Abstract

The invention relates to a method for improving the lightening efficiency of an LED light and a light fitting thereof. The method is characterized in that CdSe/ZnS quantum dot material is added to LEDphosphor powder, and the mixture is packaged after being evenly mixed; the addition is (1-10)/10000, or a layer of CdS/ZnS quantum dot material with the width being 100 nanometers to 100 micrometersis coated on the inner surface of an LED light cover, thereby obtaining the light fitting. The light fitting comprises LED granules (1), a light cover (2), quantum dots (3), a packaging adhesive (4) and a transparent cover (5), wherein the quantum dots (3) are dispersed in the packaging adhesive (4) or coated on the inner surface of the transparent cover (5), the packaging adhesive (4) is filled in the light cover (2), the transparent cover (5) is arranged on the light cover (2), the LED granule (1) is positioned in the light cover (2) by the packaging adhesive (4), and the quantum dots (3) are the CdS/ZnS quantum dot material. The invention can reduce the LED granules, thereby obtaining the color with a full spectrum.

Description

technical field [0001] The invention relates to an LED lamp and a method for improving its luminous efficiency, in particular to a method for improving the luminous efficiency by adding a quantum dot material into an LED packaging fluorescent material and a method for improving the luminous efficiency thereof. Method for luminous efficiency of lamps and lamps thereof. Background technique [0002] Lighting products that directly use blue chips to excite YAG phosphors to emit white light are called semiconductor lighting products. Compared with traditional incandescent lamps, white LED lighting products can save 80%-90% of electricity; and the life span can reach 80,000-100,000 hours, which is more than 10 times that of incandescent lamps. With such remarkable advantages as long life, it is the most competitive green light source product in the 21st century. With the rapid development of semiconductor technology, the current high-power LED lighting technology has a tendency...
