Isolation LED power supply series scheme.

Under the background of increasing global energy shortage and environmental protection requirement, all countries in the world are developing green energy-saving lighting. LED lighting, as a revolutionary energy-saving lighting technology, is developing rapidly. However, the demand for LED power supply is also increasing. High efficiency, high power factor, safety isolation, accord with EMI standard, high current control accuracy, high reliability, small volume, low cost are becoming the key evaluation indexes of LED power supply.
Specific requirements for LED power supply.
LED is a low-voltage luminescent device with long life, high luminous efficiency, safe and environmental protection, easy to use and so on. The isolation output is based on the requirement of safety specification. The higher the efficiency of LED power supply, the more efficient the LED will be, and the advantage of energy saving. At the same time high switching frequency, high efficiency makes the whole LED power supply easy to be installed in the design compact LED lamps. High constant flow accuracy ensures the brightness and color consistency of LED lighting in large quantities.
Below 10W power LED lamp cup application program.
At present, there is a wide range of power LED applications under 10W. Many one-piece products are available, namely, LED power supply and LED lamp are integrated in a lamp, which is convenient for users to use directly. Typical lighting specifications include GU10, E27, PAR30, etc.
