<p>A light device (2,2') includes one or more light members (32) mounted behind a hood (21) to emit lights. A remote detecting device (40) is used to detect whether one or more users go toward or go close to the light device (2,2') or not, and to actuate the light member (32) to brighten when the users are detected to go toward the light device (2,2'). The light device (2,2') may thus be actuated to brighten without being actuated or contacted by the users or without being operated or contacted by the users manually. A control device (43) is used to actuate the light member (32) to brighten. The remote detecting device (40) includes a ray emitting device (43) to emit a ray to detect whether the user goes toward the light device (2,2') or not.</p> |
