  • Publication number: 20150155446
    Abstract: A method of manufacturing optoelectronic components includes spraying a fluorescent layer of an optoelectronic component onto a substrate, the substance or the substance mixture of the fluorescent layer including an electric charge when sprayed on, and wherein the electrically charged substance or the at least partially electrically charged substance mixture includes a larger electric potential when the fluorescent layer is sprayed on than at least one area of the substrate; and locally adjusting the thickness of the fluorescent layer of the sprayed-on fluorescent substance when spraying on the fluorescent layer onto the substrate by an electric potential gradient.

  • Publication number: 20150122785
    Abstract: A process of producing a component includes providing a substrate having an electrically conductive surface in the form of an electrically conductive layer; subdividing the layer with the aid of a laser process into a first electrically autonomous region and a second electrically autonomous region, wherein an electrically insulating region is formed in the electrically conductive layer to electrically separate the electrically autonomous regions; forming an electrical potential difference between the first electrically autonomous region and the second electrically autonomous region; and applying an electrically charged substance or an electrically charged substance mixture onto the first electrically autonomous region and/or the second electrically autonomous region, wherein the electrically autonomous region and/or an amount of the applied electrically charged substance or of the electrically charged substance mixture are adjusted by the electrical potential difference.

  • Publication number: 20140313728
    Abstract: An arrangement for generating light comprising a light emitting diode, comprising a conversion element, is proposed, wherein the conversion element is arranged above the light emitting diode and is provided for at least partly changing the wavelength of the electromagnetic radiation emitted by the light emitting diode, wherein the conversion element is designed in such a way that the light impinging on the conversion element from outside in a first color range is reflected, wherein the conversion element is surrounded by an edge region, wherein the edge region is designed in such a way that light impinging on the edge region in a second color range is reflected, wherein the second color range at least partly has a color range complementary to the first color range.
