Abstract
Lamps LP1-LP9 are connected in a matrix form. Control devices Tr1-Tr6 are installed on connecting wires of the lines and rows of the matrix used for connecting the lamps LP1-LP9, respectively. Each of the connecting wires L1-L3 on each line is connected to a power supply Vcc via each of the control devices Tr1-Tr3. Further, each of the connecting wires L4-L6 is connected to the ground via each of the control devices Tr4-Tr6. Then the plurality of loads are connected to the control devices Tr1-Tr6 so as to control the loads by the control devices Tr1-Tr6, the number of which is smaller than the number of loads.
