LED driver circuit design circuit protection is an important part

In order to speed up the development of the LED industry, the Fujian Provincial Government issued a notice in May this year that the General Office of the People's Government of Fujian Province forwarded the Provincial Information Technology Bureau to issue certain measures for the promotion and application of LED lighting products in Fujian Province, which is planned to be completed before the end of 2015. Fujian Province has achieved widespread use of LED lighting products in the public lighting sector.

At the end of last year, the market predicted that the "big outbreak" of the LED industry officially kicked off in the third quarter of this year. In order to speed up the development of the LED industry, the Fujian Provincial Government issued a notice in May this year that the General Office of the People's Government of Fujian Province forwarded the Provincial Information Technology Bureau to issue certain measures for the promotion and application of LED lighting products in Fujian Province, which is planned to be completed before the end of 2015. Fujian Province has achieved widespread use of LED lighting products in the public lighting sector.

As the price decline of the products is more obvious, the price gap between products such as energy-saving lamps has gradually narrowed, and the consumer market has been further opened. Coupled with the government's vigorous procurement, since the end of last year, the sales performance of LED enterprises in Fujian Province has continued to rise, and the industry is gradually maturing.

At the same time of rapid development, the reliability of LEDs has also received more and more attention, and circuit protection is an important part of it. Since the LED power supply and the drive circuit are easily damaged by over-current shock and short-circuit faults, it is necessary to fully consider the protection measures of various fault states in the design of the drive circuit. This not only improves the reliability of the circuit, but also further reduces the repair rate.
