Description
まず、図1を用いて、本発明が適用される場面の一例について説明する。図1は、本実施の形態に係る電源装置100の一構成例を示したブロック図である。図1に示すように、電源装置100は、たとえばスイッチング電源装置である。電源装置100は、外部からの入力電圧を受ける入力部10と、電源部20と、出力部30とを含む。
図3は、図1に示したLED回路12(点灯回路)の構成例を示した回路図である。図3を参照して、LED回路12は、ダイオード50と、ツェナーダイオード51,52,53,54と、抵抗61,62,63,64と、LED71,72,73,74とを含む。
表示回路81b,81c,81dの各々は、LEDを有する。たとえば電源装置100の電源部20に入力電圧が正常に入力される場合に、表示回路81dのLEDが点灯する。電源装置100から直流電圧が出力されている場合、表示回路81bのLEDが点灯する。一方、電源装置100の内部に異常が発生した場合には、表示回路81cのLEDが点灯する。たとえば、表示回路81dおよび表示回路81bは、図1に示したLED回路12およびLED回路31のそれぞれの実現例である。
以上のように、本実施形態は以下のような開示を含む。
外部からの入力電圧を受ける入力部(10)と、
前記入力部(10)を通して入力された前記入力電圧から電源電圧を発生させる電源部(20)と、
前記電源電圧を出力する出力端子(32,33)を含む出力部(30)と、
前記入力部(10)に接続されて、前記入力電圧が印加されることにより点灯する点灯回路(12)とを備え、
前記点灯回路(12)は、前記入力電圧に応じて、点灯の態様を異ならせる、電源装置(100)。
前記点灯回路(12)は、複数の発光素子(71~74)を含み、前記複数の発光素子(71~74)のうちの点灯する発光素子の数を前記入力電圧の大きさに応じて変化させる、構成1に記載の電源装置(100)。
前記点灯回路(12)は、
前記複数の発光素子(71~74)のそれぞれの高電圧側に接続された複数のツェナーダイオード(51~54)をさらに含み、
前記複数のツェナーダイオード(51~54)は直列に接続されている、構成2に記載の電源装置(100)。
