Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting component and a floor lamp. Background Technology

[0002] To adjust the illumination range of a luminaire, a lens or lens assembly can be placed in front of the light source to shape the emitted light. The illumination range can be altered by changing the distance between the lens and the light source or by changing the equivalent focal length of the lens assembly itself. This requires the lens to move; the lens can be threaded onto the luminaire's housing, allowing movement by rotating it. However, threaded connections require high manufacturing precision to ensure a tight fit between the lens and the housing and prevent wobbling, resulting in higher manufacturing costs. Utility Model Content

[0003] The main purpose of this invention is to provide a lighting component and a floor lamp, which aims to reduce the manufacturing cost of the lighting component.

[0004] To achieve the above objectives, the present invention proposes an illumination assembly comprising a light source, a housing, a lens and a fixing member fixedly connected to each other. Both the light source and the fixing member are disposed within the housing, and the lens is used to shape the emitted light from the light source. One of the fixing member and the housing is provided with a limiting protrusion, and the other is provided with a limiting groove, with the limiting protrusion slidingly engaging with the limiting groove. The limiting groove is strip-shaped, and its length direction is the same as the light emission direction of the light source; the limiting protrusions are distributed along the length direction of the limiting groove.

[0005] In some embodiments, the limiting protrusion includes a limiting rib, which is strip-shaped and its length direction is the same as that of the limiting groove.

[0006] In some embodiments, the housing includes a fixedly connected outer shell and a bracket; the bracket, the outer shell, and the fastener are all cylindrical, and the bracket is coaxially disposed inside the outer shell, with the axial direction of the bracket being the same as the light emission direction of the light source;

[0007] The limiting protrusion is disposed on the radial inner side of the bracket, and the limiting groove is disposed on the radial outer side of the fixing member; or the limiting protrusion is disposed on the radial outer side of the bracket, and the limiting groove is disposed on the radial inner side of the fixing member.

[0008] In some embodiments, the fastener includes a first mating portion and a second mating portion that are connected and both are cylindrical; the second mating portion is coaxially disposed within the first mating portion; the radially inner side of the first mating portion mates with the radially outer side of the bracket, and the radially outer side of the second mating portion mates with the radially inner side of the bracket.

[0009] In some embodiments, the support includes a cylindrical portion and an abutment portion, the abutment portion being disposed radially outside the cylindrical portion, the axial direction of the cylindrical portion being the same as the light emission direction of the light source, and the abutment portion being polygonal in cross-section perpendicular to the axial direction of the cylindrical portion; the radially inner side of the first mating portion abuts against the abutment portion.

[0010] In some embodiments, the first mating part is provided with an abutting rib on its radially inner side. The abutting rib is strip-shaped, and the length direction of the abutting rib is the same as the light emission direction of the light source.

[0011] In some embodiments, the lighting assembly further includes a damping ring fitted radially outward of the fixing member and abutting against the radially inward side of the bracket.

[0012] In some embodiments, the fixing member includes a first clamping member and a second clamping member connected to each other; the first clamping member abuts against the light-emitting side of the lens, and the second clamping member abuts against the light-incident side of the lens, so as to clamp the lens.

[0013] In some embodiments, the first clamping member and the second clamping member are snap-fitted together; and / or

[0014] One of the first clamping member and the second clamping member is provided with an anti-rotation rib, and the other of the first clamping member and the second clamping member is provided with an anti-rotation groove; both the anti-rotation rib and the anti-rotation groove are strip-shaped, and the length direction of both the anti-rotation rib and the anti-rotation groove is the same as the optical axis direction of the lens; the anti-rotation rib cooperates with the anti-rotation groove.

[0015] This utility model also proposes a floor lamp, including the above-mentioned lighting component, lamp holder and universal head; the lighting component is rotatably connected to the universal head, and the universal head is connected to the lamp holder.

[0016] In the technical solution of this utility model, the fixing member is connected to the lens, so the movement of the fixing member can drive the movement of the lens. The limiting protrusion cooperates with the limiting groove. Since the length direction of the limiting groove is the same as the light emission direction of the light source, when the limiting protrusion and the limiting groove slide relative to each other, the lens can move in the light emission direction of the light source, thereby changing the illumination range of the light source.

[0017] Meanwhile, since the limiting protrusions are distributed along the length of the limiting groove, the limiting protrusions have at least two mutually spaced contact positions with the limiting groove along the length of the limiting groove. In this way, the limiting groove can prevent the limiting protrusions from rotating around an axis perpendicular to the length of the limiting groove, thereby preventing the lens from rotating around the same axis. At the same time, since the groove wall of the limiting groove abuts against the limiting protrusions, it can prevent the fixing member from rotating around an axis along the length of the limiting groove, thereby preventing the lens from rotating around the same axis.

[0018] Therefore, the technical solution of this application can impede lens rotation in at least two mutually perpendicular directions, thereby reducing lens wobble. Furthermore, due to the use of a limiting protrusion and a limiting groove, no threaded structure is required, resulting in lower machining precision requirements and thus lower cost. This provides a lighting component with less wobble and lower manufacturing cost. Attached Figure Description

[0046] This utility model proposes a lighting component.

[0047] Please refer to Figure 1 and Figure 2 The lighting assembly 10 proposed in this utility model includes a light source 11, a housing 12, a lens 13 and a fixing member 14 fixedly connected to each other. The light source 11 and the fixing member 14 are both disposed within the housing 12, and the lens 13 is used to shape the emitted light from the light source 11. Please refer to further details. Figure 3 One of the fixing member 14 and the housing 12 is provided with a limiting protrusion 15, and the other of the fixing member 14 and the housing 12 is provided with a limiting groove 16. The limiting protrusion 15 and the limiting groove 16 are slidably engaged. The limiting groove 16 is strip-shaped, and the length direction of the limiting groove 16 is the same as the light emission direction of the light source 11. The limiting protrusions 15 are distributed along the length direction of the limiting groove 16.

[0048] The lighting component 10 is a component that can emit light independently after being powered on. Its light emission state can be changed by external circuitry, but it can also have its own control circuitry to adjust its own light emission state (including whether it emits light, the color of the light emitted, the angle of the light emitted, and the brightness). In one example, the lighting component 10 can be the part of a flashlight excluding the battery and power supply circuitry; in another example, the lighting component 10 can be the part of a stage spotlight excluding the rotatable base; in yet another example, the lighting component 10 can be the lamp head of a lamp fixture (such as a table lamp or a floor lamp).

[0049] Therefore, the lighting assembly 10 includes a light source 11, which is a light-emitting component. The light source 11 includes at least one lamp bead 111, which may include an LED (Light-emitting Diode), a fluorescent lamp, an incandescent lamp, and / or an LD (Laser Diode). At least one lamp bead 111 may be provided. When multiple lamp beads 111 are provided, they can emit different colors. Thus, adjusting the brightness of different lamp beads 111 changes the color of the light emitted by the lighting assembly 10.

[0050] exist Figure 2 In the illustrated embodiment, the light source 11 includes LED beads 111 and a light mixer 112. Because the LED beads 111 are physically spaced apart, the emitted light from the lighting assembly 10 may have different intensities in different directions. The light mixer 112 can make the emitted light from the lighting assembly 10 more uniform. In some embodiments, there are multiple LED beads 111, which can emit light of different colors with intensities varying according to a control signal. In this case, the light mixer 112 can also mix the colors, making the emitted light from the lighting assembly 10 uniform in color.

[0051] The housing 12 serves as the mounting base for the optical elements and / or electronic and electrical components of the lighting assembly 10. Therefore, it should be noted that in some embodiments, the housing may not be shell-shaped; for example, it may be in the shape of a bracket, as long as it provides a mounting base for the optical elements and / or electronic and electrical components. In some embodiments, a button 1211 for controlling the lighting assembly 10, and a PCB (Printed Circuit Board) control board that receives control signals from the button 1211 and controls the light emission state of the light source 11, may be mounted on the housing 12.

[0052] A lens is an optical element that shapes light rays. In some embodiments, lenses are classified by their surface type, such as spherical lenses, aspherical lenses, or freeform lenses. In other embodiments, lenses are classified by their shape, such as plano-convex lenses, biconvex lenses, meniscus lenses, or Fresnel lenses. A single lens may be used, or multiple lenses may be used.

[0053] Lens 13 can be positioned in front of light source 11, i.e., on the light-emitting side of light source 11, so that the emitted light from light source 11 can enter lens 13, allowing lens 13 to shape the emitted light from light source 11. This shaping can simply change the illumination range of illumination assembly 10. In one example, the lens can have positive optical power, thus concentrating the emitted light from the light source towards the optical axis of the lens, resulting in a smaller illumination range and greater light intensity.

[0054] Lenses can also shape light sources to increase the illumination range. In one example, a lens can have a negative optical power, which can cause the emitted light from the light source to move away from the optical axis of the lens, thereby increasing the illumination range.

[0055] Lenses can also shape light sources by altering the light intensity distribution. In one example, the lens can be an aspherical lens or a freeform lens, making the light intensity distribution of the emitted light from the lighting assembly more uniform at various emission angles.

[0056] Lenses can also shape light sources to give the emitted light a specific pattern. In this type of implementation, the lens is usually an aspherical lens, which has a projection effect.

[0057] Moving the lens can generally change its shaping effect on the light source. In one example, the lens is set with one lens and has a positive optical power. When the lens is moved, the light source is always within one focal length of the lens. The farther the lens is from the light source, the smaller the illumination range (the illumination range can be understood as the half-intensity angle of the light emitted by the lighting component 10), and vice versa.

[0058] like Figure 2 and Figure 3 In the embodiment shown, lens 13 can have positive optical power, and light source 11 can be within one focal length of lens 13. Figure 2 The illumination range shown is greater than Figure 3 The illumination range shown is larger; this is because, as can be seen from the figure, Figure 2 In this state, lens 13 is closer to light source 11.

[0059] However, the movement of the lens is not limited to the movement of a single lens relative to the light source. In some implementations, multiple lenses can be provided, and multiple lenses can be combined to form a lens group. In this way, the shaping effect of the lens group can be judged by the equivalent focal length of the lens group. At this time, individual (one or more) lenses in the lens group can be moved. Moving individual lenses changes the overall equivalent optical power of the lens group, thereby changing the shaping effect on the light source.

[0060] The fixing component 14 is a component for fixing the lens 13. The lens 13 can be fixedly connected to the fixing component 14 by means of bonding, welding, screwing and riveting. The fixing component 14 can be cylindrical or bracket-shaped, but the fixing component 14 needs to expose the part of the lens 13 that mainly participates in shaping to the light source 11 and the light outlet of the illumination assembly 10 so that the lens 13 can work normally.

[0061] The fixing member 14 is disposed inside the housing 12. It can be considered that the fixing member 14 and the housing 12 are in direct or indirect sliding fit. Thus, when the fixing member 14 moves inside the housing 12, it can drive the lens 13 to move, thereby changing the shaping effect of the lens 13 on the emitted light of the lighting component 10.

[0062] The fixing member 14 is prone to wobbling when moving relative to the housing 12. Therefore, a limiting protrusion 15 and a limiting groove 16 are provided to prevent the fixing member 14 from wobbling relative to the housing 12. Figure 3 In the illustrated embodiment, the limiting groove 16 is visible on the housing 12, while the limiting protrusion 15 (in) Figure 3 In the embodiment shown in the example of the limiting rib 151, it is provided on the fixing member 14. In other embodiments, the above relationship can be reversed, that is, the limiting groove 16 is provided on the fixing member 14, and the limiting rib 15 is provided on the housing 12.

[0063] The limiting protrusion 15 slides into the limiting groove 16, meaning that at least part of the limiting protrusion 15 can enter the limiting groove 16. This allows the portion of the limiting protrusion 15 entering the limiting groove 16 to interact with the groove wall, achieving a sliding fit. The sliding direction is the same as the length direction of the limiting groove. It is understandable that if the lens 13 needs to change the shaping effect on the light emitted from the light source 11 by moving, whether directly changing the distance between the lens 13 and the light source 11 or changing the positional distribution of individual lenses 13 in the lens group, the lens 13 generally moves along the light emission direction of the light source 11. Therefore, since the length direction of the limiting groove 16 is the same as the light emission direction of the light source 11, when the fixing member 14 moves the lens 13, it slides within the limiting groove 16 along the light emission direction of the light source 11.

[0064] The light emission direction of light source 11 can refer to the optical axis direction of light source 11, or it can refer to the central axis of the half-intensity angle of light emission of light source 11. For light source 11 using LEDs for lamp beads 111, the light emission direction of light source 11 can be determined by the normal direction of the light emission surface of any lamp bead 111, or by the direction of the maximum light intensity angle of lamp bead 111. Since the light intensity distribution of the emitted light of LED lamp beads 111 generally conforms to the Lambertian distribution law, the direction of the maximum light intensity angle generally coincides with the normal direction of the light emission surface.

[0065] When the light source 11 is an incandescent lamp or a fluorescent lamp, the light emission direction of the light source 11 can be determined by combining the axial direction of the entire lighting assembly 10. That is, in this type of implementation, the light emission direction of the light source 11 can refer to the light emission direction of the lighting assembly 10, or when the lighting assembly 10 has an axis, the light emission direction of the light source 11 can be the axial direction of the lighting assembly 10.

[0066] The fact that the limiting protrusions 15 are distributed along the length of the limiting groove 16 means that the limiting protrusions 15 have at least two mutually spaced contact points with the limiting groove 16 along the length of the limiting groove 16. Figure 3 In the embodiment shown, the limiting rib 151 is strip-shaped and its length direction is along the length direction of the limiting groove 16, so that there can be an infinite number of contact positions between the limiting rib 151 and the limiting groove 16.

[0067] In other embodiments, the limiting protrusion may include two limiting posts, which are spaced apart along the length of the limiting groove. The two limiting posts enter the limiting groove to cooperate with it. The axial direction of the two limiting posts is the same as the opening direction of the limiting groove. Thus, one limiting post has a contact position with the limiting groove. Since the two limiting posts are spaced apart along the length of the limiting groove, the limiting protrusion has two spaced-apart contact positions with the limiting groove along the length of the limiting groove.

[0068] The presence of the aforementioned spaced-apart contact points ensures that the engagement between the limiting protrusion 15 and the limiting groove 16 can at least restrict the rotation of the fixing member 14 along one axial direction, which is the opening direction of the limiting groove 16. For an example, please refer to... Figure 3 ,exist Figure 3 Within the plane, draw an axis perpendicular to the length of the limiting rib 151, which is the aforementioned axis. It can be seen that the limiting groove 16 can restrict the limiting rib 151 to prevent the fixing member 14 from rotating along this axis.

[0069] Due to the cooperation between the limiting groove 16 and the limiting protrusion 15, the fixing member 14 can be naturally prevented from rotating along another axis, namely the axis along the optical axis of the lens 13. Please refer to... Figure 5 and Figure 6 This axis is perpendicular Figure 6 As shown in the cross-section, the engagement of the limiting rib 151 and the limiting groove 16 restricts the rotation of the fixing member 14 along this axis. It is understandable that... Figure 6 If the limiting rib 151 in the embodiment shown is replaced with the limiting post described above, it can also play the role of limiting the rotation of the fixing member 14 along the axis.

[0070] In addition, the limiting groove 16 can be as follows: Figure 2 or Figure 6The example shown is a blind groove, but in other embodiments, the limiting groove can also be a through groove, for example, it can be in the shape of an oblong hole. This does not affect the limiting groove's function of hindering the rotation of the fixing member.

[0071] As can be seen, due to the cooperation of the limiting groove 16 and the limiting protrusion 15, the fixing member 14 can prevent the lens 13 from rotating relative to the housing 12 in at least two mutually perpendicular directions, which reduces the wobble of the lens 13 relative to the housing 12. At the same time, due to the cooperation of the limiting protrusion 15 and the limiting groove 16, the position of the lens 13 can be adjusted by pulling the fixing member 14 instead of rotating the fixing member 14. This eliminates the need for a threaded structure, reduces the requirement for machining accuracy, and lowers the cost. Therefore, the lens 13 of the lighting assembly 10 provided in this application has less wobble, and the manufacturing cost of the lighting assembly 10 is also lower.

[0072] Please refer to Figure 3 and Figure 11 In some embodiments, the limiting protrusion 15 includes a limiting rib 151, which is strip-shaped and has the same length direction as the limiting groove 16.

[0073] As mentioned above, the limiting rib 151 can be considered to have an infinite number of contact positions compared to the limiting groove 16. Thus, as long as the limiting rib 151 does not detach from the limiting groove 16, it can be assumed that the limiting rib 151 and the limiting groove 16 have at least two mutually spaced contact positions along the length of the limiting groove 16. This allows the fixing member 14 to obtain good limiting at various positions during the movement process, preventing the lens 13 from shaking.

[0074] Please refer to Figure 2 and Figure 7 In some embodiments, the housing 12 includes a fixedly connected outer shell 121 and a bracket 122; the bracket 122, the outer shell 121 and the fixing member 14 are all cylindrical, and the bracket 122 is coaxially disposed inside the outer shell 121, with the axial direction of the bracket 122 being the same as the light emission direction of the light source 11; a limiting protrusion 15 is disposed on the radial inner side of the bracket 122, and a limiting groove 16 is disposed on the radial outer side of the fixing member 14; or the limiting protrusion 15 is disposed on the radial outer side of the bracket 122, and the limiting groove 16 is disposed on the radial inner side of the fixing member 14.

[0075] The phrase "cylindrical" above can be understood as "at least partially cylindrical," meaning it does not exclude the possibility of non-cylindrical portions. For an example, please refer to [reference needed]. Figure 2 The bracket 122 has a flange structure at its lower part, allowing the outer casing 121 and the bracket 122 to be connected by screws 1224. The flange structure is the non-cylindrical portion of the bracket 122. The cylindrical shape does not necessarily have to be a cylinder; for example, it can be a polygonal cylinder with a polygonal cross-section. Please refer to [reference needed]. Figure 6 It can be seen in Figure 6 In the embodiment shown, the cross-section of the outer shell 121 is basically square (except that the sides are curved and the sides are connected by curved chamfers).

[0076] The aforementioned axis refers to the axis of the cylindrical portion. Coaxiality also means that the axes of the cylindrical portions are the same. However, having the same axis does not mean that the axes completely coincide; they can simply be parallel.

[0077] One of the limiting protrusion 15 and the limiting groove 16 is located on the inner side of the bracket 122, and the other is located on the outer side of the fixing member 14. Therefore, the engagement between the fixing member 14 and the bracket 122 occurs on the inner side of the bracket 122, without interfering with the outer shell 121. This allows for more flexible design choices for the outer shell 121. This is because the material requirements for the bracket 122, which provides support and limitation, may differ from those for the outer shell 121. For example, the material requirements for the bracket 122 may primarily emphasize higher strength, sufficient smoothness, and high wear resistance, while the outer shell 121 may require a better appearance or better heat dissipation, which may necessitate specific coloring properties and thermal conductivity requirements for the outer shell 121.

[0078] The fastener 14 cooperates with the bracket 122 without interfering with the outer shell 121, which allows for greater freedom in the selection of materials for the bracket 122 and the outer shell 121, making them more suitable for their respective application scenarios.

[0079] Furthermore, since the cylindrical part of the fixing member 14 cooperates with the cylindrical part of the bracket 122, it can also prevent the fixing member 14 from rotating relative to the housing 12. The axis of rotation here is along the radial direction of the bracket 122, which further reduces the wobbling of the lens 13.

[0080] Please refer to Figure 2 and Figure 6 In some embodiments, the fastener 14 includes a first mating portion 141 and a second mating portion 142 connected to each other and both being cylindrical; the second mating portion 142 is coaxially disposed within the first mating portion 141; the radially inner side of the first mating portion 141 mates with the radially outer side of the bracket 122, and the radially outer side of the second mating portion 142 mates with the radially inner side of the bracket 122.

[0081] In the above embodiment, the fixing member 14 has two cylindrical parts. The fitting structure of the limiting protrusion 15 and the limiting groove 16 is provided on the outer side of the second fitting part 142 and the inner side of the bracket 122. At the same time, the outer side of the second fitting part 142 fits with the inner side of the bracket 122, and the inner side of the first fitting part 141 also fits with the outer side of the bracket 122. Thus, there are at least three fitting relationships between the bracket 122 and the fixing member 14: the first fitting part 141 and the bracket 122, the second fitting part 142 and the bracket 122, and the fitting of the limiting protrusion 15 and the limiting groove 16. This further prevents the fixing member 14 from shaking relative to the bracket 122 (i.e., the housing 12), thereby improving the stability of the lens 13.

[0082] The meanings of "cylindrical" and "coaxial" mentioned above can be found in the text above.

[0083] Please refer to Figure 2 and Figure 6 In some embodiments, the bracket 122 includes a cylindrical portion 1221 and an abutment portion 1222. The abutment portion 1222 is disposed on the radially outer side of the cylindrical portion 1221. The axial direction of the cylindrical portion 1221 is the same as the light emission direction of the light source 11. The abutment portion 1222 is polygonal in cross-section perpendicular to the axial direction of the cylindrical portion 1221. The radially inner side of the first mating portion 141 abuts against the abutment portion 1222.

[0084] Figure 6 The cross section shown is for Figure 6 In the illustrated embodiment, this refers to the cross-section perpendicular to the axial direction of the cylindrical portion 1221. It can be seen that... Figure 6 In the embodiment shown, the abutment portion 1222 is quadrilateral. It can be seen that the quadrilateral in the figure is not a standard quadrilateral; its sides are curved, and the sides are connected by curved chamfers. Therefore, "polygonal" does not mean it is a regular polygon, but could also be a polygon-like shape.

[0085] In other embodiments, the polygon can be a triangle, pentagon, or hexagon, etc., and the edges of the polygon can be arcs, polygonal lines, straight lines, or free curves; the edges can also be connected by arcs, polygonal lines, straight lines, or free curves, or it is considered that any form of chamfer can be set between the edges. Furthermore, refer to... Figure 7 and Figure 9 You can intuitively see it from a three-dimensional perspective. Figure 7 The embodiment shown has the shape of the contact portion 1222.

[0086] Regardless of the polygon's shape, because it is non-circular, when the radially inner side of the first mating part 141 abuts against the abutting part 1222 (i.e., the first mating part 141 is fitted onto the outer side of the abutting part 1222), the abutting part 1222 can prevent the first mating part 141, i.e., the fixing member 14, from rotating around the axis of the light-emitting direction of the light source 11. This further limits the position of the lens 13, preventing the lens 13 from shaking.

[0087] Please refer to Figure 2 , Figure 6 and Figure 11 In some embodiments, the first mating part 141 is provided with an abutting rib 1411 on its radial inner side. The abutting rib 1411 is strip-shaped, and the length direction of the abutting rib 1411 is the same as the light emission direction of the light source 11.

[0088] The abutting rib 1411 is provided so that the abutting part between the first mating part 141 and the abutting part 1222 is the abutting rib 1411. The contact area between the strip-shaped abutting rib 1411 and the abutting part 1222 is small, so the abutting rib 1411 is easy to undergo elastic deformation under the pressure of the abutting part 1222.

[0089] Because there are certain errors in the manufacturing of components, namely manufacturing tolerances, when the abutting rib 1411 as a whole is interference-fitted with the abutting part 1222, the interference amount between different abutting ribs 1411 and the abutting part 1222 may be different. The abutting rib 1411 with a larger interference amount can undergo a greater degree of elastic deformation, so that the abutting ribs 1411 around the abutting rib 1411 with smaller interference amount can also abut with the abutting part 1222 and will not be "suspended". Therefore, the setting of the abutting rib 1411 can make the first mating part 141 and the abutting part 1222 fit more tightly.

[0090] Of course, in other embodiments, when the bracket 122 does not have an abutment portion 1222, the abutment rib 1411 can directly abut against other parts of the bracket 122 and achieve the same effect.

[0091] The length direction of the abutting rib 1411 is the same as the light emission direction of the light source 11, and it can also play a certain guiding role. When the abutting rib 1411 deforms, the abutting part 1222 will also be pressed into a dent by the abutting rib 1411 (it may be elastic deformation, that is, the dent disappears after the abutting rib 1411 is removed; it may also be plastic deformation, that is, the dent can still be retained after the abutting rib 1411 is removed). In this way, the dent and the abutting rib 1411 form a fit, providing guidance for the movement of the fixing part 14 and increasing the stability of the lens 13.

[0092] Please refer to Figure 2In some embodiments, the lighting assembly 10 further includes a damping ring 17, which is fitted on the radially outer side of the fixing member 14 and abuts against the radially inner side of the bracket 122.

[0093] The damping ring 17 can prevent relative movement between the fixing member 14 and the bracket 122, that is, provide damping force, ensuring the stability of the positional relationship between the bracket 122 and the fixing member 14 after the position of the lens 13 is adjusted. In addition, the damping ring 17 can also provide damping force during the adjustment process, making the positional change between the fixing member 14 and the bracket 122 more linear and improving the accuracy of adjustment.

[0094] The damping force between the fastener 14 and the bracket 122 can also be adjusted by adjusting the interference fit between the damping ring 17 and the bracket 122. Specifically, when a greater damping force is required, the interference fit between the damping ring 17 and the bracket 122 can be increased. The damping ring 17 can be made of flexible materials such as silicone or rubber, so that it can maintain an interference fit with the bracket 122 through its own elasticity during continuous wear.

[0095] Please refer to Figure 2 In some embodiments, a ring rib 1442 may be provided around the outer side of the second clamping member 144. Two ring ribs 1442 may be provided at intervals along the axial direction of the second clamping member 144, and the damping ring 17 is limited in the two ring ribs 1442. A limiting ring 1223 may also be provided around the inner side of the bracket 122. The ring rib 1442 may also be used to abut against the limiting ring 1223 to prevent the fixing member 14 from sliding out of the housing and causing the fixing member 14 to fall off.

[0096] Please refer to Figure 2 and Figure 7 In some embodiments, the fixing member 14 includes a first clamping member 143 and a second clamping member 144 connected to each other; the first clamping member 143 abuts against the light-emitting side of the lens 13, and the second clamping member 144 abuts against the light-incident side of the lens 13 to clamp the lens 13.

[0097] Since the lens 13 moves in the same direction as the light emitting direction of the light source 11, and the optical axis of the lens 13 is usually along the light emitting direction of the light source 11, the lens 13 is mostly subjected to force in the direction along its own optical axis. The first clamping member 143 and the second clamping member 144 clamp the lens 13 on the light emitting side and the light emitting side, that is, limit the lens 13 on both sides in the optical axis direction, which can improve the stability of the lens 13.

[0098] The first clamping member 143 and the second clamping member 144 can be connected by screwing, bonding or interference fit.

[0099] It should be noted that the first clamping member 143 and the second clamping member 144, as well as the first mating part 141 and the second mating part 142, do not have a strict correspondence. Please refer to [the relevant documentation]. Figure 2 ,exist Figure 2 In the illustrated embodiment, the first mating portion 141 is a part of the outer side of the first clamping member 143, while the second mating portion 142 is a part of the inner side of the first clamping member 143 and the entire second clamping member 144. In other embodiments, the first mating portion 141 may be the entire first clamping member 143, and the second mating portion 142 may be the entire second clamping member 144; or the first mating portion 141 may be a part of the first clamping member 143 and the second clamping member 144, while the second mating portion 142 may be another part of the second clamping member 144.

[0100] Please refer to Figure 1 and Figure 4 ,or Figure 8 and Figure 10 In some embodiments, the first clamping member 143 and the second clamping member 144 are snapped together.

[0101] In this way, the first clamping member 143 and the second clamping member 144 can be inserted to complete the connection between them and fix the lens 13, making the installation of the lighting assembly 10 easier and improving the production efficiency of the lighting assembly 10.

[0102] exist Figure 4 In the illustrated embodiment, a female snap-fit ​​portion 1432 is provided on the first clamping member 143, and a male snap-fit ​​portion 1443 is provided on the second clamping member 144. The female snap-fit ​​portion 1432 and the male snap-fit ​​portion 1443 cooperate to achieve a snap-fit ​​connection between the first clamping member 143 and the second clamping member 144. In other embodiments, a male snap-fit ​​portion 1443 may also be provided on the first clamping member 143, and a female snap-fit ​​portion 1432 may be provided on the second clamping member 144.

[0103] Please refer to Figure 7 , Figure 8 and Figure 10 It can be seen that multiple male buckle portions 1443 and female buckle portions 1432 can be provided, and they can be distributed at intervals in the circumferential direction of the first clamping member 143 and the second clamping member 144 to ensure a reliable snap-fit ​​connection.

[0104] Please refer to Figure 3 and Figure 6 ,or Figure 10 and Figure 11In some embodiments, one of the first clamping member 143 and the second clamping member 144 is provided with an anti-rotation rib 1441, and the other of the first clamping member 143 and the second clamping member 144 is provided with an anti-rotation groove 1431; both the anti-rotation rib 1441 and the anti-rotation groove 1431 are strip-shaped, and the length direction of both the anti-rotation rib 1441 and the anti-rotation groove 1431 is the same as the optical axis direction of the lens 13; the anti-rotation rib 1441 and the anti-rotation groove 1431 cooperate.

[0105] Since the length direction of both the anti-rotation rib 1441 and the anti-rotation groove 1431 is the same as the optical axis direction of the lens 13, the anti-rotation rib 1441 and the anti-rotation groove 1431 are both along the direction of movement when the first clamping member 143 and the second clamping member 144 are interlocked. Therefore, the anti-rotation rib 1441 and the anti-rotation groove 1431 can provide a guiding function when the first clamping member 143 and the second clamping member 144 are installed.

[0106] In some embodiments, the first clamping member 143 and the second clamping member 144 may not be connected by a snap-fit ​​connection. In this case, the anti-rotation rib 1441 and the anti-rotation groove 1431 can still play a limiting role (in embodiments with snap-fit ​​connections, they can also play a limiting role). That is, they prevent the first clamping member 143 and the second clamping member 144 from rotating relative to each other around the optical axis of the lens 13. Therefore, the anti-rotation rib 1441 and the anti-rotation groove 1431 can ensure the stability of the installation environment of the lens 13, thereby improving the stability of the lens 13.

[0110] The universal joint 30 connects the lighting component 10 and the lamp holder 20, making it easy to adjust the angle of the lighting component 10 relative to the lamp holder 20 for convenient use.
