Gemäß der Erfindung sind zwei identisch ausgebildete, entgegengesetzt zueinander, auf diametral entgegengesetzten Seiten angeordnete Befestigungselemente 30 vorgesehen, welche je einen an der Baueinheit 16 befestigbaren Abschnitt 32 und einen an der handelsüblichen Elektroinstallations-Unterputzdose 2 (oder 102 oder 202) befestigbaren Abschnitt 34 aufweisen.According to the invention, two identically formed, oppositely to each other, arranged on diametrically opposite sides of fasteners 30 are provided, which each have a fastened to the unit 16 section 32 and have a on the commercial electrical installation flush-mounted box 2 (or 102 or 202) attachable portion 34.

Zuerst wird der eine Abschnitt 32 der Befestigungselemente 30 an der Baueinheit 16 mit Verankerungselementen (weiteren Befestigungselementen), vorzugsweise Schrauben 36 und darauf befestigbaren Muttern 38, befestigt. Vorher oder nachher werden die elektrischen Anschlusslemente 23 und 24 des Netzteils 20 der Baueinheit 16 mit elektrischen Netzspannungsleitungen verbunden, welche sich in der Unterputzdose befinden und zu einem elektrischen Stromkreis gehören, durch welchen das Netzteil 20 der Baueinheit 16 an Ortsnetz-Wechselspannung anschließbar ist. Wenn der elektrische Stromkreis durch einen Schalter angeschlossen wird, erhält das Netzteil 20 elektrische Ortsnetzspannung, wandelt diese in eine für die mindestens eine LED 18 verträglichere niedrigere Spannung, vorzugsweise Gleichspannung um, so dass die LED 18 Licht durch ihre Lichtdurchlassfläche 26 abgibt. Die Farbe des Lichtes ist abhängig von der Art der LED.First, the one portion 32 of the fasteners 30 to the assembly 16 with anchoring elements (other fasteners), preferably screws 36 and fastened thereto nuts 38, attached. Before or after the electrical Anschlußlemente 23 and 24 of the power supply unit 20 of the assembly 16 are connected to electrical power lines, which are located in the flush-mounted box and belong to an electrical circuit through which the power supply unit 20 of the unit 16 is connected to local AC power. When the electrical circuit is connected by a switch, the power supply unit 20 receives electrical mains voltage, converts it into a lower voltage, preferably DC voltage, which is more compatible with the at least one LED 18, so that the LED 18 emits light through its light transmission surface 26.
