Abstract: A light emitting diode device has a bulk gallium and nitrogen containing substrate with an active region. The device has a lateral dimension and a thick vertical dimension such that the geometric aspect ratio forms a volumetric diode that delivers a nearly uniform current density across the range of the lateral dimension.

Abstract: Light emitting devices and techniques for using remote blue phosphors in LED lamps are disclosed. An LED lamp is formed by configuring a first plurality of n of radiation sources to emit radiation characterized by a first wavelength, the first wavelength being substantially violet, and configuring a second plurality of m of radiation sources to emit radiation characterized by a second wavelength, the second wavelength also being substantially violet. Aesthetically-pleasing white light is emitted as the light from the radiation sources interacts with various wavelength converting materials (e.g., deposits of red-emitting materials, deposits of yellow/green-emitting materials, etc.) including a blue-emitting remote wavelength converting layer configured to absorb at least a portion of the radiation emitted by the first plurality of radiation sources. The remote wavelength converting layer emits wavelengths ranging from about 420 nm to about 520 nm.
