Xenon lamp

Abstract

The invention discloses a xenon lamp. The xenon lamp comprises a discharging container consisting of quartz tubes; the discharging container is provided with a luminescent part and side tube parts, wherein the side tube parts are continuously extended from the two ends of the luminescent part, and a closed discharging cavity is formed in the luminescent part and is filled with inert gases; two opposite electrodes protrude into the discharging cavity, the electrodes protruding into the discharging cavity are in spiral shapes and are oppositely arranged at the two ends of the pipe axis of the discharging cavity. The distances between the electrodes of the xenon lamp and the pipe axis of the discharging cavity are moderate, the spotlight property and optical quality of the xenon lamp are good, and the electrodes are in spiral shapes, so that the breakdown area of the inert gases can be beneficially increased, so as to increase the quantity of light and improve the luminous efficiency of the xenon lamp; and furthermore, a molybdenum piece is arranged in the closed cavity so that a joint is unlikely to be oxidized, so that the life of the xenon lamp can be improved.

Description

Technical field [0001] The invention relates to a lighting lamp technology, in particular to a xenon lamp. Background technique [0002] HID (High Intensity Discharge) high-pressure gas discharge lamp, also known as xenon lamp, its working principle is to fill the (UV-CUT) UV-cut crystal quartz glass tube with inert gas such as xenon (XENON) and iodide, and then stabilize A supercharger (also known as a supercharger), which instantly boosts ordinary civil commercial power to a pulse oscillation electric energy of about 23000V through frequency conversion conversion. After high-voltage oscillation excites the xenon electrons in the quartz tube to dissociate and generate a jump arc between the two electrodes to complete the lighting. During the process, a square wave voltage with a pulse width period of 2.38 milliseconds that can adapt to the tube pressure of the lamp tube is provided to maintain the normal light emission of the xenon tube. The color temperature of HID high-pressu...

Problems solved by technology

[0003] At present, the distance between the electrodes of xenon lamps on the market and the tube axis in the discharge cavity is relatively far, which affects the light-gathering performance and beam quality of xenon lamps, and most of the electrodes are linear, so that the light-emitting point and discharge efficiency are not very high.
