Wireless butt joint bathtub lamp system

The utility model discloses a wireless butt joint bathtub lamp system comprising an emitter including a switch controller, a power supply device, a first controller, a power supply modulation device, an interference isolation device, a signal-electric isolation device, a power amplification circuit, a signal generator, a modulator, a transmitting coil and a first energy storage device. The system uses near field induction technology in the wireless electric power conveying technology, and the emitter can convert DC electric energy into near field induction needed electromagnetic waves, and intermittence power supply can generate different control signals so as to modulate the electromagnetic waves, thus realizing one-way control signal transmission in wireless power transmission, and controlling colors and brightness work modes of the bathtub lamp.
