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° 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° from vertical. Unreflected light from the lamp which 'misses' both reflectors also provides a degree of “uplighting,” often found useful for aesthetic purposes.
