Abstract:
The invention describes an array of light sources comprising multiple VCSELs arranged laterally to each other on top of a substrate, wherein each VCSEL comprises a light emitting area surrounded by an electrode structure which does not emit light, wherein a shielding layer is applied on top of at least the electrode structure only covering a surface (of the electrode structure facing towards an average light emitting direction of the VECSELs, the shielding layer is an opaque layer and being adapted to optically match the array in a switched-off state to an outer surface of a housing of a device, where the array of light sources is to be installed. The invention further describes the device comprising such an array and a method for manufacturing an array of light sources.
