How to manipulate the irradiance of the xenon lamp aging tester
Production and manufacture of xenon lamp aging tester, ultraviolet aging tester and other natural environment testing instruments, I explain for many customers xenon lamp aging machine irradiance of small knowledge, looking forward to the large number of people have assistance.
340nm measurement point is commonly used in accelerated high and low temperature, for outdoor performance indicators products of high and low temperature old said, short and medium-wave ultraviolet territory with risk sources. 340nm control requirements with a weapon has a filtering system of ultraviolet induction switch, it only allows a narrow individual stock band based on 340nm as the management office. Generally, this is a rationalized measurement point for industrial coatings, plastics, slope roofing materials, etc. A wide range of irradiance measurement point is 0.35 or 0.55W/㎡/nm.
The 420nm measurement point is generally used with window filtration system service facilities for raw materials in the house light stability testing. The control of 420nm requires a filtering system for the UV sensor switch, which allows only 420nm as the basis for the narrow band of UV at the management. The overall target of this system testing is generally this type of material that is important for damage caused by long-wave UV and precision light. Examples include natural materials and pigments in textile products, printing paper and ink printing. The broad irradiance set point for the house simulation simulation is 1.10W/㎡/nm.
Xenon aging testers are generally equipped with a fully automatic control system for 340nm or 420nm narrow band irradiance. Depending on the specifications of the different xenon lamp aging machine models. Some European test chambers can use a fiber optic broadband TUV (exhaustive UV, 300-400nm), or a very fiber optic broadband exhaustive irradiance sensor switch (280-800nm). Fiber broadband induction switch is not easy to make a relatively small change in UV manifestation, sensitivity is likely to give by the spectrum analyzer in the short-wave UV part of the controller of the key fusion system to cause difficulties.
Xenon lamp aging tester with, the same feedback opinion control circuit irradiance fully automatic control system. It is recommended to dismantle the led lamp on time will reduce the damage of led lamp aging. According to the use of the irradiance control at 340nm or 420nm induction switch, the amount of change of the spectrum analyzer in the unique area will be further reduced.
