1. A lighting module comprising an elongated carrier and a flexible circuit;
wherein the flexible circuit comprises a first section accommodating a plurality of LED light sources, a second section and a connector;
wherein the connector is embedded in a circuitry of the flexible circuit and is accommodated in the second section for receiving power to power said plurality of LED light sources and for providing control commands to the plurality of LED light sources, wherein the connector extends at least partly in the first section;
wherein the elongated carrier comprises first end-face and a second end-face, and extending therebetween comprises a first elongated main surface and a second elongated main surface, the second elongated main surface being opposite to said first elongated main surface;
wherein the flexible circuit is folded around the second end-face, and wherein the second end-face comprises a recess, such that the fold is entirely comprised within the recess;
wherein the first section of the flexible circuit is connected to said first elongated main surface, and wherein the second section of the flexible circuit is connected to said second elongated main surface; and
wherein the elongated carrier comprises a cross-section comprising a curvature for improving the bending stiffness of the lighting module and for thereby reducing a deflection of the lighting module in its elongated direction.
