An LED lamp 100 has a heat dissipation structure 1 for removing heat from one or more LEDs in the lamp 100. The heat removal structure 1 has a central heat dissipation body (11, fig 2A,B) and cooling ribs 13 formed as a single integrated piece. The central body (11, fig 2A,B) has an outer side for accommodating the LEDs and an opposing inner side. The cooling ribs 13 have first and second ends (13a, fig 2A, 13b, fig 2B), the first ends (13a, fig 2A) connected to the central body (11, fig 2A). The cooling ribs 13 extend from the central heat dissipation body (11, fig 2A) and away from the inner side of the central body (11, fig 2A) to partially enclose an interior space and define open channels for heat convection flow into and out from the interior space over the surfaces of the cooling ribs. |
