System, redundant circuit and method for driving light emitting diode
2006
The invention relates to a light emitting diode (LED) driving system and the method thereo for driving a light emitting diode shine continuously and steadily. The invention is mainly formed by that a direct current voltage source circuit supplies direct current power source to the light emitting diode. By a constant-voltage and constant-current regulator, an alternating current power source comprising a domestic power source is used efficiently, the light emitting diode is driven to shine continuously with constant power, and a plurality of light emitting diodes can still be driven by one driver for keeping the equal constant power.
