DOE develops new LED lights using aero-engine air jet technology

The US Department of Energy (DOE) and the University of Maryland have developed a new type of LED light. The LED lamp has 1500 lumens to release the equivalent of a 100-watt halogen lamp and consumes only 1/3 of the energy. The product uses the high-speed air jet technology originally used in GE aero engines.

Despite the superiority of LEDs in terms of energy and longevity, there are still critics who believe 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 driving to generate high-speed air jets, and the generated airflow impacts the built-in heat sink to achieve cooling effect. They take in air and then eject air from the same opening at a faster rate, in effect promoting high-speed air flow through expansion and contraction. The idea came from the design principle of the surface airflow control system used in GE's jet engines.
