Abstract
An improved fiber-optic illuminated artificial Christmas tree, having a plurality of light sources contained in the main trunk, is provided. Each light source provides light for one or more tiers of artificial branches attached to the main trunk. Each branch contains a plurality of fiber optic strands such that the light-gathering ends are collected in a single bundle at, or close to, the end of the branch which attaches to the main trunk and the light-dispersing ends are distributed throughout the needles of the branch to form a natural and appealing lighting appearance similar to that of conventional strings of Christmas tree lights. The light sources can be removed easily for replacement of individual light bulbs as needed.
Claims17
An artificial tree incorporating an integral lighting system, said artificial tree comprising:
- (1) a main trunk having a top end, a bottom end, a substantially hollow passageway extending substantially along its length, a plurality of branch-attachment openings disposed along its length, and a plurality of light-source openings along its length;
- (2) a base attached to the bottom end of the main trunk to hold the main trunk in an upright position;
- (3) a plurality of light sources for insertion into the light-source openings in the main trunk;
- (4) a plurality of branches for attachment to the main trunk at the branch attachment openings in the main trunk, wherein each branch has a substantially hollow passageway extending at least partially along its length, needles disposed along its length, and optic-fiber openings disposed along its length, and wherein the branches form a tree-like shape when attached to the main trunk;
- and
- (5) a plurality of fiber optic strands for each branch, wherein each fiber optic strand has a light-gathering end and a light-dispersing end, wherein the light-gathering ends of the fiber optic strands for each branch are formed into a single bundle in the hollow passageway of the branch at the end of the branch which attaches to the main trunk, wherein the single bundle of light-gathering ends for each branch is illuminated with at least one of the light sources contained in the main trunk, and wherein the light-dispersing ends of the fiber optic strands for each branch pass through the optic-fiber openings and are dispersed throughout the needles of the branch.
An artificial Christmas tree comprising a hollow main trunk having disposed therein a plurality of light sources;
- a plurality of branches attached to the main trunk wherein each branch has a passageway therein for passage of fiber optical strands, a plurality of outlet holes arranged along the length of the branch, and a plurality of needles attached along the length of the branch;
- a plurality of fiber optical strands for each branch wherein each fiber optic strand has a light-gathering end and a light-dispersing end;
- and a secondary trunk structure attached to the top of the main trunk;
- wherein, for each branch, the fiber optic strands are located within the passageway such that the light-gatherings ends of the fiber optic strands can gather light from one of the light sources in the main trunk and the light-dispersing ends of fiber optic strands extend from the passageway in the branch through the outlet holes and are dispersed throughout the needles attached to the branch;
- and
- wherein said secondary trunk structure has
- (1) a secondary trunk having a substantially hollow passageway extending substantially along its length, a plurality of needles attached along its length to form a generally conical shape, and a plurality of optic-fiber openings located along its length, wherein the bottom of the secondary trunk is adapted to attach to the top of the main trunk;
- and
- (2) an additional plurality of fiber optic strands, each fiber optic strand of the additional plurality having a light-gathering end and a light-dispersing end, wherein the fiber optic strands pass through the optic-fiber openings in the secondary trunk and down the passageway in the secondary trunk toward the bottom end of the secondary trunk, wherein the light-gathering ends of the additional plurality of fiber optic strands are formed into a single bundle near the bottom of the secondary trunk in order to gather light from the upper-most light source in the main trunk, and wherein the light-dispersing ends of the additional plurality of fiber optic strands are dispersed throughout the needles attached to the secondary trunk;
- whereby the secondary trunk structure and the plurality of branches attached to the main trunk form a Christmas tree-like shape.
