  • Patent number: 7329022
    Abstract: An improved small profile hanger system for ceiling suspended lighting fixtures comprises a plurality of hanger assemblies having a support stem and a downwardly arced crossbar. The support stem and crossbar have a relatively small elliptical profile have two sets of wire holes, each set of wire holes having an inner hole and an outer hole overlapping the inner hole, the inner and outer holes defining an intervening gap narrower than the dimension of either hole. The holes are sized to receive an insulated wire; the intervening gap preventing the wire from crossing over into the adjacent hole. The wire holes of the support stem are in communication with the wire holes of the crossbar providing a fully enclosed wiring passage from a ballast box assembly installed above a suspended ceiling to energize a lamp in a diffuser depending from a pair of the crossbars.

  • Patent number: 7325998
    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.
