Light emissive plastic glazingLight emissive plastic glazing description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20060209551, Light emissive plastic glazing. Brief Patent Description - Full Patent Description - Patent Application Claims
RELATED APPLICATION [0001] This application claims the benefit of U.S. provisional application entitled "LIGHT EMISSIVE PLASTIC GLAZING", application number, 60/663,237 filed on Mar. 18, 2005. BACKGROUND [0002] 1. Field of the Invention [0003] The present invention generally relates to vehicle occupant compartment lighting systems [0004] 2. Description of the known Technology [0005] The occupant compartment of a vehicle, more particularly an automobile, typically uses one or more lighting system to provide general lighting to the occupant compartment of the vehicle. This lighting enhances the visibility of areas within the occupant compartment that are not provided with their own lighting, such as areas occupied by occupants and their belongings, the center console and vehicle controls. The lighting system that provides general visibility to the occupant compartment is usually placed within the compartment such that the light it produces illuminates as much of the occupant compartment as possible, while taking up the least amount of space. One such lighting system, also called a "dome light", is located near the center of the roof of the occupant compartment. [0006] Automobiles can be equipped with transparent rectangular panels located near the center of the roof, commonly referred to as a "sunroof" or "moon roof". As stated earlier, the center location of the roof is the preferable position for the dome light. When a vehicle has a sunroof, the dome light must be moved to a less favorable location or eliminated, thus, reducing or eliminating effective general illumination of the occupant compartment. [0007] Therefore, it is desired to provide a system which will provide adequate illumination of the occupant compartment of vehicles equipped with sunroofs. BRIEF SUMMARY [0008] In overcoming the drawbacks and limitations of the know technologies, a light emissive window assembly is disclosed. The assembly includes a first transparent layer and light emissive layer coupled to the first transparent layer. The first transparent layer is made from a suitable material such as polycarbonate, polymethyl methacrylate, polyester blends or glass fibers or combinations thereof. The first transparent layer may further include an ultraviolet ("UV") blocking layer and/or an abrasion layer. [0009] The light emissive layer may be a multistack of functionalities and can be applied directly using conventional printing technologies such as inkjet, screen printing, dispensing and sputtering or any other suitable method. A more preferable manufacturer would be a multilayer film. The multilayer film may be an electroluminescent display, organic light emitting display, a polymer light emitting display, or may be a light pipe having an entry point for receiving light generated by a light source, whereby light received at the entry point will travel within the light pipe via total internal reflection. [0010] Additionally, a second transparent layer may be coupled to the emissive layer, thereby capsulating the emissive layer between the two transparent panels. The second transparent panel is constructed similarly to the first transparent panel and may have an abrasion layer and/or a UV blocking layer. The window assembly may be made by first forming a transparent panel having one side coated with an ultraviolet blocking layer and an abrasion layer. Next, a frame is formed around a potion of the perimeter of the plastic panel, thereby defining a cavity. A light source, such as the previously mentioned emissive layer, is placed within the cavity and bonded to the first transparent panel. A second transparent panel is thereafter attached to the frame and/or the first transparent panel, thereby encapsulating the light source. [0011] These and other aspects and advantages of the present invention will become apparent upon reading the following detailed description of the invention in combination with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0012] FIG. 1 is a perspective view of an automobile having a light emitting window assembly embodying the principles of the present invention; [0013] FIG. 2 is a top view of the window assembly embodying the principles of the present invention; [0014] FIG. 3 is a top view of another embodiment of the window assembly embodying the principles of the present invention; [0015] FIG. 4A is cross sectional view of a portion of the window assembly generally taken along lines 4-4 in FIG. 2; [0016] FIG. 4B is a cross sectional view similar to FIG. 4A of a window assembly using a polymer light emitting display; [0017] FIG. 4C is a cross sectional view similar to FIG. 4A of the window assembly of the window assembly using a polymer light emitting display as the emissive layer and a conductive ink; [0018] FIG. 4D is a cross sectional view of a window assembly using a PLED as the emissive layer; [0019] FIG. 4E is a cross sectional view similar to FIG. 4A of a window assembly made using a two shot process and embodying the principles of the present invention; [0020] FIG. 5 is a top view of another embodiment of the window assembly embodying the principles of present invention; Continue reading about Light emissive plastic glazing...
