摘要

summary "self-illuminating rear-lighting signal, self-illuminated front-lighting signal, two-sided self-illuminated front-lighting signal, two-sided self-illuminated front and rear-illumination signal" self-illuminated front and rear illumination signaling. signaling includes a deflection film having a structured surface for redirecting light and a diffuser providing diffusion. The signaling format from the observer's perspective provides the content, such as letters, to be transmitted to the observer. Two-sided signaling includes two rear-to-back signals, each including a deflection film having a structured surface for redirecting light, a diffuser providing diffusion, and a printed graphic. In double-sided signaling, deflection films receive light from an ambient light source and direct light through the structured surfaces toward the observers of the two graphs to passively illuminate the signaling. Two-sided signage can be shaped to provide content through format and graphics.
