Abstract
A flash discharge lamp includes a pair of electrodes i.e. an anode and a cathode, oppositely disposed in at both ends of the glass bulb. An electro-conductive member is provided on the outer surface of the glass tube. A triggering electrode is mounted on the cathode and electrically connected to the electro-conductive member. Xenon gas is sealed in the glass tube. The flash discharge lamp further includes at least one High Temperature Resistant electrode mounted on the cathode and at least one Getter electrode mounted on the cathode and/or the anode. Not only can the above design increase the discharge output power and the discharge frequency, but it also extends the life expectancy of the flash discharge lamp.
