Toshiba introduces new high luminous flux white LEDs

New package design, high-efficient, high-output and high-color rendering models, Toshiba lanuched its new series of LEDs. These LEDs are small but high luminous efficiency, and can be used as light sources for a variety of lighting applications, for example, the replacement lamps, architectural lighting, retail display, commercial/industrial, outdoor and residential lighting.

The new white LED down light products are put into a very thin package for the purpose of small equipment installation, having a long lifespan because of its low thermal resitance and can provide a ligh level of effeciency at 120 lm/W. Also, the special package structure makes the products suitable for lighting large areas.

Features include: Luminous efficiency up to 120 lm/W. (1-watt type) ; One of the industry's thinnest packages for 1-watt white LEDs; Package size: length: 3.1 mm; width: 3.8 mm; height: 0.65 mm; wide directional characteristics: 130 degrees to 140 degrees (typ.) ; Color variation: 6500 to 3000 K (this chromaticity range is compliant with ANSI C78.377); High color rendering models close to natural light; Support for lighting applications with the following requirements: 40 kh@Tj=80 degrees C; 70 percent survival rate. http://www.imigyled.com/index.html

From Toshiba's press release -

"The E‐Core™ line along with E‐Core™ prototype technologies for the global market, which include the

lighting industry’s brightest LED products, will be unveiled at LIGHTFAIR® International, May 12‐14 in Las

Vegas"

http://www.toshiba.com/lighting/data/news/news_41.pdf

 

These would seem to be aimed at being used as an array for lighting purposes as it seems their induvidual output is possibly not that high. 

 

120lm/W isn't half bad though from there 1W emiter (assuming fV of 3.5V that would be 120lm @ 285ma) , we'll have to see what the package is like.

Let's turn that spam into a post! Silly

Hopefully individual output is high and they will give Cree a run for their money.

That kind of competition would be good for us budget-oriented folks, maybe the Cree emitters will drop some in price.

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

No, it's not. That's pretty much the same as an XP-G (if not slightly better)

sb56637 is a lot more patient about this kind of thing than I would be.  This is Foy dailing back the ass-hole-o-response machine.

Everybody here is so positive and nice - Foy must step up and do the same.

XPG S2 does 141 lumens a watt.

Don't forget how excited everyone was when Cree first came out and the initial lumens-to-watt ratio were nothing we would consider exciting today.

So if Toshiba's first offering with the new LEd is somewhere between the XR-E and the Xp-G, who knows where it will be in a year or two? Competition is good, we will all benefit if there is an emitter out there that can be as bright as a Cree but can be mass produced  more cheaply.

You do realize how Cheap crees are? And if this is a Toshiba prototype, then I guess that Cree gets 231 lumens a watt...http://technews.tmcnet.com/news/2011/05/09/5496319.htm

120lm/w is in the region of what a XP-G does, sure not in it's best available bin but we don't know at this point how Toshiba operate. They may throw out fanciful figure like Cree seems to or they may be conservative.

Cree had press releases talking about products (not just lab experimetns) with numbers very close to this in 2009.  Shipping dates and costs to end users are the big questions.

The Toshiba does nothing for me but this link does. 231 lumens @ one watt while at 4500K. Say good bye to blue tinted LED's if you want uber-bright. Thanks for posting srfreddy. Could this be Cree's answer to the SST-90 or possibly for use in home lighting? Its to bad that these are only lab results at this time. I remember when Cree announced XR-E's that put out an incredible about of lumens in the lab but never made it into production. Time will tell what awaits us...

I'd say for almost all uses the XM-L is already better than the SST-90. There aren't many applications where a cluster of more efficient LED's can't do the job of one less efficient but brighter LED, flashlight are on the whole one of those exceptions. Most static lighting would be improved by dispersing the light source anyway.

 

As for us, we'll just have to wait and see if this turns into a real product...or in deed if it's efficiency can be scaled up to high power levels.

I bet, in a couple of months or so we'd start getting better bulbs from Toshiba. Aren't they known for being great innovators?

Hope they keep the prices close to Cree offering. Japanese stuffs had always been expensive.
