Description

Technical Field

[0001] This utility model relates to the field of lighting, and in particular to a flexible lens and housing assembly structure and a lamp. Background Technology

[0002] In the design and manufacturing of linear lights, the lens and light source board are usually manufactured separately, and then assembled into a whole by a housing. In most existing linear light products, the lens is a rigid or brittle component. The lens and housing are usually connected by a snap-fit ​​mechanism with slots and protrusions. To reduce deformation and protect internal components, the housing is usually made of a material with high hardness and rigidity, such as aluminum alloy. This means that if the size of the slot and protrusion is too close when assembling the lens and housing, that is, the gap between them is too small, it will increase the difficulty of assembly, or even make assembly impossible. If the size of the slot is significantly larger than the size of the protrusion, that is, the gap between them is too large, it will cause the lens and housing to wobble easily, which is not conducive to obtaining stable illumination.

The light-incident side of the flexible lens is provided with a mounting surface. The pressing part can press the flexible lens against the light source plate and make the mounting surface fit against the light-emitting surface of the light source plate.

[0005] In some embodiments, the mounting surface is a plane, the housing has a groove, and the light source plate is fixed to the bottom surface of the groove.

[0006] In some embodiments, the crimping portion includes a connecting groove disposed on the sidewall of the groove; the flexible lens has a snap-fit ​​rib that is at least partially embedded in the connecting groove.

[0007] In some embodiments, the connecting slot includes two first slots respectively disposed on both sides of the groove, and the snap-fit ​​rib includes two first ribs disposed on both sides of the light-emitting side of the flexible lens, and the first slot engages with the first rib on the corresponding side.

[0008] In some embodiments, the opening of the first slot faces the bottom surface of the groove, and the free end of the first rib is raised in a direction away from the bottom surface of the groove.

[0009] In some embodiments, the bottom surface of the groove is provided with a snap-fit ​​component, and the snap-fit ​​component and the bottom surface of the groove form a first snap-fit ​​groove and a second snap-fit ​​groove with opposite openings. One side of the light source plate is embedded in the first snap-fit ​​groove, and the other side is embedded in the second snap-fit ​​groove.

[0010] In some embodiments, the flexible lens includes a lens optics portion and a protective rib, the protective rib being disposed on the outer side of the lens optics portion; the protective rib includes a first rib portion disposed on the light-incident side of the lens optics portion, the first rib portion having the mounting surface on the side away from the lens optics portion.

[0011] In some embodiments, the protective rib further includes a second rib portion, which is disposed on the side of the lens optical portion and surrounds the side of the lens optical portion to form a cavity, and the second rib portion is connected to the first rib portion.

[0012] In some embodiments, the light-incident side of the lens optics has a light-incident groove, and the mounting surfaces are provided on both sides of the light-incident groove, and the mounting surfaces on both sides are flush.

[0016] In a second aspect, the present invention provides a lamp, including the flexible lens and housing assembly structure described above.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The flexible lens and housing assembly structure of this utility model allows the flexible lens to be inserted into the housing through the housing's insertion interface. By using the flexible lens, its elastic deformation capability reduces the difficulty of insertion into the housing, and the elastic restoring force after deformation allows the flexible lens to be firmly clamped into the housing, reducing the shaking of the housing and the flexible lens.

By pressing and fixing the flexible lens with the pressing part, the overall deformation of the flexible lens can be used to easily insert the flexible lens into the housing during assembly, which helps to solve the problem that it is difficult for the protrusion to be inserted into the slot when only using the slot and protrusion to engage.

[0026] Example like Figures 1 to 8 As shown, in a first aspect, embodiments of this application provide a flexible lens and housing assembly structure, including a flexible lens 300, a housing 100 and a light source plate 200, wherein the light source plate 200 and the flexible lens 300 are both connected to the housing 100.

[0027] The flexible lens 300 has an incident light side 331 and an exit light side 332. In normal use, the light source plate 200 is opposite to the incident light side 331 of the flexible lens 300. The light emitted by the light source plate 200 enters the flexible lens 300 from the incident light side 331 and then exits from the exit light side 332. The flexible lens 300 can optimize the distribution, efficiency and visual effect of light by refracting, reflecting or scattering light.

[0028] In some embodiments, the light-incident side 331 of the flexible lens 300 is provided with a mounting surface 310, the mounting surface 310 is adapted to the shape of the light-emitting surface 210 of the light source plate 200, and the mounting surface 310 is in contact with the light-emitting surface 210 of the light source plate 200.

[0029] By setting the mounting surface 310 and making the mounting surface 310 fit against the light-emitting surface 210 of the light source plate 200, on the one hand, the displacement of the flexible lens 300 and the housing 100 in the light-emitting direction can be reduced, and on the other hand, the relatively large contact width between the mounting surface 310 and the light-emitting surface 210 can reduce the left and right sway of the flexible lens 300 relative to the light source plate 200 to a certain extent, so that the flexible lens 300 can remain relatively stationary with the light source plate 200, thereby improving the stability of the illumination.

[0030] The light emission direction mentioned in this embodiment refers to the light emission direction of the light source board 200, that is... Figure 1 in the Y direction.

[0031] In some embodiments, the housing 100 has a crimping portion to which the flexible lens 300 is connected, and the crimping portion is capable of pressing the flexible lens 300 against the light source plate 200.

[0032] By pressing the flexible lens 300 against the light source plate 200 through the pressing part, on the one hand, the displacement of the flexible lens 300 relative to the light source plate 200 in the Y direction can be reduced, and on the other hand, frictional resistance can be created between the mounting surface 310 and the light-emitting surface 210. The frictional resistance can help reduce the magnitude of the displacement of the flexible lens 300 relative to the light source plate 200 along the light-emitting surface 210, thereby keeping the mounting surface 310 in contact with the light-emitting surface 210 of the light source plate 200. This not only avoids the collision of components and the generation of abnormal noise, but also helps to obtain stable illumination and makes the actual values ​​of optical parameters closer to the optical design values.

[0033] The crimping part can be a specific structure or component provided on the housing 100, or it can be formed by the deformation of the housing 100 itself.

[0034] In some embodiments, the flexible lens 300 is a flexible component. Those skilled in the art will understand that in the prior art, some flexible lenses have higher temperature resistance than conventional lenses, and their application range is wider. For these flexible lenses, the assembly structure described in this embodiment can effectively control the shaking caused by the deformation of the flexible lens itself, compared with the assembly structure in which the lens and the light source plate 200 are spaced apart, which is conducive to obtaining stable illumination. This embodiment does not limit the material of the flexible lens. In the example, the flexible lens can be made by adding heat-resistant filler or using high-temperature silicone.

[0035] In some embodiments, the flexible lens 300 is further formed by an extrusion process.

[0036] In some embodiments, considering that the surface of the light source board 200 is usually flat, the mounting surface 310 is set to be flat to facilitate the mounting surface 310 to fit the light-emitting surface 210 of the light source board 200.

[0037] In some implementations, such as Figure 3 As shown, the housing 100 is provided with a groove 110, the light source plate 200 is fixed to the bottom surface of the groove 110, and at least one end of the housing 100 is provided with an insertion interface. The light source plate 200 and the flexible lens 300 can be inserted into the groove 110 of the housing 100 through the insertion interface. The insertion interface can be an end opening of the housing 100.

[0038] The flexible lens 300 can be installed entirely or partially in the groove 110, with the light-incident side 331 of the flexible lens 300 facing the bottom surface of the groove 110 and the light-exit side 332 located at the opening of the groove 110, where the opening refers to the open space opposite to the bottom surface of the groove 110. In this case, the housing 100 not only serves to maintain the relative positional relationship between the light source plate 200 and the flexible lens 300, but also serves to protect the light source plate 200 and the flexible lens 300.

[0039] After the light source board 200, flexible lens 300 and other components are assembled, the insertion interface can be sealed.

[0040] In this embodiment, the flexible lens and housing assembly structure allows the flexible lens 300 to be inserted into the housing 100 through its insertion interface. By using the flexible lens 300, its elastic deformation capability reduces the difficulty of insertion into the housing 100. Furthermore, the elastic recovery force of the flexible lens 300 after deformation allows it to clamp tightly onto the housing 100, reducing the shaking between the housing 100 and the flexible lens 300. An assembly surface 310 is provided on the light-incident side 331 of the flexible lens 300, and a pressing part is used to ensure proper assembly. The mating surface 310 is in contact with the light-emitting surface 210 of the light source plate 200, which can reduce the displacement of the flexible lens 300 and the light source plate 200 in the light-emitting direction, and to a certain extent reduce the left and right sway of the flexible lens 300 relative to the light source plate 200, which is conducive to obtaining stable illumination. The flexible lens 300 is pressed and fixed by the pressing part. During assembly, the overall deformation of the flexible lens 300 can be used to easily insert the flexible lens 300 into the housing 100, which helps to solve the problem that the protrusion is difficult to insert into the slot when only the slot and the protrusion are engaged.

[0041] Preferably, an assembly groove or assembly protrusion may be provided on the outer wall of the housing 100. The assembly groove and assembly protrusion can be used to connect with a fixed structure in the equipment or scene, so that the housing 100, the light source plate 200 and the flexible lens 300 are fixed to the fixed structure in the equipment or scene.

[0042] In some embodiments, the crimping portion includes a connecting groove disposed on the sidewall of the groove 110; the flexible lens 300 has a snap-fit ​​rib that is at least partially embedded in the connecting groove.

[0043] The connecting slot can be a groove-shaped structure set on the side walls of the groove 110, and the snap-fit ​​rib can be a protruding structure corresponding to the connecting slot. By embedding all or part of the snap-fit ​​rib into the connecting slot, the range of relative displacement between the flexible lens 300 and the housing 100 can be limited.

[0044] Furthermore, the connecting slot can press the flexible lens 300 against the light source plate 200 through the snap-fit ​​ribs.

[0045] In the example: the height of the connecting slot relative to the light-emitting surface 210 of the light source plate 200 can be set slightly lower than the height of the snap-fit ​​rib relative to the light-emitting surface 210 of the light source plate 200. When the snap-fit ​​rib is embedded in the connecting slot, the snap-fit ​​rib or the snap-fit ​​rib and other structures of the flexible lens 300 undergo elastic deformation, thereby pressing the flexible lens 300 against the light source plate 200 through elastic restoring force.

[0046] In some embodiments, the connecting slot includes a first slot 120, the opening of the first slot 120 facing the bottom surface of the recess 110, that is, facing the light source plate 200, and the snap-fit ​​rib includes a first rib 320, the free end of the first rib 320 curving away from the bottom surface of the recess 110, that is, curving away from the light source plate 200, and the first slot 120 and the first rib 320 are fitted together.

[0047] Furthermore, the groove depth direction of the first slot 120 is parallel to the upward direction of the first rib 320.

[0048] Furthermore, the connecting slot includes two first slots 120, which are respectively disposed on both sides of the groove 110, and the buckling rib includes two first ribs 320, which are respectively disposed on both sides of the light-emitting side 332 of the flexible lens 300.

[0049] By setting the opening of the first slot 120 to face the light source plate 200, the first slot 120 can have an inclined sidewall, which can limit the displacement of the first rib 320 in the X direction. By setting the first rib 320 to a raised structure, it is not only convenient to press the first ribs 320 on both sides into the corresponding first slots 120 at the same time, which helps to reduce the installation difficulty, but also reduces the risk of breakage when the first rib 320 undergoes slight elastic deformation.

[0050] In this embodiment, the X direction is parallel to the cross-section of the flexible lens 300 and perpendicular to the Y direction.

[0051] In some embodiments, depending on design and assembly requirements, the connecting slot may also include a number of second slots disposed on the side wall of the groove 110, and the snap-fit ​​rib may also include a number of second ribs adapted to the second slots. Through the interlocking of the second slots and the second ribs, the connection tightness between the housing 100 and the flexible lens 300 can be further increased.

[0052] In some embodiments, the bottom surface of the groove 110 is provided with a snap-fit ​​component 400, and the snap-fit ​​component 400 and the bottom surface of the groove 110 surround each other to form a first snap-fit ​​groove 410 and a second snap-fit ​​groove 420 with opposite openings. One side of the light source board 200 is embedded in the first snap-fit ​​groove 410 and the other side is embedded in the second snap-fit ​​groove 420.

[0053] like Figure 3As shown, the snap-fit ​​assembly 400 may include a first snap-fit ​​strip 430 and a second snap-fit ​​strip 440 spaced apart. The first snap-fit ​​strip 430 and the second snap-fit ​​strip 440 protrude from the bottom surface of the groove 110. The first snap-fit ​​strip 430 and the bottom surface of the groove 110 enclose each other to form a first snap-fit ​​groove 410. The second snap-fit ​​strip 440 and the bottom surface of the groove 110 enclose each other to form a second snap-fit ​​groove 420. The openings of the first snap-fit ​​groove 410 and the second snap-fit ​​groove 420 are opposite each other. The cross-section of the first snap-fit ​​strip 430 and the second snap-fit ​​strip 440 may be L-shaped.

[0054] The snap-fit ​​assembly 400 can be integrally formed with the housing 100. The width of the snap-fit ​​groove can be designed to be slightly smaller than the thickness of the light source board 200, so that when the light source board 200 is inserted into the snap-fit ​​groove, the two can achieve a tight connection through the elastic deformation of the material.

[0055] In some embodiments, the flexible lens 300 includes a lens optics section 330 and a protective rib 340. The lens optics section 330 is the main structure in the flexible lens 300 that plays a major role in light control, and the protective rib 340 is provided on the outer side of the lens optics section 330. For flexible lenses formed by extrusion, their structure is relatively soft when they are first extruded, and they are easily deformed or contaminated by collisions. By providing a protective rib 340 on the outer side of the lens optics section 330, the optical surface of the lens optics section 330 can be protected.

[0056] In some embodiments, the protective rib 340 further includes a first rib portion 341 and a second rib portion 342 connected to each other. The first rib portion 341 is disposed on the light-incident side 331 of the lens optical portion 330, and the second rib portion 342 is disposed on the side of the lens optical portion 330.

[0057] Preferably, the first rib portion 341 has a gap for light to pass through, and the light can be directed to the lens optical portion 330 through the gap.

[0058] Preferably, a mounting surface 310 is formed on the side of the first rib portion 341 away from the lens optical portion 330, that is, the mounting surface 310 is one side surface of the first rib portion 341, and the flexible lens 300 is attached to the light source plate 200 through the first rib portion 341.

[0059] Preferably, the second rib portion 342 and the side of the lens optical portion 330 are enclosed to form a cavity 342a; by forming the cavity 342a by partially spacing the second rib portion 342 and the side of the lens optical portion 330, sufficient space can be provided for the deformation of the second rib portion 342, and the deformation of the second rib portion 342 can be avoided from damaging the optical surface of the side of the lens optical portion 330.

[0060] In some embodiments, the lens optics 330 includes an incident light region, an exit light region, and a reflection region 333. The incident light region is located on the incident light side 331, the exit light region is located on the exit light side 332, and the reflection region 333 is located between the incident light region and the exit light region. It is used to reflect part of the light rays entering from the incident light region to the exit light region to improve the utilization rate of light. The incident light region may include an incident light surface, and the exit light region may include an exit light surface. External light rays may enter the lens optics 330 from the incident light surface, and after being refracted, reflected, or scattered by the lens optics 330, they are emitted from the exit light surface.

[0061] In some embodiments, the light-incident side 331 of the lens optics 330 has a light-incident groove 331a, the side and bottom surfaces of the light-incident groove 331a are light-incident surfaces, and the light-emitting surface 210 of the light source plate 200 is provided with a light-emitting unit 220, which corresponds to the light-incident groove 331a. The light emitted by the light-emitting unit 220 can enter the lens optics 330 from the light-incident surface in the light-incident groove 331a.

[0062] In some embodiments, the light inlet groove 331a is further provided with mounting surfaces 310 on both sides, and the mounting surfaces 310 on both sides are flush.

[0063] Furthermore, the first rib portion 341 protrudes from the side wall of the light groove 331a, as shown below. Figure 5 As shown, this can protect the sidewalls of the light inlet slot 331a to a certain extent.

[0064] In some embodiments, further, in cross-section, the sum of the widths of the mounting surfaces 310 is B, and the total width of the light-incident side 331 of the flexible lens 300 is b, where B ≥ b.

[0065] For multiple assembly surfaces 310, the sum of the widths of the assembly surfaces 310 is the sum of the widths of each assembly surface 310. For example: Figure 5 As shown in the figure, there are two assembly surfaces 310, one on the left and one on the right. The widths of the two assembly surfaces 310 are B1 and B2, respectively. Therefore, the sum of the widths of the assembly surfaces 310 is B = B1 + B2.

[0066] The total width of the incident light side 331 of the flexible lens 300 refers to the width between the left and right edges of the incident light side 331, such as... Figure 5 By making B≥b, the flexible lens 300 can have a sufficiently large mounting surface 310, which helps to reduce the wobbling of the flexible lens 300 relative to the light source plate 200 in the X direction.

[0067] In some embodiments, both the housing 100 and the flexible lens 300 are strip-shaped components. The housing 100 can be formed by a stretching process, and the flexible lens 300 can be integrally formed by an extrusion process.

[0068] Preferably, the light source board 200 can be one or more boards arranged along the extension direction of the housing 100, and the whole composed of one or more light source boards 200 is provided with a plurality of light-emitting units 220 arranged at intervals along the extension direction of the housing 100.

[0069] The light source board 200 can be a PCB board, and the light-emitting unit 220 can be an LED bead or an LED chip.

[0070] This embodiment does not limit the type of the lens optics 330, which can be a convex lens, a concave lens, a perspective lens, etc.; this embodiment also does not limit the shape of the flexible lens 300, which can be semi-circular, circular, elliptical, square, etc.; this embodiment also does not limit the shape of the light-incident surface and the light-exit surface, which can be planar, curved, or other irregular surfaces, and microstructures can be provided on the light-incident surface and the light-exit surface as needed to adjust the light distribution; this embodiment also does not limit the length of the housing 100 and the flexible lens 300.

[0071] The assembly method of the flexible lens and housing assembly structure described in this embodiment: S1. The housing 100, the light source plate 200 and the flexible lens 300 are prefabricated, and at least one end of the housing 100 is open; S2. Insert the light source board 200 into the housing 100 from one end of the housing 100 along the first snap-fit ​​groove 410 and the second snap-fit ​​groove 420; Insert the flexible lens 300 into the housing 100 from one end of the housing 100 along the connecting slot.

[0072] It is understood that the insertion order of the light source plate 200 and the flexible lens 300 can be adjusted according to actual assembly needs, and this embodiment does not limit it.

[0073] Preferably, if the light source plate 200 is inserted into the housing 100 first, when inserting the flexible lens 300, the first rib 320 is first inserted into the corresponding first slot 120, and then a force away from the light source plate 200 is applied to the flexible lens 300 to cause the first rib 320 to undergo a slight deformation so that the mounting surface 310 is higher than the light-emitting surface 210 of the light source plate 200, and then the lower part of the flexible lens 300 is inserted into the housing 100.

[0074] The assembly structure described in this embodiment is easier to install than conventional assembly structures and is suitable for heat-resistant flexible lenses, enabling more precise relative assembly dimensions between the flexible lens and the PCB board.

[0075] In a second aspect, embodiments of this application provide a lamp, including the flexible lens and housing assembly structure described above.

[0076] In some embodiments, the luminaire is an LED linear light. The light emitted by the light-emitting unit 220 on the light source board 200 is adjusted by the flexible lens 300 and then emitted to form the lighting required by the design.
