Constant current drivers use a feedback mechanism to adjust the current and match a reference value. They vary the voltage across the circuit to maintain a fixed current. This approach is essential for leds that need a specific output current.
A constant current driver provides a reliable current flow.
It prevents fluctuations that can damage your leds.
The driver keeps the brightness uniform across all leds.
Constant current drivers use a simple process to control the current:
The driver senses the current flowing through the led using a current-sensing element.
It compares the sensed current to a reference value.
If there is a difference, the driver adjusts the current to maintain stability.
A constant current driver alters the voltage throughout the circuit to keep the current steady. The voltage output changes, but the current remains fixed. This method avoids exceeding the maximum current specified by led manufacturers. You protect your leds from thermal runaway or burnout.
You should use constant current drivers for high-power leds or applications where consistent brightness matters. These drivers offer several benefits:
