Abstract: A high efficiency radiator and a manufacturing method thereof are disclosed. The high efficiency radiator includes: a radiating set, a closed ring and a basement membrane. The basement membrane has a chamber, the radiating set is provided in the chamber of the basement. The closed ring is provided on a connecting gap between the radiating set and the basement membrane. The radiating set comprises a cover plate and a plurality of radiating fins. The radiating fins are provided on a surface of the cover plate at an equal interval. The radiating fins are provided in the chamber of the basement membrane, and the cover plate is provided on an opening of the basement membrane and connected with the closed ring. The present invention has advantages of high radiation efficiency, light weight, low cost and wide application.

Abstract: A method of disinfection and lighting by using LEDs and an LED device thereof are provided. Two kinds of LEDs, i.e., the lighting LEDs, and the UV-LEDs, are fixed on a circuit board evenly and mixedly in a certain way, and a separator is also provided on the circuit board. 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. The method replaces a conventional method of sterilization and disinfection using ultraviolet (UV) rays emitted by a low pressure mercury vapor lamp. After being treated with light distribution by the separator, directionality of light emitted by the LED is stronger, and the LED is easier to operate.
