MULTI-EMITTER LIGHTING SYSTEM WITH CALCULATED DRIVE
First Claim
Patent Images
1. A lighting fixture comprising:
- a plurality of emitters, each of the emitters having an emission spectrum that differs from the emission spectra of the other emitters;
a driver circuit connected to the emitters; and
a controller that calculates drive levels for the emitters and informs the driver circuit to apply the drive levels to the emitters.

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. A lighting fixture can use information such as the illumination data, emitter age, temperature, and calibration data to calculate drive levels as needed to control intensities of individual emitters and thereby produce desired patterns of spectral content and time variation.
