Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, and in particular to a flexible circuit board with LED lights. Background Technology

[0002] There is an existing Chinese invention patent published on May 22, 2020, with publication number CN111192948A, which describes an LED dispensing method that increases the adhesion of LEDs. The process is simple and the product yield is high. It can be used as a backlight for narrow bezel backlight modules.

[0003] However, because the circuit board is flexible and can be bent, and the LED is only supported by the insulating glue in the middle and the printed solder paste at both ends, the insulating glue effectively avoids electrical interference between adjacent conductive paths. However, the amount of glue applied is difficult to control. When the height of the insulating glue between the two leads of the LED is higher than the height of the printed solder paste, the LED will experience a situation where the other lead lifts up when one lead is under force, resulting in a seesaw phenomenon, which ultimately leads to an open circuit in the LED. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flexible circuit board with LED lights to solve the problem that when the height of the insulating glue between the two leads of the LED light is higher than the height of the printed solder paste, the LED light will cause one lead to be stressed while the other lead is lifted, resulting in a seesaw phenomenon and ultimately causing the LED light to break the circuit.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible circuit board with LED lights, comprising a flexible circuit board body, an insulating layer coated on the flexible circuit board body, at least one set of mounting areas on the insulating layer, each mounting area including two clearance slots that are not connected to each other, a conductive element on the flexible circuit board body, the conductive element being located within the clearance slot, the top surfaces of the two conductive elements being electrically connected to LED lights, and the thickness of the insulating layer being less than the thickness of the conductive element.

[0006] Preferably, conductive adhesive is provided between the LED light and the conductive component.

[0007] Preferably, the top surface of the flexible circuit board body is provided with a plurality of potting components, which encapsulate the LED light.

[0008] Preferably, the insulating layer is insulating oil, and the thickness of the insulating oil is 0.016mm-0.024mm.

[0009] Preferably, the conductive element is a silver paste block or silver paste block, and the thickness of the conductive element is 0.11mm-0.18mm.

[0010] Preferably, the potting compound is made of a light-transmitting material.

[0011] Preferably, the two clearance slots in a set of installation areas are arranged in a straight line or a wavy shape on the opposite sidewalls.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0013] This invention, through the design of the insulating layer, not only facilitates installation but also effectively avoids electrical interference between adjacent conductive paths. Furthermore, it prevents the uncontrollable application of insulating adhesive, which can lead to a situation where the height of the insulating adhesive between the two LED leads exceeds the height of the printed solder paste. This can cause the LED to tilt upwards when one lead is under pressure, resulting in a seesaw effect. Therefore, this invention effectively prevents open circuits in the LED.

[0015] Figure 2 This is a schematic diagram of the flexible circuit board body, insulating layer, conductive components, void groove, and LED lamp structure of this utility model;

[0016] The components include: 1. Flexible circuit board body; 2. Insulating layer; 21. Hollow groove; 3. Conductive component; 4. LED light; 5. Encapsulation component. Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0018] like Figure 2 As shown, this utility model provides a flexible circuit board with LED lights, including a flexible circuit board body 1, an insulating layer 2 coated on the flexible circuit board body 1, at least one set of mounting areas on the insulating layer 2, the mounting areas including two clearance grooves 21, the two clearance grooves 21 are not connected to each other, a conductive element 3 is provided on the flexible circuit board body 1, the conductive element 3 is located in the clearance groove 21, the top surface of the two conductive elements 3 is electrically connected to the LED lights 4, and the thickness of the insulating layer 2 is less than the thickness of the conductive element 3.

[0019] The insulation layer 2, with its design, not only facilitates installation but also effectively avoids electrical interference between adjacent conductive paths. It also prevents the problem of uncontrollable glue application, which can lead to a situation where the height of the insulating glue between the two pins of the LED 4 exceeds the height of the printed solder paste. This can cause the LED 4 to tilt when one pin is under pressure, resulting in a seesaw effect. This effectively prevents the LED 4 from experiencing an open circuit.

[0020] Conductive adhesive (not shown in the figure) is provided between LED light 4 and conductive component 3. It serves to connect and solder the circuit pins of LED light 4 and conductive component 3, ensuring normal electrical conduction between LED light 4 and conductive component 3.

[0021] like Figure 1 and Figure 2 As shown, the top surface of the flexible circuit board body 1 is provided with several potting components 5, which encapsulate the LED light 4. By setting the potting components 5, the resistance to external impact and vibration can be improved.

[0022] The insulating layer 2 is made of insulating oil, ensuring that its thickness is not too thick, thus ensuring that its thickness is less than that of the conductive component 3, and facilitating its installation, avoiding the trouble of applying insulating adhesive. The thickness of the insulating oil is 0.016mm-0.024mm. By setting such a thickness of insulating oil, it can ensure that the insulating oil plays a good role in isolating and preventing short circuits between the two conductive components 3, while also avoiding the waste of material caused by laying it too thickly (greater than 0.024mm). When the thickness is less than 0.016mm, it is not possible to effectively prevent short circuits between the two conductive components 3.

[0023] like Figure 2 As shown, the conductive component 3 is a silver paste block or silver paste block, which serves as the pin of the circuit to electrically connect to the LED lamp 4. The thickness of the conductive component 3 is 0.11mm-0.18mm. When the thickness of the conductive component 3 is less than 0.11mm, the conductivity is poor. When the thickness of the conductive component 3 is greater than 0.18mm, it will result in material waste.

[0024] like Figure 1 As shown, the potting compound 5 is made of a light-transmitting material, preferably a transparent material, which not only ensures that the light emitted by the LED lamp 4 can be observed, but also that the specific usage of the LED lamp 4 can be observed.

[0025] like Figure 2 As shown in the figure, actual testing showed that when the shape is arc-shaped, it may cause a short circuit between the two conductive parts 3. The two clearance grooves 21 in a set of installation areas are set to straight or wavy shapes on the side walls to reduce the probability of a short circuit between the two conductive parts 3.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
