Abstract

The invention discloses a method for controlling an LED lamp. The LED lamp comprises an AC / DC converter, a single chip microcomputer, a warm white LED lamp string, a cool white LED lamp string, a red LED lamp string, a green LED lamp string, a blue LED lamp string LED light string, radio frequency module and remote control device that cooperates with the radio frequency module; 1. The blue LED light strings are electrically connected, and the single-chip microcomputer is electrically connected with the radio frequency module, the warm white LED light strings, the cool white LED light strings, the red LED light strings, the green LED light strings, and the blue LED light strings. The invention has the characteristics of effectively eliminating voltage drop and current drop.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a control method of an LED lamp that can effectively eliminate voltage drop and current drop. Background technique [0002] With the application and promotion of LED in the field of lighting, more and more applications appear in our daily life, such as adjusting the brightness of the light, adjusting the color temperature, and adjusting the color. [0003] Generally, the same-phase PWM is used for color mixing control for color temperature and color adjustment. The advantage is that the control method is simple and easy to implement. [0004] However, the same-phase PWM signal output will cause a serious drop in the input voltage, resulting in large ripple current and stroboscopic problems, and the power supply at the input end will enter overload protection, making the LED lights unable to work normally.
