Abstract

A light generating system comprising: a plurality of solid state emitters (SSEs) and a stability control system for controlling the spectral stability of the SSEs. In a particular case, the stability control system may comprise: a power regulator to regulate power supplied to a sub-set of the plurality of SSEs; a constant current circuit connected to the power regulator to provide a constant current to the sub-set of SSEs; a current regulation set point connected to the constant current circuit; and a controller configured to set the regulation set point based on metrology relating to the state of the SSEs.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 319,732, filed March 31, 2009, which is hereby incorporated by reference. technical field [0003] This document generally relates to a light generator and methods of operating and using the light generator. More specifically, this document relates to a light generator using solid-state emitters and having applications like a solar simulator. Background technique [0004] Light generators are devices used to generate various types of lighting conditions for various applications that may require specific brightness, spectrum, or other characteristics of light. Light generators can be used in a variety of applications including, but not limited to, evaluating and processing light-sensitive products, controlling photochemical reactions with high precision and versatility, and colorimetric testing. [0005] A specific application of light genera...
