文摘
- •
A novel method for enhancing LEE of COB packaging LEDs is proposed.
- •
The method relies on the micro-lens array fabricated by ion wind.
- •
The diameter and gap of the micro-lenses are controlled by adjusting the voltage.
- •
The LEE of COB is controlled by the diameter and gap of the micro-lenses.
