Abstract

The invention discloses an LED dimming and color adjustment method and system, comprising a host computer, a master communication module, a slave communication module, a master controller, a light control system control module and an LED lamp array module, and the host computer generates PWM adjustment data It is transmitted to the lamp control module, and the lamp control module generates PWM waves to control the LED lamp array to perform dimming and color adjustment, wherein the PWM adjustment data is calculated according to the genetic simulated annealing algorithm. The invention applies the genetic simulated annealing algorithm to the optimization solution of the luminous flux of the four-color LED mixed light source under multivariate constraints, has fast convergence speed and high efficiency, can obtain the global optimal solution with a relatively high probability, and can obtain the light and color performance Optimal high luminous flux mixed light source. Using the above method to optimize the mixed light source can not only achieve precise control of the color temperature of the mixed light, but also obtain the best display effect at the target color temperature.

Description

technical field [0001] The invention relates to the technical field of LED dimming and color adjustment, in particular to an intelligent LED dimming and color adjustment lighting method and system. Background technique [0002] Light-emitting diode (LED) light source has many advantages such as small size, low energy consumption, low voltage and good controllability, and has gradually replaced incandescent lamps and fluorescent lamps that were widely used in the past. The trend of future development. At present, most of the LED lighting products on the market are fixed colors and cannot be adjusted. Most of the lighting products use various ordinary switches to turn on and off the lamps. To achieve adjustable light intensity and color temperature to meet dynamic lighting under different conditions, it is necessary to regulate a variety of LED light sources. At present, red / green / blue (R / G / B) LEDs are widely used for light mixing, and the color temperature adjustment is rea...
