What is the difference between a constant voltage and constant current driv A constant voltage driver regulates a specified output voltage. Designs using constant voltage supplies will need to regulate the current in their system. This can be advantageous in applications where the total number of LEDs for an installation is unknown or where added control is desired. A constant current driver regulates a specified output current. Designs using constant current are able to easily connect the driver’s output directly to LEDs without added regulation. This is possible because LEDs respond directly to the current driven through them.

What is LED? LEDs are light-emitting diodes, or electronic components that produce light by converting electrical energy directly to light by the movement of electrons within the material of the diode. Because LEDs are highly efficient, they are beginning to replace most conventional light sources

What are PF and PFC and why are they important to specifying LED driver Power Factor (abbreviated PF) is the ratio of real power to apparent power in an AC power system and is expressed as a number between 0 and 1Real power is the actual power drawn by the load whereas apparent power is the product of the load curent and oad voltage. Since the voltage andcurrent may be out of phase this product may be significantly greater than the real power.n order to maintain a gh power actor switch mode power sups( dng LED must m some om of power actor coection This is an important issue because a load with a low power factor draws more current than a load with a high power factor for the same amount ofreal power transfered. Low power actor therefore results in greater power sses in the utility ines. There are a number of standards now in effectrequiring certain levels of power factor correction in switch mode power supplies and/or LED drivers.
