Perimeter of sign warning system

Abstract

A perimeter-of-sign warning system is provided having a number of novel features. The provided system is defined by a warning flasher that encompasses the perimeter of a road sign. Its enclosure has provisions for mounting the sign, and a cross member provides additional support to the sign. Furthermore, the enclosure maintains perpendicularity between the face of the sign and the light output from the warning flasher, regardless of the orientation of the sign. The system also allows airflow through it, thus minimizing possible misalignment due to wind. Tamperproof hardware and plexiglas/Lexan panels provide protection against unauthorized access and vandalism. The warning flasher incorporates maintenance free solid-state light emitting diodes into its design. Its ‘light chaser’ flash pattern is designed to more effectively draw attention to the road sign to which it is associated.
