White-light LED moving head lamp based on glass conversion

Abstract

The invention relates to a white-light LED moving head lamp based on glass conversion. The white-light LED moving head lamp comprises a lamp cap and a lamp holder for mounting the lamp cap, the lamp cap comprises a light source and a lamp board for mounting the light source, and the lamp holder comprises an upper shell and a bottom cover. The upper shell is composed of a lamp tube, a U-shaped armassembly located below the lamp tube and a fixing board A fixedly connecting the lamp tube with the U-shaped arm assembly, and the U-shaped arm assembly is rotatably connected with the bottom cover. The light source is composed of an LED chip fixed to the lamp board and a light converting medium covering the light emitting face of the LED chip, the light converting medium is glass with a yellow oryellow green body, and light emitted by the LED chip is converted through the light converting medium, so that high-stability white light is obtained. According to the white-light LED moving head lamp based on glass conversion, the glass with the yellow or yellow green body is adopted as the light source so as to obtain the high-stability white light, and rotation of the lamp cap can be controlled in a positioned mode.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a glass-converted white LED moving head light. Background technique [0002] At present, the light sources used in traditional moving head lights are all white LED packages, which are packaged with glue and phosphor powder. The disadvantage is that attenuation and color drift will occur when the chip generates high heat, especially for continuous long With the use of time, the heat generated by the LED chip is extremely high, which will cause the glue and phosphor to age rapidly, seriously affecting the life and light efficiency of the product. Moreover, the existing moving head lights have a single moving function and low control precision. Contents of the invention [0003] The object of the present invention is to address the above deficiencies and provide a glass-converted white LED moving head that uses yellow or yellow-green glass as the light source to obtain highly s...
