Abstract

The invention relates to the field of illumination adjustment, in particular to an illumination system adjustment method and device and a computer storage medium, and the illumination system adjustment method comprises the steps: obtaining an illumination adjustment instruction; determining a target voltage characteristic parameter corresponding to at least one illumination adjustment parameter based on a preset relationship between the illumination adjustment parameters and the voltage characteristic parameters; generating a target voltage control signal corresponding to the illumination adjustment instruction according to the target voltage characteristic parameter; adjusting the output voltage of the voltage source based on the target voltage control signal to obtain a target voltage carrying a target voltage characteristic parameter, the target voltage being a continuous function of time and being a periodic function of time; by obtaining the target voltage carrying the target voltage characteristic parameter, the control of the post-stage circuit is realized, and the target voltage is a continuous function of time, so that the voltage value can be prevented from being in a chopping state, the sudden change of the voltage value is avoided, and the influence of the voltage change on the load device is reduced.

Description

technical field [0001] The present application is in the field of lighting adjustment, and in particular, relates to a lighting system adjustment method, device, and computer storage medium. Background technique [0002] see figure 1 , In the existing light adjustment and color matching system, the front-stage constant voltage circuit provides DC voltage to the latter-stage constant current circuit through the bus, and the latter-stage constant current circuit supplies power to the LED light source; after the switch tubes are connected in series on the bus, the PWM chopper The dimming control module controls the on-off of the switch tube, so that the bus voltage received by the rear-stage load is the PWM chopping voltage, such as a square wave voltage; by changing the duty cycle of the PWM chopping voltage, the rear-stage LED light source receives The power is changed so that the adjustment of the light source of the lighting system is realized. [0003] However, when the ...
