<P>PROBLEM TO BE SOLVED: To prevent stress from being left in the leads of LED installed in the display part of an indicator board and a signboard, to save troublesome soldering work, to simplify the installation work of LED and to prevent the polarity of the LED lead from being mistaken at the time of installation work on site. <P>SOLUTION: A connector where the positive and negative leads of LED are inserted from one side and the LED leads are connected to lead wires inserted from the other side is used. The negative lead wire of the previous connector is inserted into the positive lead wire side of the next connector, and the negative lead wire of the connector is inserted into the positive lead wire of the next connector. The required number of connectors for LED are sequentially connected by the lead wires with a similar procedure so that series circuits are formed. <P>COPYRIGHT: (C)2003,JPO |
