发明名称 Reduced package depth low profile lamp with conic section cylinders
摘要 A reduced package depth low profile lighting system has a light source emitting light at a solid lens for shaping the light to conform to governmental lighting standards. The solid lens has a first surface comprised of a plurality of conic section cylinders. Each of the cylinders has a length first focal line, a second focal line and a cylinder line. The first focal line is tangent to a package curve preferably defined by a circle preferably in the horizontal plane of the vehicle. The circle has a center and a predetermined radius length. The center is coincidence with the light source. Each of conic cylinders substantially collimates light in the vertical plane while spreading light in the horizontal plane within a predetermined angle from the optical axis.
