| Title: |
Variable Spot Size Lenses and Lighting Systems |
| Abstract: |
Improved lighting devices and methods are provided. In many embodiments,
the devices and methods provide the capability to change a spot of light
projected onto a target surface. In other embodiments, the devices and
methods are fixed-focus. In one embodiment a lens can have a lens body
with anterior and posterior surfaces. The anterior surface can be adapted
to receive light from a light source. The posterior surface can have a
central portion and a peripheral portion. Some of the light from the
light source can pass through the lens body and exit the central portion
of the posterior surface via refraction. Some of the light from the light
source can pass through the lens body and exit the peripheral portion of
the posterior surface via both refraction and reflection at various
surfaces of the lens.
