Abstract:
1. A light emitting diode arrangement, comprising: a flexible circuit board comprising electrical conductor tracks and a thermally conductive layer; a plurality of sections, wherein each section has a single high power light-emitting diode, an associated pair of electrical contact areas, an associated pair of electrical connection locations, a plurality of first electrical conductor tracks, and a plurality of second electrical conductor tracks; a plurality of thermally conductive layers separated from each other; and a plurality of high power light-emitting diodes, wherein the electrical contact areas and the electrical connection locations of a same section are electrically connected to one another by the first electrical conductor tracks, and wherein the electrical connection locations of neighboring sections are electrically connected to one another by the second electrical conductor tracks; and wherein each high power light emitting diode is mounted onto said flexible circuit board and in thermal contact with the thermally conductive layer, the high power light emitting diode including a thermal connection part in thermal contact with the thermally conductive layer; wherein the thermally conductive layer and the electrical conductor tracks are positioned in a same plane of the flexible circuit board; and wherein the thermally conductive layer occupies at least 60% of an area of said same plane.
