  • Cast photoluminescent devices and photoluminescent inserts for substrates
    Patent number: 8192829
    Abstract: A non-powered path marking system comprises a substrate defining a cavity. A photoluminescent insert comprises a first resinous layer that is cast with photoluminescent particles suspended therein. Adhesive attaches the photoluminescent insert inside of the cavity. A marking device comprises a photoluminescent insert comprising N cast resinous layers, wherein N is an integer greater than or equal to one. A first one of the N cast resinous layers includes photoluminescent particles suspended therein. A fastener includes a first portion cast in the photoluminescent insert and a second portion extending outside of the photoluminescent insert.

  • Substrate such as paving brick with non-powered photoluminescent portion
    Patent number: 7993722
    Abstract: A non-powered photoluminescent paving brick includes a substrate defining one of a cavity and a channel that extends from one end to an opposite end of the substrate. A photoluminescent portion includes a light transmissive resin including a suspension of photoluminescent particles. The photoluminescent portion is arranged in the one of the cavity and the channel and wherein the light transmissive resin has an exposed outer surface that directly receives light.
