Description

この発明は、光源ユニットおよび照明器具に関する。例えば、光源ユニットと器具本体部を有する長尺形状の照明器具において、光源ユニットの器具本体部への取り付け構造に関する。 The present invention relates to a light source unit and a lighting fixture. For example, the present invention relates to a structure for attaching a light source unit to an instrument main body in a long lighting fixture having a light source unit and an instrument main body.

例えば、特許文献１には、長尺状に形成され光源と電源とを有する光源ユニット２と、この光源ユニット２が着脱自在に取り付けられる器具本体１とを備えた照明器具Ａの開示がある。この長尺状の光源ユニット２は、光源ユニット２の長手側方のうち一方に延出するように配設された爪部である係止部２６１（係止金具２６）と、係止部２６１が延出する側方とは反対の長手側方に配設され器具本体１に係止し引き上げられる係止ばね２８とを備えている。光源ユニット２は、係止部２６１と係止ばね２８とにより器具本体１に取り付けられる。 For example, Patent Literature 1 discloses a lighting fixture A including a light source unit 2 that is formed in a long shape and includes a light source and a power source, and a fixture body 1 to which the light source unit 2 is detachably attached. The long light source unit 2 includes a locking portion 261 (locking metal fitting 26) that is a claw portion disposed so as to extend to one of the longitudinal sides of the light source unit 2, and a locking portion 261. And a locking spring 28 which is disposed on the longitudinal side opposite to the side from which the rod extends and is locked to the instrument body 1 and pulled up.

しかし、特許文献１に記載の光源ユニット２は、係止部２６１が器具本体１の幅方向に納まるようにスライド機構を備えているが、スライドをさせる為に光源ユニット２では係止部２６１（係止金具２６）の一部しか保持していない構造である。
このため、光源ユニット２の自重のため、係止部２６１（係止金具２６）の取付構造に起因する隙間の積み重ねに伴う自重方向への変位の発生や、係止部２６１の弾性変形の発生により、光源ユニット２が自重方向に下がってしまうおそれがある。この場合、係止部２６１の側方近辺における光源ユニット２と器具本体１との間に隙間ができてしまう。 However, although the light source unit 2 described in Patent Document 1 includes a slide mechanism so that the locking portion 261 fits in the width direction of the instrument body 1, the light source unit 2 has a locking portion 261 ( It is a structure that holds only a part of the locking metal fitting 26).
For this reason, due to the weight of the light source unit 2, occurrence of displacement in the direction of its own weight due to stacking of gaps due to the mounting structure of the locking portion 261 (locking metal fitting 26) and occurrence of elastic deformation of the locking portion 261. Therefore, the light source unit 2 may be lowered in the direction of its own weight. In this case, a gap is formed between the light source unit 2 and the instrument body 1 near the side of the locking portion 261.

本発明は、光源ユニットと器具本体との間に隙間ができるのを抑制する構成の提供を目的とする。 An object of this invention is to provide the structure which suppresses that a clearance gap is produced between a light source unit and an instrument main body.
