High efficiency solid-state light source and methods of use and manufacture
First Claim
1. A lighting fixture, comprising:
- an array of solid-state light emitters including at least two modules, each module having a module array of multiple light emitters on a substrate, the array mounted in a housing;
a transistor-based current source electrically coupled to the array of solid-state light emitters, the current source receiving power from a power supply and balancing DC current between light-emitters in each module array and among the module arrays; and
drive circuitry within the housing to control operation of the solid-state light emitters.

Abstract
A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.
