Abrégé
(DE)
Die Erfindung betrifft eine Beleuchtungsvorrichtung (1) mit mindestens einer Leuchtdiode (LED) und mindestens einem Kühlkörper (4) zur Kühlung der Leuchtdiode. Mindestens eine der Komponenten (3, 4) der Beleuchtungsvorrichtung (1), insbesondere der Kühlkörper (4), weist an zumindest einer freien Oberfläche zumindest in Teilbereichen einen Emissionskoeffizienten von mehr als 0,75, bevorzugt von mehr als 0,8, besonders bevorzugt von mehr als 0,9 auf.
(EN)
The invention relates to an illumination apparatus (1) having at least one light-emitting diode (LED) and at least one heat sink (4) for cooling the light-emitting diode. At least one of the components (3, 4) of the illumination apparatus (1), particularly the heat sink (4), has an emission coefficient of more than 0.75, preferably of more than 0.8, particularly preferably of more than 0.9 at least in sub-regions on at least one free surface.
(FR)
La présente invention concerne un dispositif d'éclairage (1) comprenant au moins une diode luminescente (LED) et au moins un corps de refroidissement (4) destiné à refroidir la diode luminescente. Au moins l'un des éléments (3, 4) du dispositif d'éclairage (1), notamment le corps de refroidissement (4), présente sur au moins une surface libre, au moins dans des zones partielles, un coefficient d'émission de plus de 0,75, de préférence de plus de 0,8, de préférence encore de plus de 0,9.
