- the first is to increase the total amount of light produced by the chip
- the second method is to increase the so-called light extraction efficiency by extracting the generated light out of the LED as much as possible.
- the encapsulant surrounds the LED chip, but only about 15% of the chip generated light energy is output as light, and the rest is absorbed by the encapsulant.
