PWM SIGNAL AND POWER TRANSMISSION METHOD FOR WIRELESS BATHTUB LAMP

Provided is a PWM signal and power transmission method for a wireless bathtub lamp. Valid level signals of PWM signals generated by a signal source to control an R-LED module/G-LED module/B-LED module and a corresponding high-frequency signal generated by a fixed-frequency generation device are modulated respectively by means of the modulating amplifiers to generate wireless power transmission signals, and the wireless power transmission signals are amplified and output, corresponding transmitting resonators and receiving resonators can work together to realize wireless transmission of wireless power transmission signals and power; moreover, corresponding PWM signals in the wireless power transmission signals are extracted by means of wireless power transmission signal extraction modules and output to drive the R-LED module/G-LED module/B-LED module to change light, the transmission speed of the PWM signals is effectively increased, the maximum wireless transmission power is realized, the power utilization rate and reliability of the wireless lamp are improved.
