    Abstract: LED packages are disclosed that are compact and efficiently emit light, and can comprise encapsulants with curved and planar surfaces. The packages can comprise a submount with a one or a plurality of LEDs, and in those with a plurality of LEDs each of the LEDs can emit the same or different wavelengths of light than the others. A blanket conversion material layer can be included on at least some of the LEDs and the submount. The encapsulant can be on the submount, over at least some of the LEDs, with each of the planar surfaces being vertical and aligned with one of the edges of the submount. The packages can also comprise reflective layers to minimize losses due to light absorption, which in turn can increase the overall package emission efficiency.

    Abstract: Light emitting devices include an LED that emits light having a dominant wavelength in the blue color range and a recipient luminophoric medium that is configured to down-convert at least some of the light emitted by the LED. In these devices, the recipient luminophoric medium may include at least a green phosphor that down-converts the radiation emitted by the LED to radiation having a peak wavelength that is between about 525 nanometers and about 545 nanometers, a yellow phosphor that down-converts the radiation emitted by the LED to radiation having a peak wavelength that is between about 550 nanometers and about 570 nanometers, and a red (Ca1-x-ySrxEu2+y)SiAlN3 phosphor. The red (Ca1-x-ySrxEu2+y)SiAlN3 phosphor may have a europium content of at least 0.025.

    Abstract: A light emitting device includes a p-type semiconductor layer, an n-type semiconductor layer and an active region between the p-type semiconductor layer and the n-type semiconductor layer. A bond pad is provided on one of the p-type semiconductor layer or the n-type semiconductor layer, opposite the active region, the bond pad being electrically connected to the one of the p-type semiconductor layer or the n-type semiconductor layer. A conductive finger extends from and is electrically connected to the bond pad. A reduced conductivity region is provided in the light emitting device that is aligned with the conductive finger. A reflector may also be provided between the bond pad and the reduced conductivity region. A reduced conductivity region may also be provided in the light emitting device that is not aligned with the bond pad.
