Abstract

An optoelectronic headlight which emits electromagnetic radiation is specified, which has a luminescence diode chip with at least two spatial emission regions or which has at least two luminescence diode chips each having at least one spatial emission region. The headlight is suitable in particular for a front headlight for motor vehicles. The emission regions, in a plan view of a main extension plane associated with them, are shaped differently, are of different sizes and/or are not shaped rectangularly and are differently oriented. Particularly preferably, the emission regions can be driven independently of one another. Methods for production of an optoelectronic headlight and a luminescence diode chip are furthermore specified.
