Description

technical field [0001] The present application relates to the field of LED lamp control, in particular to an LED driving method and a driving circuit. Background technique [0002] Light Emitting Diodes (LED for short) are used as indicator lights in circuits and instruments, or to form text or numbers, and screen displays, and can also be used directly as a lighting source for practical use. According to the three primary colors of light - red, green and blue mixed in proportion, light-emitting diodes can synthesize colored light and realize the application of colored light. As a new type of light source, light-emitting diodes have the characteristics of energy saving, environmental protection, and high efficiency. This technology has matured and is widely used in various fields. [0003] The LED drive circuit is an important part of the LED lamp, which converts the electric energy obtained from the outside into a stable direct current to provide power for the LED lamp bea...
