Title
(DE) HALBLEITERLAMPE MIT KÜHLKÖRPER
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).
