Abstract: Illumination device which comprises multiple illumination modules, each provided with a corresponding group of light sources. A liquid cooling plant is connected to the light sources in order to dissipate heat generated by the latter. The cooling plant is provided with a heat exchanger comprising a manifold provided with a passage channel having an inlet branch and an outlet branch. The heat exchanger further comprises a transmission block, which carries the illumination modules mounted thereon and is provided with multiple cooling tracks, which are hydraulically connected, parallel to each other, to the inlet branch and to the outlet branch of the passage channel of the manifold. Each cooling track is arranged at a respective illumination module in order to transfer the heat generated by the light sources of such illumination module to a coolant fluid which traverses the cooling track.

Abstract: A light source cooling body (100), a light source assembly, a luminaire and a method to manufacture a light source cooling body or a light source assembly are provided. The light source cooling body comprises a homogeneous body (104) made of a thermally conductive material. The homogenous body comprises an open space that comprises a wick structure, a condenser (112) and an evaporator (116). Near the evaporator the light source cooling body has an interface area (102) to thermally couple with a light source and to receive heat from the light source. The condenser is arranged away from the interface area. A portion 114 of the open space is tubular shaped. The open space may hold a cooling liquid partially in the gaseous phase and partially in the liquid phase and the wick structure is configured to transport the cooling material in the liquid phase towards the evaporator.

Abstract: An outdoor area LED lighting system including: a housing containing a large array of LEDs mounted to an aluminum direct thermal path printed circuit board and a single lens. The large array of LEDs are capable of producing light rays directed through the single lens to produce a beam of light to illuminate the outdoor area. The single lens is preferably a Fresnel lens. The housing is preferably capable of being sealed in a weather-tight manner. A second housing may at least partially surround the first housing such that at least one air passage is provided between the first housing and the second housing. A heat sink including a heat block in thermal communication with a plurality of heat tubes and fin assemblies may be in partial thermal contact with the LED module and in fluid communication with the at least one air passage. At least one fan may be provided in or in fluid communication with said at least one air passage to cool the heat sink. A digital interface may connect the LED module to a host computer to monitor and track information and trending for statistical process control.
