The invention relates to a light source (L) for a sensor unit of a position measuring device. The light source (L) comprises an electrically conductive base layer (1) having a first face (1.1) and further faces (1.2 to 1.6), at least one of the further faces (1.2 to 1.6) being arranged obliquely or offset with respect to the first face (1.1), and a semiconductor layer structure (2), the semiconductor layer structure is applied to the first side (1.1). Furthermore, the light source (L) comprises an electrically conductive layer (3, 30), which is in contact with the base layer (1) on at least one of the further faces (1.2 to 1.6), and a first electrical connection (4) and a second electrical connection (5). The first electrical connection (4) is connected to the electrically conductive layer(3, 30) and the second electrical connection (5) is connected to the semiconductor layer structure (2), and wherein the two connections (4, 5) are arranged on a first side (S) of the light source (L). 本发明涉及用于位置测量机构的传感器单元的光源（
