Outdoor and/or enclosed structure LED luminaire

A luminaire, comprising:

• a main frame;
• a plurality of waveguides disposed in the main frame wherein each optical waveguide comprises first and second opposite waveguide ends, a coupling portion disposed at the first waveguide end, and a light emitting portion disposed between the first and second waveguide ends, wherein at least one of the waveguides is disposed at an angle relative to at least one other waveguide, wherein the coupling portions of the waveguides are disposed adjacent a first luminaire end and the second waveguide ends are disposed adjacent a second luminaire end opposite the first luminaire end, and wherein the light emitting portion of each optical waveguide comprises a plurality of light extraction features integral thereto;
• wherein each light emitting portion comprises an inner surface and an outer surface, wherein the inner surface is oriented toward an interior of the luminaire and the outer surface is oriented away from the luminaire;
• wherein the outer surface is a primary light emitting surface;
• at least one LED associated with each waveguide;
• wherein the at least one LED associated with each optical waveguide is adjacent the coupling portion of each optical waveguide of the plurality of waveguides;
• and
• wherein the at least one LED associated with each optical waveguide is enclosed by a combination of the main frame and a thermally conductive cover;
• and
• wherein the thermally conductive cover sinks heat developed by the at least one LED associated with each optical waveguide.

An optical waveguide assembly disposed in a luminaire, comprising:

• a body of optically transmissive material that exhibits a total internal reflection characteristic wherein the body is tapered in a first direction from a first end to a second end opposite the first end and comprises a constant cross sectional shape along a second direction transverse to the first direction;
• a light coupling portion disposed adjacent the first end of the body wherein the light coupling portion comprises refractive and reflective portions that direct light into the first end;
• light extracting features integrally disposed on the body of optically transmissive material and adapted to extract light out of the body of optically transmissive material, wherein the light extracting features comprise a channel and a ridge, such that at least one channel extends into the body and at least one ridge protrudes from the body;
• an intermediate surface disposed between the channel and the ridge, the intermediate surface substantially perpendicular to a center axis of the body of optically transmissive material, the light extracting features being configured such that the channel abuts a first end of the intermediate surface and the ridge abuts a second end of the intermediate surface;
• and
• a sensor for varying an illumination level of the luminaire in response to ambient light levels;
• wherein the light extracting features are disposed at varying pitches;
• wherein the body of optically transmissive material comprises an inner surface and an outer surface, wherein the inner surface is oriented toward an interior of the luminaire and the outer surface is oriented away from the luminaire;
• wherein the outer surface is a primary light emitting surface;
• and
• wherein the sensor is disposed within the interior of the luminaire.
