  • Publication number: 20080061310
    Abstract: A light emitting diode device includes a multi-layer stack of materials including a p-layer, a n-layer, and a light generating region for emission of light in a primary emission direction towards one of the p- and n-layers; a substantially transparent layer located at or adjacent said one of the p- and n-layers, having a first surface facing said one of the p- and n-layers and an opposed second surface; and a reflective surface formed at or adjacent the second surface of the transparent layer for directing at least a portion of the emitted light in a direction away from the primary emission direction so as to enhance light emission from a side of the light emitting diode device.

  • Publication number: 20080061306
    Abstract: A semiconductor light emitting device includes a multi-layer stack of materials including a layer of p-doped material, a layer of n-doped material, and a light generating region therebetween; a first thermal conduction path between the light generating region and the exterior of the device; and a second thermal conduction path having a higher thermal conductivity than that of the first thermal conduction path. The second thermal conduction path is for providing enhanced thermal dissipation from the light generating region to the exterior.

  • Publication number: 20080061304
    Abstract: A semiconductor light emitting device for emission of light having a predetermined bandwidth in a primary direction of emission includes a light generating region for the generation of light; and a 1-dimensional photonic crystal structure having a photonic bandgap covering at least a segment of said bandwidth. The 1-dimensional photonic crystal structure is located such that upon incident of light from the light generating region, light having a wavelength within the bandgap of the 1-dimensional photonic crystal structure is reflected in the primary direction of emission.

  • Patent number: 7105909
    Abstract: A structural configuration and manufacture method is applied to manufacture electronic circuits on a ceramic substrate including capacitor and inductors for filters. The electronic circuits have strong bonding to securely adhere to the SOG-coated substrate when the SOG is cured at an elevated temperature supplemented with high nitrogen flow during the curing process. The SOG coated ceramic substrate shows excellent layer compatibilities during temperature variations because reduced differences of thermal coefficients between different layers.
