本発明は、照明器具、詳しくは反射板の接地構造に関するものである。   The present invention relates to a lighting fixture, and more particularly to a grounding structure for a reflector.

一面を開放した浅い箱状の照明器具本体内に、例えば複数本の直管状の蛍光放電灯を並列に装着し、屋内の天井や壁面などに敷設する照明器具は普通に知られている。図５（平面図）および図６（図５のＡ−Ａ断面図）はこのような照明器具の一例の構成を示すもので、図５および図６において、１は鉄などの金属製の照明器具本体、２は鉄などの金属製の反射板、３は点灯回路部品、４は電線、５は直管型放電灯などの光源灯、６はソケットである。照明器具本体１は表面全域に絶縁塗膜（内面は白色塗膜）を施した長方形の浅い箱状をなし、長手方向の側面は開放側に広がる傾斜面１ａとされ、底面１ｂの中央部に長手方向に伸びる、適宜間隔を隔てた２本の断面三角形状の突条１ｃが開放側に向けて形成されている。   A lighting fixture in which a plurality of straight tubular fluorescent discharge lamps are mounted in parallel in a shallow box-shaped lighting fixture main body with one surface open and laid on an indoor ceiling or wall surface is generally known. 5 (plan view) and FIG. 6 (AA cross-sectional view of FIG. 5) show an example of the structure of such a lighting fixture. In FIGS. 5 and 6, 1 is an illumination made of metal such as iron. An instrument body, 2 is a reflector made of metal such as iron, 3 is a lighting circuit component, 4 is an electric wire, 5 is a light source lamp such as a straight tube discharge lamp, and 6 is a socket. The luminaire body 1 has a rectangular shallow box shape with an insulating coating (the inner surface is a white coating) on the entire surface, and the side surface in the longitudinal direction is an inclined surface 1a that extends to the open side. Two ridges 1c having a triangular cross section extending in the longitudinal direction and having an appropriate interval are formed toward the open side.

反射板２は表面全域に絶縁塗膜（外面は白色塗膜）が施され、照明器具本体１の底面１ｂ側に広がる断面三角形状をなし、広げた両側の端部２ａは内側に折り曲げて形成され、その両側の端部２ａを照明器具本体１の２本の三角形状の突条１ｃに反射板２のばね力に抗して嵌め込んで照明器具本体１に固定される。ソケット６は照明器具本体１の三角形状の突条１ｃと側面間の底面１ｂに沿う長手方向両側の端部に設けられ、光源灯はこのソケット６に装着される。点灯回路部品３は照明器具本体１の２本の断面三角形状の突条１ｃ間の底面１ｂに取付けられ、点灯回路部品３からソケット６などへ伸びる電線４は照明器具本体１の２本の断面三角形状の突条１ｃ間の底面１ｂに沿って配置されている。   The reflecting plate 2 has an insulating coating (a white coating on the outer surface) applied over the entire surface, has a triangular cross section that extends toward the bottom surface 1b of the lighting fixture body 1, and is formed by bending the expanded end portions 2a on both sides. Then, the end portions 2a on both sides thereof are fitted into the two triangular protrusions 1c of the luminaire main body 1 against the spring force of the reflector 2 and fixed to the luminaire main body 1. The socket 6 is provided at both ends in the longitudinal direction along the bottom surface 1 b between the triangular protrusion 1 c and the side surface of the lighting fixture body 1, and the light source lamp is attached to the socket 6.

以上のような照明器具は、屋内の天井や壁面などに敷設するとき、照明器具本体１は接地されるので、照明器具本体１に触れても感電する恐れはないが、照明器具本体１と反射板２との間は絶縁塗膜により絶縁されており、電線４が反射板２上に垂れ下がった場合には反射板２の電位を高め、反射板２に触れると感電する恐れがあるといった問題があった。   When such a lighting fixture is laid on an indoor ceiling or wall surface, the lighting fixture main body 1 is grounded, so there is no fear of electric shock even if the lighting fixture main body 1 is touched. The plate 2 is insulated by an insulating coating film. When the electric wire 4 hangs down on the reflection plate 2, the potential of the reflection plate 2 is increased. there were.

本発明が解決しようとする課題は、複数の光源灯の間に配置され、両側の光源灯の光をそれぞれ反射する反射板を前記照明器具本体に固定してなる照明器具において、簡単な構造によって反射板と照明器具本体とを常に同電位とし、斯かる問題を解消する点にある。   The problem to be solved by the present invention is a lighting fixture that is arranged between a plurality of light source lamps and that has reflectors that respectively reflect the light of the light source lamps on both sides fixed to the lighting fixture body. The reflector plate and the luminaire main body are always set to the same potential, and the problem is solved.

本発明は、一面側に複数の光源灯を装着し、光源灯間の中央部に前記光源灯の点灯回路部品を取付けてなる全面に絶縁塗膜を施した金属製の照明器具本体と、前記点灯回路部品を覆い前記照明器具本体に装着した複数の光源灯の間に配置され、両側の光源灯の光を反射する全面に絶縁塗膜を施した金属製の反射板とを備え、前記反射板を前記照明器具本体の前記一面側に固定してなる照明器具において、先端に突起を備えた接地用ばね金具を前記照明器具本体に取付けるとともに、前記反射板を前記照明器具本体に固定すると同時に、前記接地用ばね金具の突起により前記反射板の絶縁塗膜を剥離して前記接地用ばね金具と前記反射板を導電接続してなることを特徴とする。   The present invention is a metal luminaire body having a plurality of light source lamps mounted on one side and an insulating coating applied to the entire surface of the light source lamp lighting circuit component attached to the center between the light source lamps, A reflective plate made of metal that covers the lighting circuit components and is disposed between the plurality of light source lamps mounted on the luminaire main body and reflects the light of the light source lamps on both sides with an insulating coating film on the entire surface, and In a lighting fixture in which a plate is fixed to the one surface side of the lighting fixture main body, a grounding spring metal fitting having a protrusion at a tip is attached to the lighting fixture main body, and at the same time the reflector is fixed to the lighting fixture main body. The insulating coating film of the reflecting plate is peeled off by the projection of the grounding spring metal fitting, and the grounding spring metal fitting and the reflecting plate are conductively connected.

本発明に係る照明器具では、先端に突起を備えた接地用ばね金具を照明器具本体にねじなどで導電接続して取付け、反射板をこの接地用ばね金具のばね力に抗し、突起で絶縁塗膜を剥離しながら照明器具本体に固定するので、接地用ばね金具を照明器具本体に取付けるという簡単な作業構造で固定後は反射板と照明器具本体は常に同電位（接地電位）を維持することができ、反射板に触れても感電する恐れがなく、安全性の高い照明器具を得ることができる。   In the luminaire according to the present invention, a grounding spring metal fitting having a protrusion at the tip is attached to the luminaire main body by conducting a conductive connection with a screw or the like, and the reflector is resisted by the spring force of the grounding spring metal fitting and insulated by the protrusion. Since it is fixed to the luminaire main body while peeling the coating film, the reflector and the luminaire main body always maintain the same potential (grounding potential) after fixing with the simple work structure of attaching the grounding spring metal fitting to the luminaire main body. Therefore, there is no fear of electric shock even when the reflector is touched, and a highly safe lighting apparatus can be obtained.

複数の光源灯の間に配置され、両側の光源灯の光をそれぞれ反射する反射板を前記照明器具本体に固定してなる照明器具において、簡単な構造によって反射板と照明器具本体とを常に同電位とする目的を、照明器具本体に接地用ばね金具を取付けることにより実現した。   In a luminaire that is disposed between a plurality of light source lamps and has a reflector that reflects light from the light sources on both sides fixed to the luminaire main body, the reflector and the luminaire main body are always the same with a simple structure. The purpose of the electric potential was realized by attaching a grounding spring metal fitting to the lighting fixture body.
