    Abstract: High-performance light-emitting diode together with apparatus and method embodiments thereto are disclosed. The light emitting diode devices emit at a wavelength of 390 nm to 470 nm or at a wavelength of 405 nm to 430 nm. Light emitting diode devices are characterized by having a geometric relationship (e.g., aspect ratio) between a lateral dimension of the device and a vertical dimension of the device such that the geometric aspect ratio forms a volumetric light emitting diode that delivers a substantially flat current density across the device (e.g., as measured across a lateral dimension of the active region). The light emitting diode devices are characterized by having a current density in the active region of greater than about 175 Amps/cm2.

    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.

    Abstract translation: 公开了在LED灯中使用远程蓝色荧光体的发光器件和技术。 通过配置第一多个n个辐射源以发射以第一波长为特征的辐射，第一波长基本上为紫，并且配置第二多个m个辐射源以发射以第二波长为特征的辐射，形成LED灯， 第二波长也基本上是紫色的。 随着来自辐射源的光与各种波长转换材料（例如，红色发光材料的沉积物，黄色/绿色发光材料的沉积物等）相互作用，发出美学令人愉快的白光，包括发射蓝光的远程波长转换 层，被配置为吸收由第一多个辐射源发射的辐射的至少一部分。 远程波长转换层发射约420nm至约520nm的波长。
