Description

TECHNICAL FIELD

[0001] The utility model relates to atmosphere lamp technical field, concretely relates to atmosphere lamp soft light guide mounting structure based on soft guide plug connector. BACKGROUND

[0002] Linear light guide can be divided into two categories according to the soft and hard classification of texture, hard light guide is moulded by mould, not only surface and end face are relatively smooth, and integrally formed with light pattern, therefore, the utilization rate of light of hard light guide is high, and light guide performance is good, but due to the higher cost of mould, it is used for products with large output to obtain lower single-piece cost. The end face of soft light guide is cut, and in addition, soft light guide does not have optical pattern, and it is 360 degrees uniform light, so the light that can be used is usually only about 1 / 6 (generally, the light emitting area is about 60 degrees), so compared with hard light guide, soft light guide has lower brightness due to low optical utilization rate, but soft light guide does not have mould cost, and the price is determined by length, therefore, soft light guide is suitable for products with small output and aftermarket.

[0003] Please see Figure 1 For the current soft light guide mounting method, hot shrink tube 6 is first sleeved on the light guide mounting seat 211 of the lamp cap 2, then the soft light guide 1 is inserted into the light guide mounting seat 211, then the hot shrink tube 6 is heated for about 30 seconds by using a hair dryer, the hot shrink tube 6 is shrunk and tightly covers the light guide mounting seat and the soft light guide 1, finally, waiting for the hot shrink tube 6 to cool for about 1 minute, and the installation is completed. For the current soft light guide mounting method, the following problems exist:

[0004] 1, the two steps of heating and cooling are completed by workers manually, cannot be automated, and the flexible nature of the soft light guide 1 also leads to strong randomness and non-standard process;

[0005] 2, the process of processing the hot shrink tube 6 occupies a long time (about 90 seconds), and the workers will bear hot air when heating, and the working environment is relatively poor;

[0006] 3, after production, the hot shrink tube 6 cannot be detached and is a disposable product, so that it cannot be replaced and after-sales;

[0007] 4, the hot shrink tube 6 tightly adheres to the soft light guide 1 after cooling, and can absorb part of the light, so that the final light brightness is very low;

[0008] 5, when the soft light guide 1 is installed, the hot shrink tube 6 and the lamp cap 2 block the view, so that the installation distance between the LED and the soft light guide 1 cannot be seen, so that the spacing between the light inlet end surface of the soft light guide 1 and the light emitting surface of the LED is uncontrollable, thereby affecting the consistency of light efficiency.

[0009] Please see Figure 2To solve the problem of the above-mentioned 5th point, the existing soft light guide mounting structure sets a light guide positioning structure 211d in the light guide mounting hole 211a to limit the maximum insertion depth of the soft light guide 1, so as to ensure the spacing between the light inlet end face of the soft light guide 1 and the light emitting face of the LED, but the light guide positioning structure 211d will partially block the light inlet end face of the soft light guide 1, resulting in a decrease in the amount of light entering, and further reducing the light emitting brightness of the soft light guide 1. Utility model content

[0010] To solve the above technical problems, the utility model provides an atmosphere lamp soft light guide mounting structure based on a soft guide plug connector.

[0011] The technical scheme is as follows:

[0012] The first aspect of the present application relates to an atmosphere lamp soft light guide mounting structure based on a soft guide plug connector, comprising a soft light guide in a linear structure, at least one end of the soft light guide is provided with a lamp holder, the lamp holder comprises a lamp shell and a PCBA mounted in the lamp shell, a light guide mounting seat is arranged on the lamp shell, a light guide mounting hole is formed in the light guide mounting seat, a soft guide plug connector is detachably sleeved on the end of the soft light guide connected with the corresponding lamp holder, the soft guide plug connector is detachably mounted in the corresponding light guide mounting hole, and the light emitting face of the LED integrated on the PCBA is opposite to the light inlet end face of the soft light guide adjacent to the light inlet end face, and there is no shielding between the light emitting face and the light inlet end face.

[0013] By adopting the above atmosphere lamp soft light guide mounting structure based on a soft guide plug connector, the soft guide plug connector is first mounted on the soft light guide, and then the soft guide plug connector is mounted in the light guide mounting hole, which not only ensures the reliable mounting of the soft light guide, but also can accurately control the spacing between the light inlet end face of the soft light guide and the light emitting face of the LED by controlling the mounting position of the soft light guide on the soft guide plug connector, thereby ensuring the consistency of the light efficiency; the whole assembly process only has two steps of connecting the soft light guide with the soft guide plug connector and connecting the soft guide plug connector with the light guide mounting seat, which not only improves the assembly efficiency by dozens of times, but also is easy to standardize the process, can be assembled manually, and is easy to realize automatic assembly, at the same time, even if the manual assembly method is adopted, it will not cause relatively severe environmental factors, and the working environment is relatively more comfortable; and when the lamp holder cannot be lit, the lamp holder can be disassembled for maintenance or replacement by only separating the soft guide plug connector from the light guide mounting seat, the operation is simple, and the maintenance cost is low; and since the soft guide plug connector is an injection molded part, it will not be in full contact with the soft light guide, so compared with the contact between the heat shrink sleeve and the soft light guide, the absorption of light can be reduced, and the light emitting brightness of the soft light guide can be improved; in addition, since there is no shielding between the light emitting face of the LED and the light inlet end face of the soft light guide, more light can enter the soft light guide, thereby further improving the light emitting brightness of the soft light guide.

[0014] The gap between the adjacent light guide clamping portions does not completely block the soft light guide, thereby reducing light absorption and improving the light brightness of the soft light guide.

[0015] In some embodiments, the soft guide connector comprises two structurally consistent half assemblies, each of which has a planar structure on the side close to the other half assembly and a semicircular groove adapted to the soft light guide, each of which is provided with a clamping head on the same side of the semicircular groove and a clamping groove adapted to the clamping head on the other side. When the semicircular grooves of the two half assemblies enclose the circumferential outer wall of the end connected to the corresponding lamp holder of the soft light guide, the two clamping heads are respectively clamped into the corresponding clamping grooves to lock the soft light guide in the light guide positioning hole formed by the two semicircular grooves.

[0016] In some embodiments, the two half assemblies are each provided with a positioning pin on the same side of the semicircular groove and a positioning groove adapted to the positioning pin on the other side. When the semicircular grooves of the two half assemblies enclose the circumferential outer wall of the end connected to the corresponding lamp holder of the soft light guide, the positioning pins of the two half assemblies are respectively embedded in the corresponding positioning grooves.

[0017] In some embodiments, the side of each of the two half assemblies away from the other half assembly has a curved surface structure. When the semicircular grooves of the two half assemblies enclose the circumferential outer wall of the end connected to the corresponding lamp holder of the soft light guide, the sides of the two half assemblies away from each other enclose a circular ring structure. The side of each of the two half assemblies away from the other half assembly is provided with a rotating clamping pin protruding radially outward.

[0018] The hole wall of the light guide mounting hole is symmetrically provided with two rotating guide grooves extending in the circumferential direction. The same end of each of the two rotating guide grooves is a clamping pin locking position, and the other end is a clamping pin access position. The two rotating guide grooves are each contracted at a position close to the clamping pin locking position to form a clamping protrusion capable of limiting the rotating clamping pin in the clamping pin locking position. The hole wall of the light guide mounting hole is symmetrically provided with two access guide grooves extending outward from the corresponding clamping pin access position in the axial direction.

[0019] The two rotating clamping pins of the soft guide connector are first guided to the corresponding clamping pin access position through the corresponding access guide groove, then guided to the corresponding clamping pin locking position through the corresponding rotating guide groove, and locked by the corresponding clamping protrusion.

[0020] In some embodiments, the side of each of the two half assemblies away from the other half assembly protrudes radially to form a mounting stop at the end outside the light guide mounting hole. The outer end face of the light guide mounting seat abuts against the mounting stop of each of the two half assemblies. The clamping head and the clamping groove are formed on the mounting stop.

[0021] In some embodiments, the two half-assembly members are each formed with a diameter-reduced section in a semi-circular ring structure at one end thereof inserted into the light guide mounting hole, and the circumferential outer wall of the diameter-reduced section is in a conical surface structure gradually decreasing in diameter in a direction away from the mounting step.

[0022] In some embodiments, the groove wall of the semi-circular groove is in a frosted structure. BRIEF DESCRIPTION OF DRAWINGS

[0030] The present application is further described below in conjunction with embodiments and drawings.

[0031] As shown in the drawings, a soft light guide mounting structure of an atmosphere lamp based on a soft guide plug-in piece mainly comprises a soft light guide 1 in a linear structure, i.e., the soft light guide 1 is a linear light guide with soft texture, and specifically, the material of the soft light guide 1 is usually PMMA or PC, and the soft light guide 1 is very soft in texture after forming and is easy to bend. At least one end of the soft light guide 1 is provided with a lamp holder 2, i.e., one end of the soft light guide 1 is provided with the lamp holder 2, or both ends of the soft light guide 1 are provided with the lamp holder 2. Figures 3-7 The lamp holder 2 comprises a lamp shell 21 and a PCBA 22, the PCBA 22 is installed inside the lamp shell 21, and the PCBA 22 is integrated with an LED 221. The lamp shell 21 is provided with a light guide mounting seat 211, the light guide mounting seat 211 is provided with a light guide mounting hole 211a, and the light emitting surface of the LED 221 integrated on the PCBA 22 is opposite to the light guide mounting hole 211a.

[0032]

[0033] ​In the embodiment, the soft light guide 1 and the corresponding lamp holder 2 are detachably sleeved with the soft guide plug-in part 3 at one end, and the soft guide plug-in part 3 is detachably installed in the corresponding light guide mounting hole 211a.

[0034] Therefore, the embodiment can ensure the reliable installation of the soft light guide 1, and can accurately control the distance between the light inlet end face 11 of the soft light guide 1 and the light emitting face of the LED 221 by controlling the installation position of the soft light guide 1 on the soft guide plug-in part 3, thereby ensuring the consistency of the light efficiency. The entire assembly process only has two steps of connecting the soft light guide 1 with the soft guide plug-in part 3 and connecting the soft guide plug-in part 3 with the light guide mounting seat 211, which not only improves the assembly efficiency by tens of times, but also is easy to standardize the process, can be assembled manually, and is easy to realize automatic assembly. At the same time, even if the manual assembly method is adopted, it will not cause relatively severe environmental factors, and the working environment is relatively more comfortable. In addition, when the lamp holder 2 cannot be lit, the lamp holder 2 can be disassembled for maintenance or replacement by only separating the soft guide plug-in part 3 from the light guide mounting seat 211, which is simple to operate and has low maintenance cost.

[0035] Furthermore, since the soft guide plug-in part 3 is an injection molding part, it will not be in full contact with the soft light guide 1 in full contact, so compared with the contact of the heat shrink sleeve with the soft light guide 1, it can reduce the absorption of light and improve the light brightness of the soft light guide 1. Further, the groove wall of the semicircular groove 311 of the two half assembly parts 31 of the soft guide plug-in part 3 is frosted, so as to effectively reduce the contact area between the groove wall of the semicircular groove 311 and the soft light guide 1, further reduce the absorption of light, and improve the light brightness of the soft light guide 1.

[0036] Please refer to Figure 4 , the light emitting face of the LED 221 integrated on the PCBA 22 is directly opposite to the soft light guide 1 and the adjacent light inlet end face 11 thereof, and there is no shielding between the light emitting face of the LED 221 and the light inlet end face 11 of the soft light guide 1. Therefore, since there is no shielding between the light emitting face of the LED 221 and the light inlet end face 11 of the soft light guide 1, more light can enter the soft light guide 1, thereby further improving the light brightness of the soft light guide 1.

[0037] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the soft guide plug-in part 3 includes two half assembly parts 31 with consistent structures, which can be manufactured by only one injection molding mold, thereby having low mold cost and no mistake problem.

[0038] The two half-assembly parts 31 are both flat on the side close to each other, and are both concave to form a semicircular groove 311 matched with the soft light guide 1, so that when the two half-assembly parts 31 enclose the circumference of the soft light guide 1 through the respective semicircular grooves 311, the side surfaces of the two half-assembly parts 31 close to each other are in contact with each other.

[0039] The two half-assembly parts 31 are both provided with a clamping head 312 on the same side of the semicircular groove 311, and are both provided with a clamping groove 313 matched with the clamping head 312 on the other side, that is, the two half-assembly parts 31 are respectively provided with a clamping head 312 and a clamping groove 313 on the two sides of the semicircular groove 311, and the two clamping heads 312 are arranged on the same side of the corresponding semicircular groove 311, and the two clamping grooves 313 are arranged on the side of the corresponding semicircular groove 311 away from the clamping head 312. Therefore, when the semicircular grooves 311 of the two half-assembly parts 31 enclose the circumferential outer wall of the connecting end of the corresponding lamp holder 2 and the soft light guide 1, the two clamping heads 312 are respectively clamped into the corresponding clamping grooves 313 to lock the soft light guide 1 in the light guide positioning hole 32 formed by the two semicircular grooves 311, that is, the two half-assembly parts 31 clamp the soft light guide 1 therebetween, which is simple and reliable.

[0040] Further, the two half-assembly parts 31 are both provided with a positioning pin 314 on the same side of the semicircular groove 311, and are both provided with a positioning groove 315 matched with the positioning pin 314 on the other side, that is, the two half-assembly parts 31 are respectively provided with a positioning pin 314 and a positioning groove 315 on the two sides of the semicircular groove 311, and the two positioning pins 314 are arranged on the same side of the corresponding semicircular groove 311, and the two positioning grooves 315 are arranged on the side of the corresponding semicircular groove 311 away from the positioning pin 314. Therefore, when the semicircular grooves 311 of the two half-assembly parts 31 enclose the circumferential outer wall of the connecting end of the corresponding lamp holder 2 and the soft light guide 1, the positioning pins 314 of the two half-assembly parts 31 are respectively embedded in the corresponding positioning grooves 315, thereby ensuring the accuracy of the installation position of the two half-assembly parts 31.

[0041] Further, the side of the two half-assembly parts 31 away from each other is arc-shaped, and when the semicircular grooves 311 of the two half-assembly parts 31 enclose the circumferential outer wall of the connecting end of the corresponding lamp holder 2 and the soft light guide 1, the side of the two half-assembly parts 31 away from each other encloses a circular ring structure, so as to facilitate the rotation of the soft guide plug 3 in the light guide mounting hole 211a for locking or unlocking operation.

[0042] Specifically, the two half-assembly 31 are provided with a rotating latch 316 protruding radially outward on the side away from each other. The hole wall of the light guide mounting hole 211a is symmetrically provided with two sections of circumferentially extending rotating guide slots 211b, and the rotating latch 316 can slide along the corresponding rotating guide slot 211b. The same end of the two rotating guide slots 211b is the latch locking position 211b1, and the other end is the latch access position 211b2, that is, the rotating soft guide plug-in part 3 can make the two rotating guide slots 211b simultaneously located at the corresponding rotating guide slot 211b The latch locking position 211b1 or simultaneously located at the corresponding rotating guide slot 211b The latch access position 211b2.

[0043] At the same time, the two rotating guide slots 211b are contracted near the latch locking position 211b1 to form a clamping protrusion 211b3 that can limit the rotating latch 316 at the latch locking position 211b1, and the hole wall of the light guide mounting hole 211a is symmetrically provided with two sections of access guide slots 211c extending axially from the corresponding latch access position 211b2.

[0044] Therefore, when it is necessary to install the soft guide plug-in part 3 in the light guide mounting hole 211a, the two rotating latches 316 of the soft guide plug-in part 3 are first guided to the corresponding latch access position 211b2 through the corresponding access guide slot 211c, and then guided to the corresponding latch locking position 211b1 through the corresponding rotating guide slot 211b. At this time, the two rotating latches 316 are respectively locked by the corresponding clamping protrusion 211b3, and under the condition of no external force or small external force, the clamping protrusion 211b3 makes the two rotating latches 316 remain in the latch locking position 211b1.

[0045] When it is necessary to remove the soft guide plug-in part 3 from the light guide mounting hole 211a, a relatively large external force is first applied, and the two rotating latches 316 located in the latch locking position 211b1 are respectively extruded from the corresponding clamping protrusion 211b3 and slide along the rotating guide slot 211b to the latch access position 211b2, and then slide out to the outside of the light guide mounting hole 211a through the corresponding access guide slot 211c.

[0046] The above installation method not only has convenient operation, but also has high installation reliability, good stability, high assembly precision, and is not prone to loosening and abnormal sound problems.

[0047] Further, the width of the rotating guide slot 211b gradually increases from the clamping protrusion 211b3 towards the latch access position 211b2, which can avoid clamping stagnation and ensure the convenience of installation.

[0048] It should be noted that the cooperation between the soft guide plug-in part 3 and the light guide mounting hole 211a can also adopt a conventional installation cooperation mode such as clamping and thread locking.

[0049] Please see Figures 3-7 The two half assembly parts 31 are radially protruded with installation stop steps 317 at the end of the side far away from each other and outside the light guide installation hole 211a, and the outer end surface of the light guide installation seat 211 abuts against the installation stop steps 317 of the two half assembly parts 31, so as to accurately limit the installation depth of the soft guide plug 3.

[0050] Meanwhile, the clamping head 312 and the clamping groove 313 are formed on the installation stop step 317, which has high structural strength and good connection reliability.

[0051] Further, the two half assembly parts 31 are radially shrunk with a semi-circular ring structure of the shrunk section 318 at the end of the side far away from each other and inserted into the light guide installation hole 211a, and the circumferential outer wall of the shrunk section 318 is a taper surface structure with the diameter gradually decreasing away from the installation stop step 317 at the end far away from the installation stop step 317, so as to conveniently insert the soft guide plug 3 into the light guide installation hole 211a and ensure the convenience of assembly.

[0052] Finally, it should be noted that the above description is only the preferred embodiment of the present application, and those skilled in the art can make various similar expressions under the inspiration of the present application without violating the purpose and claims of the present application, and such changes fall within the protection scope of the present application.
