Description

Xenon flash lamp {XENON FLASH LAMP}

Embodiments of the present invention relate to xenon flash lamp technology.

In general, a xenon lamp is a lighting device that provides practically usable light with ultraviolet rays and visible rays generated by a discharge tube, which is a plasma generating means inside the bulb, while using xenon gas without using mercury vapor. Compared to other lighting devices, the xenon lamp emits light closest to natural light, is eco-friendly because it does not use mercury, and has the advantage of being able to easily adjust the luminous intensity, so it is applied in various fields.

Xenon lamps have several MW of power at the time of light emission, and if the lamp is repeatedly used with several MW of instantaneous power, the temperature of the wires and tungsten pins naturally rises as well. In general, the allowable current of the wire is several tens A, but the xenon flash lamp is instantaneous, but generates a current of several hundreds to thousands of A, which inevitably increases the temperature of the wire. When the temperature rises above 200 to 300 degrees Celsius, oxidation and deterioration occur in the wires and wire connections, which shortens the life of the lamp.
