Abstract
【解決手段】略中央部に開口12を有する器具本体1と、略円筒状に形成され、前記器具本体1の開口12に取付けられる取付部4としてのアダプタガイドと、複数の発光素子22が実装され、前記器具本体1の開口12を囲むように前記器具本体1に配設された基板21と、前記アダプタガイドの外周側と前記器具本体における開口周囲の凹部11とにより形成された空間に配置され、前記複数の発光素子22を点灯制御する点灯装置3とを具備する。
【選択図】図2
Description
このように、各列同数の発光素子22を実装するため、位置をずらせてバランスよく発光素子22を基板21上に分散配置することができる。
また、光源部から放射される光の均斉度を向上するため、発光素子に対応して拡散レンズを設けたり、カバー部材に光の透過率制御手段を設けたりしてもよい。
さらにまた、発光素子は、LEDや有機EL等の固体発光素子が適用でき、この場合、発光素子の個数、列数は、特段限定されるものではない。
