Driving power supply system of an active type LED with multiple channels

摘要

The present invention is to provide an active type multiple channeled LED power driving system, which is an operation system of driving power mainly designed for light source equipment using high power LED. The best system composition includes seven operation regions. The ordinary power is lead-in through a first region, and at first the regulating and filtering are proceeded by an EMC circuitry. Then, after it is lead-in a PWM circuitry to raise its power, the voltage transformation is processed through the second region. After it is further regulated and filtered to form the optimum power through the CC&CV control circuitry in the third region, it proceeds multiple channeled splitting by the fourth region. And, the original DC (direct current) power output is modulated into the intermittent electric power capable of controlling the output frequency and width of period by intermittent modulating circuitry in the fifth region. It further is output to the LED lighting modules of the sixth region to proceed the light source activation operation. At the same time, there is an environment parameters' sensor set in the seventh region to feedback the temperature coefficients of the LED lighting module to the CC&CV control circuitry in the third region to proceed the adjustment and judgment in its curve of output voltage and current. Through this, it can achieve the active electronic typed heat dissipation and raise the energy efficiency thus let the LED lamp and lantern be able to achieve its maximum performance.
