Improve the efficiency of the power LED lights do either constant current limiting control the power amplifier control or constant current power supply, LED lights Tongchuan suppliers, should solve the power supply problem. 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, Tongchuan LED light bar manufacturers, such chips are fed from a high pressure, it is easy to use, but the high-pressure feed, LED light bar, resulting in increased IC heat, because IC to withstand about 300V DC, as long as just a little current, even if a MA, Tongchuan LED lights professional production, there are 0.3 watts consumption of the damage. General LED power but about ten watts, about to lose a few tenths of watts of power efficiency can pull down several points. Typical like QX9910. With pull-down resistor to take power, so the loss in the resistance, it has lost it about a few tenths of watts it. LED lights waterproof IP68 waterproof LED light bar technology: usually called a full-filling plastic water pipe or full pipe pumping plastic waterproof LED light strip is currently the highest waterproof rating, fully in water use. LED strip lighting _ _ Shenzhen far Tongchuan LED light strip away from the Shenzhen Lighting Limited. LED strip lighting _ _ Shenzhen far Tongchuan LED light strips are a far Lighting Co., Ltd., Shenzhen (www.zhenyuled.cn) (www.zhenyuanled.cn) this year introduced a new upgrade, the above picture is for reference only, please call this page or Tel picture on to obtain the latest information, contact: Li.
