An LED illumination module is disclosed, wherein a series of LED elements (1) is arranged over a substrate (16) on a secondary cooling element (2). The secondary cooling element (2) can consist of a first material layer (16, 17) made of copper and a second material layer (18) made of aluminium. With these kind of material combinations, a good lateral distribution of heat is produced on the basis of phonic refraction, as result of which the flow of heat is improved and temperature gradients are reduced. Alternatively or additionally, the secondary cooling element (2) can be fitted with heat pipes. The LED elements (1) are electrically contacted via a power feed element (21) which is spaced from the substrate (16).
