碩士 === 崑山科技大學 === 光電工程研究所 === 104 === The results showed that the relative light output of packaged UV LEDs, after dynamic stress at room temperature, 395 nm UV LED and 365 nm UV LED were 81.8% and 14.4%, respectively. According to the optical microscopy revealed the 395 UV LED, the encapsulated no cracking after the test, so we can understand the 365 nm UV LED Effect of the encapsulated largest. And then we study Reliability Test of 365 nm UV LEDs with Different Encapsulants, the results showed that the encapsulated under different colloidal behavior in the Series of O is higher than both the strength and hardness, and preferably maintained at room temperature, light output power, and in viscosity, Series of A and at a high temperature greater than both the It can have a better light output power.
