LIGHTING UNIT FOR A MOTOR VEHICLE
First Claim
1. A lighting unit (1) for a motor vehicle, the lighting unit comprising:
- a light module (2); and
a mirror module (3), wherein the mirror module (3) is adapted to reflect light emission produced by the light module (2) in an emission direction of the lighting unit (1),wherein;
the light module (2) comprises at least one light source (4) and a first heat sink (5),the mirror module (3) comprises a mirror unit (6) and a second heat sink (7),the lighting unit further comprises a cooling system (8) which comprises at least one inlet (9), at least one outlet (10), at least one line (11), at least one flow unit (12), a cooling medium, a first cooling sink and a second cooling sink, wherein the at least one inlet (9) and the at least one outlet (10) are connected by the at least one line (11) and the at least one flow unit (12) is inserted into the line (11) and configured to produce a flow of the cooling medium in the line (11) and thereby suck in the cooling medium through the at least one inlet (9) and expel the cooling medium through the at least one outlet (10), andthe first cooling sink is formed by the first heat sink (5) of the light module (2) and the second cooling sink is formed by the second heat sink (7) of the mirror module (3), wherein the first cooling sink is arranged downstream of the second cooling sink.

Abstract
The invention relates to a lighting unit (1) for a motor vehicle, which comprises a light module (2) and a mirror module (3), wherein the mirror module (3) is designed to reflect the light emission produced by the light module (3) in an emission direction of the lighting unit (1), characterized by: the light module (2), which comprises at least one light source (4) and a first heat sink (5), the mirror module (3), which comprises a mirror unit (6) and a second heat sink (7), a cooling system (8), which comprises at least one inlet (9), at least one outlet (10), at least one line (11), at least one flow unit (12), a cooling medium, a first cooling sink, and a second cooling sink, wherein the inlet (9) and the outlet (10) are connected by the line (11), and the flow unit (12) is inserted into the line (11) in order to produce a flow of the cooling medium in the line (11) and sucks in the cooling medium through the inlet (9) and discharges the cooling medium through the outlet (10), and the first cooling sink is formed by the first heat sink (5) of the light module (2) and the second cooling sink is formed by the second heat sink (7) of the mirror module (3), wherein the first cooling sink is arranged downstream of the second cooling sink.
