A method and apparatus for light transmission adapted for use in a reflective belt, safety vest, or similiar devices requiring visibility of a bright and/or reflective material where a light source of one or more lighting elements is positioned to transmit light along a self-supporting elongated light transmitting member of a hot-melt adhesive thermoplastic material and a flashing circuit for the light source which includes a battery pack or any other power source convertable to D.C. voltage. The hot-melt adhesive is of a high clarity, highly flexible material which transmits light in a highly visible manner within an elongated casement of material formed of a light-colored backing material and a front strip of a translucent material adapted to transmit the light driven along the member by the light-emitting source. Any light-emitting source, either visible or invisible would be suitable for the transmitting device. Similarly, the casement of material, elongated members, light-emitting sources and circuit and D.C. power source could be mounted on either the front and/or rear panel of a safety vest where the vest is desirable for high visibilty in darkness or dimly lit situations.
A portable reflective belt to be worn by a user of the portable reflective belt comprising a belt formed of a flexible material and having a length to allow it to encircle the waist of the user, a battery pack and circuit mounted on said belt, said belt providing an elongated envelope containing a plurality of light sources spaced along the length of the belt, and at least one elongated light-transmitting member having said light sources positioned therealong and acting to transmit the light along the length of said member, said member being formed of a flexible, substantially transparent hot-melt adhesive thermoplastic material providing exceptional light transmission characteristics.
A safety vest to be worn by a person to be seen on or nearby roadways and highways, comprising a vest garment of colorful and reflective material having a front panel and a back panel joined over the shoulders, and means to connect said front and back panels by side attachment means, and a light transmitting strip on either the front or back panel or both, each said light-transmitting strip having an elongated encompassing casement of material and containing one or more light-transmitting members of a flexible homogenous hot-melt adhesive thermoplastic material and one or more light sources at the ends of said members, and a battery pack and circuit for flashing the light sources.
An apparatus comprising at least one light source and at least one member of a flexible and substantially transparent hot-melt adhesive thermoplastic material characterized by its ability to transmit and radiate light, said light source being positioned adjacent the member.
An apparatus comprising at least one light source and at least one member of an elongated flexible homogenous hot-melt adhesive thermoplastic material having a longitudinal axis, the light source being positioned along the longitudinal axis of the member.
A safety belt comprising an elongated and substantially transparent hot-melt adhesive thermoplastic material having a round top and a lower surface having a concave recess formed therein;
