LIGHTING DEVICE

PROBLEM TO BE SOLVED: To provide a lighting device which secures a wiring space on a rear surface side of a housing and enables improvement of workability.SOLUTION: A lighting device 10 includes a housing 15, a light source, and a control unit 18. The light source is provided at a front surface side of the housing 15. The control unit 18 collectively houses a sensor 57, a sensor substrate 58, and a power supply substrate 59 in a case 56 and is arranged at a rear surface side of the housing 15. The sensor substrate 58 has a sensor circuit 71 for acquiring a signal detected by the sensor 57. The power supply substrate 59 has a power supply circuit 72 for providing power supply to the light source according to the signal acquired by the sensor circuit 71.SELECTED DRAWING: Figure 1 【課題】筐体の裏面側の配線スペースを確保し、施工性を向上できる照明装置を提供する。【解決手段】照明装置10は、筐体15、光源および制御ユニット18を備える。光源は、筐体15の表面側に設けられる。制御ユニット18は、ケース56にセンサ57、センサ基板58および電源基板59を一括に収め、筐体15の裏面側に配設される。センサ基板58は、センサ57が検出する信号を取得するセンサ回路71を有する。電源基板59は、センサ回路71が取得する信号に応じて光源へ電源を供給する電源回路72を有する。【選択図】図１
