Abstract
One embodiment of a light-emitting diode (LED) optic comprises a light-transmitting element having a plurality of segments, each segment associated with an optical axis and comprising a linearly projected cross-section. For each segment of the light-transmitting element, the LED optic comprises at least one LED positioned such that a central light-emitting axis of the at least one LED is angled at about 0° relative to the optical axis associated with that segment. In one embodiment, the about 0° has a tolerance of ±10°. Each segment of the light-transmitting element comprises a light-entering surface, a light-exiting surface and a light-reflecting surface. In one embodiment, for each segment the at least one LED comprises a plurality of LEDs.

A light-emitting diode (LED) optic, comprising:
- a light-transmitting element having a plurality of segments, each segment associated with an optical axis and comprising a linearly projected cross-section;
- and
- for each segment, at least one LED positioned such that a central light-emitting axis of the at least one LED is angled at about 0° relative to the optical axis associated with that segment.
A method, comprising:
- arranging a plurality of segments of a light-transmitting element relative to each other, each segment associated with an optical axis and comprising a linearly projected cross-section;
- for each segment, positioning at least one LED such that a central light-emitting axis of the at least one LED is angled at about 0° relative to the optical axis associated with that segment;
- and
- transmitting light from the at least one LED.
A reflector optic, comprising:
- a plurality of light-transmitting means, each light-transmitting means being associated with an optical axis and comprising a means for transmitting light through a linearly projected cross-section;
- and
- for each light-transmitting means, at least one light source means positioned such that a central light-emitting axis of the at least one light source means is angled at about 0° relative to the optical axis associated with that light-transmitting means.
