  • Patent number: 12122985
    Abstract: The invention discloses cleaning compositions which employ a synergistic combination of an ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.

  • Patent number: 10886437
    Abstract: An inorganic coating may be applied to bond optically scattering particles or components. Optically scattering particles bonded via the inorganic coating may form a three dimensional film which can receive a light emission, convert, and emit the light emission with one or more changed properties. The inorganic coating may be deposited using a low-pressure deposition technique such as an atomic layer deposition (ALD) technique. Two or more components, such as an LED and a ceramic phosphor layer may be bonded together by depositing an inorganic coating using the ALD technique.

  • Patent number: 10290775
    Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.

  • Patent number: 10023796
    Abstract: An illumination system comprising a radiation source and a monolithic ceramic luminescence converter comprising a composite material of at least one luminescent compound, and at least one non-luminescent compound, wherein the material of the non-luminescent compound comprises silicon and nitrogen, is advantageously used, when the luminescent compound comprises an rare-earth metal-activated host compound also comprising silicon and nitrogen. Shared chemical characteristics of the luminescent compound and the non-luminescent material improve phase assemblage, thermal and optical behavior. The invention relates also to a composite monolithic ceramic luminescence converter.

  • Patent number: 9944849
    Abstract: The invention provides a light emitting diode device comprising a light emitting diode arranged on a substrate and a wavelength converting element. The wavelength converting element contains as a luminescent material a Mn4+-activated fluoride compound having a garnet-type crystal structure. The Mn4+-activated fluoride compound preferably answers the general formula {A3}[B2-x-yMnxMgy](Li3)F12-dOd, in which formula A stands for at least one element selected from the series consisting of Na+ and K+ and B stands for at least one element selected from the series consisting of Al3+, B3+, Sc3+, Fe3+, Cr3+, Ti4+ and In3+, and in which formula x ranges between 0.02 and 0.2, y ranges between 0.0 (and incl. 0.0) and 0.4 and d ranges between 0 (and incl. 0) and 1. Said compound is most preferably {Na3}[Al2-x-yMnxMgy](Li3)F12-dOd.

  • Patent number: 8957439
    Abstract: A light emission diode (LED) assembly, comprising a LED die (10), a phosphor layer (12), and a filter layer (14), wherein said filter layer (14) is developed in such a manner that light rays with a wavelength of about 400 nm to 500 nm, preferably of about 420 nm to 490 nm, emitted from the LED die (10) are at least partially reflected depending on their emission angle to the normal on the filter layer (14). With the inventive LED assembly it is possible to provide a LED assembly which solves the yellow ring problem without a reduction of the efficiency of the LED assembly.
