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

Giant LED Tetris for christmas anyone?

Giant LED Tetris for christmas anyone?

There can’t be many people left in the world who have not at one time or another played a game of Tetris but how about a GIANT game of Tetris in LED heaven? Well a number of guys based in the USA got together to make an LED based version of the game.

The ‘game’ is composed of 240 led buttons. If you want to move the Tetris block right/left, you simply touch a button left or right of the current piece. To rotate a block you touch a button in one of the top two rows. And to drop a block you touch the bottom row. It’s a hands on Tetris game! Now for a few  facts from the project:

  • 16 microcontrollers
  • Total of 256 MIPS
  • 720 LEDs
  • 1.5A current draw
  • 1300 lines of code
  • 28800 bits being updated per second

future glimpse

BBC RADIO 4, Science, The Material World

Yet another step forward in LED technology is being made. The new generation of LED bulbs will not only light our homes and offices but could also be used to keep data safe and purify water!

These advances were discussed in an interview with Dr Rachel Oliver during the BBC Radio 4 programme The Material World (6th Dec 2007). Dr Oliver is an LED researcher from the University of Cambridge.

LEDs have enormous benefits over standard light bulbs because they’re a great deal more efficient, come in a range of different colours and have a very long lifetime. They are also good at saving energy too.

Because they last such a long time, architects could cover the side of a building with exciting lighting effects without worrying about constantly replacing the bulbs.

The interview continued to go into depth with a discussion on the colour properties of current and future LEDs.

We’re aiming for white light that looks like sunshine, and there are scientists trying to mix phosphors in just the right proportions. If we can achieve this, the white will not only look warmer, but could also be useful for people with Seasonal Affective Disorder (SAD).

At UltraLEDs we have many years of experience of working with LEDs and are constently searching the globe for the best LED products. You can view out latest products via this link http://www.ultraleds.co.uk/products_new.php

Go GREEN - More or Improve

If you go into the News Agents remember have a look at the latest MOVE OR IMPROVE magazine.  With WINTER upon us it’s a great time to think about your lighting requirements. Switching to LED technology can SAVE MONEY and help to SAVE THE ENVIRONMENT at the same time.

From recent experience it can also be a great safety device.  I recently helped a friend change over to LED bulbs in their Kitchen. While removing one particular bulb it became evident that the bulb had been touching some fabric. Upon close inspection it was obvious that the fabric had nearly caught fire. While this is an extreme example … it clearly illustrates the benefits of LEDs which radiate little heat vs. TRADITIONAL BULBS  which radiate as much as 90% to 95% of their energy as heat.
