Abstract
Abstract A lens member for use in a motor vehicle and adapted for being mounted in a recess within a front, contoured surface of the motor vehicle. The system especially designed for using the invention includes a plurality of separate lighting modules, each in turn including a light source and reflector means. The lens member comprises a hollow, enclosed, single piece lens element having a front, clear surface positioned to coincide with the vehicle's front, contoured surface so as to enhance aerodynamic performance of the lighting system (as well as the vehicle), a rear lensing portion positioned substantially at a predetermined angle (i.e., 0 to 30 degrees) relative to the front, planar surface of the modules located adjacent thereto, and side and bottom walls for enclosing the lens member to provide a sealed, dirt-free component.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A lens member for use in a lighting system designed for providing forward illumination for a motor vehicle wherein said lighting system includes a plurality of individual light sources located adjacent each other, said lens member comprising: a hollow, enclosed single piece element having a front, clear surface adapted for coinciding with the front, contoured surface of said motor vehicle, a rear lensing portion positioned at a predetermined angle relative to said individual light sources for having the light emitted by said sources pass therethrough, and a plurality of side walls for enclosing said element to provide a sealed, dirt-free member, said front clear surface and said side walls not including lensing elements thereon or as part thereof.
Claim 2
Dependent Claim
118 words
A lens member for use in a lighting system designed for providing forward illumination for a motor vehicle wherein said lighting system includes a plurality of individual light sources located adjacent each other, said lens member comprising: a hollow, enclosed single piece element having a front, clear surface adapted for coinciding with the front, contoured surface of said motor vehicle, a rear lensing portion positioned at a predetermined angle relative to said individual light sources for having the light emitted by said sources pass therethrough, and a plurality of side walls for enclosing said element to provide a sealed, dirt-free member, said front clear surface and said side walls not including lensing elements thereon or as part thereof.
Claim 3
Dependent Claim
39 words
The lens member according to claim 1 wherein said rear lensing portion includes a plurality of separate lens surfaces located internally of said single piece element and each adapted for aligning with a respective one of said light sources.
Claim 4
Dependent Claim
