Abstract

Anordning ved belysning av trafikkskilt, reklameskilt, opplysningsskilt og lignende hvor det anvendes belyste plater, samt ved generell belysning. Skiltet består av en transparent lyskildeplate (2) med i og for seg kjent innkoblet lys via optiske kabler på minst en av sine sideflater. Lyskildeplatens (2) bakside er forsynt med riller (4) og vendt mot en reflekterende plate (3). Vendt mot lyskildeplatens (2) overside er anordnet en diffus plate (1) med derpå anbrakte fremvisningssymboler (7).Device for illumination of traffic signs, advertising signs, information signs and the like where illuminated plates are used, as well as for general lighting. The sign consists of a transparent light source plate (2) with known light, which is known per se via optical cables on at least one of its side surfaces. The back of the light source plate (2) is provided with grooves (4) and faces a reflective plate (3). Faced with the upper side of the light source plate (2) is a diffuse plate (1) with display symbols (7) arranged thereon.
