ultraviolet led encapsulation

The encapsulation of ultraviolet led metal is import for uv led strip. there are has a variety kind for led encapsulation metal. such as:glass lens, epoxy resin and silicone resin.quarts glass having a relatively high softening point. the hot processing temperature as 1700~2000℃. from the technologic angle say—-the quarts glass are not good for uv encapsulation metal. the high temperature heat-resistance ability of epoxy resin is general. and it has less ultraiolet-resistance capacity.
Silicone is best choose for uv led ecapsulation.
