Abstract

Several potential OLED lighting applications are discussed for automotive interior task, courtesy, ambient, orientation, safety, utility and decorative lighting. These applications include map/reading lamps, dome/courtesy lamps, ambient/orientation/ conversation/utility lamps, trunk lamps, cargo lamps, visor vanity lamps, glove box lamps, ash receiver lamps, cup holder lamps, storage bin lamps, footwell lamps, door lamps, and various other lamps and backlit components. These lamps may be formed in any shape/design and may allow an end user to select the color of light produced by these lamps. These lamps can include various other optical components and circuitry components. OLEDs may be configured to be transparent, flexible, and/or stacked. The OLEDs can be attached to a vehicle or vehicle component in any number of different manners as discussed below.

Description of Innovation

Background

    Organic Light Emitting Diodes (OLEDs) have been introduced. These OLEDs have several unique properties that allow various designs to be implemented which may be more difficult to implement using traditional light sources. OLEDs will offer new options for styling, placement, and integration of lamps, backlit components, and displays. They consume substantially less power than incandescent lamps and they generate less heat. Further, these OLEDs may serve as a replacement for traditional light sources. It is anticipated that OLEDs will have 'life-of-vehicle' reliability. It is hoped that OLED lamps will be able to be produced at lower costs than LED lamps. However, OLED lamps lamps have other benefits that would justify higher costs.

There are various types of specialized OLEDs that have currently been developed. These types include Transparent OLEDs (TOLED), Flexible OLEDs (FOLED), and Stacked OLEDs (SOLED). A particular OLED may incorporate one or more of these properties (e.g. an OLED may be both flexible and transparent. TOLEDs, FOLEDs, SOLEDs, and any other variation of

OLEDs can all potentially be utilized for the applications listed below. References below to OLEDs is meant to include all of the potential variations. Also, reference to OLED is also a reference to polymer/polymeric light emitting diodes (PLEDs) which may also be formed in one or more of the combinations listed above (transparent, flexible, stacked, etc.).

Applications

* Dome/courtesy lamps

A dome/ courtesy lamp incorporating an OLED may be designed to be a surface emitter instead of point/line emitter (such as from LED, bulb). Additionally, lamps do not need to be simple, geometric shapes. For instance, the lamp could be in a shape of a logo or a decorative shape. Additionally, the OLED may be designed to be color selectable (i.e. a supplier and/or end user could select the color to emit from the OLED light source based on their own preferences). Some non-limiting examples of locations which may incor...
