A lamp holder (100) for LED light sources (30) is disclosed, comprising a passive heat sink (10), made by extrusion of a cylindrical aluminum body, on which the SMD-LED light source is fixed by a suitable support (20). Said support has an internal electric circuit, in turn connected to a connector (50) disposed in said support, for feeding the LED with previous connection of the connector to an external feeding source. The heat sink (10) and the entire lamp holder, may be fixed to a lamp by means of threaded connections (10a)made in the heat sink or tubular members to be attached to said heat sink. |
