Liquid-Cooled LED Bulbs

By Rain Noe - January 18, 2012

As we saw with Jake Dyson's CSYS lamp, an integrated cooling system can enable LED bulbs to live longer lives. Now a company called Switch has encapsulated that principle in the very bulb itself—with liquid-cooled lightbulbs.

Switch claims that their bulbs, which are dimmable and can be screwed into any standard fixture, will last 25,000 hours and generate $150 in savings over their lifetime. (A good thing, as the $25-$35 price per bulb is bound to provide some sticker shock.) Unsurprisingly they're mum about how the liquid cooling technology works, but perhaps they'll release more information when the bulbs start shipping later this year.

no rocket scienctists died in the makin of this product ...

in high-voltage and hi amp electronics - cooling with liquids is quite common. one option is to run water trough heat sinks attached to the parts in question, or to put the whole stuff into a basin filled with oil and find a way to reduce the temp of the oilbath.

latter is used here and they are by far not the first who've dunnit with LED replacements.

the oil in the bulb simply transfers the heat from the LEDs to the heat sink at the bottom of the construction.
