    摘要： An internally illuminated sign comprising an information display section having at least one flat or curved surface, exhibiting retroreflectivity to the light from the front surface of the sign and having a plane translucent to the light from the interior of the sign, an illuminator disposed on the back of the information display section, and a rectangular body for holding the information display section and the illuminator while closing. A retroreflective element being employed in the information display section is a prism type retroreflective element based on the principle of total internal reflection and a large number of prism type retroreflective elements are arranged while touching tightly each other to form a continuous retroreflective surface wherein at least the retroreflective part on the back of the large number of prism type retroreflective elements does not have a part coupling with other layers.

    摘要： A retroreflection device, wherein the first reflective side surface of a first triangular pyramid type retroreflective element is positioned on the same plane as the first side surface of a four−face type retroreflective element, the second reflective side surface of the first triangular pyramid type retroreflective element is positioned on the same plane as the second side surface of the four−face type retroreflective element, the third reflective side surface of the first triangular pyramid type retroreflective element is positioned parallel with one of two surfaces forming a V−shaped groove, the third reflective side surface of the second triangular pyramid type retroreflective element is positioned on the same plane or parallel with the other of two surfaces forming the V−shaped groove, and the third reflective side surface of the four−face type retroreflective element is positioned on the same plane as one of two surfaces forming the V−shaped groove.
