Abstract: The expandable pendant lamp contains a number of lamp units, each having at least a light generation element. The lamp units are vertically stacked and any two adjacent lamp units are connected by a number of flexible linear elements. For each pair of adjacent lamp units, magnetic elements are configured along the interfacing faces of the lamp units, respectively so that magnetic attraction therebetween would pull the adjacent lamp units together. The expandable pendant lamp, as it is hung from a ceiling, could have its lamp units vertically stacked together or the lamp units are separated apart to hold various objects such as utensils and decorators.
