    摘要： A light emitting device in which a primary light generator, such as a light emitting diode (LED) or laser diode, is operable to emit a primary light that is received by a body of wavelength converting material. A portion of the primary light is absorbed by the body of wavelength converting material and is emitted as secondary light. The wavelength converting material contains phosphor nano-particles and larger phosphor particles. The phosphor nano-particles prevent transmission of primary light while the larger phosphor particles provide efficient light conversion.

    摘要： A method for packaging a light emitting device, in which a primary light generator, such as a light emitting diode semiconductor die or laser diode, is attached to a lead frame and covered with a body of phosphor material so as to form a predetermined thickness of phosphor material covering the primary light generator. The body of phosphor material may be contained in a substantially transparent container or preformed, compressed disc. The resulting light emitting device has a primary light generator covered by phosphor material that is constrained to have a predetermined thickness.

    摘要： A device and method for producing output light having a wavelength spectrum in the visible wavelength range and the infrared wavelength range uses a fluorescent material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to produce the output light. The light source may be configured to generate light having a peak wavelength in an ultraviolet-and-visible wavelength range. The fluorescent material may include any combination of red, green, blue and yellow phosphors.

    摘要： A light source having a light emitting semiconductor device on a die and a light conversion layer is disclosed. The die emits light of a first wavelength. The light conversion layer overlies the die and includes a first soluble fluorescent dye and a second fluorescent dye in a solid clear plastic carrier. The first and second florescent dyes convert the light entering the conversion layer to light of second and third wavelengths, respectively. At least one of the first and second dyes is excited by light of the first wavelength. In one embodiment, the second and third wavelengths are present in a ratio of intensities such that the light leaving the light conversion layer is perceived as white light by a human observer. The light conversion layer may be divided into sub-layers that include the individual dyes.
