A xenon lamp energy adjusting system of a weather-resistant test box

Abstract

The invention discloses a xenon lamp energy adjustment system for a weather-resistant test chamber, which includes a programmable control module, an energy adjustment signal output module connected to the programmable control module in sequence, a power supply module, a xenon lamp trigger, and a long-arc water-cooled xenon lamp. The water-cooled xenon lamp is connected with a radiation intensity detector and an analog input conversion module, and the analog input conversion module is connected with a programmable control module, and the programmable control module is externally connected with a control terminal. The invention compares the measured radiation intensity with the set radiation intensity through the programmable control module, controls the energy adjustment signal output module to adjust the output power of the power supply module, and always controls the radiation intensity of the long-arc water-cooled xenon lamp Near the set value, the long-arc water-cooled xenon lamp is always maintained at a low level, which is lower than 40% of the rated power of the long-arc water-cooled xenon lamp, thereby prolonging the service life of the long-arc water-cooled xenon lamp and making the long-arc water-cooled xenon lamp life Over 2000 hours.

Description

technical field [0001] The invention relates to the technical field of environmental test equipment, in particular to a xenon lamp energy adjustment system for a weather-resistant test chamber. Background technique [0002] In the field of environmental test equipment, the tubular long-arc xenon lamp on the xenon lamp weather resistance test box is used to simulate the irradiation of sunlight, and is the core component of the test box. At present, the tubular long-arc xenon lamps used in domestic test chambers mainly fall into three categories: air-cooled DC xenon lamps, water-cooled DC xenon lamps and water-cooled AC xenon lamps. The life of the air-cooled DC xenon lamp is about 1000 hours, the life of the water-cooled AC xenon lamp is about 500 hours, and the life of the water-cooled DC xenon lamp is about 1000 hours. In many industries, it often takes more than 1000 hours to do a xenon lamp weather resistance test, so the test must be temporarily interrupted to replace t...

Problems solved by technology

In many industries, a xenon lamp weather resistance test often takes more than 1000 hours, so the test must be temporarily interrupted during the test to replace the lamp tube, which brings inconvenience to the user and compromises the test effect

A pressing problem is: must extend the service life of the xenon lamp
