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 lighting apparatus comprising:

a lamp housing including a light valve and a main projection lamp;

a communications port for receiving address and command signals from a central controller;

a camera;

a visible light cut filter;

wherein the camera is capable of capturing visible and infrared images, and wherein the camera has an optical path;

wherein the visible light cut filter is located in the optical path of the camera;

wherein the visible light cut filter is controlled to be placed in or out of the camera optical path by one or more command signals received by the communication port;

wherein the main projection lamp has an optical path;

and wherein the position of the camera can be adjusted so that the optical path of the camera is adjusted with respect to the optical path of the main projection lamp.

2. The apparatus of claim 1 wherein

the camera can be adjusted so that the optical path of the camera is substantially aligned with respect to the optical path of the main projection lamp.

3. A lighting apparatus comprising:

a base housing;

a lamp housing including a lamp;

wherein the lamp housing can be positioned in relation to the base housing by a motor.

a communications port for receiving address and command signals from a controller;

a camera;

wherein the camera is capable of capturing images, and wherein the camera has an optical path;

wherein the camera has a position in relation to the lamp housing;

wherein the position of the camera in relation to the lamp housing is varied by a motor from a first position to a second position in response to a command from an operator of a control system.

4. The lighting apparatus of claim 3 wherein

the camera further comprises an infrared cut filter.

5. The lighting apparatus of claim 3 wherein

the camera further comprises a visible light cut filter.

6. The lighting apparatus of claim 3 wherein

the command is compliant with DMX protocol.

7. A method comprising:

locating a visible light cut filter in an optical path of a camera;

controlling the visible light cut filter to be placed in or out of the optical path of the camera by one or more command signals received by a communications port from a central controller;

adjusting a position of the camera so that the optical path of the camera is adjusted with respect to an optical path of a main projection lamp of a lamp housing;

and wherein the camera is capable of capturing visible and infrared images.

8. The method of claim 7 further comprising

adjusting the position of the camera so that the optical path of the camera is substantially aligned with respect to the optical path of the main projection lamp of the lamp housing.

9. A method comprising

a communications port for receiving address and command signals from a controller;

a camera;

varying a position of a camera in relation to a lamp housing by a motor from a first position to a second position in response to a command from an operator of a control system;

positioning the lamp housing in relation to a base housing by a motor;

wherein the lamp housing includes a lamp;

wherein the camera is capable of capturing images, and wherein the camera has an optical path;

and wherein the command is received at a communications port.

10. The method of claim 9 wherein

the camera includes an infrared cut filter.

11. The method of claim 9 wherein

the camera includes a visible light cut filter.

12. The method of claim 9 wherein

the command is compliant with DMX protocol.
