Abstract: In an embodiment a method for operating an optoelectronic semiconductor component includes providing the optoelectronic semiconductor component having an optoelectronic semiconductor chip and a casing comprising a matrix material, wherein the semiconductor chip is embedded into the casing, and wherein optically inactive particles have been introduced as crack nuclei into the matrix material of the casing, and operating the optoelectronic semiconductor component such that cavities form entirely within the casing for at least some of the crack nuclei.

Abstract: A method may include supplying electric power to a first light source and a second light source of at least two light sources by at least one ballast so that the first light source and the second light source emit a first source light and a second source light with a first and second spectral light distribution, respectively. The method further includes superimposing the first and second source light using an optical unit such that the lighting device outputs light with a spectral superposition light distribution. The method further includes detecting the light outputted from the lighting device using a light distribution sensor that provides a sensor signal corresponding to a spectral light distribution of the detected light. The method further includes comparing the sensor signal to a predefined spectral light distribution and adjusting the electric power supplied to the respective light source by the ballast based on the comparison.
