Abstract

The development of power-LED needs to improve its light extraction efficiency

secondary optical design based on microlens array is a effective way for improving light extraction efficiency. A packaging structure of high-power LED was presented

microlens array was employed in the secondary optical design

optical properties of the package was studied using Trace Pro. The results showed that microlens array technology can significantly improve the optical performance of the LED and increase light extraction efficiency

illumination attenuation of LED can be reduced by more than 12%

the results are satisfactory.
