Embodiment Construction

[0078] Identical or identically acting components are provided with the same reference symbols in the exemplary embodiment and in the figures.

[0079] figure 1 The illustrated headlight part 2 includes a semiconductor chip 3 mounted on a carrier 12 . The support 12 is in turn mounted on a second support 15 which serves as a heat sink for the heat generated by the semiconductor chip 3 during operation.

[0080] Semiconductor chips are, for example, thin-film light-emitting diode chips, which are generally commercially available components. In addition, the epitaxial column is based on In x Al y Ga l-x-y or In x Ga y Al l-x-y At least one material in the P series, where 0≤x≤1, 0≤y≤1 and x+y≤1. It has a chip output coupling area 4 which is directly connected to the input light passage 17 of the primary optics.

[0081] For example, a fluorescence conversion material is coated on the chip output coupling surface 4 , which comprises, for example, one or more fluorescent ...

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.

Description

technical field [0001] The invention relates to a headlight and a headlight part. [0002] This patent application claims priority from German patent application 10314524.9, the disclosure of which can be incorporated into the present application. Background technique [0003] For example, US 6527411 B1 describes a headlight consisting of headlight parts. The output light passage of the headlight part or headlight parts themselves is circular, the central headlight part being surrounded by a number of other headlight parts. In particular, light-emitting diodes (LEDs) are used in such headlights, which have the advantage, for example, of long life, fast response and high electrical efficiency, which reduces maintenance costs and power consumption. [0004] However, the headlamp according to US Pat. No. 6,527,411 B1, due to its circular shape for multi-purpose use, cannot or is used to a limited extent when certain reflective properties of the headlamp are required. An exam...
