  • Patent number: 8648538
    Abstract: A biolux lighting apparatus comprising a timer for counting a dark adaptation time, a sensor for sensing the motion of an object, a lamp having an adjustable brightness, and a control unit in which a dark adaptation threshold value is set and which controls each unit. The control unit controls the lamp to emit light at a set maximum brightness level when an object sensed signal is transmitted by the sensor, controls the timer to start counting when the light from the lamp has reached the maximum brightness level such that the brightness level of the lamp is lowered by the intensity of illumination within the set dark adaptation threshold value whenever a counting signal is generated by the timer. The control unit controls the timer to stop counting to maintain a set standard brightness level when the light from the lamp has reached the set standard brightness level.
