LED PACKAGE FOR UNIFORM COLOR EMISSION

摘要

Disclosed is a light emitting diode package (200) for one or more light emitting diodes mounted on a substrate (215). A frame (220) is disposed on at least a portion of the substrate and substantially surrounds, but does not contact, the light emitting diode (210). The frame is substantially transparent to light emitted from the light emitting diode and includes one or more first wavelength converting materials. The wavelength converting materials, which may be one or more phosphors, convert at least a portion of light emitted at the emission wavelength into different wavelength. A cover (230) covers the light emitting diode within the frame. The cover includes one or more second wavelength converting materials differing from the first one or more wavelength converting materials in wavelength converting material concentration or in converted light wavelength or in combinations of wavelength converting materials.
