Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an integrally formed extruded lens assembly, optical system and lamp. Background Technology

[0002] In LED lighting manufacturing, light control structures are often used to control the light beam emitted by the LED light source to meet specific application needs. Light control structures can be light-transmitting components such as convex lenses and concave lenses. By adjusting the direction of light propagation through concave and convex lenses, a light beam that meets specific needs can be formed. However, the light control effect of a single light control structure is often limited and cannot achieve the required optical effect. Therefore, multiple light control structures are often used in actual optical structures to control light in combination. Multiple light control structures require multiple mounting components for fixation, which increases the installation difficulty and occupies a large volume, making the lamp bulky. Utility Model Content

[0003] The purpose of this invention is to overcome the problem in the prior art that multiple light control structures require multiple mounting components for fixation, which increases the installation difficulty, and to provide an integrally molded extruded lens assembly, optical system and lamp.

[0004] In a first aspect, the present invention provides an integrally formed extruded lens assembly, comprising an integrally formed first light-controlling structure, a second light-controlling structure, and a connecting edge, wherein the first light-controlling structure, the second light-controlling structure, and the connecting edge enclose and form an inner cavity.

[0005] The first light-controlling structure, the second light-controlling structure, and the inner cavity all extend along a first direction;

[0006] The first light control structure and the second light control structure are opposite to each other and spaced apart;

[0007] The first light control structure, the second light control structure, and the connecting edge are integrally formed using a two-color extrusion process.

[0008] This utility model provides an integrally molded extruded lens assembly. The light is adjusted sequentially by a first light-controlling structure and a second light-controlling structure that are arranged opposite to each other and spaced apart. This helps to enhance the overall light control capability of the lens assembly and improve the light output effect. The first light-controlling structure, the second light-controlling structure and the connecting edge are integrally molded and the three of them enclose an inner cavity. This simplifies the manufacturing process and reduces the manufacturing cost. It can also eliminate the need for additional installation structures to reduce the difficulty and cost of installation. Furthermore, it can reduce the volume and enable the lens assembly itself to have high strength so as to maintain the stability of the relative position of the two light-controlling structures during use.

[0009] Preferably, the first light control structure includes a light-transmitting part located in the middle and light-shielding parts located on both sides, wherein the light-transmitting part is made of a light-transmitting material and the light-shielding parts are made of an opaque material.

[0010] Preferably, the cross-sectional width of the light-transmitting portion is smaller than the cross-sectional width of the second light-controlling structure.

[0011] Preferably, the light-transmitting part is a convex lens structure.

[0012] Preferably, the curvature of the light-transmitting portion on the side closer to the inner cavity is greater than the curvature on the side farther from the inner cavity.

[0013] Those skilled in the art will understand that the light control of a lens structure is mainly achieved through the refractive index difference between different media, such as the refractive index difference between the light-transmitting part and the air as mentioned above. The interface that plays the main role in light control is the interface between the surface on the side with large curvature and the air. In the LED field, the farther the LED bead is from the surface on the side with large curvature, the longer the optical path of the light, and the better the light control effect of the lens structure. Therefore, making the curvature of the side of the light-transmitting part closer to the inner cavity greater than the curvature of the side farther from the inner cavity is beneficial to increasing the optical path and improving the light output effect.

[0014] Preferably, the first light-controlling structure has a groove on the side away from the inner cavity, and the groove corresponds to the light-transmitting part.

[0015] Preferably, the second light control structure is a convex lens structure or a Fresnel lens structure.

[0016] Preferably, the second light control structure is a Fresnel lens structure, and the side of the second light control structure closest to the inner cavity is a Fresnel surface, while the side of the second light control structure away from the inner cavity is a plane.

[0017] Preferably, the second light control structure is a Fresnel lens structure, and the side of the second light control structure away from the inner cavity is a Fresnel surface, while the side of the second light control structure closer to the inner cavity is a plane.

[0018] Preferably, the second light control structure is a Fresnel lens structure, and both sides of the second light control structure are Fresnel surfaces.

[0019] Preferably, the connecting edge includes a first connecting edge and a second connecting edge distributed on both sides of the inner cavity, and both the first connecting edge and the second connecting edge are made of opaque material.

[0020] Preferably, the first light-controlling structure, the second light-controlling structure, and the connecting edge are all made of silicone.

[0021] In a second aspect, the present invention provides an optical system including a light source and an integrally formed extruded lens assembly as described above, wherein the light source is located on the side of the first light control structure away from the inner cavity; the light source includes LED beads.

[0022] In a third aspect, the present invention provides a lamp, including the integrally formed extruded lens assembly as described above.

[0023] In a fourth aspect, the present invention provides a lamp that includes the optical system described above.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This utility model provides an integrally molded extruded lens assembly. The light is adjusted sequentially by a first light-controlling structure and a second light-controlling structure that are arranged opposite to each other and spaced apart. This helps to enhance the overall light control capability of the lens assembly and improve the light output effect. The first light-controlling structure, the second light-controlling structure and the connecting edge are integrally molded and the three of them enclose an inner cavity. This simplifies the manufacturing process and reduces the manufacturing cost. It can also eliminate the need for additional installation structures to reduce the difficulty and cost of installation. Furthermore, it can reduce the volume and enable the lens assembly itself to have high strength so as to maintain the stability of the relative position of the two light-controlling structures during use.

[0049] Example 1

[0050] like Figures 1 to 8 As shown, this embodiment provides an integrally formed extruded lens assembly, including an integrally formed first light control structure 1, a second light control structure 2, and a connecting edge. The first light control structure 1, the second light control structure 2, and the connecting edge enclose an inner cavity 5. The first light control structure 1, the second light control structure 2, and the inner cavity 5 all extend along a first direction. The first light control structure 1 and the second light control structure 2 are opposite to each other and spaced apart.

[0051] The lens assembly may be a strip-shaped member extending along a first direction, which is the length direction of the lens assembly; the first direction may be a straight line or a curved line. For example, the lens assembly may be made of a flexible material that allows it to bend, and in the bent state, the first direction is a curved line.

[0052] The lens assembly includes a first light-controlling structure 1, a second light-controlling structure 2, and a connecting edge, such as... Figure 1 As shown, the connecting edge connects the first light control structure 1 and the second light control structure 2, and the three together form an inner cavity 5. In terms of spatial structure, the inner cavity 5 extends along the first direction, and the inner cavity 5 separates the first light control structure 1 and the second light control structure 2. When light passes through the lens assembly from the outside, the light first passes through one light control structure, then through the inner cavity 5, and finally through the other light control structure.

[0053] Both the first light control structure 1 and the second light control structure 2 can adjust the light to change the propagation direction of the transmitted light. The first light control structure 1 and the second light control structure 2 are arranged opposite to each other so that the light transmitted from the first light control structure 1 can illuminate the second light control structure 2 and then be transmitted out from the second light control structure 2.

[0054] The light transmitted from the first light-controlling structure 1 passes through the inner cavity 5 and then shines on the second light-controlling structure 2. By adjusting the size of the inner cavity 5, the light can be dispersed as much as possible to the side of the second light-controlling structure 2 near the inner cavity 5, thereby giving full play to the light control capability of the second light-controlling structure 2.

[0055] For example, during the light transmission process, external light first passes through the first light-controlling structure 1, then through the inner cavity 5, and finally through the second light-controlling structure 2. By reasonably adjusting the size of the inner cavity 5, that is, changing the distance between the first light-controlling structure 1 and the second light-controlling structure 2, or changing the width of the second light-controlling structure 2, the light adjusted by the first light-controlling structure 1 can be dispersed as much as possible to illuminate the side of the second light-controlling structure 2 near the inner cavity 5, thereby making full use of the light-adjusting effect of the second light-controlling structure 2.

[0056] In the above usage, the light-emitting side of the first light-controlling structure 1 is opposite to the light-incoming side of the second light-controlling structure 2, and the external light source 6 can be set on the side of the first light-controlling structure 1 away from the second light-controlling structure 2. The second light-controlling structure 2 can receive the light transmitted from the first light-controlling structure 1.

[0057] Preferably, the first light-controlling structure 1, the second light-controlling structure 2, and the connecting edge are manufactured using an extrusion process; more preferably, the first light-controlling structure 1, the second light-controlling structure 2, and the connecting edge are integrally formed using a two-color extrusion process.

[0058] Therefore, the integrally formed extruded lens assembly provided in this embodiment adjusts the light sequentially through a first light-controlling structure and a second light-controlling structure that are arranged relative to each other and spaced apart. This helps to enhance the overall light control capability of the lens assembly and improve the light output effect. The first light-controlling structure, the second light-controlling structure, and the connecting edge are integrally formed and enclosed to form an inner cavity. This simplifies the manufacturing process and reduces manufacturing costs. It also eliminates the need for additional installation structures to reduce installation difficulty and costs, reduces volume, and enables the lens assembly itself to have high strength so as to maintain the stability of the relative positions of the two light-controlling structures during use.

[0059] This embodiment uses a two-color extrusion process to integrally form the first light-controlling structure 1, the second light-controlling structure 2, and the connecting edge, which can create a first light-controlling structure 1 and a second light-controlling structure 2 that are transparent or partially transparent, and a connecting edge that is opaque. It has the advantages of simple manufacturing, convenient installation, small size, and good optical effect.

[0060] Preferably, the first light-controlling structure 1, the second light-controlling structure 2, and the connecting edge are all made of silicone.

[0061] In some embodiments, the first light control structure 1 includes a light-transmitting part 13 located in the middle and light-shielding parts 12 located on both sides. The light-transmitting part 13 is made of a light-transmitting material, and the light-shielding parts 12 are made of an opaque material.

[0062] like Figure 1 As shown, the light-transmitting part 13 allows light to pass through and can adjust the propagation direction of the transmitted light; the light-transmitting part 13 can be made of a light-transmitting material, such as a transparent or translucent material.

[0063] Light-shielding parts 12 are provided on both sides of the light-transmitting part 13. The light-shielding parts 12 can be made of opaque material. The light-shielding parts 12 can reduce the leakage of light transmitted through the light-transmitting part 13 from the first light-controlling structure 1. The light-shielding parts 12 are part of the first light-controlling structure 1. The light-shielding parts 12 serve to connect the light-transmitting part 13 and the first connecting edge 3, or to connect the light-transmitting part 13 and the second connecting edge 4.

[0064] Preferably, the cross-sectional width of the light-transmitting portion 13 is smaller than the cross-sectional width of the second light-controlling structure 2.

[0065] The cross-sectional width refers to the left and right width of the lens assembly's cross-section, with the left and right directions being... Figure 1 The direction from the first connecting edge 3 to the second connecting edge 4, or the direction from the second connecting edge 4 to the first connecting edge 3. The cross-sectional width of the second light-controlling structure 2 is greater than the cross-sectional width of the light-transmitting part 13, so that the second light-controlling structure 2 can receive the diverging light beam transmitted from the light-transmitting part 13 more fully, which is beneficial to improving the utilization rate of light.

[0066] For example, in the preferred usage, the divergent beam emitted by the light source 6 is transformed into a divergent beam with a smaller beam angle after passing through the first light control structure 1. This divergent beam with a smaller beam angle propagates a distance in the inner cavity 5, and its light distribution range is further increased, so that the light distribution area illuminating the second light control structure 2 is larger than the light distribution area on the first light control structure 1. In order to better receive light, the cross-sectional width of the second light control structure 2 is designed to be larger.

[0067] This embodiment defines a second direction, which is parallel to the cross-section of the lens assembly and approximately parallel to the direction from the first light-controlling structure 1 to the second light-controlling structure 2. Figure 1 As shown.

[0068] In the projection in the second direction, the width of the first light control structure 1 is smaller than the width of the second light control structure 2.

[0069] Preferably, the second light-controlling structure 2 is made of a light-transmitting material, such as a transparent or translucent material.

[0070] In some embodiments, the light-transmitting part 13 is a convex lens structure; by converging the light through the convex lens structure, the beam angle of the incident beam can be reduced, allowing more light to illuminate the second light control structure 2.

[0071] Preferably, the curvature of the light-transmitting portion 13 on the side closer to the inner cavity 5 is greater than the curvature of the side farther from the inner cavity 5.

[0072] In the preferred usage, the side of the light-transmitting part 13 away from the inner cavity 5 is the light-incident side, and the side closer to the inner cavity 5 is the light-exiting side. Those skilled in the art will understand that the light control of the lens structure is mainly achieved through the refractive index difference between different media, such as the refractive index difference between the light-transmitting part 13 and air. The interface that plays the main role in light control is the interface between the surface of the light-transmitting part 13 with large curvature and the air. In the LED field, the farther the LED bead is from the surface with large curvature, the longer the optical path of the light, and the better the light control effect of the lens structure. Therefore, making the curvature of the side of the light-transmitting part 13 closer to the inner cavity 5 greater than the curvature of the side away from the inner cavity 5 is beneficial to increase the optical path and improve the light output effect.

[0073] Furthermore, by reducing the curvature of the surface of the light-transmitting part 13 away from the inner cavity 5, the height of the light-transmitting part 13 protruding outward can be reduced, which is beneficial to reducing the size of the lens assembly. When the light source 6 is installed outside the first light control structure 1, the surface with a small curvature blocks less light than the surface with a large curvature, which allows the light source 6 to be arranged in a position closer to the first light control structure 1, which is beneficial to reducing the overall volume of the lamp.

[0074] More preferably, the light-transmitting part 13 is a plano-convex lens structure with one side protruding and the other side flat, and the protruding side is close to the inner cavity 5, while the flat side is far away from the inner cavity 5.

[0075] More preferably, the light-shielding part 12 is a strip-shaped plate.

[0076] Preferably, the first light-controlling structure 1 has a groove 11 on the side away from the inner cavity 5, and the groove 11 corresponds to the light-transmitting part 13.

[0077] The bottom surface of the groove 11 is lower than the outer surface of the first light control structure 1, and the groove 11 can extend along the first direction; the light source 6, such as an LED lamp bead, can be arranged in the groove 11, and the groove 11 forms a space to accommodate the light source 6, so that the outer surface of the first light control structure 1 can be attached to the mounting structure such as the base and the lamp board, which helps to reduce the relative shaking of the light source 6 and the lens assembly during use and improve the stability of the illumination.

[0078] For example, LED beads can be set on the lamp board. During installation, the lamp board and the groove 11 enclose each other to form a strip cavity. The LED beads are located in the strip cavity. The outer surface of the first light control structure 1 can be attached to the lamp board to achieve a stable installation.

[0079] The groove 11 corresponds to the light-transmitting part 13, so that the light emitted by the light source 6 arranged in the groove 11 can be transmitted through the light-transmitting part 13; more preferably, the central axis of the groove 11 coincides with the central axis of the light-transmitting part 13.

[0080] Preferably, the connecting edge includes a first connecting edge 3 and a second connecting edge 4 distributed on both sides of the inner cavity 5, and both the first connecting edge 3 and the second connecting edge 4 are made of opaque material.

[0081] like Figure 1 As shown, the first connecting edge 3 and the second connecting edge 4 are distributed on the left and right sides of the inner cavity 5. The first connecting edge 3 connects to the left side of the first light control structure 1 and the second light control structure 2, and the second connecting edge 4 connects to the right side of the first light control structure 1 and the second light control structure 2. Through the connection and support of the first connecting edge 3 and the second connecting edge 4 on the left and right sides, not only can the relative position of the first light control structure 1 and the second light control structure 2 be kept stable, but also only a few fixing structures are needed to fix the lens assembly to the lamp as a whole.

[0082] Both the first connecting edge 3 and the second connecting edge 4 are made of opaque material, which can reduce the escape of light and reduce the damage of light leakage to the overall aesthetics.

[0083] More preferably, the first light-controlling structure 1 and the second light-controlling structure 2 are parallel to each other; the first connecting edge 3 and the second connecting edge 4 are parallel to each other; the first light-controlling structure 1 is perpendicular to the first connecting edge 3; in the above structure, the first light-controlling structure 1, the second light-controlling structure 2 and the connecting edge are approximately rectangularly distributed.

[0084] Preferably, the cross-sectional width of the second light-controlling structure 2 is equal to or approximately equal to the distance between the first connecting edge 3 and the second connecting edge 4.

[0085] In some embodiments, the second light control structure 2 is a convex lens structure; in other embodiments, the second light control structure 2 is a Fresnel lens structure.

[0086] A convex lens structure refers to an optical structure similar to a convex lens, and a Fresnel lens structure refers to an optical structure similar to a Fresnel lens. Both convex lenses and Fresnel lenses can converge light rays, thereby further adjusting the beam transmitted from the first light control structure 1 to obtain better optical effects.

[0087] Preferably, the second light control structure 2 is a convex lens structure, and the curvature of the side of the second light control structure 2 away from the inner cavity 5 is greater than the curvature of the side of it close to the inner cavity 5.

[0088] The side of the second light control structure 2 closest to the inner cavity 5 is the light-incident side. Setting it to a surface with a small curvature can reduce the obstruction of light and make the light more evenly distributed on the surface of the light-incident side of the second light control structure 2. The side away from the inner cavity 5 is the light-exit side. Setting it to a surface with a large curvature is beneficial to increase the optical path and improve the light output effect.

[0089] More preferably, the second light control structure 2 is a plano-convex lens structure with one side convex and the other side flat, with the convex side away from the inner cavity 5 and the flat side close to the inner cavity 5.

[0090] Preferably, the second light control structure 2 is a Fresnel lens structure; and in the first embodiment: the side of the second light control structure 2 closest to the inner cavity 5 is a Fresnel surface, and the side of the second light control structure 2 away from the inner cavity 5 is a plane.

[0091] The Fresnel lens described in this embodiment is a strip-shaped Fresnel lens that extends along the first direction. The Fresnel surface is a surface with several raised strips. Arranging the Fresnel surface on the side close to the inner cavity 5 can make the outer surface of the second light control structure 2 flatter, which helps to reduce damage to the Fresnel lens during installation and use.

[0092] In the second embodiment: the side of the second light control structure 2 away from the inner cavity 5 is a Fresnel surface, and the side of the second light control structure 2 closer to the inner cavity 5 is a plane.

[0093] In the third implementation: both sides of the second light control structure 2 are Fresnel surfaces.

[0094] By setting both sides as Fresnel surfaces, the light-converging effect of the second light-controlling structure 2 can be increased under the condition that the height of the raised strip is limited.

[0095] Preferably, the second light control structure 2 has a Fresnel surface on one side and a sawtooth surface on the other side, with the sawtooth surface having several strip-shaped sawtooth protrusions; the sawtooth surface can meet specific lighting needs.

[0096] In some embodiments, the lens assembly is symmetrically arranged about the symmetry plane 7, which passes through the central axis of the first light control structure 1 and the second light control structure 2; the symmetrical arrangement can improve the uniformity of the left and right light rays and also simplify the manufacturing process.

[0099] Preferably, the light source 6 is oriented toward the first light control structure 1; more preferably, the light source 6 is oriented toward the light-transmitting part 13.

[0100] Preferably, the light source 6 is an LED lamp bead, and a plurality of LED lamp beads are arranged along the first direction.
