New cooling technology for LED bulbs

Jet engines and LED bulbs do not seem to have anything in common except that they can overheat if not properly cooled.

However, while the jet engine has been designed with very efficient cooling mechanisms, the heat dissipation technology for LEDs is still only in the " apprentice " phase.

But this may soon change as General Electric (GE) electrical equipment maker is studying the application of cooling mechanisms used in jet engines for LED bulbs.

This technology not only helps LEDs reduce heat, increase lamp life, but can produce a larger light source while using energy levels of only one-third than when not using technology. This.

According to GE, the key to this cooling mechanism lies in a technology called " microfluidics ."

"GE's dual cooling system is a super-slim tube device that can produce high-speed jet streams and directly impact the heat dissipation of LEDs," explains GE.

Jet airflow increases the heat transfer rate by up to 10 times, thereby allowing the LED to operate at high currents without sacrificing performance or longevity.

In addition, the new cooling mechanism reduces the amount of LED chips used in a light bulb and as a result, the price and weight of the light is also reduced.

"The price of LED chips makes up 75% of the overall system cost, and if we reduce the number of LED chips, of course, the price will drop, " said Mehmet Arik, a GE project engineer and researcher. "

At present, this heat sink technology for LEDs is still in development and GE has not yet commercialized itself.
