Description

本発明は、長尺な蛍光ランプを用いる蛍光灯照明器具に関する。特に、ランプソケットや点灯装置を支持固定する器具本体と蛍光ランプからの光を有効的に反射させ前記内蔵部品を覆い意匠性を向上させる反射板との電気的接続を確保し、感電保護と雑音端子電圧などの雑音低減のを図るものである。 The present invention relates to a fluorescent lamp luminaire using a long fluorescent lamp. In particular, an electrical connection between the fixture body that supports and fixes the lamp socket and the lighting device and a reflector that effectively reflects the light from the fluorescent lamp and covers the built-in components to improve the design is ensured. This is intended to reduce noise such as terminal voltage.

一般に、器具本体と反射板とのアース接続は、この両者間に導電性材料を用いたアース金具等の別部品を追加取付けしてなされることが多い。 In general, the earth connection between the instrument body and the reflector is often made by additionally attaching another part such as a grounding metal member using a conductive material between the two.

前記技術においては、導電性材料を用いたアース金具等の別部品を追加取付けしているため、部品コストや部品取付けコストがアップするなど経済性の面に問題があった。本発明はこれを解決する。 In the above technique, since another part such as a grounding fitting using a conductive material is additionally attached, there has been a problem in terms of economy such as an increase in part cost and part attachment cost. The present invention solves this.

本発明においては、長尺な金属製の器具本体を備え、前記器具本体の両端部に装着される金属製のソケット台を備え、前記各ソケット台に装着されるランプソケットを備え、前記各ランプソケット間に装着される直管形の蛍光ランプを備え、前記器具本体・ソケット台の下方であって前記蛍光ランプの上方に装着される長尺な反射板を備え、前記反射板は塗装が施された塗装鋼板製であり、前記反射板は前記器具本体の長さ方向に沿った舟形であり、前記反射板の短手方向に沿った断面形状は複数の直線状の反射面部と該反射面部相互間の少なくとも一つの曲成部を具備する。
従来技術の課題を解決するため、前記ソケット台の一部にアース接続用の突起を１つ以上形成し、前記突起を前記反射板における前記曲成部ないしはその近傍に引張力が加わる方向で圧接し、前記圧接により前記突起を前記反射板における金属部分に電気的に接続する。好ましくは、前記アース接続用の突起を複数個設ける。この場合は反射板の短手方向にずれた時でも、確実な電気的接続が可能となる。In the present invention, a long metal instrument body is provided, a metal socket base attached to both ends of the instrument body, a lamp socket attached to each socket base, and each lamp A straight tube fluorescent lamp mounted between the sockets, and a long reflector mounted below the fixture body and socket base and above the fluorescent lamp, and the reflector is coated. The reflecting plate is a boat shape along the length direction of the instrument body, and the cross-sectional shape along the short direction of the reflecting plate is a plurality of linear reflecting surface portions and the reflecting surface portion. It has at least one bent portion between each other.
In order to solve the problems of the prior art, one or more ground connection protrusions are formed on a part of the socket base, and the protrusions are pressed in a direction in which a tensile force is applied to the bent portion of the reflector or in the vicinity thereof. The protrusion is electrically connected to the metal portion of the reflector by the press contact. Preferably, a plurality of projections for ground connection are provided. In this case, reliable electrical connection is possible even when the reflector is displaced in the short direction.

前記反射板は断面が略舟形であり、前記反射板の短手方向に沿った断面形状は複数の直線状の反射面部と該反射面部相互間の少なくとも一つの曲成部を具備しており、直線状の反射面の中で比較的強度の強い部分の曲成部ないしはその近傍に向け引張応力が加わるようにアース接続用の突起を構成としたことにより直線状の反射面の曲がりや変形を防止できる。
従来技術のように器具本体と反射板との電気的な接続のための導電性材料によるアース金具などの別部品を追加することなく、ソケット台の一部に反射板の曲成部に圧接する記突起を一体的に構成した為、安価で経済的な電気的接続が得られる。また、前記アース接続用の突起を複数個設けることにより反射板の短手方向にずれた時でも確実な電気的接続が可能となる電気的信頼性の高い構成が得られる。
さらに、点灯装置を囲む器具本体と反射板の電気的接続の連続性により、点灯装置から電源に乗るノイズ（雑音端子電圧）を低減する効果が期待できる。The reflecting plate is substantially boat-shaped in cross section, and the cross-sectional shape along the short direction of the reflecting plate includes a plurality of linear reflecting surface portions and at least one bent portion between the reflecting surface portions, By configuring the projection for ground connection so that tensile stress is applied toward or near the bent portion of the relatively strong portion of the straight reflecting surface, the bending or deformation of the straight reflecting surface can be prevented. Can be prevented.
Without adding a separate part such as a grounding fitting made of a conductive material for electrical connection between the fixture body and the reflector as in the prior art, it is pressed against the bent portion of the reflector on a part of the socket base. Since the projections are integrally formed, an inexpensive and economical electrical connection can be obtained. In addition, by providing a plurality of projections for ground connection, a configuration with high electrical reliability that enables reliable electrical connection even when the reflector is displaced in the short direction can be obtained.
Furthermore, the effect of reducing noise (noise terminal voltage) riding on the power source from the lighting device can be expected due to the continuity of the electrical connection between the fixture body surrounding the lighting device and the reflector.
