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. The present invention relates to a light emitting diode lamp having a plurality of light-emitting diodes (50), which consists of a limited number of easily manufactured items and meets high tightness requirements. The light-emitting diode lamp comprises a hollow body, a plurality of light-emitting diodes (50) which are arranged on the outside of the hollow body (2), and a circuit which is arranged in the moisture-tight interior of the hollow body. To fasten the LEDs and the circuit grooves and webs are provided on the inside and outside of the hollow body, in which the LEDs and the circuit are inserted. The invention further relates to a circuit for the light-emitting diode lamp in order to enable a dimmed operation or pulsed operation at maximum brightness, without shortening the life of the light-emitting means.
