Abstract
A light fixture includes a parabolic reflector, a light source positioned at the focal point of the parabolic reflector and a lens assembly. The lens assembly includes a front lens for transmitting the primary beam reflected from the parabolic reflector. The lens assembly also includes a first lens section including one, two or more lateral focussing elements positioned between the front lens and the edge of the parabolic reflector to intercept omnidirectionally radiated light rays from the light source and to redirect the intercepted light rays into collimated lateral beams to illuminate selected areas at the side of the light fixture.
