DEVICE FOR TESTING WEATHER/LIGHT-RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a device for testing weather/light-resistance capable of simultaneously projecting light with many different kinds of spectral distribution for testing in an identical test fixture and testing a lot of samples at a time using a simple facility without requiring the time for preparing the test.;SOLUTION: A polygonal tube-like filter body having a filter with selectivity for many kinds of wavelength is disposed between an inner filter and an outer filter in a lamp house, and a partition is disposed for dividing a space of a light source and a sample holder. A plurality of support bars for installing the partition are disposed on upper and lower rings of a sample holder support frame, thereby carries out the projection test at a time using the light with plural different kinds of spectral distribution.;COPYRIGHT: (C)2002,JPO
