When LED lighting meets aircraft engines

When LED lighting meets aircraft engines, although everyone agrees with the superiority of LEDs in terms of energy and lifespan, critics still think that LED lights are not bright enough. This is closely related to the heat dissipation problem of general LEDs. Inside this LED lamp, there are two small bellows-type devices that drive high-speed air jets, and the generated airflow impacts the built-in heat sink to achieve a cooling effect. They suck in air, and then eject the air from the same opening at a faster speed. In fact, they expand and contract to promote high-speed air flow. This idea is derived from the design principle of the surface airflow control system used in GE jet engines. The lumen prototype LED lamp developed by the U.S. Department of Energy and the University of Maryland can release the light equivalent to a watt halogen lamp, and only consumes/energy. What technology does it rely on to achieve such lighting efficiency? Answer: Originally used for GE aeroengines High-speed air jet technology.
