A lighting unit includes a board, which supports a lamp and an electronic circuit for activating the lamp. The lamp includes one or more LEDs. The lighting unit further includes a decorative layer, which is applied directly to a surface of the board.

Lighting unit

The invention relates to a method for producing a coil integrated in a substrate or applied to a substrate, wherein the coil has first winding portions, which each have first ends and second ends, and wherein the coil has second winding portions and third winding portions, wherein each two of the first ends are electrically interconnected by the second winding portions and two corresponding second ends of the first winding portions are electrically interconnected by the third winding portions, such that coil windings of the coil are formed hereby, wherein at least the first winding portions are applied by means of a 3D printing method, wherein this is aerosol jet or inkjet printing, for example.

Method for producing a coil and electronic device

The subject matter of the invention relates to a method of producing a coil integrated in a substrate, using the following steps: creating the cavity in a substrate, said cavity having an open end which interrupts a surface of the substrate, introducing a paste containing ferromagnetic particles into the cavity so as to produce a coil core, closing the cavity by applying a cover layer so as to bridge the interruption in the surface of the substrate, introducing first winding portions of the coil which are vertical with respect to the surface, with a plurality or all of the first winding portions passing through the coil core contained inside the cavity, and applying second winding portions of the coil onto the surfaces of the substrate, with the second winding portions contacting the first winding portions so as to create the windings of the coil.

Method for producing a coil integrated in a substrate or applied to a substrate, and electronic device

The invention relates to a method for producing an optical module, comprising the following steps: a) providing a chip having an optical element integrated in the chip, wherein the optical element bas a first electrode and a second electrode, and wherein the chip has a first connection contact for the first electrode and a second connection contact for the second electrode, such that an operating voltage for the optical element can be applied between the first connection contact and the second connection contact, and wherein the chip has an optically active side, which is designed to emit and/or to receive radiation; b) connecting the chip to a film, such that the film completely covers the optically active side of the chip, wherein the film is a film made from acrylate, polyarylate, or polyurethane, wherein the film, at least in the region located above the optically active side, is transparent to radiation which. when operating voltage is applied, can be emitted or received by the optical element; c) contacting the first connection contact of the chip by means of a conducting track arranged on the film and contacting the second connection contact by means of an additional conducting track.
