Abstract

Die vorliegende Erfindung betrifft eine Leuchtdiodenlampe mit einer Vielzahl an Leuchtdioden (50), die aus einer begrenzten Anzahl an einfach herstellbaren Einzelteilen besteht und hohe Dichtigkeitsanforderungen erfüllt. Die Leuchtdiodenlampe umfasst einen Hohlkörper, eine Vielzahl an Leuchtdioden (50), die an der Außenseite des Hohlkörpers (2) angeordnet sind, und eine Schaltung, die im feuchtigkeitsdichten Innenraum des Hohlkörpers angeordnet ist. Zur Befestigung der Leuchtdioden sowie der Schaltung sind auf der Innen- und Außenseite des Hohlkörpers Nuten und Stege vorgesehen, in die die Leuchtdioden und die Schaltung eingeschoben sind. Die Erfindung betrifft weiterhin eine Schaltung für die Leuchtdiodenlampe, um einen gedimmten Betrieb oder gepulsten Betrieb bei maximaler Helligkeit zu ermöglichen, ohne die Lebensdauer des Leuchtmittels zu verkürzen.
