Future of LED

[taiscici]

Looks like TLED will replace fluorescent lights soon. T5 will be history.

 

 

Royal Philips Electronics NV has shown off a new type of light it says is twice as efficient as fluorescent tubes and more than 10 times as efficient as a traditional light bulb.

 

The prototype LED light made by the Netherlands-based company uses power more efficiently than any other white-light lamp on the market, says Philips, claiming it can produce 200 lumens of brightness from one watt of power. A lumen is a measure of brightness as perceived by the human eye, a way to measure the total amount of visible light present. Lumens per watt is a measure of bulb efficiency — how well lamps can convert electrical power to visible light.

 

Today’s most commonly used lamps are fluorescent tube lights which produce about 100 lumens of visible light from one watt of electrical power. Traditional tungsten bulbs produce only 15 lumens from one watt.

 

LED bulbs are the most efficient bulbs available at present. But customer adoption has been slow, LED lamp manufacturers said recently, due to price and, to a certain extent, confusion about features.

 

Still, the science is progressing, and it is hoped that customers will follow.

 

At the core of Philips’s new prototype light, named the TLED, is an extremely efficient blue LED, the Lumileds InGaN LED. The blue LED won Philips the L Prize in 2011, a U.S. Department of Energy competition to redesign the common light bulb for maximum energy efficiency. To make the light white rather than blue, and so suitable for general use, Philips embarked on a second phase of engineering.

 

Philips announced the results Thursday, showing off a prototype that integrates the blue LED into a functioning, ready-for-market white-light lamp. Engineers matched one blue LED with a second coated in green phosphor and added a third, red, LED. Combined, the red, blue and green lights create white light, suitable for offices and even homes.

 

Lighting accounts for 12% of total electricity consumption in the U.S., according to the U.S. Energy Information Administration, so the potential savings from halving energy costs are large. The company expects the new bulb could be in use by 2015.

 

A press release from Philips estimated the savings its lamp could generate. “Given that fluorescent tubes account for more than 50% of the world’s total lighting, transitioning to LED will drive staggering energy and cost savings. In the United States, for example, fluorescent lights consume about 200 terawatt annually,” it said.

 

“If these lights were all replaced with 200 lumen per watt LEDs, the U.S. would use around 100 terawatt less energy – saving more than $12 billion and preventing around 60 million metric tons of carbon dioxide from being released into the atmosphere.”

 

The Philips TLED light is also cheaper to make and less bulky than fluorescent tubes.

Looks like it. But will takes a loooooong time before it totally fade out! I am guessing 10+ years!

The upfront costs is what will stop most businesses from adopting LED's as lights anytime soon.

By the time my T-5 fixture bites the dust, maybe they will lol. LEDs are expensive up front, and then in 1 year a better model will be out, you will get dirt for resale, and pay an arm and a leg for a new one.

 

The chinese fixtures may be the only way it's worthwhile at this point...

You don't need to replace the whole fixture just the t5 tubes with tled tubes so upfront cost should not be that bad.

That would be pretty sweet....

So it sounds like they're making LED arrays that fit into a T5 fixture? Like they can be run off the HV ballasts that drive most T5's? That would be interesting.

What interesting is they will be combining blue,red and green led to make white light.

 

Here is the article with pictures.

Maybe you already knew this but here you go. Such "whites" have been available for a while for your tank:

LEDGroupBuy calls them Ocean Coral White, that all of the full spectrum LED lighting nerds are going on about.

 

White can be made by Blue-Yellow, like in the standard white LEDs but also by Red-Cyan or by Green-Magenta, apparently. Or by RGB.

Yes I just added a multichip rgb to my led built and it looks amazing.

 

This is interesting because maybe they can create a full spectrum for reef tank from just one tled bulb.
