Abstract
The present invention relates to a lighting unit of an automotive headlamp comprising: a series of two or more reflectors arranged side by side and coincident with each other; at least two light sources are arranged per reflector and disposed such that each light source provides light rays to the reflector targeted immediately adjacent to a focal point of the corresponding reflector and on opposing sides of the focal point; and the at least two light sources for each reflector are rotationally arranged at a set positional angle relative to the at least two light sources of the coincident reflector to produce a centered output beam.

A lighting unit of an automotive headlamp comprising:
- a series of two or more reflectors arranged side by side and coincident with each other;
- at least two light sources are arranged per reflector and disposed such that each light source provides light rays to the reflector targeted immediately adjacent to a focal point of the corresponding reflector and on opposing sides of the focal point;
- and
- wherein the at least two light sources for each reflector are rotationally arranged at a set positional angle relative to the at least two light sources of the coincident reflector.
A lighting unit of an automotive headlamp comprising:
- a series of four reflectors arranged side by side and coincident with each other;
- at least two light sources are arranged per reflector and disposed such that each light source provides light rays to the reflector targeted immediately adjacent to a focal point of the corresponding reflector and on opposing sides of the focal point;
- and
- wherein the at least two light sources for each reflector are rotationally arranged at a set positional angle relative to the at least two light sources of the coincident reflector.
A lighting unit of an automotive headlamp comprising:
- a series of four parabolic reflectors arranged side by side and coincident with each other;
- at least two light sources are arranged per parabolic reflector and disposed such that each light source provides light rays to the reflector targeted immediately adjacent to a focal point of the corresponding reflector and on opposing sides of the focal point;
- and
- wherein the at least two light sources for each reflector are rotationally arranged at a set positional angle relative to the at least two light sources of the coincident parabolic reflector, further wherein the set positional angle is between 60 and 120 degrees.
