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.
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?
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.
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.
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.
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.
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.
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.
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
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!
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.
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).
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.
