Title:
HEADLIGHT AND HEADLIGHT ELEMENT
Document Type and Number:
WIPO Patent Application WO2004088200
Kind Code:
A3
Abstract:
The invention relates to a headlight comprising a plurality of headlight elements which respectively comprise at least one semiconductor chip emitting electromagnetic radiation; a primary lens element reducing the divergence of an incident light passing through a light input; at least one headlight element output which is used to radiate part of the light of a headlight from the headlight element. At least one of the headlight element outputs is arranged in at least two groups such that the arrangement of at least one group and/or at least the overall arrangement of the headlight element outputs corresponds essentially to a desired radiation characteristic of the headlight, such that in particular a form arises substantially corresponding to the cross-sectional shape of a desired headlight beam, whereby the semiconductor chips belonging to the headlight element outputs of one group can be respectively operated independently from the other semiconductor chips. The invention relates to a headlight element which is suitable for use with said type of headlight.
