An LED lighting fixture has a plurality of LEDs mounted on a board, together forming an LED module. A covering is provided on the LED module on an opposite side of the board relative to the LEDs. The covering has at least one fin extending substantially perpendicular to the LED module. Each fin has an internal channel in which a heat-conducting element is provided. The heat-conducting element has a greater thermal conductivity than the fin and is substantially encapsulated by the fin.
