The light bulb group of a known decoration lamp string generally includes a lamp stand, a linking seat and a light bulb that are composed as a unity. The light of a light bulb is utilized to exhibit the decoration or twinkling effects. But, this kind of structure is only illuminated out directly the light generated by the light bulb, and there is no specialty at all worthwhile to be mentioned. Thus, a kind of light bulb group covered with an outer shell that can generate dazzling shining effect is designed as the newer design described in the U.S. Pat. No. 7,325,942 which is a light bulb covered by an outer shell with a single flowered shell, and a solid arborescence branching body is formed on the outer shell. Through this, while the light bulb is lightening, the beam is passing through the flowered shell and generating a more dazzling light through the refraction of each branching body. However, the light of this kind of light bulb group is only illuminated out through the single flowered shell of outer shell. The generated illustrated face is also limited to the said face of the followed shell of outer shell. Furthermore, due to the small space covering the light bulb, the heat dissipation effect is bad and the light bulb is easy to be damaged unless a hole is opened in the flowered shell. But the beauty and expected effect will be damaged through doing this, thus it still waits to be improved.
The present invention is a kind of outer shell structure of a decoration lamp string, which mainly uses two or more than two flowered shells to be linked together to form an outer shell of light bulb with several flowered shell linking bodies to let the light bulb generates more light illustrating faces. Simultaneously, it is hard to be overheated due to the increasing space of light bulb, thus the life of usage is increased and the practical effects are obtained. The structure and characteristics of the present invention are described hereafter by referring to following drawings.
Please refer to those shown in
Through the aforementioned design, each light bulb group in the decoration lamp string all set with a light bulb 20 covered by an outer shell 10 with several flowered shells 11 linking bodies such that the light lightened by the light bulb 20 is illustrated out through each flowered shell 11 by this outer shell, and more light illustrating faces can be generated to let the light source generated by a single light bulk 20 becomes more dazzling shining. Simultaneously, it is hard to be overheated due to the design of several hollow flowered shells 11 which can increase the space in covering light bulb, and its life of usage is thus increased.
However, the aforementioned are only demonstrative examples in the present invention, and are not used to restrict the range of the present invention. Thus, all modification implemented under the same creative originality shall be covered by the present invention.
