Abstract
A lighting system and luminaire replicates attributes of natural sunlight and the sky. An array of light emitters capable of emitting light closely mimicking natural sunlight. This emitted light features an adjustable correlated color temperature (CCT) that spans from 1900 K to 6500 K, faithfully reproducing the Sun's appearance across different times of the day. To ensure precision in spectral matching, the system operates within a defined wavelength range of 400 nm to 1400 nm. At least one light emitter with a wavelength within the range of 760 nm to 1400 nm is incorporated to guarantee accurate representation. A luminaire equipped with a panel interacts with the multitude of light emitters, proficiently emitting color-tunable light and simulating diverse sky scenes. To facilitate control and customization, a dedicated control system is seamlessly integrated into the luminaire, enabling precise adjustment of the correlated color temperature and spectral power distribution.
