Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile lighting technology, and in particular to a lighting module and a vehicle lamp. Background Art
[0002] In the current vehicle headlamp module system, only the low beam module is provided with a cutoff line structure, so the maximum luminous flux (Emax value) of the low beam light pattern is located at the lower left of the HV point. Since the high beam module does not have a cutoff line structure, when the high and low beams are turned on at the same time, the high and low beam light patterns are superimposed, resulting in the brightest point (maximum luminous flux) not being at the HV point, but on the left side of the HV point, which causes an "eccentric" phenomenon in the connection between the high and low beam light patterns. That is, when the light pattern is projected on the light distribution screen, it will be clearly felt that the brightest point deviates from the center line. This situation can easily cause the driver's perspective to be confused during actual driving, leading to accidents. Utility Model Content

Detailed implementation manners
[0031] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. The components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0032] 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 claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.
[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0034] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "coupled" 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 directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0035] In the current vehicle headlamp module system, only the low beam module is provided with a cutoff structure. Therefore, the maximum luminous flux (Emax value) of the low beam light type is located at the lower left of the HV point. Since the high beam module does not have a cutoff structure, when the high and low beams are turned on at the same time, the high and low beam light types are superimposed, resulting in the brightest point (maximum luminous flux) not being at the HV point, but on the left side of the HV point, which causes an "eccentric" phenomenon in the connection between the high and low beam light types. That is, when the light type is projected on the light distribution screen, it will be clearly felt that the brightest point deviates from the center line. This situation can easily cause the driver's perspective to be confused during actual driving, leading to accidents. It should be noted that the HV point refers to the intersection of the H axis and the V axis on the light distribution screen. The light distribution screen usually refers to a vertical plane set 25 meters in front of the vehicle.
[0036] In order to solve the above technical problems, the present application provides a lighting module and a vehicle lamp.

Figure 3 , Figure 4 As shown, the edge of the low beam reflection structure 102 has a low beam cut-off line structure 104; the low beam light is reflected on the low beam reflection curved surface 103, and after being emitted by the second lens 115, it is projected on the light distribution screen to form a low beam light pattern 105 with a low beam cut-off line 119.

The high beam reflection structure 106 has a high beam reflection curved surface 107, and the edge of the high beam reflection structure 106 has a high beam cut-off line structure 108. The high beam light is reflected on the high beam reflection curved surface 107, and after being emitted by the first lens 112, it is projected on the light distribution screen to form a high beam light pattern 110 with a high beam cut-off line 109. For details, please refer to Figure 8 shown.
[0039] Reference Figure 9 As shown, the low beam cut-off line 119 is connected with the high beam cut-off line 109, so that the high beam pattern 110 is superimposed on the low beam pattern 105. Figure 10 This is a light type in which the high beam cut-off line structure 108 is not provided.
[0040] An embodiment of the present application provides a lighting module, including a high beam module 100 and a low beam module 101 .
[0041] It should be noted that the high-beam module 100 and the low-beam module 101 can be integrally arranged, or can be formed by combining two independent modules to form a lighting module, and the above structural settings can be achieved. Therefore, no special limitation is made here, and those skilled in the art can select according to needs.
[0042] The low-beam module 101 of the embodiment of the present application includes a low-beam reflection structure 102, a low-beam reflection curved surface 103 is provided on the low-beam reflection structure 102, and a low-beam cut-off line structure 104 is provided at the edge of the low-beam reflection structure 102; the low-beam light is reflected on the low-beam reflection curved surface 103, and after being emitted through the second lens 115, a low-beam light pattern 105 with a low-beam cut-off line 119 is projected on the photometric screen.
[0043] It should be noted that there can be multiple low-beam reflection curved surfaces 103, that is, there are multiple low-beam reflection curved surfaces 103 arranged in sequence on the low-beam reflection structure 102. The direction of sequential arrangement can be a straight line direction extending horizontally. The low-beam reflection curved surface 103 can be an ellipsoidal reflection surface or a parabolic reflection surface. The projection contour of the low-beam reflection curved surface 103 on the horizontal plane is close to a U shape, and the low-beam cut-off line structure 104 is specifically provided at the root where the low-beam reflection curved surface 103 is connected to the body of the low-beam reflection structure 102, that is, the bottom of the U shape.
[0044] The high-beam module 100 of the embodiment of the present application includes a high-beam reflection structure 106, a high-beam reflection curved surface 107 is provided on the high-beam reflection structure 106, and a high-beam cut-off line structure 108 is provided at the edge of the high-beam reflection structure 106; the high-beam light is reflected on the high-beam reflection curved surface 107, and after being emitted through the first lens 112, a high-beam light pattern 110 with a high-beam cut-off line 109 is projected on the photometric screen.
[0045] Similarly, it should be noted that there can be multiple high-beam reflection curved surfaces 107, that is, there are multiple high-beam reflection curved surfaces 107 arranged in sequence on the high-beam reflection structure 106. The direction of sequential arrangement can be a straight line direction extending horizontally. The high-beam reflection curved surface 107 can be an ellipsoidal reflection surface or a parabolic reflection surface. The projection contour of the high-beam reflection curved surface 107 on the horizontal plane is close to a U shape, and the high-beam cut-off line structure 108 is specifically provided at the root of the high-beam reflection curved surface 107, that is, the bottom of the U shape.
[0046] It should be noted that the high-beam cut-off line structure 108 is not provided at the edge of each high-beam reflection curved surface 107. Exemplarily, there are five high-beam reflection curved surfaces 107 arranged in sequence, and the high-beam cut-off line structure 108 is formed on two or three of the high-beam reflection curved surfaces 107. The high-beam reflection curved surface 107 without the high-beam cut-off line structure 108 can be used to form the broadening of the high-beam light pattern 110.
[0047] In the embodiment of the present application, the low beam cut-off line 119 and the high beam cut-off line 109 can be connected in the horizontal direction. The high beam light pattern and the low beam light pattern 105 are respectively located above and below the cut-off line after connection, realizing superposition. Through the high beam cut-off line structure 108 in the embodiment of the present application, the high beam light pattern 110 can be restricted, so that the maximum value of the luminous flux (Emax value) after the superposition of the high beam light pattern 110 and the low beam light pattern 105 is located at the HV point, preventing the "eccentric" phenomenon from occurring at the connection of the high and low beam light patterns 105.
[0048] In the embodiment of the present application, the high beam cut-off line structure 108 is arranged on the high beam reflection structure 106 of the high beam module 100, so that the projected high beam light pattern 110 has a high beam cut-off line 109. Therefore, in the embodiment of the present application, the maximum value of the luminous flux (Emax value) can be located at the HV point after the superposition of the high beam light pattern 110 and the low beam light pattern 105. Compared with the prior art, the brightest point of the embodiment of the present application will not deviate from the center line, and can provide a better lighting effect for night driving.
[0049] Referring to Figure 1 As shown, as an optional implementation manner, the high beam module further includes a high beam circuit board 111, and a first light source located at the focal position of the high beam reflection curved surface 107 is arranged on the high beam circuit board 111; the light generated by the first light source is reflected by the high beam reflection curved surface 107 and then emitted by the first lens 112 to project and form a high beam light pattern 110.
[0050] It should be noted that there can be multiple first light sources. The high beam module 100 in the embodiment of the present application further includes a high beam circuit board 111, and a plurality of first light sources are arranged at intervals on the high beam circuit board 111, and the plurality of first light sources are correspondingly arranged with a plurality of high beam reflection curved surfaces 107.
[0051] That is to say, the first light source is located at the focus of the corresponding high beam reflection curved surface 107, and emits high beam light rays towards the high beam reflection curved surface 107. The light is reflected on the high beam reflection curved surface 107 and then emitted by the first lens 112, and projects on the light distribution screen to form a high beam light pattern 110 with a high beam cut-off line 109.
[0052] Referring to Figure 2 、 Figure 3 As shown, as an optional implementation manner, the low beam module further includes a low beam circuit board 114, and a second light source located at the focal position of the low beam reflection curved surface 103 is arranged on the low beam circuit board 114; the light generated by the second light source is reflected by the low beam reflection curved surface 103 and then emitted by the second lens 115 to project and form a low beam light pattern 105.
[0053] It should be noted that there can be multiple second light sources. The low beam module 101 of the embodiment of the present application further includes a low beam circuit board 114, and a plurality of second light sources are arranged at intervals on the low beam circuit board 114, and the plurality of second light sources are correspondingly arranged with the plurality of low beam reflection surfaces 103.
[0054] That is to say, the second light source is located at the focus of the corresponding low beam reflection surface 103, and emits low beam light rays towards the low beam reflection surface 103. The light rays are reflected on the low beam reflection surface 103 and then emitted through the second lens 115, forming a low beam light pattern 105 with a low beam cut-off line 119 on the light distribution screen.
[0055] Refer to Figure 1 、 Figure 2 As shown, as an optional implementation manner, it further includes a radiator 117, and both the high beam circuit board 111 and the low beam circuit board 114 are attached to the radiator 117.
[0056] Furthermore, the embodiment of the present application further includes a radiator 117, and both the high beam circuit board 111 and the low beam circuit board 114 are attached to the radiator 117. It should be noted that a large amount of heat will be generated during the operation of the high beam circuit board 111 and the low beam circuit board 114. Therefore, through the arrangement of the radiator 117, the high beam circuit board 111 and the low beam circuit board 114 can be cooled, so that the heat does not accumulate on the circuit board, preventing the circuit board from being damaged and effectively improving the service life of the components on the circuit board.
[0057] As an optional implementation manner, the high beam circuit board 111 and the low beam circuit board 114 are respectively arranged on both sides of the radiator 117. Further, in the vertical direction of the lighting module, the projections of the low beam circuit board 114 and the high beam circuit board 111 overlap.
[0058] It should be noted that in the embodiment of the present application, the high beam circuit board 111 and the low beam circuit board 114 are installed on both sides of the radiator 117, so that the low beam reflection structure 102 and the high beam reflection structure 106 are respectively arranged on both sides. At this time, the low beam module 101 and the high beam module 100 are two separate modules, and can be arranged directly corresponding to each other in the vertical direction of the lighting module, that is, in the vertical direction of the lighting module, the projections of the low beam circuit board 114 and the high beam circuit board 111 overlap.
[0059] As an optional implementation manner, the first lens 112 and the second lens 115 are an integral part. Further, the light-emitting surfaces of the first lens 112 and the second lens 115 are formed as smooth planes or curved surfaces.
[0060] The first lens 112 and the second lens 115 of the embodiment of the present application are integrally formed. In addition, the light-emitting surfaces of the first lens 112 and the second lens 115 are formed into a smooth plane or curved surface to make the appearance of the lighting module better. At this time, the low-beam reflection structure 102 and the high-beam reflection structure 106 can be separately arranged.

At this time, the low-beam module 101 and the high-beam module 100 are arranged in the left-right direction of the lighting module. Further, the low-beam reflection structure 102 and the high-beam reflection structure 106 can be set into an integral structure. In addition, the first lens 112 and the second lens 115 can also be an integral part. The embodiment of the present application can set the high-beam module 100 and the low-beam module 101 into a single module. Compared with the above-mentioned independent setting method, the embodiment of the present application can greatly simplify the assembly process of the lighting module and facilitate disassembly and assembly.
[0062] Among them, the materials of the first lens 112 and the second lens 115 are transparent plastics. Exemplarily, the materials can be PMMA or PC.

[0064] Among them, the cross-section of the cylindrical surface 118 in the horizontal direction is a curve, and the cylindrical surface 118 is the curved surface formed by stretching the curve in the up-down direction.
[0065] It should be noted that the cylindrical surface 118 of the embodiment of the present application has a converging effect on light rays, realizing the horizontal single-direction collimation of light rays.
[0066] A vehicle lamp provided by an embodiment of the present application includes a lamp body and a lighting module arranged in the lamp body.
[0067] The vehicle lamp provided by the embodiment of the present application adopts the above-mentioned lighting module. The low-beam module 101 and the high-beam module 100 of the lighting module are both provided with cut-off line structures, so that the maximum value of the luminous flux (Emax value) after the high-beam light pattern 110 and the low-beam light rays are superimposed is located at the HV point, and the brightest point formed is on the center line, preventing accidents caused by the driver's visual angle confusion during actual driving and providing favorable lighting conditions for night driving.
