Description
LEDランプ106への通電電流は、定電流素子105により定電流化が図られている。
AC入力の正側においては、直列接続されたキャパシタCPT1〜CPTnがACH入力端子1301aを介してAC入力端子H108に接続され、ACL入力端子1301bに向けて通電されて各々充電される。
Claims (1)
- 入力端から交流または直流電源が入力される電源装置部と、この電源装置部に接続される1個または直列接続された複数個のLEDを備え、前記電源装置部は、入力端後に設けた整流用ダイオードブリッジと、前記LEDに流れる電流を検知する電流検出回路部と、所定周波数のパルス信号を発振する発振回路部と、発振回路部に接続されたスイッチング制御回路部と、スイッチング制御回路部に接続されたスイッチング素子とを備え、
スイッチング制御回路部は前記発振回路部が発振の繰り返し信号を出力してスイッチング素子を100Hz以上の周波数でON、OFF制御するものであって、
且つ電流検出回路部からの検知信号に基づいて平均で所定の電流になるようにパルスあたりのON・OFF時間比率変調であるPWM制御したパルス信号を前記スイッチング素子に供給して前記LEDを点灯することを特徴とするLEDランプ装置。
