Abstract: The invention relates an optoelectronic-component having a pixel array with a plurality of optoelectronic semiconductor emitters/chips, a temperature sensor, and a driving circuit. A temperature is read out, using the sensor. An operation parameter of the pixel array is determined. Based on the operation parameter and a model of the pixel array, a temperature difference between the temperature read-out from the temperature sensor and a junction temperature of the pixel array is established. The temperature difference is different for at least two values of the operation parameter. The temperature of the temperature sensor is added to the temperature difference. The sum of the temperature of the temperature sensor and the temperature difference is compared to a maximum junction temperature. A power of the pixel array is reduced when the sum of the temperature of the temperature sensor and the temperature difference exceeds the maximum junction temperature.
