This patent application claims the benefit and priority of Chinese Patent Application No. 2023108430740 filed with the China National Intellectual Property Administration on Jul. 10, 2023, the disclosure of which is incorporated by reference herein in its entirety as part of the present application
The present disclosure relates to the technical field of cables, in particular to a cable containing an LED (Light Emitting Diode) light strip driven by an induced current.
In some special environments, such as open-pit coal mines, cables are often dragged and moved while being paved on the ground without good protection, and follow the movement of electric shovels and other equipment. There are many engineering vehicles for transporting coal around the electric shovels. At night or in dark environment, because site operators cannot see the cables, the cables are often crushed by the engineering vehicles, resulting in cable damage, shortened cable service life and greatly increased use cost. In a traditional cable containing an LED light strip, an electric cabinet needs to be externally connected to a low-voltage direct-current power supply so as to lighten the LED light strip. However, in general open-pit coal mines and other occasions, the voltage of the electric cabinet is often unsuitable for the LED light strip, resulting in the abandonment of the visual function in the traditional cable containing an LED light strip to cause the waste.
The present disclosure aims to provide a cable containing an LED light strip driven by an induced current to solve the problems in the prior art. A coil block generates an induced potential through an alternating magnetic field generated after a power wire core is powered on, and the LED light strip is driven by the induced potential, so that the LED light strip can be lightened without an additional power supply. The construction is simple and convenient, so that the cable can have a visual function at night, thereby ensuring that the cable is not crushed in the operational process, and the safe use of the cable is guaranteed.
In order to achieve the purpose, the present disclosure provides the following scheme.

After the cable is powered on, an alternating current passes through the power wire core 3, and a vortex alternating magnetic field is formed around the power wire core 3. The coil block 11 near the power wire core 3 generates the induced potential under the action of the alternating magnetic field. The induced current is generated in the closed loop 10 through the induced potential. The LED chip 12 is lightened by the induced current, so that the LED light strip 1 can be lightened without an additional power supply.

In some embodiments, the insulation layer 32 is covered with a nonmetal shielding layer 34 and a metal shielding layer 35 in sequence.
The power wire core 3 can only include a power wire core conductor 31 and an insulation layer 32, or besides a power wire core conductor 31 and an insulation layer 32, additionally include one, two or three of a power wire core conductor shielding layer 33 (nonmetal material), a nonmetal shielding layer 34 and a metal shielding layer 35.
In some embodiments, the LED light strip 1 further includes a light-strip protecting layer 13 covering the coil block 11 and the LED light chip 12, and the light-strip protecting layer 13 is made of a light-transmitting material. The coil block 11 includes a plurality of coils 111 connected in series. When the induced potential of one coil 111 is insufficient to lighten the LED light chip 12, a plurality of coils 111 may be connected in series to enhance the induced potential so as to lighten the LED chip 12 (shown in
In some embodiments, the LED light strip 1 includes a plurality of independent closed loops 10. When one closed loop 10 is provided, the closed loop 10 is arranged along the length direction of the LED light strip 1. When two or more than two closed loops 10 are provided, the closed loops 10 are arranged in sequence along the length direction of the LED light strip 1. Since a plurality of independent working units (closed loops 10) can be used, the problem that the whole cable cannot emit light due to the fact that the cable is cut off in the using process is avoided.
When in use, a plurality of independent closed loops 10 can be canned in a transparent tube to form an LED light strip 1, and the LED light strip 1 is placed beside any power wire core 3 or in a gap between any two power wire cores 3 as a light emitting unit so that the cable emits light.
In some embodiments, the LED light strip 1 is a single-sided LED light strip or a double-sided LED light strip, and it is only necessary to ensure that a light-emitting surface of the single-sided LED chip 12 faces outward. At least one LED light strip 1 is provided, and can be arranged at any position around the cable core. The LED light strip 1 is a light strip with a single light-emitting color or a light strip with a plurality of light-emitting colors for increasing the visual effect of the cable and high-lighting the cable. The shape of the LED light strip 1 is a circle, a rectangle, an oval, a triangle and a trapezoid, but is not limited to the above shapes.
In some embodiments, the cable core further includes a ground wire core 4 and a grounding detection wire core 5. The grounding detection wire core 5 includes a detection wire core conductor 51 and a detection wire core insulation layer 52 covering the detection wire core conductor 51.

The three power wire cores 3 are mutually attached in pair and form three gaps on the outer side, and the LED light strip 1, the ground wire core 4 and the grounding detection wire core 5 are respectively arranged in the three gaps and attached with the three power wire cores 3, ensuring that the LED light strip 1, the three power wire cores 3, the ground wire core 4 and the grounding detection wire core 5 is stably operated in the respective working processes. The LED light strip 1 is closely attached to the outer layer of the power wire core 3, and the efficiency of generating the induced current can be improved, and so that the performance of the LED cable is guaranteed.
In some embodiments, the cable core further includes a control wire core and an optical fiber unit. At the moment, the ground wire core 4 and the grounding detection wire core 5 may not be arranged, or the ground wire core 4 and the grounding detection wire core 5 is replaced by a control wire core and an optical fiber unit.
In some embodiment, the outer protection layer 2 is made of a transparent or semitransparent polymer material, and the light-strip protecting layer 13 is made of a transparent or semitransparent polymer material. The visualization of the LED light strip 1 is ensured, and the visualization effect of the cable is increased.
