A rotating lighting module designed to equip a lighting device for vehicles, comprising at least one first LED light source, at least one first reflector and at least one first actuator to rotate the first reflector relative to the first LED light source around a first axis; wherein a framed support holds rigid in a fixed position said first LED light source and bears in idling manner said first reflector; wherein i)- the at least one first LED light source is operatively associated with the framed support in such a manner to transfer thereto by heat conduction at least a major part of a thermal flow generated in operation by the first LED light source; and wherein, in combination, ii)- the framed support is made entirely of a heat conductive metal or metal alloy and is designed to behave as a thermal dissipator; characterized in that iii)- the framed support is formed by a side by side junction, via removable transversal fixing elements, of two specular symmetric structural elements (33,34), each comprising a first end section and a middle section having C-shaped solid cross-sections and a second end section, opposite the first end section and shaped like an half shell; iv)- the first end sections of the two structural elements, when joined, forming a first section of the framed support, closer to the first LED light source and having a double T cross-section formed by the joined two C-shaped cross sections of the two structural elements (33, 34) arranged facing opposite to each other, while the middle sections of the two structural elements, when joined, forming a middle section of the framed support, also having a double T cross-section formed by the joined two C-shaped cross sections of the two structural elements arranged facing opposite to each other; v)- the second end sections of the two structural elements, when joined, forming a second section of the framed support, farthest away from the first LED light source and having a box-like shape in order to idly receive the said first reflector. i)- the at least one first LED light source is operatively associated with the framed support in such a manner to transfer thereto by heat conduction at least a major part of a thermal flow generated in operation by the first LED light source; and wherein, in combination, ii)- the framed support is made entirely of a heat conductive metal or metal alloy and is designed to behave as a thermal dissipator; characterized in that iii)- the framed support is formed by a side by side junction, via removable transversal fixing elements, of two specular symmetric structural elements (33,34), each comprising a first end section and a middle section having C-shaped solid cross-sections and a second end section, opposite the first end section and shaped like an half shell; iv)- the first end sections of the two structural elements, when joined, forming a first section of the framed support, closer to the first LED light source and having a double T cross-section formed by the joined two C-shaped cross sections of the two structural elements (33, 34) arranged facing opposite to each other, while the middle sections of the two structural elements, when joined, forming a middle section of the framed support, also having a double T cross-section formed by the joined two C-shaped cross sections of the two structural elements arranged facing opposite to each other; v)- the second end sections of the two structural elements, when joined, forming a second section of the framed support, farthest away from the first LED light source and having a box-like shape in order to idly receive the said first reflector.
