Abstract: A method for assembling at least one lighting element (22) onto a substrate (40) is disclosed. The method comprises: pre-assembling at least one lighting element (22) onto a temporary carrier (10) that is or comprises a tape; pre-assembling at least one reference element (30) having an equal or greater thickness as the at least one lighting element onto the temporary carrier; aligning the p re-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. Substrate (40) is also disclosed, the substrate comprising: at least one lighting element (22), wherein the at least one lighting element is assembled onto the substrate, in particular by a method according to the above aspect. Use of the above method for assembling at least one lighting element (22) is also disclosed.

Abstract: 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.

Abstract: An LED array assembly may include a hybridized device and a flexible PCB. The hybridized device may include a micro-LED array mounted on a driver IC. The driver IC may include driver IC contact pads on a top surface of the driver IC. The flexible PCB may have a bottom surface, first contact pads on the bottom surface, second contact pads on the bottom surface, and contact bridges. Each of the contact bridges extends from one of the first contact pads to one of the second contact pads. Each of the driver IC contact pads is bonded to a corresponding one of the first contact pads of the flexible PCB.

Abstract: A lighting device and a method of manufacturing a lighting device (10) are described. A flat carrier (14) has front and rear surfaces (16, 18) facing in opposed front and rear directions. The carrier (14) comprises a cutout (40). A carrier-side electrical contact portion (26) is provided on the rear surface (18). A mounting element (30) comprises an LED element (12) and a mount-side electrical contact portion (36) electrically connected to the LED element (12). The mounting element (30) is arranged on the rear surface (18) such that an electrical contact is formed between the carrier-side and a mount-side electrical contact portions (26, 36), and such that the LED element (12) is arranged on or within the cutout (40) to emit light into the front direction. A heat sink element is positioned to the rear of the mounting element in thermal contact.
