<p>PROBLEM TO BE SOLVED: To prevent a lamp from being suddenly extinguished even when a human body is stationary within a detection range, by providing a detection sensor, timer lighting-actuating a preset time lamp in response to detection action of the detection sensor and an extinguishing notice means. SOLUTION: In a detection sensor 1, movement of a human body is detected, an electric signal is output. An equipment main unit 2 has a timer lighting- actuating a peset time lamp in response to detection action of the sensor 1, the lamp is covered with a permeable cover 4, also an extinguishing notice means 3 is provided in the inside. In this means 3, when the human body is stationary within a detection range of the sensor 1, when the timer is made adjacent to its preset time, brightness of the lamp is changed. In this way, a user can be informed of extinguishing maring, when the human body moves before the elapse of present time, this movement is detected by the sensor 1, preset time lighting of the timer is restarted. Accordingly, even when he is stationary within a detection range of the sensor 1, rapid extinguishing can be prevented, so that the lamp can be used without anxiety in a stationary space such as a toilet or the like.</p> |
