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.
Claims16
A light emitting structure, comprising:
- a semiconductor light emitting diode (LED) comprising a p-n junction active layer;
- a first layer comprising binder material having a thickness less than about 1000 μm directly on the LED;
- a second layer comprising phosphor particles and having a thickness less than about 1000 μm, the second layer directly on the first layer so that the first layer is between the LED and the second layer;
- and
- a third layer on the second layer, the third layer comprising diffuser particles.
