Light Emitting Diodes (LEDs) are said to be several times more energy efficient than standard light bulbs but their structure and material traps light and reduces brightness, which makes them unsuitable as a domestic light source.
Dr Faiz Rahman, the researcher leading the project at the
‘As yet, LEDs have not been introduced as the standard lighting in homes because the process of making the holes is very time consuming and expensive. However, by using world-class facilities at the
‘LEDs not only use less power than current energy efficient light bulbs but they are much smaller and can last years without needing to be replaced. This means the days of the humble light-bulb could soon be over.’
The team of researchers use a technique called nano-imprint lithography to directly imprint the tiny holes onto the LEDs allowing more of the light to escape.
The project is being developed in conjunction with the
