Abstract

There is provided a light fixture, comprising a heat sink element and an upper housing mounted to the heat sink element, the heat sink element extending farther in a first direction in a first plane than a largest dimension of the upper housing in any plane parallel to the first plane. In addition, a light fixture, comprising a heat sink element, an upper housing mounted to the heat sink element and an additional component (e.g., a power supply module or a junction box) in contact with the heat sink element. Also, a light fixture, comprising a heat sink element, an upper housing thermally coupled to the heat sink element and at least one solid state light emitter thermally coupled to the heat sink element.
