ABSTRACT:

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 disclosed the first light in the 1880s, many kinds of illuminations have been used, thus allowing life at night to become diversified. The illuminations are used for adornment and in brightening. The power of light emitted is qualified as Ohm's law as W=V
2
/R, wherein the V is denoted as the loading voltage of the circuit and R stands for resistance. Otherwise, the principle light emitting is indicated as the “Black body emission” principle. The principle indicates the relationship between the wavelength of emitted light and the temperature of the emitting source (for example, the human being emits the IR at room temperature). Hence, 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 chemically stable at a high temperature. Referring to
FIG. 1
is a cross-sectional view of a conventional light
10
is shown therein.
More complex structures of light, such as a light containing a fuse, have been developed. The fuse of the light is used to prevent the excess use of electric power. The light containing the fuse is shown as FIG.
2
. 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
20
are contained in a casing
21
. All of the elements are mounted in the following sequence: The couple of wires
22
are fitted through the bottom of the casing
21
wherein the pinnacles of the couple of wires
22
are formed as hooks. Further, the filament
23
is hooked between the hooks of the couple of wires
22
. Moreover, a fuse
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 fail due to all of the lights on the circuit of the string. The fuse
25
is used for preventing all of the lights on the string from being disabled. For insulation, an insulator ball
24
is used between the couple of the wires for a fixing purpose.
In the light
20
described above, the fuse
25
is usually wound around the couple of wires
22
. The fuse
25
may loosen when the filament is heated at high temperature. When the lights of ornaments are unavoidably shifted, the wires are easily loosened with the wires
22
.
SUMMARY OF THE INVENTION
According to one aspect of the invention, there is provided a new type of light. The disclosed new type of light has the excellent coupling reliability of the fuse. Therefore, the light of the present invention has the advantage of preventing vibration of the surroundings.
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 loosing 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, particularly, and the advantages of the invention will be more readily apparent from the reading of the following detailed description of the invention taken in conjunction with the accompanying drawings.
