Publication number: 20130221245Abstract: A lighting module has an array of light-emitting elements that is electrically coupled to a heat sink and a housing having a heat exit. The array of light-emitting elements is positioned in the housing and the heat sink is positioned to dissipate heat generated within the housing so that the heat is expelled through the heat exit.
