Abstract
A LED signal includes a housing and a cover. At least one LED is arranged on a PCB and mounted within the housing. A collimator that collimates light energy emitted by the at least one LED is positioned adjacent to the at least one LED. A diffuser is positioned adjacent to the collimator and spreads collimated light transmitted through the collimator. The PCB, the collimator, and the diffuser are disposed between the cover and the housing, and the cover provides a protective barrier between environmental conditions and the collimator and diffuser.
