Improve the efficiency of the power LED lights do either constant current limiting control the power amplifier control or constant current power supply, 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, LED flexible light strip, and HV9910, such chips are fed from a high pressure, LED flexible light strip, it is easy to use, but the high-pressure feed, resulting in increased IC heat, because IC to withstand about 300V DC, as long as just a little current, even if a MA, 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. Pull-down resistor to take power, Baoji LED flexible light strip manufacturers, so that the loss in the resistance, about which they have lost a few tenths of watts it. LED LED practicality less power, brightness is low, should not be used alone, Baoji LED Strip wholesale, while multiple LED assembly designed a practical LED lighting will have broad application prospects. Lighting designer lighting objects and luminous flux according to the needs, determine the shape of the optical system of lighting, LED number and size of power; you can also design a number of LED light tube combined into a point light source, ring light source or a surface light source 'secondary light ', depending on the combination into the' secondary sources' to design lighting.
