Publication number: 20230411565Abstract: 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.Type: ApplicationFiled: August 9, 2023Publication date: December 21, 2023Applicant: SemiLEDs Optoelectronics Co., Ltd.Inventors: Trung Tri Doan, David Trung Doan
