LED Lighting Analysis Of The Driving Power Supply Problems
Oct 15, 2016

We call the LED driver, including digital and analog-driven two categories, digital drive refers to the digital circuit driver, including digital dimming control, RGB full-color changes and so on. Analog drive refers to the analog circuit driver, including AC constant current switching power supply, DC constant current control circuit. Drive circuit from the electronic components, including semiconductor components, resistors, capacitors, inductors, etc., these components have life, any failure of a device will lead to the failure of the entire circuit or part of the function failure. LED service life is 5-10 million hours, according to 50,000 hours count, continuous light, nearly 6 years of life. Switching power supply life is difficult to achieve 6 years, the market for the sale of switching power supply warranty period is generally 2-3 years to reach the 6-year warranty is the military-level power supply, the price is 4-6 times the normal power supply, the general Lamp factory is very difficult to accept. So the failure of LED lamps and lanterns for the drive circuit failure.
