Abstract

PROBLEM TO BE SOLVED: To make it easy to carry out maintenance and inspection of a luminaire and to change a light source and prevent electric parts from being affected by thermal effects from a light source by installing a plate-like supporting body and a partitioning plate inside a luminaire main body. SOLUTION: A plate-like supporting body 2 to be supported in the inside of a luminaire main body 1 is constituted of a projected part 3 near the center part in the longitudinal direction and the projected part 3 has flat parts 4 in both ends. A recessed part 5 is formed in the upper face center of the inside of the supporting body 2 in the vertical direction by the projected part 3. A partitioning plate 6 installed in the inner end part of the supporting body 2 is so installed as to constitute an electric parts-housing chamber 7 and a light source housing chamber 8. With this structure, by detaching the supporting body 2, maintenance and inspection work for the luminaire can be made easily and attributed to the partitioning plate 6, electric members are protected from being affected by thermal bad effects of the light source 10 and furthermore due to the recessed part 5 formed in the upper face center of the inside of the supporting body 2, heat convection current is generated and the temperature rise in the recessed part 5 can be suppressed and consequently, bad effects of intense heat on electric parts can be avoided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in lighting equipment.

[0002]

2. Description of the Related Art Lighting equipment used on roads, sidewalks, and the like generally comprises an electrical component storage room for storing electrical components such as ballasts and condensers, and a light source storage room for arranging light sources. The configuration is such that the electrical components are not thermally affected by the high heat of the light source. The electric components are individually supported in the electric component storage room.

[0003]

The maintenance and inspection of lighting equipment used on roads and sidewalks and the replacement of light sources are often performed at high altitudes. However, in the above-mentioned lighting equipment, electric components are individually provided. There is a drawback that the work is difficult because it is configured so as to be supported in a dynamic manner. Further, there is a disadvantage that the electric components are adversely affected by heat from the light source. Furthermore, some types of lighting fixtures have a structure that requires a down transformer to be used when used in a place where the voltage is different.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and makes it possible to easily perform maintenance and inspection of lighting equipment and replacement work of a light source, and also to prevent electric parts from being adversely affected by heat from the light source. It is another object of the present invention to provide a lighting fixture that can be adapted to a plurality of models.

Means for Solving the Problems The present invention has the following structure to solve the above-mentioned problems. In other words, the invention described in claim 1 relates to a lighting device having a light source mounted inside a lighting device main body having a bottom opening and a reflector for controlling light distribution of the light source. And it has a protruding part near the center in the longitudinal direction of the plate-shaped support body supported inside the lighting fixture main body,
The protruding portion has flat portions at both ends. In addition, a partition plate is arranged at an end of the plate-shaped support on the light source side to form an electric component storage room and a light source storage room, an electric component unit is fixed in the electric component storage room, and a light source is provided on the light source storage room side. Is provided with a socket for mounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lighting fixture according to the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes a front opening type lighting fixture main body, and 2 denotes a plate-shaped support body that is supported inside the lighting fixture main body 1 and has a protruding portion 3 near a center in a longitudinal direction. The protruding portion 3 has flat portions 4 at both ends. The protruding portion 3 forms a concave groove 5 in the vertical direction at the center of the inner upper surface of the plate-shaped support.

Reference numeral 6 denotes a partition plate provided at the inner end of the plate-like support member.
A light source storage room 8 is configured. Reference numeral 9 denotes a socket disposed on the light source storage chamber 8 side of the partition plate 6, and reference numeral 10 denotes a light source mounted on the socket 9, which is constituted by using, for example, a 40-watt high-pressure sodium lamp.

Reference numeral 11 denotes a reflector supporting member fixed to the light source storage chamber 8, which is made of, for example, steel. Reference numeral 12 denotes an upper reflector supported by the reflector support 11, which is arranged above the light source. Also, the upper reflector 12
Is made of an aluminum material having a protrusion toward the center in the longitudinal direction of the light source, and the entire surface is configured as a diffusion surface. The inclination angle inside the upper reflector 6 is, for example, 15
It is configured at 0 degrees. Reference numeral 13 denotes a parabolic reflector supported by the reflector support 11, which is arranged symmetrically on both sides of the light source. In addition, the entire surface is configured as a diffusion surface. When the surface of the parabolic reflector 7 is configured as a diffusion surface, glare can be reduced. Reference numeral 14 denotes a rear reflector disposed at the back of the light source, which is made of an aluminum material and whose entire surface is formed as a diffusion surface.

The distance between the light source 10 and the upper reflector 12 is
For example, the light source 10 and the parabolic reflector 1 are configured as narrow as 6 mm.
The interval of 3 is configured to be as narrow as 40 mm, for example, so that the luminaire is reduced in size as a whole.

The reflector support 11 has a plurality of pairs of support holes 15 and 16 spaced from each other in the longitudinal direction. When light sources having different lengths are mounted, the reflector support 11 moves back and forth. Thereby, the reflector is configured to be located at a predetermined position with respect to the light source.

Reference numeral 18 denotes a light-transmitting glove which can be opened and closed on the lighting fixture body, and is made of, for example, an acrylic material. Reference numeral 18 denotes an electrical component support housed and arranged in the electrical component housing section, which is made of, for example, steel. 19
Is a step-down transformer supported on an electric component support, 20 is a ballast, 21 is a capacitor, and 22 is an automatic blinker.

[0012]

According to the present invention described above, the maintenance work of the luminaire can be easily performed by removing the plate-like support, and the partition plate causes the electric parts to be adversely affected by the heat from the light source. In addition, a concave groove formed in the center of the upper surface of the inner surface of the plate-shaped support generates heat convection and suppresses the temperature rise in the same part, so that the electric parts are not adversely affected by high heat. It has a great effect. Further, since all surfaces of the upper reflector, the parabolic reflector, and the rear reflector are configured as diffusion surfaces, there is a special effect that reflected light can be effectively used.
