Abstract
A luminaire includes two housing halves, movable relative to each other between an open and closed configuration. The bottom housing half includes disposed therein a substrate which itself carries at least one LED which transmits light through a window in the bottom housing half. A thermal bridge made of at least one layer of anisotropic thermally conductive graphite is in thermal contact with the substrate and the top housing half when the housing is in the closed configuration, but its disengaged from either the substrate or top housing half when the housing is in the open configuration.
