| 摘要 |
The invention relates to a high-pressure gas discharge lamp which comprises at least a lamp bulb ( 1 ) hermetically enclosing a discharge space ( 21 ) filled with a gas, a functional layer ( 3 ), and a light emission opening ( 5 ), the latter two being arranged on the outer surface of the lamp bulb, wherein a second layer ( 4 ) covers further regions of the surface of the lamp bulb which do not serve the purpose of the functional layer, while the lamp can be operated at a power such that, given the power level of the lamp, a devitrification of the lamp bulb ( 1 ) and a condensation of the gas are substantially prevented.
