| Video Discription | High Power Light Emitting Diodes have different requirements that need to be met when compared to regular LEDs. This guide will provide all the knowledge to power whatever High Powered LED you come across but will focus on 3W Aluminum Backed Star LEDs.

We will figure out and select the right gauge of wire, manage heat dissipation and the power requirements using the Datasheets. This way we can select the correct electrical componentry. LEDs are incredible pieces of modern technology, the real unsung heroes in our electronics world, but they do need to be utilised correctly to take advantage of not only their incredible brightness but their long lifespan as well. LEDs are unlike other traditional incandescent lights where higher voltages produce brighter light. The amount of light (Lumens) an LED emits depends on how much current is supplied. High-power LEDs can commonly take currents from 350mA to 3000mA. Too much current will result in thermal runaway and broken LEDs. Now most power supplies are made to regulate voltage, not current. If you connected a standard DC voltage regulated power supply to a line of LEDs it would provide too much current to the LEDs and cause them to break. Just remember that LEDs are greedy for current and need somebody to supervise them otherwise they will become gluttons and die a very early life. This is why we need a Constant Current LED Driver between the DC power supply and the LEDs. This acts as the supervisor. The LED driver can regulate the current and voltage provided to the LEDs so that they are always at the perfect level. A buck-boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage. The technology of buck, boost, and buck-boost (Step Down or Step Up) converters are utilized around the world to provide regulated low-voltage DC/DC power in nearly every electronics market. Importantly these devices manage and prevent excess current flow. If the voltage and current from the chosen power supply are too high for the LEDs you will need a buck (step-down) converter. If voltage and current from the power supply are too low for the LEDs you will need a boost (step-up) converter.
