Document Type and Number:
Japanese Patent JP2010510650
Kind Code:
A
Abstract:
A ceramic body comprising a wavelength converting material is disposed in the path of light emitted by the light emitting region of a semiconductor structure comprising a light emitting region disposed between an n-type region and a p-type region. A layer of transparent material is also disposed in the path of light emitted by the light emitting region. The transparent material may connect the ceramic body to the semiconductor structure. Particles configured to scatter light emitted by the light emitting region are disposed in the layer of adhesive material. In some embodiments the particles are phosphor; in some embodiments the particles are not a wavelength-converting material.
