Ambient lighting for vehicle interior floor console

## Abstract

A floor console to provide ambient lighting in the interior of a vehicle is disclosed. The floor console includes lighting elements strategically positioned to illuminate the footwells of the vehicle, the cupholders, and the storage bin. The same lighting element may be used to illuminate one or more of the cupholders and the storage bin. The preferred lighting element is an LED while other lighting elements may be used. The floor console is also provided with wiring and an ECU and may be readily connected to the vehicle's power system.

## Background
TECHNICAL FIELD
The present invention relates generally to interior lighting systems for motor vehicles. More particularly, the present invention relates to an interior lighting system integrated with the floor console of a motor vehicle which provides ambient lighting.
BACKGROUND OF THE INVENTION
Modern vehicle interiors are provided with lights for the safety and comfort of the driver and passengers. In its simplest configuration, vehicle interior lighting is provided in the form of a dome lamp mounted in the approximate center of the vehicle ceiling. While typically providing functional and adequate lighting, the dome lamp arrangement creates shadows and leaves many areas of the interior without direct illumination.
In an effort to improve vehicle interior lighting, additional lights have been included in a variety of places. For example, lights have been fitted to the underside of instrument panels as well as under vehicle seats to illuminate the floor and footwells. Lights have also been fitted to utilitarian areas such as cup holders. Unlike the dome light arrangement, these lights provide indirect or ambient lighting to the vehicle interior. Such ambient lighting may be configured to provide light to almost all areas left dark by conventional dome lights, thus adding to comfort and safety.
While providing an improvement in vehicle lighting, known ambient lighting typically adds complexity in the forms of lighting elements (tubes, bulbs, or light emitting diodes [LEDs]), switches, controllers, and wiring. According to known arrangements, a relatively large number of discrete components are required to provide the desired level of lighting. In one known vehicle, in addition to a relatively complex web of wiring, thirteen discrete components are needed—four light tubes, two switches, one ECU (electronic control unit) and six LED assemblies.
Regardless of the design, according to current technology several individual ambient lighting components are disposed at various strategic locations in the interior, thereby complicating assembly of the vehicle as a whole. Specifically, wiring for under-seat lights must be installed before the vehicle carpet is installed. Light elements for both under-instrument panel and under-seat lights must be installed before the instrument panel or the seat is installed in the vehicle. This installation arrangement is cumbersome for assembly processes and adds significant expenses in both the planning and execution of vehicle assembly. In an effort to reduce the scheduling and planning burdens, some of these components, such as the wiring harness, are installed in the vehicle whether or not the customer orders optional ambient lighting, thus adding to vehicle cost.
To a certain extent the application of ambient lighting systems has been simplified by assemblies offered in the aftermarket where ambient lighting packages for vehicle interiors are available. These systems, however, are difficult to install and require that the necessary wiring be spliced at inconvenient areas, such as at the cigarette lighter for footwell lighting and at the PRNDL (park, reverse, neutral, drive, low) mechanism for cupholder lighting.
Accordingly, as in so many areas of vehicle design, an improved method of providing vehicle lighting is desired.
SUMMARY OF THE INVENTION
The present invention represents an advancement in the art of interior vehicle lighting by providing an ambient lighting system for a vehicle which comprises a floor console having integral lighting elements, wiring harness, connectors and an ECU. According to the present invention, the floor console may be configured and employed so as to provide all of the lighting needed to effect a complete, comfortable and inviting ambient lighting environment within a vehicle, rendering unnecessary the need for other interior lighting. The floor console of the present invention may be built by an outside supplier and installed by the vehicle builder during final assembly without the vehicle builder having to plan for or install in advance under-carpet wiring, lighting elements, and control elements (such as an ECU) at other locations in the vehicle interior as is required by the prior art.
The floor console of the present invention includes ambient lighting elements strategically positioned to illuminate the front footwells of the vehicle as well as the rear footwells. In the event that the floor console is provided with cupholders separate ambient lighting elements may be provided for the cupholders as well. In addition, the floor console may include one or more storage bins which may also be lighted by the console lights. In one embodiment a cupholder is removably mounted in a storage bin of the floor console, allowing the vehicle operator and passenger access to the bin once the cupholder is removed. According to this arrangement a single, dual-function lighting element may be used to illuminate both the removable cupholder and the storage bin.
The floor console may be constructed as a two-piece unit which includes a base and an upper portion that is attachable to the base. The upper portion is preferably attached to the base after the base is installed in the vehicle interior. Alternatively, the floor console may be constructed as a single, integrated component. In either embodiment, the related wiring harness and connectors are installed inside the floor console as are the necessary control elements, such as an ECU. For the sake of assembly efficiency, a single conduit is preferred to connect the console to the vehicle's power system. Overall the number of required components is reduced compared with conventional ambient lighting arrangements.
The several lighting elements are preferably LEDs, although other lighting elements such as tube and bulb elements may be used in the alternative or may be used in combination with LEDs.
The console of the present invention provides the vehicle manufacturer with a simplified and cost-reducing way of adding ambient lighting to the interior of the vehicle. By providing a console having integral ambient lighting elements, the need to install wiring, conduits and lighting elements in other locations in the vehicle interior at multiple stages of assembly is eliminated. This reduces inconvenience and costs at both the planning and assembly stages. The component cost is further reduced by using fewer lighting elements to effect good illumination such as having cupholders and the storage bin both illuminated by the dual-function lighting element. In addition, the console of the present invention may be provided as an attractive after-market feature which may used to replace the factory-installed standard console.
Other advantages and features of the invention will become apparent when viewed in light of the detailed description of the preferred embodiment when taken in conjunction with the attached drawings and the appended claims.
