1. A power and signal transmission method for a wireless lamp which comprises a lamp body and a lamp holder, wherein
the lamp body comprises an LED lamp, an LED drive module, a lamp body control module, a wireless carrier signal extraction module and a wireless power receiving module, the wireless power receiving module being electrically connected to the LED drive module, the lamp body control module and the wireless carrier signal extraction module, the LED drive module being electrically connected to the LED lamp for driving the LED lamp to change light emitted therefrom; and
the lamp holder comprises a power supply module, and a lamp holder control module and a wireless power transmission module which are electrically connected to the power supply module, the lamp holder control module being configured to receive a pulse control signal and send a carrier signal integrated with the pulse control signal to the wireless power transmission module;
the power and signal transmission method comprising:
S01: inputting an AC/DC to the power supply module of the lamp holder and inputting an irregular control signal to the lamp holder control module, and converting, by the lamp holder control module, the irregular control signal into a pulse control signal;
S02: integrating, by the lamp holder control module, each signal segment of the pulse control signal into a high-frequency signal with a preset frequency, wherein every time the lamp holder control module detects a signal segment, which turns into a high level from a low level, of the pulse control signal, a low level with a preset duration is correspondingly output from the high-frequency signal to form a carrier signal;
S03: outputting, by the lamp holder control module, the carrier signal to the wireless power supply transmission module;
S04: receiving the carrier signal, generating power and outputting the power to the LED drive module and the lamp body control module, by the wireless power receiving module;
S05: extracting, by the wireless carrier signal extraction module, the carrier signal received by the wireless power receiving module, and rectifying and shaping the carrier signal into a pulse control signal, which is then output to the lamp body control module;
S06: extracting, by the lamp body control module, the control signal from the pulse control signal, wherein the control signal is configured for changing light;
S07: correspondingly outputting, by the lamp body control module, a PWM signal to the LED drive module according to the extracted control signal; and
S08: driving, by the LED drive module, the LED lamp to change light emitted therefrom according to the PWM control signal.
