Abstract

The invention relates to a light-emitting diode module for a vehicle headlamp, which has a carrier for a number of light-emitting diodes and which carrier has a lateral surface of axially symmetrical design relative to a longitudinal axis, a number of light-emitting diodes being arranged on the lateral surface of the carrier, and the carrier being provided with at least one light directing means in order to direct in directions transverse to the longitudinal axis of the carrier the light emitted by the light-emitting diodes.
