LED Drivers

LEDs rule today’s lighting sphere. Although it may seem that LED technology is a “new” thing, back in 1907 Henry Joseph Round was the first to notice that when a potential of 10V is applied to a special kind crystal, it emits yellowish light. Since then, the technology evolved and it became available to everyone.

But, what lights up LEDs? The answer is LED drivers. In simple terms, LED drivers give life (and energy) to LED bulbs. Since the high voltage ranges from 120 to 277V and the bulbs need low AC voltage, LED drivers actually convert the mains and provide the amount of required power as well as protection from surges and other power disturbances. If there were no drivers, the LEDs would become hot and unstable, and their lifespan would be significantly shorter.

There are two types of LED drivers, internal and external. Internal ones are mostly used in households while the external ones are used for outdoor and commercial applications. Some of the drivers even provide dimming and color sequencing, depending on their specifications. 

Modern devices can provide large power outputs capable of powering entire buildings handling immense amounts of heat and energy.
