Abstract

The invention provides an active multi-channel LED power source drive system. The optimal layout of the whole system comprises seven operation sections; a power source is led in from the first section, and is rectified and filtered through an EMC circuit; the second section carries out voltage transformation processing on the power source after the power is adjusted and improved through a PWM circuit; then the fourth section shunts the power source through multiple channels after the optimal power is formed by the rectification and filtration of a constant-current voltage-stabilizing control circuit of the third section; an intermittent modulation circuit of the fifth section modulates the prior DC power supply output into intermittent electric power of which the output frequency and cycle width can be controlled; then the power source is output to an LED luminous module of the sixth section for light source starting operation; simultaneously, the seventh section is provided with an environmental parameter detector used for returning a temperature parameter of the LED luminous module to the constant-current voltage-stabilizing control circuit of the third section to adjust and judge an output voltage and current curve so as to achieve the aim of improving electronic heat dissipation rate and energy efficiency again.

Description

technical field [0001] The invention relates to an LED driving power supply system, in particular to an active multi-channel LED driving power supply system. Background technique [0002] Generally, there are three output modes of the driving power system of LED (light-emitting diode), one is CVMode (constant voltage mode), the other is CC Mode (constant current mode), and the last is CC&CV Mode (constant voltage / constant current coexistence mode). ), but none of the above power drivers can actively control the optimal working voltage and current point of the LED, and due to changes in climate temperature or poor heat dissipation design of LED lamps, it is easy to cause overheating of the LED when the ambient temperature cannot be controlled Unfavorable conditions will reduce the brightness and energy efficiency of the LED, and even cause the LED light-emitting module to burn out. [0003] figure 1 Shown is a schematic diagram of an existing LED drive power system using CC...
