Description

Integrated lens and headlights Technical Field

[0001] The present application relates to the technical field of automobile lamps, and in particular to an integrated lens and a lamp. Background Art

[0002] In the related art, a car's high beam can provide the driver with long-range illumination in front of the vehicle, which greatly helps the driver's vision at night. In order to improve the driver's vision and expand the driver's observation field, the high beam light needs to be expanded in the horizontal and vertical directions.

[0003] High beams typically have reflector, projection, or lens structures. The high beam spot is typically created by machining the lens in a lens-type high beam. However, lens structures designed based on high beam lighting standards are often complex. This makes it difficult to precisely machine the lens, making it difficult to precisely control the shape of the high beam's output spot, thus preventing the desired high beam spot from being achieved.

[0029] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0030] Please refer to Figure 1, which shows a schematic diagram of the structure of an integrated lens 1 provided in one embodiment of the present application. The integrated lens 1 provided in an embodiment of the present application will be described in detail below in conjunction with Figure 1. As shown in Figure 1, the integrated lens 1 of the present application includes a light converging module 10 and a light beam expanding module 20.

[0031] In this embodiment, the integrated lens 1 can be used in a vehicle lamp. The light converging module 10 in the integrated lens 1 is used to converge the light beam emitted by the light source 2 and emit the converged light beam along the X-direction, which is the light emission direction of the vehicle lamp. The light converging module 10 is trumpet-shaped and includes at least one of a total internal reflection lens and a polished arc reflector, which is not limited here.

[0032] Optionally, the light converging module 10 includes a light incident surface and a light emitting surface. The light source 2 is disposed at the focal point of the light converging module 10, and the light source 2 is located on the light incident surface of the light converging module 10. The light beam emitted by the light source 2 is incident on the light incident surface of the light converging module 10, is reflected and converged by the reflective surface of the light converging module 10, and then is emitted from the light emitting surface of the light converging module 10. The configuration of the light converging module 10 can fully and effectively reflect the light beam emitted by the light source 2, thereby improving the utilization rate of the light beam output by the light source 2.

[0033] In this embodiment, a light expansion module 20 is provided at the light output of the light convergence module 10, and the light expansion module 20 includes a first cylindrical lens array and a second cylindrical lens array. The first cylindrical lens array is used to increase the divergence angle of the light beam in the Y direction, and the second cylindrical lens array is used to increase the divergence angle of the light beam in the Z direction. The Y direction is the direction perpendicular to the horizontal plane where the road surface is located, and the Z direction is the width direction of the road surface.

[0034] In some embodiments, the light expansion module 20 is disposed on the light exit surface of the light converging module 10. The light exit surface of the light converging module 10 is convex or concave toward the light incident surface, so as to form a first cylindrical lens array and a second cylindrical lens array in the light expansion module 20 on the light exit surface of the light converging module 10. In this case, the light exit surface of the light converging module 10 is a free-form surface. After the light beam emitted by the light source 2 is incident on the light incident surface of the light converging module 10, it is reflected and converged by the reflective surface of the inner wall of the light converging module 10 and is emitted from the light exit surface of the light converging module 10. The light exit surface, which is a cylindrical optical free-form surface, can diverge the converged light beam in the Y and Z directions, thereby increasing the divergence angle of the final emitted light beam in the Y and Z directions. Based on this, the final light beam emitted by the light expansion module 20 can form an exit light spot that is diffused in both the Y direction (i.e., the direction perpendicular to the horizontal plane of the road surface) and the Z direction (i.e., the width direction of the road surface).

[0035] Optionally, the design of the optical beam expansion module 20 is to process the light-emitting surface of the optical lens into a cylindrical optical free-form surface, so that the light-emitting surface of the optical lens has an array-distributed cylindrical microstructure, thereby enabling the optical beam expansion module 20 to diverge the incident light beam. Since the lens material is processed based on the needs of automobile high-beam lighting, compared with processing the light-emitting surface of the lens material into an irregular shape, the light-emitting surface of the lens material is processed into a cylindrical optical free-form surface, that is, the process of processing the optical beam expansion module 20 having a first cylindrical lens array and a second cylindrical lens array is easier to control, and the processing accuracy of the integrated lens 1 is higher, thereby ensuring that the divergence angle of the light beam emitted by the integrated lens 1 can be precisely controlled.

[0036] Optionally, the light output from the middle of a car's high beam is more concentrated and brighter, illuminating objects that are far away and high. The high beam can also improve vision and expand the field of view. When the integrated lens 1 of this embodiment is used in a car's high beam, the light converging module 10 in the integrated lens 1 converges the light beam emitted by the light source 2 and then emits it. The light beam expansion module 20 located at the light output of the light converging module 10 can diverge the light beam. The precisely machined light beam expansion module 20 can precisely control the divergence angle of the light beam, ensuring that the light beam ultimately emitted by the integrated lens 1 meets high-beam lighting standards.

[0037] The integrated lens 1 of the embodiment of the present application includes: a light converging module 10 for converging the light beam emitted by the light source 2 and emitting the converged light beam along the X direction, where the X direction is the light output direction of the vehicle headlight; and a light expanding module 20, which is arranged at the light output of the light converging module 10. The light expanding module 20 includes a first cylindrical lens array and a second cylindrical lens array. The first cylindrical lens array is used to increase the divergence angle of the light beam in the Y direction, and the second cylindrical lens array is used to increase the divergence angle of the light beam in the Z direction, where the Y direction is perpendicular to the horizontal plane of the road surface and the Z direction is the width direction of the road surface. Based on this, the light converging module 10 converges the light beam, thereby improving the utilization rate of the light beam emitted by the light source 2. The light expanding module 20, including the first cylindrical lens array and the second cylindrical lens array, increases the divergence angle of the converged light beam, thereby accurately controlling the divergence angle of the light beam in the Y direction and the Z direction, respectively, to obtain an ideal high-beam spot. At the same time, compared with processing the light-emitting surface of the lens into an irregular shape, the structure of the first cylindrical lens array and the second cylindrical lens array is simple. Therefore, in this application, the integrated lens 1 is processed to form a light expansion module 20 having a first cylindrical lens array and a second cylindrical lens array. The process is easier to control, and the processing accuracy of the integrated lens 1 is higher, so that the integrated lens 1 can accurately control the shape of the high-beam spot.

[0038] In some embodiments, please refer to FIG2 , which shows a schematic structural diagram of a beam expansion module 20 provided in an embodiment of the present application. As shown in FIG2 , the beam expansion module 20 of this embodiment includes a first cylindrical lens array 21 and a second cylindrical lens array 22 .

[0039] Optionally, the first cylindrical lens array 21 includes a plurality of first cylindrical lenses 211, and the extension direction of each first cylindrical lens 211 is parallel to the Z direction; the second cylindrical lens array 22 includes a plurality of second cylindrical lenses 221, and the extension direction of each second cylindrical lens 221 is parallel to the Y direction, that is, the plurality of first cylindrical lenses 211 and the plurality of second cylindrical lenses 221 are arranged perpendicular to each other.

[0040] In this embodiment, each first cylindrical lens 211 is tilted relative to the Y direction, and the upward refraction angle of each first cylindrical lens 211 for the light beam in the Y direction is greater than the downward refraction angle for the light beam.

[0041] As shown in FIG3 , FIG3 shows a schematic structural diagram of the first cylindrical lens 211 provided in an embodiment of the present application. The first cylindrical lens 211 forms a slight tilt angle θ relative to the Y direction (i.e., the direction perpendicular to the horizontal plane where the road surface is located), so that when the first cylindrical lens 211 diverges the incident light beam, the light beam emitted by the first cylindrical lens 211 is deflected upward in the Y direction, thereby making the upward refraction angle of the light beam by the first cylindrical lens 211 in the Y direction greater than the downward refraction angle of the light beam. In some embodiments, the tilt angle θ of the first cylindrical lens 211 relative to the Y direction can be 1.67°, which is not limited here.

[0042] In this embodiment, each second cylindrical lens 221 is disposed parallel to the Z direction, and the refraction angle of each second cylindrical lens 221 to the light beam to the left in the Z direction is equal to the refraction angle to the light beam to the right in the Z direction.

[0043] In some embodiments, the divergence angle of the light beam refracted by the first cylindrical lens array 21 in the Y direction may be in the range of [0°, 3°]; the divergence angle of the light beam refracted by the second cylindrical lens array 22 in the Z direction may be in the range of [-16°, 16°], without limitation herein. Furthermore, the refraction angles of the light beam in the Y direction of the multiple first cylindrical lenses 211 in the first cylindrical lens array 21 may be the same, or the refraction angles of the light beam from the center to the sides of the multiple first cylindrical lenses 211 may gradually increase or decrease; the refraction angles of the light beam in the Z direction of the multiple second cylindrical lenses 221 in the second cylindrical lens array 22 may be the same, or the refraction angles of the light beam from the center to the sides of the multiple second cylindrical lenses 221 may gradually increase or decrease.

[0044] Optionally, in response to the lighting requirements of car lights in different application scenarios, by adjusting the refraction angle of the light beam in the Y direction of the multiple first cylindrical lenses 211 in the light expansion module 20, and the refraction angle of the light beam in the Z direction of the multiple second cylindrical lenses 221, the light spot formed by the light beam emitted by the light convergence module 10 can meet the corresponding car light lighting requirements.

[0045] As shown in Figure 4, Figure 4 shows a schematic diagram of the output light spot 30 of the optical beam expansion module provided in an embodiment of the present application. The light beam emitted by the optical beam expansion module has a greater upward expansion in the Y direction (i.e., the direction perpendicular to the horizontal plane where the road surface is located) than a downward expansion, so that the output light spot 30 formed by the light beam in the Y direction is asymmetric along the optical axis of the light beam, and the output light spot 30 has a smaller expansion to both sides in the Y direction. The light beam emitted by the optical beam expansion module has an equal expansion to the left in the Z direction (i.e., the width direction of the road surface) as to the right, so that the output light spot 30 formed by the light beam in the Z direction is symmetric along the optical axis of the light beam, and the output light spot 30 has a larger expansion to both sides in the Z direction.

[0046] In this embodiment, after the divergence processing of the light expansion module 20, the light beam emitted by the integrated lens can form a lighting spot that meets the high beam lighting standard and diverges in the width direction of the road surface and in the direction perpendicular to the horizontal plane where the road surface is located. Moreover, since the upward divergence angle of the light beam is greater than the downward divergence angle, the lighting spot formed by the light beam can better illuminate the road signs set on the road to meet the high beam lighting requirements.

[0047] Please refer to FIG5 , which shows a schematic structural diagram of an integrated lens 1 according to another embodiment of the present invention. As shown in FIG5 , the integrated lens 1 according to the present invention includes a light converging module 10 and a light beam expanding module 20 .

[0048] In this embodiment, the light converging module 10 is used to converge the light beam emitted by the light source 2, and the light converging module 10 includes a first optical surface 11 and a second optical surface 12. The first optical surface 11 is disposed in the central region of the light emitting surface of the light converging module 10, and the second optical surface 12 is disposed around the periphery of the first optical surface 11. The light beam expansion module 20 is disposed in the light beam output direction of the first optical surface 11. The first optical surface 11 of the light converging module 10 is configured to emit a portion of the converged light beam along the X-direction to the light beam expansion module 20; the second optical surface 12 of the light converging module 10 is configured to emit the remaining light beams of the converged light beam, excluding the portion, along the X-direction.

[0049] Optionally, the integrated lens 1 of the present application further includes a collimating lens 40, which is disposed at the light exit of the first optical surface 11, and the light beam expansion module 20 is disposed on the light exit surface of the collimating lens 40. Specifically, on the light exit surface of the light converging module 10, the first optical surface 11 of the light converging module 10 is recessed from the light exit surface of the light converging module 10 toward the light incident surface thereof, and the collimating lens 40 can be built into the light converging module 10, with the light exit surface of the collimating lens 40 and the second optical surface 12 being in the same plane, thereby causing the light beam expansion module 20 disposed at the light exit surface of the collimating lens 40 to be in the same plane as the second optical surface 12.

[0050] Because the light converging module 10 is a total internal reflection lens, it may undergo uneven cooling during the molding process, resulting in strain and irregular shape within the lens material, which in turn makes the produced light converging module 10 fragile and uneven. By hollowing out the center of the light converging module 10 to accommodate a collimating lens 40 equipped with a beam expansion module 20, the problem of the excessive thickness of the center portion of the light converging module 10, which makes machining very difficult or even impossible, is solved. At the same time, the light beams emitted from different areas of the light output surface of the light converging module 10 can be shaped to obtain the desired illumination spot.

[0051] In this embodiment, the light-emitting surface of the collimating lens 40 is processed to form the light beam expansion module 20. The light-emitting surface of the light beam expansion module 20 (i.e., the light-emitting surface of the collimating lens 40) is convex or concave toward the light-incident surface, so as to form a first cylindrical lens array and a second cylindrical lens array on the light-emitting surface of the light beam expansion module 20. Since the structures of the first cylindrical lens array and the second cylindrical lens array are simpler than processing the light-emitting surface of the lens material into an irregular shape when processing the lens material, the process of processing the light-emitting surface of the lens material into a cylindrical optical free-form surface is easier to control, thereby ensuring the processing accuracy of the integrated lens 1 and ensuring that the divergence angle of the light beam emitted by the integrated lens 1 can meet the lighting requirements.

[0052] In this embodiment, as shown in Figures 6 and 7, Figure 6 shows a schematic diagram of the optical path of the outgoing light beam of the integrated lens provided in Figure 5 of the present application in the Y direction, and Figure 7 shows a schematic diagram of the optical path of the outgoing light beam of the integrated lens provided in Figure 5 of the present application in the Z direction.

[0053] Optionally, after the first optical surface 11 of the light converging module 10 in the integrated lens emits a portion of the light beam, the collimating lens 40 is used to collimate the portion of the light beam emitted from the first optical surface 11, and emit the collimated portion of the light beam to the light expansion module 20. The light expansion module 20 is used to diverge the portion of the light beam after the collimation process to increase the divergence angle of the portion of the light beam in the Y direction and the Z direction. The downward expansion of the portion of the light beam emitted by the light expansion module 20 in the Y direction is smaller than the upward expansion. The leftward expansion of the portion of the light beam emitted by the light expansion module 20 in the Z direction is equal to the rightward expansion, and the Y direction is a direction perpendicular to the horizontal plane where the road surface is located, and the Z direction is the width direction of the road surface.

[0054] Furthermore, the second optical surface 12 of the light converging module 10 in the integrated lens directly emits other light beams formed by the converging process without further processing the other light beams, so that the output light spots 30 formed by the other light beams are symmetrical in the Y direction and the Z direction along the optical axis of the light beam.

[0055] In the integrated lens 1 provided in this embodiment, part of the light beam emitted by the light expansion module 20 is processed by the collimating lens 40 and the light expansion module 20, and after being superimposed with the other light beams emitted by the light expansion module 20, the light beam finally emitted by the integrated lens 1 can form an exit light spot with strong illumination in the middle area and expansion to both sides in the Y direction and the Z direction, thereby improving the illumination range of the light beam while ensuring the illumination intensity of the middle area. In addition, the expansion of the exit light spot to both sides in the Y direction is smaller than the expansion to both sides in the Z direction, and the exit light spot formed by the light beam is asymmetric along the optical axis of the light beam in the Y direction and symmetric along the optical axis of the light beam in the Z direction, so that the light spot formed by the light beam emitted by the integrated lens 1 can meet the high-beam lighting requirements of the vehicle.

[0056] Please refer to Figure 8, which shows a schematic structural diagram of a vehicle lamp provided by an embodiment of the present application. As shown in Figure 8, the vehicle lamp 3 of the embodiment of the present application includes a light source 2 and the integrated lens 1 described in the above embodiment.

[0057] Optionally, light source 2 is disposed at the focal point of integrated lens 1. After the light beam emitted by light source 2 is incident on the light-entering surface of integrated lens 1, integrated lens 1 is used to converge and shape the light beam emitted by light source 2. The output light beam can form a light spot with strong illumination in the center area and extending perpendicular to the horizontal plane of the road surface and to both sides in the width direction of the road surface. This allows the light beam emitted by light source 2 to form an ideal high-beam illumination spot on the ground after passing through integrated lens 1. Light source 2 can be a light-emitting diode or a laser, which is not limited here.

[0058] In this embodiment, in the process of the light beam emitted by the light source 2 passing through the integrated lens 1 and then being emitted, the integrated lens 1 can fully and effectively converge the light beam emitted by the light source 2 and adjust the shape of the light beam before emitting it, thereby improving the utilization rate of the light beam output by the light source 2 by the car lamp 3, improving the energy-saving effect of the car lamp 3, and at the same time reducing the use of the light-emitting chip in the light source 2, reducing the volume of the car lamp 3, and reducing the manufacturing cost of the car lamp 3.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
