What is Spectral Power Distribution (SPD) tunable technology?

Spectral Power Distribution (SPD) describes the energy distribution of a light source at different wavelengths and is the core parameter determining the color quality of a light source.
THOUSLITE‘s SPD tunable technology is achieved through the following methods:
• Using more than a dozen LEDs with different peak wavelengths as the light source
• Independently controlling the intensity of each LED channel through proprietary optimization algorithms
• Achieving precise adjustment of the output spectral power distribution
• Reproducing any measured or imported SPD, facilitating light communication between different locations
This means users can simulate any lighting scenario with a single device—from daylight to blackbody radiation, from laboratory standard light sources to specific commercial lighting environments.
