LED power supply is the guarantee of development.

In LED to shine at the same time, the LED drive power | stabilizer is the guarantee of the development of LED industry chain, LED power supply quality directly restrict the reliability of LED products, therefore, in the LED industry chain gradually perfect today, mature of LED drive power supply is also important. In terms of LED power supply enterprises, there will be a great increase in the growth of the power supply market of around 100W in 2017. The LED light source from around 100W is more cost-effective than the traditional lighting source, and the LED street lighting and landscape lighting market will soon form an industrial scale.
Because LED is a sensitive semiconductor device and has negative temperature characteristics, it needs to be stable working state and protection in the application process, thus generating the concept of drive. LED devices are nearly as demanding as the power supply, and leds, unlike ordinary incandescent bulbs, can connect to a 220V exchange. The LED is a low voltage drive of 2 ~ 3 volts. It is necessary to design complex transformation circuits and different LED lights with different power adaptors. Foreign clients in the international market for the LED drive power conversion efficiency, effective power, accuracy of constant current, the power life, electromagnetic compatibility requirements are very high, design a good power supply must be considering these factors, because of the role of power in the lamps and lanterns is as important as the heart of the people.
In 2017, despite the financial crisis impact on the world economy, Europe and the United States and other international markets, the demand for high power LED power supply is very big still, corresponding high-end LED products exports less affected by the financial crisis. LED application products output value of Chinese mainland in 2008 has more than 45 billion yuan RMB, the LED display screen | demonstration application of street lamp, LED full-color display devices, solar LED, landscape lighting, consumer electronics, backlight, signal, instruction is still the main application fields such as, but under the background of a boom in the mainland market, LED products quality good and bad are intermingled, the requirements of the chaos of the drive power, also is the main factor that LED enterprise reshuffle in recent months. Under the development trend of LED products in mainland China, there are several challenges for LED power supply enterprises. First, the overall life of the drive circuit, especially the life of the key devices such as capacitors in the high temperature
