LED is revolutionizing humans lighting environments.  There have been timelines established to replace incandescent or fluorescent lamps worldwide.  However, the current white light LED is based on GaN semiconductor that is epitaxially deposited on either sapphire or SiC wafers.  Due to the non-equilibrium growth of GaN lattice on mismatched Al2O3 substrate, or defects ridden SiC, there are ample dislocations (e.g. 109/cm2) that may reduce the internal quantum efficiency of photon emission.  Worse still, the dislocations may propagate irreversibly upon heating.  This is why LED will dim with time.  In order to avoid LED chips from overheating, the heat blocking epoxy insulator on the circuit board is replaced by diamond like carbon (DLC).  The result is a dramatic decrease of the chip temperature.
