Ⅳ、Summarize

From UV LED discrete devices and integrated module two aspects carries on the analysis shows that, the transmittance (UV light), air tightness, from several aspects, such as electrical and thermal performance, inorganic packaging materials is better than the organic packaging materials. Therefore, the use of organic material for UV LED devices and module is only suitable for occasions with low requirements on power and life, etc., and based on the CMH encapsulation technology of inorganic UV LED devices and module can adapt to various occasions of printing industry.
