Abstract

The invention relates to a lighting device (1), comprising a substrate (2), wherein the substrate (2) is populated with several semiconductor light sources (4), in particular arranged in a row, which semiconductor light sources (4) are covered by a partially reflecting transparent cover (6), and the substrate (2) has, in addition to the semiconductor light sources (4), at least one color change region (7-11; 16-17, 19) covered by the cover (6). A method is used to produce the lighting device (1) according to one of the preceding claims, wherein the method comprises at least the following steps: measuring a color deviation of a semiconductor light source (4); and, if a significant color deviation is detected, applying a color change region (7-11; 16-17, 19), which is adapted at least to the measured semiconductor light source (4), to the substrate (2).
