What is a constant current LED driver?

Constant current LED drivers maximize light output without over stressing the LEDs to provide consistent, even light. By controlling the maximum current going through the system, these LED drivers prevent thermal runaway. These drivers are required when the driver is used to power the LED load directly.

How do you choose a constant current LED driver?

When choosing a constant-current driver for an LED project, ensure that the current and voltage requirements of the LEDs are met. If LEDs are in a parallel configuration, add all current values while keeping the voltage range steady.

How do you drive high current LEDs?

The most efficient way to drive high-current LEDs is to use a DC-DC converter with current feedback. DC-DC converters are efficient power-conversion circuits that use passive, low-pass LC filters to smooth out switching action into constant voltages.

Is a LED driver the same as a transformer?

Electronic transformers work in a similar fashion to LED drivers, but they tend to allow for larger output power. In other words, long-length strips of LED lights may require a power supply in excess of 200 W, and since LED drivers may be limited in power output to 100 or 200 W, an electronic transformer may be needed.

Can constant current LEDs be dimmed?

Although both constant-current and constant-voltage drivers can be made with a dimming feature, not all LEDs are dimmable — and the ones that are capable of dimming must be used with the proper dimming technology (e.g., PWM or CCR).

Can LED drivers catch fire?

The worst thing that can happen is the LED Strip can get very hot* and begin to burn whatever it is fixed to, if it is a flammable surface such as timber, the outcome can be disastrous. At best the Strip can have LEDs fail due to poor voltage and current control.
