1. An apparatus for generating artificial light that mimics a desired dynamic light condition, comprising:
- (a) multiple illumination sources emitting light of different wavelengths;
(b) means for detecting spectral characteristics of the sum of said emitted light and transmitting said characteristics to a computer; and
(c) means for sending control signals from said computer to said illumination sources to control the intensity of illumination from a plurality of said illumination sources to alter said spectral characteristics so that the light mimics the desired dynamic light condition over time.

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.
