Abstract: A built-up table lamp includes a lamp stand formed by bending a fan-like sheet of flexible material to define a truncated-conic structure having a larger lower end standing on table and a small upper end to support a bulb socket assembly. An inner truncated-cone is received within the upper end of the lamp stand and an outer truncated-cone is fit over the upper end of the lamp stand to sandwich therebetween the upper end of the lamp stand. The bulb socket assembly includes a socket having a threaded tube mounted to the bottom thereof to insert through holes formed on the truncated-cones to be secured thereon by a nut. A lamp shade is formed by bending a fan-like sheet of flexible material to define a truncated-conic structure. The lamp shade has a plurality of holes formed thereon to receive and nut-secure thereon a threaded end of each of a plurality of harp rods of which the other ends are threadingly engaged to inner-threaded holes formed on a ring.

Abstract: The present invention is aimed to provide a lamp with collapsible arm, the collapsible arm comprises bottom, intermediate, and top sections telescopedly connected to each other, and a conductive assembly disposed in the sections to facilitate electrical communication therebetween, so that the collapsible arm can be adjusted to a desired position by way of moving the sections forward and backward without losing electric contact therebetween.

Abstract: A desk lamp which may be easily assembled and disassembled is composed of a base, an arm and a shade, wherein wires extending along the arm and the arm itself have opposite ends which are insertable and removable from corresponding pairs of pins and recesses in the base and shade.
