Abstract

The invention discloses a brightness and color temperature controlling system for an LED (light-emitting diode) lamp. The brightness and color temperature controlling system comprises an LED module, a control chip and at least one driving module, wherein the LED module includes a plurality of LED illuminating units, the output end of the control chip is connected with the input end of the driving module, and the output end of the driving module is connected with the plurality of LED illuminating units. According to the brightness and color temperature controlling system for the LED lamp, brightness and color temperature of the LED lamp can be controlled individually, and brightness of the LED lamp can be freely adjusted when a color temperature parameter is fixed, so that brightness of the LED lamp does not change when color temperature of the LED lamp is adjusted.

Description

technical field [0001] The invention belongs to the field of LED lamp lighting, and in particular relates to a control system for brightness and color temperature of an LED lamp. Background technique [0002] Due to the disadvantages of incandescent lamps such as high energy consumption and short life, all countries in the world have relevant policies to eliminate incandescent lamps, while LED lamps have the characteristics of high brightness, safety, and low calorific value. Therefore, LED lamps are widely used in conventional lighting in the light fixture. The luminous color of daily LED lights is mainly white, because white light is closest to sunlight, but the LED lights that emit white light are emitted by the blue light emitted by the blue light-emitting chip to excite the phosphor and then emit white light. The characteristics of white LED lights determine their luminescence The brightness value and color temperature value of the color, so the white light emi...
