したがって、開口部7を設けているので、電源装置2の熱は対流により開口部7から上昇し、LED5へ伝わりにくくなる。よって、LED5の温度上昇を避けられ、LED5の光出力を高くすることができる。   Therefore, since the opening 7 is provided, the heat of the power supply device 2 rises from the opening 7 due to convection and is not easily transmitted to the LED 5. Therefore, the temperature rise of LED5 can be avoided and the light output of LED5 can be made high.

図8、9は、本願請求項1〜4、6、7に対応した第四の実施形態である照明装置を示している。   8 and 9 show an illuminating device according to a fourth embodiment corresponding to claims 1 to 4, 6 and 7 of the present application.

なお、ここでは、上記第三の実施形態と相違する事項についてのみ説明し、その他の事項(構成、作用効果等)については、上記第三の実施形態と同様であるのでその説明を省略する。   Here, only matters different from those of the third embodiment will be described, and other matters (configuration, operational effects, and the like) are the same as those of the third embodiment, and the description thereof will be omitted.

本実施形態の照明装置は、開口部7の器具本体側口縁に垂下板8を設けている。具体的には、図8、9に示すように、アーム部3の器具本体内側端部と電源装置2の間の中程の部分に短手方向に長い矩形状の開口部7を設けている。そして、この開口部7の器具本体側口縁に下方に延びる垂下板8を設けている。   The lighting device of the present embodiment is provided with a hanging plate 8 at the opening of the opening 7 on the side of the instrument body. Specifically, as shown in FIGS. 8 and 9, a rectangular opening 7 that is long in the lateral direction is provided in a middle portion between the inner end of the instrument body of the arm portion 3 and the power supply device 2. . A hanging plate 8 extending downward is provided at the opening of the opening 7 on the instrument body side.

したがって、開口部7の器具本体側口縁に垂下板8を設けているので、電源装置2の熱は垂下板8に妨げられることにより、更に対流により開口部7から上昇することになり、LED5へ伝わりにくくなる。よって、LED5の温度上昇を避けられ、LED5の光出力を高くすることができる。   Therefore, since the drooping plate 8 is provided at the edge of the instrument body side of the opening 7, the heat of the power supply device 2 is hindered by the drooping plate 8 and further rises from the opening 7 by convection, and the LED 5 It becomes difficult to be transmitted to. Therefore, the temperature rise of LED5 can be avoided and the light output of LED5 can be made high.
