    Let talk about the LED driver, including digital drives and analog drives two types of digital driver digital circuit drivers, including digital dimming control, RGB full color changes. Analogue drive refers to the analog circuit drive, including AC constant current switching power supply, DC constant current control circuit. Drive circuit consists of electronic components, including semiconductor components, resistors, capacitors, inductors, these components have the service life, failure of any one device will cause the failure of the entire circuit may be some failure. LED life expectancy is 5-10 million hours, according to 50,000 hours count, one after another lit, nearly 6 years of life. Switching power supply life is difficult to reach 6 years, the sale of the switching power supply on the market warranty period is usually 2-3 years, up to 6 years warranty is the military-grade power supply, the price is usually 4-6 times the power supply, usually The lighting factory is unbearable. Therefore, LED lamps and lanterns of the problems for the drive circuit problems.
