    Jet Engine Tech Keeps LEDs Cool, Just Ask GE

    Making the rounds this week is a GE press release on a new LED downlight that uses “jet engine technology” to enhance cooling and overall efficiency. GE engineers were able to leverage thermal management tech and knowledge gained from their Jet Engine research and apply it to LEDs.

    To achieve this efficiency GE is using small bellows within the heatsink that increase heat transfer “more than ten times that of natural convection”. Better heat transfer means less heat to the LEDs, which equals higher performance and fewer LEDs required. GE has called the bellows “dual cool jets”.

    As effective as the design may be, it’s much more simple than some writers have described. There are no moving parts or mini jet engine fans. We reached out to GE, who were quick to respond back to us and engage in dialogue on the design.

    Todd Arhart with GE Global Research described the dual cool jets as “active cooling without any rotating parts such as a fan”. He went on to say, “It’s technology we have patented in our labs, which leverages what we have learned from other cooling technologies that have been developed and applied to other GE products such as an aircraft engine.”

    The 1500 lumen light shown here is aimed to replace PAR38 halogens; in terms out luminous output, it’s already there. Using the dual cool jet bellows, GE was able to make this downlight half the size and weight of 600 lumen downlights that are currently available.
