| Title: |
Lamp With a Lens Lenticule Pattern Based on the Golden Ratio |
| Abstract: |
A lens with lenticules arranged in a spiral pattern is described. In polar
coordinates the centers of successive lenticules are radially and
angularly spaced by spacing factors including Phi, the conjugate of the
Golden Ratio. The resulting spiraling lenticule pattern is free of
internal harmonics that lead to striation patterns in the lens refracted
light. At the same time the size of the beam spot can be set by reflector
size and lenticule profile.
