Abstract: A luminaire includes a fixture to be generally received in a recess of a support surface. A plurality of light engines are disposed within the fixture. The light engines each have at least one light source. A heat flange disposed about a distal end region of said fixture. The heat flange having a hollow, generally frustum shape with a cross-section extending generally radially outwardly beyond said fixture and extending away from said distal end region of said fixture. The hollow shape provides a flange cavity for housing of driver or other components for the light engines.

Abstract: Reflector-type lamps and housings with integrated heat distribution and EMI shielding are disclosed. A reflector-type lamp includes a lamp housing having a base portion, a reflector portion, and an integrated heat distribution structure. A light source may be located in a reflector housing region or cavity defined by the reflector portion and integrated electronics may be located in a base housing region or cavity defined by the base portion. In general, the heat distribution structure distributes heat from hot spots in the lamp to exterior locations along the base portion and/or reflector portion. The heat distribution structure may also provide electromagnetic interference (EMI) shielding when EMI is generated within the lamp, for example, in the integrated electronics.
