Benefits of technology

[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.

Problems solved by technology

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.

Embodiment Construction

[0024] Referring to FIG. 1, an automobile 10 incorporating the present invention is shown therein. The automobile 10 includes an occupant compartment 12 located within the interior of the automobile 10 and a window assembly 14 mounted via a frame 16 to the automobile 10. As will be fully described in the following, the window assembly 14 provides illumination to the occupant compartment 12 as indicated by the arrows referenced by the numeral 18.

[0025] Although this description describes using the panel 14 as a sunroof or moonroof to provide illumination to the occupant compartment 12 of the automobile 10, the invention is equally applicable to other areas of the automobile 10. For example, the panel 14 may be appropriately located and dimensioned to provide the lighting requirements for a headlight, taillight, turn signal, brake light, instrument panel light, reverse light or any other light commonly found on automobiles.

Abstract

A window assembly having a first transparent area and a light emissive area. The panel includes a first transparent layer with an ultraviolet blocking layer and an abrasion layer. The light emissive area includes a light emissive layer that may be an organic light emitting display, an electroluminescent display, a polymer light emitting display or a light pipe configured to receive light from a light source.

Description

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 compartmen...
