Abstract: A lamp which can easily be disassembled and assembled comprising a frame structure composed of a plurality of frame units, upper and lower holders for holding three or more of said frame units in combination and a light globe socket on said upper or lower holder; and shade plates detachably engaged with the frame units respectively for enclosing said socket and defining the peripheral construction of the lamp. Said frame unit has a vertical pillar and a pair of frame arms transversely extending therefrom, the intermediate portion of the frame arms being bent to make an obtuse angle (about 120.degree.). A plurality of said frame units are put together with the bent portion of the frame arms being inside and facing each other, and held by said upper and lower holder, then a light bulb socket is mounted on the upper or lower holder. Finally, the shade plates are slid along the pillar and are fixed to the frame units respectively to finish the lamp.
