NightScape Technology by Lumileds

NightScape technology, which minimises the blue component of LED modules, has won a Build Back Better PLATINUM Award in the 2023 lighting category. 

Blue light content is a critical factor as it has been shown to have a significant impact on the circadian rhythms and behaviours of humans, plants, and wildlife. It is increasingly the focus of attention for local authorities, municipalities, policy makers and legislators.

Communities across the world are grappling with how to reduce the impact of artificial light at night and municipalities and governments are addressing the issues of light pollution and wildlife impacts with lighting ordinances that proscribe both the design of light fixtures and the nature of the light that they emit. Some local authorities –such as Maui in Hawaii – even limit blue to under 2 per cent of new exterior light.

Designers often want warm colour temperatures of 3000K and 1800K for outdoor applications but these can still have relatively high percentages of blue light content and cannot come close to achieving less than 2 per cent. Phosphor-converted amber, or a 3000K white LED and an amber filter or amber optics are options, but both have significant downsides.

NightScape Technology is the first white light to significantly reduce the percentage of blue content between 400nm and 500nm to less than 2 per cent. It is now possible, thanks to this advanced LED technology, to start with the right light for night-time illumination.
The technology is available in Luxeon 3030 HE Plus and Luxeon 5050 Square LED emitters, two workhorses of the outdoor lighting industry. Over time, the technology can be applied to Lumileds’ full range of white LEDs.
These products with NightScape Technology will have a correlated colour temperature of 1850K and blue light content of just 1.8 per cent in the 400-500 nanometer range of the visible light spectrum.
