Core Technology

The Spectral Power Distribution (SPD) of traditional light source is fixed, as shown below, and only the light intensity can be adjusted.

Light quality parameters are the significantly important to evaluate the quality of the light source, and typical parameters includes color temperature, color rendering index, illuminance, glare index, uniformity, S/P value etc. THOUSLITE is proficient in a variety of light quality parameters theory, calculation, international standards, colorimetry, photometry, color measurement, etc. Meanwhile, THOUSLITE has the capability to customize parameters for different applications, such as special object color rendering index, museum lighting comfortness index, etc.

Light, object and observer are the three fundamental elements to generate human color vision.
