When it comes to managing the thermal output of LEDs, there are three main options to combat the heat. If the heat isn't removed from the LED fixture, you run the risk of shortening the lifespan of both the lamps and the fixture, as well as reducing efficiency for higher utility costs than expected with LED fixtures. Here are the three ways to go about managing thermal output in LEDs:
Create a heat path
The first method is to create a heat path over the casing of the light where the junctions and contact pins are attached to the casing. While this is the easiest option, it is not the most effective course of action for long term cooling.
Cool the conductor paths
This method is where you cool the conductor paths on printed circuit boards to help eliminate the heat and move it away from the fixture. This is a good option that offers more long term viability, especially for fixtures that will receive a lot of use. This is done using a heat sink which is an add on item or may be part of the initial designs of the fixture. The heat sink pulls the heat away from the circuit board so the heat dissipates into the air rather than staying in the fixture itself.
Cool the metal cladding
The final option is to use the LED printed circuit board to cool the metal cladding on the LED fixture. This option also uses a heat sink component to pull heat out of the circuit board and into the air.
Now that you know a little bit more about the elements of heat from LEDs, as well as the best ways to manage that heat output, you can safeguard your LED fixtures to ensure a long-lasting life. LED is a great investment in any location because of the unique way LED cuts down on utility costs by way of maximum efficiency. With these tips on managing thermal output, make sure your fixtures last and perform the way they were intended for years to come.
