Abstract: A method of arranging a multiplicity of LEDs in packaging units includes defining a desired range for at least one photometric measurement variable for each of the packaging units; selecting an LED from the multiplicity of LEDs not yet arranged in one of the packaging units; measuring the at least one photometric measurement variable for the selected LED; equipping one of the packaging units containing fewer than N−1 LEDs with the selected LED; storing a measured value and a position of the selected LED in the packaging unit in a memory; repeating until the packaging units are equipped with N−1 LEDs; repeating and calculating the average value of the photometric measurement variable, equipping a packaging unit for which the calculated average value of the variable lies in a defined range with the selected LED; and storing the measured value and the position of the selected LED.
