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

摘要

An active type multiple channeled LED power driving system which includes seven regions, wherein power is lead-in through the first region with the EMC circuitry and the PWM circuitry, passing through the second region with the transformer, entering the third region with the CC & CV control circuitry, passing through the fourth region with two multiple channeled outputers, lead-in the fifth region having two intermittent modulating circuitries, outputting to the sixth region with the two LED lighting modules, and setting with environment parameters sensors in the seventh region, thereby raising the electronic typed heat dissipation rate and energy efficiency under the system operation to let the LED lamp be able to achieve its maximum performance.
