With the advent of high-power LED, general fluorescent or incandescent 5 to 7 times its luminous efficiency, energy-saving effect is very significant. Thus, the high-power LED has broad application prospects. Currently, a single high-power LED has 1W, 3W, 5W and 10W, has been heavily used 1W and 3W high power LEDs, multiple high-power LED series and parallel, the the combination output power reached 70W ~~ 100W. High-power LED with high luminous efficiency and energy-saving advantages, but inconsistent pipe pressure drop is the need to overcome the shortcomings. Second, poor temperature characteristics of the high-power LED. Tube current and luminous efficiency varies greatly with ...

The switching regulated power supply volume is small, light weight, high efficiency, the Regulator a wide range of safe and reliable, to be used in many electronic devices. However, like other circuits also exist some problems, such as the control circuit complexity, higher operating frequency be TV, radio, electromagnetic radiation interference to radio noise appears, TV noise points, even feedback interfere with other electronic devices work properly. 1 super audio interference oscillation problems The operating frequency switching regulated power supply is more than for 20-100kHz, is a super audio range. To a frequency corresponding to work as a switching regulator of the power supp...
