Abstract

A lighting system for a motor vehicle including a plurality of replaceable, sealed lighting modules and means for mounting the modules in the vehicle in a pair of spaced-apart linear, horizontally disposed arrays. Each array possesses a maximum height of only about two inches and a width greater than the array height. All of the modules are similar and each includes a reflector with a lighting capsule mounted therein. The front of the module is enclosed by means of a optically clear cover exclusive of lens elements. A lens means is separately mounted in front of each array of lighting modules for controlling the light emitted therefrom to in turn provide both high and low beam patterns for the vehicle. Each of the arrays comprises four similar modules, resulting in a system containing a total of eight such components.

Claims

1. A lighting system for providing forward illumination for a motor vehicle, said system comprising:

first and second pluralities of replaceable, sealed lighting modules each including a reflector, a lighting capsule sealed within said reflector and mounted within said reflector in predetermined alignment therewith, and means for enclosing and sealing said module, said enclosing and sealing means including a clear cover member sealed to said reflector and not including lens elements thereon or as part thereof;

means for mounting each of said pluralities of said modules within said motor vehicle such that each of said pluralities of modules occupies a substantially linear and horizontally disposed array having a total vertical height of about two inches or less and a total width greater than said height;

a lens means associated with each of said arrays of modules and located a spaced distance therefrom for controlling the light emitted from each of said pluralities of said modules in said array to provide a predetermined forward pattern of light; and

means for mounting each of said lens means within said motor vehicle forward of said array of said modules.

2. The lighting system according to claim 1 wherein the number of said modules in each of said first and second pluralities of said modules is four, thereby providing a total of eight light-producing modules in said system.

3. The light system according to claim 2 wherein said four modules in each of said arrays are oriented in a juxtaposition relationship relative to said lens means.

4. The lighting system according to claim 2 wherein each of said four modules in each of said pluralities of modules is similar.

5. The lighting system according to claim 4 wherein said clear cover member sealed to said reflector is substantially planar.

6. The lighting system according to claim 4 wherein said lighting capsule in each of said modules is a tungsten halogen capsule having a quartz envelope and a pair of conductive lead-in wires.

7. The lighting system according to claim 6 wherein said tungsten halogen capsule is of the low wattage variety.

8. The lighting system according to claim 4 wherein said lens means associated with each of said array of four modules is a singular member common to said four modules.

9. The lighting system according to claim 8 wherein each of said singular, common lens members includes a lens surface thereon positioned so as to substantially face said modules.

10. The lighting system according to claim 8 wherein each of said singular, common lens members is contoured to substantially match the forward contour of said motor vehicle.

11. The lighting system according to claim 4 wherein activation of two of said four modules in each of said pluralities provides low beam illumination for said motor vehicle and activation of all of said modules provides high beam illumination for said motor vehicle.

12. The lighting system according to claim 1 wherein each of said modules is mounted within said motor vehicle in an easily releasable manner.
