Abstract

A bollard includes a bollard post having a lamp which includes a louver stack. The louver stack includes louvers spaced apart in the longitudinal direction of the bollard post. The bollard post is rectangular in cross section and the louver stack extends outwardly beyond the periphery of the bollard. There is a primary light source inwardly of the louver stack and a mechanism for providing light downwardly about the base end of the bollard post. One such mechanism includes an LED providing a light wash down the bollard post from beneath where that louver extends outwardly of the periphery of the bollard post. A second mechanism employs a top reflector above the primary light source to reflect light downwardly about the light source. Bottom reflector surfaces direct the light from the top reflector outwardly to louver reflectors located beneath the lowermost louver. Such reflectors can reflect light downwardly for light wash of the bollard post and an illumination about the base of the bollard post. The spacing between the lowermost louver and the periphery of the bollard post is exposed to the primary light source to create additional light downwardly to about the bollard post.
