| 摘要 |
The invention relates to a cooled high-pressure gas-discharge lamp, at least comprising a cooled envelope ( 43 ) that seals off hermetically a discharge chamber ( 431 ) filled with a gas, there being, at least in the discharge chamber ( 431 ), a non-uniform temperature distribution at the time of the gas discharge, and comprising a cooling means ( 7 ) having a coolant, which cooling means ( 7 ) produces a directed flow ( 9 ) of coolant, there being a liquid coolant acting on the envelope ( 43 ) of the lamp, it being possible for the lamp to be operated at a higher power, and the flow ( 9 ) of coolant being such that, when the power consumption of the lamp is increased, any devitrification of the envelope ( 43 ) of the lamp and any condensation of the gas is substantially prevented.
