LEDs for cyclists - a great idea!!!

A PhD student in Colorado has come up with a cool idea to help all those cyclists stop getting knocked down. Using LEDs Leah Buechley has woven in indicators and controls into a fabric jacket. The application of the LED technology Leah has developed dosen’t stop with cyclists though.

Earth-friendly lighting … LEDs #2 tio

Yet more proof that LEDs are the future for lighting in the home … this time coming from MercuryNew.com curtisory of those happyt guys over at TreeHugger.com. The tip we’re interested in says:

2. Get the LEDs out: LEDs, or light-emitting diodes, are extremely energy-efficient and long-lasting light bulbs. They cost more than CFLs, but use less energy and last longer. An LED light bulb can reduce energy consumption by 80 to 90 percent and last around 100,000 hours.

BMW 5 series using LEDs

To readers of this blog it will come as no surprise to see more and more car manufacturers switching to use LED. LEDS are flexible and can be put into clusters to create interesting and innovative designs.

BMW has been using LEDs more and more in their cars and I think they look great … it is a shame that more cars aren’t being factory fitted with LED technology, but that’s only a matter of time.

Health Issues of Low-Energy Bulbs - Reports Unscientific

In recent weeks the BBC has been reporting that Low-Energy bulbs are linked with health issues.  However you might be intrested to know that an article on http://www.banthebulb.org 

Dear BBC, I am very disappointed that you have not asked for any peer-reviewed science to support the claims that compact fluorescent lamps (CFLs) “worsen rashes” or “cause migraines“.  … It is well known that migraines can be caused by stress, food and daylight, so saying that CFLs are responsible for light-sensitive medical conditions, while ignoring all of the other everyday triggers is a significant claim to make and grossly unscientific. … Similarly, the claims that rashes are worsened by CFLs assumes that someone is using very outdated fluorescent tubes.
Dr Matt Prescott, Director, Ban The Bulb

You can read the full text of the comments Matt sent to the BBC on his website: “Migraines, rashes, peer-reviewed science?” 5th Jan 2008, banthebulb.org

I would expect Matt to updating his website when he get’s a reply from the BBC.

On a “GOING GREEN’ note, Matt made one other comment that was very interesting, carbon foot print related: “The UK’s ban of incandescents will reduce annual carbon dioxide emissions by 2-3 million tonnes“.

it’s been an LED christmas and new year

This year it’s been hard not to notice the switch from traditional bulbs to LEDs.   

 UNITY Christmas light display in Regent Street London

This Christmas, seeing in Christmas we’ve got large professional ministrations of LEDs on Regent Street, London.  Called UNITY the LEDs were arranged into clusters with a large central sphere, with 24 smaller spheres around it. The LEDs can glow at different intestacies and in different colours. They used motion detection to respond to what is happening on the street below. For example as people pass by sphere can light up. The LEDs are using a tenth of the electricity of previous installations.

Seeing us into the New Year in the USA we have the Times Square New Year’s Eve Ball.

New York New Year LED Ball!

The new ball with be watched by over one billions people watching world wide.

As a side note, The first “time-ball” was installed atop England’s Royal Observatory at Greenwich in 1833. This ball would drop at one o’clock every afternoon, allowing the captains of nearby ships to precisely set their chronometers.

This is the 100th celebration of the time ball, with the first being dropped in 1807. Only two years were missed out in that time, and that was due to “dimout” restrictions during the 2nd world war. The new 6ft (1.8m) ball is covered with 9,576 LEDs that use the same amount of electricity as 10 toasters. 

The main advantages

  • New technology will “make the ball glow like nothing else”, Tim Tompkins, president of the Times Square Alliance
  • Energy efficient lights
  • Twice as bright
