Abstract (en)

[origin: WO03056605A2] The invention relates to a cooled high intensity gas discharge lamp. Said lamp comprises at least a cooled bulb (43), which hermetically seals a discharge chamber (431) that is filled with a gas, whereby at the moment of discharge, an inhomogeneous temperature distribution is present, at least in the discharge chamber (431) and a cooling device (7) containing a coolant, which produces a directional coolant stream (9). According to the invention, a liquid coolant acts on the bulb (43), the lamp can be operated with an increased performance and the coolant stream (9) is formed in such a way that devitrification of the bulb (43) and condensation of the gas is substantially prevented during increased power consumption.
