Problems solved by technology

If the heat inside the LED cannot be effectively dissipated, the temperature of the LED will rise, deteriorating the reliability of the LED
On the other hand, if the light generated by the light-emitting diode cannot be effectively extracted, part of the light will be reflected or refracted inside the light-emitting diode due to total reflection factors, and will eventually be absorbed by the electrode or the light-emitting layer, so that the brightness cannot be improved.
