<p>PROBLEM TO BE SOLVED: To provide an automatic lighting controller that prevents useless electricity consumption and prevents lights-out while a person is around within the sensing area after electricity sources are put on and that promptly moves into automatic lighting control by a human detection sensor. SOLUTION: A control system comprises a lamp 111, a lighting circuit part 112, a load output part 113, and a pyroelectric element human sensor 114. It also comprises a controller 115 whereby for a prescribed time T11 after lighting on the electric sources, a lamp 111 is lit, and for a prescribed time T12 after that, it monitors whether or not the human sensor detects the existence of a human being while the light is on and after the elapse of T12, the lamp 111 is kept on lighting whenever the sensor detects the existence of a human. When the human sensor does not detect the existence of a human, the lamp 111 is put out after an elapse of time T12, and when it detects the existence of a human, the controller 115 lights on the lamp 111 as the lighting time has started after an elapse of a time T12.</p> |
