[0049] The core of the present invention is to disclose a lighting module to achieve multifunctional integration of lighting modules.

[0050] Another core of the present invention is to disclose a vehicle lamp comprising the above-mentioned lighting module.

[0051] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0052] Combine Figures 1-5 The lighting module disclosed in the present invention includes a light-emitting component, a motion component and an outer lens component, the light-emitting component includes a lamp bead 100 for emitting light; the motion component includes a driving member 200 and a transmission member, the driving member 200 is transmission-connected to the transmission member, and is used to drive the transmission member to switch between a first posture and a second posture; the outer lens component includes a first outer lens 300 and a second outer lens 310, and the first outer lens 300 and the second outer lens 310 have different optical structures, and the first outer lens 300 and the second outer lens 310 are both connected to the transmission member; when the transmission member is in the first posture, the first outer lens 300 is located on the light-emitting path of the lamp bead 100 to form a first light pattern, and the second outer lens 310 avoids the light-emitting path of the lamp bead 100; when the transmission member is in the second posture, the first outer lens 300 avoids the light-emitting path of the lamp bead 100, and the second outer lens 310 is located on the light-emitting path of the lamp bead 100 to form a second light pattern.

[0053] Among them, combinedFigures 6-11 By designing different optical shapes on the inner and outer surfaces of the first outer lens 300 and the second outer lens 310, light can be emitted at different angles, thereby obtaining different light patterns. The first light pattern and the second light pattern are used to meet driving requirements under different road conditions. For example, Figure 12 and Figure 13 , the first light type and the second light type can correspond to general road conditions and urban road conditions respectively.

[0054] The motion assembly is used to drive the first outer lens 300 and the second outer lens 310 to move between an illumination position that forms a light pattern and a retracted position that avoids the light exit path. The motion of the first outer lens 300 and the second outer lens 310 includes, but is not limited to, translation, rotation, and flipping. Specific transmission methods of the motion assembly include, but are not limited to, screw drive, gear drive, and the like.

[0055] Compared with the existing technology, the lighting module disclosed in the present invention moves the position of the first outer lens 300 and the second outer lens 310 through mechanical movement, thereby realizing the switching of the two lighting function modes, increasing the technological sense of the product and the user experience without affecting the shape; at the same time, the lighting device disclosed in the present invention has the advantages of compact structure, light weight, small size, low cost and high precision.

[0056] Specifically, the driving member 200 is a motor. In one embodiment, the transmission member includes a first transmission gear, a second transmission gear, and a rotating device 210. The first transmission gear is in transmission connection with the driving member 200; the second transmission gear meshes with the first transmission gear. The rotating device 210 and the second transmission gear are coaxially arranged and connected, and the first outer lens 300 and the second outer lens 310 are both connected to the rotating device 210. The thickness direction of the first outer lens 300 and the second outer lens 310 are both parallel to the radial direction of the second transmission gear. The thickness directions of the first outer lens 300 and the second outer lens 310 are arranged at a predetermined angle, which is less than or equal to 90 degrees. The thickness directions of the first outer lens 300 and the second outer lens 310 correspond to the incident direction of light on the first outer lens 300 and the second outer lens 310, respectively. Figure 1 and Figure 2 , respectively, show a feasible structure when the preset angle is equal to 90 degrees and the preset angle is less than 90 degrees. When the driving member 200 drives the rotating device 210 to rotate, the first outer lens 300 and the second outer lens 310 can move to the lighting position and the avoidance position respectively.

[0057] The second transmission gear and the rotating device 210 may be an integrated structure. Figure 1 According to actual conditions, the first transmission gear and the driving member 200 can be connected through a screw or a worm.

[0058] In addition, according to the actual layout inside the headlight, the rotating device 210 can be directly connected to the first outer lens 300 and the second outer lens 310 or respectively connected through a connecting rod 220 radially parallel to the second transmission gear to avoid the internal structure of the lamp or the light output component.

[0059] Further, combined with Figure 3 The two connecting rods 220 are connected by a support rod 221 to ensure the reliability of the structure.

[0060] In a specific embodiment disclosed in the present utility model, Figure 5 and Figure 6 The transmission member includes a transmission screw 211 and a transmission nut 212. The transmission screw 211 is in transmission connection with the driving member 200; the transmission nut 212 is threadedly engaged with the transmission screw 211, and the first outer lens 300 and the second outer lens 310 are both connected to the transmission nut 212. Along the extension direction of the transmission screw 211, the first outer lens 300 and the second outer lens 310 are staggered. When the driving member 200 drives the transmission screw 211 to rotate, the transmission nut 212 drives the first outer lens 300 and the second outer lens 310 to translate together, thereby achieving the switching of the light pattern of the lighting module.

[0061] A further optimization scheme is as follows: since the transmission nut 212 drives the first outer lens 300 and the second outer lens 310 to translate synchronously, in order to reduce the influence of the outer lens located in the avoidance position on the light pattern, an avoidance gap is provided between the first outer lens 300 and the second outer lens 310 along the extension direction of the transmission screw 211, and the size of the avoidance gap can be adjusted according to actual conditions.

[0062] The light emitting assembly includes a heat sink 120 and a lamp board 110. The lamp board 110 is arranged on the heat sink 120, and the lamp beads 100 are arranged on the lamp board 110. Figure 1 and Figure 2 Specifically, the lamp bead 100 can emit light through the inner lens 130 or the reflector 140. The light emitted by the lamp bead 100 is focused by the inner lens 130 or reflected by the reflector 140 to form a beam of light in a specific direction, which is then refracted by the outer lens assembly to form a light pattern for vehicle lighting, meeting regulations and driving requirements.

[0063] To ensure the lighting module's heat dissipation, the driver 200 is connected to a heat sink 120, allowing it to dissipate heat from both the driver 200 and the light board 110. Specifically, the heat sink 120 can be a finned heat sink. If a cooling fan is also installed within the vehicle lamp, the fan's air outlet is directed toward the driver 200 and the light board 110 for air cooling and heat dissipation.

[0064] Further optimization scheme, in one embodiment, the outer lens assembly also includes a third outer lens, and the optical structure of the third outer lens is different from that of the first outer lens 300 and the second outer lens 310. The third outer lens is connected to the transmission member, and the driving member 200 is used to drive the transmission member to switch between the first position, the second position and the third position; when the transmission member is in the first position or the second position, the third outer lens avoids the light emitting path of the lamp bead 100; when the transmission member is in the third position, the first outer lens 300 and the second outer lens 310 avoid the light emitting path of the lamp bead 100, and the third outer lens is located on the light emitting path of the lamp bead 100 to form a third light pattern.

[0065] According to actual needs, the number of outer lenses may not be limited to the two and three mentioned above. The present invention can achieve a variety of different light-type lighting effects by carrying at least two outer lenses and replacing different outer lenses through a motion assembly.

[0066] In order to ensure uniformity of light output, optical patterns are provided on the light incident surface and / or light exit surface of the first outer lens 300 , and optical patterns are provided on the light incident surface and / or light exit surface of the second outer lens 310 .

[0067] The vehicle lamp disclosed in the present invention includes the above-mentioned lighting module, and therefore also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and are not described in detail here.

[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated in part or in whole into another embodiment, unless expressly excluded by another embodiment.
