Exhaust-pipe-free UPS pulse metal halide lamp

Abstract

The invention relates to an exhaust-pipe-free UPS pulse metal halide lamp, which comprises an electrode, a first clamp end which is used for clamping after the electrode is installed, an electric arc tube cell shell which is formed by a quartz tube through once forming and a second clamp end which is used for clamping after the electric arc tube cell shell is exhausted, wherein the electrode is arranged inside the first and the second clamp ends, the first clamp end is arranged on the left end of the electric arc tube cell shell, the second clamp end is arranged on the right end of the electric arc tube cell shell, and the first clamp end, the second clamp end and the electric arc tube cell shell are of an integrated structure. Since a cold end is not existed, the light efficiency is higher; the electric arc tube cell shell is free from reprocessing after being formed by the quartz tube at one time and can directly enter the following procedure to be produced, so the air leakage of the exhaust pipe is free from existing, the service life is longer, the energy can be saved, and the exhaust-pipe-free UPS pulse metal halide lamp is more energy-saving and more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of metal halide lamps, in particular to UPS pulse metal halide lamps without exhaust pipes. Background technique [0002] At present, UPS pulse metal halide lamps with an exhaust pipe structure are used in the international market. There are many shortcomings in the use of this structure of lamps, such as: the overall temperature distribution is uneven; at the exhaust pipe, There is a cold end, so that during the ignition process of the lamp, there will be metal halides deposited in the depression of the exhaust pipe, so that the metal halides cannot fully participate in the light emission, resulting in poor color temperature consistency and low luminous efficiency of the lamp; due to the existence of exhaust gas The reprocessing of the mouth, that is, after the arc tube bulb is formed once, an exhaust pipe is connected externally. Therefore, there is a possibility of air leakage at the exhaust pipe, so that...
