Abstract

A multiparameter light is disclosed, which incorporates an LED (light emitting diode) tracking ring surrounding a main output lens. The LED tracking ring is capable of additive color mixing and in turn can simulate the color of the main projected light projecting from the main output aperture or output lens of the multiparameter light.

Claims (81)

1. A theatre lighting apparatus comprising:
