  • Internally illuminated retroreflective sign
    Patent number: 4952023
    Abstract: An internally illuminated sign employs retroreflective sheeting with optically transmissive bonds between cover layer and base layer, thereby making the sign suitable for applications where visibility of the sign is required if the internal illumination source fails. A light conduit may be employed to allow the source of internal illumination to be remote from the interior of the sign enclosure. Total internal reflection type sheeting also may be employed to diffuse the internal illumination.
