Improve the efficiency of the power LED lights do either limiting constant current control power supply, LED lights, or constant current power amplifier control, power supply problems to be solved. That is, when the switching power supply chip work is to require a relatively stable DC voltage supply for the chip, the chip's operating current range from one to several MA MA. Like FSD200, NCP1012, and HV9910, such chips are fed from a high pressure, it is easy to use, but the high-pressure feed, resulting in increased IC heat, Jiuquan LED lights supplier because IC to withstand about 300V DC, Just just a little current, even if a MA, there are 0.3 watts consumption of the damage. General LED power but about ten watts, Jiuquan professional production of LED light bar, click on the loss of a few tenths of watts of power efficiency can be pulled down a few points. Typical like QX9910. Pull-down resistor to take power, Jiuquan LED light bar factory direct, so the loss in the resistance, about which they have lost a few tenths of watts it. LED Strip Light LED Flexible Strip Light, also known as LED strip light and LED lights, the English name called LED Strip, like the shape of the product as a strap, plus the original main product is LED. So called LED soft light with more. Jiuquan LED lights, Shenzhen far lighting (certified), LED light bar away from the Shenzhen Lighting Limited. Lighting Co., Ltd. Shenzhen far (www.zhenyuled.cn) (www.zhenyuanled.cn) is Xi'an, sodium leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In Shenzhen far lighting leadership with the staff warmly welcome all inquiries negotiations to create lighting Shenzhen far better future.
