Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to an integrally formed extruded lens assembly, an optical system, and a lamp. Background Art

[0002] In the manufacture of LED lamps, light control structures are often used to control the light beam emitted by the LED light source to meet specific usage needs. The light control structure can be a convex lens, a concave lens or other light-transmitting parts. The propagation direction of the light can be adjusted by the convex and concave lenses to form a light beam that meets specific needs. 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 cooperate with light control. Multiple light control structures require multiple mounting structures to achieve fixation, which increases the difficulty of installation and also occupies a large volume, making the lamp body bloated. Summary of the Invention

[0003] The purpose of the present invention is to overcome the problem in the background art that multiple light control structures require multiple mounting structures to be fixed, which increases the difficulty of installation, and to provide an integrally formed 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-control structure, a second light-control structure, and a connecting edge, wherein the first light-control structure, the second light-control structure, and the connecting edge enclose an inner cavity; The first light-controlling structure, the second light-controlling structure and the inner cavity all extend along a first direction; The first light-controlling structure and the second light-controlling structure are arranged opposite to each other and spaced apart; The first light-controlling structure, the second light-controlling structure and the connecting edge are integrally formed by a two-color extrusion process.

[0005] The present invention provides an integrally formed extruded lens assembly, which adjusts light in sequence through a first light-controlling structure and a second light-controlling structure that are relatively and spaced apart, thereby enhancing the overall light-controlling ability of the lens assembly and improving the light-emitting effect; the first light-controlling structure, the second light-controlling structure and the connecting edge are integrally formed and the three are enclosed to form an inner cavity, which can simplify the manufacturing process to reduce the manufacturing cost, eliminate the need for additional mounting structures to reduce the difficulty and cost of installation, reduce the volume, and enable the lens assembly itself to have higher strength to maintain the stability of the relative positions of the two light-controlling structures during use.

[0006] Preferably, the first light-control structure includes a light-transmitting portion in the middle and light-shielding portions on both sides, the light-transmitting portion is made of a light-transmitting material, and the light-shielding portions are made of an opaque material.

[0010] 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 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 lamp 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, the curvature of the light-transmitting part close to the inner cavity is greater than the curvature on the side away from the inner cavity, which is conducive to increasing the optical path and improving the light output effect.

[0012] Preferably, the second light-controlling structure is a convex lens structure or a Fresnel lens structure.

[0013] Preferably, the second light-controlling structure is a Fresnel lens structure, and a side of the second light-controlling structure close to the inner cavity is a Fresnel surface, and a side of the second light-controlling structure away from the inner cavity is a plane.

[0014] Preferably, the second light-controlling structure is a Fresnel lens structure, and a side of the second light-controlling structure away from the inner cavity is a Fresnel surface, and a side of the second light-controlling structure close to the inner cavity is a flat surface.

[0024] The present invention will be further described in detail below with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments, as all technologies implemented based on the present invention fall within the scope of the present invention.

[0025] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating the orientation or positional relationship, such as "upper", "lower", "left", "right", "center", "inside", and "outside", are based on the expressions of the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the invented product / device / apparatus is placed when it is conventionally used. These terms of orientation or positional relationship are merely for the purpose of facilitating the description of the scheme of the present invention or simplifying the description of the specific embodiments to facilitate the rapid understanding of the scheme by technicians, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship, and therefore should not be understood as limiting the present invention.

[0026] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly tilted. Alternatively, it can be simply understood that the corresponding devices / components / elements are set in directions such as "horizontal", "vertical", "overhanging", and "parallel", and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the present invention.

[0027] In addition, the expressions “first”, “second”, “third”, etc. in the terms are merely used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of specific components.

[0028] In addition, in the description of the embodiments of the present invention, "several," "plurality," and "a number" represent at least two. It can also be any number such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0029] Furthermore, in the description of the technical solution of the present invention, unless otherwise expressly specified, defined, or limited, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welded, riveted, bolted, threaded, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communicative; they may be direct, indirect via an intermediate medium, or internally connected between two components.

[0030] Example 1 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, and the first light-control structure 1 and the second light-control structure 2 are arranged opposite to each other and at intervals.

[0031] The lens assembly can be a strip-shaped component extending along a first direction, where the first direction is the length direction of the lens assembly; the first direction can be a straight direction or a curved direction, for example: the lens assembly can be made of a flexible material so that it can be bent, and in the bent state, the first direction is a curved direction.

[0032] The lens assembly includes a first light control structure 1, a second light control structure 2 and a connecting edge. Figure 1 As shown, the connecting edge connects the first light-control structure 1 and the second light-control structure 2, and the three enclose 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 passes through the inner cavity 5, and finally passes through the other light-control structure.

[0033] 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 relative to each other, so that the light transmitted from the first light-control structure 1 can be irradiated on the second light-control structure 2 and further transmitted out from the second light-control structure 2.

[0034] The light transmitted from the first light-controlling structure 1 passes through the inner cavity 5 and then irradiates 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 irradiate the side of the second light-controlling structure 2 close to the inner cavity 5, thereby giving full play to the light-controlling ability of the second light-controlling structure 2.

[0035] For example: during the light transmission process, external light first passes through the first light-control structure 1, then through the inner cavity 5, and finally through the second light-control structure 2; by reasonably adjusting the size of the inner cavity 5, that is, changing the spacing between the first light-control structure 1 and the second light-control structure 2, or changing the width of the second light-control structure 2, the light adjusted by the first light-control structure 1 can be dispersed as much as possible to illuminate the side of the second light-control structure 2 close to the inner cavity 5, thereby fully utilizing the light adjustment effect of the second light-control structure 2.

[0036] In the above usage, the light-emitting side of the first light-control structure 1 is opposite to the light-incoming side of the second light-control structure 2 , and the external light source 6 can be arranged on the side of the first light-control structure 1 away from the second light-control structure 2 , and the second light-control structure 2 can receive light transmitted from the first light-control structure 1 .

[0037] Preferably, the first light-control structure 1 , the second light-control structure 2 and the connecting edge are made by an extrusion process; further preferably, the first light-control structure 1 , the second light-control structure 2 and the connecting edge are integrally formed by a two-color extrusion process.

[0038] Therefore, the present embodiment provides an integrally formed extruded lens assembly, which adjusts the light in sequence through the first light-controlling structure and the second light-controlling structure that are relatively and spaced apart, thereby enhancing the overall light-controlling ability of the lens assembly and improving the light-emitting effect; the first light-controlling structure, the second light-controlling structure and the connecting edge are integrally formed and the three are enclosed to form an inner cavity, which can simplify the manufacturing process to reduce the manufacturing cost, eliminate the additional mounting structure to reduce the installation difficulty and cost, reduce the volume, and enable the lens assembly itself to have higher strength to maintain the stability of the relative positions of the two light-controlling structures during use.

[0039] This embodiment adopts a two-color extrusion process to integrally form the first light-control structure 1, the second light-control structure 2 and the connecting edge, which can produce a first light-control structure 1 and a second light-control structure 2 that are translucent or partially translucent, and produce an opaque connecting edge, and has the advantages of simple production, easy installation, small volume and good optical effect.

[0040] Preferably, the first light-controlling structure 1 , the second light-controlling structure 2 and the connecting edge are all made of silicone.

[0041] In some embodiments, the first light-control structure 1 includes a light-transmitting portion 13 in the middle and light-shielding portions 12 on both sides. The light-transmitting portion 13 is made of a light-transmitting material, and the light-shielding portions 12 are made of an opaque material.

[0042] like Figure 1 As shown, the light-transmitting portion 13 allows light to pass through and can adjust the propagation direction of the light passing through. The light-transmitting portion 13 can be made of a light-transmitting material, such as a transparent or translucent material.

[0043] Light-shielding portions 12 are provided on both sides of the light-transmitting portion 13. The light-shielding portions 12 can be made of opaque material. The light-shielding portions 12 can reduce the light passing through the light-transmitting portion 13 from leaking out of the first light-controlling structure 1. The light-shielding portions 12 are part of the first light-controlling structure 1. The light-shielding portions 12 serve to connect the light-transmitting portion 13 and the first connecting edge 3, or to connect the light-transmitting portion 13 and the second connecting edge 4.

[0044] 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 .

[0045] The cross-sectional width refers to the left and right width of the lens component cross section. Figure 1 The direction of the second connecting edge 3 points to the second connecting edge 4, or the direction of the second connecting edge 4 points 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 portion 13, so that the second light-controlling structure 2 can more fully receive the divergent light beam transmitted from the light-transmitting portion 13, which is conducive to improving the utilization rate of light.

[0046] For example: In the preferred usage mode, the divergent light beam emitted by the light source 6 is transformed into a divergent light beam with a smaller beam angle after passing through the first light-control structure 1. The divergent light beam with a smaller beam angle propagates for a certain distance in the inner cavity 5, and the distribution range of its light is further increased, so that the light distribution area irradiated on 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.

[0047] 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 shown.

[0048] In the projection in the second direction, the width of the first light-controlling structure 1 is smaller than the width of the second light-controlling structure 2 .

[0049] Preferably, the second light-control structure 2 is made of a light-transmitting material, such as a transparent or translucent material.

[0050] In some embodiments, the light-transmitting portion 13 is a convex lens structure. By converging the light through the convex lens structure, the beam angle of the incident light beam can be reduced, so that more light can be irradiated onto the second light-controlling structure 2 .

[0051] Preferably, the curvature of the light-transmitting portion 13 on the side close to the inner cavity 5 is greater than the curvature of the light-transmitting portion 13 on the side away from the inner cavity 5 .

[0052] In the preferred usage mode, the side of the light-transmitting portion 13 away from the inner cavity 5 is the light-entering side, and the side close to the inner cavity 5 is the light-emitting side; those skilled in the art can 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 portion 13 and the air. The interface that plays the main role in light control is the interface between the surface of the large curvature side of the light-transmitting portion 13 and the air. In the LED field, the farther the LED lamp bead is from the surface of the large curvature side, 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 light-transmitting portion 13 close to the inner cavity 5 greater than the curvature of the side away from the inner cavity 5 is conducive to increasing the optical path and improving the light-emitting effect.

[0053] Moreover, by reducing the curvature of the surface of the light-transmitting portion 13 away from the inner cavity 5, the height of the outward protrusion of the light-transmitting portion 13 can be reduced, which is conducive to reducing the size of the lens assembly; when the light source 6 is installed on the outside of the first light-control structure 1, the surface with a small curvature blocks less light than the surface with a large curvature, so that the light source 6 can be arranged in a position closer to the first light-control structure 1, which is conducive to reducing the overall volume of the lamp.

[0054] Further preferably, the light-transmitting portion 13 is a plano-convex lens structure with one side convex and the other side flat, and the convex side is close to the inner cavity 5 and the flat side is far away from the inner cavity 5 .

[0055] Further preferably, the shading portion 12 is a strip-shaped plate.

[0056] Preferably, a groove 11 is provided on a side of the first light-control structure 1 away from the inner cavity 5 , and the groove 11 corresponds to the light-transmitting portion 13 .

[0057] 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 a space for accommodating the light source 6 is formed by the groove 11, so that the outer surface of the first light control structure 1 can be attached to the base, light board and other mounting structures, which is beneficial to reduce the relative shaking of the light source 6 and the lens assembly during use and improve the lighting stability.

[0058] For example: LED lamp beads can be set on the lamp board. During installation, the lamp board and the groove 11 are enclosed to form a strip cavity, and the LED lamp beads are located in the strip cavity. The outer surface of the first light control structure 1 can be abutted against the lamp board to achieve stable installation.

[0059] The groove 11 corresponds to the light-transmitting portion 13 , so that light emitted by the light source 6 arranged at the groove 11 can pass through the light-transmitting portion 13 ; further preferably, the central axis of the groove 11 coincides with the central axis of the light-transmitting portion 13 .

[0060] 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 the first connecting edge 3 and the second connecting edge 4 are both made of opaque material.

[0061] 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 the left sides of the first light-control structure 1 and the second light-control structure 2, and the second connecting edge 4 connects the right sides 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 maintained stable, but also only a small amount of fixing structure is required to fix the lens assembly as a whole to the lamp.

[0062] The first connecting edge 3 and the second connecting edge 4 are both made of opaque material, which can reduce the escape of light and reduce the damage to the overall aesthetics caused by light leakage.

[0063] Further preferably, the first light-control structure 1 and the second light-control 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-control structure 1 is perpendicular to the first connecting edge 3; in the above structure, the first light-control structure 1, the second light-control structure 2 and the connecting edges are approximately distributed in a rectangular shape.

[0064] 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 .

[0065] In some embodiments, the second light-controlling structure 2 is a convex lens structure; in other embodiments, the second light-controlling structure 2 is a Fresnel lens structure.

[0066] The convex lens structure refers to an optical structure similar to a convex lens, and the Fresnel lens structure refers to an optical structure similar to a Fresnel lens; both the convex lens and the Fresnel lens can converge light, thereby further adjusting the light beam transmitted from the first light control structure 1 to obtain a better optical effect.

[0067] Preferably, the second light-controlling structure 2 is a convex lens structure, and the curvature of the side of the second light-controlling structure 2 away from the inner cavity 5 is greater than the curvature of the side of the second light-controlling structure 2 close to the inner cavity 5 .

[0068] The side of the second light-control structure 2 close to the inner cavity 5 is the light-entering side. Setting it as a surface with a small curvature can reduce the obstruction of light and make the light more evenly distributed on the light-entering side surface of the second light-control structure 2; the side away from the inner cavity 5 is the light-emitting side. Setting it as a surface with a large curvature is beneficial to increasing the optical path and improving the light-emitting effect.

[0069] Further preferably, the second light-controlling structure 2 is a plano-convex lens structure with one convex side and one flat side, wherein the convex side is away from the inner cavity 5 and the flat side is close to the inner cavity 5 .

[0070] Preferably, the second light-controlling structure 2 is a Fresnel lens structure; and in the first embodiment: the side of the second light-controlling structure 2 close to the inner cavity 5 is a Fresnel surface, and the side of the second light-controlling structure 2 away from the inner cavity 5 is a plane.

[0071] The Fresnel lens described in this embodiment is a strip-shaped Fresnel lens, which extends along the first direction. The Fresnel surface is a surface provided with a plurality of 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 smoother, which helps to reduce damage to the Fresnel lens during installation and use.

[0072] In the second embodiment, the side of the second light-controlling structure 2 away from the inner cavity 5 is a Fresnel surface, and the side of the second light-controlling structure 2 close to the inner cavity 5 is a plane.

[0073] In the third embodiment, both sides of the second light-controlling structure 2 are Fresnel surfaces.

[0074] By setting both sides as Fresnel surfaces, the converging effect of the second light-controlling structure 2 on light can be increased under the condition of limited height of the raised strips.

[0075] Preferably, one side of the second light-control structure 2 is a Fresnel surface, and the other side is a sawtooth surface, wherein the sawtooth surface has a plurality of strip-shaped sawtooth protrusions; the sawtooth surface can meet specific lighting needs.

[0076] In some embodiments, the lens assembly is symmetrically arranged about a symmetry plane 7 , which passes through the central axis of the first light-controlling structure 1 and the second light-controlling structure 2 ; the symmetrical arrangement can improve the uniformity of the left and right light and simplify the manufacturing process.

[0077] Example 2 This embodiment provides an optical system, including a light source 6 and an integrally formed extruded lens assembly as described in Example 1. The light source 6 is located on a side of the first light-control structure 1 away from the inner cavity 5 .

[0078] Preferably, the light source 6 faces the first light-control structure 1 ; further preferably, the light source 6 faces the light-transmitting portion 13 .

[0079] Preferably, the light source 6 is an LED lamp bead, and a plurality of LED lamp beads are arranged along the first direction.

[0080] Example 3 This embodiment provides a lamp, including the integrally formed extruded lens assembly described in Example 1.

[0081] Example 4 This embodiment provides a lamp, including the optical system described in Example 2.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
