The present invention provides a sealed housing unit and a method for its manufacture, wherein the sealed housing unit can protect light-emitting elements and the connected electronic circuitry from moisture. The sealed housing unit comprises a thermally conductive base onto which an array of light-emitting elements is mounted. A frame is sealingly connected to the thermally conductive base circumferentially enclosing the array of light- emitting elements and connected circuitry. An optically transmissive panel sufficiently sized to span the area defined by the frame, is sealingly connected to the frame to form a sealed cavity enclosing the array of light- emitting elements and the connected circuitry. The light-emitting elements c an be electrically activated via electrical wires provided through one or more apertures within the thermally conductive base or the frame. Each aperture comprises a form of sealing means which suppresses the penetration of moistu re. |
