A Bright Future For Mitsubishi

Mitsubishi Electric's New Lighting System Mimics Blue Skies, Sunrises and Sunsets

Mitsubishi Electric exhibited its new technology during CEATEC JAPAN 2018.

Mitsubishi Electric Corporation announced today that it has developed an indoor lighting technology that mimics the daily change of natural light from sunrise to blue sky to sunset.

The system, which consists of a thin panel and frame measuring less than 100mm, incorporates a proprietary edge-lit method that emits LED light from the side of the light panel to achieve highly natural light with the depth and colour of the sky.

Modern workplaces are being upgraded to create comfortable environments that stimulate and motivate employees. This includes the enhancement of lighting in offices that have darkened or covered windows or no windows altogether. Mitsubishi Electric's new system, unlike conventional LED lighting systems, produces highly natural light, including colours similar to those of sunrises and sunsets as well as blue skies, and creates a sense of depth to make indoor spaces feel larger and more open.

Main Features

1) Thin package produces light with depth and colours similar to real sky - Edge-lit panel emits LED light from the side to mimic the sky's Rayleigh scattering effect, which occurs when sunlight strikes atmospheric air molecules in the daytime and scatterings short-wavelength blue light more strongly than long-wavelength red light, making the sky appear blue when viewed from below. - Panel and frame thickness measure less than 100mm combined, comparable to an ordinary lighting fixture, for wide-ranging applications in offices and public facilities. Also, panels can be tiled to cover large ceilings. Wouldn't it be better to sit in your office in the basement, with a blue sky above you as if sitting in a park?

2) Replicates colours of blue sky and both sunrises and sunsets - LED light source colours are controlled automatically throughout the day to replicate daily transitions of natural light from sunrise to midday sunlight to sunset.

Future Developments

Going forward, Mitsubishi Electric will develop applications that provide pleasing natural-like light in offices, public facilities and other environments where natural light is limited or unavailable.

The envisaged timing of the commercial release will be announced later, but the potential scope of the technology could see it being widely adopted in environments like hospitals, basements, offices and subways. This seemingly simple technology could have a very bright future.
