Patent ID: 7470055

Claim:
An LED lighting system comprising at least two homologous mounting structures, each of the homologous mounting structures comprising: at least one LED lighting source; a support body comprising a hollow body having a free space inside; a circuit board for mounting said at least one LED lighting source, said circuit board having conductive traces to feed electrical power to said at least one LED lighting source, wherein the circuit board is attached to a top of the support body; connectors to allow cascaded connection to other homologous mounting structures, said connectors comprising: a first connector receiving power from a power source or from a connector of a first one of the homologous mounting structures, a second connector providing the received power to a connector of a second one of the homologous mounting structures, wherein the first and second connectors are electrically connected such that a voltage of the power received at the first connector is substantially the same as a voltage of the power provided at the second connector, and wherein the first and second connectors are complementary with respect to one another; and a driver circuit for driving the at least one LED lighting source, wherein: the driver circuit provides electrical power received at the first connector to the at least one LED lighting source via the conductive traces of the circuit board, the driver circuit controls a drive current provided to the at least one LED lighting source, and the driver circuit is mounted within the free space of the support body, and the driver circuit provides power to and controls the current of only the at least one LED lighting source mounted on the circuit board of the mounting structure, wherein the at least one LED lighting source of each of the mounting structures is independently driven with respect to the LED lighting source of another mounting structure.
