Abstract

The invention discloses an LED light and color regulation method and system. The system comprises an upper computer, a main communication module, a main controller, a light control system module and an LED lamp array module. The upper computer generates PWM regulation data and transmits the PWM regulation data to the light control module, the light control module generates the PWM wave to controlan LED lamp array for light and color regulation, wherein the PWM regulation data is calculated and obtained through adoption of the genetic simulated annealing algorithm. The genetic simulated annealing algorithm is applied to the optimization solution for the luminous flux of the four-color LED hybrid light source under the multi-constraint constraint with fast convergence speed and high efficiency, the global optimal solution can be obtained with a large probability, and the high luminous flux hybrid light source with the optimal light source performance can be obtained. The method is employed to optimize the hybrid light source to achieve the accurate control of the color temperature of the hybrid light and obtain the optimal 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...
