    摘要: A light emitting device or array comprising a submount having a top surface, a bottom surface and a plurality of edges, with input and output terminals disposed on the top surface. A plurality of attach pads and traces are also disposed on the top surface and electrically connected between the input and output terminals. A plurality of LEDs are also included, each of which is mounted to one of the attach pads. The attach pads cover more of the top surface than the LEDs and spread heat from the LEDs to the top surface of the submount. A plurality of lenses are also included each of which is molded over a respective one of the attach pads and covers the LED mounted to the particular attach pad. The arrays are shaped and arranged so that they can be easily attached to similar arrays in a tiling fashion, with the desired number of arrays included to meet the desired lighting requirements. Methods for fabricating the arrays from a single submount or submounts panel are also disclosed.

    摘要: A white light emitting lamp is disclosed comprising a solid state ultra violet (UV) emitter that emits light in the UV wavelength spectrum. A conversion material is arranged to absorb at least some of the light emitting from the UV emitter and re-emit light at one or more different wavelengths of light. One or more complimentary solid state emitters are included that emit at different wavelengths of light than the UV emitter and the conversion material. The lamp emits a white light combination of light emitted from the complimentary emitters and from the conversion material, with the white light having high efficacy and good color rendering. Other embodiments of white light emitting lamp according to the present invention comprises a solid state laser instead of a UV emitter. A high flux white emitting lamp embodiment according to the invention comprises a large area light emitting diode (LED) that emits light at a first wavelength spectrum and includes a conversion material. A plurality of complimentary solid state emitters surround the large area LED, with each emitter emitting light in a spectrum different from the large area LED and conversion material such that the lamp emits a balanced white light. Scattering particles can be included in each of the embodiments to scatter the light from the emitters, conversion material and complimentary emitters to provide a more uniform emission.

    摘要: A method and apparatus for forming a porous layer on the surface of a semiconductor material wherein an electrolyte is provided and is placed in contact with one or more surfaces of a layer of semiconductor material. The electrolyte is heated and a bias is introduced across said electrolyte and the semiconductor material causing a current to flow between the electrolyte and the semiconductor material. The current forms a porous layer on the one or more surfaces of the semiconductor material in contact with the electrolyte. The semiconductor material with its porous layer can serve as a substrate for a light emitter. A semiconductor emission region can be formed on the substrate. The emission region is capable of emitting light omnidirectionally in response to a bias, with the porous layer enhancing extraction of the emitting region light passing through the substrate.
