  • Publication number: 20110043090
    Abstract: The present invention is to provide a lamp structure improvement in the two-lamps typed decoration lamp string. Each lamp body of the said lamp string is composed of a single soft head, a single soft core and a LED single body of the ordinary half-shaped type separately package-covered with a single lighting crystalline grain then leaned against each other to form a lamp of ordinary shape-and-sized single-piece LED such that the mutually assembled and formed single-piece-shaped LED can have two lighting crystalline grains and form a two-lamps typed lamp body. It thus can effectively lower the manufacturing cost of lamp body in the two-lamps typed decoration lamp string.
