摘要:
The electric high-pressure discharge lamp has tungsten electrodes (2) in a light-transmitting lamp vessel (1) which is closed in a gastight manner. The electrodes (2) comprise an emitter, preferably in the form of an inner coiled-coil (14), which is loosely retained in a cavity (12) of a basket (6) of the electrode (2). The inner coil (14) acts as a non-oxidic emitter. The lamp retains its initial light output to a high degree throughout its life.
