LED Drivers are electrical circuits which are designed to drive light emitting diodes (LEDs) in lighting applications. LED Drivers provide constant current regulation, so that it can control the LED\'s current regardless of the voltage and other environmental factors. One example of an LED Driver is the LPF-60D-20, which is a specialized type of driver designed to interface with a PV module or power source, and provide a constant current to operate a LED light engine.

LPF-60D-20 Application Field

LPF-60D-20 is designed specifically for photovoltaic applications. It features wide input voltage range and embedded electronics to allow for DC dimming with a phase-cut dimmer or PWM dimming with a standard PWM dimmer. It is suitable for use with commercial, industrial, landscape, and other LED luminaires, and provides silent operation across its wide temperature range. It also has a low wattage standby design, so it does not waste power when the light is not in use.

LPF-60D-20 Working Principle

The LPF-60D-20 works by transforming the higher voltage and higher current from a DC photovoltaic (PV) module or power source, into a constant current output. This allows for a reliable operation of LED luminaires without the need to radically change the input voltage levels. This is done by utilizing constant current control circuitry, which senses the current of the LED light engine. This constant current circuitry ensures that the LED runnning voltage is automatically set.

When the current through the LED light engine is drawn, the output of the LPF-60D-20 will decrease and the unit will automatically detect the LED\'s current to ensure that the LED light engine is operating at its ideal running voltage. This allows the LED luminaires to be used with DC dimming and PWM dimming, as well as with regular AC dimmers, to allow for complete control over the intensity of the lighting.

Conclusion

The LED Driver LPF-60D-20 is specifically designed for Photovoltaic applications. Its wide input voltage range and constant current feature allow it to provide silent operation and low wattage standby design. The unit\'s built-in constant current control also enables it to detect and adjust the LED\'s running voltage for DC dimming and PWM dimming.
