Abstract

The present invention relates to an optical arrangement system for an automotive lighting device that includes a low-beam module adapted to generate a luminous intensity distribution with a kink or hot-spot feature where the low-beam module includes: a high luminous source to emit light along an optical axis; a reflector directing light emissions from the at least one high luminous source forward; a projection lens having a thin aspect-ratio value that is arranged in operative relationship with the reflector; a folder arranged in an optical path between the reflector and the projection lens that facilitates the luminous intensity distribution that generates with adaption of the kink or hot-spot feature; and where the reflector has a reflection surface whose center axis is not aligned with the optical axis.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An automotive lighting device with a laser light source that is configured to produce optical beam illumination comprising:
 a thin aspect-ratio lens of a low-beam module, the low-beam module adapted to generate a luminous intensity distribution with a hot-spot, wherein the laser light source is configured to emit light along an optical axis;   a reflector for reflecting light from a number of high luminous sources in addition to the laser light source;   said lens arranged in an operative relationship with the reflector; and   a folder arranged along an optical path between the reflector and said lens, where the folder includes a bump configured to generate the luminous intensity distribution with the hot-spot;   wherein the reflector has a reflection surface whose center axis is not coincidentally aligned with the optical axis.   
     
     
         2 . The automotive lighting device of  claim 1 , wherein the thin aspect-ratio lens has a width-to-height value of about 10:25 or height-to-width value of about 2.5:1. 
     
     
         3 . The automotive lighting device of  claim 1 , wherein the reflector includes a number of focal points relative to said lens. 
     
     
         4 . The automotive lighting device of  claim 1 , wherein a number of focal lengths relative to said lens includes values of a first focal point with about 4 mm and a focal length of a second focal point with about 30 mm. 
     
     
         5 . The automotive lighting device of  claim 1 , wherein one of the number of high luminous sources is arranged at a first focal point of an ellipse formed by the reflector. 
     
     
         6 . The automotive lighting device of  claim 1 , wherein the optical axis is radially offset from the center axis of the reflection surface. 
     
     
         7 . The automotive lighting device of  claim 3 , wherein a second of the number of focal points is at a distance of about 18 mm to 20 mm from said lens. 
     
     
         8 . The automotive lighting device of  claim 1 , wherein the luminous intensity distribution includes a maximum intensity of a hot spot region. 
     
     
         9 . The optical system arrangement system of  claim 1 , wherein one of the high luminous sources includes an alternative to the laser light source. 
     
     
         10 . The automotive lighting device of  claim 1 , wherein the bump has a spherical shape. 
     
     
         11 . The automotive lighting device of  claim 1 , wherein the bump has a triangular shape. 
     
     
         12 . The automotive lighting device of  claim 1 , wherein said automotive lighting device includes a high-beam module is configured to generate a high-beam distribution.
