  • Publication number: 20200251633
    Abstract: Aspects include features for improving the reliability of a reflective base structure for light emitting diodes (LED) chip-on-board (COB) array products. The reflective base structure reduces reflective material of a reflective layer (e.g., silver) from migrating into adjacent layers. In one configuration used to reduce the migration of reflective material, a reflective base for a light-emitting diode (LED) may comprise a substrate, a reflective layer, and a diffusion barrier layer between the substrate and the reflective layer. In another configuration used to reduce the migration of reflective material, a reflective base for an LED comprising: a substrate, a reflective layer; and a planarizing layer between the substrate and the reflective layer, a thickness of the planarizing layer between the substrate and the reflective layer being less than 70 nm.

  • Patent number: 9502620
    Abstract: A low-cost device for packaging LED dies provides superior reflectivity and thermal conductivity without covering entire surfaces of an LED luminaire with an expensive reflective aluminum substrate. The LED packaging device includes a highly reflective substrate disposed in a hole in a printed circuit board. The substrate has a reflectivity greater than 97% and includes an insulating layer and a reflective layer disposed above a thicker aluminum layer. An LED die is disposed on the top surface of the substrate. The PCB has a layer of glass fiber in resin and a metal layer. The lower surface of the PCB and the bottom surface of the substrate are substantially coplanar. The metal layer of the PCB is electrically coupled to the LED die only through bond wires. Electronic circuitry is disposed on the upper surface of the PCB and is used to control light emitted from the LED die.

  • Patent number: 8710361
    Abstract: Volume compensation in photovoltaic device is provided. The photovoltaic device has an outer transparent casing and a substrate that, together, define an inner volume. At least one solar cell is on the substrate. A filler layer seals the at least one solar cell within the inner volume. A container within the inner volume has an opening in fluid communication with the filler layer. A diaphragm is affixed to the opening thereby sealing the interior of the container from the filler layer. The diaphragm is configured to decrease the volume within the container when the filler layer thermally expands and to increase the volume within the container when the filler layer thermally contracts. In some instances, the substrate is hollowed and the container is formed within this hollow. The container can have multiple openings, each sealed with a diaphragm. There can be multiple containers within the photovoltaic device.

  • Patent number: 8597549
    Abstract: Disclosed are highly efficient multiphoton absorbing compounds and methods of their use. The compounds generally include a bridge of pi-conjugated bonds connecting electron donating groups or electron accepting groups. The bridge may be substituted with a variety of substituents as well. Solubility, lipophilicity, absorption maxima and other characteristics of the compounds may be tailored by changing the electron donating groups or electron accepting groups, the substituents attached to or the length of the pi-conjugated bridge. Numerous photophysical and photochemical methods are enabled by converting these compounds to electronically excited states upon simultaneous absorption of at least two photons of radiation. The compounds have large two-photon or higher-order absorptivities such that upon absorption, one or more Lewis acidic species, Lewis basic species, radical species or ionic species are formed.
