Abstract

"ELEMENTOS RETROREFLETORES COM QUINAS CúBICAS TRIANGULARES-PIRAMIDAIS". Elementos de retroreflexão com quinas cúbicas triangulares-piramidais tendo uma refletividade significativamente excelente a um ângulo de incidência de 30<198> ou acima, de preferência de 40<198> ou acima. Elementos são caracterizados pelo fato de que se a altura a partir das faces inferiores (S~ x~S~ x'~) inclusive os lados inferiores (x, x, ... ) compartilhados por dois elementos de retroreflexão triangulares-piramidais opostos para os ápices (H~ 1~, H~ 2~) dos mesmos é h~ x~, a altura a partir das faces inferiores (S~ Y~-S~ Y'~) inclusive outros lados inferiores (y,y, ... )) dos elementos de retroreflexão triangulares-piramidais para os ápices (H~ 1~, H~ 2~) dos mesmos é h~ y~, e a altura a partir das faces inferiores (S~ x~-S~ x'~) inclusive demais outros lados inferiores (z,z, ... ) dos elementos de retroreflexão triangulares-piramidais para os ápices (H~ 1~, H~ 2~) dos mesmos é h~ x~, pelo menos duas de h~ x~, h~ y~, e h~ z~, são substancialmente diferentes e uma camada reflexiva especular é provida sobre a superfície do elemento de retroreflexão triangular-piramidal.
