ABSTRACT:
A lamp has a base, a pole attached to and extending upwardly from the base, a shade having a central opening, and a neck assembly at an upper end of the pole supporting the shade. The neck assembly supporting the shade includes an outer neck member with an annular bottom plate attached to the top of the pole and an upper annular support ring. An inner neck member has an annular bottom plate and an upper annular ring, the inner neck member being coaxial with the outer member and having an axial length between the bottom plate and ring less than the corresponding length of the outer member. An externally threaded body passes through the bottom plates. A nut threadedly engages the threaded body and urges the bottom plates toward each other with the upper rings engaging opposite upper and lower surfaces of the shade adjacent the central opening. A halogen or incandescent bulb socket is supported in the inner neck member. In another embodiment, the outer neck member surrounds a coaxial threaded member which carries a spacer and bracket supporting the bulb socket.
