Problems solved by technology

The disadvantage of this filling and exhausting method is that xenon is too wasteful and the utilization rate is too low
Because each time a batch of arc tubes is filled with xenon gas, the xenon gas left in the pipeline will be drawn out together with the air in the next batch of arc...

Embodiment Construction

[0014] Such as figure 1 As shown, the device of the present invention is composed of an inflation and exhaust system 9 and a recovery system 10 that can collect residual xenon gas. The inflation and exhaust system 9 is composed of four-way connector 1, arc tube arrangement pipe 8, pressure gauge 7 and electromagnetic valves 2, 3, 4. The pressure gauge 7 can display the vacuum degree in the inflation and exhaust system and the pressure of the inflated gas . The electromagnetic valve 2 is connected with the vacuum pump, the electromagnetic valve 3 is connected with the argon gas inlet, the electromagnetic valve 4 is connected with the xenon gas inlet, and eight arc tubes to be inflated can be placed on the arc tube arrangement pipeline 8 at the same time. The recovery system 10 is arranged at the tail end of the arc tube arrangement pipeline 8 and is composed of a cylinder 6 and an electromagnetic valve 5 , and the electromagnetic valve 5 is arranged between the arc tube arrang...

Abstract

The invention discloses a gas charge-discharge method and device capable of adequately using xenon gas, comprising: using a recovery system connected with a charge-discharge system in parallel to collect and store the xenon gas remained in the charge-discharge system as charging gas for next batch of arc tubes. The device is composed of a charge-discharge system and a recovery system for collecting the xenon gas. The charge-discharge system comprises a four-way connector, three valves respectively connected with the four-way connector, and a arc tube arranging pipe; three valves are respectively connected with a vacuum pumping device, a flushing gas inlet and a working gas (xenon gas) inlet; a plurality of arc tubes to be charged can be disposed on the arc tube arranging pipe simultaneously; the recovery system is disposed on one end of the arc tube arranging pipe, composed by a recovery device and a valve, the valve is disposed between the arc tube arranging pipe and the recovery device. The invention can effectively enhance the utilization rate of xenon gas during xenon gas lamp manufacture, by increasing the utilization rate from under existing 30% up to over 95%.

Description

technical field [0001] The invention belongs to the technical field of electric light sources, and specifically relates to a method and device for fully utilizing and recovering xenon gas charging and exhausting, which is suitable for the manufacture of automobile xenon gas headlights and other electric light source products using xenon gas as the working gas. Background technique [0002] Xenon lamps for vehicles have the advantages of instantaneous strong light output, energy saving, safety and long life, and are the development direction of automobile headlights. The xenon gas of about 6 atmospheres is filled in the vehicle xenon lamp as the starting gas. The existing filling method is to use a filling and exhausting system to alternately vacuumize and flush the impurity gas for several arc tubes arranged in a row. After the impurity gas in the arc tube is reduced to the process requirements, the working gas is charged through the charging and exhausting system, and the c...
