A thermosyphon light engine and luminaire including the same are provided. The light engine includes a condenser, an evaporation chamber, and a connecting element therebetween. The condenser returns a gaseous substance located therein to a liquid substance. The evaporation chamber includes a solid state light source, a working liquid, and an optical element that beam shapes light emitted by the at least one solid state light source. The solid state light source is immersed in the working liquid, such that heat generated by the solid state light source changes the working liquid into a gaseous substance. The gaseous substance travels through the connecting element to the condenser, which returns the gaseous substance to a liquid substance. The liquid substance then travels through the connecting element back to the evaporation chamber.

Thermosyphon light engine and luminaire including same

A solid state light source module having a compact, thermally enhanced substrate with one or more recessed pockets, is provided. The module includes a solid state light source and an electrical connection for the solid state light source, such that it is able to receive power so as to generate light. The solid state light source is connected to a substrate having an upper surface and a lower surface. The substrate includes a recessed pocket in the upper surface, defined by a wall and a floor that are at least large enough to accommodate the solid state light source; thus, the solid state light source sits within the recessed pocket. This allows the module to be substantially flat, even with an attached optical system, even utilizing remote phosphor technology, and increases the amount of heat dissipated by a thermal management system that is part of, or connected to, the module.

Compact, thermally-enhanced substrate for lighting applications

A thermal management system for a display case having a corner in which a lighting system is located is provided. The lighting system includes a reflector and a light source that generates heat and is mounted with the reflector. A lighting system support is positioned in the corner of the display case and is associated with the lighting system. A mullion is positioned between the lighting system support and the lighting system. The mullion maintains a desired relative position between the lighting system support and the lighting system. A contactor is located between the lighting system support and the lighting system, and provides minimal thermal conduction between the lighting system support and the lighting system. The contactor thus reduces heat transfer from the heat-generating light source to the lighting system support, thereby reducing an amount of heat transferred to the corner of the display case.

Thermal management solution for case corner lighting system

A luminaire with a thermal pathway to reduce the junction temperature of the luminaire's light source, and methods for so doing, are disclosed. The luminaire includes a can, a light engine, and a trim, that define a substantially continuous thermal pathway from the light engine to a surrounding environment. The can defines a can cavity and includes a can end region. The light engine is within the can cavity and includes a light source and a heat sink, including a heat sink end region, coupled thereto. The trim is at least partially disposed within the can cavity and includes a first trim end region coupled to the heat sink end region and a second trim end region coupled to the can end region. Thermal interface material may be located between: the heat sink and the trim, the trim and the can, and/or the heat sink and the light source.

Thermal trim for luminaire

A lamp assembly, and method for making same. The lamp assembly includes first and second truncated reflector cups. The lamp assembly also includes at least one base plate disposed between the first and second truncated reflector cups, and a light engine disposed on a top surface of the at least one base plate. The light engine is configured to emit light to be reflected by one of the first and second truncated reflector cups.
