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 (100)

1. A theatrical lighting apparatus comprising

a housing;

a first lamp located within the housing;

a communications port;

a plurality of light emitting diodes forming a substantially circular array;

wherein the plurality of light emitting diodes emit a first light in response to a first command;

wherein a second light from the first lamp is emitted perpendicular to the substantially circular array of light emitting diodes;

wherein the second light from the first lamp is emitted from a location which is substantially centrally located with respect to the substantially circular array; and

wherein the first command is compliant with the DMX protocol.

2. The theatrical lighting apparatus of claim 1 wherein

the first lamp is a metal halide lamp.

3. The theatrical lighting apparatus of claim 1 wherein

the first lamp is a mercury lamp.

4. The theatrical lighting apparatus of claim 1 wherein

the first lamp is a xenon lamp.

5. The theatrical lighting apparatus of claim 1 wherein

the first lamp is a halogen lamp.

6. The theatrical lighting apparatus of claims 1 wherein

the second light emitted by the first lamp is remotely color varied using a CMY (cyan, magenta and yellow) color varying system.

7. The theatrical lighting apparatus of claims 1 wherein

the first light emitted the plurality of light emitting diodes is remotely color varied using an RGB (red, green, and blue) color varying system.

8. A theatrical lighting apparatus comprising

a housing;

a first lamp;

a second lamp;

a remotely controlled CMY (cyan, magenta and yellow) color varying system; and

a remotely controlled RGB (red, green, and blue) color varying system;

wherein the remotely controlled CMY color varying system is responsive to a central controller;

wherein the central controller includes an input device which can be used by an operator to individually adjust a cyan color saturation of a projected light from the first lamp;

wherein the central controller includes an input device which can be used by an operator to individually adjust a magenta color saturation of the projected light from the first lamp;

wherein the central controller includes an input device which can be used by an operator to individually adjust a yellow color saturation of the projected light from the first lamp;

wherein the remotely controlled RGB color varying system is responsive to the central controller;

wherein the central controller includes an input device which can be used by an operator to individually adjust a red color of a projected light from the second lamp;

wherein the central controller includes an input device which can be used by an operator to individually adjust a green color of the projected light from the second lamp; and

wherein the central controller includes an input device which can be used by an operator to individually adjust a blue color of the projected light from the second lamp.

9. The theatrical lighting apparatus of claim 8 wherein

the CMY and RGB color varying systems are remotely controlled by the central controller by commands compliant with the DMX protocol.

10. The theatrical lighting apparatus of claim 8 wherein

the RGB color varying system is comprised of a plurality of light emitting diodes, which include a plurality of red, green and blue light emitting diodes and the CMY color varying system is comprised of dichroic color filter media.

11. The theatrical lighting apparatus of claim 10 wherein

a first set of the plurality of red, green and blue light emitting diodes includes a first red light emitting diode, a first green light emitting diode, and a first blue light emitting diode;

and wherein the first set emits light through a single output aperture to create a homogenous color blend.

12. A theatre lighting apparatus comprising:

a base;

a communications port;

a processor;

a memory;

a lamp housing comprising:

a lamp,

a reflector;

a CMY (cyan, magenta and yellow) color varying system; and

a polymer fresnel output lens;

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

wherein the lamp, the reflector, the CMY (cyan, magenta and yellow) color varying system, and the polymer fresnel output lens cooperate to project a variable colored light; and

wherein a first command received by the communications port causes the CMY color varying system to vary the variable colored light into a first color; and

wherein the CMY color varying system is responsive to a central controller;

wherein the central controller includes an input device which can be used by an operator to individually adjust a cyan color saturation of a projected light from the lamp;

wherein the central controller includes an input device which can be used by an operator to individually adjust a magenta color saturation of the projected light from the lamp; and

wherein the central controller includes an input device which can be used by an operator to individually adjust a yellow color saturation of the projected light from the lamp.

13. The theatrical lighting apparatus of claim 12 wherein

the first command is compliant with DMX protocol.

14. The theatrical lighting apparatus of claim 12 further comprising

a gobo wheel for projecting patterns from the polymer fresnel output lens.

15. A theatre lighting apparatus comprising:

a base;

wherein patterns located by a gobo wheel can be projected by the polymer output lens;

wherein the color varying system is responsive to a central controller; and

wherein the central controller includes an input device which can be used by an operator to individually adjust a color of projected light from the lamp.

16. A theatre lighting apparatus comprising:

a base;

a communications port;

a processor;

a memory;

a lamp housing comprising

a lamp,

a reflector;

a color varying system;

a polymer output lens; and

an optical power varying system;

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