1. a kind of super Large Copacity high-power LED driving power source, is exclusively used in 2-500W arbitrarily series connection reverse parallel connection LED lamp againIn, the LED-baseplate that great power LED list pearl chip has more than 1W, integration packaging has 20W, 30W, 50W etc.;

  • It is specialLevy and be, it is using existing electronic transformer, existing electric ballast constitute the power circuit, electric ballast both at home and abroad at presentIt is exactly electronic transformer circuit that circuit is slightly changed, and electronic transformer secondary coil output end high frequency square wave alternating current is used directly toAny reverse parallel connection combined high-power LED lamps again of connecting of connection 2-500W, for driving great power LED;

    Existing electronicsIn transformer, circuit of electronic ballast technical scheme, its main body circuit is by two triodes or metal-oxide-semiconductor, electric capacity and magneticThe high-frequency and high-voltage oscillating circuit of core coil composition, although oscillating circuit has several kinds of different connected modes, drives two three polesThe circuit of pipe or metal-oxide-semiconductor only has two kinds, and one kind is to use two current mode triodes of auto-excitation type Positive feedback coil coupling driving, itsIn again be divided into diac and the coil coupling drive circuit without diac;

    Another kind is to use special chip separate excitationFormula coupling driving metal-oxide-semiconductor, and special chip has a lot of kind descriptions, can be selected according to specific design use requirement;

    Buck is used directly to drive LED or Halogen lamp LED;

    Boost type can be commonly called as the rectification circuit conversion that silicon stack is constituted by high-voltage diodeIt is high voltage direct current, can is the DC plant of hundreds of volts or even tens of thousands of volts.
