Title: LIGHT FIXTURE
Abstract:
A light fixture comprises a box-like housing (12), and multiple LED light-emitting elements (20) are provided at the light-emitting surface (19) of the box-like housing (12). A wire (13) and an electrical plug (14) for connecting to a power supply are provided on a non-light-emitting surface of the box-like housing (12). A transparent or semitransparent outer shield (16) is provided outside the light-emitting surface (19) of the box-like housing (12). A control device (17) comprising multiple control units is provided inside the box-like housing (12). The multiple control units comprise: a control unit which detects a moving object by means of microwave transmission and control on/off of lighting; a control unit which turns off the lighting after a set delay time after no moving object is detected; a control unit which measures illumination intensity of an ambient environment and controls on/off of the lighting; and a control unit which controls an illumination intensity percentage. A microwave transmitting device of the control unit which detects a moving object by means of microwave transmission and control on/off of the lighting is provided at the light-emitting surface (19) of the box-like housing (12).
