The invention relates to a high-frequency lamp with a glass bulb and a device for supplying a high-frequency signal. High-frequency lamps known in the prior art either have been limited to a narrow selection of substances in the glass bulb or have relied on a heating process using a spiral-wound filament or the like. The aim of the invention is to provide an inexpensive and more efficient high-frequency lamp. This is to be achieved in particular in that the glass bulb is made, for example from window glass, so as to be heatable by the heat losses of the high-frequency signal in the glass bulb such that even metal halogenides for example can be evaporated without an additional heating process.
