Abstract
Die hier beschriebene Natriumhochdruckentladungslampe mit kleiner Leistung zeichnet sich durch einen sehr hohen Xenonkaltfülldruck von mindestens 1 bar aus. Das Druckverhältnis zum Natriumbetriebsdruck liegt zwischen 10 und 30. Damit lassen sich bei einer Lampenleistung von 50 bis 100 W Lichtausbeuten von etwa 100 lm/W und mehr erzielen. The low-pressure sodium high-pressure discharge lamp described here is characterized by a very high xenon cold filling pressure of at least 1 bar. The pressure ratio to the sodium operating pressure is between 10 and 30. With a lamp output of 50 to 100 W, light yields of around 100 lm / W and more can be achieved.
