Title:
RED LIGHT COMPENSATION METHOD AND DEVICE FOR RGB LAMP AND RGB LAMP
Document Type and Number:
WIPO Patent Application WO/2019/120230
Kind Code:
A1
Abstract:
A red light compensation method and device for an RGB lamps and an RGB lamp are provided. The method includes acquiring an RGB lamp temperature information detected by a thermistor, determining a red light PWM duty cycle compensation factor corresponding to the RGB lamp temperature information according to a preset linear relationship between RGB lamp temperatures and red PWM (pulse width modulation) duty cycle compensation factors, determining a PWM count value according to the red light PWM duty cycle compensation factor corresponding to the RGB lamp temperature information, and outputting the control current to red light in the RGB lamp according to the PWM count value.
