Abstract:
1. A method of manufacturing LED light string, comprising the steps of: (a) Preparing a plurality of printed circuit boards that may be folded toward one another in a predetermined manner, each of said printed circuit boards being provided with a positive and a negative electrode that are in square and round shapes, respectively, to enable easy identification thereof, and two connecting legs being separately connected to one predetermined positive and one predetermined negative electrode for connecting to a base later; (b) Folding said printed circuit boards to form a light body, disposing said light body into a light-transmissible shell, and then connecting said light body with said shell to a base to form a cluster lamp; (c) Preparing a plurality of lamp sockets, into each of which one said cluster lamp may be inserted; a plurality of conductors, each of which has two electrically terminals connected to two ends thereof; a power cord, an end of which is provided with a connector having a plug end and a socket end; and a plurality of top caps, each of which may be fitly closed to a rear bottom of each said lamp socket; (d) Separately inserting said two terminals at two ends of each said conductor into two insertion holes on two adjacent lamp sockets, so that said a plurality of lamp sockets are serially connected; and (e) Connecting a lampshade to an opening of each said lamp socket.
