Lighting Devices Having Optical Waveguides for Controlled Light Distribution

A post top luminaire comprising:

• a housing including a cover, a base, and struts extending between the cover and base;
• and
• at least one waveguide positioned in the housing, the waveguide comprising:
• a top surface, bottom surface, and a light input surface defining coupling features for receiving light from a light emitter;
• a light transmission portion disposed between the light input surface and a light extraction portion, where the light propagates through the light transmission portion toward the light extraction portion;
• the light extraction portion comprising at least one light redirection feature and at least one light extraction feature that cooperate to generate a controlled light pattern exiting the waveguide body, wherein the at least one light redirection feature is disposed proximate the top surface of the waveguide body, and the at least one light extraction feature is disposed proximate the bottom surface of the waveguide body.

• a light input surface defining coupling features, wherein a light emitter is disposed adjacent the light input surface and emits light into the coupling features;
• a light transmission portion disposed between the light input surface and a light extraction portion, wherein light from the light emitter received at the light input surface propagates through the light transmission portion toward the light extraction portion;
• and
• the light extraction portion comprising at least one light redirection feature and at
• least one light extraction feature that cooperate to generate a controlled light pattern exiting the lighting device.
