Abstract
Embodiments of the invention include a semiconductor light emitting device, a first wavelength converting member disposed on a top surface of the semiconductor light emitting device, and a second wavelength converting member disposed on a side surface of the semiconductor light emitting device. The first and second wavelength converting members include different wavelength converting materials.
Claims22
A structure comprising:
- a semiconductor light emitting device;
- a first wavelength converting member disposed on a top light-emitting surface of the semiconductor light emitting device, the first wavelength converting member comprising a first wavelength converting material and is no wider than the top light-emitting surface;
- and
- a second wavelength converting member disposed on a side surface of the semiconductor light emitting device, the second wavelength converting member comprising a second wavelength converting material that is not over the top light-emitting surface, the first and second wavelength converting materials being different wavelength converting materials.
