1. Field of the Invention
This invention relates to a flexible tubular shape decoration lamp, particularly to a flexible tubular shape decoration lamp which can be bent into various shapes as desired, for example, which can wind round frame, tree, display shelf and wall etc. for decoration.
2. Description of Prior-Art
In addition to illumination, lamp can be used for decoration purpose. For example, colorful lamp tubes or lamp-bulb strings are often used to wind round on trees or exhibited goods in National Day, Christmas and Lamp Festival etc., so as to enhance aesthetic effect.
Traditionally, lamp tube for above purpose is generally fluorescent lamp wrapped with some transparent papers having different colors or same color, while in the case of lamp-bulb string, it being lamp-bulb strings formed by a plurality of bulbs with different colors or same color connected by electrical wires.
Above lamp tube for decoration purpose, however, is made of glass that has no inflexibility. Furthermore, its appearance is usually limited to cylindrical as its sole shape, which is considered monotonous. While in the case of lamp-bulb string formed with bulbs connected by electrical wires, it has flexibility due to the flexibility of wire itself, however, it being out-of-date with its limited fineness and diversities for several decades, which is indistinctive in use.
Inasmuch as the foregoing status of the prior art, the inventor of this application has developed the inventive flexible tubular shape decoration lamp tube after intensive and wide research on above-mentioned lamp tube suitable for decoration use.
The flexible tubular shape decoration lamp tube of this invention not only has the advantages of both above-mentioned traditional lamp tube and lamp-bulb string, but also has diversified appearance to attain aesthetic effect.
In addition to flexibility itself, the flexible tubular shape decoration lamp tube of this invention is covered with cover body with its shape as desired on its outer wall, and the adjacent lamp bulbs being interconnected from head to tail in order by a connector to form a lamp tube string. When in use, therefore, lamp tube or lamp tube string can be bent through over various support bodies, e.g., trees, wall etc., and the light emitting from the light tube being permeable through the cover body. The outer surface of said cover layer is formed into irregular and flexible tubular shape, with its size being adjusted as desired, and can be formed into bumpy cahoots according to the shaped of the lamp tube string and the support body. Various colorful light can be emitted transversely along the direction of the lamp string, to enhance aesthetic effect of the decoration lamp tube through the outline of said cover body. Thus, this invention can provide delicate decoration and lamp-illumination effect to which traditional lamp tube and lamp string fail to attain.
This invention can be embodied in the way explained below. This invention provides a flexible tubular shape decoration lamp, comprising lamp string set formed by a plurality of lighting elements which are connected in series or in series and parallel combination by wires; and a support body which insulates and seals the components of said lamp string set by insulator material, providing with a connector at its one or both ends for interconnecting use; and cover layer, formed by insulator material, which surrounds said lamp string set and said support body, with its appearance having shape and pattern as desired. The appearance of said cover layer of this invention is formed into irregular, longitudinal bumpy cahoots, with its size being adjusted as desired, using the same material and color as that of said support body, or using two or more kinds of material with its distribution extending transversely, having two or more kinds of color extending transversely.
On the other hand, this invention provides a method for forming flexible tubular shaped decoration lamp, comprising the steps of:
The die used in this invention is formed by a multi-layer sleeve with each sleeve-layer having different bore diameter. The lamp string set and the support body pass through the innermost sleeve of the die. The plastic injection direction of the first extruding machine is the draw-out direction of the lamp string set and the support body, while the plastic injection directions of the rest extruding machines are each set at predetermined angle relative to the first extruding machine respectively. The outer layer and the inner layer of the multi-layer sleeve of the die have different center or different specification, and the operating condition being same or different. A plurality of extruding machines can extrude plastics material having same or different specification composition and color.
This invention provides another method for forming flexible tubular shaped decoration lamp, comprising the steps of:
This invention provides still another method for forming flexible tubular shaped decoration lamp, comprising the steps of:
This invention will be described in more details in reference to the accompanied drawings.
Referring to
As shown in
The lighting elements 11 of said lamp string set 1, for example, can be luminescent diodes or small bulbs, which are connected, in series or in parallel and series combination, with each other and supplied with power by electric wires 12. The support body 2 envelops and fixes said lamp string set 1 within it. A connector 21 is provided at both ends of the support body 2, so that the head portion and the tail portion of several support body 2 can be interconnected via said connector 21 into longer lamp string device. Said cover body 3 is made of insulator material, preferably plastic material. Furthermore, the shape of the inner wall of said cover body 3 is cylindrical for fitting to the outer wall of said support body 2, while the outer wall of the cover body 3 can be any shape or pattern as desired, e.g., crumple pattern as illustrated in drawing. The cover body 3 is also made of insulator material which can be the same or different insulator material as that of the support body 2. For example, it can be plastic insulator material with fluorescent feature to enhance colorful glittering.
