Qinsun Si4000 Xenon lamp aging test chamber
Si4000 lamp power is 6500W. In the natural aging environment, the sample is mainly irradiated by light with a wavelength between 300-800nm. Si4000 can choose 340nm, 420nm and 300-400nm as monitoring points to control the radiation intensity there. During the test, in order to ensure the reproducibility of the test results ① , it is necessary to keep the parameters of the test process constant, and the irradiance intensity of the light source is the main control parameter. In order to overcome the influence of lamp attenuation and voltage instability on the irradiance intensity, Si4000 measures the irradiance intensity of the monitoring point through the light sensor, and after comparing the obtained result with the set value, the lamp power is closed-loop controlled by adjusting the current. , to ensure that the irradiation intensity of the sample is always constant. The American standard for outdoor aging mostly uses 340nm as the monitoring point; the American standard for indoor aging mostly uses 420nm as the monitoring point; the European standard uses 300-400nm both indoors and outdoors. It is recommended to use 340nm as the first monitoring point and 420 as the second monitoring point in the host. During a certain test, both monitoring points can be monitored, but only one of them can be controlled. In addition, we recommend purchasing a 300-400nm optical filter device. When the 300-400nm monitoring point needs to be used, the user can modify it by himself, and the host will automatically recognize it after modification. Generally, when the inner and outer filters are borosilicate glass, the reading at 340nm is multiplied by 115, which is the radiation intensity in the 300-400nm range. The test machine can control the length of the test time by accumulating the radiation energy.
