| Title: |
Universal Lens Mounting for Selective Spotlight Beam Spread |
| Abstract: |
A lens casting or housing provides a series of grooves for selective
mounting of various lenses to achieve various beam spreads. By spacing
lenses in the housing, it is possible to reduce the diameter and thickness
of the lens nearer the light source with consequent improvement in thermal
characteristics as well as efficiency in light transmission.
