摘要： A vertical light emitting diode (VLED) die includes an epitaxial structure having a first-type confinement layer, an active layer on the first-type confinement layer configured as a multiple quantum well (MQW) configured to emit light, and a second-type confinement layer having a roughened surface. In a first embodiment, the roughened surface includes a pattern of holes with a depth (d) in a major surface thereof surrounded by a pattern of protuberances with a height (h) on the major surface. In a second embodiment, the roughened surface includes a pattern of primary protuberances surrounded by a pattern of secondary protuberances.

摘要： A single light emitting diode (LED) structure includes an array of spaced discrete light emitting zones separated by isolation areas. Each emitting zone includes an epitaxial structure configured to emit an emitting light having a particular wavelength over an effective emission area. In addition, the effective emission area for each emitting zone can be geometrically defined and electrically configured to provide a desired light intensity. For example, each effective emission area can have a selected size and spacing depending on the application and light intensity requirements. Each emitting zone also includes a wavelength conversion member on its effective emission area configured to convert an emitting wavelength of the emitting light to a different color. The single (LED) structure can include multiple colors at different zones to produce a desired spectra or design. The single (LED) structure can also include a substrate for supporting the array, and the substrate can include one or more light shielding holes located between each emitting zone.
