Abstract
A discharge lamp (20) for providing visible and/or infrared radiation comprising a stationary light transmitting bulb (21) filled with a composition that emits light when in plasma state, a radiofrequency source (41) having an output terminal (44) radiating a radiofrequency field for ionizing and heating the composition in the bulb to bring it in a plasma state (35), and a dielectric rod (22) aligned with the output terminal and positioned between the output terminal (44) and the bulb (21) acting as dielectric waveguide for the radiofrequency field.
