HIGH-VOLTAGE DISCHARGE LAMP, HIGH-VOLTAGE DISCHARGE LAMP DEVICE, AND LIGHTING DEVICE

摘要

A high-voltage discharge lamp comprising: electrode-integrated feeder conductors (2) each having a sealing portion (2a) and a halide-resistant portion (2b) of which the root is connected to an end of the sealing portion (2a), which is inserted into a small-diameter cylindrical portion (1b) of a light-transmitting ceramic discharge enclosure (1) with a small gap between the halide-resistance portion (2b) and the inner surface of the small-diameter cylindrical portion (1b), and of which the end protrudes into a swollen portion (1a) of the light-transmitting ceramic discharge enclosure (1) to form an electrode (2c); and ceramic-sealing compound seals (3) for sealing the gaps between the small-diameter cylindrical portions (1b) and the sealing portions (2a) of the feeder conductors (2) integral with the electrodes.
