Abstract (en)

[origin: WO2021148484A1] An LED chip insert for a circuit board comprises: a leadframe, in which punching is used to form a number of electrically conductive strands having respective ends having bearing surfaces that are designed for attachment to a circuit board and that form a common plane; wherein the leadframe has a region in the form of a depression in relation to the ends, an injection-moulded frame that is formed from an electrically insulating material and annularly surrounds a surface of the leadframe, which surface is exposed within the region of the depression and faces the ends of the strands, and consequently achieves a trough-shaped overall structure, at least one LED chip that is placed in the region in the form of a depression and has a first electrical contact connection and a second electrical contact connection, wherein the first electrical contact connection is electrically conductively connected to a first of the strands and the second electrical contact connection is electrically conductively connected to a second of the strands. The region of the leadframe in the form of a depression in relation to the ends may be inserted into a cutout in the circuit board such that the back faces thereof terminate flush with one another. In the lighting module, the back face of the depressed region of the circuit board may be in contact with an end cooling surface of a heat sink and dissipate heat there.
