Problems solved by technology

However, with the increase in the number of channels, higher requirements are put forward for the control of LED lighting systems, which has also become an important technical obstacle that has caused the market to delay the launch of multi-channel LED lighting systems.
At this stage, it is still impossible to effectively solve the adjustment of any target spectrum by using a multi-channel LED lighting system

Abstract

The invention provides a spectrum adjustment method for a multi-channel LED (Light-Emitting Diode) illumination system. The method comprises the following steps of presetting a spectrum adjustment target variable and a requirement thereof according to an illumination application demand; generating a synthetic spectrum of the multi-channel LED illumination system; calculating a target variable value of the synthetic spectrum; judging whether the target variable value of the synthetic spectrum satisfies the requirement of the preset spectrum adjustment target variable or not, and if not, regenerating the synthetic spectrum of the multi-channel LED illumination system until the target variable value of the obtained synthetic spectrum satisfies the requirement of the preset spectrum adjustmenttarget variable to obtain the synthetic spectrum which meets the illumination application demand. According to the spectrum adjustment method for the multi-channel LED illumination system, the adjustment for any target spectrum can be implemented, and the illumination control for the multi-channel LED illumination system can be effectively implemented, thereby providing important technical support for the research and development of related products.

Description

technical field [0001] The application belongs to the technical field of lighting, and in particular relates to a method for adjusting the spectrum of a multi-channel LED lighting system. Background technique [0002] With the rapid development of LED and intelligent control technology, and the continuous deepening of human research on the impact of light on people's body and mind, the research and application of light environment has developed from the original visual effect to emotions, sleep, cognition, rhythm, etc. With regard to various aspects of light and health issues, lighting has gradually moved from static lighting to dynamic lighting. The so-called dynamic lighting is to adjust the lighting spectrum and intensity according to the brightness of the surrounding environment, so as to create a healthy, comfortable and efficient light environment for people. [0003] Since LED technology has good control characteristics, narrow spectral band and rich spectral selecti...
