Abstract

In an embodiment a LED chip insert for a printed circuit board includes a lead frame in which a number of electrically conductive strings with respective ends are formed by punching, the strings having support surfaces which are configured for mounting on the printed circuit board and which form a common plane, wherein the lead frame has a region formed as a recess with respect to the ends, an injection molded frame including an electrically insulating material and annularly surrounding a surface of the lead frame exposed within the region formed as the recess facing the ends of the strings, and thereby effecting an overall trough-like structure; and at least one LED chip which is placed in the region formed as the recess and has a first electrical contact terminal and a second electrical contact terminal, the first electrical contact terminal being electrically conductively connected to a first one of the strings and the second electrical contact terminal being electrically conductively connected to a second one of the strings.
