Abstract
A luminaire globe member formed of light transmissive material and having a reflector section and a refractor section, light from a light source such as a high intensity discharge lamp initially impinging on at least major portions of the reflector section being reflected back into the interior of the globe member by prisms preferably disposed on exterior surfaces of said reflector section, refractive prisms preferably disposed on interior surfaces of the reflector section redirecting said reflected light through a focal point or loci of points directly above the light source, the light thus redirected from the reflector section being incident on surfaces of the refractor section at angles similar to angles of incidence of light rays directly emanating from the light source and directly incident on said refractor section surfaces, thereby to increase light efficiency by virtue of improved light control within the globe member.
