Headlight projection module for a motor vehicle
ActiveCN103090286AIncrease designEasy to illuminateVehicle headlampsPoint-like light sourceStructural elementOptical pathlength
The invention relates to a headlight projection module (10) for a vehicle, which is used for generating preset light distribution. The headlight projection module (10) has a light source (11) for emitting light, a primary lens (12) for concentrating a part of the emitted light, and a secondary lens (14) for projecting a part of the concentrated light in a light emitting direction (3) of the projection module. In order to enable the headlight projection module (10) to realize maximally effective structure and to illuminate a non-circular secondary optical unit (14) as uniform as possible with the whole surface, it is suggested that an optically active micro-structure (24) that refracts light be arranged in the beam path of the concentrated light in a virtual object position of the secondary optical unit (14). The micro-structure (24) has dimensions of the function-determining structural elements (26, 27) in the micrometer range, especially a height difference of the single structural elements (26, 27).
