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 (A); 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 , 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 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 , 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 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 . <EOS>
