Abstract
A reflective-ink lighting assembly includes a light transferring medium, a reflective-ink marking in the light transferring medium, and a light source adapted to insert light into the light transferring medium. In a lit state, light from the light source propagates through the light transferring medium by total-internal reflection. As propagated light reflects off the reflective-ink marking, some light exits through a façade of the light transferring medium to produce an illuminated marking. In an unlit state, the reflective-ink marking remains visible due to ambient light reflecting off the reflective-ink marking.
