Abstract (en)
[origin: US2010194264A1] A high-pressure discharge lamp may include at least one discharge vessel; and two electrodes, which extend into a discharge space of the discharge vessel and between which a light-emitting discharge arc is formed during operation of the high-pressure discharge lamp, wherein a partial coating is applied to a circumferential surface of the lamp in the region of an end section, on the discharge space side, of at least one of the electrodes, said partial coating changing the luminance and color temperature of the emitted light.
