Abstract
A window for a vehicle is provided herein. The window includes an outer panel separated from an inner panel. A light guide is disposed between the outer panel and the inner panel. A first light-blocking layer is disposed between the light guide and the outer panel. A second light-blocking layer is disposed between the light guide and the inner panel. A light source is optically coupled with the light guide and is configured to direct excitation light towards a photoluminescent structure disposed between the first and second light-blocking layers. The photoluminescent structure luminesces in response to receiving the excitation light.
Claims17
A window for a vehicle, comprising:
- an outer panel separated from an inner panel;
- a light guide disposed between the outer panel and the inner panel;
- a first light-blocking layer disposed between the light guide and the outer panel;
- a second light-blocking layer disposed between the light guide and the inner panel;
- and
- an ultraviolet light source optically coupled with the light guide and configured to direct excitation light towards a photoluminescent structure disposed between the first and second light-blocking layers, wherein the photoluminescent structure luminesces in response to receiving the excitation light, wherein the outer panel, the inner panel, the light guide and the first and second light-blocking layers form a window substrate of the vehicle.
A window for a vehicle, comprising:
- a light-blocking layer disposed inwardly of an outer panel;
- and
- a tapered light guide forming a window substrate of the vehicle with the light-blocking layer and the outer panel and configured to direct light from a light source towards a photoluminescent structure disposed inwardly of the light-blocking layer, wherein the photoluminescent structure defines visible indicia to approaching vehicles by luminescing upon receiving excitation light from the light source.
A light system for a vehicle, comprising:
- an outer panel having a light-blocking layer on an inner surface thereof;
- a light source optically coupled to a light guide, the outer panel and light guide forming a vehicle window substrate;
- and
- an indicia disposed inwardly of the light-blocking layer and defined by a photoluminescent structure that luminesces upon receiving light from the light source that is directed towards the indicia by optics on the light guide.
