HIGH-PRESSURE DISCHARGE LAMP

摘要

The invention relates to a high-pressure discharge lamp intended for use in.assjmilation lightning. According to the invention, the high-pressure discharge lamp has a discharge vessel with a long axis (10), enclosing a volume V wherein an ionisable filling comprising a buffer gas and an excess amount of metal halide, which is selected from LiI, NaI and CaI2, is present, the discharge vessel having a inflated shape wherein at least the ends are non-cylindrical and curved towards the long axis at both ends, with an inner wall area A for which it holds that A/V < 6.6.
