PROBLEM TO BE SOLVED: To reduce output to a light source depending on the priority according to the usage of the light source at the time of high temperature.SOLUTION: Multiple converter circuits 111, 112 are connected, respectively, with multiple types of light sources 21, 22. A temperature detector 12 detects internal temperature of a case 15 housing the multiple converter circuits 111, 112 and a control circuit 13. Priorities of lowering the output when the internal temperature goes above a threshold are set according to the usage of the light sources 21, 22, respectively, in the control circuit 13. The control circuit 13 is configured to control the outputs from the multiple converter circuits 111, 112, so as to reduce the output to a light source of high priority preferentially, when the internal temperature goes above a threshold.SELECTED DRAWING: Figure 1

    【課題】高温時に光源の用途に応じた優先度にしたがって光源への出力を低減する。【解決手段】複数のコンバータ回路111,112にはそれぞれ複数種類の光源21,22が接続されている。温度検出部12は、複数のコンバータ回路111,112及び制御回路13が収納されたケース15の内部温度を検出する。制御回路13には、複数種類の光源21,22のそれぞれについて、内部温度が閾値以上になったときに出力を低下させる優先度が、光源21,22の用途に応じて設定されている。制御回路13は、内部温度が閾値以上になったときに、優先度が高い光源への出力を優先的に低減させるように、複数のコンバータ回路111,112の出力を制御するように構成されている。【選択図】図1
