GE Debuts Jet Engine-Inspired LED Bulbs

What do jet engines and LED light bulbs have in not unusual? They each can overheat with out proper cooling mechanisms. however while jet engines are notably powerful at staying cool, LED era remains in its infancy. So GE decided to stick jet engine cooling mechanisms inside LED bulbs. The end result: a lightweight 1,500 lumen LED bulb that produces as plenty light as a a hundred watt halogen bulb while the usage of a 3rd of the energy.

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

that offer high-velocity jets of air, which impinge on the LED warmness

sink. these jets of air increase the heat transfer price to extra than

ten times that of herbal convection. The advanced cooling permits LED

operation at excessive power currents without losses in efficiency or

lifetime.

higher cooling mechanisms also decrease the amount of LED chips used in a bulb–which in flip, lowers the bulb’s cost and weight. “nowadays, the fee of LEDs constitutes over seventy five% of the price of the system,” says Mehmet Arik, a mechanical engineer and GE’s major investigator at the LED assignment. “If we lessen the quantity of LEDs, the value will drop.”  Arik’s 1,500 lumen bulb is really half of the dimensions 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 greater reliability checking out in the coming months,” says Todd Alhart, a GE  international studies spokesman. “however that is a tech platform that would help some of LED merchandise in the destiny.”
