Abstract

An artificial tree structure with decorative lamps, comprising a plurality of hollow tubes or iron wires of various lengths, in the shape of tree branches, arranged from top to bottom around the main trunk supported by detachable legs. On each side sticks are installed a plurality of iron wires to form the shape of tree branches. The exterior of the hollow tubes or iron wires is wound by dense tree leaves. The lamps installed in the hollow tubes or on the iron wires are serially connected to become decorative lamp strings. The decorative lamp strings are then combined in parallel connection, running down the main trunk to be connected to a control box and a power transformer. The structure described above provides the artificial tree with decorative lamps, using the control box to produce music and lighting effects of different luminosity and flashing speeds.

Claims

1. An artificial tree structure with decorative lamps, comprising:

a main trunk serving as a foundation;

a plurality of detachable legs disposed below a base of said main trunk and being equally spaced from each other;

a plurality of primary hollow tubes having various lengths and being disposed around said main trunk and roughly spaced equally from each other and arranged from a bottom to a top of said main truck in the shape of tree branches;

a plurality of secondary hollow tubes, at least one secondary hollow tube being connected to one of said primary hollow tubes to form further tree branches;

dense leaves disposed around an exterior of said hollow tubes;

a plurality of lamp bulbs, with at least one lamp bulb being disposed on each respective primary and secondary hollow tube; and

a plurality of electric wires, at least one electric wire being disposed at said main trunk, and at least one electric wire being disposed inside each respective primary and secondary hollow tube, the respective electric wires disposed inside the hollow tubes being electrically connected to the respective lamp bulbs and to the electric wire disposed in at said main trunk.

2. The artificial tree with decorative lamps of claim 1, wherein said main trunk is comprised of multiple sections joined together at joints, at the joints between the sections of said main trunk are protruded posts and depressed grooves that can be engaged to and disengaged from each other, and the electric wire at the main trunk is also divided in different sections joined together at joints, at the joints between the sections of the electric wire are installed plugs and sockets that can be engaged to or disengaged from each other.

3. The artificial tree with decorative lamps of claim 1, further comprising lamp holders installed on the hollow tubes, the respective electric wires inside the respective hollow tubes being connected with the lamp holders, the lamp holders can be electrically connected with or disconnected from the lamp bulbs.

4. The artificial tree with decorative lamps of claim 1, wherein the lamp bulb disposed on each respective hollow tube is located at an outermost distal end thereof so as to be coaxially arranged with said hollow tube.

5. The artificial tree with decorative lamps of claim 1, further comprising a control box for causing the lamp bulbs to flash on and off, and a power transformer for supplying power to the control box, the electric wire disposed at said main trunk being connected to said control box and to said power transformer.

6. An artificial tree structure with decorative lamps, comprising:

a main trunk serving as a foundation;

a plurality of detachable legs disposed below a base of said main trunk and being equally spaced from each other;

a plurality of hollow tubes having various lengths and being disposed around said main trunk and roughly spaced equally from each other and arranged from a bottom to a top of said main truck in the shape of tree branches;

dense leaves disposed around an exterior of said hollow tubes;

a plurality of lamp bulbs, with at least one lamp bulb being disposed on each respective hollow tube and at an outermost distal end thereof so as to be coaxially arranged with said hollow tube; and

a plurality of electric wires, at least one electric wire being disposed at said main trunk, and at least one electric wire being disposed inside each respective hollow tube, the respective electric wires disposed inside the hollow tubes being electrically connected to the respective lamp bulbs and to the electric wire disposed in at said main trunk.

7. The artificial tree structure recited in claim 6 wherein said lamp bulbs cap the ends of the respective hollow tubes.

8. The artificial tree structure recited in claim 6 further comprising lamp holders installed on the hollow tubes, the respective electric wires inside the respective hollow tubes being connected with the lamp holders, the lamp holders being electrically connectable with or disconnectable from the lamp bulbs, the lamp holders capping the ends of the respective hollow tubes.
