Efficiency test for point-source LED
NPL is helping Luminanz test the efficiency of a lighting concept that is 70 per cent more energy efficient than existing light bulbs.
An LED light fixture that diffuses like a normal bulb but directs beams only in areas where illumination is needed could brighten homes and businesses in the future.
The technology is being developed by Luminanz, a Bolton-based LED lighting company. The developers believe the new lighting concept - dubbed LED Luminaire - will be an energy-efficient replacement to current light bulbs and last 50 times longer.
It is claimed that the UK's carbon footprint could be cut by 43,000 tons a year if the technology were installed in just one million homes.
The Luminanz technology combines a light bulb and fitting into a single unit, which means the lighting would be sold within new fixtures.
In commercial settings, where lights are turned on all day, the upfront costs of buying new fixtures would be insignificant compared to the amount saved by not constantly replacing light bulbs, said Paul Miller, a research scientist at the National Physical Laboratory (NPL), which is testing efficiency of the lighting.
