  • Patent number: 7718088
    Abstract: A wavelength converting material including a wavelength converting activator and a scatter is provided. The wavelength converting activator is suitable for being activated by a light with a wavelength ?1, so as to emit a light with a wavelength ?2. The scatter is disposed on the wavelength converting activator. The scatter is suitable for scattering a first light and a second light irradiated to a surface thereof. As a result of that the scatters on the wavelength converting activators increases the gap of two wavelength converting activators adjacent to each other, the wavelength converting activators could be sufficiently activated for emitting a light with wavelength ?2 while the wavelength converting materials are irradiated by the light with ?1. Therefore, the brightness of a light emitting diode with the wavelength converting material is enhanced.
