Abstract
Die Erfindung betrifft Schutzvorrichtungen zum Schutz von LED-Leuchtmitteln gegen Störimpulse. Die Schutzvorrichtung kann in ein Betriebsgerät (10), ein LED-Leuchtmodul (22) oder als separates Modul (30) ausgeführt sein und zeichnet sich aus durch eine mit den beiden LED-Anschlüsse verbundene Schutzschaltung (11) mit einer ersten Schutzkomponente (12), welche vorzugsweise spannungsbegrenzend wirkt, und mit einer zweiten Schutzkomponente (14; 13; 13A), welche die erste Schutzkomponente mit einem LED-Anschluss verbindet, wobei die erste Schutzkomponente (12), vorzugsweise unmittelbar oder über eine weitere Schutzkomponente (13B), mit dem anderen LED-Anschluss verbunden ist. Über einen Schutzanschluss bzw. Schutzleiter (16) ist zumindest die erste Schutzkomponente (12) mit einem Teil (18) in oder an einem Träger (17) des LED-Leuchtmittels, insbesondere ein Metallkern oder Kühlkörper, mit der Schutzschaltung (11) verbindbar ist, um störimpulsbedingte Überspannungen am LED-Leuchtmittel (2) zu begrenzen. The invention relates to protective devices for the protection of LED bulbs against glitches. The protective device can be embodied in an operating device (10), an LED lighting module (22) or as a separate module (30) and is characterized by a protective circuit (11) connected to the two LED connections with a first protective component (12). which preferably has a voltage-limiting effect and with a second protective component (14; 13; 13A) which connects the first protective component to an LED terminal, the first protective component (12) preferably directly or via a further protective component (13B) connected to the other LED connector. At least the first protective component (12) with a part (18) in or on a carrier (17) of the LED lighting means, in particular a metal core or heat sink, can be connected to the protective circuit (11) via a protective connection or protective conductor (16) to limit glitches caused by surges on the LED light source (2).
