Xenon lamp and manufacturing process thereof

Abstract

The invention discloses a xenon lamp and a manufacturing process thereof. The xenon lamp comprises a lamp cap, a lamp tube jacket and a luminous tube therein, wherein the end of the lamp tube jacket is provided with a pressure sealing port, two electrode leads of the luminous tube pass through the pressure sealing port, and the two electrode leads are connected with a molybdenum plate respectively. The xenon lamp is characterized in that: the molybdenum plates of the two electrode leads are staggered and fixed at the pressure sealing port and the cavity of the lamp tube jacket respectively, the molybdenum plate positioned in the cavity of the lamp tube jacket is sleeved with an insulating sleeve, and the insulating sleeve is downwards extended and passes through the pressure sealing port together with the electrode lead for connecting the molybdenum plate therein. The xenon lamp effectively prevents arcing and striking fire when two electrodes in the tube are started, and prevents high-voltage leakage during starting; the stability of the HID xenon lamp is improved; and the manufacturing process is convenient and has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of illumination, and more specifically relates to a xenon lamp and a manufacturing process thereof. Background technique [0002] HID (High Intensity Discharge) high-pressure gas discharge lamp, also known as xenon lamp, its working principle is in (UV-CUT) anti-ultraviolet crystal quartz glass tube, filled with inert gases such as xenon (XENON) and iodide, and then stabilized Supercharger (also known as supercharger), which instantly supercharges ordinary civilian commercial electricity to pulse oscillation electric energy of about 23000V through frequency conversion, and stimulates the xenon electrons in the quartz tube to dissociate through high-voltage oscillation to generate a jump arc between the two electrodes to complete the lighting. process, and then provide a square wave voltage with a pulse width period of 2.38 milliseconds that can adapt to the tube pressure of the lamp tube to maintain the norm...

AI Technical Summary

Problems solved by technology

But it also has a relatively big problem, it cannot be hot-started, and frequent lighting and extinguishing will greatly shorten the service life; Metal, made of HID xenon lamps that can be used with xenon lamp ballasts powered by ordinary civilian mains. Although it can solve the problem of service life, because the voltage of HID xenon lamps is above 20,000V when starting, if a screw or snap-in Install and fix the HID xenon lamp in the same way, the HID xenon lamp will produce arc discharge, that is, the common ignition phenomenon, so that the lamp cannot work normally, and for the HID xenon lamp with single-ended metal halide lamp structure, the high temperature and high pressure between the cathode and the anode Arc discharge phenomenon is easy to occur in the environment, which will damage the HID xenon lamp and affect the service life of the lamp tube
