Active cooling for compact high-power LEDs

active cooling

Active cooling concepts for LEDs.

With high visible light, low radiant energy, and no infrared or ultraviolet market today. While as much as 80 % more energy efficient than traditional incandescent lighting, LED components still create a considerable amount of heat.

High temperatures can weaken the lumen output, the color quality and the lifespan of an LED light.

By dissipating the heat emitted by the LED light source, the efficiency and length of life of the light source can increase exponentially. For high-lumen output applications, passive cooling is not enough. In order to reach the desired lumen values in a small form factor, active cooling is the perfect solution to effectively disperse the heat produced by LED components. Active cooling solutions are a new contender in LED thermal management systems. Dissipating heat directly from the core of the modules allows for less thermal resistance, making the entire assembly more efficient. Active cooling technology offers thermal capabilities that are superior to passive heat sinks and can raise performance while significantly reducing the size of the lighting fixture. With industryleading German-engineered compact fans, ebm-papst can provide the perfect cooling solution for your LED application. One of the most significant advantages that ebm-papst fans have on the life of the LED light is due to the reliability of our products. With active cooling solutions far surpassing the 50,000+ hour promise the industry is accustomed to, an ebm-papst fan is now the LED light’s most efficient cooling source.

Alongside passive cooling methods involving the use of bulky heat sinks with their limited potential in confined spaces, active cooling concepts offer major advantages and have a positive effect on output as well as saving space and enabling the desired service life to be achieved.
