    摘要： A Group III nitride based light emitting diode includes a p-type Group III nitride based semiconductor layer, an n-type Group III nitride based semiconductor layer that forms a P-N junction with the p-type Group III nitride based semiconductor layer, and a Group III nitride based active region on the n-type Group III nitride based semiconductor layer. The active region includes a plurality of sequentially stacked Group III nitride based wells including respective well layers. The plurality of well layers includes a first well layer having a first thickness and a second well layer having a second thickness. The second well layer is between the P-N junction and the first well layer, and the second thickness is greater than the first thickness.

    摘要： Light emitting devices include an active region of semiconductor material and a first contact on the active region. The first contact is configured such that photons emitted by the active region pass through the first contact. A photon absorbing wire bond pad is provided on the first contact. The wire bond pad has an area less than the area of the first contact. A reflective structure is disposed between the first contact and the wire bond pad such that the reflective structure has substantially the same area as the wire bond pad. A second contact is provided opposite the active region from the first contact. The reflective structure may be disposed only between the first contact and the wire bond pad. Methods of fabricating such devices are also provided.

    摘要： A light emitting device includes an LED and a layer of luminophoric particles, such as phosphor, that are non-homogeneous in size as a function of distance away from the LED. For example, a first layer of relatively large size phosphor particles may be provided between a second layer of relatively small size phosphor particles and the LED. The large particles can provide high brightness and the small particles can reduce angular color temperature variation in emitted light.
