Abstract

The present invention provides a long-arc type discharge lamp, which has a pair of electrodes arranged oppositely in an elongated UV-transmissive light-emitting tube. Rare gas and metals used as light-emitting substance are sealed into the elongated UV-transmissive light-emitting tube. In an AC-lighting long arc type discharge lamp containing a rare earth oxide in the aforementioned electrode, long time stable lighting is obtained by suppressing the draining of an emitter (electron emission substance) in the early stage, and preventing melanism and nebula of the light-emitting tube. The long arc type discharge lamp is characterized by: when the average value of lamp current is set to I (ampere: A) and the volume from an electrode tip to 3 mm is set to V (mm3), 0.4 ≤ (I/V) ≤ 1.0.
