Abstract:
1. A method of disinfection and lighting by using LEDs, comprising: fixing two kinds of LEDs, i.e., lighting LEDs, and UV-LEDs, on a circuit board evenly and mixedly, wherein a separator is also provided on the circuit board to separate UV light emitted by said UV-LEDs and illumination light emitted by said lighting LEDs, meanwhile, a controlling circuit module having a function of mode switching controls the UV-LEDs and the lighting LEDs, in such a manner that the functions of UV-LED disinfection and LED lighting are combined well in a same device, wherein the separator is a reflecting cup, in such a manner that the light emitted by the device combined by the lighting LEDs and the UV-LEDs is homogeneous and has a strong directionality, so the strong UV light does not hurt people in some situations, and the lighting LEDs in the same LED device is not hurt by the strong UV light.
