GE Debuts Jet Engine-Inspired LED Bulbs

What do jet engines and LED light bulbs have in commonplace? They both can overheat without proper cooling mechanisms. however even as jet engines are incredibly effective at staying cool, LED technology is still in its infancy. So GE determined to stick jet engine cooling mechanisms internal LED bulbs. The result: a lightweight 1,500 lumen LED bulb that produces as a great deal mild as a 100 watt halogen bulb at the same time as the usage of a third of the electricity.

GE dual cool jets are very small micro-fluidic bellows-kind devices

that offer high-speed jets of air, which impinge on the LED warmth

sink. these jets of air increase the warmth transfer fee to more than

ten instances that of natural convection. The advanced cooling allows LED

operation at excessive pressure currents without losses in performance or

lifetime.

higher cooling mechanisms additionally decrease the amount of LED chips utilized in a bulb–which in flip, lowers the bulb’s cost and weight. “nowadays, the value of LEDs constitutes over seventy five% of the fee of the system,” says Mehmet Arik, a mechanical engineer and GE’s major investigator at the LED undertaking. “If we reduce the variety of LEDs, the cost will drop.”  Arik’s 1,500 lumen bulb is clearly 1/2 the size and weight of the six hundred lumen LED bulb to be had nowadays.

GE’s jet engine-stimulated technology isn’t geared up for commercialization–but. “We’ll have more reliability trying out in the coming months,” says Todd Alhart, a GE  international studies spokesman. “however that is a tech platform that might help some of LED products inside the future.”
