1. A lighting fixture for producing a beam of light having a prescribed luminous flux spectrum, the lighting fixture comprising:
- a plurality of groups of light-emitting devices, each such group configured to emit light having a distinct luminous flux spectrum, and at least two of the plurality of groups including different quantities of devices; and
a controller configurable to supply selected amounts of electrical power to the plurality of groups of light-emitting devices, such that the groups cooperate to produce a composite beam of light having a prescribed luminous flux spectrum.

Abstract
The systems and methods described herein relate to LED systems capable of generating light, such as for illumination or display purposes. The light-emitting LEDs may be controlled by a processor to alter the brightness and/or color of the generated light, e.g., by using pulse-width modulated signals. Thus, the resulting illumination may be controlled by a computer program to provide complex, predesigned patterns of light in virtually any environment.
