用途に用いられ、歯科用途における光硬化性化合物を照らして硬化させる光を提供する照
明デバイスシステムに関する。
Tdischarge=C(V1-V2)/I
となり、ここでV1はフル充電電圧であり、V2は最低動作電圧である。本発明の一実施形態では、1つもしくは複数のLED素子、または光源40を構成するアレイをドライブする電源は、ブーストパルス幅変調(PWM)電流源、またはバックPWM電流源でもよい。あるいは、バックブーストPWM電流源を利用することもできる。また、以下で説明するように、フライバック電流源またはSEPIC電流源を用いることもできる。バックブースト接続形態は、ウルトラキャパシタが十分に充電されており、その電圧がLEDに必要な順方向電圧より高くなり得る場合に、1つまたは複数のLED素子に電力を供給することによって、デバイス10のための所望の長い実行時間(放電時間)を提供する。さらに、このような接続形態は、放電によってウルトラキャパシタの充電がLEDの順方向電圧より低くなる場合に、LEDに電力を同様に供給する。一実施形態では、例えば、2つの100ファラッドのウルトラキャパシタを用いて、1回の充電に対して30〜40回の、それぞれ10秒の放電硬化サイクルを達成することができる。
