Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible light strips, and in particular to a flexible LED light strip. BACKGROUND

[0002] LED light strips refer to the assembly of LEDs on a band-shaped FPC or PCB hard board. As the product shape resembles a strip, it is named as such. Flexible LED light strips, as a flexible lighting solution, are widely used in various decoration, lighting and indication scenarios.

[0003] However, traditional flexible LED light strips have significant limitations in design, especially in terms of angle adjustment and fixation. Specifically, most existing flexible LED light strips cannot achieve multi-directional angle adjustment, which greatly limits their applicability and flexibility in complex installation environments. Users often need to pre-customize light strips of specific angles according to installation locations, which not only increases costs but also reduces convenience of use.

[0004] In addition, even if some light strip designs allow for some degree of bending or angle adjustment, the connection after adjustment is usually fixed by means of adhesion.

[0005] This method requires workers to continuously assist in positioning during the drying process of the adhesive to prevent the adhesive position from cracking, which not only consumes time and effort but also greatly reduces installation efficiency. Especially in scenarios that require frequent adjustment or maintenance, the traditional adhesive fixation method is particularly inconvenient.

[0006] And when the light strip encounters a situation that needs to be hung and bent, the fixing effect at the hanging and bending part is poor, which cannot be fixed according to a specific shape.

[0007] Due to the lack of effective rigid support structure, traditional flexible LED light strips often have difficulty maintaining stability after adjusting the angle, and are prone to deviation or deformation due to external forces or their own gravity, thereby affecting the lighting effect and overall aesthetic. SUMMARY

[0008] The embodiment of the present application provides a flexible LED lamp strip, solves the problem that most existing flexible LED lamp strips cannot realize multidirectional angle adjustment in the prior art, which greatly limits the applicability and flexibility of the flexible LED lamp strips in complex installation environments; in addition, even if part of the lamp strip design allows a certain degree of bending or angle adjustment, the fixed connection position is usually fixed by means of gluing after adjustment. This method requires workers to continuously assist in positioning during the drying process of the glue to prevent the glued position from cracking, which not only consumes time and effort, but also greatly reduces the installation efficiency. Especially in scenarios that require frequent adjustment or maintenance, the traditional gluing fixing method is particularly inconvenient, and when the device needs to be suspended and bent, the fixing effect of the suspended and bent position is poor, so that the device cannot be fixed in a specific shape. When the device needs to be kept in a specific shape, two hemispherical clamping blocks are matched to form a sphere, which allows multidirectional rotation; by using a hot air blower to melt the paraffin capsule, the angle between the lamp strip components can be easily adjusted; after cooling, the paraffin solidifies to form a rigid support, realizing glue-free fixing and avoiding the problem of continuous manual fixing during the traditional gluing drying process; the pull rope cooperates with the elastic clamping block: pulling the pull rope makes the clamping blocks separate, and after loosening, the clamping blocks automatically reset by relying on the elasticity to clamp the paraffin capsule for position fixing; the connecting line is in a spiral shape in the rubber tube and can be stretched and contracted to buffer when bending, avoiding line breakage caused by pulling and improving durability.

[0071] Example one: as Figures 1-11As shown, the flexible LED lamp strip of the present application comprises a lamp strip assembly 100 and a connecting assembly 200, the lamp strip assembly 100 has a plurality of, the connecting assembly 200 is used for connecting adjacent lamp strip assemblies 100 and adjusting the angle between adjacent lamp strip assemblies 100;

[0072] In the initial state, the plurality of lamp strip assemblies 100 are arranged in a straight line in turn, the spacing between the connecting assembly 200 and the plurality of lamp strip assemblies 100 is consistent in number;

[0073] Specifically, the lamp strip assembly 100 can be bent according to the needs, so as to adapt to different installation positions and installation needs.

[0074] The lamp strip assembly 100 comprises a lamp holder 110, an adhesive layer 120, a lamp strip 130, a connecting piece 140 and a fixing frame 150;

[0075] The connecting assembly 200 comprises a clamping groove 210, a sliding port 211, a connecting rod 220, a clamping block 230, a fixing rod 240, a paraffin capsule 250 and a pull rope 260;

[0076] The clamping groove 210 is a sphere and is hollow inside, and the paraffin capsule 250 is fixed in the clamping groove 210;

[0077] The clamping groove 210 and the clamping block 230 are respectively arranged on the side of the adjacent two lamp holders 110 close to each other;

[0078] The clamping groove 210 is fixed at one end of the connecting rod 220, and the other end of the connecting rod 220 away from the clamping groove 210 is rotationally connected to the lamp holder 110;

[0079] The clamping block 230 is fixed on the fixing rod 240, and the other end of the fixing rod 240 away from the clamping block 230 is fixed on the lamp holder 110.

[0080] The connecting rod 220 and the fixing rod 240 are respectively arranged on the side of the adjacent two lamp holders 110 close to each other.

[0081] The paraffin capsule 250 is made of rubber, the paraffin capsule 250 is filled with paraffin, and the melting point of the paraffin in the paraffin capsule 250 is 60-70℃.

[0082] The clamping block 230 and the pull rope 260 are respectively two and one-to-one corresponding, the clamping block 230 is a hemisphere, the two clamping blocks 230 are mutually adhered to form a sphere, and the two clamping blocks 230 are mutually adhered and ball-hinged in the clamping groove 210;

[0083] Specifically, when adjusting the position, the paraffin in the paraffin capsule 250 is melted by the hot air blower or the hair dryer, so as to facilitate the torsion of the lamp holder 110. Since the ball hinge of the clamping block 230 is connected in the clamping groove 210, and the connecting rod 220 is rotationally connected on the lamp holder 110, the angle adjustment shape can be performed. After the adjustment shape is completed, the cold air blower or natural cooling is used, so as to fix the shape of the paraffin capsule 250, thereby fixing the position of the clamping block 230 in the clamping groove 210.

[0084] The pull rope 260 is fixed at both ends of the clamping block 230 and the lamp holder 110;

[0085] The clamping block 230 has elasticity, and the pull rope 260 is used to pull the clamping block 230, so as to generate a gap between the two clamping blocks 230 for clamping the paraffin capsule 250.

[0086] The clamping groove 210 is provided with a sliding opening 211 at an end away from the connecting rod 220, and the length of the sliding opening 211 is three-fourths of the maximum circumference of the clamping groove 210.

[0087] The pull rope 260 is fixed at an end of the clamping block 230 away from the fixing rod 240.

[0088] The lamp holder 110 fixed at an end of the pull rope 260 away from the clamping block 230 is the same as the clamping block 230 fixed on the lamp holder 110.

[0089] The clamping block 230 is tightly attached to the paraffin capsule 250 in the clamping groove 210.

[0090] Specifically, after the position of the clamping block 230 is adjusted, the two fingers pull the pull rope 260, so that the two clamping blocks 230 are away from each other. Then the pull rope 260 is released, and the clamping block 230 is reset by its own elastic force to clamp the paraffin capsule 250, thereby limiting and fixing the position.

[0091] The adhesive layer 120 is fixed on one side of the lamp holder 110, and the lamp strip 130 is fixed on the side of the lamp holder 110 away from the adhesive layer 120.

[0092] The surface of the adhesive layer 120 is covered with a release film.

[0093] The fixing frame 150 is provided with a plurality of fixing frames 150, and is fixed at both ends of the lamp strip 130. The fixing frame 150 is used to provide a bolt fixing position.

[0094] Specifically, when there is a part of the plane in the installation position, the user can peel off the release film on the surface of the adhesive layer 120, and paste the adhesive layer 120 for auxiliary fixing. Also, the bolt can pass through the fixing frame 150, so as to assist in fixing the position of the whole device.

[0095] The connecting piece 140 includes a rubber tube 141 and a connecting wire 142.

[0096] The rubber tube 141 and the connecting wire 142 are respectively fixed on two adjacent lamp strips 130, and the connecting wire 142 is electrically connected with the lamp strip 130, and is used for transmitting lighting power;

[0097] The connecting wire 142 is located in the rubber tube 141 and is in a spiral shape in an initial state.

[0098] Specifically, the connecting wire 142 is in a spiral shape in the rubber tube 141, and when the single lamp strip assembly 100 is bent, the spiral connecting wire 142 can be deformed to avoid being pulled to cause the connecting wire 142 to be broken.

[0099] The connecting assembly 200 further comprises a limiting groove 231.

[0100] The limiting groove 231 is arranged on the surface of the clamping block 230, and is in an arc shape and a plurality of limiting grooves 231 are evenly distributed on the clamping block 230.

[0101] Specifically, when the position is fixed, the paraffin capsule 250 can enter the limiting groove 231 to form a multi-point fixing effect, so that the spherical clamping block 230 is prevented from rotating in the clamping groove 210 to cause the position to be fixed to be poor.

[0102] One end of the connecting wire 142 in the lamp strip assembly 100 is electrically connected with the power supply, and is used for connecting overall power supply.

[0103] The two clamping blocks 230 are abutted and connected with the ball hinge in the clamping groove 210, which is prior art and will not be described herein.

[0104] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0105] When the device needs to be hung and bent and needs to be kept in a specific shape, the two hemispherical clamping blocks 230 are abutted to form a sphere, which is matched with the spherical clamping groove 210 to allow multi-directional rotation; the angle between the lamp strip assemblies 100 can be easily adjusted by using a hair dryer or a blower to melt the paraffin in the paraffin capsule 250; after cooling, the paraffin solidifies to form a rigid support, so that the problem of manual continuous fixing in the traditional gluing and drying process is avoided; the pull rope 260 cooperates with the elastic clamping block 230: pulling the pull rope 260 causes the clamping block 230 to separate, and after being loosened, the clamping block 230 is automatically reset by the elasticity to clamp the paraffin capsule 250 to fix the position; the connecting wire 142 is in a spiral shape in the rubber tube 141, and can be stretched and contracted to buffer when being bent, so that the line is prevented from being broken due to pulling, and the durability is improved.

[0106] In the embodiment one, the two clamping blocks 230 clamp the paraffin capsule 250 to fix the position, but during use, the paraffin capsule 250 is affected by the two clamping blocks 230 which are separated and closed, and the gravity of the paraffin filled in the paraffin capsule 250, so that the two clamping blocks 230 can only clamp a small part of the paraffin capsule 250; and after clamping, the surface of the paraffin capsule 250 has a certain elasticity, and the paraffin capsule 250 will gradually separate from the clamping of the two clamping blocks 230, so that the clamping fixing effect is gradually reduced; therefore, the scheme of the embodiment one is improved, as shown in Figure 12

[0107] The paraffin capsule 250 is filled with iron powder, and the paraffin in the paraffin capsule 250 is mixed with the iron powder;

[0108] The connecting assembly 200 further comprises a magnet 270.

[0109] The magnet 270 has two, corresponding to the two clamping blocks 230, and the two magnets 270 are fixed on the side of the two clamping blocks 230 close to each other.

[0110] Specifically, the magnet 270 can continuously adsorb the iron powder in the paraffin capsule 250, so that the paraffin capsule 250 deforms, and the surface of the paraffin capsule 250 is pulled into the two clamping blocks 230;

[0111] And when the magnet 270 adsorbs the iron powder in the paraffin capsule 250, it can fix the shape of the paraffin capsule 250 in the limiting groove 231, so as to avoid the influence of the elastic force of the paraffin capsule 250 itself, which causes the paraffin capsule 250 to be unable to completely fill the limiting groove 231.

[0112] The technical scheme in the above embodiment of the application has at least the following technical effects or advantages:

[0113] The magnet 270 adsorbs the iron powder, and the magnet 270 can continuously adsorb the iron powder in the paraffin capsule 250, so that the paraffin capsule 250 deforms, and the surface of the paraffin capsule 250 is pulled into the two clamping blocks 230, improving the clamping fixing effect of the clamping block 230; the magnet 270 is fixed on the inner side of the clamping block 230, and actively adsorbs the iron powder in the paraffin capsule 250, so that the paraffin capsule 250 is tightly attached to the limiting groove 231, avoiding separation due to gravity or elasticity, forming multi-point anchoring, and preventing displacement after angle adjustment.

[0114] In the above embodiment, during installation, the clamping block 230 is affected by gravity, and the worker cannot determine whether it is in the center position, so that the paraffin distributed between the clamping block 230 and the clamping groove 210 is uneven, the paraffin on one side is thick and the paraffin on the other side is thin, which reduces the fixing effect of the device after bending; therefore, the scheme of the embodiment two is improved, as shown in Figure 13 ​​

[0115] The connecting assembly 200 further comprises a gas supply pipe 232, a gas supply pipe 241, air bags 280 and a gas supply pipe 290;

[0116] The air bags 280 are multiple and are uniformly fixed on the two clamping blocks 230;

[0117] The gas supply pipe 232 is arranged in the clamping block 230, and the gas supply pipe 241 is arranged in the fixing rod 240. The gas supply pipe 232 is in communication with the air bags 280 and the gas supply pipe 241;

[0118] The gas supply pipe 290 is fixed on one side of the fixing rod 240 and is in communication with the gas supply pipe 241;

[0119] The gas supply pipe 290 is made of rubber and can be externally connected to a gas source.

[0120] Specifically, multiple air bags 280 are fixed on the outer surface of the clamping block 230. The air bags 280 are inflated, and the inflation degrees of the air bags 280 around are consistent. The air bags 280 are inflated to abut against the clamping groove 210, so that the clamping block 230 is located at the center of the clamping groove 210. The air bags 280 are inflated through the gas supply pipe 290, the gas supply pipe 232 and the gas supply pipe 241. The gas supply pipe 290 can be externally connected to a gas source. After inflation, the gas supply pipe 290 made of rubber is tied to complete the plugging operation.

[0121] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0122] The multiple air bags 280 are uniformly fixed on the surface of the clamping block 230 and uniformly abut against the inner wall of the clamping groove 210 after inflation, so as to automatically correct the position of the clamping block 230 and avoid the influence of uneven gravity distribution of the paraffin bag 250 on the fixing effect. The air bags 280 are inflated by externally connecting the gas source through the gas supply pipe 232 and the gas supply pipe 241 and the gas supply pipe 290. The inflation force of the air bags 280 can be accurately controlled to ensure that the clamping block 230 is always located at the center of the clamping groove 210.

[0123] The force applied by the air bag 280 is:

[0124]

[0125] Wherein, F is the normal force of a single air bag 280 on the inner wall of the clamping groove 210, and P is the inflation pressure;

[0126] A is the effective pressure bearing area of a single air bag 280. Assuming that each air bag 280 is hemispherical, the contact area is approximately the projection area under the condition of complete inflation and uniform contact, ;

[0127] Wherein, r is the radius of the air bag 280;

[0128] Total corrective force: , where n is the number of airbags 280.

[0129] Specific examples:

[0130] Number of airbags 280: 8;

[0131] Airbag 280 inflation pressure: 10 kPa;

[0132] Airbag radius: 0.003m;

[0133] A single airbag has an effective pressure-bearing area of ​​280 mm.

[0134]

[0135] Calculate the force F exerted by a single airbag 280:

[0136]

[0137] Calculate total corrective force :

[0138]

[0139] The total corrective force Ft = 2.2619 N. After the airbag 280 is inflated, it is evenly pressed against the inner wall of the slot 210. The resulting distributed normal force causes the card block 230 to automatically center and align, avoiding uneven distribution of paraffin inside the paraffin bag 250 due to gravity.
