Abstract
We studied the coating technology, research shows that: to coat the internal structure of coupler we need to consider both intensity problem and heat dissipation problem. For instance: thicker coating will increase the coupler’s resistance to stress and resistance to water vapor, but we will prefer a thinner coating because it is easier to let the light pass though and generate less heat. We’ve tried a number of different coating materials, and analyzed the adhesion during its curing process. Finally, according to the experimental results, we believe that cooling capacity needs to be first considered. Recent experimental results show that we can use advanced coupler coating technology to extend the working life of the coupler. At the end of paper, we provide a coating example and show its real contribution to the working life.
