Abstract
A lens for a light-emitting diode (LED) provides an even light pattern over a desired throw of light. An indentation on the top of the lens and a lens collector on the bottom are configured for a desired spread angle of light refracted an LED positioned on a circuit board below the light collector of the lens. One or more lenses may be formed in a lens unit for assembly with a circuit boards and molding into an LED module. The module may be used in sign cabinet and other lighting applications where LEDs are used as light sources.
