Each LED control unit is comprised of a zener diode parallelly connected with LED working elements made of an LED and a serially connected current limiting resistor. The forward voltage drop of the zener diode closely approximates the desired working voltage of the LED loads, and thus each LED control unit plays the role of a voltage regulator. When voltage of an LED control unit is below the stabilized voltage of the zener diode, the brightness of LED is continuously adjustable. When an LED branch circuit is put under the control of a constant current control module, the current flowing through each LED can be stabilized. | 01-15-2015 |
