This effectively avoids the lamp body 2 shaking or shifting due to collisions or other reasons during use, which could cause misalignment between the transmitting resonant coil 3 and the corresponding receiving resonant coil 9, resulting in unstable power and signal transmission or interference. This ensures the stability of the wireless driving lamp board 203, improves power transmission efficiency, and enhances the user experience of the lamp. At the same time, the fixed connection between the lamp holder 1 and the lamp body 1 means that only a mounting hole for the lamp holder 1 needs to be made in the usage location such as a bathtub, without the need to drill a hole for the lamp body 1, thus reducing unnecessary drilling and simplifying disassembly and installation.
[0044] The base 201 is provided with at least one annular groove 2011, and the receiving resonant coil 9 is installed in the annular groove 2011. Each annular groove 2011 is provided with a second mounting plate 10 for closing the annular groove 2011.

[0047] First, the user connects the cable 103 inside the lamp holder 1 to the power supply and the LED controller respectively, and inputs signals to control the lighting effect of the lamp panel 202 through the LED controller. The signal processing module generates PWM signals to control the R-LED module and / or G-LED module and / or B-LED module based on the control signals input through the cable 103. By adjusting the duty cycle of the PWM signal, the brightness of each LED module and the display effect of various colors can be adjusted.
[0048] Secondly, the signal modulation module integrates the effective level signals of the PWM signals controlling the R-LED module, G-LED module, and B-LED module with the high-frequency signals generated by the fixed frequency generation module to generate three corresponding wireless transmission signals, amplifies them, and then transmits them to the corresponding receiving resonant coil 9 via the transmitting resonant coil 3.
[0049] Finally, the receiving resonant coil receives the wireless transmission signal and generates electrical energy, which is then output to the corresponding R-LED module / G-LED module / B-LED module to power the lamp board 202. Simultaneously, the detection module of the lamp board 202 extracts the PWM signal from the wireless transmission signal, rectifies and shapes it into a corresponding PWM signal, and outputs it to the corresponding R-LED module / G-LED module / B-LED module to drive them to perform variable light emission.
[0050] This invention provides a wirelessly driven lighting fixture. The transmitting resonant coil 3 receives the wireless transmission signal and generates a fixed-frequency electromagnetic field and a signal electromagnetic field. The receiving resonant coil 9 utilizes near-field transmission characteristics to receive the fixed-frequency electromagnetic field and convert it into electrical energy. This electrical energy, after rectification and filtering, is output to an R-LED module, G-LED module, or B-LED group electrically connected to the corresponding receiving resonant coil 9 for power supply. The receiving resonant coil 9 also utilizes near-field transmission characteristics to receive the fixed-frequency signal electromagnetic field and convert it into signal electrical energy. A detection module extracts the PWM signal from the wireless transmission signal carried in this signal electrical energy and outputs it to the corresponding R-LED module, G-LED module, or B-LED module to control the brightness and color of the R-LED module, G-LED module, or B-LED module.

[0054] The mounting base 11 extends outward from the outer periphery of the side near the disk base 101 to form a flange 113. When the mounting base 11 is sleeved on the outside of the base 102, the flange 113 abuts against the bottom of the disk base 101.
[0055] refer to Figure 12As shown, the inner side of the light-emitting surface of the lampshade 203 is provided with several ribs 2031; the ribs 2031 can guide the propagation direction of the light emitted by the lamp panel 202, so that the light is more evenly distributed in the space, and can also prevent glare, while increasing the structural stability of the lampshade 203.
