ABSTRACT:
The method for assembly of an LED lighting device comprising an LED module and a reflective and/or refractive optical unit and provided particularly as a reading or seat light for use in a vehicle such as, e.g., an airplane, a train or a bus, comprises the following steps:providing an LED module (12) comprising at least one LED (22),providing a reflective and/or refractive optical unit (14) for illuminating a measuring plane by use of electromagnetic radiation from the LED module (12) and with the aid of said optical unit,arranging the optical unit (14) and the LED module (12) for later fixation to each other,driving the LED module (12) to cause it to emit electromagnetic radiation for illuminating a measuring plane,detecting at least a part of the electromagnetic radiation of the LED module (12) that is incident on the measuring plane, by use of a detector (18),moving the LED module (12) relative to the optical unit (14) and/or the optical unit (14) relative to the LED module (12) along the optical axis (16), until the detector (18) detects electromagnetic radiation of the LED module (12) of a presettable intensity, andfixing the optical unit (14) and the LED module (12) relative to each other in their current relative positions.
