Abstract
An apparatus for distributing light from a light source includes a support and an optic supported by the support. The optic includes a truncated axially symmetric body.
Claims15
An apparatus for distributing light from a light source, the apparatus comprising:
- a support;
- and
- an optic supported by the support, the optic comprising a truncated axially symmetric body having a section removed from the body defining a removed section from a top to a bottom of the body.
A method for illuminating a target plane, the method comprising:
- placing an optic over a light source, wherein the optic comprises a truncated generally axially symmetrical body defined around a first axis, the body having a removed section;
- passing light from the light source through the optic onto a target plane on an opposite side of the optic from the light source;
- and
- directing light from the light source directly onto the target plane through the removed section bypassing the optic.
1 more element
An assembly for directing light comprising:
- a support;
- and
- an optical body mounted on the support, the optical body comprising a truncated generally axially symmetric peripheral wall and at least two other peripheral walls each abutting the truncated generally axially symmetric peripheral wall, wherein the body is truncated with respect to its axial symmetry to define a removed section to allow first incident light from an associated light source to be directed in front of the associated light source without passing through the body.
