[0020] The technical solution of the present disclosure is explained in further detail below by means of embodiments, in conjunction with the drawings. Herein, identical or similar reference labels indicate identical or similar components. The following explanation of embodiments of the present disclosure with reference to the drawings is intended to explain the general invention concept of the present disclosure, and should not be interpreted as a limitation of the present disclosure.

[0021] In addition, in the following detailed description, to facilitate explanation, many specific details are expounded to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments may also be implemented without these specific details. In other cases, well-known structures and apparatuses are illustratively embodied to simplify the accompanying drawings.

[0023] The present invention discloses an optical module 100. As shown in Figs. 1 and 2, the optical module 100 comprises: a light source (not shown), configured to emit light; a reflector 102, configured to reflect light from the light source; a lens 103, configured to project light reflected by the reflector 3; and a heat sink 104, having a first surface 1041 and a second surface 1042 opposite the first surface 1041, the first surface 1041 being configured to have the light source 101 and the reflector 103 installed thereon, and the second surface 1042 being provided with a first hole 1051 and a second hole 1052, the first hole 1051 and the second hole 1052 being configured to be used for fixing or adjusting the optical module 100 in the vertical direction. Those skilled in the art will know that the vertical direction denotes the height direction of the motor vehicle.

[0024] As a result of providing an adjustment structure on the optical module in the above-described technical solution of the present invention, there is no need to provide an additional vertical adjustment support for adjusting the relative positions of optical modules in the vertical direction, so the number of components used is reduced, the amount of space occupied by the lighting device is reduced, the assembly process is simplified, and costs are reduced. Furthermore, in cases where the optical module does not require vertical adjustment, the design of the present application can also be used for fixing the optical module in the vertical direction.

[0025] The first hole 1051 and the second hole 1052 are arranged near the lens 103 of the optical module 100.

[0026] Specifically, as shown in Figs. 3 and 4, a line connecting the first hole 1051 and the second hole 1052 is substantially perpendicular to the light output direction of the optical module 100. When performing adjustment in the vertical direction, the line connecting the first hole 1051 and the second hole 1052 may be used as an axis of upward / downward rotation of the optical module 100. In other examples, the line connecting the first hole 1051 and the second hole 1052 may be arranged at an angle to the light output direction of the optical module 10, and the present application imposes no specific restrictions in this respect.

[0027] In an example, as shown in Figs. 3 and 4, the second surface 1042 of the heat sink is further provided with a third fixing hole 1053, the third fixing hole 1053 being arranged at the side of the first hole 1051 and second hole 1052 that is remote from the lens 103. That is, the third fixing hole 1053 is arranged in a rear region of the optical module 100 in the light output direction thereof. As a result of providing three fixing holes, the optical module 100 can be fixed on a support 106 directly, without the need for an additional fixing structure.

[0028] The first hole 1051 and second hole 1052 and the third fixing hole 1053 are connected to the support 106 of the optical module 100 by screws. The use of screws for fixing in the above-described technical solution of the present invention can ensure a flexible connection between the support and the optical module, while also ensuring stability of connection. In other examples, the support 106 may be fixed to the optical module 100 in other ways, and the present invention imposes no specific restrictions in this respect.

[0029] In another example, as shown in Figs. 3 and 4, the second surface 1042 of the heat sink is further provided with an adjustment hole 1054, the adjustment hole 1054 being arranged at the side of the first hole 1051 and second hole 1052 that is remote from the lens 103. That is, the adjustment hole 1054 is arranged in a rear region of the optical module 100 in the light output direction thereof. The adjustment hole 1054 is used for installing an adjusting means 1057 to drive the optical module 100 to rock up and down in the vertical direction about an axis. As a result of providing the adjustment structure on the optical module 100, there is no need to provide an additional vertical adjustment support, so the amount of space occupied by the optical module is reduced effectively.

[0030] Specifically, the first hole 1051 and second hole 1052 are connected to the support 106 of the optical module 100 by a ball-and-socket connection. As shown in Figs. 2 and 4, a first ball head 1055 and a second ball head 1056 are mounted in the first hole 1051 and the second hole 1052, and the support 106 of the optical module 100 is correspondingly provided with a first ball socket 1058 and a second ball socket 1059. The use of a ball-and-socket connection to connect the optical module to the support enables the optical module to rotate about the axis smoothly when adjustment is performed. Optionally (not shown in the drawings), it is also possible for a first ball socket 1058 and a second ball socket 1059 to be mounted in the first hole 1051 and the second hole 1052, while the support 106 of the optical module 100 is correspondingly provided with a first ball head 1055 and a second ball head 1056. In other examples, the optical module 100 and the support may be connected in any suitable way, as long as it is ensured that the optical module is able to rotate smoothly when adjustment is performed.

[0031] When the adjusting means 1057 is driven, the adjusting means 1057 drives the support 106 and the optical module 100 to rock up and down in the vertical direction. In other examples, the present application imposes no specific restrictions on the choice of adjusting means, as long as it is ensured that when the adjusting means 1057 is driven, the optical module can be driven to rotate smoothly.

[0032] The support 106 according to the present application is preferably part of the overall adjustment structure of the light-emitting device, and may also be a supporting structure for the optical module.

[0033] In an example, the second surface 1042 of the heat sink is provided with both the third fixing hole 1053 and the adjustment hole 1054. With such a configuration, the optical module can be fixed or vertically adjusted as needed, so the same optical module can be matched to different lighting device designs, thus increasing the range of applications of the optical module. Specifically, the third fixing hole 1053 and the adjustment hole 1054 may be arranged adjacent to each other, or have their positions adjusted flexibly according to heat sink and light-emitting module layout requirements, and the present application imposes no specific restrictions in this respect.

[0034] The optical module according to the present invention may be used for fine adjustment relative to another module in the vertical direction, or may be a high-beam module or a low-beam module.

[0035] As a result of providing the adjustment structure on the optical module according to the present invention, there is no need to provide an additional vertical adjustment support for adjusting the relative positions of optical modules in the vertical direction, so the number of components used is reduced, the amount of space occupied by the lighting device is reduced, the assembly process is simplified, and costs are reduced. Furthermore, in cases where the optical module does not require vertical adjustment, the design of the present application can also be used for fixing the optical module in the vertical direction. The same optical module can be matched to different lighting device designs, thus increasing the range of applications of the optical module.

[0036] According to an embodiment of the present invention, a lighting device is also included, which comprises any one of the optical modules described above.

[0037] According to an embodiment of the present invention, a motor vehicle is further included, which comprises the abovementioned lighting device.

[0038] The motor vehicle according to the present invention at least has the beneficial effects of the lighting device for motor vehicles as described above.

[0039] Those skilled in the art should understand that all the embodiments described above are exemplary. In addition, those skilled in the art can improve them. The structures described in various embodiments can be freely combined without a conflict in structure or in principle.

[0040] Although the present invention has been explained in conjunction with the drawings, the embodiments disclosed in the drawings are intended to provide an illustrative description of preferred embodiments of the present invention, and cannot be interpreted as a limitation of the present invention.

[0041] Although some embodiments of the concept of the present disclosure have been shown and described, those ordinarily skilled in the art will understand that changes can be made to these embodiments without departing from the principle and spirit of the general concept of the present invention. The scope of the present invention is defined by the claims and their equivalents.
