The invention relates to a LED collimator element for a vehicle headlight with a low-beam function, which emits at least visible light of one color from at least one region of a light source. The LED collimator element ( 1 ) has at least one LED ( 2 ) as such a light source, whose predominant part of the light radiated in operation can be directly radiated in a radiation angular range of the LED collimator element ( 1 ), and comprises a collimator ( 3 ) deflecting the light which is not radiated in the radiation angular range of the LED collimator element ( 1 ) into the radiation angular range, wherein the LED collimator element ( 1 ) is asymmetrically structured at least regarding a collimator cutting plane ( 4 ) in such a way that a defined non-uniform brightness distribution is achievable in a radiation plane of the LED collimator element ( 1 ) defined orthogonally with respect to the collimator cutting plane ( 4 ) and with respect to a main direction of radiation of the LED collimator element ( 1 ), and at least one filter ( 12 ) is to be arranged at least in one region of the collimator ( 3 ) in such a way that, when realizing the low-beam function, the area of the traffic space, which lies below the bright-dark cut-off can be illuminated in defined areas with visible light of different colors.
