Problems solved by technology

But it also has a relatively big problem, but it also has a relatively big problem, it cannot be hot-started, and frequent lighting and extinguishing will greatly shorten the service life; Fill the tube with xenon and a small amount of rare metals to prepare high-power HID xenon lamps. Although it can solve the problem of service life, the current xenon lamps have complicated processing technology and low pass rate, making it difficult to achieve mass production.

Embodiment Construction

[0018] A kind of preparation technology of high-power xenon lamp of the present invention, it comprises the following steps:

[0019] a. Prepare the arc tube of the xenon lamp, cut the cylindrical quartz tube into an appropriate length, the length range is 50-120mm, use the blowing equipment to blow the center of the quartz tube into the shape of the arc tube; use the connecting tube to connect the center of the onboard arc tube to the upper row Trachea; put the electrode into the two ends of the arc tube after burning hydrogen and cleaning, and adjust the distance between the electrodes with a projector; -1200℃, carry out dehydration purification; add rare earth mixture and mercury into the arc tube through the exhaust pipe; use the exhaust machine to vacuum the arc tube and fill it with xenon gas mixture; Tube sealing treatment; arc tube surface cleaning, polishing, electrical testing and inspection;

[0020] b. Use molybdenum wire to shape the arc tube support bracket acco...

Abstract

A technology of manufacturing a large power xenon lamp disclosed by the present invention is characterized by comprising the following steps of a, preparing an xenon lamp electric arc tube; b, shaping molybdenum wires into an electric arc tube supporting support according to the dimension requirements of different specifications, and electrically welding gettering sheets on the support; c, placing the electric arc tube with the support in a corresponding quartz outer tube, and using an outer tube clamping and sealing machine to heat the quartz tube to clamp and seal into a lamp tube; d, filling silica gel or lamp holder fixing powder in a lamp holder, and welding the clamped and sealed electric arc tube with a lamp pin or a lead; e, fixing the shaped electric arc tube on the filled lamp head, placing in a baking oven to heat to 90 to 150 DEG C to dry and detect. The technology of the preset invention is simple, is convenient to operate, and possesses a good popularization value.

Description

technical field [0001] The invention relates to the technical field of illumination, and more specifically relates to a manufacturing process of a high-power xenon lamp. 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 the ordinary civilian commercial power to about 23000V pulse oscillation electric energy through frequency conversion, and stimulates the xenon electrons in the quartz tube to dissociate through high-voltage oscillation to generate a jumping 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...
