    摘要： A light-emitting diode (LED) reflector optic (24) comprises a reflector having a plurality of reflecting surfaces (32). The reflector (28) is associated with at least one optical axis (36). In one embodiment, each reflecting surface comprises a linearly projected cross-section (40). In one embodiment, the LED reflector optic (24) also comprises at least one LED (52) positioned such that a central light-emitting axis of the at least one LED (52) is angled relative to the at least one optical axis at about 90°. In one embodiment, the about 90° has a tolerance of ±30°. In one embodiment, each reflecting surface (32) comprises at least one of: a conic or a substantially conic shape. In one embodiment, the at least one LED comprises a plurality of LEDs, the at least one optical axis comprises a plurality of optical axes, and each of the plurality of LEDs is angled relative to a respective one of the plurality of optical axes at about 90°. In one embodiment, a plurality of linear extrusion axes are angled relative to each other.
