DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In order to meet the regulatory requirements for automotive lighting, the low beam type needs to have a bright and dark cut-off line. Currently, this is usually achieved by setting a shading plate with a cut-off line structure in the light path of the low beam module. At this time, the maximum luminous flux of the low beam type (E max The value is located below the HV point. Since the high beam module does not have a shading plate structure in the light path, when the high and low beam modules are turned on at the same time, the high and low beam light patterns are superimposed, resulting in E max The value is not at the HV point, but below the HV point, and then the high and low beam light pattern connection appears "eccentric", that is, when the light pattern is projected on the light distribution screen, it can be clearly felt that the bright spot deviates from the HV point. This situation can easily cause the driver's perspective to be confused during actual driving and cause accidents. It should be noted that the light distribution screen generally refers to a vertical screen set 25 meters in front of the vehicle, and the light distribution screen has an HV coordinate axis, and the intersection of the H axis and the V axis is the HV point.

[0035] In order to solve the above technical problems, an embodiment of the present application provides a lighting module 100.

[0036] Reference Figure 1 , Figure 2 as well as Figure 3As shown, the lighting module 100 provided in the embodiment of the present application includes a heat dissipation body 101, a high beam module 102 and a low beam module 103, the heat dissipation body 101 respectively has a first area 104 connected to the high beam module 102 and a second area 105 connected to the low beam module 103; the first area 104 is provided with a high beam shading structure 106 extending from the heat dissipation body 101, the high beam shading structure 106 is arranged in the light path of the high beam module 102, and the edge of the high beam shading structure 106 away from the heat dissipation body 101 is arranged to be aligned with the high beam cut-off line Corresponding to the high beam cut-off line structure 1081, the high beam shading structure 106 is used to block part of the light from the high beam module 102 to form a high beam cut-off line; the second area 105 is provided with a low beam shading structure 107 extending from the heat dissipation body 101, and the low beam shading structure 107 is arranged in the light path of the low beam module 103, and the edge of the low beam shading structure 107 away from the heat dissipation body 101 is set as a low beam cut-off line structure 1082 corresponding to the low beam cut-off line, and the low beam shading structure 107 is used to block part of the light from the low beam module 103 to form a low beam cut-off line.

[0037] It should be noted that the high-beam shading structure 106 , the low-beam shading structure 107 and the heat dissipation body 101 are made of the same material and are integrally formed.

[0038] By integrally forming the high-beam shading structure 106, the low-beam shading structure 107, and the heat dissipation body 101, the shading plate separately provided in the prior art can be reduced, which is conducive to optimizing the assembly process, reducing an assembly process, and eliminating the tolerance generated by the assembly process. In addition, since the high-beam shading structure 106 and the low-beam shading structure 107 are arranged in front of the light source, they also have the function of shielding the direct light from the light source to avoid the formation of stray light.

[0039] It should be noted that, in order to facilitate light distribution and achieve better connection between the high beam and low beam patterns, the high beam module 102 is usually arranged "inverted" relative to the low beam module 103, that is, the high beam module 102 and the low beam module 103 are respectively installed on both sides of the heat dissipation body 101, so the first area 104 and the second area 105 are respectively divided on both sides of the heat dissipation body 101 for installing the high beam module 102 and the low beam module 103. Of course, the high beam module 102 and the low beam module 103 can also be installed on the same side of the heat dissipation body 101. The present application does not limit the specific arrangement of the high beam module 102 and the low beam module 103, as long as both have a light shielding structure.

[0040] The high beam shading structure 106 and the low beam shading structure 107 can respectively block part of the light generated by the high beam module 102 and the low beam module 103 . It should be noted that the part of the light is specifically the light in the optical path of the high beam module 102 and the light in the optical path of the low beam module 103 .

[0041] In addition, refer to Figure 3 As shown, the edge of the high beam shading structure 106 away from the heat dissipation body 101 is a high beam cut-off line structure 1081, and the edge of the low beam shading structure 107 away from the heat dissipation body 101 is a low beam cut-off line structure 1082. The high beam cut-off line structure 1081 is arranged corresponding to the low beam cut-off line structure 1082, so that when the high beam light pattern and the low beam light pattern are superimposed, the high beam cut-off line and the low beam cut-off line can also be better connected.

[0042] It should be noted that the first area 104 and the second area 105 have a height difference in the vertical direction, so that the high-beam cutoff line structure 1081 on the high-beam shading structure 106 and the low-beam cutoff line structure 1082 on the low-beam shading structure 107 can correspond to each other, and when the high-beam light pattern and the low-beam light pattern are superimposed, the high-beam cutoff line and the low-beam cutoff line can also be better connected. Fig. 9 This is the light pattern formed by the superposition of high and low beams in the embodiment of the present application.

[0043] The lighting module 100 provided in the embodiment of the present application includes a heat dissipation body 101, a high beam module 102 and a low beam module 103. The heat dissipation body 101 has a first area 104 connected to the high beam module 102 and a second area 105 connected to the low beam module 103. The first area 104 is provided with a high beam shading structure 106 extending from the heat dissipation body 101. The high beam shading structure 106 is arranged in the optical path of the high beam module 102. The edge of the high beam shading structure 106 away from the heat dissipation body 101 is arranged to correspond to the high beam cut-off line. A high beam cut-off line structure 1081 and a high beam shading structure 106 are used to block part of the light from the high beam module 102 to form a cut-off line of the high beam light type; the second area 105 is provided with a low beam shading structure 107 extending from the heat dissipation body 101, and the low beam shading structure 107 is arranged in the light path of the low beam module 103, and the edge of the low beam shading structure 107 away from the heat dissipation body 101 is arranged as a low beam cut-off line structure 1082 corresponding to the low beam cut-off line, and the low beam shading structure 107 is used to block part of the light from the low beam module 103 to form a low beam cut-off line. Compared with the prior art, the edge of the high beam shading structure 106 of the present application away from the heat dissipation body 101 and the edge of the low beam shading structure 107 away from the heat dissipation body 101 correspond to form a high beam cut-off line structure 1081 and a low beam cut-off line structure 1082, respectively, so that the high beam light type and the low beam light type have corresponding high beam cut-off lines and low beam cut-off lines. After the high beam light type and the low beam light type are superimposed, not only the high beam light type and the low beam light type are better connected, but also the E of the superimposed light type is better. maxThe value is at the HV point, which avoids the "eccentricity" of the connection between the high and low beam light patterns, so that there is a better lighting effect when driving at night, and avoids accidents caused by the driver's confusion of perspective. Moreover, since the high beam shading structure 106 and the low beam shading structure 107 are both integrally formed with the heat dissipation body 101, the shading plate separately set in the prior art can be reduced, which is conducive to optimizing the assembly process, reducing an assembly process, and eliminating the tolerance generated by the assembly process. In addition, since the high beam shading structure 106 and the low beam shading structure 107 are arranged in front of the light source, they also have the function of blocking the direct light of the light source to avoid the formation of stray light.

[0045] Specifically, when the high beam module 102 and the low beam module 103 are respectively mounted on both sides of the heat dissipation body 101, in the top view, the arrangement of the lighting modules is as follows: Figure 5 As shown, the high beam mounting surface 109 is located on the lower side of the heat dissipation body 101, the low beam mounting surface 110 is located on the upper side of the heat dissipation body, the high beam shading structure 106 extends downward from the heat dissipation body 101, and the low beam shading structure 107 extends upward from the heat dissipation body 101, and the sum of the height of the high beam shading structure 106 in the vertical direction and the height of the low beam shading structure 107 in the vertical direction is equal to the height difference between the high beam mounting surface 109 and the low beam mounting surface 110, so that the low beam cut-off line and the high beam cut-off line are better connected.

[0046] The specific vertical heights of the high-beam shading structure 106 and the low-beam shading structure 107 can be set by those skilled in the art as required, and are not particularly limited thereto.

[0047] For example, the vertical heights of the high beam shading structure 106 and the low beam shading structure 107 are both about 10 cm, and the height difference between the high beam mounting surface 109 and the low beam mounting surface 110 is about 20 cm.

A lens light incident surface 114 is correspondingly arranged on the lens 112, and light is incident on the lens light incident surface 114 through the light output channel.

[0053] Furthermore, in the embodiment of the present application, partitions 113 are arranged at intervals on the heat dissipation body 101, and the partitions 113 are integrally formed with the heat dissipation body 101. Adjacent partitions 113 can form a plurality of spaced-apart light output channels. The lens 112 has a lens light incident surface 114 arranged corresponding to the light output channels, so that light in each light output channel does not cross-talk.

[0054] Furthermore, the lens light incident surface 114 may be a cylindrical surface having a unidirectional collimation function for light, and can collimate the high beam and the low beam in the horizontal direction.
