Patent ID: 7880389

Claim:
A light-emitting-diode lighting lamp, comprising: a plurality of light-emitting diode elements arranged at each of side surfaces of a polygonal supporting member; a pair of cathode and anode terminal electrodes disposed at one end portion of each of the side surfaces of the polygonal supporting member, the pair of cathode and anode terminal electrodes being electrically connected to the plurality of light-emitting-diode elements disposed at the corresponding each of the side surfaces of the polygonal supporting member; and a socket in which the one end portion of each of the side surfaces is inserted, the socket being detachably attachable to the one end portion of the side surfaces and having a pair of output terminals electrically connected to the pair of cathode and anode terminal electrodes at the one end portion of each of the side surfaces, the pair of cathode and anode terminal electrodes at the one end portion of each of the side surfaces being disposed at mutually shifted positions in a direction that the one end portion of each of the side surfaces is inserted in the socket.
