[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] As described in the background technology section, existing vehicle lighting modules are large in size and each lighting module is independently designed. The structure, size and appearance of each lighting module vary greatly, and different lighting modules cannot use common parts, resulting in a high cost for the overall vehicle lighting system and the need to stock a large number of different lighting modules, which is not environmentally friendly.

[0046] In view of this, an embodiment of the present application provides a lighting module, which includes at least two lighting units 100. Figure 1 and Figure 2 Schematic diagrams of the structure of a lighting unit 100 in the lighting module provided in the embodiment of the present application under two viewing angles are shown respectively, as shown in FIG. Figure 1 and Figure 2 As shown, the lighting unit 100 includes a light source 10, an inner lens 20 and an outer lens 30 which are arranged in sequence.

[0047] In order to better understand this application, Figure 3 FIG. 1 shows a schematic diagram of the light path transmission of the lighting unit 100 in the lighting module provided in the embodiment of the present application. Figure 3As shown, in the lighting unit 100, the light emitted by the light source 10 is converged by the inner lens 20, incident on the outer lens 30, and then projected into a sub-target light shape by the outer lens 30. Among them, the focus F1 of the inner lens 20 is located on the side of the light source 10 away from the inner lens 20, so that the inner lens 20 can converge as much light emitted by the light source 10 as possible to the outer lens 30, thereby improving the optical efficiency.

[0048] As a comparison, Figure 4 A schematic diagram of light path transmission of an existing lighting module is shown in FIG. Figure 4 As shown, the existing lighting module includes a light source 01 and an inner lens 02, and the focus F01 of the inner lens 02 is located on the light source 01, so that the light emitted by the light source 01 projects a desired light shape after passing through the inner lens 02. Figure 3 and Figure 4 It can be seen that in the lighting module provided in the embodiment of the present application, the optical part of each lighting unit includes an inner lens 20 and an outer lens 30, and the focus F1 of the inner lens 20 is set to be located on the side of the light source 10 away from the inner lens 20, so that the inner lens 20 can converge more light emitted by the light source 10 to the outer lens 30, so that the outer lens 30 can project these light rays into sub-target light shapes, thereby improving the optical efficiency.

[0049] And, if Figure 3 As shown, in the lighting unit 100, the focus F2 of the outer lens 30 is located on the light source 10 or the light source 10 is close to the outer lens 30, so that different lighting units 100 can achieve different sub-target light shapes by adjusting the distance between the light incident surface of the inner lens 20 and the light incident surface of the outer lens 30. Specifically, for the lighting unit 100, the structure of the light source 10, the structure of the inner lens 20 and the structure of the outer lens 30 remain unchanged, and the relative position of the light source 10 and the inner lens 20 remains unchanged. Then, when the distance between the light incident surface of the inner lens 20 and the light incident surface of the outer lens 30 is different, the lighting unit 100 can achieve different sub-target light shapes.

[0050] For example, Figure 5a As shown, in the lighting unit 100, the focus F2 of the outer lens 30 is located on the light source 10. At this time, the distance between the light incident surface of the inner lens 10 and the light incident surface of the outer lens 30 is L. The sub-target light projected by the lighting unit 100 is as follows: Figure 5b As shown, it is approximately a rectangle.

[0051] Continue as Figure 6a As shown, the outer lens 30 is moved 1 mm toward the direction of the inner lens 20 away from the light source 10, so that the distance between the light incident surface of the inner lens 10 and the light incident surface of the outer lens 30 becomes L+1 mm. At this time, the sub-target light projected by the lighting unit 100 is as follows: Figure 6b As shown, it is approximately an elliptical rectangle.

[0052] Continue as Figure 7a As shown, the outer lens 30 is moved 1 mm further in the direction of the inner lens 20 away from the light source 10, so that the distance between the light incident surface of the inner lens 10 and the light incident surface of the outer lens 30 becomes L+2 mm. At this time, the sub-target light projected by the lighting unit 100 is as follows: Figure 7b As shown, it is approximately circular.

[0053] It can be understood that in the lighting unit 100, the focus F2 of the outer lens 30 is set on the light source 10 or on the side of the light source 10 close to the outer lens 30, so that different lighting units 100 can achieve different sub-target light shapes by adjusting the distance between the light incident surface of the inner lens 20 and the light incident surface of the outer lens 30.

[0054] In addition, it can also be understood that, for the lighting unit 100, the structure of the light source 10, the structure of the inner lens 20 and the structure of the outer lens 30 are kept unchanged, and the relative positions of the light source 10 and the inner lens 20, as well as the relative positions of the inner lens 20 and the outer lens 30 are kept unchanged. Then, when the shape of the light-emitting surface of the light source 10 changes, the lighting unit 100 can also achieve different sub-target light shapes.

[0055] It should be noted that, in the lighting module provided in the embodiment of the present application, it is allowed to change the position and angle of the sub-target light shape projected by the lighting unit 100 by moving and rotating the lighting unit 100, and it is also allowed to change the position and angle of the sub-target light shape projected by the lighting unit 100 by rotating the light source 10 in the lighting unit 100.

[0056] For example, Figure 8a As shown, the light source 10 may be an LED chip 11 with a rectangular light emitting surface. As we know, the LED chip at least includes a first-type semiconductor layer, an active layer and a second-type semiconductor layer. The active layer is a light emitting layer, and the shape of the active layer represents the shape of the light emitting surface of the LED chip. By rotating the LED chip 11 with a rectangular light emitting surface, it becomes as shown in FIG. Figure 8b As shown, the position and angle of the sub-target light shape projected by the lighting unit 100 can be changed.

[0057] It should also be noted that, in the lighting module provided in the embodiment of the present application, it is also allowed to adjust the current of the light source 10 in the lighting unit 100 to change the brightness of the sub-target light shape projected by the lighting unit 100 .

[0058] Based on the above description, it can be understood that the sub-target light shapes projected by the respective lighting units 100 in the lighting module can be combined to form a target light shape.

[0059] It can be seen that in the embodiment of the present application, the lighting module is modularized so that the lighting module includes at least two lighting units 100. The structure of each lighting unit 100 is similar, and they all include a light source 10, an inner lens 20 and an outer lens 30 arranged in sequence. In this way, the shape of the light-emitting surface of the light source 10 in the lighting unit 100 and the distance between the light-entering surface of the inner lens 20 and the light-entering surface of the outer lens 30 can be designed so that each lighting unit 100 projects a corresponding sub-target light shape. Further, the sub-target light shapes projected by each lighting unit 100 in the lighting module are combined to form a target light shape, which can be applied to high beams, low beams, high and low beams, and various signal lights, so that different lighting modules can use common components (such as the inner lens 20 and the outer lens 30), reduce the cost of the overall lighting system of the vehicle, reduce the inventory types of different lighting modules, and be environmentally friendly.

[0060] Optionally, in some embodiments of the present application, reference Figure 3 As shown, in the lighting unit 100, the focus F2 of the outer lens 30 is located on the light source 10 or between the light source 10 and the light incident surface of the inner lens 20, so that by adjusting the distance between the light incident surface of the inner lens 20 and the light incident surface of the outer lens 30, the lighting unit 100 can achieve different sub-target light shapes while ensuring the brightness of the sub-target light shape projected by the lighting unit 100.

[0061] Optionally, in some embodiments of the present application, in the lighting module, the structure of the inner lens 20 of each lighting unit 100 is the same, and the structure of the outer lens 30 of each lighting unit 100 is the same. In this way, different lighting units 100 can use common components, which is more conducive to the use of common components between different lighting modules, and more convenient for the modularization of the vehicle's overall lighting system, which can further reduce the inventory types of lighting modules and save costs.

[0062] like Figure 1 and Figure 2 As shown, in each lighting unit 100 of the lighting module, the inner lens 20 can be a rotationally symmetrical structure, and the outer lens can also be a rotationally symmetrical structure.

[0063] In other embodiments of the present application, in the lighting module, the structures of the inner lenses 20 of at least two lighting units 100 may be different, and / or the structures of the outer lenses 30 of at least two lighting units 100 may be different. For example, the light incident surfaces and / or light exit surfaces of the outer lenses 30 of at least two lighting units 100 may be different, so as to achieve different sub-target light shapes.

[0064] Since the present application aims to modularize the lighting module (including at least two lighting units) so that different lighting modules can use optical components, the structures of the inner lenses 20 of different lighting units 100 in one lighting module can be different, and similarly, the structures of the outer lenses 30 of different lighting units 100 can also be different. Of course, if the structures of the inner lenses 20 of each lighting unit 100 in the lighting module are the same, and the structures of the outer lenses 30 of each lighting unit 100 are also the same, then not only can the optical components be shared between different lighting modules, but also between different lighting units 100, which can further reduce the inventory types of lighting modules, facilitate the modular design of the overall lighting system of the vehicle, and save costs.

[0065] It can be understood that in the lighting unit 100, the structural design of the inner lens 20 and the outer lens 30 can achieve different shapes through cutting, such as square, circle, ellipse, triangle, etc., on the basis of ensuring the formation of sub-target light shape.

[0066] On the basis that the structures of the inner lenses 20 of the respective lighting units 100 in the lighting module are the same and the structures of the outer lenses 30 of the respective lighting units 100 are also the same, optionally, in some embodiments of the present application, in the lighting module, the relative positions of the light sources 10 and the inner lenses 20 in different lighting units 100 are the same, and the relative positions of the inner lenses 20 and the outer lenses 30 in different lighting units 100 are the same, that is, the lighting module is composed of two or more completely identical lighting units 100.

[0067] For example, including two Figure 5a The schematic diagram of the simulated light shape formed by the lighting module of the lighting unit 100 is shown in FIG. Fig. 9 shown.

[0068] For example, including five Figure 6a The schematic diagram of the simulated light shape formed by the lighting module of the lighting unit 100 is shown in FIG. Fig.10 shown.

[0069] For example, including seven Figure 7a The schematic diagram of the simulated light shape formed by the lighting module of the lighting unit 100 is shown in FIG. Fig.11 shown.

[0070] On the basis that the structures of the inner lenses 20 of each lighting unit 100 in the lighting module are the same and the structures of the outer lenses 30 of each lighting unit 100 are also the same, optionally, in other embodiments of the present application, in the lighting module, the relative positions of the light sources 10 and the inner lenses 20 in different lighting units 100 are the same, and the distances between the light incident surfaces of the inner lenses 20 and the light incident surfaces of the outer lenses 30 in at least two lighting units 100 are different.

[0071] For example, a lighting module includes two Figure 5a The lighting unit 100 shown, five Figure 6a The lighting unit 100 and seven Figure 7a As shown in the lighting unit 100, the sub-target light shapes formed by the respective lighting units 100 can be combined to form a complete low beam light shape, such as Fig.12 As shown, Fig.12 The low beam pattern shown is composed of Fig. 9 The light shape shown, Fig.10 The light shape shown and Fig.11 The light shapes shown are superimposed.

[0072] In addition, the lighting module including multiple lighting units 100 can also form a high beam light shape. The high beam light shape formed is as follows: Fig.13 shown.

[0073] Based on any of the above embodiments, optionally, in some embodiments of the present application, in at least one lighting unit 100 of the lighting module, Fig.14 and Fig.15 As shown, the light source 10 includes at least two LED chips 11, and the light-emitting surface of the LED chip 11 is rectangular. The at least two LED chips 11 are arranged so that the shape of the overall light-emitting surface formed by the combination of the light-emitting surfaces of the at least two LED chips 11 is the same as the shape of the sub-target light shape of the lighting unit. In this way, the inner lens 20 and the outer lens 30 in the lighting unit 100 only need to scale the light shape formed by the light source 10 to form the sub-target light shape, so that the structural design of the inner lens 20 and the outer lens 30 is simpler.

[0074] Further optionally, in some embodiments of the present application, such as Fig.14 As shown, in the lighting unit 100 whose light source 10 includes at least two LED chips 11, the at least two LED chips 11 include at least three LED chips 11, and the at least three LED chips 11 are arranged into two rows of LED chips 11, wherein the first row of LED chips 11 and the second row of LED chips 11 form a step.

[0075] For example, Fig.14As shown, in the lighting unit 100 whose light source 10 includes at least two LED chips 11, the at least two LED chips 11 include five LED chips 11, and the five LED chips are arranged into two rows of LED chips 11, wherein the first row of LED chips 11 includes two LED chips 11, and the second row of LED chips 11 includes three LED chips 11, and the first row of LED chips 11 and the second row of LED chips 11 form a vertical step to facilitate forming the characteristic of a 90° vertical cutoff line in the low beam light shape.

[0076] Further another optional, in some embodiments of the present application, such as Fig.15 As shown, in the lighting unit 100, the light source 10 includes at least two LED chips 11, the at least two LED chips 11 include a first LED chip 11A and a second LED chip 11B, and the second LED chip 11B forms a slope relative to the first LED chip 11A. Since the light-emitting surface of the LED chip 11 is rectangular, if the second LED chip 11B is to form a slope relative to the first LED chip 11A, the second LED chip 11B can be rotated by a certain angle relative to the first LED chip 11A, so that one corner of the rectangular light-emitting surface of the second LED chip 11B is protruding, thereby forming a slope.

[0077] For example, Fig.15 As shown, in the lighting unit 100, the light source 10 includes at least two LED chips 11, wherein the at least two LED chips 11 include two first LED chips 11A and one second LED chip 11B, and the one second LED chip 11B is rotated by a certain angle relative to the two first LED chips 11A to form a slope, so as to form the characteristics of inclined cutoff lines such as 15° and 45° in the low beam light shape.

[0078] Specifically, in some embodiments of the present application, in a lighting unit 100 of the lighting module, the light source 10 is Fig.15 The structure shown in FIG. 1 is a structure in which the inner lens 20 and the outer lens 30 are formed by Figure 6a The arrangement shown in FIG. 1 shows a sub-target light shape formed by the lighting unit 100. Fig.16 As shown; the lighting module also includes two Figure 6a The lighting unit 100 shown in FIG. Figure 6a The light source 10 in the lighting unit 100 shown is a single LED chip. Figure 6a The simulated light shape of the lighting unit 100 is shown as Fig.10 As shown; so, Fig.16 Simulated light shape overlay shown Fig.10 The simulated light shape shown can be obtained as Fig.17 Low beam pattern shown.

[0079] It should be noted that, when the light source 10 in the lighting unit 100 includes at least two LED chips 11 , the light emitting brightness of each LED chip 11 can be independently controlled to meet different lighting requirements.

[0080] Based on the same inventive concept, an embodiment of the present application further provides a vehicle lighting system, which includes a first lighting module and a second lighting module. The first lighting module and the second lighting module are both lighting modules provided by any of the above embodiments.

[0081] That is to say, in the vehicle lighting system provided in the embodiment of the present application, the first lighting module includes at least two lighting units, each lighting unit includes a light source, an inner lens and an outer lens arranged in sequence, the focus of the inner lens is located on the side of the light source away from the inner lens, the focus of the outer lens is located on the light source or on the side of the light source close to the outer lens, the light emitted by the light source is converged by the inner lens, incident on the outer lens, and then projected into a sub-target light shape through the outer lens; the second lighting module also includes at least two lighting units, each lighting unit includes a light source, an inner lens and an outer lens arranged in sequence, the focus of the inner lens is located on the side of the light source away from the inner lens, the focus of the outer lens is located on the light source or on the side of the light source close to the outer lens, the light emitted by the light source is converged by the inner lens, incident on the outer lens, and then projected into a sub-target light shape through the outer lens.

[0082] Furthermore, in the vehicle lighting system provided by the embodiment of the present application, the structure of the inner lens of at least some of the lighting units in the first lighting module is the same as the structure of the inner lens of at least some of the lighting units in the second lighting module;

[0083] And / or, the structure of the outer lenses of at least some of the lighting units in the first lighting module is the same as the structure of the inner lenses of at least some of the lighting units in the second lighting module.

[0084] For example, the first lighting module is a high beam lighting module, which is used to form a high beam light shape; the second lighting module is a signal light lighting module, which is used to form a signal light light shape; the first lighting module and the second lighting module can use the same light source and inner lens, but the distance between the light incident surface of the outer lens and the light incident surface of the inner lens and the current of the light source are different.

[0085] It can be seen that in the vehicle lighting system provided in the embodiment of the present application, since different lighting modules can use common components (such as inner lenses and outer lenses), the cost of the overall vehicle lighting system can be reduced, the inventory types of different lighting modules can be reduced, and it is environmentally friendly.

[0086] The various parts in this manual are described in a combination of parallel and progressive ways. Each part focuses on the differences from other parts, and the same or similar parts between the various parts can be referenced to each other.
