Abstract

Um bei einer ausfallsicheren Leuchte, insbesondere Leuchte für medizinische Anwendungen, mit Entladungslampe einen kontinuierlichen Lampenbetrieb auch bei einer Umschaltung zwischen einem Stromversorgungssystem (Niederspannungs-Versorgungssystem von z.B. 24 V) und einer zusätzlichen Sicherheitsstromversorgung (ZSV) zu ermöglichen, wird im Falle einer Störung der Stromversorgung für eine Versorgungseinheit der Leuchte durch Umschaltung auf eine Ersatzstromquelle oder nach Wegfall der Störung von der Ersatzstromquelle auf die normale Stromversorgung zurück ein Pufferspeicher entladen, welcher elektrische Energie für den Betrieb der Entladungslampe abgibt.In the case of a fail-safe luminaire, in particular a luminaire for medical applications, with discharge lamp continuous lamp operation even when switching between a power supply system (low voltage supply system of e.g. 24 V) and an additional safety power supply (ZSV) is possible in the case of a Fault in the power supply for a supply unit of the lamp by switching to a backup power source or after the failure of the backup power source to normal Discharge the power supply back to a buffer storage, which is electrical energy for the Operation of the discharge lamp emits.

Die der Versorgungseinheit (EVG) zugeführte elektrische Energie durchläuft zunächst einen Vollweg-Gleichrichter und wird dann einem Spannungswandler mit dem Pufferspeicher zugeführt, wobei nachfolgend die Entladungslampe über einen leistungsgeregelten Wechselrichter mit der elektrischen Energie versorgt wird.The electrical energy supplied to the supply unit (EVG) first passes through one Full-wave rectifier and is then fed to a voltage converter with the buffer memory, followed by the discharge lamp via a power-controlled inverter is supplied with the electrical energy.

Es ist somit sichergestellt, dass auch bei Umschaltvorgängen mit unterschiedlichen Stromarten - z.B. von Wechselstrom auf Gleichstrom - aufgrund der Leistungsregelung der Entladungslampe ein kontinuierlicher Entladungslampenbetrieb ohne Beeinträchtigung möglich ist. Bei Störung des Betriebes der Entladungslampe oder ihrer Eneregieversorgung wird ein Stromkreis zum Betrieb einer Halogen-Glüh-Lampe als Reserve-Lampe geschlossen.

Figure 00000001
It is thus ensured that even in the case of switching processes with different types of current - for example from alternating current to direct current - continuous discharge lamp operation is possible without impairment due to the power control of the discharge lamp. In the event of a malfunction in the operation of the discharge lamp or its energy supply, a circuit for operating a halogen incandescent lamp as a reserve lamp is closed.
