LEDs, or light-emitting
diodes, are the fastest growing lighting solution on the planet, with many
thousands of people choosing them for their higher levels of efficiency and
their consistently bright light. Becoming increasingly popular, experts are
trying to hone the technology even further in order to get the very best
results out of these energy saving light bulbs.
Experts at Dundee University are taking up the challenge of enhancing the LED
market with a major European research project which aims to revolutionise
lighting all across the world.
The premise of the
project is to create a whole new generation of LED light bulbs which emit white light. They would be more
efficient than existing bulbs and other LEDs, and if they were successfully
developed in a way that would make them affordable for consumers and viable to
mass-produce, they could help to reduce global CO2 emissions and energy
consumption.
White LEDs currently have
an efficiency rating of around 25%. This is still higher than halogen and
incandescent bulbs, which expend the vast majority of their energy through
wasteful heat energy, but the percentages can be improved upon with this study.
The researchers in Dundee are aiming to create a white LED which would be
around 50%-60% efficient; a huge improvement and a quantum leap in the world of
energy saving lighting. Energy consumption for everyday users would be vastly
decreased, resulting in much smaller energy bills, and the eco-conscious
element of the bulbs means much less contribution to a person carbon footprint.
The new LEDs also offer users improved control over aspects such as brightness
and tone, which can be a unique selling point for purposes such as feature or
commercial lighting.
The research is just the
latest in a long-line of technology-enhancing projects regarding LED light
bulbs that are commencing or coming to fruition. One such LED bulb that has
recently been introduced, can even be controlled remotely via a smartphone app.
These so-called ‘intelligent’ light bulbs are entirely controlled through WiFi
systems. They can change colour at the touch of a button and the light levels
across the home can be controlled from this one handheld focal point. Many
companies are also undertaking research to make their bulbs brighter and more
efficient for less energy, paving the way for LED light bulbs to become
ubiquitous in years to come.
