Description

Technical Field

[0001] This utility model patent relates to the technical field of irregularly shaped light spot lenses, specifically to irregularly shaped light spot lenses and irregularly shaped light spot lens modules. Background Technology

[0002] TIR lenses are made using the principle of total internal reflection to collect and reflect light. They can collect and reflect all the light emitted by LED beads. Under the same power, the light source utilization rate is greatly improved, and they have the characteristics of focusing light, low light loss, and good uniformity.

[0003] Currently, to improve the applicability of lenses, lenses are designed to project anisotropic light spots to meet various application requirements. For example, the prior patent with authorization announcement number CN114440142B discloses an LED optical system based on a microlens array to form anisotropic contour light spot, which relates to the field of optical imaging. The system includes an LED light source, a total internal reflection collimating lens for calibrating the light emitted by the LED light source into parallel light, a first lens array perpendicular to the parallel light, and a second lens array perpendicular to the parallel light. The first lens array includes multiple microlenses arranged in an array, each microlens including an inner plano-convex lens and an outer plano-convex lens, with the curvature of the inner plano-convex lens being greater than that of the outer plano-convex lens. The second lens array is identical to the first lens array. The second lens array is mirror-symmetrically arranged with the first lens array and located at the focal plane of the inner plano-convex lens of the first lens array.

[0004] In the existing technology, the lens forms a hollow light spot. The shape of the hollow light spot lacks characteristics. At the same time, the integrity of the light spot is insufficient, which easily leads to poor viewing of the light spot and insufficient visual aesthetics. Utility Model Content

[0005] The purpose of this invention is to provide an irregularly shaped light spot lens and an irregularly shaped light spot lens module, which aims to solve the problem of insufficient visual aesthetics of the light spots projected by the lens in the prior art.

[0006] This invention is implemented as follows: an irregularly shaped light spot lens includes a light-inlet section, a light-outlet section, and a total reflection surface. The light-inlet section includes an inner light-inlet surface and a light-inlet side surface, which are respectively used to receive light emitted by a light source, and the light-inlet side surface is used to refract light to the total reflection surface. The light-outlet section includes an inner light-outlet surface and an outer light-outlet surface. The inner light-outlet surface is arranged correspondingly to the inner light-inlet surface, and the inner light-outlet surface is used to receive light passing through the inner light-inlet surface. The outer light-outlet surface includes multiple light-outlet curved surfaces, and the total reflection surface is used to reflect light to each of the light-outlet curved surfaces. The inner light-outlet surface and each of the light-outlet curved surfaces are respectively used to refract light outward to form an irregularly shaped light spot.

[0007] Furthermore, a light outlet is formed in the middle of the light-emitting surface, and each of the light-emitting curved surfaces is arranged in a ring around the light outlet in a curved shape. Along the direction away from the light source, the inner light-entry surface, the inner light-emitting surface, and the light outlet are arranged in a corresponding order. The inner light-emitting surface refracts light outward through the light outlet to form a light spot.

[0008] Furthermore, the irregularly shaped light spot lens includes a light-cutting surface, which is arranged in an enclosing manner to form a light-cutting cavity. The light-cutting surface is located between the inner light-emitting surface and the light-emitting port, and the light refracted by the inner light-emitting surface passes through the light-cutting cavity to the light-emitting port. The light-cutting surface is used to prevent light from being exposed.

[0009] Furthermore, the cross-sectional area of ​​the light outlet is larger than the cross-sectional area of ​​the inner light-emitting surface, and the cross-sectional area of ​​the inner light-emitting surface is larger than the cross-sectional area of ​​the inner light-entering surface.

[0010] Furthermore, the light-emitting curved surfaces are arranged sequentially around each other to form two large wing light areas and two small wing light areas. The inner light-emitting surface refracts light to form the main light spot, the large wing light areas refract light to form large wing light spots, and the small wing light areas refract light to form small wing light spots. The two large wing light spots are spliced ​​together with the two sides of the main light spot in the lateral direction, and the two small wing light spots are spliced ​​together with the two sides of the main light spot in the lateral direction.

[0011] Furthermore, each of the light-emitting curved surfaces is arranged in sequence to form a head light area and a tail light area. The head light area refracts light to form a head light spot, and the tail light area refracts light to form a tail light spot. The head light spot and the tail light spot are spliced ​​together with the longitudinal sides of the main light spot.

[0012] Furthermore, the various light-emitting curved surfaces are arranged sequentially to form multiple large petal light areas and multiple small petal light areas. The large petal curved surfaces refract light to form large petal light spots, the small petal curved surfaces refract light to form small petal light spots, and the inner light-emitting surface refracts light to form the main light spot. The small petal light spots and the large petal light spots are respectively arranged in a corresponding manner around the main light spot at intervals, and the small petal light spots and the large petal light spots are arranged in an alternating manner. The small petal light spots and the main light spot are arranged in a corresponding manner, either spliced ​​or spaced, and the large petal light spots and the main light spot are arranged in a corresponding manner, either spliced ​​or spaced.

[0013] Furthermore, each of the light-emitting curved surfaces is arranged sequentially around to form a central petal area, two small petal light areas, and two large petal light areas. The light refracted by the central petal area forms a central petal light spot, the light refracted by the small petal curved surfaces forms small petal light spots, the light refracted by the large petal curved surfaces forms large petal light spots, and the light refracted by the inner light-emitting surface forms a main light spot. One end of the central petal light spot is spliced ​​with the main light spot, and the other end of the central petal light spot extends in a direction away from the main light spot. The central petal light spot is located between the two small petal light spots, and the small petal light spots are spliced ​​or spaced correspondingly to the main light spot. The two small petal light spots are located between the two large petal light spots, and the large petal light spots are spliced ​​or spaced correspondingly to the main light spot.

[0014] Furthermore, each of the light-emitting curved surfaces is arranged in sequence to form multiple blade areas. The light refracted by the blade areas forms blade light spots, and the light refracted by the inner light-emitting surface forms a main light spot. Each of the blade light spots is arranged in a corresponding manner around the circumference of the main light spot, and the blade light spots and the main light spot are arranged in a spliced ​​manner.

[0015] An irregularly shaped light spot lens module includes a lens body and an integrated bracket. The lens body includes a light-inlet section, a light-outlet section, and a total reflection surface. The light-inlet section includes an inner light-inlet surface and a light-inlet side surface, which are used to receive light emitted by a light source. The light-inlet side surface is used to refract light to the total reflection surface. The light-outlet section includes an inner light-outlet surface and an outer light-outlet surface. The inner light-outlet surface is arranged correspondingly to the inner light-inlet surface, and the inner light-outlet surface is used to receive light passing through the inner light-inlet surface. The outer light-outlet surface includes multiple light-outlet curved surfaces, and the total reflection surface is used to reflect light to each of the light-outlet curved surfaces. The inner light-outlet surface and each of the light-outlet curved surfaces are used to refract light outward to form an irregularly shaped light spot.

[0016] The integrated bracket includes a cover and a plate, which are integrally formed. The cover is used to cover the lens body, and the plate is used to assemble the light source and the lens body.

[0017] Compared with existing technologies, the irregularly shaped light spot lens and irregularly shaped light spot lens module provided by this utility model, when in use, the light source emits light to the inner light-incoming surface and the light-incoming side surface. The inner light-incoming surface refracts the light to the inner light-exiting surface, while the light-incoming side surface refracts the light to the full-radiation surface, and then reflects the light to the light-exiting curved surface. The inner light-exiting surface and each light-exiting curved surface synchronously refract the light outward and converge to form an irregularly shaped light spot. In this way, the inner light-exiting surface and each light-exiting curved surface cooperate to form irregularly shaped light spots of different shapes, improving the visual appeal and aesthetics of the light spots, meeting the needs of different scenarios, and avoiding the use of multiple light sources or multiple lenses to achieve irregularly shaped light spots, greatly reducing production costs and assembly difficulty.

[0041] Reference Figure 1-20 The image shown is a preferred embodiment of the present invention.

[0042] An irregularly shaped light spot lens includes a light-inlet section 1, a light-outlet section 2, and a total reflection surface 3. The light-inlet section 1 includes an inner light-inlet surface 11 and a light-inlet side surface 12. The inner light-inlet surface 11 and the light-inlet side surface 12 are used to receive light emitted by a light source, and the light-inlet side surface 12 is used to refract light to the total reflection surface 3. The light-outlet section 2 includes an inner light-outlet surface 21 and an outer light-outlet surface 22. The inner light-outlet surface 21 is arranged correspondingly to the inner light-inlet surface 11, and the inner light-outlet surface 21 is used to receive light passing through the inner light-inlet surface 11. The outer light-outlet surface 22 includes multiple light-outlet curved surfaces 221. The total reflection surface 3 is used to reflect light to each light-outlet curved surface 221. The inner light-outlet surface 21 and each light-outlet curved surface 221 are used to refract light outward to form an irregularly shaped light spot.

[0043] In the aforementioned irregularly shaped light spot lens, when in use, the light source emits light to the inner light-entering surface 11 and the light-entering side surface 12. The inner light-entering surface 11 refracts the light to the inner light-exiting surface 21, while the light-entering side surface 12 refracts the light to the full-radiation surface, and then reflects the light to the light-exiting curved surface 221. The inner light-exiting surface 21 and each light-exiting curved surface 221 simultaneously refract the light outwards and converge to form an irregularly shaped light spot. In this way, different irregularly shaped light spots are formed by the cooperation of the inner light-exiting surface 21 and each light-exiting curved surface 221, which improves the visual appeal and aesthetics of the light spot, meets the needs of different scenarios, and avoids the use of multiple light sources or multiple lenses to achieve irregularly shaped light spots, greatly reducing production costs and assembly difficulty.

[0044] A light outlet 222 is formed in the middle of the light-emitting surface 22. Each light-emitting curved surface 221 is arranged in a ring around the light outlet 222 and is arranged in a curved shape. Along the direction away from the light source, the inner light-entry surface 11, the inner light-emitting surface 21 and the light outlet 222 are arranged in a corresponding order. The inner light-emitting surface 21 refracts light outward through the light outlet 222 to form a light spot.

[0045] In this way, the inner light-emitting surface 21 directly refracts light outward through the light-emitting port 222 to form a light spot, and through the cooperation of various curved surfaces, an irregular light spot is formed, which facilitates the formation of irregular light spots.

[0046] The irregularly shaped light spot lens includes a light-cutting surface, which is arranged in an enclosing manner to form a light-cutting cavity 4. The light-cutting surface is located between the inner light-emitting surface 21 and the light-emitting port 222, and the light refracted by the inner light-emitting surface 21 passes through the light-cutting cavity 4 to the light-emitting port 222. The light-cutting surface is used to prevent light from being exposed.

[0047] At the same time, the inner light-inlet surface 11 and the inner light-outlet surface 21 work together to focus the light, avoid yellow spots or shadows, and improve the imaging effect of the light spot.

[0048] Furthermore, the light-blocking surface reduces glare and improves the user experience of the lens.

[0049] The cross-sectional area of ​​the light outlet 222 is larger than that of the inner light outlet surface 21, and the cross-sectional area of ​​the inner light outlet surface 21 is larger than that of the inner light inlet surface 11. In this way, all the light rays passing through the inner light inlet surface 11 can be refracted to the inner light outlet surface 21, and all the light rays refracted by the inner light outlet surface 21 can be refracted outward to form light spots, ensuring the imaging effect of irregular light spots, and at the same time, effectively ensuring the integrity of irregular light spots.

[0050] Butterfly Example:

[0051] Each light-emitting surface 221 is arranged in sequence to form two large wing light areas and two small wing light areas. The inner light-emitting surface 21 refracts light to form the main light spot, the large wing light areas refract light to form large wing light spots, and the small wing light areas refract light to form small wing light spots. The two large wing light spots are spliced ​​together with the two sides of the main light spot in the lateral direction, and the two small wing light spots are spliced ​​together with the two sides of the main light spot in the lateral direction.

[0052] In this way, under the influence of the two large wing light areas and the two small wing light areas, two large wing light spots and two small wing light spots are formed. The two large wing light spots and the two small wing light spots are spliced ​​with the main light spot to form irregular light spots. The irregular light spots present the large wings and small wings of the butterfly, making the irregular light spots tend to resemble the shape of the butterfly, which is more ornamental and visually appealing.

[0053] The light-emitting surface 221 is arranged in a frosted manner to improve the light mixing effect of the lens; or, the light-emitting surface 221 is arranged in a scale-like manner to improve the light mixing effect of the lens.

[0054] The inner light-emitting surface 21 is arranged in a frosted state to improve the light mixing effect of the lens; or, the inner light-emitting surface 21 is arranged in a scaled state to improve the light mixing effect of the lens.

[0055] The large wing light area corresponds to one light-emitting surface 221, or the large wing light area corresponds to two or more light-emitting surfaces 221; this facilitates the formation of the large wing light spot.

[0056] The small wing light area corresponds to one light-emitting surface 221, or the small wing light area corresponds to two or more light-emitting surfaces 221; this facilitates the formation of the small wing light spot.

[0057] The cross-section of the large wing light area is larger than that of the small wing light area. As a result, the area of ​​the large wing light spot is larger than that of the small wing light spot, making the irregular light spot more like a butterfly shape.

[0058] Along the direction away from the light outlet 222, the light-emitting curved surface 221 is arranged in a gradually inclined direction, so as to realize the change of the angle and facilitate the formation of irregular light spots.

[0059] The inclination of the light-emitting surface 221 corresponding to the large wing light area is not the same as the inclination of the light-emitting surface 221 corresponding to the small wing light area, which facilitates the formation of butterfly-shaped irregular light spots.

[0060] The different light-emitting surfaces 221 contained in the large wing light area are arranged at different angles to facilitate the formation of butterfly-shaped irregular light spots.

[0061] Each light-emitting curved surface 221 is arranged in sequence to form a head light area and a tail light area. The head light area refracts light to form a head light spot, and the tail light area refracts light to form a tail light spot. The head light spot and the tail light spot are spliced ​​together with the longitudinal sides of the main light spot.

[0062] In this way, under the influence of the head light area and the tail light area, head light spots and tail light spots are formed, and the head light spots and tail light spots are spliced ​​with the main light spots to form irregular light spots, making the irregular light spots tend to resemble the shape of a butterfly, which makes them more ornamental and visually appealing.

[0063] Furthermore, the two large wing-shaped light spots represent the large wings of a butterfly, the two small wing-shaped light spots represent the small wings of a butterfly, the head light spot represents the head of a butterfly, and the tail light spot represents the tail of a butterfly. Combined with the main body of the light spots, the irregular light spots tend to resemble the shape of a butterfly, making them more ornamental and visually appealing.

[0064] like Figure 4 As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper light path is the light path of the large wing light area, which forms the large wing light spots on both sides. The lower light path is the light path of the small wing light area, which forms the small wing light spots on both sides.

[0065] like Figure 5As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper light path is the light path of the head light area, which forms the head light spot. The lower light path is the light path of the tail light area, which forms the tail light spot.

[0066] Lotus Example 1:

[0067] Each light-emitting surface 221 is arranged in sequence to form multiple large petal light areas and multiple small petal light areas. The large petal surfaces refract light to form large petal light spots, and the small petal surfaces refract light to form small petal light spots. The inner light-emitting surface 21 refracts light to form the main light spot. Each small petal light spot and each large petal light spot are arranged in a corresponding manner around the main light spot, and each small petal light spot and each large petal light spot are arranged in an alternating manner. The small petal light spots and the main light spot are arranged in a corresponding manner, either spliced ​​or spaced. The large petal light spots and the main light spot are also arranged in a corresponding manner, either spliced ​​or spaced.

[0068] In this way, the light areas of each large petal and each small petal are combined to make the irregular light spots tend to resemble the shape of a lotus flower, making them more ornamental and visually appealing.

[0069] The light-emitting surface 221 is arranged in a frosted manner to improve the light mixing effect of the lens; or, the light-emitting surface 221 is arranged in a scale-like manner to improve the light mixing effect of the lens.

[0070] The inner light-emitting surface 21 is arranged in a frosted state to improve the light mixing effect of the lens; or, the inner light-emitting surface 21 is arranged in a scaled state to improve the light mixing effect of the lens.

[0071] Each light-emitting curved surface 221 is arranged in a convex or concave manner, which facilitates the staggered arrangement of light spots of each small petal and light spots of each large petal. The resulting irregular light spots are more similar to the shape of a lotus flower, making them more ornamental and visually appealing.

[0072] like Figure 8 As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper light path is the light path of the small petal light area, which forms multiple small petal light spots. The lower light path is the light path of the large petal light area, which forms multiple large petal light spots.

[0073] Lotus Example 2:

[0074] Each light-emitting surface 221 is arranged in sequence to form a central petal area, two small petal light areas, and two large petal light areas. The light refracted by the central petal area forms a central petal light spot, the light refracted by the small petal surfaces forms a small petal light spot, the light refracted by the large petal surfaces forms a large petal light spot, and the light refracted by the inner light-emitting surface 21 forms a main light spot. One end of the central petal light spot is spliced ​​with the main light spot, and the other end of the central petal light spot extends in a direction away from the main light spot. The central petal light spot is located between the two small petal light spots. The small petal light spots are spliced ​​or spaced corresponding to the main light spot. The two small petal light spots are located between the two large petal light spots. The large petal light spots are spliced ​​or spaced corresponding to the main light spot.

[0075] In this way, the combined effect of the central petal area, the two small petal light areas, and the two large petal light areas makes the irregular light spots tend to resemble the shape of a lotus flower, making them more ornamental and visually appealing.

[0076] Each light-emitting curved surface 221 is arranged in sequence to form at least one bottom petal area. The bottom petal area refracts light to form bottom petal light spots. The bottom petal light spots are arranged around the outer edge of the large petal light spots. In this way, the irregular light spots are more similar to the shape of a lotus flower, and the number of petals of the lotus flower is richer, making it more ornamental and visually appealing.

[0077] The light outlet 222 is arranged in an irregular shape to facilitate the formation of a lotus-shaped light spot.

[0078] The irregularly shaped light spot lens includes a light-cutting surface, which is arranged in an enclosing manner to form a light-cutting cavity 4. The light-cutting surface is located between the inner light-emitting surface 21 and the light-emitting port 222. The light refracted by the inner light-emitting surface 21 passes through the light-cutting cavity 4 to the light-emitting port 222. The light-cutting cavity 4 is arranged in an inclined extension to facilitate the presentation of large petal light spots, small petal light spots and bottom petal light spots.

[0079] Each light-emitting surface 221 is arranged in a different plane, that is, each light-emitting surface 221 is staggered. This facilitates the presentation of light spots of large petals, small petals and bottom petals, and makes the light spots formed tend to resemble the shape of a lotus flower, which is more ornamental and visually appealing.

[0080] like Figure 13 As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper light path is the light path of the central petal light area, which forms the central petal light spot. The lower light path is the light path of the bottom petal light area, which forms the bottom petal light spot.

[0081] like Figure 14As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper light path is the light path of the small petal light area, which forms the small petal light spots on both sides. The lower light path is the light path of the large petal light area, which forms the large petal light spots on both sides.

[0082] Blade Example:

[0083] Each light-emitting curved surface 221 is arranged in sequence to form multiple blade areas. The light refracted by the blade areas forms blade light spots, and the light refracted by the inner light-emitting surface 21 forms the main light spot. Each blade light spot is arranged in a corresponding manner around the circumference of the main light spot, and the blade light spots and the main light spot are spliced ​​together.

[0084] In this way, by coordinating the various leaf areas with the main light spot, the irregular light spot becomes more like a four-leaf clover shape, making it more ornamental and visually appealing.

[0085] Depending on the requirements, the number of leaf areas can be selected to customize the number of leaves for irregular light spots, achieving shapes such as clover and five-leaf clover.

[0086] The inner light-emitting surface 21 is arranged in a smooth shape to improve the light-gathering effect.

[0087] like Figure 18 As shown, the middle light path is the light path projected by the inner light-emitting surface, which forms the main light spot. The upper and lower light paths are the light paths of each blade area, forming multiple blade light spots through the blade areas.

[0088] Lens module example:

[0089] The irregularly shaped light spot lens module includes a lens body and an integrated bracket 5. The lens body includes a light-inlet section 1, a light-outlet section 2, and a total reflection surface 3. The light-inlet section 1 includes an inner light-inlet surface 11 and a light-inlet side surface 12. The inner light-inlet surface 11 and the light-inlet side surface 12 are used to receive light emitted by the light source, and the light-inlet side surface 12 is used to refract light to the total reflection surface 3. The light-outlet section 2 includes an inner light-outlet surface 21 and an outer light-outlet surface 22. The inner light-outlet surface 21 is arranged correspondingly to the inner light-inlet surface 11, and the inner light-outlet surface 21 is used to receive light passing through the inner light-inlet surface 11. The outer light-outlet surface 22 includes multiple light-outlet curved surfaces 221. The total reflection surface 3 is used to reflect light to each light-outlet curved surface 221. The inner light-outlet surface 21 and each light-outlet curved surface 221 are used to refract light outward to form an irregularly shaped light spot. The integrated bracket 5 includes a cover and a plate. The cover and the plate are integrally formed. The cover is used to cover the lens body, and the plate is used to assemble the light source and the lens body.

[0090] The aforementioned irregularly shaped light spot lens module, under the action of the integrated bracket 5, facilitates the assembly of the lens body and the light source, while enhancing the cooperation between the light source and the lens body, ensuring the presentation of the irregularly shaped light spot.
