The constant flow regulation module 2 adjusts constant current value according to the quantity of the LED light group 4；
The antisurge module 3 plays antisurge pooling feature；
The quantity of the LED that the LED light group 4 is included be 28 and more than.
The rectification module 1 is full-bridge rectification module.
The LED used by the LED light group 4 is high-voltage LED lamp, and the running voltage of the high-voltage LED lamp is 3-9V.
Operationally, the LED of selection is high-voltage LED lamp, pressure for 3-9V, and the LED quantity that LED light group 4 is selected is
28 and more than, it is possible to the voltage for bearing is more than 250V, voltage 250V after the civil power 220V rectifications of just coincideing or so,
Civil power work can be directly inputted in the case of not external transformer.Meanwhile, in order to integrated circuit can be provided in LED light group
Electric current needed for 4, circuit add constant flow regulation module 2.
Constant current value is adjusted by choosing appropriate decompression capacitor C1 and constant flow regulation module 2, more preferable power supply can be reached
Efficiency.
Electric capacity C2 primarily serves antisurge effect, it is to avoid IC moments are breakdown, can improve the reliability of product.
