Abstract:
1. An LED module comprising: an insulating substrate in plate form; a first main terminal and a first sub-terminal for connection to an external circuit formed in a vicinity of a first side of the insulating substrate; a second main terminal and a second sub-terminal for connection to an external circuit formed in a vicinity of a second side of the insulating substrate, the second side being opposite to the first side of the insulating substrate; three or more connecting wires formed on the insulating substrate for connecting LEDs in series, the LEDs being aligned side by side; a plurality of LEDs individually connected between the connecting wires that are adjacent to each other and connected in series in a same direction; a first passing wire formed on the insulating substrate for electrically connecting the first sub-terminal to the second sub-terminal, wherein a first connecting wire, which is one of the three or more connecting wires aligned side by side and is located on one side, is electrically connected to the first main terminal, and a second connecting wire, which is another of the three or more connecting wires aligned side by side and is located on other side, is electrically connected to the second main terminal; and a pair of electrodes for connection to terminals of a two-terminal element for short circuit formed on the insulating substrate, wherein one of the pair of electrodes for connection is electrically connected to the first connecting wire or the second connecting wire, and the other of the pair of electrodes for connection is electrically connected to the first passing wire.
