what kind of light the museum lighting needs?

      Museum store a lot of exhibits, through regular exhibitions open to the audience. In the process of the  exhibitionsthe role of lighting is very important, on the one hand,it needs to be fully comprehensive display exhibits,on the other hand , it can not damage exhibits.

       During heritage show, visible light is what we need, others are not needed, however, both natural light and artificial light including many unwanted and harmful light, such as ultraviolet light, infrared light...



      Infrared light irradiate on the product, can cause the product become brittle or split,so it is harmful.

      Treatment ultraviolet and infrared light is very simple, with filters can be filtered. Of course, if it is a low color temperature of the LED light source, substantially free of  ultraviolet and infrared light, you need do nothing.

       However, if dispose of infrared light and ultraviolet light, do  exhibits safe and no hurt? 

       The answer is no!

       In addition to infrared light and ultraviolet light,we also need to pay attention to visible radiation, because it do damage to the exhibits too.

       First, many artifacts are "die in the spotlight", in particular light-sensitive Heritage,Including silk, cotton, embroidery, books, mural, painted sculpture, Leather, specimen...
