Large-power xenon lamp bulb and preparation method thereof

Abstract

The invention discloses a large-power xenon lamp bulb and a preparation method thereof. The large-power xenon lamp bulb comprises a bulb casing, the two sides of the bulb casing are each provided with a glass tube, the glass tubes are internally provided with molybdenum rods with molybdenum sheets, and the bulb casing is filled with xenon, a metal halide and mercury. The large-power xenon lamp bulb is characterized in that the glass tubes are provided with clamping sealing positions for fixing the molybdenum rods, and each molybdenum rod is provided with a limiting lamp pin abutting against the inner walls of the two sides of each glass tube. The structure is simple, the processing is convenient, the product surface temperature during work is uniform, the life is long, 360-degree light extraction is uniform, the transmittance is good, and the performance is better.

Description

technical field [0001] The invention relates to the technical field of xenon lamps, in particular to a high-power xenon lamp and a preparation method 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 normal light ...

AI Technical Summary

Problems solved by technology

Although the patented structure and process are not complicated, the biggest disadvantage is that the connection of the exhaust pipe cannot be achieved, and the thickness cannot be guaranteed to be consistent with other wall thicknesses, which may easily lead to uneven heating and excessive high temperature at the connection between thick and thin. And affect the service life; In addition, the uneven thickness will also affect the direction of light transmission, especially the burning tip after the exhaust pipe is sealed is particularly thick, resulting in the loss or obstruction of part of the light source, affecting the overall luminous efficiency
