Abstract: A recessed light fixture has a heat sink and a removable light engine assembly. A thermally conductive base of the light engine assembly has an LED and has a thermal interface adapted for thermal coupling to a thermal interface of the heat sink. A mechanical connector in the enclosure can connect the base of the light engine assembly to the heat sink and couple the thermal interfaces of the light engine assembly and heat sink. The base of the light engine assembly is insertable through an opening in the ceiling aligned and can be urged into connected and disconnected states, from within the room, with a minimal clearance between the opening in the ceiling and the base, whereby the light engine assembly can be replaced or serviced from within the room without disturbing the ceiling and without the use of a large diameter trim.
