Abstract
Light emitting structures are disclosed that can include a semiconductor light emitting diode (LED) that includes a p-n junction active layer. A first layer can include a binder material having a thickness that is less than about 1000 μm, wherein the first layer is directly on the LED. A second layer can include phosphor particles, where the second layer can have a thickness that is less than about 1000 μm and can be directly on the first layer so that the first layer is between the LED and the second layer.
