Design and structure of pulse xenon lamp

Unlike flash tubes, pulsed Xenon Lamps must withstand not only average current but also higher peak current, so the design of their electrodes and seals is also very different from flash tubes. Quartz glass seals can only withstand an average current of about 15 to 25 amperes and a peak current of about 70 to 100 amperes. If the lamp is used as a high-power flash lamp, such seals will burn out like a fuse due to excessive peak current.

The design of the electrodes must be able to withstand an average current of about 15 amperes, which is very similar to the electrodes of mercury lamps. Solid tungsten rods with external tungsten wire windings must also be used as electrodes, and the windings are also coated with emitting materials.

The length of the quartz glass discharge tube varies, and the design load is about 50 watts per centimeter. The inner diameter remains roughly unchanged. The amount of xenon charged should be controlled according to the maximum discharge voltage that can be provided and adapted to the energy required to trigger the lamp tube every half cycle.
