Beschreibung
Zusammenfassung:	A folded light engine comprising an array of LEDs mounted on a strip substrate, wherein the strip substrate comprises a central portion provided with a first set of through-holes, a first peripheral portion provided with an electrically conducting track connecting a first group of LEDs and a second set of through holes, and a second peripheral portion provided with an electrically conducting track connecting a second group of LEDs. The first peripheral portion is folded over the central portion, so that the LEDs thereon coincide with through-holes in the central portion, and the second peripheral portion is folded over the first peripheral portion, so that each LEDs thereon coincide with a combined through-hole formed by through-holes in the central portion and in the first peripheral portion. An elongated light engine can be cost efficiently manufactured in a relatively simple processes, including single-sided circuit patterning and LED mounting.
