Abstract

The invention relates to a high-power LED (light-emitting diode) lamp, which mainly solves the technical problems that the LED lamp of the prior art is made of plastic material and is easily affected with damp and aged, has poor heat resistance and is easily allochromatic under high temperature and short-wave illumination. The LED lamp comprises a ceramic bracket, a round groove is arranged in the middle of the bracket, the bottom of the round groove is provided with four high-power lighting chips which are respectively white, red, green and blue, and the round groove is provided with a lampshade. The LED lamp disclosed by the invention has the advantages that the bracket is made of ceramics, has good heat conduction and insulation properties, does not absorb moisture, and resists aging and high temperature. The LED lamp is formed by integrating lighting chips with different colors, and has good color regulating and light regulating effects.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a ceramic packaged high-power LED lamp with good thermal conductivity and insulation performance, high temperature resistance and corrosion resistance, and low cost. Background technique [0002] At present, the domestically produced LED lamp bases are generally made of plastic materials. Plastic materials have the advantages of excellent adhesion, electrical insulation, sealing and low cost. However, with the continuous improvement of LED brightness and power, the LED lamp manufacturing The material puts forward higher requirements, and the plastic material itself has the defects of hygroscopicity, easy aging, poor heat resistance, high temperature and easy discoloration under short-wave light exposure, which greatly affects and shortens the performance and service life of LED devices. In addition, traditional LED lamps use blue light chips to excite phosphors to produce yellow light or yellow-gre...
