On March 22, 2025, the financial sector reported that the China National Intellectual Property Administration information showed that Shanghai Biaolang Lighting Appliance Co., Ltd. applied for a patent entitled "an intelligent control method and system for LED lights", with the publication number of CN 119653543 A and the application date of February 2025.

The patent abstract shows that this application relates to the field of intelligent control technology for LED lamps, specifically a method and system for intelligent control of LED lighting lamps. The method comprises: in the process of regulating the brightness of LED lighting lamps, a microcontroller with a timer input capture function captures PWM signals on the driving circuit of LED lighting lamps, calculates the PWM frequency and PWM duty cycle at each time, and obtains the digital voltage value of LED lighting lamps at each time; Calculate the smoothness of adjustment, average correlation factor, hysteresis effect, and feedback deviation of adjustment; The adjusted proportional coefficient in PID control algorithm is obtained; Adjust the duty cycle of PWM to regulate the brightness of LED lighting. This application can make the brightness adjustment of LED lighting smoother, more accurate, and stable, which is conducive to precise control of the brightness of LED lighting, improving the overall lighting effect and user experience.
