Abstract:
A lighted sign housing, comprising:(a) a sign face having both light-transmissive portions and light-blocking portions; (b) a highly reflective film applied to at least a portion of the light-blocking portions of an interior surface of the sign face, wherein the highly reflective film is selected from the group consisting of a diffuse reflective film, a specular reflective film having a diffuse film laminated thereto and a specular reflective film having a diffused coating coated thereto; and (c) interior walls having a highly reflective film applied thereto, wherein the highly reflective film is selected from the group consisting of a diffuse reflective film, a specular reflective film having a diffuse film laminated thereto and a specular reflective film having a diffused coating coated thereto, wherein the highly reflective film applied to the interior walls and the highly reflective film applied to at least a portion of the light-blocking portions of the interior surface increase the average luminance of light passing through the light-transmissive portions and also provide enhanced luminance uniformity on the light-transmissive portions in comparison to a lighted sign housing having non-diffuse reflective films.
