d in laboratory tests to accelerate the aging time of samples.But one common problem with these aging tests is that they can only simulate one of the full spectrum light waves, such as 300-400nm.It has to be mentioned here that metl halogen lamp aging, that is, full spectrum sunlight simulation aging test.This is the closest aging method to sun light, with a radiation band range of 280-3000nmm. Irradiance: 600~1200W/m2. It can usually be used to make materials, parts or the aging of the full car
