Patent ID: 7026659

Claim:
A light emitting diode comprising: a substrate having first and second opposing faces, that is transparent to optical radiation in a predetermined wavelength range and that is patterned to define, in cross-section, a plurality of pedestals that extend into the substrate from the first face towards the second face; a diode region on the second face that is configured to emit light in the predetermined wavelength range into the substrate that is transparent to optical radiation in the predetermined wavelength range, upon application of voltage across the diode region; a mounting support on the diode region opposite the substrate that is transparent to optical radiation in the predetermined frequency range, the mounting support being configured to support the diode region such that the light that is emitted from the diode region into the substrate that is transparent to optical radiation in the predetermined wavelength range, is emitted from the plurality of pedestals, upon application of voltage across the diode region; a reflector between the mounting support and the diode region, that is configured to reflect light that is emitted from the diode region back into the diode region, through the substrate that is transparent to optical radiation in the predetermined wavelength range and from the plurality of pedestals, upon application of voltage across the diode region; and a transparent electrode between the diode region and the reflector.
