Natriumhochdrucklampe kleiner Leistung |
摘要 |
The low-power high-pressure sodium discharge lamp described here is distinguished by a very high xenon cold filling pressure of at least one bar. The pressure ratio relative to the sodium operating pressure is between 10 and 30. As a result, light efficiencies of approximately 100 lm/W and higher can be achieved for a lamp power of 50 to 100 W. |
