发明名称 Changeable visual display lamp
摘要 An improved changeable visual display lamp, having the ability to accept single piece cylinder sheets of artwork, or other items for display, where the cylinder is able to be inserted into the confines of an annular tubing through the removal of a single piece of the lamp. The two variations of this lamp allow cylindrical items to either be inserted through the bottom of the lamp by the removal of a single plate, or through the top of the lamp, through the removal of a single ring, where the ring covers a circular gap that extends around a centrally located socket. No tools are necessary to change the item or items being displayed, the person changing the display is not exposed to electrical shock, and the time required to change the display is reduced to a nimum. Benefits of the ring are seen where the ring may be removed, and single piece cylinder artwork is removed or inserted, without even unplugging or disassembling the lamp, other than manipulation of the single ring.
