The Amazing Magical LED: Has It Really Been Fifty Years Already?

The Light Emitting Diode celebrated its 50th anniversary this year. It's easy to forget LEDs have been around for so long, especially as they've become ubiquitous as cheap, energy-efficient sources of light in comparatively recent times.

Take those Christmas lights, for example. LEDs have almost completely replaced the tungsten bulbs we gazed at as children, and for good reason - they're up to 90 per cent more efficient, don't get dangerously hot on our tinder-flammable Christmas trees, don't need to be troublesomely filled with inert gas, and can last for up to 100,000 hours each.

The LED has become one of the most important electronic components in modern technology. The market for general lighting by LEDs is expected to be worth $19.5bn this year and reach $31.4bn by 2017.

General lighting accounts for just 35 per cent of the total LED market, though, with mobile devices - such as smart phones and tabs - accounting for 30 per cent.
