    Abstract: To increase the lattice constant of AlInGaP LED layers to greater than the lattice constant of GaAs for reduced temperature sensitivity, an engineered growth layer is formed over a substrate, where the growth layer has a lattice constant equal to or approximately equal to that of the desired AlInGaP layers. In one embodiment, a graded InGaAs or InGaP layer is grown over a GaAs substrate. The amount of indium is increased during growth of the layer such that the final lattice constant is equal to that of the desired AlInGaP active layer. In another embodiment, a very thin InGaP, InGaAs, or AlInGaP layer is grown on a GaAs substrate, where the InGaP, InGaAs, or AlInGaP layer is strained (compressed). The InGaP, InGaAs, or AlInGaP thin layer is then delaminated from the GaAs and relaxed, causing the lattice constant of the thin layer to increase to the lattice constant of the desired overlying AlInGaP LED layers. The LED layers are then grown over the thin InGaP, InGaAs, or AlInGaP layer.

Because the LEDs are directly mounted on the surface of the heat pipe apparatus, the heat generated by the lighting LEDs is effectively delivered to the atmosphere due to the reaction of latent heat phase transformation in the heat pipe apparatus. Moreover, the heat is delivered to the heat sinks at far sides for heat exchange so that improved heat dissipation and a space saving result are achieved.

  • Publication number: 20090085050
    Abstract: An island submount used for carrying at least one light-emitting element having at least one electrical contact. The island submount includes a substrate, at least one island structure having a top surface and an inclined surface, and a conductive layer. The island structure is located on the substrate and corresponds to the electrical contact. The conductive layer is formed on the surface of the island structure and at least covers the top surface, so as to be electrically connected with the electrical contact. The island submount is capable of enhancing the light extraction efficiency of the light-emitting element, and avoids the energy loss due to re-absorption when the light emerging from below the light-emitting element is reflected back to the light-emitting element.

  • Publication number: 20090078955
    Abstract: Disclosed is a semiconductor micro-emitter array for use in a full-color microdisplay. Each pixel includes three vertically-stacked red, green, and blue micro-emitters which minimizes pixel size. The microdisplay may be exclusively based on Group III-nitride semiconductors, with differing indium concentrations in three respective InGaN/GaN active regions for emitting the three RGB colors. Alternatively the microdisplay may be based on hybrid integration of InGaN based III-nitride semiconductors for blue and green emissions, and AlGaInP based (e.g., Group III-V) semiconductors for red emissions.

  • Publication number: 20090039369
    Abstract: A semiconductor light emitting apparatus can include a housing filled with a wavelength conversion material-containing resin material which seals a semiconductor light emitting device inside the recess of the housing. A transparent resin material can be charged on the wavelength conversion material-containing resin material, and can be configured to prevent the resin materials from being detached from each other or from other portions, such as a housing. Furthermore, such a semiconductor light emitting apparatus can emit light with less color unevenness. The housing can include a first recessed portion and a second recessed portion. The second recessed portion can have a larger diameter than the first recessed portion so as to form a stepped area at the boundary therebetween. The first recessed portion is filled with the wavelength conversion material-containing resin material as a first resin.
