Abstract

An apparatus is provided including an image projection lighting device. The image projection lighting device may be comprised of a base housing, a yoke, and a lamp housing. The lamp housing may be comprised of a lamp and a first light valve. The image projection lighting device may be further comprised of a communications port, a processing system, and a memory. A cutoff value representing an amount of accumulated operating time at which the lamp may begin to operate improperly may be stored in the memory. An accumulated value representing an actual accumulated amount of operating time of the lamp may also be stored in the memory. The processing system may prevent the lamp from operating when the accumulated value is within a limit of the cutoff value, unless the processing system grants a request for a variance.

Claims

1. An apparatus comprising

an image projection lighting device comprising:

a base;

a yoke;

a lamp housing;

the lamp housing comprising

a lamp,

and a first light valve;

a communications port;

a processing system;

a memory;

wherein a cutoff value representing an amount of accumulated operating time at which the lamp begin to operate improperly is stored in the memory;

wherein an accumulated value representing an actual accumulated amount of operating time of the lamp is stored in the memory;

wherein the processing system prevents the lamp from operating when the accumulated value is within a limit of the cutoff value, unless the processing system grants a request for a variance;

wherein when the processing system grants a request for a first variance, the processing system allows the lamp to operate after the accumulated value is within the limit of the cutoff value.

2. The apparatus of claim 1

wherein when the processing system grants the request for the first variance, the processing system allows the lamp to operate for a first predetermined time.

3. The apparatus of claim 1 further comprising;

a stand alone control system;

and wherein the request for a variance is entered by an operator by using the stand alone control system.

4. The apparatus of claim 3 wherein

the stand alone control system displays a message indicating that the request for the first variance has been granted by the processing system.

5. The apparatus of claim 1 further comprising

a central controller;

and

wherein a variance can be requested by an operator of the central controller.

6. The apparatus of claim 5 wherein

the central controller displays a message indicating that the request for the first variance has been granted.

7. The apparatus of claim 2 further comprising

wherein when the processing system grants a request for a second variance the processing system allows the lamp to operate for a second predetermined period of time after the accumulated value is within the limit of the cutoff value.

8. A lighting system comprising

a plurality of image projection lighting devices;

and a central controller;

wherein each of the image projection lighting devices comprises;

a base;

a yoke;

a lamp housing;

the lamp housing comprising

a lamp,

and a first light valve;

a communications port;

a processing system; and

a memory, wherein an accumulated value representing an accumulated amount of operating time of the lamp is stored in the memory;

and wherein a lamp life warning regarding any of the lamps of any of the plurality of image projection lighting devices is sent to the central controller to the attention of an operator without operator inquiry.
