Abstract
The improved bollard luminaire has an upwardly directed, elliptical main reflector and a lamp "nested" within such reflector and positioned at or near its lower focal point. An upper cone-shaped reflector receives light from the main reflector and directs it laterally through a transparent lens element. Such element provides a 360.degree. lateral light opening unobstructed by wiring, support posts or the like. Light reflected through such opening is relatively sharply focused along an axis about 70.degree. from vertical. Unreflected light from the lamp which "misses" both reflectors also provides a degree of "uplighting," often found useful for aesthetic purposes.

- a lamp positioned below such rim;
- an upper reflector receiving light from the main reflector and reflecting such light at an angle less than 90.degree. from vertical;
- whereby such reflected light is directed laterally through such opening for ground illumination.
