| Abstract: | This paper designs a new type of UVC LED encapsulation structure.The structure can effectively improve packaging components’outer quantum well efficiency.Experimental tests show that compared with the market mainstream encapsulation structure,with the premise of the same UVC chip,the new UVC LED encapsulation structure produces 22%increase in radiation flux when test current is 60 mA and 35%increase when test current is 120 mA.Furthermore,the new encapsulation structure is helpful to solve the production bottleneck of difficult electroplating of copper cup on ceramic substrate and raise production efficiency of UVC ceramic substrates and decrease the cost of UVC LED encapsulation device. |
