Realization and Experimental Characterizations by Schlieren Optics of an Ionic Wind Cooling System for High Power LEDs

LED lighting devices are today capable of replacing any light source, whatever its luminous power, with unequaled energy efficiency and a considerable lifespan. However, these are sensitive to heat, which is all the more important for high-power LEDs. The greater the power, the larger the heatsink. The active cooling device by ionic winds is a very energy and thermally efficient solution without audible noise. In addition, the addition of active ventilation makes it possible to reduce the size of the radiator considerably. This article presents the first experimental results with thermal and electrical characterizations according to the wind speed produced.
