AbstractA lens assembly is disclosed for use with various light emitting sources. The lens assembly includes a central section and an outer section. The central section is radially centered on an optical axis. The outer section radially surrounds the central section and is radially centered on the optical axis. The outer section includes an outer wall that has a generally rotated parabolic shape, an inner wall that abuts the central section, and a slanted front surface extending between the inner wall and the outer wall. The front surface is the area of the lens assembly axially farthest away from the light emitting source.
