Artificial light in the quality of sunlight - SORAA full spectrum LED

SORAA full spectrum LED based on GaN to GaN Technology

Professor Shuji Nakamura is one of the founders of Soraa Inc. and was awarded the Nobel Prize for his research on the blue LED.
With the LEDs of the so-called VIVID series, Soraa has created full-spectrum LEDs that leave conventional light bulbs and halogen lamps far behind. Continue reading

SORAA Vivid full spectrum LED - natural light like from the sun

The sun is the measure of all things in terms of light

The quality of the sun's light and the colors it contains is decisive for human color perception.

You can't do more than the sun can provide - sunlight is best suited to naturally display or "render" all shades and nuances of color.

A triangle of glass - makes visible what is hidden in the white light

Visible white light contains all colors ?

A prism - a triangle made of glass - makes visible what is hidden in the white light.

If a narrow, neutral white beam of light is directed onto a prism made of glass or transparent plastic, the beam penetrates the prism and exits on the opposite side.
The path of the light beam is "bent" twice. Once when passing from the air into the transparent material of the prism and a second time when exiting the prism.
This refraction is caused by the sudden increase and decrease in density along the path of the light beam.
The air surrounding the prism has a lower density than the prism. Continue reading
