![]() ![]() Overheating may be caused due to over current or over voltage, and this is exactly why these two parameters must be strictly regulated in any given LED driver circuit. ![]() The biggest enemy of LED is overheating, which can cause a thermal runaway situation in LEDs. This implies that an LED driver must feature a constant voltage and a constant current, ensuring that the LEDs are never subjected to abnormal voltage or current conditions, and they never burn or deteriorate overtime. Thus, we can also say that LED drivers are basically power supplies, specially designed to operate or illuminate LEDs through controlled parameters, so that the LEDs illuminate optimally without the risk of an over voltage or an over current. Since LEDs are vulnerable semiconductors devices, they must be driven using a regulated current and voltage power supply. An LED driver is an electronic circuit specially designed to drive or illuminate a set of LEDs safely through controlled current and voltage output, as per the specifications of the LEDs.
