<P>PROBLEM TO BE SOLVED: To provide a lighting device structured by arraying in parallel a plurality of boards mounting LED-mounting substrates on a ceiling part, and capable of easily performing an attachment work and a wiring work in a short time. <P>SOLUTION: The lighting device is provided with substrates 1 mounting LEDs 3, boards 14 each fitting the substrates 1, and electric wires 17 with connectors each having a connector 17b, 17c at either end. Each substrate 1 has a pair of input terminals 4a, 4b and a pair of feeding terminals 5a, 5b protruded from a rear face, each board 14 has a plurality of terminal holes into which the input terminals and the feeding terminals of the substrate 1 can be inserted, so that the terminals of the substrate 1 penetrate the terminal holes of the board 14 to mount the substrate 1 on the board 14 in a state protruded from a rear face of the board 14, and a plurality of the boards 14 mounting the substrates 1 are arrayed in parallel at the ceiling part, where, an input terminal of the substrate 1 at the foremost step is connected to a direct-current power source 15, and a feeding terminal and an input terminal of each adjacent two terminals are sequentially connected with the electric wire 17 with a connector, from the foremost-step substrate 1 to the hindmost-step one 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
