Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1 to 7The first embodiment of this utility model proposes a long cascaded light strip, which includes: one or more light strip bodies 10 and conductive components 20; each light strip body 10 includes a lamp housing 11, a silicone layer 12, a cascaded strip 13, a connecting component 14, and a lamp board 15;

[0039] The silicone layer 12 and the lamp panel 15 are stacked and both are disposed within the lamp housing 11; the silicone layer 12 is provided with a perforated hole 121 and a connecting hole 122, the connecting hole 122 communicates with the perforated hole 121, the cascade belt 13 is disposed within the perforated hole 121, and the connecting belt assembly 14 passes through the connecting hole 122 and connects the cascade belt 13 and the lamp panel 15 respectively;

[0040] The ends of the conductive assembly 20 are respectively connected to the cascaded strips 13 of the adjacent light strip bodies 10.

[0041] In some embodiments, the connection between a light strip body 10 and an external wire 30 is achieved through the connecting component 20, enabling the independent operation of any light strip body 10.

[0042] In other embodiments, the connecting component 20 and the light strip body 10 are alternately arranged. The first connecting component 20 connects the external wire 30 to the light strip body 10. The second and subsequent connecting components 20 connect two adjacent light strip bodies 10 respectively. The last connecting component 20 connects the last light strip body 10 and the external wire 30. Alternatively, the last connecting component 20 may only block the outer end of the last light strip body 10.

[0043] In some other embodiments, the connecting assembly 20 is connected to three or more adjacent LED strip bodies 10.

[0044] In the embodiments of this utility model, the guide component 20 allows users to change the overall length of the light strip by changing the number of guide components 20 and light strip body 10 used; the long cascaded light strip of this utility model can achieve both short-distance lighting and long-distance continuous lighting.

[0045] The silicone layer 12 is used to wrap the cascaded strip 13, which avoids damage to the cascaded strip 13 due to bending when the long cascaded light strip is bent, and prevents damage to the cascaded strip 13 from affecting the connection stability between the light board 15 and the cascaded strip 13. The silicone layer 12 also acts as a buffer to protect the light board 15 and prevent damage to the light board 15 due to bending operations, further ensuring the structural stability and electrical connection reliability of the light strip and improving the service life of the long cascaded light strip.

[0046] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figure 6Each of the light strip bodies 10 includes two or more light boards 15; each light board 15 includes a board body 151, a solder strip 152 and cascaded solder pads 153;

[0047] The welding strip reel 152 is disposed on one side of the plate body 151, and the tape receiving assembly 14 connects the welding strip reel 152 and the cascade tape 13 respectively;

[0048] The two ends of the main body 151 are respectively provided with the cascaded solder pads 153, and the cascaded solder pads 153 of two adjacent lamp boards 15 are connected to each other.

[0049] In this embodiment, a stable connection between the strip assembly 14 and the lamp board 15 is achieved through the solder strip tray 152, ensuring smooth transmission of current and signals, and facilitating the electrical connection between the lamp strip body 10 and the conductive assembly 20. The cascaded solder pads 153 provided at both ends of the board body 151 facilitate quick connection between adjacent lamp boards 15.

[0050] By setting two or more light boards 15 in each light strip body 10 and using cascaded pads 153 to connect adjacent light boards 15, the light strip board in each light strip body 10 is divided into multiple light boards 15, which makes it easy to change the length of each light strip body 10 as needed. Moreover, when a light board 15 has a problem, it can be quickly located and replaced without replacing the entire light strip body 10, thereby reducing maintenance costs and time. For example, when a light board 15 fails, the light strip body 10 in the faulty area can be cut off to form two new light strip bodies 10. Then, the cascaded strips 13 of the two new light strip bodies 10 are connected by the connecting components 20, thereby realizing the electrical connection of the two new light strip bodies 10.

[0051] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figures 2 to 4 The cascaded tape 13 includes a positive electrode tape 1301 and a negative electrode tape 1302. The tape hole 121 includes a first split hole 1211 and a second split hole 1212. The tape connector assembly 14 includes a first tape connector 141 and a second tape connector 142. The solder tape reel 152 includes a positive electrode reel 1521 and a negative electrode reel 1522. The positive electrode reel 1521 and the negative electrode reel 1522 are respectively disposed on the two sides of the plate body 151.

[0052] The positive electrode strip 1301 is disposed in the first dividing hole 1211, and the negative electrode strip 1302 is disposed in the second dividing hole 1212. The positive electrode strip 1301, the first connecting member 141 and the positive electrode disk 1521 are connected in sequence, and the negative electrode strip 1302, the second connecting member 142 and the negative electrode disk 1522 are connected in sequence.

[0053] In this embodiment, the positive electrode strip 1301 and the negative electrode strip 1302 are respectively disposed in the first dividing hole 1211 and the second dividing hole 1212, and are connected to the positive electrode tray 1521 and the negative electrode tray 1522 on the welding strip tray 152 by the first connecting member 141 and the second connecting member 142, respectively. This achieves independent transmission of current and signal, avoids interference between the positive and negative electrodes, and improves the electrical performance of the lamp strip. At the same time, it also makes the connection of the lamp strip clearer and easier to maintain. When a fault occurs, the specific problem point can be quickly located and repaired. In addition, the positive electrode tray 1521 and the negative electrode tray 1522 are respectively disposed on the two sides of the plate body 151, so that the positive electrode strip 1301 and the negative electrode strip 1302 are located on the two sides of the plate body 151, which helps to reduce the size of the lamp housing 11 and also helps to ensure the welding stability of the plate body 151 with the positive electrode strip 1301 and the negative electrode strip 1302 respectively.

[0054] The first connector 141 and the second connector 142 of the connector assembly 14 are both solder blocks formed by melting solder wire.

[0055] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figures 2 to 5 Both the positive electrode strip 1301 and the negative electrode strip 1302 include a core wire 131, and the core wire 131 includes at least two branch wires 1311, which are intertwined and connected to each other.

[0056] In this embodiment, the core wire 131 is used to ensure stable welding between the cascade strip 13 and the lamp board 15, and also to improve the flexibility of the lamp strip, so that the cascade strip 13 can adapt to bending at different angles.

[0057] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figure 5 The dividing line 1311 includes a copper core layer 13111 and a tin core layer 13112, with the tin core layer 13112 wrapping around the outside of the copper core layer 13111.

[0058] In this embodiment, the copper core layer 13111 is wrapped with a tin core layer 13112, which enhances the conductivity of the branch line 1311, improves the corrosion resistance of the branch line 1311, and extends the service life of the cascade belt 13.

[0059] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figure 6 The plate body 151 has a bending groove 1511 on one or both sides, and the bending groove 1511 includes two or more sub-grooves, which are spaced apart from each other.

[0060] In this embodiment, when the plate body 151 is bent, the bending point falls at the bending groove 1511, so as to avoid the stress generated during bending from accumulating at the bending point and causing the bending point to break or be damaged.

[0061] When the light strip body 10 is bent from the front to the side, the bending point falls on the groove on one side of the plate body 151. At this time, the two sides of the plate body 151 on both sides of the groove are close to each other, and the other sides of the plate body 151 are far apart.

[0062] When the light strip body 10 is bent in the opposite direction, the bending point falls on the groove on the other side of the plate body 151. At this time, the other sides of the plate body 151 on both sides of the groove are close to each other, and the one side of the plate body 151 is far away from each other.

[0063] In some embodiments, a bending groove 1511 is provided on one side of the plate body 151.

[0064] In some other embodiments, the two sides of the main plate 151 are provided with bending grooves 1511, and the grooves on the two sides of the main plate 151 are arranged opposite to each other. When the light strip body 10 is bent, the grooves on the two sides of the main plate 151 are used to diffuse the stress on the two sides of the main plate 151 at the bending point (the compressive stress on the side of the plate where the bending point is located and the tensile stress on the side of the plate opposite the bending point).

[0065] In some other embodiments, the two sides of the plate body 151 are provided with bending grooves 1511, and the grooves on the two sides of the plate body 151 are alternately arranged.

[0066] The bending groove 1511 on each side consists of two or more slots spaced apart from each other. By increasing the number of slots, the bending points of the light strip body 10 are increased. This allows users to freely adjust the bending angle and shape of the light strip as needed to meet the lighting requirements of different scenarios.

[0067] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figure 6 The plate body 151 has a transition side wall 1512 and a first groove wall 1513 and a second groove wall 1514 that surround and form the groove on one side of the plate body 151. The first groove wall 1513 and the transition side wall 1512 are alternately arranged, and the second groove wall 1514 is connected to the first groove wall 1513 and the transition side wall 1512 respectively; the welding strip 152 is provided on the second groove wall 1514.

[0068] In this embodiment, when a forward lateral bend is required, the bend point falls on the first groove wall 1513, and the second groove walls 1514 on both sides of the first groove wall 1513 are close to each other; when a reverse lateral bend is required, the bend point falls on the side of the plate body 151 opposite to the first groove wall 1513 (or the opposite grooved first groove wall 1513), and the second groove walls 1514 on both sides of the first groove wall 1513 are far apart from each other; by using the welding strip 152 provided on the second groove wall 1514, the space occupied by the plate body 151 is reduced.

[0069] In other embodiments, the solder strip 152 is disposed on the transition sidewall 1512.

[0070] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figures 2 to 4 The lamp housing 11 is also provided with a first lamp slot 111, a second lamp slot 112 and a third lamp slot 113;

[0071] The first lamp slot 111, the second lamp slot 112 and the third lamp slot 113 are arranged sequentially along the direction close to the light-emitting surface of the lamp housing 11. The silicone layer 12 and the lamp plate 15 are disposed in the first lamp slot 111, and the third lamp slot 113 is in an empty state.

[0072] The lamp panel 15 also includes lamp beads 154, which are disposed on the panel body 151; the first lamp groove 111 is connected to the second lamp groove 112 to make room for the placement of the lamp beads 154.

[0073] In this embodiment, the first lamp groove 111 is used to limit the placement of the silicone layer 12, the cascaded strip 13 within the silicone layer 12, and the lamp board 15; the second lamp groove 112 is used to avoid the placement of the lamp beads 154 on the lamp board 15, so as to prevent the lamp housing 11 from interfering with the lamp beads 154 during the bending operation; and the third lamp groove 113 is used to reduce the overall hardness of the lamp strip body 10, so as to facilitate the bending of the lamp strip body 10.

[0074] Specifically, the lamp housing 11 also has a third groove wall 114 that encloses and forms a second lamp groove 112. The side opening of the second lamp groove 112 connects to the first lamp groove 111. The third groove wall 114 is arc-shaped, and the distance from the middle of the third groove wall 114 to the lamp bead 154 is greater than the distance from both ends of the third groove wall 114 to the lamp bead 154. This design avoids obstructing the placement of the lamp bead 154 while facilitating the diffused light emission of the lamp bead 154.

[0075] The lamp housing 11 is also provided with a fourth groove wall 115, a fifth groove wall 116, a sixth groove wall 117 and a seventh groove wall 118 that surround and form a third lamp groove 113. The fourth groove wall 115, the fifth groove wall 116, the sixth groove wall 117 and the seventh groove wall 118 are connected in sequence. The fourth groove wall 115 is arc-shaped. The distance from the middle of the fourth groove wall 115 to the lamp bead 154 is greater than the distance from the two ends of the fourth groove wall 115 to the lamp bead 154, so as to facilitate the diffused light emission of the lamp bead 154.

[0076] The sixth groove wall 117 is arc-shaped, and the distance from both ends of the sixth groove wall 117 to the lamp bead 154 is greater than the distance from the middle of the sixth groove wall 117 to the lamp bead 154.

[0077] When the light strip body 10 is bent in the forward direction, the plate surfaces on both sides of the bending point of the light plate 15 (the plate surface on the side with the light beads 154) move closer to each other. By utilizing the setting of the sixth groove wall 117, the bending stress is diffused to the third light groove 113.

[0078] When the light strip body 10 is bent in the opposite direction, the plate surfaces on both sides of the bending point of the light plate 15 (the plate surfaces on the side that are close to the silicone layer 12) move closer to each other. By using the fourth groove wall 115, the bending stress is diffused to the third light groove 113.

[0079] As an optional embodiment of the long cascaded light strip of this utility model, refer to Figures 2 to 4 The first light trough 111 includes a first trough segment 1111, a second trough segment 1112 and a third trough segment 1113 arranged in sequence; the second trough segment 1112 is connected to the second light trough 112.

[0080] The first slot 1111 is configured to allow space for one side of the lamp panel 15 to be placed; the third slot 1113 is configured to allow space for the other side of the lamp panel 15 to be placed; the lamp beads 154 are located in the second slot 1112 and the second lamp groove 112 respectively.

[0081] In this embodiment, the first groove segment 1111 and the third groove segment 1113 respectively limit the two sides of the lamp plate 15, and the second groove segment 1112 communicates with the second lamp groove 112 to avoid placing the lamp beads 154; so as to ensure that the lamp plate 15 is stably fixed in the lamp housing 11.

[0082] In some embodiments, the lamp 154 ​​is a monochrome temperature lamp.

[0083] In other embodiments, the lamp 154 ​​is a dual-color temperature lamp.

[0084] By changing the positive and negative connection of the external wire 30 to cascade with 13, the color temperature of the LED 154 can be switched.

[0085] When the external wire 30 is connected to the cascade 13 in the positive direction, the positive terminal of the external wire 30 is connected to the positive terminal 1301 of the cascade 13, and the negative terminal of the external wire 30 is connected to the negative terminal 1302 of the cascade 13; when the external wire 30 is connected to the cascade 13 in the reverse direction, the positive terminal of the external wire 30 is connected to the negative terminal 1302 of the cascade 13, and the negative terminal of the external wire 30 is connected to the positive terminal 1301 of the cascade 13.

[0086] The lamp beads include a first color temperature lamp body and a second color temperature lamp body; the first color temperature lamp bodies of all the lamp beads on the lamp board are connected in series to form a first color temperature circuit, and the second color temperature lamp bodies of all the lamp beads on the lamp board are connected in series to form a second color temperature circuit; the first color temperature circuit and the second color temperature circuit are connected in parallel to the power supply (through cascading to an external power supply). When the first color temperature circuit is connected to the power supply, the first color temperature lamp body in each lamp board is connected to the power supply. At this time, the emission color temperature of the long cascaded lamp strip of this invention is the color temperature of the first color temperature lamp body. When the second color temperature circuit is connected to the power supply, the second color temperature lamp body in each lamp board is connected to the power supply. At this time, the power of the long cascaded lamp strip of this invention is different from the power when the first color temperature circuit is connected to the power supply, and the emission color temperature is the color temperature of the second color temperature lamp body.

[0087] The main body 151 is an FPC board, and both surfaces of the main body 151 are conductive, which facilitates the welding of the main body 151 and the cascade band 13.
