摘要：
The present invention is related to a lighting device (100, 200, 300) and to a method for manufacturing such lighting device (100, 200, 300). A template (102) is provided having cavities (104) distributed across the template (102). The cavities (104) define mounting positions for a plurality of light source packages (110) each comprising a light source (112). The shape of the cavities matches the shape of the light source packages (110) such that the light source packages (110) have a limited number of possible mounting configurations in the cavities (104). Subsequently electrical conductors (122) are applied on a top surface of the template (102) for contacting electrodes of the light source packages (110). The light source packages (110, 208, 300) or the plurality of cavities comprise a reflective bottom layer (132, 220) and a light emitting surface of the light source (112, 210) faces the reflective bottom layer (132, 220).
技术问题语段：
The technical problem addressed in this patent text is how to manufacture personalized light-emitting devices with complex shapes while keeping the cost down per manufactured unit and meeting the customer demand.
技术功效语段：
The present invention is based on the realization that a nearly arbitrarily shaped lighting device can be manufactured by a method comprising forming electrical connections after the light source packages have been placed. An improved, simple manufacturing method and lighting device can be realized by using a template comprising cavities such that predefined positions for the light source packages are made. The shape of the light source packages matches the shape of the cavities, allowing for proper fitting of the light source packages. A cost effective manufacturing method for personalized lighting devices is realized. The top layer covers the template and the electrical conductors, providing scratch protection, a humidity barrier, and optical functionality such as creating diffuse light, converting light color, and mixing colors. The top layer may be fabricated using a 3D printing method.
