Xenon lamp aging test box xenon lamp becomes yellow and black is what causes
We all know that the xenon lamp in the xenon lamp aging tester is very important, the xenon lamp is also its consumables, the normal use is in about 1200 hours. Xenon lamp aging chamber is divided into water-cooled and air-cooled cooling two ways, water-cooled need to use the water source, while the water quality and water flow is very important, the water quality is not good or insufficient water flow, will cause the xenon lamp yellow and black.
1. water-cooled xenon lamp aging tester is a high-pressure inert gas xenon gas as a discharge medium and excitation of light-emitting lamps, the structure of the coaxial inner and outer tube, the inner tube for the xenon lamp wick, the inner tube and outer tube with cooling water. Xenon lamp and the suns spectrum is similar to the long-arc water-cooled DC xenon lamp can be dimmable from 1-100, its spectral distribution and color temperature is basically unchanged, can be used in color inspection, fabric coating aging, solar cell testing, photochemical reactions and many other fields.
2. long-arc water-cooled xenon lamp is a high-pressure discharge lamp, so it should be taken lightly to prevent impact. In the installation and commissioning, staff should wear protective masks and gloves to prevent ultraviolet light burns skin and eyes.
3. long-arc water-cooled xenon lamp installation position horizontal and vertical can be. Special attention: DC xenon lamp anode volume is large cylindrical to receive positive electricity, DC xenon lamp cathode volume is small conical to receive negative electricity, electrodes are strictly prohibited to reverse, reverse xenon lamp soon scrapped. When connecting the xenon lamp electrode leads, do not make the xenon lamp head under pressure, so as not to break the xenon lamp head.
4. with the long-arc water-cooled xenon lamp supporting the power supply, to take the current ripple coefficient is low, the start of a small inrush current power supply, in order to ensure and extend the life of the lamp.
