Description
請求項6に記載の照明器具は、ソケットを有する器具本体と;この器具本体のソケットに装着される請求項1乃至請求項5のいずれか一に記載の発光素子ランプと;を具備することを特徴とする。
また、基板取付部は、熱伝導性のケースと一体に形成されているため、基板取付部からの熱は、拡開して形成された熱伝導性のケースに良好に伝導され、効果的に放熱される。
しかも、基板取付部の裏面側が平坦面に形成され、前記ねじによって基板取付部がカバーの環状の接続部側へ押圧固定されるので、簡単な構成によって効果的に放熱性を向上することができる。
請求項6に記載の発明によれば、前記発光素子ランプの奏する効果に加え、口金からの熱をソケットに伝導して効果的に放熱できる照明器具を提供できる。
さらに、基板取付部2cの外周面は、外方に露出するようになっている。つまり、ケース2の根元部2aの近傍における外周面は、外方に露出されて外気と接触するようになっている。
なお、基板取付部2cは、ケース2と別体に形成し、この別体に形成したものをケース2に熱的に結合するように取付けてもよい。また、ケース2の材料は、アルミニウムに限らず、熱伝導性の良好な金属材料又は樹脂材料等を用いることができる。さらに、ケース2の内周面は、アルマイト処理することが好ましい。アルマイト処理することにより、ケース2の放熱効果を高めることが可能となる。アルマイト処理すると、このケース2の内周面は、反射効果が低下するが、別途後述する反射体3aを設けているので、この反射効果の低下は、性能上支障がない。一方、ケース2の内周面を反射面として利用する場合には、鏡面加工等によって反射面を形成すればよい。
なお、本発明は、既存のビームランプの構成部材を用いることは必須ではない。
2b・・・照射開口部、2d・・・熱伝導性のケースの接続部、3・・・光源部、
3a・・・反射体、3b・・・入射開口、3c・・・反射面、
4・・・発光素子(LEDチップ)、5・・・熱伝導性のカバー、
5a・・・熱伝導性のカバーの接続部、6・・・絶縁性のカバー、
7・・・口金、9・・・基板、10・・・Oリング、12・・・点灯回路、
14・・・ねじ、20・・・照明器具、21・・・器具本体、23・・・ソケット
