Spectral multi-channel LED light source
Goptica's spectral tunable multi-channel LED light source system is a simulator for achieving high-quality light sources. Output any color temperature light source with high color rendering index (CRI) and low metamerism index (MI). Under the premise of ensuring the same light quality, the spectral adjustable multi-channel LED light source system can achieve overall brightness adjustment and individual channel single-type LED brightness adjustment. The luminous intensity of each channel within the light source can be adjusted arbitrarily to freely design the required light source, providing adjustable wavelengths from ultraviolet, visible to infrared. With a lifespan several times longer than that of traditional fluorescent lamps, the elaborately designed heat dissipation system ensures the excellent stability of the light source.
