Abstract
The present invention includes an adjustable lighting fixture having a housing and light holders which are able to extend, pivot, spin, and slide with respect to the housing, a mounting arm, or each other. The lighting fixture may thus provide enhanced lighting during events, such as live performances, teleconferencing, filming, or videotaping. Each adjustable lighting fixture generally includes a light holder positioned on a mounting arm pivotally or otherwise movably connected to the housing. The lighting fixture uses fluorescent light sources. When enhanced lighting is not required, the light holders may be restored in the housing in an aesthetic manner.
Claims58
An adjustable fluorescent lighting fixture comprising:
- a housing, said housing forming an interior cavity;
- a light holder positioned in said interior cavity of said housing, said light holder configured to move from a storage position to an enhanced lighting position with respect to said housing;
- a fluorescent light source connected to said light holder;
- and
- a ballast connected to said fluorescent light source, said ballast selected from the group consisting of a digitally adjustable ballast to dim and brighten the light source and a ballast adjustable by analog control to dim and brighten the light source.
2 more elements
An adjustable fluorescent lighting fixture comprising:
- a housing, said housing forming an interior cavity;
- a light holder positioned in said interior cavity of said housing;
- a mounting arm configured to move said light holder from a storage position to an enhanced lighting position with respect to said housing;
- and
- a fluorescent light source connected to said light holder,
- wherein said adjustable lighting fixture is configured to provide fluorescent downlighting when said light holder is in a storage position and enhanced fluorescent lighting when said light holder is moved via said mounting arm into said enhanced lighting position, and said light holder is electro-mechanically movable from said storage position to said enhanced lighting position.
3 more elements
A fluorescent lighting system comprising:
- an adjustable fluorescent lighting fixture having a light holder and a fluorescent light source connected to said light holder in a housing;
- means for moving said light holder from a storage position to an enhanced lighting position, said means for moving said light holder comprising a pin and a pin mounting bracket, said pin mounting bracket fixed with respect to said light holder housing and said light holder and said pin rotatable with respect to said pin mounting bracket;
- a ballast connected to said light holder, said ballast selected from the group consisting of a digitally adjustable ballast to dim and brighten the light source and an adjustable analog ballast to dim and brighten the light source;
- and
- a controller connected to said ballast and said means for moving said light holder, wherein said ballast receives a signal from the controller, said signal selected from the group consisting of an analog signal and a digital signal.
2 more elements
An adjustable fluorescent lighting fixture comprising:
- a housing, said housing comprising a hollow box having a first wall, a second wall, a third wall opposite said first wall, and a fourth wall opposite said second wall, thereby forming an interior cavity;
- a light holder positioned in said interior cavity of said housing, said light holder configured to move from a storage position to an enhanced lighting position with respect to said housing, said light holder having a longitudinal axis, wherein the longitudinal axis of said light holder passes through an intersection of the first and second walls and an intersection of the third and fourth walls of the housing, and the light holder is rotatably movable 1 to 180 degrees about said longitudinal axis;
- and
- a fluorescent light source connected to said light holder.
1 more element
An adjustable fluorescent lighting fixture comprising:
- a housing, said housing forming an interior cavity;
- a light holder positioned in said interior cavity of said housing;
- a mounting arm configured to move said light holder from a storage position to an enhanced lighting position with respect to said housing, and
- a fluorescent light source connected to said light holder,
- wherein said adjustable lighting fixture is configured to provide fluorescent downlighting when said light holder is in a storage position and enhanced fluorescent lighting when said light holder is moved via said mounting arm into said enhanced lighting position, and
- further wherein the fluorescent light source is connected to a ballast, said ballast selected from the group consisting of a digitally adjustable ballast and a ballast adjustable by analog control, to brighten and dim the fluorescent light source.
3 more elements
A fluorescent lighting system comprising:
- an adjustable fluorescent lighting fixture having a light holder and a fluorescent light source connected to said light holder in a housing:
- means for moving said light holder from a storage position to an enhanced lighting position;
- a ballast connected to said light holder;
- and
- a controller connected to at least one of said ballast and said means for moving said light holder,
- wherein the controller is connected to the ballast, and
- further wherein the ballast receives a signal selected from the group consisting of an analog electronic signal from the controller and a digital signal front the controller.
