ABSTRACT:
An LED lamp includes an optical part, a heat dissipation part and an electric part. The optical part includes main and auxiliary LED light sources thermally attached to the heat dissipation part. The electric part includes a rechargeable battery and a circuitry for converting an external AC power source into first and second DC power sources. The auxiliary LED light source is connected to the first DC power source for providing an auxiliary illumination when the external AC power source is normally supplied or to the rechargeable battery for providing an emergency illumination when the external AC power source is interrupted. The main LED light source is connected to the second DC power source for providing normal illumination when the external AC power source is supplied normally. Photoelectric switches are also provided for controlling the action of the auxiliary LED light source.
