Description

Technical Field

[0001] This invention relates to the field of flexible linear lights, and more particularly to a flexible linear light that can be bent freely and its manufacturing process. Background Technology

[0002] Flexible linear lights refer to LEDs assembled on a strip-shaped FPC (Flexible Printed Circuit) or PCB (Printed Circuit Board) rigid board, named for their strip-like shape. Due to their long lifespan (typically 80,000 to 100,000 hours), energy efficiency, and environmental friendliness, they are gradually gaining popularity in various industries.

[0003] The prior art discloses a flexible linear light (application number 202220104066.5, application date 2022.01.14). In this technical solution, the bendable direction of the flexible linear light is actually limited by the installation position of the flexible circuit board. In this technical solution, the flexible linear light provided in Embodiment 1 cannot be bent from the side or can only be bent slightly. Therefore, it is necessary to specially design a mold to create a technical solution like Embodiment 2, that is, to place the flexible circuit board on the side of the accommodating space, so that it can be bent from the side, but it still cannot be freely bent. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above problems.

[0005] A flexible linear light that can be bent freely includes: a silicone shell, the interior of which is formed with a receiving space, the receiving space containing: a flexible light-emitting component, including a plurality of interconnected light-emitting units, the plurality of light-emitting units being able to communicate with each other, and notches formed on both sides of the connection between every two light-emitting units to facilitate bending of the flexible light-emitting component from the side; a power supply line, arranged below the flexible light-emitting component along the length direction of the flexible light-emitting component, each light-emitting unit being electrically connected to the power supply line; and an assembly sheet, arranged below the power supply line along the length direction of the power supply line.

[0006] As an improvement to the above technical solution, the light-emitting unit includes: a first flexible circuit board and a plurality of LEDs mounted on the first flexible circuit board. A circuit loop is formed on the first flexible circuit board and electrically connected to the power supply line, and the power supply line supplies power to the circuit.

[0007] As an improvement to the above technical solution, a second flexible circuit board is also included. The two ends of the first flexible circuit board are provided with signal pads for soldering the second flexible circuit board, and two adjacent first flexible circuit boards are connected through the second flexible circuit board.

[0008] As an improvement to the above technical solution, the power supply line is positioned below the notch and offset from the second flexible circuit board.

[0009] As an improvement to the above technical solution, the thickness of the connection between each pair of light-emitting units is thinner than the thickness of the first flexible circuit board, or the thickness of the second flexible circuit board is thinner than the thickness of the first flexible circuit board, so as to allow for bending.

[0010] As an improvement to the above technical solution, the accommodating space is a channel passing through both ends of the silicone shell. The two ends of the silicone shell are provided with openings for communicating channels. An adapter plate is installed on the first flexible circuit board of the light-emitting unit at the end. The adapter cable is also included. The adapter cable passes through the opening and is electrically connected to the adapter plate.

[0011] As an improvement to the above technical solution, the silicone housing includes a light-emitting part and a light-shielding part. The light-emitting part is disposed in the light-shielding part, and the light-shielding part has a light-emitting port on at least one side and exposes the light-emitting part. When powered on, the light of the LED lamp can shine outward through the light-emitting part.

[0012] As one of the improvements to the above technical solution, the thickness of the assembly sheet is less than 0.5 mm.

[0013] A manufacturing process for a flexible linear light that can be bent freely includes the following steps:

[0014] The assembly sheet is placed in a mold for producing the silicone shell, and silicone is extruded into the mold using a silicone extrusion device. After extrusion molding, the silicone shell is dried in a drying device to obtain the silicone shell.

[0015] The LED lights are installed on the first flexible circuit board to form a light-emitting unit, and several light-emitting units are spliced ​​together. An adapter plate is installed on the first flexible circuit board of the light-emitting unit located at the end.

[0016] The power supply line is arranged below the light-emitting unit, and the light-emitting unit is connected to the power supply line;

[0017] The power supply line and the plurality of light-emitting units connected to the power supply line are installed into the silicone housing;

[0018] Insert the adapter cable from the end of the silicone housing into the silicone housing and connect it to the adapter plate;

[0019] End caps are molded at both ends of the silicone shell to seal the silicone shell.

[0020] As an improvement to the above technical solution, during the extrusion molding process, the receiving space is formed inside the silicone shell, and the assembly sheet is disposed within the receiving space.

[0021] Compared with the prior art, the beneficial effects of the present invention are: a notch is formed at the connection between every two light-emitting units to facilitate bending of the flexible light-emitting component from the side; since each light-emitting unit forms a separate circuit loop and is connected to the power supply line, under the premise of normal communication, even if one light-emitting unit fails, it will not affect the normal operation of other light-emitting units, ensuring that other light-emitting units can light up normally; the power supply line and the second flexible circuit board are staggered, on the one hand to avoid the stacking of electronic components affecting heat dissipation, and on the other hand to avoid the power supply line and the second flexible circuit board from interfering with each other.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-6 In this embodiment of the invention, a flexible linear light that can be bent freely includes: a silicone shell 1, the silicone shell 1 having an internally formed receiving space 13, the receiving space 13 containing: a flexible light-emitting component, the flexible light-emitting component including a plurality of interconnected light-emitting units 2, the plurality of light-emitting units 2 being able to communicate with each other, and a notch 231 being formed on both sides of the connection 23 between every two light-emitting units 2 to facilitate bending of the flexible light-emitting component from the side; a power supply line 3, the power supply line 3 being arranged below the flexible light-emitting component along the length direction of the flexible light-emitting component, each light-emitting unit 2 being electrically connected to the power supply line 3; and an assembly sheet 4, the assembly sheet 4 being made of PET or PC material, and being arranged below the power supply line 3 along the length direction of the power supply line 3, preferably, the thickness of the assembly sheet 4 being less than 0.5 mm.

[0033] Furthermore, the light-emitting unit 2 includes: a first flexible circuit board 21 and a plurality of LED lights 22 mounted on the first flexible circuit board 21. A circuit loop is formed on the first flexible circuit board 21 and electrically connected to the power supply line 3, and the power supply line 3 supplies power to the first flexible circuit board 21.

[0034] Furthermore, it also includes a second flexible circuit board 24. The first flexible circuit board 21 has signal pads at both ends for soldering the second flexible circuit board 24. Specifically, the first flexible circuit board 21 has signal pads at both ends away from the side where the LED lamp 22 is installed. Two adjacent first flexible circuit boards 21 are connected through the second flexible circuit board 24. That is, one end of the second flexible circuit board 24 is soldered to the signal pad of the first flexible circuit board 21 on one side, and the other end of the second flexible circuit board 24 is soldered to the signal pad of the first flexible circuit board 21 on the other side.

[0035] Furthermore, the power supply line 3 is positioned below the notch 231 and offset from the second flexible circuit board 24. This design serves two purposes: firstly, to avoid the stacking of electronic components affecting heat dissipation, and secondly, to prevent the energized power supply line 3 from interfering with the second flexible circuit board 24.

[0036] In one embodiment, when manufacturing the light-emitting unit 2 (or the first flexible circuit board 21), several light-emitting units 2 (or the first flexible circuit board 21) are connected together, and the connection 23 between every two light-emitting units 2 (or the first flexible circuit board 21) is made thin. At the same time, the two sides of the connection 23 are narrowed to form a notch 231. The connection 23 is routed and connected to the two light-emitting units 2 (or the first flexible circuit board 21) on both sides, thereby realizing the communication connection between the light-emitting units 2.

[0037] In another embodiment, when manufacturing the light-emitting unit 2 (or the first flexible circuit board 21), several light-emitting units 2 (or the first flexible circuit board 21) are not connected to each other, but are connected by a second flexible circuit board 24. The width of the second flexible circuit board 24 is narrower than the width of the first flexible circuit board 21, and the thickness of the second flexible circuit board 24 is thinner than the thickness of the first flexible circuit board 21 so as to bend.

[0038] The two embodiments described above can be selected based on the manufacturer's or supplier's circuit board manufacturing capabilities;

[0039] It should be noted that the power supply line 3 is not only used to supply power to each of the first flexible circuit boards 21, but also to further strengthen the connection between each of the first flexible circuit boards 21. When bending, it no longer relies solely on the connection point 23 or the second flexible circuit board 24 between the first flexible circuit boards 21. With the support of the power supply line 3, it will be more durable, and the external power supply line 3 can also improve the load-bearing capacity.

[0040] As an improvement to the above technical solution, the accommodating space 13 is a channel passing through both ends of the silicone shell 1. The two ends of the silicone shell 1 are provided with openings for communicating channels. An adapter plate 7 is installed on the first flexible circuit board 21 of the light-emitting unit 2 at the end, and an adapter cable 6 is also included. The adapter cable 6 passes through the opening and is electrically connected to the adapter plate 7.

[0041] As an improvement to the above technical solution, the silicone housing 1 includes a light-emitting part 11 and a light-shielding part 12. The light-emitting part 11 is disposed in the light-shielding part 12. The light-shielding part 12 has a light-emitting port on at least one side and exposes the light-emitting part 11. The material of the light-emitting part 11 includes light-emitting adhesive, while the material of the light-shielding part 12 includes white silicone. The process is to use extrusion molding to form the receiving space 13 between the light-emitting part 11 and the light-shielding part 12. When powered on, the light of the LED lamp 22 can shine outward through the light-emitting part 11.

[0042] A manufacturing process for a flexible linear light that can be bent freely includes the following steps:

[0043] The assembly sheet 4 is placed in the mold for producing the silicone shell 1. Silicone is extruded into the mold using a silicone extrusion device. During the extrusion molding process, the receiving space 13 is formed inside the silicone shell 1. The assembly sheet 4 is placed in the receiving space 13. After extrusion molding, the silicone shell 1 is dried in a drying device to obtain the silicone shell 1.

[0044] The LED lights 22 are installed on the first flexible circuit board 21 to form a light-emitting unit 2. Several light-emitting units 2 are spliced ​​together (in one embodiment above, if several light-emitting units 2 (or the first flexible circuit board 21) are already connected together when the light-emitting unit 2 (or the first flexible circuit board 21) is manufactured, the splicing step can be omitted). An adapter plate 7 is also required to be installed on the first flexible circuit board 21 of the light-emitting unit 2 at the end.

[0045] The power supply line 3 is arranged below the light-emitting unit 2, and the light-emitting unit 2 is connected to the power supply line 3. Since the first flexible circuit board 21 of each light-emitting unit 2 forms a circuit loop, each light-emitting unit 2 is electrically connected to the power supply line 3.

[0046] The power supply line 3 and several light-emitting units 2 connected to the power supply line 3 are installed into the receiving space 13 of the silicone shell 1. At this time, the power supply line 3 is on the assembly sheet 4.

[0047] Insert the adapter cable 6 through the end opening of the silicone housing 1 into the silicone housing 1 and connect it to the adapter plate 7;

[0048] End caps 5 are molded at both ends of the silicone shell 1, and the end caps 5 seal the silicone shell 1, that is, the end caps 5 simultaneously seal the accommodating space 13 and the opening.

[0049] It is worth mentioning that the mounting sheet 4 facilitates the installation of the power supply line 3 and the several light-emitting units 2 connected to the power supply line 3. It is understandable that the first flexible circuit board 21 and the second flexible circuit board 24 have excellent characteristics such as light weight, thin thickness, and free bending and folding. They are also relatively flexible. Since the silicone shell 1 is made of silicone, even the first flexible circuit board 21 connected to the power supply line 3 will be difficult to install when installed in the accommodating space 13 due to surface friction. Secondly, the size of the accommodating space 13 is relatively limited. Therefore, the mounting sheet 4 is needed to cooperate with the first flexible circuit board 21 and the power supply line 3 for installation. In order not to affect bending from the side, the thickness of the mounting sheet 4 should be controlled to be less than 0.5mm.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
