including COB downlight, the CPS and PMF. Three pantents completely solve the LED use in the field of technical problems, "Optical efficiency of 30-50%, zero attenuation, highlights and color to good effect. Solid crystal, wire, can be assembled to complete lamps, simplifying the production process, shortening the production cycle, making large-scale production of LED lamps is more simple. The technique has been applied for international and domestic patents, domestic patent number: 200,810,067,358.0; 200820094165.X; PCT: PCT/CN2008/071409.
