1. A linear fixture for protecting and removing heat from a light-emitting element, the light-emitting element having a thermal-interface surface that is substantially planar, and the light-emitting element having an electrical connector with one or more electrically conducting terminals emerging normal to the thermal-interface surface, the linear fixture comprising:
a heat sink having a first end and a second end, the heat sink extending along a length axis from the first end to the second end, and the heat sink having a substantially uniform cross section in planes normal to the length axis between the first end and the second end; the heat sink including a top wall portion, a bottom wall portion, a right wall portion, and a left wall portion, the four wall portions together encompassing on four sides an interior space; the bottom wall portion having on its side opposite the interior space a mounting surface of areal extent sufficient to allow contact with the thermal-interface surface of the light-emitting element; the bottom wall portion also having a connection port through which the one or more electrically conducting terminals emerging normal to the thermal-interface surface of the light-emitting element may pass to reach the interior space; and the interior space having disposed within it an electrical assembly including an electrical assembly connector positioned to make electrical contact with the one or more electrically conducting terminals.
