Abstract

A lighting system comprised of a central controller, a digital communications path, and a plurality of image projection lighting devices (IPLDs) is provided. The IPLDs contain cameras that can capture both visible light and infrared light. Address signals sent from the central controller first address a particular IPLD and then command signals sent from the central controller control an infrared blocking filter to be positioned in and out of a camera optical path of the particular addressed IPLD.

Claims

1. A stage lighting apparatus comprising:

a base;

a communications port;

a processor;

a memory which can be accessed by the processor to obtain content which can be used by the processor to control the stage lighting apparatus;

a lamp housing;

the lamp housing comprising;

a lamp,

a reflector;

a lens;

a plurality of actuators;

a plurality of color filter assemblies;

a plurality of light emitting diodes;

wherein the lamp housing is remotely positioned in relation to the base by a motor;

wherein the lamp, the reflector, the lens, the plurality of color filter assemblies and a first plurality of the plurality of actuators cooperate in response to control signals from the processor to vary a color parameter;

wherein the plurality of light emitting diodes cooperate in response to control signals from the processor to vary an auxiliary lamp control parameter;

wherein the lamp, the reflector, and the lens direct a first light for illumination of a stage;

wherein the plurality of light emitting diodes direct a second light for illumination of the stage;

and wherein a first command received by the communication port causes the processor to send control signals to vary the auxiliary control parameter.

2. The stage lighting apparatus of claim 1 wherein
