Embodiments of the present invention describe novel solid core doors and methods of manufacturing solid core doors that use specialized dovetail joints to secure components of the door together to improve the sturdiness and aesthetics of the door. The manufacturing processes can include applying glue to joints between components, and pressing the door from the sides to secure the components together in a way that improves the sturdiness of the door.

A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, a power converter such as an AC/DC converter operably associated the door frame, and a DC electric device mounted to the door and electrically connected to the AC/DC converter. The AC/DC converter is configured to be electrically connected to an AC power unit operably associated with the door system.
