Testing method for headlamps, and testing device

A quality testing method for a light source in a headlamp, wherein the light source contains a matrix of light pixels, the method comprising the steps of:

• controlling the light pixels according to a test procedure such that the light source emits light corresponding to a test pattern;
• recording the test pattern by an optical recorder;
• comparing the test pattern with a reference pattern with regard to brightness and/or color value;
• wherein in a first step, test patterns are generated in which the square light pixel arrays contain relatively few light pixels, and the test patterns are scanned and compared with a reference pattern, and
• when the test pattern differs from the reference pattern by more than a predefined threshold value, further test patterns are generated in a second step, in which the square light pixel arrays contain a greater number of light pixels than in the first step;
• and
• wherein an operating control signal is generated for each light pixel based on the comparison of the scanned test pattern with the predefined reference patterns, such that differences in adjacent light pixels with regard to brightness and/or color values are compensated for.
