Description

A luminous cable

Technical field

The invention relates to a cable, in particular to a luminous cable.

This application requires the Chinese patent application filed on May 23, 2019 with the application number CN201920751423.5 and the application number filed on July 12, 2019 as Priority of the Chinese patent application of CN201921089709.8.

Background technique

A light-emitting cable is a wire that can emit light. This is a wire based on flip-chip LED chips. It generally includes a flip-chip LED chip and two copper wires. The flip-chip LED chip is connected to two copper wires. When wires or two or more copper wires are connected in series or in parallel with positive and negative electrodes, the flip-chip LED chip emits light.

The principle of the above-mentioned light-emitting cable is very simple, and it is no different from the simplest light-emitting circuit, but as a wire, what we are concerned about is not its circuit principle, but the radial size, toughness, and tensile performance of this wire. , Flexibility, stretchability, and whether it can emit light at 360 degrees, etc. If this light-emitting cable can be made as thick as the yarn, and has high toughness and strong tensile strength, then this light-emitting cable It will be widely used in accessories, apparel, furniture, daily necessities, electronic wearable devices and smart textiles, and the market prospect is quite broad.

However, because the luminous cable is currently in the research and development stage, the technology is not mature enough and there are many defects, so it is difficult to apply and market the product.

Currently there are two main structures of luminous cables:

(1) Two enameled copper wires bonded side by side are used as the wires of the LED optical fiber, and each flip-chip LED chip is welded to the two enameled copper wires respectively. This kind of light-emitting cable meets the requirements of small radial size, but its toughness and tensile performance depend on two enameled copper wires, and as LEDs develop towards mini LEDs and micro LEDs, flip-chip LED chips have also changed smaller. The diameter of the two enameled wires bonded side by side is reduced to fit the LED flip chip pads, and then lacks tensile performance and is easy to break. Generally, the use of LED fiber optic wires will be affected by their bending radius, tensile strength and fiber buckling. For example, thin wires are more flexible but not as rigid as thick wires, and are more often used in electronic wearable devices.

The light-emitting cable with the above structure can only be applied to the product by pasting, and the product is not allowed to deform, such as bending, rubbing, washing, etc.

(2) Two bare copper wires are arranged side by side with a gap, and each flip-chip LED chip is soldered on the two bare copper wires respectively, and then the two bare copper wires and the flip-chip LEDs on them are covered by a transparent insulating material The chip is wrapped to form a wire, and the transparent insulating material is filled between two bare copper wires. The outer covering of the transparent insulating material is generally formed by an injection molding process. As a result, the outer covering of the transparent insulating material is generally thicker, and only thicker can be obtained. High toughness, strong tensile strength, but this makes it difficult for this kind of light-emitting cable to be widely used in accessories, clothing, furniture, electronic products, and daily necessities, because the light-emitting cable with a larger radial size is pasted on the product Later, the appearance of the product is destroyed, which is unacceptable. Therefore, the light-emitting cable with this structure cannot be promoted and applied on the product.

In some published patent application documents, those skilled in the art have made efforts to combine micro LEDs with wires. For example, the US patent document with application number US10325885B2 discloses various ways to transfer micro LEDs to wires. When a number of LEDs are distributed along the length of a pair of wires, the method disclosed in the patent application can be used to accurately install and position the LEDs. However, this method still cannot overcome the above-mentioned toughness and tensile properties. Technical problems such as insufficient.

Another patent document with application number WO2016038342A1 discloses an electronic functional yarn. The structure is a carrier core wire provided with chips along its own axis. In the present invention, the wire and the carrier core wire are on different axes, so that the user's pulling force is transferred away from the carrier core wire where the chip is located. The carrier core wire in WO2016038342A1 lacks stretchability or uses elasticity.

Example 1:

Referring to FIGS. 1-3, this embodiment provides a light-emitting cable, which includes a light-emitting wire 1 and a base line 2, and the light-emitting wire 1 is spirally wrapped tightly outside the base line 2.

As shown in Figure 2, the baseline 2 is composed of multiple filaments 201; as shown in Figure 3, the luminous wire 1 includes two enameled copper wires 101 and a plurality of flip-chip LED chips 102, and the two enameled copper wires 101 are side by side And bonded together, each flip-chip LED chip 102 is soldered on the corresponding two enameled copper wires 101 respectively, and the enameled layer 103 on the enameled copper wire 101 constitutes the insulation isolation between the two enameled copper wires 101. Among them, the flip chip 102 may be an ultraviolet LED flip chip or an infrared LED flip chip.

In other embodiments, the above-mentioned flip-chip LED chip 102 may be a photodiode, a system packaged LED (SIP with LED), a miniature COB/COF packaged LED (miniature COB/COF LED package), and an addressable integrated LED driver (Addressable LED At least one of driver integrated LED and LED as sensors, where the LED sensor may be a temperature sensor, a heart rate sensor, or other sensors.

Since the light-emitting cable is composed of the light-emitting wire 1 spirally wrapped around the base line 2, the toughness and tensile performance of the light-emitting cable are mainly borne by the base line 2. The base line 2 uses the fiber yarn 201 with small diameter and high tensile performance. Make the light-emitting cable have higher toughness and better tensile performance; and the radial size of the light-emitting cable depends on the diameter of the base line 2 and the diameter of the light-emitting wire 1, multiple (usually 2-7) fiber filaments The diameter of the base line 2 formed by 201 is very small, and the enameled copper wire 101 in the light-emitting wire 1 only needs to meet its electrical conductivity. The radial dimension of the light-emitting wire 1 can also be set very small, and no protective glue is required. Layers and so on. Therefore, the radial size of the light-emitting cable can be set very small, and the light-emitting cable surrounds the baseline 2 360 degrees, so it can emit 360-degree light around, which can meet the requirements of accessories, clothing, furniture, electronic products, daily necessities, etc. Application requirements.

The number of enameled copper wires 101 in the light-emitting wire 1 can be two, three or four. In the case of two enameled copper wires 101, one of the enameled copper wires 101 is connected to the positive electrode of the power supply, and the other An enameled copper wire 101 is connected to the negative pole of the power supply; when the number of enameled copper wires 101 is three or more, the wiring method is more flexible. It can be connected in parallel or in series, or mixed in parallel and series, and can be set to change. Way of luminescence.

The above-mentioned multiple fiber filaments 201 constitute the base line 2, and each of the fiber filaments 201 may be directly close together and bonded together, or may be entangled with each other to form a strand. The material of the baseline 2 can also be at least one of nylon, polyester resin, carbon fiber, Kevlar fiber, silica gel, rubber, and plastic, or a composite material of the foregoing materials. When the thread of the above-mentioned material is used, the base line 2 also has good bendability and shape recovery. It can be bent arbitrarily under the action of external force, and can be restored to its original shape when the external force is removed. In particular, when using certain materials of thread, the base line 2 can also have good elasticity and stretchability in the axial direction. For example, using monofilament spandex, Lycra (22 dtex) or nylon as the base line 2 material. When using some materials of silk thread, the base line 2 has radial compressibility, for example, polyester yarn is used as the base line 2. Both the axial elasticity and radial compressibility will make the light-emitting cable stretchable, and the light-emitting wire 1 can be similar to a stretchable telephone spiral.

In other embodiments, the middle copper wire of the enameled copper wire 101 can be replaced with other conductive metal conductors, such as bare copper wire, bare silver wire, etc., as long as there is insulation between the two; It can also be replaced with carbon fiber, generally using multiple strands of carbon fiber; or replaced with graphene or carbon nanotubes. In other embodiments, a combination of a conductive metal conductor, carbon fiber, graphene or carbon nanotube and an insulating wire may also be used.

In addition to the enameled wire, in other embodiments, a flat flexible cable (FFC, flat flexible cable) or a flexible circuit board ( FPC (Flexible Printed Circuit) is electrically connected to the flip-chip LED chip 102.

When using, for example, a flexible circuit board as the conductive member, this embodiment also overcomes the technical problem of the limitation of the plane freedom. Generally speaking, when the FPC is laid flat, it can only be crimped and bent in the space, and cannot be bent on the plane where it is laid. If the FPC is spirally wound on the baseline 2, it will be for the entire light-emitting cable , It can be bent in any direction along the radial direction, and there is no limited dimension of the degree of freedom on the plane, which is said to overcome the limit of the degree of freedom of the plane in this embodiment.

In other embodiments, the base line 2 uses a stainless steel wire. The use of stainless steel wire as the base line 2 has higher strength and tensile performance. Since the enameled copper wire 101 itself is insulated on the surface, there is no short circuit problem when the stainless steel wire is used as the base line 2. It should be noted that if the base line 2 uses stainless steel wire, the light-emitting cable does not have shape recoverability.
