光源:
1、光源采用8支額定功率為40W的紫外熒光燈作發(fā)光源。紫外線熒光燈 管,分布在機(jī)器的兩側(cè),每側(cè)各4支。有UVA-340和UVB-313光源供用戶選擇配置。(任選一種)
2、UVA-340燈管的發(fā)光光譜能量主要集中在340nm的波長處
3、UVB-313燈管的發(fā)光光譜主要集中在313nm波長附近。
4、由于熒光燈光能量輸出會隨時間而逐步衰減,為了減小因光能量衰減造成試驗的影響,所以本試驗箱在所有的八支燈管中每隔1/4的熒光燈壽命時,由一支新燈管替換一支舊燈管,這樣,紫外光源始終由新燈和舊燈組成,從而得到一個輸出恒定的光能量。

Light Source:
1, Using 8pcs UV fluorescent lamps with 40W power rating as light source. UV fluorescent tubes are distributed on both sides of the machine, each side has 4pcs. It has UVA-340 and UVB-313 optional for customers’ configuration. (Option one type)
2, UVA-340 lamp luminescence spectra energy is mainly concentrated in the 340nmof wavelength.
3, UVB-313 lamp luminescence spectra is mainly concentrated near the 313nm of wavelength.
4, Due to fluorescent light energy output will gradually decay over time, in order to reduce the test effect because of light energy attenuation, when in every 1/4 of the fluorescent lifetime of eight lamps in the chamber, a new lamp will replace an old lamp, thus UV light source is always formed by new lamp and old lamp, to get a constant output of light energy.
5, the effective useful life of the lamp is about 500 hours (imported one is about 1600~1800 hours).Standard: GB/T14522-93 GB/T16422.3-1997 GB/T16585-96; and other current UV aging test standards.
