Description
第1の実施形態は、照明装置1として、図6に示す電球型LEDランプを用いる。
第1の実施形態では、各LED直列回路7が有するLED素子Tの数を、この直列回路7に整流装置5を経て印加される電圧が商用電源2の出力電圧の70%〜90%となるように設定した。これは、電源電圧が変動することに起因した結果である。すなわち、商用電源2の電圧は、一般に、10%の範囲内で変動する。例えば定格入力電圧が100Vの交流電源の場合、一般的に、電圧変動を考慮すると、その実効値は(100±10)Vとなる。つまり、90Vから110Vの間で変化する。
例えば、前記実施の形態では、商用電源の定格入力電圧を100Vとしたが、電圧値はこれに限定されるものではない。例えば120V、200V、220V、230V等の種々の定格入力電圧を有する商用電源を用いても、本発明を適用することができる。
