Detailed Description

For the purposes of making the objects, technical solutions and advantages of one or more embodiments of the present specification more clear, the technical solutions of one or more embodiments of the present specification will be clearly and completely described below in connection with specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without undue burden, are intended to be within the scope of one or more embodiments herein.

The structures, proportions, sizes, etc. shown in the drawings attached hereto are for illustration purposes only and are not intended to limit the scope of the utility model, which is defined by the claims, but rather by the claims.

It should be noted that in the description herein, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Unless otherwise indicated, the meaning of "a plurality" is two or more. The terms "center," "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used for convenience in describing embodiments of the utility model and simplifying the description based on the orientation or positional relationship shown in the drawings, and do not denote or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model.

In the following description, the up, down, left, right, front, and rear directions are all based on the vehicle driving position.

In addition, in the following description, gathering or converging the light may mean that the light is deflected to a certain extent toward a preset center position, so that the cross-sectional area of the light beam formed by the light is reduced to a certain extent, and it is not necessary to intersect the gathered or converged light at a point.

In the embodiments of the present specification, taking fig. 1, 4, 6 and 9 as examples, there is provided a lamp optical element including an light-entering portion 1, a light-passing portion 2 and a light-exiting portion 3 integrally formed, and light incident from the light-entering portion 1 is converged by the light-passing portion 2 and then emitted from the light-exiting portion 3 to form a light shape. The light entering portion 1 is close to the light source, and collects light emitted by the light source and performs secondary light distribution, so that the light is converged at a focal plane of the light emitting surface 31 of the light emitting portion and then emitted from the light emitting surface 31 of the light emitting portion 3 to form a light shape.

Specifically, the light-in portion 1 is configured such that light rays are deflected in the light-passing portion 2 toward the optical axis position of the light-out surface 31 of the light-out portion 3 and an intermediate light image is formed at the focal plane of the light-out surface 31, and the light-out portion 3 is configured to image the intermediate light image in front of the lamp optical element. In practical use, the lamp optical element may form a target light shape or a portion of a target light shape in a traffic space in front of a vehicle in which a lamp module including the lamp optical element is installed.

For example, a lamp optical element as shown in at least one of fig. 1, 4,6, and 9 or a lamp optical element obtained by permutation and combination based on at least part of the features shown in fig. 1, 4,6, and 9 may be formed in a traffic space in front of a vehicle in which a lamp module including the corresponding lamp optical element is installed. Alternatively, the lamp optical element of the embodiments of the present specification may also be configured as a front fog lamp, a corner lamp, or a steering assist lamp.

As an example, fig. 18 shows a schematic view of a low beam shape formed by a lamp optical element according to at least some embodiments of the present specification. The low beam shape shown in fig. 18 may be formed by a lamp module including a lamp optical element as shown in fig. 6 or 9. In the low beam shape shown in fig. 18, there is a stepped cut-off line.

Based on the embodiment of the present disclosure, the light incident portion 1 in the light optical element makes the light beams emitted from each light receiving structure 11 gather towards the optical axis position of the light emitting surface 31 of the light emitting portion 3, so that the light illumination function can be realized by using a shorter length of the light optical element and a smaller size of the light emitting surface 31, the structure is simple and efficient, the manufacturing cost is reduced, the manufacturing and assembling precision of the light module is improved, and the smaller opening of the light emitting surface brings higher freedom of modeling design of the whole light, and the design difficulty of the whole light structure is reduced while the appearance is attractive.

Based on the embodiment of the specification, by providing the car light optical element formed by integrating the light inlet part 1, the light passing part 2 and the light outlet part 3, the car light optical component at least comprising a light receiving structure, an outer lens and other parts in the prior art is replaced, so that the material cost is lower, the assembly links can be reduced, the assembly difficulty can be reduced, and the production speed can be increased; and fewer parts have fewer part tolerances and assembly tolerances, so that the quality and performance stability of the product can be improved.

Compared with the traditional scheme, the car light optical element provided based on the embodiment of the specification reduces the quantity of the refraction surfaces through which light passes, and the light is transmitted in the medium, so that the light utilization efficiency is higher, and the light channel and the light emitting surface can be smaller. The height of the common car light optical component in the market at present is usually more than 25mm, and the height of the light emergent surface of the car light optical element provided by the embodiment of the specification can be within 10mm (even can be within 8 mm), the width can be within 30mm (even can be within 25 mm), and the size of the common car light optical component is far smaller than that of the common car light optical component in the market. The smaller light emergent surface enables the space occupied by the optical element of the car lamp to be smaller and more attractive, the structural design difficulty of the whole lamp can be reduced, and higher freedom degree of modeling design of the whole lamp is brought.

In at least some embodiments of the present disclosure, the light-entering portion 1 may include a plurality of light-receiving structures 11.

Specifically, the light receiving structures 11 are close to the light source, collect light emitted by the light source, and perform secondary light distribution. For example, the distance between the light source and the light receiving structure may be set to be not more than 5mm to improve the light utilization.

In practical applications, the light sources and the light receiving structures 11 may be in one-to-one correspondence, that is, one light receiving structure 11 may correspond to one light source. The number of light receiving structures 11 and the number of light sources may be set as desired, for example, according to the luminous flux of the light sources and the performance requirements of the target light shape.

Alternatively, the plurality of light receiving structures 11 may be linearly arranged in one direction or may be arranged in a matrix form. Preferably, as shown in fig. 1, 2, 4, 6, 7, 9, 10 and 12, the plurality of light receiving structures 11 may be linearly arranged in the left-right direction so as to form a light emitting shape satisfying a wide range. The arrangement of the plurality of light receiving structures 11 may not be limited to the examples as given in fig. 1, 2, 4, 6, 7, 9, 10 and 12.

In at least some embodiments of the present disclosure, the plurality of light receiving structures 11 may deflect light rays toward the optical axis position of the light emitting surface 31 in the light passing portion 2.

Specifically, as shown in fig. 2, the light emitting directions of the respective light receiving structures 11 may converge toward the optical axis (not shown) of the light emitting surface 31, that is, at least part of the light emitting directions of the light receiving structures 11 may not be parallel to the optical axis direction of the light emitting surface 31. As a result, as shown in fig. 1, 2, 4, 6, 7, 9, 10, and 12, the light transmitting portion 2 of the lamp optical element may be configured such that the width of the longitudinal section of the light transmitting portion 2 on the side closer to the light emitting portion 3 is smaller than the width of the longitudinal section of the Yu Tongguang portion 2 on the side closer to the light entering portion 1. Thus, a light-emitting surface of a smaller size can be formed in practical use.

Specifically, as shown in fig. 2, the light-emitting directions of the respective light-receiving structures 11 may be deflected to different degrees toward the optical axis position (not shown) of the light-emitting surface 31. By adjusting the deflection degree of each light receiving structure 11 independently, an intermediate light image of a predetermined shape can be formed in the focal plane of the light emitting surface 31, and then projected in front of the lamp optical element into a predetermined light shape satisfying regulations and design requirements.

For example, alternatively, the light receiving structure 11 of the plurality of light receiving structures 11, which is far from the optical axis of the light exit surface 31, may deflect light more than the light receiving structure 11 of the plurality of light receiving structures 11, which is close to the optical axis of the light exit surface 31.

In practical application, the form of light entering the light transmitting portion 2 may include a form of direct light condenser as shown in the drawings, and the form of the light receiving structure 11 as a condenser in the present application is not limited to the examples given in the drawings. For example, the light receiving structure 11 may be provided in the form of a fresnel lens direct light, not limited thereto.

In at least some embodiments of the present description, as shown in fig. 1 to 8, the lamp optical element may be flat as a whole, in which case light rays enter the light-passing portion 2 from the rear side directly through the light-entering portion 1.

In addition, in at least some embodiments of the present specification, as shown in fig. 9 to 15, the lamp optical element may be bent as a whole, in which case light is incident from the lower side (or may be the upper side) into the light-passing portion 2 through the light-entering portion 1. In practical application, the light-reflecting structure 12 can be added in the light-entering part 1 to cooperate to realize that light rays are emitted into the light-transmitting part 2.

As an example, as shown in fig. 9 and 11, the light receiving structure 11 of the light incident portion 1 may be configured to be located at the lower side of the lamp optical element body, whereby light is incident into the light receiving structure 11 from the lower side, projected onto the light reflecting structure 12 via the light receiving structure 11, and reflected into the light passing portion 2 via the light reflecting structure 12. As another example, the light receiving structure 11 of the light incident portion 1 may be configured to be located at an upper side of the lamp optical element body, whereby light is incident into the light receiving structure 11 from the upper side, is projected onto the light reflecting structure 12 through the light receiving structure 11, and is reflected into the light passing portion 2 through the light reflecting structure 12.

In at least some embodiments of the present specification, as shown in fig. 9 and 11, the light incident portion 1 may include a plurality of light receiving structures 11 and a light reflecting structure 12 located downstream of the plurality of light receiving structures 11 along an optical path, and the light reflecting structure 12 may be configured to reflect light rays exiting from the plurality of light receiving structures 11 to deflect toward an optical axis position of the light exit surface 31 in the light passing portion 2.

In practical use, at least one of the light receiving structure 11 and the light reflecting structure 12 may be configured such that light rays incident thereon are deflected toward the optical axis position of the light exit surface 31. For example, the plurality of light receiving structures 11 may be configured such that the light rays exiting from the plurality of light receiving structures 11 are deflected toward the optical axis position of the light exit surface 31, and the light reflecting structure 12 may be configured to reflect the light rays exiting from the plurality of light receiving structures 11 to be deflected toward the optical axis position of the light exit surface 31 in the light passing portion 2. As another example, the plurality of light receiving structures 11 may be configured such that the light rays exiting from the plurality of light receiving structures 11 are deflected toward the optical axis position of the light exit surface 31, but the light reflecting structure 12 need not be configured to reflect the light rays exiting from the plurality of light receiving structures 11 to be deflected toward the optical axis position of the light exit surface 31 in the light passing portion 2. For another example, the plurality of light receiving structures 11 need not be configured such that the light rays exiting from the plurality of light receiving structures 11 are deflected toward the optical axis position of the light exit surface 31, but the light reflecting structure 12 may be configured such that the light rays exiting from the plurality of light receiving structures 11 are reflected so as to be deflected toward the optical axis position of the light exit surface 31 in the light passing portion 2.

Specifically, the light reflecting structure 12 may be a total reflection surface. That is, light is incident on the light reflecting structure 12 at an angle greater than the critical angle, and only light reflection occurs on the light reflecting structure 12, and no light refraction occurs. Optionally, a reflective coating may be applied to the outside of the retroreflective structure 12 to enhance the reflective properties of the retroreflective structure 12.

Alternatively, the retroreflective structure 12 may include a continuous reflective surface, which may be curved to project toward the rear. In practical use, the curved surface may be configured such that the light rays projected thereon are gathered to some extent in the left-right direction, that is, deflected toward the optical axis position of the light-emitting surface 31 in the left-right direction.

Alternatively, as shown in fig. 9, 10 and 12, the light reflecting structure 12 may include a plurality of sub light reflecting structures 121. The plurality of sub-reflecting structures 121 may be configured to reflect light at different angles to deflect the light at different degrees. Thus, by adjusting the deflection degree of the light by each sub-reflecting structure 121 independently, an intermediate light image of a predetermined shape can be formed in the focal plane of the light-emitting surface 31, and projected in front of the lamp optical element into a predetermined light shape satisfying the regulations and design requirements

For example, alternatively, the degree of deflection of the light by the sub-reflection structure 121 of the plurality of sub-reflection structures 121, which is far from the optical axis of the light exit surface 31, may be greater than the degree of deflection of the light by the sub-reflection structure 121 of the plurality of sub-reflection structures 121, which is close to the optical axis of the light exit surface 31.

Alternatively, any two adjacent sub-reflective structures 121 in the plurality of sub-reflective structures 121 may be directly spliced or spliced with a step surface.

Alternatively, the reflection angle of each sub-reflection structure 121 of the plurality of sub-reflection structures 121 may be set according to actual light shape requirements.

Alternatively, the size of each sub-reflecting structure 121 of the plurality of sub-reflecting structures 121 may be set according to actual light shape requirements. For example, one light receiving structure 11 may correspond to one or more sub-light reflecting structures 121.

As an example, as shown in fig. 9, the lamp optical element may include 7 light receiving structures 11 and a light reflecting structure 12 including a plurality of sub light reflecting structures 121. In this example, 1 of the 7 light receiving structures 11 is arranged to correspond to one larger-sized sub-reflecting structure 121, and 6 of the 7 light receiving structures 11 are arranged to each correspond to a plurality of smaller-sized sub-reflecting structures 121. Thus, the adjustment of the target light shape can be achieved by freely adjusting the reflection angle of each sub-reflection structure 121.

The lamp optical element provided by the implementation of the specification can provide a light shape without a cut-off line, and can be applied to a high beam in practical application. Optionally, a light cut-off structure may also be provided in the light-passing portion 2 for forming a light shape having a cut-off line. The following is a description with reference to fig. 4 to 12.

In at least some embodiments of the present description, the lower surface area of the light-passing portion 2 may have a recessed structure 21 having a recessed depth smaller than the thickness of the lamp optical element.

Specifically, the concave structure 21 may include a first side 211 near the light incident portion 1 and a second side 212 far from the light incident portion 1. Thereby, the concave structure 21 can form a light cut-off structure so that the light incident into the light passing portion 2 is cut off by the light cut-off structure and then emitted in a light shape having a cut-off line. Wherein the shape of the boundary 213 between the first side 211 and the second side 212 may be adapted to the shape of the light-shaped cutoff line.

At least one focal point of the light emitting surface 31 of the light emitting portion 3 may be located near the boundary line 213. For example, if the light-emitting surface 31 includes a focal point, the focal point may be near the boundary 213. For another example, if the light-emitting surface 31 includes a plurality of focuses, at least one of the plurality of focuses may be located near the boundary 213. Thus, a clear cut-off line structure can be formed in the light pattern.

In practical applications, the light reflected from the light reflecting structure 12 may include a first portion of light reflected to exit the light exit surface 31 and a second portion of light reflected to exit the non-light exit surface. The second portion of light may include light reflected to the upper surface of the light-transmitting portion 2 and then reflected to the lower surface.

Alternatively, the side edge of the first side surface 211 near the light receiving structure may be connected to the light receiving structure 11, so that the included angle between the first side surface 211 and the optical axis of the light emitting surface 31 of the light emitting portion 3 is configured to be as small as possible, and the light utilization efficiency of the optical element of the vehicle lamp is improved.

In an alternative embodiment, the first side 211 may extend along a straight line in the left-right direction, the first side 211 may be a plane, and the projection shape of the boundary 213 between the first side 211 and the second side 212 (i.e., the projection of the boundary on a plane perpendicular to the main optical axis of the light-emitting surface 31) may be a straight line. In practical applications, the cut-off line in the light shape may be a horizontal line when the lamp optical element is applied to a front fog lamp or a steering assist lamp (corner lamp).

As an example, as shown in fig. 4 and 5, the projected shape of the boundary line 213 may be a straight line, i.e., a cut-off line in the light shape may be a horizontal line.

In an alternative embodiment, the first side 211 may extend along a line having an inflection point in the left-right direction, the first side 211 may be a surface including a step, and the projected shape of the boundary line 213 of the first side 211 and the second side 212 (i.e., the projection of the boundary line on a plane perpendicular to the main optical axis of the light-emitting surface 31) may be a line having an inflection point. In practical applications, the cut-off line in the light shape may be a line with an inflection point when the lamp optical element is applied to a low beam lamp.

As an example, as shown in fig. 6, 7, 8, and 9, the projected shape of the boundary line 213 may be a line having an inflection point, that is, a cut-off line in the light shape may be a line having an inflection point. As an example, fig. 18 shows a light shape cut-off line having an inflection point (step).

In alternative embodiments, the second side 212 of the recessed feature 21 may be configured as a planar surface, as shown in fig. 4 and 6. In this case, the projection of the boundary line 213 formed by the first side 211 and the second side 212 in a plan view is a straight line, as shown in fig. 7.

In an alternative embodiment, the second side 212 of the concave structure 21 may be configured as a curved surface protruding towards the light entrance 1. Specifically, the second side 212 may be configured such that light incident on the curved surface gathers in the left-right direction, and the cross section of the second side 212 may be a curve protruding toward the light incident portion 1, as shown in fig. 9. In this case, the boundary 213 between the first side surface 211 and the second side surface 212 is projected as a curve protruding toward the light entrance portion 1 in a plan view, as shown in fig. 12.

In practical application, when the light collecting structures 11 collect light rays simultaneously and pass through one light emitting surface 31, the light blocking structure provided by the embodiment of the present disclosure, which includes the second side 212 having the cross section that is the curve protruding toward the light incident portion 1, can ensure the level of the light spot with a large angle, and thus can realize a relatively wide light shape function with a blocking line structure with a relatively small light emitting opening.

In at least some embodiments of the present disclosure, a low beam three zone structure may be included in a provided vehicle lamp optical element for forming a low beam three zone light shape in a target light shape of the vehicle lamp optical element so that the vehicle lamp optical element meets requirements of regulatory three zones.

Specifically, a low beam three-zone structure may be provided on the upper surface and/or the lower surface of the light passing portion 2 of the lamp optical element.

Alternatively, the low beam three zone structure includes a first low beam three zone structure 22, and the first low beam three zone structure 22 is configured as an outward convex structure or an inward concave structure at the upper surface of the light passing portion 2, as shown in fig. 13. Specifically, the first low beam three zone structure 22 may be configured as an inwardly recessed structure so that light rays projected thereon are deflected toward the upper surface of the light passing portion 2 so as to form a low beam three zone light shape above the light shape cut-off line. It will be appreciated that in actual use, the first low beam three zone structure 22 may also be configured as an outwardly convex structure.

Alternatively, the low beam three zone structure includes a second low beam three zone structure 23, and the second low beam three zone structure 23 is configured as an outward convex structure or an inward concave structure at the lower surface of the light passing portion 2, as shown in fig. 14. Specifically, the second low beam three zone structure 23 may be configured as an inward concave structure so that light rays projected thereto are deflected toward the upper surface of the light passing portion 2 so as to form a low beam three zone light shape above the light shape cut-off line. It will be appreciated that in actual use, the second low beam three zone structure 23 may also be configured as an outwardly convex structure.

Alternatively, the low beam three zone structure includes a third low beam three zone structure 24, the third low beam three zone structure 24 being configured as an outwardly convex structure or an inwardly concave structure at the first side 211, as shown in fig. 15. Specifically, the third low-beam three-zone structure 24 may be configured as an outward convex structure such that light rays projected thereon sequentially exit from the first side 211, enter from the second side 212, and exit from the light-exit surface 31, so as to form a low-beam three-zone light shape above the light shape cutoff line. It will be appreciated that in actual use, the third low beam three zone structure 24 may also be configured as an inwardly concave structure.

In the vehicle lamp optical element provided in the implementation of the present specification, the light exit surface 31 of the light exit portion 3 may alternatively be a continuous curved surface.

When the concave structure 21 is included in the lamp optical element, the focal point of at least one optical lens surface 311 of the plurality of optical lens surfaces 311 may be located near the boundary line 213 in order to achieve a clearer light shape cut-off line.

In practical application, the step pattern surface may include a step fresnel checkered pattern, a step fresnel vertical stripe, a step fresnel horizontal stripe, a step fresnel diamond pattern, a step fresnel polygonal pattern, a step fresnel irregular stripe, and the like, and the type of the step pattern surface is not limited to the examples listed here.

As an example, a stepped fresnel checkerboard pattern is shown as in fig. 16; as in fig. 17, a stepped fresnel vertical stripe is shown.

In the vehicle lamp optical element provided in the embodiment of the present specification, alternatively, the outline of the light-emitting surface 31 of the light-emitting portion 3 may be arbitrarily set according to design requirements. For example, it may be square, circular or any other shape.

In addition, in an alternative implementation, a microstructure pattern may be further disposed on the light-emitting surface 31 of the light-emitting portion 3, for adjusting the cut-off line gradient.

Additionally, in alternative implementations, coatings and/or patterns may be added to the upper and lower sides. Thus, system flare can be optimized.

In addition, in alternative implementations, the upper and lower sides of the lamp optical element provided in the implementations of the present disclosure may be configured to be hidden in the decorative frame or to protrude from the decorative frame according to actual modeling needs.

In embodiments of the present disclosure, the lamp optic may be made of a transparent light guiding material. Alternatively, the transparent light guide material may include PMMA, PC, glass, or the like, without being limited thereto.

For example, although the light exit surface 31 is exemplified as a stepped fresnel vertical stripe in fig. 1 to 15, those skilled in the art will appreciate that a continuous curved surface or other types of stepped pattern surfaces are also possible. For example, while fig. 9, 11 and 12 illustrate a folded lamp optic including the concave structures 21, those skilled in the art will appreciate that the folded lamp optic may not include the concave structures 21; and although the projected shape of the boundary line 213 of the concave structure 21 shown in fig. 9, 11 and 12 is a line having an inflection point, it will be understood by those skilled in the art that the projected shape of the boundary line 213 may be a line having no inflection point; and although fig. 9, 11 and 12 show the projection shape of the second side 212 of the concave structure 21 in such a manner that the line having the inflection point is a curved surface protruding toward the light incident portion 1, it will be understood by those skilled in the art that the second side 212 may be configured as a plane. The examples given herein are not exhaustive.
