    Abstract: In one embodiment, the transparent growth substrate of an LED die is formed to have light scattering areas, such as voids formed by a laser. In another embodiment, the growth substrate is removed and replaced by another substrate that is formed with light scattering areas. In one embodiment, the light scattering areas are formed over the light absorbing areas of the LED die, to reduce the amount of incident light on those absorbing areas, and over the sides of the substrate to reduce light guiding. The replacement substrate may be formed to include reflective particles in selected areas. A 3D structure may be formed by stacking substrate layers containing the reflective areas. The substrate may be a transparent substrate or a phosphor tile that is affixed to the top of the LED.

    Abstract: A phosphor converted Light Emitting Diode (LED), a lamp and a luminaire are provided. The phosphor converted LED comprises a LED, a first luminescent material, a second luminescent material and a third luminescent material. The LED emits a first spectral distribution having a first peak wavelength in the blue spectral range. The first luminescent material absorbs a portion of the light of the first spectral distribution and converts at least a portion of the absorbed light towards light of a second spectral distribution. The second spectral distribution has a second peak wavelength in the green spectral range. The second luminescent material absorbs absorbing a portion of the light of the first spectral distribution and/or a portion of the second spectral distribution. The second luminescent material converts at least a portion of the absorbed light towards lights of a third spectral distribution. The third spectral distribution has a third spectral width and has a third peak wavelength. The third luminescent material absorbs a portion of the light of at least one of the first spectral distribution, second spectral distribution, and the third spectral distribution. The third luminescent material converts at least a portion of the absorbed light towards light of a fourth spectral distribution. The fourth spectral distribution has a fourth spectral width and has a fourth peak wavelength. The third peak wavelength and the fourth peak wavelength are in the orange/red spectral range. The third peak wavelength is smaller than the fourth peak wavelength and the third spectral width is larger than the fourth spectral width.
