In the case of the embodiment of the distributor ring 12 shown here with only one outlet nozzle 14 in the center, it is preferable to ensure that the light emitted by the first lighting means 9 during operation of the lamp 1 is not covered by the outlet nozzle 14 or by the holder 16 and thereby virtually shadowed becomes. This impairment can be avoided that the holder 16 is transparent.
