Tips:



Classification of LED driver by driving mode:

(1) the constant current

Constant current drive circuit of the output current is constant, and the output dc voltage is different as the size of the load resistance within a certain range, load resistance is small, the output voltage is low, the greater the load resistance, the higher the output voltage.

The constant current circuit is not afraid of load short circuit, but it is forbidden to load completely.

Constant current drive circuit driving LED is ideal, but relatively high price;

Note that the maximum load current and voltage value are used, which limits the number of leds used.LED Corn Bulb 60W E39

(2) stable voltage type

When the parameters in the stable circuit are determined, the output voltage is fixed and the output current varies with the load.

The stable circuit is not afraid of load opening, but it is strictly prohibited to short circuit.

To drive the LED with a stable driving circuit, each string needs to be added with the appropriate resistance to display the brightness average of each LED display.

The brightness will be affected by the voltage change in the rectifier.LED Corn Bulb 60W E39
