An LED light assembly comprises an aluminium extrusion cut to length to form a heat sink (20) with a hollow interior that may be semi-circular in cross-section or any other convenient cross-section to allow air flow through the heat sink and including a mounting surface (21) for supporting and conveying heat from an LED light source (62) mounted on the surface. The extrusion has a heat dissipating surface (24) with fins (27) for receiving and dissipating heat from the LED light sources (62) on the mounting surface (21). The fins (27) support items such as anchors (45), brackets (37) and casings (28, 35) also formed by lengths of respective extrusions and a sliding fit on the heat sink (20). |
