Abstract
A lighting system and a multi-mode lighting device thereof are provided. The multi-mode lighting device includes a wireless communication unit, a lighting unit, a projection unit, and a processing unit. The processing unit is coupled to the wireless communication unit, the lighting unit, and the projection unit. The processing unit is configured to selectively operate in one of multiple modes, wherein the multiple modes include a lighting mode and a projection mode. The processing unit is adapted to control the lighting unit to provide illumination light when the processing unit operates in the lighting mode. The processing unit is adapted to receive a video signal provided by an electronic device via the wireless communication unit and control the projection unit to project an image based on the video signal when the processing unit operates in the projection mode.
