Claim 2:
3. A luminaire head comprising:
a thermally conductive metal body comprising a plate-like portion, a tube portion, and at least one cooling fin,
said plate-like portion extending in a longitudinal direction L of the metal body and having a flat first surface and a second surface opposite said first surface, said tube portion extending in said longitudinal direction at said second surface,
said at least one cooling fin extending away from said second surface adjacent to the tube portion; and
at least one support substrate with a plurality of light emitting elements, said at least one support substrate being arranged against the first surface,
wherein the tube portion is shaped to receive in a first open end thereof a rigid cylindrical end portion of a mounting base, such as a pole for the luminaire head, wherein an inner surface of the tube portion as seen in a cross section perpendicular to the longitudinal direction has a closed shape dissimilar to an outer shape of the rigid cylindrical end portion of the mounting base, and
wherein the closed shape has at least three vertices touching a virtual inner circle such as to allow only a linear contact between the at least three vertices and the outer surface of the rigid cylindrical end portion of the mounting base.
