Abstract

A control of gobos defend by records in the gobo. The gobos are formed by menued shapes.

Claims

1. A controller system for a lighting device, comprising:

a computing device having a user interface;

a gobo selection device which is operative to select one of a plurality of different gobos, on said user interface, each of said gobos including an image that is selected from said user interface,

said gobo selection device selecting gobos that are self animating gobos that are self animated to change at different times,

wherein said gobos include a gobo definition that loads and executes computer code in said computer, with variables to cause said computer to form an animation of the image, said animation defining the gobo, and causes the lighting device to display the animation, where said gobo definition includes an area to hold variables associated with the gobo, and where the gobo is changed at different times by the computer, as the animating by the computer modifying values of the variables, said animating causing the gobo to change its appearance in a random manner, wherein said output signals represent a light beam whose outer shape is defined by the gobo, wherein said gobo definition comprises an electronic file indicative of an image formed of a plurality of different layers, said plurality of layers including a first layer which includes a gobo image that shapes an outer perimeter of a light beam, and a second layer which defines a function of the gobo other than the gobo shaping.

2. A system as in claim 1, wherein said second layer defines a continuous rotation of the gobo image.

3. A system as in claim 1, wherein said second layer defines a blur of the gobo image.

4. A system as in claim 1, wherein said user interface allows selection of one of said gobos from an electronic gobo catalog, from which said gobos are electronically selected.

5. A system as in claim 4, wherein said gobo catalog is organized according to gobo geometries.

6. A system as in claim 4, wherein said electronic gobo catalog includes more commonly used gobos closest to an initial area of selection, and other gobos which are farther from the initial area of selection.

7. A system as in claim 6, wherein said gobos which are most commonly selected are determined by statistical techniques.

8. A system as in claim 6, wherein said initial area of selection is close to a root of the electronic gobo catalog.

9. A system as in claim 1, wherein said gobo defines a stencil for a light beam projection, and further comprising a controllable light that projects a light beam whose outer perimeter is defined by said gobo.

10. A controller system for a lighting device, comprising:

a computer;

a user interface that has electronics that control the computer to separately select a first portion of a first image representing a gobo and a second portion of a second image representing the gobo; and

a gobo production device, having a computer controllable device, and operating based on commands from said computer, which takes a combination of said first and second portions, and defines a combination gobo from said combination of said first and second portions without other portions of the gobo, wherein said combination gobo defines an outer perimeter of a projected light beam, and where said combination is based on a compare of each of a plurality of areas of said first portion and said second portion where said first and second portions overlap, and for each of said areas, displaying a brighter of the first and second portions where the first and second portions overlap, wherein said combination gobo is defined by a gobo definition that comprises an electronic file indicative of an image formed of a plurality of different layers, said plurality of layers including a first layer which includes a gobo image that shapes the outer perimeter of a light beam, and a second layer which defines a function of the gobo other than the gobo shaping.

11. A system as in claim 10, wherein said first image is a first color, and said second image is a second color, and where said first and second images overlap, a color is selected by finding which of the first and second images are brighter.

12. A system as in claim 10, wherein said combination is an exclusive or operation between said first portion and said second portion.

13. A system as in claim 10, wherein said user interface allows selection of one of said gobos from an electronic gobo catalog, from which said gobos are electronically selected.

14. A system as in claim 13, wherein said gobo catalog is organized according to gobo geometries.

15. A system as in claim 13, wherein said electronic gobo catalog includes more commonly used gobos closest to an initial area of selection, and other gobos which are farther from the initial area of selection.

16. A system as in claim 15, wherein said gobos which are most commonly selected are determined by statistical techniques.

17. A controller system for a lighting device, comprising:

a computer;

a user interface that controls separately selecting a first portion of a first image representing a gobo and a second portion of a second image representing the gobo; and

said computer including a gobo production device, which takes a combination of said first and second portions of said image, where said combination is a combination that is not a logical and between said first and second portions but said combination does not include other portions of the gobo other than said first and second portions, and defines a combination gobo from said combination of said first and second portions, wherein said combination gobo defines an outer perimeter of a projected light beam, where said first image includes a first color, and said second image includes a second color, and the projected light beam has the first and second colors respectively in areas where the images do not overlap, and has the first color in an area where the image is overlap if the first image is brighter than the second image, and has the second color in the area where the image is overlap if the second image is brighter than the first image, wherein sad combination gobo is defined by a gobo definition that comprises an electronic the indicative of an image formed of a plurality of different layers, said plurality of layers including a first layer which includes a gobo image that shapes the outer perimeter of a light beam, and a second layer which defines a function of the gobo other than the gobo shaping.

18. A system as in claim 17, wherein said gobo production device makes a logical “

OR”

combination of said first portion and said second portion of said first image.

19. A system as in claim 17, wherein said combination is a mathematical addition of said first portion and said second portion of said first image.

20. A system as in claim 17, wherein said user interface allows selection of one of said gobos from an electronic gobo catalog, from which said gobos are electronically selected.

21. A system as in claim 20, wherein said gobo catalog is organized according to gobo geometries.

22. A system as in claim 20, wherein said electronic gobo catalog includes more commonly used gobos closest to an initial area of selection, and other gobos which are farther from the initial area of selection.

23. A system as in claim 20, wherein said gobos which are most commonly selected are determined by statistical techniques.
