A new type of light includes a casing used for containing an emitting device. Further, the emitting device includes a couple of wires, an insulator ball, a filament and a fuse. The couple of wires are connected with a power supply via the casing, wherein the contact points of wires and casing are defined as the bottom of the light. Moreover, the insulator is posited above the bottom of light. Subsequently, the filament is posited above the insulator ball, and the fuse is posited on the top of wires. Particularly, the tops of wires are wound to form hooks to hold the fuse. The hooks are flattened for increasing the adhesion of connection between wires and fuse.
Description




FIELD OF THE INVENTION




The present invention generally relates to a new type of light, and more particularly, relates to a new type of light comprising a filament, a fuse, a couple of conductors and an insulator. Further, the relative position between the filament and the fuse is changed to improve the reliability of the light.




BACKGROUND OF THE RELATED ART




Since T. A. Edision has disclosed the first light in 1880s, the human being uses many kinds of illuminations. So that the life in the night becomes more diversiform. The illuminations are used in adornment and in brightening. The power of light emitting is following as Ohm's law as W=V


2


/R, wherein the V is denoted as the loading voltage of the circuit and R is indicated as the resistance. Otherwise, the principle of light emitting is indicated as the “Black body emission” principle. The principle indicates the relationship between wavelength of emitting light and temperature of emitting source (for example, the human being emits the IR at room temperature). Hence, the visible light can be generated by using a suitable material, such as tungsten, which the tungsten is preferably heated to about 3,000° C. The suitable material must be chemical stable at the high temperature. Referring to FIG.


1


, a cross sectional view of a conventional light


10


is shown therein.




Furthermore, the accumulation of experiences in the human's life, people has developed more complex structure of light, such as a light containing a fuse. The fuse of the light is used to prevent the excess of using electric power. The light containing the fuse is shown as FIG.

. The light


20


is composed of a tungsten wire


23


, a fuse


25


, an insulator


24


and a couple of wires


22


. All of the elements of the light

25


is wound around the couple of wires


22


for protecting the circuit, wherein the position of the fuse


25


is under the filament


23


. In a string of lights, one or more lights are failure due to all the lights on the circuit of the string. The fuse

22


.




SUMMARY OF THE INVENTION




According to one aspect of the invention, there is provided a new type of the light. The disclosed new type of the light has excellent coupling reliability of the fuse. Therefore, the light of the present invention has the advantage to prevent vibration of the surroundings.




In one embodiment of the present invention, the disclosed light is composed of an insulator ball, a filament and a fuse connected to a couple of conductive wires in a sequence from the bottom of the light. Further, all of the components are contained in a casing.




In another embodiment of the present invention, the light is also composed of an insulator ball at the bottom, a filament disposed atop of the conductive wires, a fuse disposed between the insulator ball and the filament. In order to prevent loosened of the fuse, the fuse is fastened in one end with two spiral circles for clockwise direction and another end with two spiral circles for counterclockwise direction.




The above and other features, particularity, and advantages of the invention will be more readily apparent from reading of the following detailed description of the invention taken in conjunction with the accompanying drawings.

FIG. 2

shows a cross-sectional view of a prior art of a light with a fuse;





FIG. 3

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIG. 3

, the light


30


according to a first embodiment of the present invention is composed of a filament


33


, a fuse


35


and an insulator ball


34


wherein all of them are connected between a couple of wires


32


. Further, all of the components are contained in a glass-casing


31


, and the wires


32


are connected to a power supply outside the casing


31


.




According to the present invention, the casing


31


can be the material selected from a group consisting of glass, color glass and any kinds of color plastic casings. The casing contains an emitting device which will radiate light beam, a couple of wires


32


extends from the casing


31


and couples to the power supply. The wires can be formed by an alloy, such as the copper and magnesium.




The emitting device in the casing


31


consists of the couple of wires


32


wherein an insulator ball


34


is located at the lower end of the wires


32


near bottom of the casing


31


and space apart the wires


32


to provide insulation of the wires


32


, a fuse


35


is located atop the wires


32


, and a filament


33


is disposed between the insulator ball


34


and the fuse


35


. The connecting points of the wires


23


and casing


31


is defined as the bottom of the light


30


. The detailed position of the components of the emitting device is as following: The insulator ball


34


is positioned about 10-20 mm from the bottom of the light


30


. The insulator ball


34


is selected from a group consisting of glass, ceramic or plastic. Successively, the filament


33


is positioned about 5-10 mm above the insulator ball


34


. Finally, the fuse


35


is positioned on the top of the couple of wires


32


wherein the top of wires are wound as hooks to connect to the fuse


35


, and the distance between the top of wires


32


and filament


33


is about 3-4 mm. In order to fasten the fuse


35


and wires


32


, the hooks are pressed and flattened. By pressing the hooks of the wires


32


, the connecting function between the fuse


35


and wires


32


become more rigidly. According to the first embodiment of the present invention, the reliability of the connection between fuse


35


and wires


32


is increased. Therefore, the problem of the conventional ornament lights that are easy failure according to the vibrations from the surroundings can be resolved.




Referring now to

FIG. 4

, the figure shows a second embodiment of the present invention. Due to the unreliable fixing of the fuse of conventional light, the present embodiment introduces a new structure to fix the fuse


35


. In this figure, the emitting device also includes a pair of wires


32


disposed within the casing


31


. The insulator ball


34


separated the wires


32


and is positioned about 10-20 mm from the bottom of the light


30


. Next, the filament


33


is located atop the wires


32


and fixed according to the conventional method. Moreover, the fuse


35


is configured above the insulator ball


34


about 5-10 mm. The winding method of the fuse


35


is as follows: one end of the fuse


35


winds on one of the wires


32


with two spiral circles in clockwise direction, the other end of the fuse


35


winds on another one of the wires


32


also with two spiral circles, but in counterclockwise direction.




By using the new structure of the light, the conventional failure mode of disconnect is also avoided. Furthermore, since the length of the fuse


35


according to the second embodiment of the present invention is much shorter than conventional light, power consumption of the present invention can be reduced.




However, the sizes described above are an example such as an ornament light in celebration, and the present invention would be constricted according the sizes. While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
