PROBLEM TO BE SOLVED: To provide a projector capable of performing desired lighting control, even when the maximum rating on output is changed by a use environment.SOLUTION: The projector includes laser light sources 103 to 105 which output a laser beam, sensors 119 to 121 which detect the temperatures of the laser light sources 103 to 105, a light reduction part 112 which reduces and transmits the laser beam outputted by the laser light sources 103 to 105, and a control part 101 which controls the output of the laser light sources 103 to 105 and the transmittance of the light reduction part 112. The control part 101 performs dimming control for changing the output of the laser light sources 103 to 105 when a predetermined light quantity is outputted and the transmittance of the light reduction part 112, according to the temperatures of the laser light sources 103 to 105 detected by the sensors 119 to 121.SELECTED DRAWING: Figure 3

    【課題】使用環境により出力に関する最大定格が変化した場合でも、所望の調光を行うことができるプロジェクタを提供する。【解決手段】レーザ光を出力するレーザ光源103〜105と、レーザ光源103〜105の温度を検出するセンサ119〜121と、レーザ光源103〜105により出力されたレーザ光を減光させて透過させる減光部112と、レーザ光源103〜105の出力、および、減光部112の透過率を制御する制御部101と、を備え、制御部101は、センサ119〜121により検出されたレーザ光源103〜105の温度に応じて、所定の光量を出力するときのレーザ光源103〜105の出力と減光部112の透過率とを変化させる調光制御を行う。【選択図】図3
