Irradiation control of xenon lamp aging test chamber


<?xml:namespace prefix = o />

Any type of xenon lamp tube is attenuated over time. The xenon lamp aging test chamber for QINSUNcircle is compensated for use in a feedback loop control system. With this system, the operator can preset the irradiance value, and the irradiance sensor in the test chamber performs measurement of the light. When the lamp aging causes an output attenuation, the system will be automatically compensated by increasing the power of the xenon lamp. In theory, the light intensity can monitor any position of the xenon spectrum. But usually use only a few of several bands. The irradiance control is typically performed in the sensitive spectral area (for example, an area that is expected to occur). In addition, the irradiance control point is also changed due to the different industries.

340 nm The control point is widely used in accelerated aging test, for outdoor durability The aging test of sexual products, the risk of short-wave ultraviolet areas. 340 nm The control requires an ultraviolet sensor equipped with a filter, which is only allowed by a narrow band centered on 340 nm

. . Typically, thisan ideal control point for coatings, plastics, roof materials, etc..

ZUI of Control points is or m2 / nm @ 340 nm. 420N M The control point is generally supported with the window glass filter for the indoor light stability test of the material. Control 420 nm requires an ultraviolet sensor equipped with a filter, which only allows ultraviolet narrowband centered on 420 nm . The object testing of the system is usually for those major long wave ultraviolet rays andDamaged materials, such as dyes and pigments, paper and inks in knitted. ZUI of

, the set point is 1.10W / m2 / nm @ 420nm . flat panel and rotary drum type xenon lamp aging test chamber is usually installed 340 nm or 420 nm narrowband irradiance control system.In summary, flat and rotary drums xenon lamp aging test chambers have, equal amounts of feedback loop irradiance control systems.It is recommended that the lamp will reduce the effects of lamp aging.By using the sensor of 340 nm 340 nm or or or or


, or , it will be further reduced..
