Abstract:
1. A headlight having a multitude of headlight elements, wherein each of the headlight elements comprises: (i) at least one semiconductor chip which emits electromagnetic radiation and has a chip output surface through which electromagnetic radiation is emitted, (ii) a primary optics element, which has a light input and a light output and which reduces the divergence of the light which is incident through the light input, with the light being at least part of the electromagnetic radiation and/or at least part of a secondary radiation which is produced from the electromagnetic radiation emitted from said semiconductor chip, and (iii) at least one headlight element output, which emits a part of the headlight light from the headlight element; and wherein at least some of the headlight element outputs are arranged in at least two groups in such a way that (a) the arrangement of at least one of the groups and/or (b) at least one overall arrangement of headlight element outputs of multiple groups corresponds essentially to a desired emission characteristic of the headlight, in that, in particular, it has a shape which corresponds essentially to the cross-sectional shape of a desired headlight beam, wherein the semiconductor chips which belong to the headlight element outputs of one group can each be operated independently of other semiconductor chips; and wherein each of the semiconductor chips is integrated into the headlight without a housing.
