TECHNICAL FIELD
[0001] The present application relates to the technical field of vehicle lamps, in particular to an integrated lighting module and vehicle lamp. BACKGROUND
[0002] With the development of vehicle lamp lighting technology, vehicle manufacturers have no longer been satisfied with the single lighting function of the vehicle lighting system, but have begun to pursue its role in decoration. For example, installing an atmosphere lamp on the side wall of the vehicle headlamp or the side wall of the decorative frame makes the headlamp look brighter in the non-illumination state, that is, the state where the headlamp does not perform the illumination function, due to the lighting of the atmosphere lamp on the side wall of the headlamp or the side wall of the decorative frame, thereby playing a decorative role for the vehicle.
[0003] However, since the traditional atmosphere lamp is usually designed on the side wall of the lighting module or the side wall of the decorative frame, a bright spot is often formed on the outer lens of the lighting module, which is easy to cause glare to the human eye. In order to avoid causing glare to the human eye, the irradiation area of the atmosphere lamp inside the lighting module is usually set on the ground, but this requires the person to crouch down or look straight at the vehicle lamp to be able to perceive whether the atmosphere lamp is lit or not, and the light spot reflected by the atmosphere lamp on the surface of the outer lens of the lighting module is still uneven, which is easy to form a bright spot, affecting the experience.

DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

It should be understood that the terms used in this way can be interchanged under appropriate circumstances, and this is only a distinguishing way used in the description of the embodiments of the present application to describe the objects of the same attribute. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, so that the processes, methods, systems, products or equipment containing a series of units do not have to be limited to those units, but can include other units not clearly listed or inherent to these processes, methods, products or equipment.
[0036] As described in the background section, since the conventional atmosphere lamp is usually designed on the side wall of the lighting module or the side wall of the trim, a bright spot is often formed on the outer lens of the lighting module, which is easy to cause glare to the human eye. In order to avoid glare to the human eye, the illumination area of the atmosphere lamp inside the lighting module is usually set on the ground, but this requires the person to squat or look straight at the car light to detect whether the atmosphere lamp is lit, and the light spot on the surface of the outer lens of the lighting module is still uneven, which is easy to form a bright spot and affect the experience.
[0037] In view of this, embodiments of this application provide an integrated lighting module. Figure 1 A schematic diagram of the structure of an integrated lighting module provided in an embodiment of this application is shown, as follows: Figure 1 As shown, the integrated lighting module includes a light source module 10, an inner lens 20, and an outer lens 30 arranged sequentially along the optical path transmission direction X.
[0038] like Figure 1 As shown, the light source module 10 includes a first light source module 11 and a second light source module 12. The inner lens 20 has a surface S1 away from the light source module 10, which includes a first light-emitting surface area S11 and a second light-emitting surface area S12. The first light source module 11 and the first light-emitting surface area S11 are correspondingly arranged, and the second light source module 12 and the second light-emitting surface area S12 are correspondingly arranged.
[0039] Thus, the light emitted by the first light source module 11 passes through the first light-emitting surface area S11 and then through the outer lens 30 to form a near beam pattern and / or a far beam pattern. That is, the first light source module 11, the first light-emitting surface area S11, and the outer lens 30 constitute a near beam illumination module, a far beam illumination module, or a combination of near and far beam illumination modules.
[0040] And, as Figure 1 As shown, the light emitted by the second light source module 12 passes through the second light-emitting surface area S12 and then through the outer lens 30 to form parallel light rays. The second light source module 12, the second light-emitting surface area S12, and the outer lens 30 constitute an ambient light.
[0041] It is understandable that the surface of the inner lens 20 facing the light source module 10, i.e., the light incident surface of the inner lens 20, can be a plane. The first light emitting surface area S11 of the inner lens 20 adjusts the light emitted from the first light source module 11. The first light emitting surface area S11 of the inner lens 20, together with the outer lens 30, adjusts the light emitted from the first light source module 11 to obtain near beam and / or far beam patterns. Similarly, the second light emitting surface area S12 of the inner lens 20 adjusts the light emitted from the second light source module 12. The second light emitting surface area S12 of the inner lens 20, together with the outer lens 30, adjusts the light emitted from the second light source module 12 to form parallel light rays emitted by the ambient light.
[0042] It is also understandable that the light emitted by the second light source module 12, after passing through the second light-emitting surface area S12 of the inner lens 20, is converged into parallel light by the outer lens 30 and projected out. This parallel light can be completely parallel or approximately parallel. The parallel light can form a uniform light shape, so that the ambient light can emit a relatively uniform light spot.
[0043] It can be seen that the integrated lighting module provided by the embodiment of the present application sets the second light-emitting surface area S12 on the inner lens 20 of the lighting module, and shares the outer lens 30 with the lighting module, thereby integrating the atmosphere lamp in the lighting module, sharing at least the inner lens 20 and the outer lens 30 with the lighting module, and the light emitted by the atmosphere lamp is parallel light formed after the light emitted by the second light source module 12 sequentially passes through the second light-emitting surface area S12 of the inner lens 20 and the outer lens 30, so that the atmosphere lamp can emit a relatively uniform light spot, and it is convenient for the human eye to observe, and the experience is improved. In addition, the atmosphere lamp is designed in an integrated manner with the lighting module, which not only realizes the integration of different functions in the same module, but also can reduce the number of parts and the weight of the whole module, which meets the energy saving and carbon neutralization concept.
[0044] The integrated lighting module provided by the embodiment of the present application has low-beam and / or high-beam lighting function and atmosphere lamp function. When the lighting function is realized, the atmosphere lamp function is not realized, and when the atmosphere lamp function is realized, the lighting function is not realized, that is, the lighting function and the atmosphere lamp function act at different times.
[0045] It can be understood that when the first light source module 11, the first light-emitting surface area S11 of the inner lens 20 and the outer lens 30 are designed to meet the formation of low-beam light shape and / or high-beam light shape, the outer lens 30 is fixed, and then the second light source module 12 and the second light-emitting surface area S12 of the inner lens 20 can be adjusted, including adjusting the relative position of the second light source module 12 and the inner lens 20 and the diffusion and contraction effect of the second light-emitting surface area S12 of the inner lens 20 on the light emitted by the second light source module 12, thereby adjusting the position and size of the light spot emitted by the atmosphere lamp.
[0046] Optionally, in some embodiments of the present application, as shown in Figure 1 The second light-emitting surface area S12 of the inner lens 20 is designed so that the light emitted by the second light source module 12 diffuses along the first direction Y and the second direction Z, and then transmits through the surface of the outer lens 30 away from the inner lens 20, the first direction Y and the second direction Z are perpendicular, and the first direction Y and the second direction Z are both perpendicular to the light path transmission direction X.
[0047] It is understood that the second light source module 12 may include one or more LED (Light Emitting Diode) light sources. An LED light source can be approximated as a point light source, where the emitted light spot is bright in the center and dark around the edges. In this embodiment, the second light-emitting surface area S12 of the inner lens 20 is designed such that the light emitted by the second light source module 12 diffuses along the first direction Y and along the second direction Z. Specifically, the second light-emitting surface area S12 of the inner lens 20 is designed such that the brighter light emitted from the central area of the LED light source in the second light source module 12 diffuses along the first direction Y and along the second direction Z. The first direction Y can be understood as the horizontal direction, i.e., the transverse direction, and the second direction Z can be understood as the vertical direction, i.e., the longitudinal direction. In other words, the second light-emitting surface area S12 of the inner lens 20 is designed to have vertical, horizontal, and transverse directions. The characteristic of the light source in the second light source module 12 to diffuse the bright light in the central area emitted by the LED light source in the second light source module 12 is that the bright light in the central area emitted by the LED light source in the second light source module 12 is diffused into divergent light after passing through the second light-emitting surface area S12 of the inner lens 20. This is equivalent to converting the LED light source (point light source) in the second light source module 12 into a surface light source corresponding to the second light-emitting surface area S12 of the inner lens 20. Then, the light emitted from this surface light source passes through the outer lens 30 and moves away from the surface of the inner lens 20 (i.e., the light-emitting surface of the outer lens 30), thereby forming a relatively uniform bright spot on the light-emitting surface of the outer lens 30.
[0048] Further optional, in some embodiments of this application, reference is made to Figure 1 As shown, along the light path transmission direction X, the distance between the second light-emitting surface region S12 of the inner lens 20 and the focal plane of the outer lens 30 is less than a preset distance. Considering that the second light-emitting surface region S12 of the inner lens 20 can be a curved surface, the distance between the second light-emitting surface region S12 of the inner lens 20 and the focal plane of the outer lens 30 is set to be less than a preset distance along the light path transmission direction X. That is, the second light-emitting surface region S12 of the inner lens 20 is set near the focal plane of the outer lens 30, so that the light emitted by the second light source module 12 passing through the second light-emitting surface region S12 of the inner lens 20 can cover the entire surface of the outer lens 30 away from the inner lens 20 (i.e., the entire light-emitting surface of the outer lens 30). This results in a more uniform bright spot on the light-emitting surface of the outer lens 30, and the bright spot of the outer lens 30 is relatively uniform when viewed from different angles, improving the perceived fineness of the outer lens 30.
[0049] In this embodiment, the preset distance is not limited, and the preset distance can be set according to the actual situation.
[0050] Figure 2 It shows Figure 1 A schematic diagram showing the inner lens 20 facing away from the surface S1 of the light source module 10 in the integrated lighting module.Figure 3 Further shown Figure 2 An enlarged schematic view of the portion of the dashed oval is shown in FIG. 3B, and Figure 2 and Figure 3 As shown in FIG. 3B, in some embodiments of the present application, the first light-emitting surface region S11 includes a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y, and the second light-emitting surface region S12 includes a plurality of second sub-light-emitting surfaces R2 arranged along the first direction Y.
[0051] It can be understood that, since the low beam light pattern and the high beam light pattern are both laterally wide and longitudinally narrow light patterns, the first light-emitting surface region S11 of the inner lens 20 is arranged to include a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y (i.e., along the lateral direction) so as to form a laterally wide and longitudinally narrow low beam light pattern and / or a laterally wide and longitudinally narrow high beam light pattern.
[0052] It can be understood that, since the low beam light pattern and the high beam light pattern are both laterally wide and longitudinally narrow light patterns, the first light-emitting surface region S11 of the inner lens 20 is arranged to include a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y (i.e., along the lateral direction) so as to form a laterally wide and longitudinally narrow low beam light pattern and / or a laterally wide and longitudinally narrow high beam light pattern.
[0053] It can be understood that, since the low beam light pattern and the high beam light pattern are both laterally wide and longitudinally narrow light patterns, the first light-emitting surface region S11 of the inner lens 20 is arranged to include a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y (i.e., along the lateral direction) so as to form a laterally wide and longitudinally narrow low beam light pattern and / or a laterally wide and longitudinally narrow high beam light pattern.
[0054] It can be understood that, since the low beam light pattern and the high beam light pattern are both laterally wide and longitudinally narrow light patterns, the first light-emitting surface region S11 of the inner lens 20 is arranged to include a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y (i.e., along the lateral direction) so as to form a laterally wide and longitudinally narrow low beam light pattern and / or a laterally wide and longitudinally narrow high beam light pattern.
[0055] Optionally, the second sub-light-emitting surface R2 can be a cylindrical surface, and each second sub-light-emitting surface R2 can be the same cylindrical surface. In this way, while making the light emitted by the second light-emitting surface area S12 of the inner lens 20 diffuse along the first direction Y (i.e., along the lateral direction) and along the second direction Z (i.e., along the longitudinal direction) of the light emitted by the second light source module 12, the design of the second light-emitting surface area S12 of the inner lens 20 is simple and easy to implement.
[0056] Furthermore, it can be understood that the first light-emitting surface area S11 of the inner lens 20 includes a plurality of first sub-light-emitting surfaces R1 arranged along the first direction Y (i.e., along the transverse direction), and the second light-emitting surface area S12 of the inner lens 20 includes a plurality of second sub-light-emitting surfaces R2 arranged along the first direction Y (i.e., along the transverse direction). The arrangement of the first light-emitting surface area S11 and the second light-emitting surface area S12 along the second direction Z (i.e., along the longitudinal direction) on the light-emitting surface of the inner lens 20 is beneficial to reducing the volume of the inner lens 20, thereby reducing the overall volume of the integrated lighting module.
[0057] Optionally, in other embodiments of this application, the first light-emitting surface region S11 and the second light-emitting surface region S12 can also be arranged along the first direction X (i.e., along the lateral direction) on the light-emitting surface of the inner lens 20. In this way, the volume of the inner lens 20 and the overall volume of the corresponding integrated lighting module will be increased accordingly.
[0058] Further, optionally, in some embodiments of this application, in combination with Figures 1-3 As shown, the first light source module 11 includes a plurality of first LED light sources D1 arranged along the first direction Y (i.e., along the lateral direction). The first LED light sources D1 are arranged in a one-to-one correspondence with the first sub-light-emitting surface R1, so that the light emitted by each first LED light source D1 passes through the corresponding first sub-light-emitting surface R1 and is then emitted from the outer lens 30 to form a near beam pattern and / or a far beam pattern.
[0059] Combination Figures 1-3 As shown, the second light source module 12 includes at least two second LED light sources D2 arranged along the first direction Y (i.e., along the lateral direction), and the second LED light sources D2 are configured to correspond to a second sub-light-emitting surface R2 or to at least two second sub-light-emitting surfaces R2.
[0060] Because the regulations for low beam and high beam patterns are relatively strict, the first LED light source D1 is set to correspond one-to-one with the first sub-light-emitting surface R1 to form low beam and / or high beam patterns. However, the requirements for the light spot emitted by the ambient light are relatively low. Therefore, the second LED light source D2 can be set to correspond to one second sub-light-emitting surface R2, or the second LED light source D2 can be set to correspond to at least two second sub-light-emitting surfaces R2.
[0061] It can be understood that each first LED light source D1 in the first light source module 11 can be independently controlled, so that when the first light source module 11, the first light emitting surface area S11 of the inner lens 20 and the outer lens 30 constitute a low beam lighting module, the adaptive low beam function can be achieved; when the first light source module 11, the first light emitting surface area S11 of the inner lens 20 and the outer lens 30 constitute a high beam lighting module, the adaptive high beam function can be achieved; when the first light source module 11, the first light emitting surface area S11 of the inner lens 20 and the outer lens 30 constitute a high and low beam lighting module, the adaptive high and low beam function can be achieved; that is, the lighting module can automatically adjust the on-off of some LED light sources according to the speed of the vehicle, the steering angle, the road conditions and the environmental light, and then adjust the illumination range of the lighting module.
[0062] It can also be understood that each second LED light source D2 in the second light source module 12 can be independently controlled or not independently controlled, that is, it can also be controlled as a whole. Moreover, the light intensity of each second LED light source D2 is adjusted by adjusting the current size of each second LED light source D2 in the second light source module 12, and then the light intensity of the light spot projected by the atmosphere lamp is adjusted, so that multiple lighting states of different brightness of the atmosphere lamp can be realized.
[0063] Optionally, as shown in Figure 1 , the first LED light source D1 and the second LED light source D2 can be integrated on the same PCB board 13, that is, the first light source module 11 and the second light source module 12 can be integrated on the same PCB board 13, so that the first light source module 11 and the second light source module 12 can share the wire harness and the control circuit, which can further reduce the volume and weight of the integrated lighting module and improve the integration degree of the integrated lighting module.
[0064] Of course, other options, as shown in Figure 4 , Figure 4 Another structure schematic diagram of the integrated lighting module provided by the embodiment of the application is shown, it can be seen that the first LED light source D1 and the second LED light source D2 can also be integrated on two PCB boards 13, so that the second light source module 12 can be arranged closer to the inner lens than the first light source module 11 along the light path transmission direction X.
[0065] This is because lighting modules that form near-beam and / or high-beam patterns typically require relatively high power LED light sources, while ambient lights require relatively low power LED light sources. In other words, the first LED light source D1 has relatively high power, while the second LED light source D2 has relatively low power. Along the light path transmission direction X, the second light source module 12 is positioned closer to the inner lens than the first light source module 11. That is, the first LED light source D1 in the first light source module 11 is relatively farther from the inner lens 20, preventing the high-power first LED light source D1 from damaging the inner lens 20. Furthermore, the second LED light source D2 in the second light source module 12 is relatively closer to the inner lens 20, which can improve the brightness of the light spot emitted by the ambient light and increase the light utilization rate of the second light source module 12.
[0066] In the above embodiments, the first light source module 11 and the second light source module 12 are mainly arranged independently, and the first light-emitting surface region S11 and the second light-emitting surface region S12 of the inner lens 20 are arranged independently, as examples for description. Optionally, in other embodiments of this application, such as Figure 5 and Figure 6 As shown, Figure 5 This illustration shows a structural schematic diagram of another integrated lighting module provided in an embodiment of this application. Figure 6 It shows Figure 5 The schematic diagram of the integrated lighting module showing the inner lens 20 facing away from the surface S1 of the light source module 10 shows that the first light-emitting surface region S11 includes multiple third sub-light-emitting surfaces R3 arranged along the first direction Y (i.e., along the lateral direction), and the second light-emitting surface region S12 includes a portion of the third sub-light-emitting surfaces R3. That is, the second light-emitting surface region S12 is a part of the first light-emitting surface region S11. At the same time, the first light source module 11 includes multiple third LED light sources D3 arranged along the first direction Y (i.e., along the lateral direction), and the second light source module 12 includes a portion of the third LED light sources D3. That is, the second light source module 12 includes a portion of the LED light sources in the first light source module 11. The third LED light sources D3 can be controlled independently.
[0067] Thus, similar to the aforementioned embodiments, the first light source module 11 includes each third LED light source D3, the first light-emitting surface area S11 of the inner lens 20, and the outer lens 30 to form an illumination module. The light emitted by each third LED light source D3 in the first light source module 11 passes through the first light-emitting surface area S11 and then through the outer lens 30 to form a near beam and / or a high beam pattern. Furthermore, each third LED light source D3 can be independently controlled so that the brightness of some third LED light sources D3 can be automatically adjusted according to factors such as vehicle speed, steering angle, road conditions, and ambient light, thereby adjusting the illumination range of the illumination module.
[0068] The second light source module 12 includes each third LED light source D3, the second light emitting surface area S12 of the inner lens 20 and the outer lens 30, and forms an atmosphere lamp. The light emitted by each third LED light source D3 in the second light source module 12 passes through the second light emitting surface area S12 and then the outer lens 30, forming a parallel light spot projected by the atmosphere lamp. Each third LED light source D3 can be independently controlled. The light intensity of each third LED light source D3 can be adjusted by adjusting the current of each third LED light source D3 in the second light source module 12, and then the light intensity of the light spot projected by the atmosphere lamp can be adjusted. In this way, multiple lighting states of different brightness of the atmosphere lamp can be realized.
[0069] Different from the foregoing embodiments, the second light emitting surface area S12 is part of the first light emitting surface area S11. In this way, the volume and weight of the inner lens 20 can be further reduced, and then the volume and weight of the integrated lighting module can be further reduced.
[0070] Different from the foregoing embodiments, the second light source module 12 includes part of the LED light sources in the first light source module 11.
