<p>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.</p> |
