Abstract
A double ended high intensity lamp holder of the type used in television and motion picture lighting applications is provided with an improved lamp holder for securely and safely supporting a double ended lamp. The improved fixture includes a pair of lamp holder assemblies each including a generally U-shaped lamp holder member with a spring clip thereon for quick and easy snap-fit reception of the opposite ends of a double ended lamp. The two lamp holder members are resiliently suspended by a spring mounting arrangement from a corresponding pair of support brackets, whereby the double ended lamp is resiliently mounted in a manner substantially isolating and protecting the lamp against damage due to thermal stress, physical shock, vibration, etc.
Claims18
A double ended high intensity lamp holder for receiving and supporting a double ended lamp, comprising:
- a double ended lamp holder a frame, a pair of lamp holder members each including a spring clip for respectively snap-fit receiving and supporting opposite ends of the lamp, and means for resiliently mounting said lamp holder members on said frame whereby said lamp holder members movably accommodate thermal and mechanical stress during lamp use.
A double ended high intensity lamp holder for receiving and supporting a double ended lamp, comprising:
- a double ended lamp holder a frame, a pair of lamp holder members for respectively receiving and supporting opposite ends of the lamp, and means for resiliently mounting said lamp holder members on said frame whereby said lamp holder members movably accommodate thermal and mechanical stress during lamp use;
- and
- further including a pair of insulators mounted on said frame, and a pair of support brackets mounted respectively on said insulators, said means for resiliently mounting said lamp holder members comprising spring means for resiliently suspending said lamp holder members respectively from said support brackets.
A double ended high intensity lamp holder for receiving and supporting a double ended lamp, comprising:
- a double ended lamp holder a frame, a pair of lamp holder members for respectively receiving and supporting opposite ends of the lamp, and means for resiliently mounting said lamp holder members on said frame whereby said lamp holder members movably accommodate thermal and mechanical stress during lamp use;
- and
- further including a pair of heat shields for respectively shielding said lamp holder members from heat and radiation generated by the lamp during holder use.
A double ended high intensity lamp holder, comprising:
- a frame;
- and
- a pair of lampholder assemblies mounted on said frame, said lamp holder assemblies respectively including a pair of generally U-shaped lamp holder members for receiving and supporting opposite ends of a double ended bulb, and support means for resiliently supporting said lamp holder members to permit three dimensional displacement thereof relative to said frame, whereby said lamp holder assemblies movably accommodate thermal and mechanical stress during lamp use.
A double ended high intensity lamp holder, comprising:
- a frame adapted for mounting on a housing of a high intensity lamp holder;
- and
- a pair of lamp holder assemblies mounted on said frame for respectively receiving and supporting opposite ends of a double ended lamp having a light source disposed between said lamp holder assemblies;
- each of said lamp holder assemblies comprising an insulator mounted on said frame, a terminal block mounted on said insulator and including conductive means for connection to a power supply, a generally U-shaped support bracket mounted on said terminal block in a generally upwardly open orientation, a generally U-shaped lamp holder member, a plurality of support springs for mounting said lamp holder member in a resiliently suspended and upwardly open orientation within said support bracket, and a spring clip mounted on said lamp holder member for snap-fit retention of one end of a double ended lamp within said lamp holder member;
- said lamp holder assemblies being mounted on said frame with said lamp holder members generally aligned for respectively receiving and resiliently supporting the opposite ends of the double ended lamp.
