Title
(DE) HALBLEITERLAMPE MIT KÜHLKÖRPER
(EN) SEMICONDUCTOR LAMP WITH HEAT SINK
(FR) LAMPE À SEMI-CONDUCTEUR MUNIE D'UN CORPS DE REFROIDISSEMENT
Abstract
(DE)
Halbleiterlampe (11), aufweisend einen Kühlkörper (12), an welchem vorderseitig mindestens eine Halbleiterlichtquelle (4) angeordnet ist und welcher mehrere seitlich zu der Aussparung (3) angeordnete und senkrecht ausgerichtete Luftleitkanäle (13, 14) aufweist, wobei die Luftleitkanäle (13, 14) mindestens einen ersten Luftleitkanal (13) und mindestens einen zweiten Luftleitkanal (14) aufweisen und der mindestens eine erste Luftleitkanal (13) eine größere Länge (L1) aufweist als der mindestens eine zweite Luftleitkanal (14).
(EN)
Semiconductor lamp (11), having a heat sink (12), at which at least one semiconductor light source (4) is arranged on the front side and which has a plurality of air guiding ducts (13, 14) which are arranged laterally with respect to the cutout (3) and are oriented perpendicularly, wherein the air guiding ducts (13, 14) comprise at least one first air guiding duct (13) and at least one second air guiding duct (14) and the at least one first air guiding duct (13) has a greater length (L1) than the at least one second air guiding duct (14).
(FR)
L'invention concerne une lampe à semi-conducteur (11) comportant un corps de refroidissement (12), sur lequel est agencée côté avant au moins une source de lumière semi-conductrice (4) et qui comporte plusieurs canaux de guidage d'air (13, 14) agencés latéralement par rapport à l'évidement (3) et orientés verticalement. Les canaux de guidage d'air (13, 14) comportent au moins un premier canal de guidage d'air (13) et au moins un deuxième canal de guidage d'air (14). Le ou les premiers canaux de guidage d'air (13) présentant une longueur (L1) supérieure à celle du ou des deuxièmes canaux de guidage d'air (14).
