The output of LED driver power is mostly a constant current source that can change voltage with the change of LED forward voltage drop. In this video we will discuss how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver ampere control power supplies. Ensuring that the LEDs are never subjected to abnormal voltage or current conditions, and they never burn or deteriorate overtime. The biggest enemy of LED is overheating, which can cause a thermal runaway situation in LEDs. 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.
