Method of operating an optoelectronic component, method of manufacturing an optoelectronic component, optoelectronic component, and illumination device

A method of operating an optoelectronic component, wherein the optoelectronic component comprises a pixel array with a plurality of optoelectronic semiconductor emitters/chips, a temperature sensor, and a driving circuit, wherein the temperature sensor is in thermal contact with the pixel array, including the following steps:

• Read-out of a temperature using the temperature sensor;
• Determining an operation parameter of the pixel array, wherein the operation parameter includes an image to be displayed by the pixel array;
• Estimating of a temperature difference between the temperature read-out from the temperature sensor and a junction temperature of a pn-junction of the pixel array based on the operation parameter and a model of the pixel array, wherein the temperature difference is different for at least two values of the operation parameter;
• Adding the temperature of the temperature sensor to the temperature difference;
• Comparing the sum of the temperature of the temperature sensor and the temperature difference to a maxi-mum junction temperature;
• Reducing of the power of the pixel array when the sum of the temperature of the temperature sensor and the temperature difference exceeds the maximum junction temperature.
