Abstract: A light emitting device includes a LED having a light emitting first surface and a light emitting second surface that define a corner. A support layer is disposed to receive light emitted by the light emitting second surface and is disposed adjacent the corner. A luminophoric medium layer at least partially covers the light emitting first surface and the light emitting second surface where the luminophoric medium layer is at least partially supported by the support layer to prevent a narrowing of the luminophoric medium layer.

The light-altering material may be arranged on a lumiphoric material adjacent to the LED chip in various configurations. The LED package may include an encapsulant on the light-altering material and the lumiphoric material.

Abstract: Solid-state lighting devices including light-emitting diodes (LEDs), and more particularly binder materials for light-emitting devices are disclosed. A lumiphoric material for a light-emitting device may include lumiphoric particles embedded within a binder material. The lumiphoric material may be formed according to sol-gel chemistry techniques where a solution of binder precursors and lumiphoric particles is applied to a surface, dried to reduce liquid phase, and fired to form a hardened and dense lumiphoric material. The binder precursors may include metal oxide precursors that result in a metal oxide binder. In this manner, the lumiphoric material may have high thermal conductivity while also being adaptable for liquid-phase processing. In further embodiments, binder materials with or without lumiphoric particles may be utilized in place of conventional encapsulation materials for light-emitting devices.

Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and lens arrangements for packaged LED devices are disclosed. An LED package may include one or more LED chips on a submount with a lens positioned on the submount to form a cavity. The one or more LED chips may reside in the cavity without direct encapsulation materials that would otherwise contact the one or more LED chips and any corresponding wirebonds. In this manner, the one or more LED chips may be driven with higher drive currents while reducing degradation and mechanical strain effects related to differences in coefficients of thermal expansion with typical encapsulant materials. LED packages may also be configured with one or more apertures that allow air flow between an interior volume of a cavity and an ambient environment outside the LED package to promote heat dissipation at higher drive currents.

Abstract: The invention relates to a flavonoid delivery system comprising a co-precipitate of a hydrophobic flavonoid and a protein. The flavonoid delivery system comprises a high ratio of flavonoid to protein, allowing food products to be fortified with relatively large amounts of flavonoid without compromising the sensory properties of the food product.

Abstract: Process for producing a hydrogen-containing product and one or more liquid water products using catalytic steam-hydrocarbon reforming. In the process, a portion of the make-up water is heated by the reformate and another portion of the make-up water is heated by the combustion product gas prior to introducing the make-up water to a deaerator. Water in the combustion product gas is condensed to form a liquid water product. The process may be integrated with a thermal water desalination process.
