Abstract

A lighting module and a headlamp for vehicle lighting are provided. The lighting module includes a dynamic bending light module; and a lens that is situated in operative relationship with the dynamic bending light module; wherein the lens has a thin aspect.

First claim

The invention claimed is:

1. A lighting module for a low-beam headlamp comprising:
a dynamic bending light module configured to generate an elbow or kink from a cut-off profile of a light beam pattern, the dynamic bending light module including a number of organic light emitting diodes (OLEDs) arranged on a LED board and a collector lens;
an alignment module separate from the dynamic bending light module, the alignment module configured to provide light to the light beam pattern generated by the dynamic bending light module;
a lens that is situated in operative relationship with the dynamic bending light module and the alignment module;
wherein the lens has a thin aspect ratio that is generally narrow along a length of the lens and is situated with the low-beam headlamp that is tall and narrow;
the dynamic bending light module being configured to rotate independently of the alignment module; and
a drive device configured to perform a rotation of the dynamic bending light module wherein rotation is controlled by a controller device coupled to a steering wheel sensor.

2. The lighting module of claim 1 , wherein the drive device is configured to rotate the dynamic bending light module with an angle of rotation of + or −15 degrees.

3. The lighting module of claim 2 , wherein the LED board and the collector lens rotates with the dynamic bending light module.

4. The lighting module of claim 1 , wherein the dynamic bending light module expands the number of organic light emitting diodes to also includes a number of light emitting diodes, polymer light emitting diodes (PLEDs), laser light sources or some combination therefrom.

5. A low-beam headlamp of a vehicle, said headlamp comprising:
a lighting module including
a dynamic bending light module configured to generate an elbow or kink from a cut-off profile of a light beam pattern, the dynamic bending light module including a number of organic light emitting diodes (OLEDs) arranged on a LED board and a collector lens;
an alignment module that is spaced separate from the dynamic bending light module, the alignment module is configured to provide light to the light beam pattern generated by the dynamic bending light module; and
a lens that is situated in operative relationship with the dynamic bending light module and the alignment module;
wherein the lens has a thin aspect ratio that is generally narrow along a length of the lens and is situated with said headlamp that is tall and narrow;
the dynamic bending light module being configured to rotate independently of the alignment module;
where the lighting module further includes a drive device that is configured to rotate the dynamic bending light module and wherein rotation is controlled by a controller device coupled to a steering wheel sensor.

6. The headlamp of claim 5 , wherein the drive device is configured to rotate the dynamic bending light module with an angle of rotation of + or −15 degrees.

7. The low-beam headlamp of claim 5 , wherein the dynamic bending light module expands the number of organic light emitting diodes to also include a number of light emitting diodes, polymer light emitting diodes (PLEDs), laser light sources or some combination therefrom.

8. A dynamic bending light module of a vehicle's headlamp, the dynamic bending light module comprising:
a collector lens;
a number of organic light emitting diodes (OLEDs), wherein the collector lens and the number of OLEDs are configured to rotate independently of an alignment module of a low-beam headlamp, where rotation is controlled by a controller device coupled to a steering wheel sensor,
where the alignment module provides light to a light beam pattern generated by the dynamic bending light module and is situated in an operative relationship with a lens having a thin aspect ratio that is generally narrow along a length of the lens and is situated with the low-beam headlamp; and

wherein the dynamic bending light module is configured to generate an elbow or kink from a cut-off profile of the light beam pattern.

9. The module of claim 8 , further comprising: a drive device coupled to the collector lens and the number of OLEDs.

10. The lighting module of claim 9 , wherein the drive device is configured to rotate the dynamic bending light module with an angle of rotation of + or −15 degrees.

11. The dynamic bending light module of claim 8 , wherein the dynamic bending light module substitutes the number of organic light emitting diodes to include a number of light emitting diodes, polymer light emitting diodes (PLEDs), laser light sources or some combination thereof.
