## 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.

## Claims

### Claim at position 1

1-15. (canceled)

### Claim 16

A method of arranging a multiplicity of LEDs in packaging units, comprising:
a) defining a desired value range for at least one photometric measurement variable for each of the packaging units, wherein an average value of the photometric measurement variable for a fixed number of N≧3 successive LEDs in the packaging units is intended to lie in the desired value range;
b) providing the multiplicity of LEDs and the packaging units;
c) selecting an LED from the multiplicity of LEDs which is not yet arranged in one of the packaging units;
d) measuring the at least one photometric measurement variable for the selected LED;
e) equipping one of the packaging units, containing fewer than N−1 LEDs with the selected LED, wherein the LEDs are strung together in the packaging unit in the equipping order;
f) storing a measured value of the at least one photometric measurement variable and a position of the selected LED in the packaging unit in a data memory;
g) repeating c) to f), until all of the packaging units are equipped with N−1 LEDs;
h) repeating c) and d) and calculating the average value of the at least one photometric measurement variable, which respectively results for the N−1 LEDs last arranged in the packaging unit and the selected LED, wherein the calculation is carried out for all of the packaging units;
i) equipping a packaging unit for which the calculated average value of the at least one photometric measurement variable lies in a defined desired value range with the selected LED, wherein the selected LED is arranged in the packaging unit such that it directly follows the LED last arranged in the packaging unit; or sorting out the selected LED if the calculated average value of the photometric measurement variable does not lie in the defined desired value range for any of the packaging units;
j) storing the measured value of the at least one photometric measurement variable and the position of the selected LED in the packaging unit in a data memory; and
k) repeating h) to j), until the packaging units are equipped with a desired total number of LEDs.
