Perimeter of sign warning system
First Claim
1. A warning system comprising:
- An enclosure disposed peripherally about a regulatory, warning, or guide sign that is used for traffic control—
and whose shape shall be defined by the perimeter of said sign. For a sign with N sides, the enclosure shall possess N sides. A warning flasher system consisting of light bars or light panels incorporated into said enclosure. For a road sign with N sides, said warning flasher shall be comprised of a minimum of N light bars/panels. The length of each light bar/panel shall extend over a minimum of 30% of the length of the side of the road sign to which it is associated. Each light bar/panel shall be comprised of at least one independently controlled discrete light element. Each light bar/panel shall incorporate either solid-state light elements [i.e. Light Emitting Diodes] or incandescent light elements.

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.
