Concept of Sunlight type LED

Light that Reproduces Sunlight to the Fullest Extent - Sunlight type LED

Toyota Gosei has developed an LED that achieves exceptionally high color quality using proprietary technology, in order to add new value to LED light sources.

Faithfully Reproduces the Colors of Objects, Providing a Comfortable Light Space that is Gentle to People

Spectrum of sun


  • Morning Sun (5,000K)

  • Daylight (6,500K)

  • Evening (2,700K)

With our unique technology, we have succeeded in faithfully reproducing the spectrum emitted by the sun.

About the Emission Principle of Sunlight type LED

Developing LEDs that closely sunlight.

Color quality of Sunlight type LED

"Based on TM-30-15, we are pleased to introduce the characteristics of Sunlight type LED below for your reference."

Spectrum

It represents the distribution of the intensity of each wavelength
component when light is decomposed using a spectroscope or similar device.

Color fidelity

It is an indicator of the fidelity of color reproduction, quantitatively expressing the deviation in the appearance of color.
Rf: Average of 99 colors

Vividness(Rg)

The vividness as seen in sunlight or incandescent light is rated 100 points,
and the quality of light is evaluated.

  • Dull light scores less than 100 points.
  • Vivid light scores over 100 points

Direction of color shift

Color deviation and saturation are expressed graphically.

  • The graph overlaps when it is the same as sunlight.
  • The deficient part is a lack of color.

The Sunlight type LED was developed to aim a light source that more faithfully reproduces sunlight.

Suitable application

We believe that leveraging the characteristics of our product makes it an ideal light source for the following applications.

The unique characteristic of this product would be best lighting source for the applications below.
