Abstract
An optical structure for a lighting device of a motor vehicle headlight is disclosed. The optical structure is paired with or is a part of the lighting device such that it modifies a light distribution produced by the lighting device. The optical structure (1) includes two, three or more optical structural elements. Each structural element has a light-scattering effect. A first proportion of the structural elements is formed in such a way that beams generated by the lighting device and impinging on this first proportion of the structural elements pass through the proportion of the structural elements. Each beam is refracted by the relevant structural element to form a first exit beam, to form a second exit beam, and to form at least one further exit beam.
