Abstract

It is provided a lamp assembly (10) for an automotive headlamp, comprising an LED (12) for emitting light rays, a housing (16), to which the LED (12) is detachably connectable, wherein the housing (16) comprises an entrance window (20) assigned to the LED (12), and a guiding element (22) for guiding the light rays passing through the entrance window (20), wherein the guiding element (22) is connected to the housing (16). Since the LED (12) is detachable connected to the housing (16) a defect LED (12) can by exchanged by only exchanging the LED (12) itself without exchanging the whole lamp assembly (10) including the housing (16) and the guiding element (22). Since the correct position of the bright/dark-cutoff may be provided by the entrance window (20) and/or the guiding element (22) only, a misalignment of a newly inserted LED (12) does not affect the correct position of the bright/dark-cutoff. The exchange of a LED (12) is facilitated and without affecting the correct position of the bright/dark-cutoff.
