Multi color active regions for white light emitting diode |
摘要 |
A light emitting diode device has a gallium and nitrogen containing substrate with a surface region with an epitaxial layer overlying the surface region. Preferably the device includes a first active region overlying the surface and configured to emit first electromagnetic radiation having a wavelength ranging from about 405 nm to 490 nm; a second active region overlying the surface and configured to emit second electromagnetic radiation having a wavelength ranging from about 491 nm to about 590 nm; and a third region overlying the surface region and configured to emit third electromagnetic radiation having a wavelength ranging from about 591 nm to about 700 nm. A p-type epitaxial layer covers the first, second, and third active regions.
