4, 15 on both sides of the upper reflector 12 reflect light l! It is configured so that the light is projected upward through the space 23 and not onto the side reflectors 19 and 20.

Further, as shown in FIG. 1, on the upper surface of the side reflector 19° 20, the reflected light near the apex is projected upward, and the reflected light that is moving away from the apex is projected outward from the leg and passes through the gap 23. It is configured to illuminate the ceiling surface. 25 is an end plate, and 26 is a side fixing plate.

Next, the assembly order of the lighting fixture having the above structure will be explained.

First, the upper reflector 12, the socket mounting base 16, and the socket 17 are supported on the lighting equipment main body 11, and the end plate 25 and
The side fixing plate 26 and the outer frame 24 that supports the side reflectors 19 and 20 are combined, and then the end plate 25 and the lighting fixture main body 1 are assembled.
1 and tighten with tightening screw 27 to complete the assembly.

〔Effect of the invention〕

As described above, the present invention provides reflective surfaces on both sides of one vertex,
The north upper reflector is placed with the apex facing the center of the light source, and reflective surfaces are placed on both sides of the apex. is located at the same position as the outer part of the upper reflector or slightly inside, and has side reflectors arranged on both the left and right sides of the light source, and the reflecting surfaces on both sides of the upper reflector allow the reflected light to pass upward through the gap. The upper reflective surface of the side reflector is configured so that the reflected light near the apex is projected upward, and as it reaches the apex, the reflected light is projected outward from the upper part. I! i5!
Since it is configured to illuminate the ceiling surface through the cabinet, it is possible to illuminate the ceiling surface as well as the irradiated surface below the device itself, giving a bright image to the entire room.
Ideal as lighting equipment for hospital rooms, gathering halls, etc.

Further, the reflected light from the reflective surfaces on both sides of the upper reflector is projected upward through the gap, and is not projected onto the side reflectors, making it possible to effectively utilize the reflected light.

In addition, the upper surface of the reflective surface of the side reflector is configured so that the reflected light near the apex is projected upward, and as it moves away from the apex, the reflected light is projected upward and outward, illuminating the ceiling surface through the gap. All of the reflected light from the rotating section is projected onto the ceiling surface, effectively illuminating the ceiling surface, which has great utility value.
