A semiconductor proof-of-concept device is being presented in the Institute of Physics Publishing's journal Semiconductor Science and Technology, which may pave the way for the development of even more energy-efficient LEDs than those currently taking the lighting market by storm.
Technically speaking, the new device masterminded by researchers at Arizona State University emits red and green light separated by a bandwidth of 97 nanometres - larger than traditional semiconductors. The colours are emitted as lasers which makes the source more energy-efficient than traditional LEDs, eScienceNews.com reported.
Lead author of the study Professor Cun-Zheng Ning commented on the new technology: "In addition to being used for solid state lighting and full color displays, such technology can also be used as light sources for fluorescence bio and chemical detection."
Such a development is yet another example of how time and money being invested in lighting technology is seeing continuous newer and improved solutions to outdated, energy-guzzling lighting being designed, proving that there really is no excuse to waste money on excessive bills and unnecessary power consumption nowadays.
LEDs are somewhat taking over the lighting market as more and more people recognise the enormous benefits to be reaped by making the switch from incandescent and compact fluorescent solutions to new LED units.
Not only do they consume up to 50 per cent less power than their outdated siblings - slashing bills and emissions - but they boast a far superior longevity, which further cuts maintenance costs as the bulbs seldom need to be replaced.
Furthermore, the quality of light can be far better. For example, if you currently have numerous unsightly fittings marring the facade of your home, it may be time to invest in a newer, more energy-efficient outdoor lighting solution. A couple of new porch lights could not only enhance the quality of light outside your property, but it may also give it an aesthetic facelift for the summer months.
