The festive lantern driving system based on P L C-BUS technology of claim 4, wherein two timing capacitors are arranged on an interface of the L ED electric lamp connected to a PWM circuit, and the main control chip instructs the two timing capacitors to execute pulse work corresponding to BASE64 coding;
the two time sequence capacitors output corresponding pulses to the PWM circuit according to the BASE64 codes, so that the L ED lamp obtains a corresponding color modulation signal from the PWM circuit, and then performs color modulation.
6. The P L C-BUS technology-based festive lantern driving system of claim 5, wherein the wavelength analysis chip is built with a color spectrum, the wavelength analysis chip determines a corresponding color from the color spectrum according to the obtained color modulation signal, and then a L ED electric lamp is used for performing corresponding color illumination output.
7. The P L C-BUS technology-based festive lantern driving system of claim 6, wherein the collection component is a color sensor, and the color sensor outputs an ambient light signal to a wavelength analysis chip.
