Abstract
Improvements introduced in luminaires for use with a light source comprising a refractor intended to receive light from said light source, characterized in that said refractor has a substantially oriented vertical front panel which is arranged in front of said light source and which includes prisms located in concentric paths generally above said light source and having their common center below the lower edge of said front panel, said prisms constituting means for receiving light at increasingly smaller lateral incidence angles along laterally disposed points to the vertical centerline of said front panel and to lower the light and redirect it laterally under lateral angles that vary laterally with respect to the vertical center line.
