Description
また、開口部を通じて口金と電源部とを熱的に接続する、樹脂からなる熱伝導部材を備える。すなわち、口金と電源部とを熱的に接続する熱伝導部材は、開口部を通じて直接口金に密着するので、熱伝導部材を介して電源部で発生した熱を口金へ伝導することができる。
また、電源部は、口金側に配置される発熱部品を有する。これにより、発熱部品を口金に近接させることが可能となるので、発熱部品で発生した熱を効率的に口金に伝導し、口金から外部へ放熱することができる。
さらに、発熱部品は、交流を整流する整流素子又は整流素子で整流した直流をスイッチングするスイッチング素子の少なくとも一方を含む。これにより、発熱部品で発生した熱を口金から外部へ放熱することができる。
