Abstract:
A lifestyle LED security light including a light-emitting unit configured with two sets of LED loads respectively emitting different color temperature lights is disclosed. At dusk the light-emitting unit is automatically turned on for a first level illumination with a low color temperature light featuring an aesthetic night view with the motion sensor being deactivated for a time duration, and then the light emitting unit is changed to a second level illumination and at the same time the motion sensor is activated, wherein when the motion sensor detects a motion intrusion, the light-emitting unit is instantly switched to perform a third level illumination with a a high light intensity and a high color temperature light. The color temperatures of the first level illumination and the third level illumination are respectively adjustable by simultaneously and reversely adjusting the electric powers respectively allocated to the two sets of LED loads.
