The invention refers to a method for assembling at least one lighting element onto a substrate, the method comprising: pre-assembling at least one lighting element onto a temporary carrier; pre-assembling at least one reference element onto the temporary carrier; aligning the pre-assembled temporary carrier onto the substrate based, at least in part, on the at least one reference element of the temporary carrier; and mounting the at least one lighting element onto the substrate. The invention further relates to substrate comprising: at least one lighting element, wherein the at least one lighting element is assembled onto the substrate, in particular by a method according to the first aspect of the present invention, and to a use of a method for assembling at least one lighting element onto a substrate.

Lighting element alignment

A composite array has two two-dimensional arrays on a substrate each having two rows of LEDs. The LEDs in each array have the same orientation as all other LEDs in that array. First electrical traces sequentially couple LEDs in the first string and the second string by beginning at opposite corners of the composite array and alternating between rows of each of the first and second arrays. A second electrical trace couples ends of the first and second strings across rows of the composite array. Third electrical traces route outside the composite array and are coupled, respectively, to a beginning of the first string for the row of the composite array containing the beginning of the first string, a beginning of the second string for the other row, the end of the first LED string for the other row, and electrodes of LEDs in the other row.

The invention describes an LED lighting arrangement comprising a single-layer carrier comprising a mounting surface, a metal core, and a dielectric layer between the mounting surface and the metal core; at least one LED string comprising a plurality of series-connected LED die packages mounted on the mounting surface, wherein the LED die packages of a string are arranged in a two-dimensional array comprising at least two rows; and at least one micro-via extending through the dielectric layer of the single-layer carrier and arranged to electrically connect the final cathode of an LED string to the metal core of the single-layer carrier. The invention further describes a lighting unit; and a method of manufacturing an LED lighting arrangement.

LED lighting arrangement

A lighting device, a method of manufacturing a lighting device and a support are described. A support includes a layered structure of alternating conductors and insulating layers. The layered structure includes a mounting section and a body section adjacent the mounting section. The mounting section includes at least one mounting face that has an arrangement direction and at least three alternating contact sections along the arrangement direction. Each contact section is electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers. The body section has a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction.

Support for light-emitting elements and lighting device

The invention refers to a carrier for at least one lighting module, the carrier comprising: at least one mounting portion for receiving the at least one lighting module, wherein the carrier has a triangular cross section at least in sections with the at least one mounting portion being arranged on an edge of the triangular cross section; and a heat sink body portion arranged adjacent to the at least one mounting portion, wherein the heat sink body portion protrudes sidewards from the at least one mounting portion. The invention further relates to a lighting device and a method for producing such lighting device.

Carrier for lighting modules and lighting device

A lighting device and a method of manufacturing a lighting device are described. A lighting device includes a flat carrier that has a front surface and a rear surface opposite the front surface. The flat carrier includes a cutout and multiple carrier-side electrical contacts on the rear surface. A mounting element is provided on the rear surface of the flat carrier and includes multiple mount-side electrical contacts electrically coupled to the multiple carrier-side electrical contacts and an elevated portion projecting into the cutout. Multiple LED elements are provided on the elevated portion of the mounting element and electrically coupled to the mounting element on the same side as the multiple mount-side side electrical contacts. A heat sink element is thermally coupled to the mounting element on a side of said mounting element opposite the flat carrier.
