Patent 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.
