Abstract:
A lighting device for a motor vehicle is provided, for example a head lamp or a tail lamp. The lighting device includes an array of light sources, a lens assembly having a collimator lens, an inner lens, and an outer lens, and a housing to maintain the lens assembly in fixed relation relative to the array of light sources. The collimator lens includes a central geometry to manage high intensity light from directly above the LEDs and a lateral geometry to manage low intensity light that is offset from the LEDs, such that the light output from the LEDs exits the lens assembly with a homogeneous light distribution. The lighting device is suitable for vehicle applications, including internal lighting applications and external vehicle lighting applications. The lighting device can be manufactured by extrusion, making it well suited for low cost applications, such as interior ambient lighting.

Claim (Index 1):
An LED lighting device for a vehicle, the LED lighting device comprising:\n an outer lens; a plurality of LED light sources; and a collimator lens disposed between the outer lens and the plurality of LED light sources, the collimator lens being formed of a light transmissive material and including an upper lens section, a lower lens section, and a central lens section; wherein the upper lens section is integrally formed with the central lens section and is configured to emit incident light from the plurality of LED light sources by internally reflecting the incident light at an upper reflection surface; wherein the lower lens section is integrally formed with the central lens section and is configured to emit incident light from the plurality of LED light sources by internally reflecting the incident light at a lower reflection surface; wherein the central lens section includes a light emitting surface that defines a Fresnel lens for collimating the incident light from the plurality of LED light sources, the optical axis of the plurality of LED light sources extending horizontally through the central lens section, wherein the collimator lens is symmetrical about a horizontal plane of symmetry that intercepts the optical axis of the plurality of LED light sources, such that light emitted by the plurality of LED light sources emerges through the collimator lens as collimated light and is projected through the outer lens to generate a lighting function forward or rearward of the vehicle.
