Problems solved by technology

At present, the control of full-color LED lights can achieve soft dimming and smooth transition dynamic change effects. Usually, full-color RGB lamps have rich color change effects. Channel gray level adjustment, the previous control technology used to regularly increase or decrease the channel value to implement the control process, but because the initial value of each channel is inconsistent, there is an error in the control target value of each channel, this control method It will make the adjustment ratio of each channel uncoordinated, resulting in the imbalance of color changes in the adjustment process, resulting in uncontrollable lighting color consequences.

Abstract

The invention discloses a control system with high stability of LED color, which includes a system for providing new value input, current target control value, control target value, control current value, fixed duration resolution, system control timing cumulative value, and control interval length The database; the database is respectively connected with the control trigger module, the parameter operation module, and the control execution module, and the control trigger module, the parameter operation module, and the control execution module are connected in sequence. The invention also discloses a method for realizing a control system with high LED color stability. The invention has the characteristics of being able to keep the color highly stable without shifting during the process of color adjustment and grayscale adjustment of the full-color LED lamp, and having better color stability and the like.

Description

technical field [0001] The invention relates to an LED color control technology, in particular to a high-stability LED color control system and a realization method thereof. Background technique [0002] With the wide application of landscape lighting and stage lighting, digital dimming technology has become an indispensable part of it. At present, the control of full-color LED lights can achieve soft dimming and smooth transition dynamic change effects. Usually, full-color RGB lamps have rich color change effects. Channel gray level adjustment, the previous control technology used to regularly increase or decrease the channel value to implement the control process, but because the initial value of each channel is inconsistent, there is an error in the control target value of each channel, this control method It will make the adjustment ratio of each channel uncoordinated, resulting in the imbalance of color changes during the adjustment process, resulting in uncontrollable...
