Abstract: According to the present disclosure, a method for operating an illumination apparatus is provided. The method has at least two light-emitting devices, which are arranged next to one another separated by a gap and each have a multiplicity of light-emitting elements, by individually driving all light-emitting elements of each light-emitting device, measuring a gap width of the gap and/or a luminance in the gap, and controlling or regulating in each case a luminance of one or more of the light-emitting elements which are arranged directly at the gap in dependence on the gap width and/or on the luminance in the gap.

Abstract: A method for adjusting a luminous intensity of headlamp light of a vehicle is provided. The vehicle includes at least one headlamp producing the headlamp light. The at least one headlamp includes a plurality of individually controllable light sources which create different partial areas of a light emission pattern of the headlamp light. The method includes obtaining a ground geometry of a ground area which can be illuminated by the headlamp light in the vicinity of the vehicle, calculating an illuminance producible by each of the light sources on the ground area using the obtained ground geometry, comparing the calculated illuminances with respective reference values, and adjusting a luminous intensity of the light sources to achieve the associated reference values of the illuminance.
