Abstract: The present invention relates to a LED light source comprising at least one layer of light emitting material (3), in particular organic light emitting material, sandwiched between two electrode layers (2, 4). At least one of the electrode layers (2, 4) is structured to form a pattern of electrode segments (5), each electrode segment (5) being in electrical contact with at least three of its nearest neighbor electrode segments (5) via direct electrical connections (6), which are designed to act as electrical fuses between the electrode segments (5). The invention allows the design of a large area LED light source having a homogeneous light density without the risk of failure of larger light emitting areas.
