Not exactly "powered" by. You are still using electricity.
LED lighting is nothing all that new. I played with LED's over 30 years
ago. I remember seeing similar devices being used as night lights
over 20 years ago, and I know they have been using them in traffic
signals more and more over the last decade.
The question comes down to cost, which was not mentioned. How
much does it cost to buy, how much energy does it use to generate
the same light, and how often does it need to be replaced? Also,
does it generate light along the right frequencies. I know a number
of women that will not give up their bulb they use for vanity purposes
as well as the need to provide more "natural" lighting to the work
environment.
Light bulbs powered by smart chips

Say goodbye to the incandescent light bulb, LED chips will soon power the lights in our homes and offices. SmartPlanet goes behind the scenes at Bridgelux, to see how they're reinventing lighting with a brand new socket and bulb.

RE: Light bulbs powered by smart chips
As an engineer I detest sloppy reporting.
The credibility of this "anouncement" is undermined by incorrect terminology, clumbsy syntax and the lack of balance.
Lifetime, color balance, efficiency cost, both initial and lifetime, are glossed,over.
Yes, we will likely migrate to LEDs as light sources, but, it will happen when all parameters are factored in (unless politicians barge in where intelligent people fear to trod).

RE: Light bulbs powered by smart chips
I am typing this by the light of a 6 watt LED lamp over my dining table which provides about the same as a 40 watt tungsten filament bulb. I have to admit it's the only one I have, and the only reason I have it is that the Post Code Lottery in this country (Netherlands) dished one out to all subscribers. In the shops they cost around USD 25, so for the time being most people are switching over to fluorescent low energy lamps, which are a whole lot cheaper. However, I love it: the light's the right colour, it generates next to no heat (I can unscrew the bulb without waiting for it to cool down), and it starts instantly, unlike a fluorescent tube lamp.

RE: Light bulbs powered by smart chips
Why no button that takes me to website so I can see products?
What about cost? I bet the LED replacement for the 40watt bulb is not the same $0.80 the bulb costs!

RE: Light bulbs powered by smart chips
fdcampbell, for someone who detests sloppy reporting, you could improve your own spelling and grammar.
Meanwhile: The EU ban on incandescent bulbs was permature. Sure, they are inefficient if you look at the light output, but it is during the winter that they get most use ... when the heat is useful too, so no actual waste of energy. CFL's use Mercury ... something we should avoid. LED's still have a way to go before they will be an acceptable substitute anywhere other than in the most energy sensitive environments ... my houseboat being one of them, where I intend to keep to an absolute minimum, the appliances that consume anything other than 24VDC

RE: Light bulbs powered by smart chips
Because of the current high price of LED lamps, I need an easy way to get manufactures replace a defective LED lamp. Recently a CFL lamp that needed replacement within 2 months of use required me to send the original purchase receipt with the defective lamp to the manufacturer. Finding the instruction and address was itself a job and the cost of packing and postage was too high compared with the price of the lamp.

how much flicker is there in them....
Many people cannot use florescent or led lights so are they supposed to sit in the dark.

Not ready for real world
I bought a LED replacement for an incandescent at WalMart. Bought 3 incandescents for 1.50, one CFL for 3.00 and on LED for 10.00. The incandescents are still burning, while the LED failed in less than a month and the CFLs in less than a year. WalMart wouldn't take the LED back because I didn't have the original packaging. Plus one of the CFLs shattered while lit over my daughter's bed, so now I have to worry whether she inhaled mecury vapor. Bottom line, not ready, unless they've made dramatic improvements in the last year.

RE: Light bulbs powered by smart chips
Shane K: using filament bulbs as a supplemental source of heat is a wasteful use of energy.
70% of base energy is lost between generation & transmission.
It would be more efficient to generate heat locally rather than using electricity for heating.

Fluorescent more efficient than LEDs
Fluorescent lighting puts out more lumens per watt than LEDs. --
Thus, LEDs have a ways to go before I put them in my home to any
extent (except in flashlights). ---- Either way, incandescents are
generally out.

RE: Light bulbs powered by smart chips
Incandescent lamps still have their place. I'd like to see a CFL or LED lamp keep a water well pump from freezing on a cold winter night. I'd like to see a CFL flood lamp come on instantly in a security lighting application. I'd like to see an LED put out the same light level as an incandescent with the same efficiency -- which they don't, due to a phenomenon called "droop". Furthermore, there are improvements in incandescent filament technology now in the works that will boost their luminous efficiency to rival CFLs, with none of the toxic waste side effects.

RE: Light bulbs powered by smart chips
Some people seem much too critical of this subject - I agree that lighting needs have many factors, the color temperature, direction, quantity, etc - but this is exciting news!
Most of my bulbs in my condo are florescent - a few are incandescent - and I have a great LED bulb in a "snake light" that I can swivel around - to the left of my computer. Right now, florescent seems to have the most 'bang for the buck" - but LED prices are dropping.
Think of what really low electrical use bulbs mean for people in remote areas - with back-up generators, for example - remember the old mansions in the murder mysteries - where a broken electrical wire rendered the whole house into a - death trap? Those days may be gone forever with really efficient bulbs.
And does everyone have to pick on the grammar and stuff? You know what the gentleman is saying - powered by chips - could actually be correct, depending on what you mean by powered by - he didn't say the chips were creating the power.

Outstanding! I love any advancement that also addresses global warming and the lack of funds in my wallet these days. Thanks for posting this usefull article. Are these in the market yet or if not, when?

I can reduce the weight of the ligthing device in a 75% !
I have a development to reduce the weight of the lighting devices from 40% to 75% while maintaining a useful life of over 100,000 hours.Specially designed to work with smart chips . I am interested in contact with anyone knowing about it.

>>Sumi Das: This isn't your ordinary chip fabrication plant making processors for PCs. Instead these engineers are inventing a new kind of chip to power LED lights. Bill Watkins is the CEO of Bridgelux, an LED lighting chip manufacturer based in Livemore, California.
>>Bill Watkins: What we're able to do with a LED in a smartchip is give you the light that you really like and do it in a way that's energy efficient and then clean and green.
>>Sumi Das: From retail stores to residential homes LEDs hold the promise of better durability and a longer lasting light but more important they use less energy than a standard incandescent bulb. Bridgelux plans to lower consumption by using this chip and it comes with a new light socket.
>>What we really see as the future is something where you've got this great thermal interface, you've got a really slick electrical contact system and you got something that's mechanically sound. So, as this thing goes together you'll hear this distinctive click. So, this is the future of lighting.
>>Sumi Das: So, what does this mean for the millions of light fixtures currently in homes? Will they need to be retrofitted? Not necessarily.
>>What we do is we basically say "What can we do to emulate that traditional light source?" This, for example, is a 40 watt incandescent replacement and, you know, you can see there it is, light bulb.
>>Sumi Das: No new fixtures required and some definite energy savings on the way from these LED chips.
>>It's going to be a radical metamorphosis of this whole industry.
