The present invention relates to a power cord or cable, particularly to an electroluminescence power or signal cable.
The conventional power cable, communication cable and signal cable can not indicate whether it is in live state, and also can not indicate the direction of the current in said cable.
It is known that the electroluminescence cable is widely used for decorating the lamps. For example, CN 02115607.7 disclosed an electroluminescence cable and a method for producing the same. The electroluminescence cable consists of at least a linear conductor as a central electrode, a layer of insulating material applied on the central electrode, a electroluminescence layer of mixture of fluorescent powder and binder applied on the layer of insulating material, a transparent conductive layer composed of nano grade conductive substance which the diameter of particle is equal to or smaller than 20 nm applied on the electroluminescence layer, the nano grade conductive substance as the transparent conductive layer also penetrate into the gaps formed in the mixture of the fluorescent powder and binder as the electroluminescence layer and at least a linear conductor as an outer electrode wound in spiral form on the above transparent conductive layer.
To overcome the above drawback in the prior art, an purpose of the invention is to provide a current-seen cable which assemble an electroluminescence cable and various power cord or signal cord, which is simple in structure and can visually indicate the live state of it.
The above purpose is achieved by providing a current-seen cable, said cable includes a main cord as a power cord or a signal cord and a plurality of electroluminescence cords, said a plurality of electroluminescence cords are arrayed abreast and are intertwisted helically in sequence to be a electroluminescence cable which is insulated from the main cord and emit light section by section, in which every electroluminescence cord is controlled by a driver working in synchronization with the main cord to emit light in sequence.
Said current-seen cable is driven to emit light by a multi-group output driver controlled by the program-operated chip. When the main cord is live, the driver works synchronously, then each electroluminescence cord emits and dies light periodically under the control of program-operated chip of the driver, and as each electroluminescent cord is intertwisted helically and people can only see one side of the cable visually, said whole cable is shown as a kind of lighting phenomenon in which a lighting section (or a lighting dot) of said cable goes after another section (or another dot) next to it. The visual direction for going after light is same as the direction of the current flowing in the main cord, so it can indicate the direction of power input and output.
Emitting light of the present invention can be in a variety of forms, is particularly shown as a lighting dynamic phenomenon in which a lighting section goes after another section next to it in sequence and indicate the live state of all kind of main cord such as a power cord, a signal cord. The present invention is particularly used for the power cable connecting the power supply and a general electrical device or household appliance and also for connecting the transmitting unit with the receiving unit in the technical field of computer, telecommunication and communication. The current-seen cable can show a dynamic effect of the live state and input power visually, that means said cable simulate and show the current flow state, we can see whether said cable is live. Additionally, the present invention can widely used in a variety of decoration and illumination fields and also used as a lighting cable in warning sign and fingerpost.
A current-seen cable of the present invention, includes a main cord as a power cord or a signal cord and a plurality of electroluminescence bars or cords, said a plurality of electroluminescence bars or cords are arrayed abreast and are intertwisted helically in sequence to be a electroluminescence cable which is insulated from the main cord and emit light section by section, in which every electroluminescence cord is controlled by a driver working in synchronization with the main cord to emit light in sequence.
The positional relationship between the electroluminescence cable and the main cord can be that the main cord pass through the central axis of the electroluminescence cable or the main cord is arranged lateral to the electroluminescence cable and in parallel to the electroluminescence cable.
The electroluminescence cord of the present invention can be the conventional electroluminescence cord or the electroluminescence cored bar or the electroluminescence cored cord, wherein said electroluminescence cored bar consists of a metal foil base strip with an insulating coating, an electroluminescence powder coating on said insulating coating and a transparent conductive coating on said electroluminescence powder coating. Said the electroluminescence cored cord is formed by removing the auxiliary bare wire on the conductive layer of the conventional electroluminescence cord, the configuration of which is that a base metal cord is coated with insulating medium, an fluorescent powder coating and a transparent conductive layer in sequence.
The several current-seen cables with the different configuration will be as following by using the conventional electroluminescence cord, the electroluminescence cored bar or the electroluminescence cored cord.
In the present invention, in order to enhance the lighting effect of said current-seen cable, the insulation layer of the power cord or signal cord can be made of electroluminescence plastic or light sensitization glisten plastic. As well as at least a strip of electroluminescence plastic or a strip with light sensitization glisten plastic coating is provided on a transparent plastics layer of said current-seen power cable, said strip is in parallel to the power cord and the electroluminescence cable.

There are no shadow or a helical black line on the exposed side of every electroluminescence cored cord because a bare metal wire is arranged on the central axis where electroluminescence cored bar or cord is intertwisted helically. And the cross-section or diameter of the bare metal wire can be equal to or greater than that of the metal base strip so that the difference of resistance between said wire and said strip become less, the effective length of the cable which can emit light section by section in sequence is greater than that of the conventional electroluminescence cord.
In operation, a metal base strip 8 or a metal conductive wire base 9 of the electroluminescence cored bar or cord 1, 2, 3 is connected to a AC output line of each of group 32, 31, 30 output of a plurality of AC drivers 28 via a wire respectively, in other words, a AC output line of group 32 is connected to a metal base strip or cord of the electroluminescence cored bar or cord 1, a AC output line of group 31 is connected to a metal base strip or cord of the electroluminescence cored bar or cord 2, and a AC output line of group 30 is connected to a metal base strip or cord of the electroluminescence cored bar or cord 3, whereas a bare metal wire 5 as a central axis is connected to an other AC output line of each of group 32, 31, 30 output of a plurality of AC drivers 28 and the input power ends of the driver 28 are connected to a live wire 4 and a zero phase line or a ground line 6 of the power in parallel respectively, and a switch 38.
