Latest Patents

Wenkai Zhao holds a patent for an "LED dimming method, dimming controller and system." This invention discloses a method where, in a phase where the duty cycle of a PWM signal does not exceed a first threshold, every n periods of the PWM signal is treated as one set. Each set serves as an output unit, allowing the duty cycle of the PWM signal to be adjusted by incrementing or decrementing an average duty cycle by a first predetermined amount ΔP1, which is less than 0.2%. This method ensures that the output current of an LED can be finely tuned, particularly when the first threshold is set at 10%, allowing for precise identification of duty cycle values within the range of 0-10%.
