<p>PROBLEM TO BE SOLVED: To facilitate time setting in a lighting control device for time-zone which controls the state of lighting. SOLUTION: A sensor remote control device 8 having a human-body sensor 4 sensing the approach of persons and transmitting an infrared remote-control signal of lighting command toward a luminaire mounted on a ceiling is installed on a wall surface of a passage, etc., in a house. For example, this device is set up so that the luminaire is turned off regardless of whether or not persons are present during the daytime, set up so that the luminaire is lighted in a modulated manner during night time and that the luminaire is fully lighted, when the sensor remote control device senses that persons come home or approach, and set up so that the luminaire is turned off during the nighttime and that, when persons approach, the luminaire is lighted at a low level of modulated light (lower brightness) not causing them to feel the glare of the light, thus the state of lighting of the luminaire is time-zone controlled. To time-zone control the state of lighting, this device is provided with a time-setting means comprising a slidingly operated time-selecting part 9, such as a variable resistor and time-setting parts 10, 11, 12 using set-up buttons.</p> |
