  • Publication number: 20150109782
    Abstract: An LED luminaire includes a thermal management system and features minimal glare while allowing for use of traditional luminaire housing. The luminaire of the depicted embodiments comprises a luminaire housing, an LED light module, an LED driver, a diffuser, and reflectors. The LED light module comprises at least one LED array, a primary thermal interface, and a secondary thermal interface. These thermal interfaces, particularly when used in conjunction with a conductive housing, allow for optimal thermal management by utilizing both natural convection and conduction to remove the heat from inside the luminaire into the surrounding air. Additionally, in certain embodiments, the position of the LED arrays within the housing in combination with the reflector design creates an optical path resulting in an indirect light source that minimizes glare, while providing a uniform distribution of light, unlike traditional LED luminaires.
