Abstract
A luminaire of otherwise conventional design for street or roadway outdoor lighting which employs as its structural housing, members fabricated of suitable plastic material. The slipfitter structure and the base member on which the weighty electrical components are mounted is made of material having superior tensile strength such as cast aluminum. The aluminum base member is fitted closely and secured to the plastic housing. Thus, the portion of the luminaire most subject to stresses is aluminum while for the larger exterior areas suitable molded plastic may be used. The contours of the aluminum base member form an arched structure for supporting the comparative light weight but physically bulky upper plastic housing. By this construction, the plastic housings are placed in compression but all tensile forces are applied to the base member. In this way the plastic housing merely forms a protective shroud for the luminaire.
