| Title: |
Lens Carrier |
| Abstract: |
A lens carrier (10) is disclosed for use in a stage lamp. The lens carrier
(10) supports a lens (26) in alignment with the lamp axis (12) while
permitting limited movement of the lens along the lamp axis to focus the
lamp toward the light. First and second members, (14, 22) define facing
cylindrical surfaces (20, 24). A bearing assembly (28) having resilient
deformable ball bearings (34) is positioned between the cylindrical
surfaces to maintain alignment of the lens on the lamp axis and permit the
second member and lens to move along the lamp axis relative to the first
member while maintaining the alignment.
