Abstract
A light emission module, in particular for a motor vehicle. The module includes a substrate comprising a curved main portion extending in a longitudinal direction. A plurality of electroluminescent elements is arranged on the substrate and configured to emit light rays when supplied with electrical energy. The electroluminescent elements are distributed along the longitudinal direction, and a control assembly suitable for regulating the electrical energy supplied to the electroluminescent elements. The control assembly has a mode of operation in which the control assembly is configured to supply the electroluminescent elements with respective electrical energies and/or powers determined at least as a function of respective main directions of light emission of the electroluminescent elements to obtain at least two maximum light intensities emitted by the electroluminescent elements in the corresponding main direction of emission which are different along the longitudinal direction of the substrate.
