Description

Technical Field

[0001] The present invention relates to the technical field of atmosphere lamps, and in particular to a high-precision installation structure of a soft light guide for an atmosphere lamp capable of improving the brightness of the soft light guide. Background Art

[0002] Linear light guides can be divided into two categories: hard light guides and soft light guides according to the hardness of the texture. Hard light guides are made by injection molding, but due to the high mold cost, they are mostly used in products with large production volumes to obtain lower unit costs. The end faces of soft light guides are formed by cutting, there is no mold cost, and the price is determined by the length. Therefore, soft light guides are suitable for products with low production volumes and the aftermarket.

[0003] See also Figure 1 For the current installation method of the soft light guide, the heat shrink tube 6 is first put on the light guide mounting seat 211 of the lamp holder 2, and then the soft light guide 1 is inserted into the light guide mounting seat 211, and then the heat shrink tube 6 is heated for about 30 seconds with a hair dryer to shrink the heat shrink tube 6 and tightly cover the light guide mounting seat and the soft light guide 1, and finally the heat shrink tube 6 is cooled for about 1 minute to complete the installation. For the current installation method of the soft light guide, there are the following problems:

[0004] 1. Both the heating and cooling steps are done manually by workers and cannot be automated. The flexible nature of the soft light guide 1 also leads to high randomness and unstandardized processes.

[0005] 2. The process of processing the heat shrink tube 6 takes a long time (about 90 seconds), and the workers will be exposed to heat during heating, and the working environment is relatively poor;

[0006] 3. After production, the heat shrink tube 6 cannot be disassembled and is a disposable product, which makes it impossible to replace or provide after-sales service;

[0007] 4. After cooling, the heat shrink tube 6 is close to the soft light guide 1, which will absorb part of the light, making the final light output brightness very low;

[0008] 5. When installing the soft light guide 1, the heat shrink tube 6 and the lamp holder 2 block the field of vision, and the installation distance between the LED and the soft light guide 1 cannot be seen, resulting in uncontrollable spacing between the light-incoming end face of the soft light guide 1 and the light-emitting surface of the LED, thereby affecting the consistency of the light effect.

[0009] See also Figure 2 In order to solve the problem in point 5 above, the existing soft light guide installation structure sets a light guide positioning structure 211d in the light guide installation hole 211a for limiting the maximum insertion depth of the soft light guide 1, so as to ensure the distance between the light input end face of the soft light guide 1 and the light emitting surface of the LED. However, this light guide positioning structure 211d will partially block the light input end face of the soft light guide 1, resulting in a reduction in the amount of light input and a further reduction in the brightness of the light output of the soft light guide 1.

[0010] In addition, soft light guides have no optical patterns and emit light evenly at 360°, so usually only about 1 / 6 of the light can be used (the general light emission area is about 60°). Therefore, the optical utilization rate of soft light guides is low, resulting in unsatisfactory luminous brightness, which limits the promotion and application of soft light guides. Summary of the invention

[0011] In order to solve the above technical problems, the present invention provides a high-precision installation structure of a soft light guide for an ambient light, which can improve the brightness of the soft light guide.

[0012] The technical solution is as follows:

[0013] A first aspect of the present application relates to a high-precision installation structure for a soft light guide of an atmosphere lamp capable of improving the brightness of a soft light guide, comprising a soft light guide in a linear structure, wherein at least one end of the soft light guide is provided with a lamp holder, the lamp holders all include a lamp shell and a PCBA installed in the lamp shell, the lamp shells are provided with light guide mounting seats, the light guide mounting seats are provided with light guide mounting holes, the soft light guides are respectively detachably installed in the corresponding light guide mounting holes through soft guide connectors, the soft guide connectors have light guide positioning holes adapted to the soft light guides, the ends of the soft light guides are detachably installed in the light guide positioning holes from one end of the light guide positioning holes, the other ends of the light guide positioning holes are provided with focusing lenses, the light emitting surface of the LED integrated on the PCBA is directly opposite to the lens light inlet end face of the corresponding focusing lens, and there is no obstruction between the two, the lens light outlet end face of the focusing lens is directly opposite to the light guide light inlet end face of the soft light guide and the light guide adjacent thereto.

[0014] By adopting the above-mentioned high-precision installation structure of the soft light guide of the atmosphere lamp which can improve the brightness of the soft light guide, the end of the soft light guide and the focusing lens are first installed on the corresponding soft guide connector, and then the soft guide connector is installed in the corresponding light guide mounting hole. This not only ensures the reliable installation of the soft light guide, but also can accurately control the relative positions of the soft light guide, the focusing lens and the LED by controlling the installation positions of the soft light guide and the focusing lens on the soft guide connector, thereby ensuring the consistency of the light effect of the soft light guide. The entire assembly process has only two steps: connecting the soft light guide and the focusing lens with the soft guide connector and connecting the soft guide connector with the light guide mounting seat. This not only improves the assembly efficiency by dozens of times, but also makes it easy to standardize the process. It can be assembled manually or automatically. At the same time, even if manual assembly is adopted, it will not cause harsh environmental factors, and the working environment will be relatively more comfortable. Moreover, when the lamp head cannot be lit, the lamp head can be removed for repair or replacement by simply separating the soft guide connector from the light guide mounting seat. , simple operation and low maintenance cost; moreover, since the soft guide connector is an injection molded part, it will not have full-face contact with the soft light guide, so compared with the contact between the heat shrink sleeve and the soft light guide, it can reduce the absorption of light and improve the light output brightness of the soft light guide; in addition, since there is no obstruction between the light-emitting surface of the LED and the light-inlet end face of the focusing lens, more light can enter the soft light guide, thereby improving the light output brightness of the soft light guide; at the same time, by adding a focusing lens, the focusing lens can not only perfectly converge the light collected by the light-inlet end face of the lens into collimated light, so that the light entering the soft light guide is more concentrated, the utilization rate of the light is improved, and the light output brightness of the soft light guide is further improved, but also the shaping of the light is better, and the mixing of the light is more uniform, which effectively solves the problem of light dispersion and improves the comprehensive light effect of the light output of the soft light guide, and the light-outlet end face of the focusing lens can accurately define the position of the light-guide light-inlet end face of the soft light guide, further improving the installation position accuracy of the soft light guide.

[0036] The present invention is further described below in conjunction with embodiments and drawings.

[0037] like Figure 3-Figure 9 As shown, a high-precision installation structure of a soft light guide for an ambient light capable of improving the brightness of a soft light guide mainly comprises a soft light guide 1 in a linear structure, that is, the soft light guide 1 is a linear light guide with a soft texture. Specifically, the material of the soft light guide 1 is usually PMMA or PC, and the texture is very soft and easy to bend after molding. A lamp holder 2 is provided at least at one end of the soft light guide 1, that is, the lamp holder 2 is provided at one end of the soft light guide 1, or the lamp holders 2 are provided at both ends of the soft light guide 1.

[0038] The lamp holder 2 includes a lamp housing 21 and a PCBA 22, wherein the PCBA 22 is installed inside the lamp housing 21, and an LED 221 is integrated on the PCBA 22. A light guide mounting seat 211 is provided on the lamp housing 21, and a light guide mounting hole 211a is provided on the light guide mounting seat 211, and the light emitting surface of the LED 221 integrated on the PCBA 22 faces the light guide mounting hole 211a.

[0039] In this embodiment, the soft light guide 1 is detachably installed in the corresponding light guide installation hole 211a through the soft guide connector 3. Specifically, the soft guide connector 3 has a light guide positioning hole 32 adapted to the soft light guide 1, and the end of the soft light guide 1 can be detachably installed in the light guide positioning hole 32 from one end of the light guide positioning hole 32, and the other end of the light guide positioning hole 32 is installed with a focusing lens 4. In addition, the light-emitting surface of the LED 221 integrated on the PCBA 22 is directly opposite to the lens light-incoming end face 41 of the corresponding focusing lens 4, and there is no obstruction between the two, and the lens light-emitting end face 42 of the focusing lens 4 is directly opposite to the soft light guide 1 and the light guide light-incoming end face 11 adjacent to it.

[0040] Therefore, in this embodiment, the end of the soft light guide 1 and the focusing lens 4 are first installed on the corresponding soft guide connector 3, and then the soft guide connector 3 is installed in the corresponding light guide installation hole 211a, which not only ensures the reliable installation of the soft light guide 1, but also can accurately control the distance between the light guide light-incoming end face 11 of the soft light guide 1 and the lens light-emitting end face 42 of the focusing lens 4, and the distance between the lens light-incoming end face 41 of the focusing lens 4 and the light-emitting surface of the LED 221 by controlling the installation position of the soft light guide 1 and the focusing lens 4 on the soft guide connector 3 (that is, accurately control the relative positions among the soft light guide 1, the focusing lens 4 and the LED 22). Thereby, the consistency of the light effect of the soft light guide 1 is ensured; the whole assembly process has only two steps, namely, connecting the soft light guide 1 and the focusing lens 4 with the soft guide connector 3, and connecting the soft guide connector 3 with the light guide mounting seat 211. It not only improves the assembly efficiency by dozens of times, but also makes it easy to standardize the process, and can be assembled manually or easily realized automatically. At the same time, even if manual assembly is adopted, it will not cause harsh environmental factors, and the working environment will be relatively more comfortable. Moreover, when the lamp holder cannot be lit, it is only necessary to separate the soft guide connector 3 from the light guide mounting seat 211 to remove the lamp holder 2 for repair or replacement. The operation is simple and the maintenance cost is low.

[0041] In addition, since there is no obstruction between the light-emitting surface of LED221 and the light-inlet end face 41 of the focusing lens 4, more light can enter the soft light guide 1, thereby improving the light output brightness of the soft light guide 1; at the same time, by adding the focusing lens 4, the focusing lens 4 can not only perfectly converge the light collected by the lens light-inlet end face 41 into collimated light, but also make the light emitted from the lens light-emitting end face 42 and entering the soft light guide 1 more concentrated, thereby improving the utilization rate of the light, further improving the light output brightness of the soft light guide 1, but also better shaping the light, and at the same time, the mixing of the light is more uniform, which effectively solves the problem of light dispersion and improves the comprehensive light effect of the light output of the soft light guide 1.

[0042] Furthermore, the soft light guide 1 can be installed in a manner where the light guide light inlet end face 11 of the soft light guide 1 abuts against the lens light outlet end face 42 of the focusing lens 4, so that the lens light outlet end face 42 of the focusing lens 4 can accurately define the position of the light guide light inlet end face 11 of the soft light guide 1, further improving the installation position accuracy of the soft light guide 1.

[0043] Moreover, since the soft guide connector 3 is an injection molded part, it will not have a full contact surface contact with the soft light guide 1, so compared with the contact between the heat shrink sleeve and the soft light guide 1, it can reduce the absorption of light and improve the brightness of the light emitted by the soft light guide 1. Furthermore, the groove wall of the semicircular groove 311 of the two half-assemblies 31 of the soft guide connector 3 is a frosted structure, which can 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 brightness of the light emitted by the soft light guide 1.

[0044] In this embodiment, the flexible connector 3 includes two semi-assembly parts 31 with the same structure, and can be manufactured with only one injection mold, which not only reduces the mold cost but also eliminates the problem of error prevention.

[0045] The sides of the two semi-assemblies 31 that are close to each other are both planar structures, and are both recessed to form a semicircular groove 311 that is compatible with the soft light guide 1, so that when the two semi-assemblies 31 are surrounded by the circumferential outer side of the soft light guide 1 through their respective semicircular grooves 311, the surfaces of the sides of the two semi-assemblies 31 that are close to each other fit together.

[0046] The two half-assemblies 31 are both provided with a clamping joint 312 on the same side of the semicircular groove 311, and a clamping groove 313 matched with the clamping joint 312 is provided on the other side, that is, the two half-assemblies 31 are respectively provided with a clamping joint 312 and a clamping groove 313 on both sides of the semicircular groove 311, and the two clamping joints 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 joint 312. Therefore, when the semicircular grooves 311 of the two half-assemblies 31 are enclosed on the circumferential outer wall of the soft light guide 1 and the focusing lens 4, the two clamping joints 312 are respectively clamped into the corresponding clamping grooves 313 to lock the soft light guide 1 and the focusing lens 4 in the light guide positioning hole 32 enclosed by the two semicircular grooves 311, that is, the two half-assemblies 31 clamp the soft light guide 1 and the focusing lens 4 therebetween, which is simple and reliable.

[0047] Furthermore, the two half-assemblies 31 are provided with a positioning pin 314 on the same side of the semicircular groove 311, and a positioning groove 315 matched with the positioning pin 314 is provided on the other side, that is, the two half-assemblies 31 are provided with a positioning pin 314 and a positioning groove 315 on both sides of the semicircular groove 311, respectively, and the two positioning pins 314 are provided on the same side of the corresponding semicircular groove 311, and the two positioning grooves 315 are provided 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-assemblies 31 are enclosed on the circumferential outer wall of the soft light guide 1 and the focusing lens 4, the positioning pins 314 of the two half-assemblies 31 are respectively embedded in the corresponding positioning grooves 315, thereby ensuring the accuracy of the installation position of the two half-assemblies 31.

[0048] Furthermore, the sides of the two half-assemblies 31 that are away from each other are both arc-surface structures. When the semicircular grooves 311 of the two half-assemblies 31 are enclosed on the circumferential outer walls of the soft light guide 1 and the focusing lens 4, the sides of the two half-assemblies 31 that are away from each other are enclosed to form a circular ring structure, so that the soft guide connector 3 can be rotated in the light guide mounting hole 211a to perform locking or unlocking operations.

[0049] Specifically, the two semi-assemblies 31 are provided with a rotating bayonet 316 protruding radially outward on the side away from each other. Two sections of rotating guide grooves 211b extending in the circumferential direction are symmetrically provided on the hole wall of the light guide installation hole 211a, and the rotating bayonet 316 can slide along the corresponding rotating guide grooves 211b. The same end of the two rotating guide grooves 211b is a bayonet locking position 211b1, and the other end is a bayonet entry and exit position 211b2, that is, the rotating soft guide connector 3 can make the two rotating guide grooves 211b simultaneously located at the bayonet locking position 211b1 of the corresponding rotating guide groove 211b, or simultaneously located at the bayonet entry and exit position 211b2 of the corresponding rotating guide groove 211b.

[0050] At the same time, the two rotating guide grooves 211b are contracted at a position close to the pin locking position 211b1 to form a clamping protrusion 211b3 that can limit the rotating pin 316 at the pin locking position 211b1, and two sections of entry and exit guide grooves 211c extending outward along the axial direction from the corresponding pin entry and exit position 211b2 are symmetrically arranged on the hole wall of the optical waveguide mounting hole 211a.

[0051] Therefore, when the soft guide connector 3 needs to be installed in the optical guide mounting hole 211a, the two rotating pins 316 of the soft guide connector 3 are first guided to the corresponding pin entry and exit positions 211b2 through the corresponding entry and exit guide grooves 211c, and then guided to the corresponding pin locking positions 211b1 through the corresponding rotation guide grooves 211b. At this time, the two rotating pins 316 are respectively locked by the corresponding clamping protrusions 211b3. When no external force is applied or the external force is small, the clamping protrusions 211b3 keep the two rotating pins 316 in the pin locking positions 211b1.

[0052] When the flexible connector 3 needs to be removed from the optical guide mounting hole 211a, a relatively large external force is first applied, and the two rotating pins 316 located at the pin locking position 211b1 are respectively squeezed out from the corresponding clamping protrusions 211b3, and slide along the rotating guide groove 211b to the pin entry and exit position 211b2, and then slide out of the optical guide mounting hole 211a through the corresponding entry and exit guide groove 211c.

[0053] The above installation method is not only easy to operate, but also has high installation reliability and good stability. It has extremely high assembly accuracy and is not prone to loosening and abnormal noise problems.

[0054] Furthermore, the width of the rotating guide groove 211b gradually increases from the clamping protrusion 211b3 toward the direction close to the latch entry and exit position 211b2, which can avoid jamming and ensure the convenience of installation.

[0055] It should be pointed out that the cooperation between the flexible guide connector 3 and the light guide installation hole 211a can also adopt conventional installation cooperation methods such as snap-fitting, thread locking, etc.

[0056] The two semi-assemblies 31 have a mounting stop 317 radially protruding at one end thereof located outside the optical waveguide mounting hole 211a on the side away from each other. The outer end surface of the optical waveguide mounting seat 211 abuts against the mounting stop 317 of the two semi-assemblies 31, thereby accurately limiting the installation depth of the soft guide connector 3.

[0057] At the same time, the clamping joint 312 and the clamping groove 313 are both formed on the installation stop 317, which not only has high structural strength but also has good connection reliability.

[0058] Furthermore, the two semi-assemblies 31 have a reduced diameter section 318 with a semicircular structure at one end thereof inserted into the optical guide mounting hole 211a, and the circumferential outer wall of the reduced diameter section 318 has a conical structure at the end away from the mounting stop 317, the diameter of which gradually decreases in the direction away from the mounting stop 317, thereby making it easy to insert the soft guide connector 3 into the optical guide mounting hole 211a, thereby ensuring the convenience of assembly.

[0059] Furthermore, lens mounting holes 311a are provided in the semicircular grooves 311 of the two half-assemblies 31, and two lens positioning pins 44 respectively matched with the corresponding lens mounting holes 311a are protruded on the circumferential outer wall of the focusing lens 4. When the semicircular grooves 311 of the two half-assemblies 31 are enclosed on the circumferential outer walls of the soft light guide 1 and the focusing lens 4, the two lens positioning pins 44 are respectively embedded in the corresponding lens mounting holes 311a, thereby ensuring the reliable installation and installation accuracy of the focusing lens 4 on the soft guide connector 3.

[0060] See also Figure 5 and Fig. 9 The lens light-inlet end face 41 is a conical structure whose diameter gradually decreases in the direction away from the soft light guide 1. Therefore, the special structure of the lens light-inlet end face 41 can perfectly converge the collected light into collimated light, thereby making the light emitted from the lens light-emitting end face 42 and entering the soft light guide 1 more concentrated, thereby improving the utilization rate of the light and achieving the purpose of improving the soft light guide 1.

[0061] Furthermore, after the end of the focusing lens 4 away from the soft light guide 1 passes through the corresponding light guide positioning hole 32, the diameter is gradually expanded to form a conical boss 43 with a conical outer wall in the circumferential direction, and the lens light-incoming end face 41 with a conical structure is coaxially integrally formed on the end face of the conical boss 43 away from the soft light guide 1. Therefore, by adding the conical boss 43, not only can the light receiving area of ​​the lens light-incoming end face 41 be increased, but also the light inside the focusing lens 4 is fully reflected inside it, and will not escape from the circumferential side wall of the focusing lens 4, thereby improving the light output brightness of the lens light output end face 42.

[0062] At the same time, the lens light-emitting end face 42 is provided with a central optical tooth 422 located at the center thereof and a plurality of annular optical teeth 421 coaxially arranged around the central optical tooth 422, the diameters of the annular optical teeth 421 increase from the inside to the outside, the central optical tooth 422 is a spherical structure, the annular optical tooth 421 is composed of an annular wall surface 421a and an annular light-emitting surface 421b located outside the annular wall surface 421a, the annular wall surface 421a is a cylindrical surface structure extending toward the direction close to the light guide light-inlet end face 11, and the annular light-emitting surface 421b is an annular arc surface structure extending outward from the outer edge of the annular wall surface 421a. By designing the above-mentioned special light pattern on the lens light-emitting end face 42, not only can the emitted light be shaped, but also the light can be mixed more evenly, achieving an excellent light mixing effect, effectively solving the light dispersion problem, and improving the comprehensive light effect of the soft light guide 1.

[0063] See also Figure 3 and Figure 4 The lamp housing 21 is provided with a PCBA inlet and outlet 212 on a side away from the light guide mounting seat 211 , so that the PCBA 22 can be easily installed and removed.

[0064] At the same time, a rear cover 213 is integrally formed beside the PCBA inlet and outlet 212, which can be opened or covered on the PCBA inlet and outlet 212 by flipping, that is, the rear cover 213 is integrally formed with the lamp housing 21, and can be opened by flipping, or covered on the PCBA inlet and outlet 212. Compared with the traditional method of separating the lamp housing and the rear cover, one mold opening cost is reduced, thereby effectively reducing the cost.

[0065] Furthermore, a plurality of PCBA pressing ribs 213a and a plurality of rear cover clips 213b are integrally formed on the inner surface of the rear cover 213, and lamp housing clips 214 corresponding to the rear cover clips 213b are provided on the lamp housing 21. Therefore, when the rear cover 213 is covered on the PCBA inlet and outlet 212, the rear cover clips 213b are respectively inserted into the corresponding lamp housing clips 214, which is simple and reliable. At the same time, the PCBA pressing ribs 213a press the PCBA 22 tightly in the lamp housing 21, which ensures the installation reliability of the PCBA 22 and avoids abnormal noise.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
