1. A driving arrangement for driving a set of appliances, comprising:a set of driving circuits, wherein each driving circuit include,
a two-line power input;
a first output for connection to one of the set of appliances;
a second, two-line, output;
an internal energy source; and
a switching arrangement, wherein the second, two-line, output is coupled to the two-line power input via the switching arrangement and the switching arrangement is configurable into,
a first mode, in which the two-line power input is connected to the second, two-line, output, and the internal energy source is isolated from direct connection to the two-line power input; and
a second mode in which the internal energy source is in series between a first line of the two-line power input and a corresponding first line of the second, two-line, output;
wherein the set of driving circuits are connected together in a chain, with the second, two-line, output of one of the set driving circuits connected to the two-line power input of next one of the set of driving circuits in the chain, wherein each driving circuit is for driving a respective appliance.
