Abstract
Abstract Illuminated decorative displays utilizing fiber optics are presented. The decorative displays are in the form of Christmas season ornaments such as wreaths, Christmas trees, and outdoor lighting series. The simulation of light bulbs is achieved by transmitting light through a solid light conducting medium. In the case of the Christmas tree, a cast solid medium in the form of a coniferous branch is used. In the case of the wreath, either a solid light conductive medium cast in an annular shape, or a hollow annular chamber with perforations filled with optical fiber material is used. In the case of the lighting series, either a long case rod with protrusions, single or bundled group of optical cable is used.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
178 words
An illuminated decorative display in the form of a Christmas tree, including a structural housing with an enclosure wall in the form of a hollow tubular trunk of the tree, a light source extending throughout the hollow trunk, in the form of an elongated tubular light, solid light conducting members made of cast organic material each having a stem portion and branch portions cast and extending from the stem portion in such a manner that the stem portion and branch portions transmit visible light to the ends of the branch portions and the stem portion, the light conducting members forming the tree branches of the Christmas tree with the one end of the tree branch penetrating a discrete opening in the hollow tubular trunk and being in close proximity to the light source and the branches of the light conducting member being in the form of evergreen needles extending from the stem of the tree branch such that light is emitted at the end of the stem and at the end of the needles of the tree branch.
Claim 2
Dependent Claim
178 words
An illuminated decorative display in the form of a Christmas tree, including a structural housing with an enclosure wall in the form of a hollow tubular trunk of the tree, a light source extending throughout the hollow trunk, in the form of an elongated tubular light, solid light conducting members made of cast organic material each having a stem portion and branch portions cast and extending from the stem portion in such a manner that the stem portion and branch portions transmit visible light to the ends of the branch portions and the stem portion, the light conducting members forming the tree branches of the Christmas tree with the one end of the tree branch penetrating a discrete opening in the hollow tubular trunk and being in close proximity to the light source and the branches of the light conducting member being in the form of evergreen needles extending from the stem of the tree branch such that light is emitted at the end of the stem and at the end of the needles of the tree branch.
Claim 3
Dependent Claim
64 words
A Christmas tree as defined in claim 1, wherein one end of the tubular light is fitted within an electrical conducting socket, and the socket is mounted for rotation being directly connected to a motor in a base of the Christmas tree, and the other end of the tubular light is in contact with an electrical contact cover at the end of the trunk.
Claim 4
Dependent Claim
37 words
A Christmas tree as defined in claim 2, wherein the electrical connection for the light is supplied by a rotary segmented conductor disc which provides intermittent electrical contact to the socket for intermittently lighting the Christmas tree.
Claim 5
Dependent Claim
61 words
A Christmas tree as defined in claim 2, wherein the tree branch formed by the light conducting material is molded in one piece with a stem and a plurality of branches in the form of evergreen needles extending radially from the stem, the stem and branches in the form of evergreen needles being capable of conducting light to the ends thereof.
Claim 6
Dependent Claim
145 words
An illuminated decorative display comprising a structural housing with an enclosure wall in the form of an annular wreath having a hollow tubular housing defining a ring, a chord-like tube extending across the ring with the ends of the chord-like tube in communication with the annular tubular housing, at least one light source provided in the tubular housing adjacent the chord-like tube, a solid light conducting member formed of a cast organic material formed as a stem portion and branch portions such that the stem portion and branch portions transmit visible light to the ends of the branch portions and the stem portion, one end of the light conducting stem being in close proximity to the light source, and the stem thereof extending axially of the chord-like tube and the branches extending therefrom coincident with apertures provided in the chord-like tube for emitting light therefrom.
Claim 7
Dependent Claim
145 words
An illuminated decorative display comprising a structural housing with an enclosure wall in the form of an annular wreath having a hollow tubular housing defining a ring, a chord-like tube extending across the ring with the ends of the chord-like tube in communication with the annular tubular housing, at least one light source provided in the tubular housing adjacent the chord-like tube, a solid light conducting member formed of a cast organic material formed as a stem portion and branch portions such that the stem portion and branch portions transmit visible light to the ends of the branch portions and the stem portion, one end of the light conducting stem being in close proximity to the light source, and the stem thereof extending axially of the chord-like tube and the branches extending therefrom coincident with apertures provided in the chord-like tube for emitting light therefrom.
Claim 8
Dependent Claim
89 words
An illuminating display device in the form of an outdoor-indoor series light comprising an elongated tubular structural housing, a light source provided at one end of the tubular housing, and light pipes extending within the housing from the light source with one end of the light pipes being in close light conducting proximity to the light source, a plurality of discrete openings in the housing, and the individual light pipes being bent to pass through said discrete openings in the housing to thereby provide a series light display device.
Claim 9
Dependent Claim
89 words
An illuminating display device in the form of an outdoor-indoor series light comprising an elongated tubular structural housing, a light source provided at one end of the tubular housing, and light pipes extending within the housing from the light source with one end of the light pipes being in close light conducting proximity to the light source, a plurality of discrete openings in the housing, and the individual light pipes being bent to pass through said discrete openings in the housing to thereby provide a series light display device.
Claim 10
Dependent Claim
41 words
An illuminating device as defined in claim 6, wherein the tubular housings are in the form of straight cylindrical tubes connected to light source housings, and a plurality of such tubes may be provided in series interrupted by light source housings.
Claim 11
Dependent Claim
86 words
An illumination display as defined in claim 6, wherein the solid light conducting members are in the form of light pipes and the light source is contained within an enclosed housing having means for receiving the light pipes, the light source including means for providing intermittent or colour changes is provided within the light source housing such that sequential intermittent or light colour changes can be provided by means of a plurality of light pipes being sequentially exposed to the intermittent light means or colour changes.
Claim 12
Dependent Claim
45 words
A display as defined in claim 8, wherein an opaque wheel driven by a motor is interposed between the ends of the light pipes and the light source and openings are provided in the opaque wheel for providing sequential intermittent effect to the light pipes.
