An intelligent lighting device comprises at least one lamp housing (1) that can be mounted on an object, wherein at least one light-emitting unit (2) and at least one light gathering unit (3) are provided in the lamp housing (1). The light-emitting unit (2) is disposed in the lamp housing (1), and can be powered to emit light to the outside of the lamp housing (1). The light gathering unit (3) is also disposed in the lamp housing (1), and faces an area (4) to be detected outside the lamp housing. The light gathering unit (3) can sense the brightness of ambient light of the area (4) to be detected, compare the brightness of the ambient light with a preset ambient brightness value to obtain through calculation a difference of the ambient brightness, and control the light-emitting unit to emit light of the brightness corresponding to the difference. The intelligent lighting device can adjust illumination according to the ambient brightness, and can save electric power. |
