In 1948, when Mr. Wang returned to China, the old China had only small workshops and some capable craftsmen to repair or assemble the optical instruments on the guns. At that time, the only optical factory is in Kunming, Yunnan, named after the state-owned 298 factory, about 500to 600 people. They mainly serviced for weapon and guns, can make some simple military optical instruments, such as binoc...

(conyinute UV LED Reliability Research (Ⅰ)) 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 device...

Abstract UV LED Light Source, compared with the traditional UV light source, has the advantages of environmental protection, low power consumption and band selection. The application of UV LED in printing industry always has many challenges, its reliability issue is particularly acute. The organic materials have the properties of poor UV resistance and high permeability, which the deterioration of...
