1. A process comprising:
- producing first illumination data that represents a first spectral distribution; and
operating a first light source containing a plurality of emitters so that respective intensities of light from the emitters are determined from the first illumination data and a combination of the respective intensities of the emitters produces the first spectral distribution.

Abstract
Systems and methods permit use of efficient solid state emitters for broad spectrum continuous spectrum lighting defined by illumination data. The illumination data, which can be sold as a commercial product, can be recorded or authored and include spectral, temporal, and spatial information. Intensities of individual emitters such as LEDs can be controlled through a combination of pulse width modulation (PWM) and amplitude modulation (AM) of drive currents. The combination of PWM and AM permits fine tuning of the spectrum of emissions and creation of free space optical data channels.

13. A system comprising:
-
a first light source comprising a plurality of emitters, wherein each of the emitters has an emission spectrum that differs from the emission spectra of the other emitters; and a player connected to independently control the intensity of light emitted from each of the emitters, the player being capable of accessing illumination data representing a spectral distribution and in response to accessed illumination data, operating the emitters at respective intensities such that a combination of the respective intensities of the emitters produces the spectral distribution represented by the accessed illumination data. - View Dependent Claims (14, 15, 16, 17)
