Abstract

The present invention concerns a LED (L) lighting device (D) with integrated heatising (2), comprising: a printed circuit (C) of the PCB ( Printed Circuit Board) or MCPCB (Metal Core Printed Circuit Board) type, arranged for electrically and mechanically supporting a LED (L) matrix, forming the light source of said device (D); a heatsink (2) that may be associated in construction to said printed circuit (C), comprising a plurality of cooling fins (3, 8, 13, 14), characterized in that said cooling fins (3, 8, 13, 14) are arranged for being placed into direct contact with said LEDs (L) and each single cooling fin (3, 8, 13, 14) is arranged for dissipating only the heat produced by the specific LEDs (L) applied thereon. Heatsink (2) comprises cooling fins (3) with a cylindrical shape, (8) with lamellar structure or with prismatic shape with square bases (13) or rectangular bases (14) or with other regular shape, provided with ends (4) arranged for allowing the application of LEDs (L) and made out of high thermally conductive metals or out of composite alloys.
