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 &#x3bb;, so as to emit a light with a wavelength &#x3bb;. 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 &#x3bb;while the wavelength converting materials are irradiated by the light with &#x3bb;. Therefore, the brightness of a light emitting diode with the wavelength converting material is enhanced.

Light emitting diode and wavelength converting material

The present invention discloses a surface mount type light-emitting diode package device and a light-emitting element package device. In the device, the encapsulation layer comprises an encapsulation material and at least one material having a refraction index different from the encapsulation material distributed therein. The distribution of the material having a refraction index different from the encapsulation material is in a way such that the refraction index of the encapsulation layer is gradually reduced from the bottom portion upward to the top portion or the inner portion outward to the outer portion of the encapsulation layer. Accordingly, a difference between the refraction indexes of two adjoining media can be reduced to eliminate a total reflection and the Fresnel loss and enhance light extraction efficiency.

Surface mount type light-emitting element package device with high extraction efficiency due to gradually varying index of refraction and anti-reflective top layer

A light emitting diode includes two lead-frames, one or a plurality of light emitting chip, a casing, and a packaging colloid; the casing comprised of two pairs of a first and a second side units to surround a compartment; the first side unit being higher than the second side unit; the packaging colloid being received in the compartment; and the packaging colloid protruding from the casing to indicate a convex so to change angle of incidence of the light after leaving the packaging colloid and to improve light use efficiency and light emitting angle.
