Problems solved by technology

Although this method can realize the continuous adjustment of the color temperature of the lighting light, it requires the combination of LEDs with high color temperature and LEDs with low color temperature, which wastes the LEDs with intermediate color temperature. Therefore, it is of great significance to further simplify the way of adjusting the color temperature of the light source

Abstract

The invention discloses an adjustment method of color temperature of LED (Light Emitting Diode) light and a color temperature adjustable LED lamp. The adjustment method of the color temperature of the LED light comprises the following steps of (S1) selecting a blue LED light source and a fluorescent screen; (S2) controlling a part of blue light emitted by the blue LED light source to make contact with the fluorescent screen so as to generate white light; and (S3) mixing the white light and the other part of blue light emitted by the blue LED light source so as to generate LED light, wherein the color temperature of the LED light is adjusted by adjusting the energy ratio of the white light to the other part of blue light. According to the adjustment method of the color temperature of the LED light, an implementation mode is simple and is easy to realize.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a method for adjusting the color temperature of LED lighting light and an LED lighting lamp with adjustable color temperature. Background technique [0002] As a light source, LED has been widely used in lighting equipment. It has the advantages of energy saving, low price, long life, and LED light source can be controlled by a single string. People's requirements for lighting sources are getting higher and higher, and the adjustable color temperature can meet people's different requirements for color attributes. For example, Europeans prefer light sources with cool color temperatures, while Asians prefer light sources with warm color temperatures. Cool-toned light sources usually give people a profound, calm, and elegant feeling; warm-toned light sources give people a warm, festive, and gentle feeling. Therefore, lighting equipment with adjustable color temperature can meet people's...
