Abstract
An apparatus for generating artificial light that closely simulates the intensity and spectrum of natural light and other dynamic light conditions. The apparatus includes a collection of light sources of various colors which are controlled by a computer. Attached to the computer is a sensor that measures the spectral qualities of the light produced by the light sources. The sensor sends this information to the computer which then adjusts the light sources to generate the desired light conditions.
