Abstract
A light emitting diode is disclosed that includes a light emitting active structure formed from the Group III nitride material system, a bonding structure supporting the Group III nitride active structure, and a mounting substrate supporting the bonding structure. The mounting substrate includes a material that reflects at least fifty percent of light having the frequencies emitted by the active structure.
Claims15
A light emitting diode comprising:
- a light emitting active structure formed from a Group III nitride material system;
- a bonding structure;
- and
- a mounting substrate,
- a first ohmic contact to a p-type portion of said light emitting active structure;
- and a second ohmic contact to an n-type portion of said light emitting active structure,
- said mounting substrate comprising a material such that a surface of the mounting substrate reflects at least fifty percent of light having the frequencies emitted by said active structure, wherein said bonding structure is between said Group III nitride light emitting active structure and said mounting substrate.
