[Text / high-tech LED reporter Gao Jinyu] In recent years, LED as a new energy-saving light source, triumphantly, a route to outdoor lighting applications. The LED indoor lighting market broke out to drive the accessories.
The LED driver is a power converter that converts the power supply to a specific voltage and current to drive the LEDs. It seems to be inconspicuous in the design of the entire lighting product, but it is extremely critical.
From November 25th to November 27th, 2013 Gaogong LED Lighting Exhibition was held in Guangzhou Poly World Trade Expo Center. Jingchen Electronics brought thyristor dimming power products to participate.

SCR dimming, direct serial connection of thyristor dimmer, no additional wiring, strong replacement, high efficiency of primary conversion. The disadvantage is that the compatibility is not strong, there may be flicker, and the color temperature has a small amount of drift. Bao Xiwen, manager of Jingchen Electronics Sales Department, said, “Although thyristor dimming has such shortcomings, it has so far been a cost-effective dimming method.”

Statistics show that the domestic LED driver power supply market in 2012 was 10.1 billion yuan, a year-on-year increase of 37%. It is expected that the market size of China's LED driver power supply will expand by billions in the next two years, and there will be a certain degree of breakthrough in technology, especially in the field of high-power LED driver power supply, driven by the strong demand for LED street lamps. May show a good growth trend.
In the face of the lucrative LED power market, Bao Xiwen also revealed his harassment. Bao Xiwen hopes that the unified standards of the industry will be introduced as soon as possible, so that standard products can be produced and scaled production to reduce costs.
Bao Xiwen told the senior engineer that at present, Jingchen Electronics has turned from customized products to standard products in outdoor power supply, because the single-channel constant current of street lamp power supply is the mainstream direction. In terms of indoor power supply, Jingchen Electronics has developed across the board. Since there is no unified standard and the industry has no stable development, it can only be customized.
