LED-Shunt-Schutzkomponenten (LSPs)

Spezifikationen

Zusammenfassung

Die Festkörperbeleuchtungsleuchten in LED-Beleuchtungsanwendungen bestehen häufig aus langen Reihen mit mehreren in Serie geschalteten LEDs, die über eine Konstantstromquelle mit relativ hohem Spannungsbereich versorgt werden.

Diese Konfiguration hat mehrere Vorteile:

Zur Vereinfachung des Stromversorgungsdesigns können mehrere LEDs in Serie angeordnet werden.
Die Hochspannung-Schwachstrom-Versorgung bietet eine erhöhte Effizienz.
Modulares Konzept ermöglicht die einfache Skalierung, beispielsweise mit 1-W-LEDs – aus mehreren Reihen mit 8 1-W-LEDs können einfach 16-W-, 24-W- oder 32-W-Ausführungen zusammengestellt werden.
Bei einer LED-Straßenleuchte kommen sechs Reihen mit je 15 LEDs, also insgesamt 90 LEDs, zum Einsatz.

Das LSP-Produkt ist darauf ausgelegt, Ausfälle durch eine unterbrochene LED-Kette zu verhindern. Fällt eine LED aus, erlischt eine vollständige LED-Kette, sodass die gesamte Beleuchtung unbrauchbar oder in ihrer Funktion deutlich eingeschränkt wird. Dies hat Rücksendungen und Reparatureinsätze zur Folge.

Zur Erfüllung der Energy-Star® Richtlinien müssen LED-Beleuchtungskörper:

eine Garantie von 3 Jahren haben;
>70 % Neulichtleistung für 35 Tsd. Stunden bieten (Wohnbereich: 25 Tsd. Stunden).

Während schwache LED-Ketten auf Zener-Dioden setzen können, würden leistungsstarke LEDs sehr große und teure Zener-Dioden benötigen. Mit einer LSP-Vorrichtung von Bourns® kann sichergestellt werden, dass die übrigen LEDs einer Reihe weiterhin funktionieren, wenn eine LED ausfällt. Aktive LSP-Vorrichtungen verbrauchen weniger Strom als die LED verbraucht hat.
