Abstract

A bottom-emitting nitride light-emitting device with enhanced light extraction efficiency is provided. The increased light output is provided by the reflector that redirects upward-going light towards the bottom output. A mesh contact area, in one form, spreads current across the entire carrier injection area without occupying the entire top surface of the device.
