Patent ID: 8648538

Claim:
A biolux lighting apparatus comprising: a timer counting a preset time and outputting a counting signal when the timer counts the preset time; a motion sensor sensing a motion of an object; a lamp with an adjustable brightness level; and a control unit controlling the timer, the motion sensor, and the lamp, the control unit controlling the lamp to emit light at a set maximum brightness level when the control unit receives an object sensed signal from the motion sensor that an object moves into a predetermined range, controlling the timer to repeatedly count a first dark adaption time when the brightness level of the lamp reaches the set maximum brightness level, controlling the brightness level of the lamp to be lowered by an intensity of illumination within a first dark adaptation threshold value at each time the control unit receives a first counting signal generated by the timer after counting the first dark adaption time, controlling the timer to stop counting when the brightness level of the lamp reaches a set standard brightness level, and controlling the lamp to maintain the set standard brightness level.
