Patent ID: 8643287

Claim:
A lighting device with switchable day/night illumination mode comprising: a main controlling unit; a driving unit, being coupled to the main controlling unit; a lighting unit, being coupled to the driving unit and having a plurality of light-emitting devices, wherein the main controlling unit controls the driving unit to drive the lighting unit, so as to output a visible light; a light filtering unit, being disposed over a light-emitting surface of the lighting unit, used for filtering the visible light and making the visible light become a visible light with a specific wavelength; an illumination mode switching unit, being coupled to the main controlling unit, wherein the illumination mode switching unit is used for controlling and switching the light filtering unit, so that the light filtering unit shows and covers the light-emitting surface of the lighting unit, and then the visible light outputted from the lighting unit is filtered by the light filtering unit and becomes the visible light with the specific wavelength; moreover, the illumination mode switching unit is able to control and switch the light filtering unit, such that the light filtering unit is withdrawn and stops covering the light-emitting surface of the lighting unit, and then the lighting unit outputs the visible light; and a power management unit, being coupled to the main controlling unit for providing the power to the main controlling unit.
