    Abstract: A system can combine edgelit signage and edgelit illumination. The system can comprise two edgelit lightguide sections, one supporting signage and another supporting illumination. The lightguide section that supports signage can comprise a backlit face inscribed with text or graphics conveying an emergency message. The lightguide section that supports illumination can comprise a face patterned with features that release light, for example for emergency illumination. The two lightguide sections can be two areas of a single edgelit lightguide. The two lightguide sections can alternatively formed from two separate lightguides. In some examples, one or more illumination lightguide sections can be configured as a trim plate.

    Abstract: A lighting system includes a light source and a lightguide. The lightguide has a first edge disposed adjacent the light source to receive light from the light source and a second edge on a side opposite to the first edge, the second edge configured to emit at least a portion of the received light. The lightguide also has a first major surface and a second major surface that extend between the first edge and the second edge and that are on opposite sides of the lightguide. The first major surface and the second major surface internally reflect at least a portion of the received light. The lightguide consists of a first optical material and a second optical material, wherein the first optical material is disposed at the first edge adjacent to the light source and has a higher temperature rating than a second optical material.
