Description

Technical Field

[0001] The present invention relates to a vehicle lamp, and in particular to a vehicle lamp module. In addition, the present invention also relates to a vehicle lamp and a vehicle. Background Art

[0002] Pixelated headlights refer to headlights whose headlight shape is divided into multiple pixelated light shapes. The complete light shape is formed by stitching together multiple pixelated light shapes. The pixelated light shape is composed of several pixels and has high resolution. If the light source of a certain pixel in the pixelated light shape is turned off, the pixel is a dark area. If the light source of a certain pixel is turned on, the pixel is a bright area. For pixelated low-beam headlights, the low-beam light-dark cutoff line is also stitched together by several pixels. The formation principle can be found in patent document EP3502550A1. At present, common pixelated headlights are generally realized through technologies such as DLP (Digital Light Processing), DMD (Digital Micromirror Device) or Micro LED. Publication No. CN110345441A discloses a pixelated headlight.

[0003] The low beam zone III light shape is a part of the low beam light shape of the car headlight, which is located above the low beam cut-off line and is mainly used to illuminate road signs and other signs. Since the illuminance value of the low beam zone III light shape above the low beam cut-off line is much lower than the illuminance value of the low beam main area light shape below the cut-off line, and the illuminance value of the low beam zone III light shape cannot exceed 0.7lx, it is difficult for the above-mentioned pixelated low beam headlights to achieve a low beam zone III light shape that meets regulatory requirements. Even if the light source above the low beam cut-off line is reduced to the lowest power, the illuminance value of the low beam zone III light shape obtained is much greater than 0.7lx, which cannot meet regulatory requirements. In addition, the projection optical element of a general pixelated headlight is a lens, such as Figure 1 As shown, the main low beam light shape 100 formed therein has a small amount of virtual light 102 above the low beam light cut-off line 101. Although it is located above the low beam light cut-off line 101, its illuminance value is low and cannot meet the illuminance value requirements of the low beam zone III light shape at test points such as P1+P2+P3, P4+P5+P6, etc. For example, these test points require that P1+P2+P3 is greater than 0.3lx and P4+P5+P6 is greater than 0.6lx.

[0004] In view of the above-mentioned problems of the prior art, it is necessary to design a new type of headlight module to form a low beam zone III light shape that can be used with pixelated low beam headlights and meet regulatory requirements. Summary of the Invention

[0006] The second technical problem to be solved by the present invention is to provide a headlight with a better coordination effect between the main low beam light shape, the auxiliary low beam light shape and the low beam zone III light shape.

[0007] The third technical problem to be solved by the present invention is to provide a vehicle in which the coordination between the main low beam light pattern, the auxiliary low beam light pattern and the low beam zone III light pattern is better and the lighting effect is better.

[0008] In order to achieve the above-mentioned objectives, the present invention provides, on one hand, a headlight module, which is configured to be able to project an auxiliary low beam light shape and a low beam zone III light shape on a light distribution screen, and the auxiliary low beam light shape and the low beam zone III light shape can be superimposed on the main low beam light shape to form an overall low beam light shape; wherein, the upper boundary angle of the low beam zone III light shape is greater than +4°, the lower boundary angle is +1°~+2°, the left boundary angle is less than -8°, and the right boundary angle is greater than +8°.

[0012] Preferably, the headlight optical element is provided with a light input portion, a transmission portion and a light output portion in sequence from back to front along the light output direction, the light input portion is arranged corresponding to the light source, and a light output curved surface convex forward is formed on the end of the light output portion away from the transmission portion, and a light-dark cutoff portion is provided at the connection between the bottom surface of the transmission portion and the light output portion.

[0013] Further preferably, the rear end and the front end of the lens along the light emitting direction are respectively the light incident surface and the light emitting surface of the lens, and the zone III forming structure is located on the light emitting surface of the lens.

[0014] Specifically, the light-emitting surface of the lens is a curved surface convex forward, the structure forming zone III is set to a groove structure and / or a convex structure, and the side of the groove structure and the convex structure opposite to the light-entering surface of the lens is configured as the light-emitting surface of zone III, and the angle of the light-emitting surface of zone III relative to the horizontal direction is greater than the angle of the light-emitting surface of the lens relative to the horizontal direction.

[0015] Typically, the region III forming structure is located on the top of the light emitting surface of the lens.

The light deflection surface enables part of the light emitted from the zone III light transmission portion to the lens, and part of the light that can be emitted from the lens to the area below +1° above the HH axis, to be deflected on the light deflection surface.

[0018] Further preferably, the light deflecting surface is configured to extend obliquely forward from the top of the light emitting surface of zone III to the bottom surface of the transmission part, or to extend obliquely backward from the top of the light emitting surface of zone III to the bottom surface of the transmission part.

[0051] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connection" and "contact" should be understood in a broad sense. For example, connection can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two elements or an interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0053] It should be understood that the directional relationships indicated by "top", "bottom", "front", "rear", "left" and "right" are only for the convenience of describing the present invention and simplifying the description. Based on the headlight module, "front" refers to the direction indicated by the light emitting direction, "rear" refers to the direction opposite to "front", "left" refers to the left side along the light emitting direction, and "right" refers to the right side along the light emitting direction, that is, the same as the left and right side directions of the vehicle when it is driving normally. "Top" refers to the upper side along the light emitting direction, and "bottom" refers to the lower side along the light emitting direction. The terms are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0054] In the present invention, light shape refers to the projection shape of the light beam of the headlight module on the vertical plane light distribution screen 25m away from the front of the vehicle. The HH axis is the horizontal axis of the center of the light distribution screen, and the VV axis is the vertical axis of the center of the light distribution screen. The angle of the light shape boundary refers to the light irradiation range of the light beam in the upper, lower, left and right directions in front of the headlight. The angle of the light shape boundary located above the HH axis is positive, the angle of the light shape boundary located below the HH axis is negative, the angle of the light shape boundary located to the right of the VV axis is positive, and the angle of the light shape boundary located to the left of the VV axis is negative.

[0055] A first aspect of the present invention provides a headlight module that is configured to project an auxiliary low beam light shape 200 and a low beam zone III light shape 300 on a light distribution screen. The auxiliary low beam light shape 200 and the low beam zone III light shape 300 can be superimposed on the main low beam light shape 100 to form an overall low beam light shape; wherein the upper boundary angle of the low beam zone III light shape 300 is greater than +4°, the lower boundary angle is +1° to +2°, the left boundary angle is less than -8°, and the right boundary angle is greater than +8°.

[0056] It should be noted that the upper boundary angle of the auxiliary low beam light pattern 200 in the present invention is -0.57 degrees, and the main low beam light pattern 100 can be formed by a lighting module in the prior art and has a low beam light-dark cut-off line 101. Preferably, the main low beam light pattern 100 is a pixelated light pattern formed by projecting a pixelated low beam module. In this case, the main low beam light pattern 100 formed is shown in FIG. Figure 1 As shown, there will be a small amount of virtual light 102 above the low beam cut-off line 101. Since there is a test point B50L below +1° in the low beam light pattern area, the test point B50L corresponds to the position of the eyes of the oncoming vehicle driver 50m away from the headlamp. Its coordinates on the light distribution screen are (-3.4°, +0.6°), where -3.4° is the coordinate value of the HH axis and +0.6° is the coordinate value of the VV axis. The illuminance value of B50L is required to be less than 0.4lx. The illuminance value requirement of B50L can be met by using the illuminance of the virtual light 102. If the lower boundary angle of the low beam III zone light pattern 300 is covered to below +1°, there will be a risk of B50L being too bright, causing dazzle to the driver of the other vehicle.

[0057] The vehicle lamp module of the present invention can project the following image on the light distribution screen: Figure 2 The auxiliary low beam light shape 200 and the low beam zone III light shape 300 are shown, wherein the upper, lower, left and right boundaries of the low beam zone III light shape 300 formed by the headlight module relative to the HV axis can better match the angles of the pixelated low beam module formed as shown in FIG. Figure 1 The auxiliary low beam light shape 200 formed by the headlight module can be used in conjunction with the low beam zone III light shape 300 and the main low beam light shape 100 to illuminate the left and right widening of the low beam light shape, so that the low beam light shape formed is as follows: Figure 3 The overall low beam light shape shown has a wider illumination range and better lighting performance.

[0058] As a preferred embodiment of the low beam III light pattern 300, the upper boundary angle of the low beam III light pattern 300 is greater than or equal to +5°, the left boundary angle is less than or equal to -15°, and the right boundary angle is greater than or equal to +15°. In this case, the upper boundary angle of the low beam III light pattern 300 allows the low beam III light pattern 300 to have a higher illumination height, while the left and right boundary angles allow the low beam III light pattern 300 to have a wider illumination width.

[0059] As a preferred embodiment of the present invention, see Figure 4 、 Figure 6 and Figure 10As shown, the headlight module includes a headlight optical element 1, a light source arranged corresponding to the headlight optical element 1, a lens 2 located on the light output path of the headlight optical element 1, and a zone III forming structure 3 for forming a low beam zone III light shape 300; wherein, the zone III forming structure 3 is arranged on the headlight optical element 1 or on the lens 2, and the light emitted by the light source is projected to the lens 2 through the headlight optical element 1, and then projected through the lens 2 to form an auxiliary low beam light shape 200 and a low beam zone III light shape 300. When the III-zone forming structure 3 is positioned on the headlight optical element 1, light emitted by the light source is transmitted through the headlight optical element 1. Part of the light is projected by the headlight optical element 1 onto the lens 2, where it is then projected by the lens 2 to form the auxiliary low-beam light pattern 200. Part of the light is projected by the III-zone forming structure 3 onto the lens 2, where it is then projected by the lens 2 to form the low-beam III-zone light pattern 300. When the III-zone forming structure 3 is positioned on the lens 2, light emitted by the light source is transmitted through the headlight optical element 1 onto the lens 2, where it is projected by the lens 2 to form the auxiliary low-beam light pattern 200, while the III-zone forming structure 3 simultaneously projects the low-beam III-zone light pattern 300. This simple structural design of the headlight module improves the connection between the auxiliary low-beam light pattern 200 and the low-beam III-zone light pattern 300.

[0060] As a specific embodiment of the headlight optical element 1 of the present invention, the headlight optical element 1 is provided with a light input portion 11, a transmission portion 12 and a light output portion 13 in sequence from back to front along the light output direction. The light input portion 11 is arranged corresponding to the light source, and a light output curved surface convex forward is formed at the end of the light output portion 13 away from the transmission portion 12. A light-dark cutoff portion 14 is provided at the connection between the bottom surface of the transmission portion 12 and the light output portion 13. The structure of the light input portion 11 can be set to a light input curved surface protruding backward, or a focusing structure, such as a focusing cup, so as to better converge the light emitted by the light source to the transmission portion 12, and transmit it to the light output portion 13 through the transmission portion 12; a light output curved surface protruding forward is formed on the light output portion 13, so that its output light converges toward the middle, so that the size of the lens 2 can be made smaller; the light-dark cut-off portion 14 is used to form the upper boundary of the auxiliary low beam light shape 200, so that the auxiliary low beam light shape 200 can better cooperate with the low beam zone III light shape 300; there is light reflection on the bottom surface of the transmission portion 12, which can improve the light transmission efficiency of the headlight optical element 1.

[0061] As a specific structure of the above preferred embodiment, see Figure 5 、 Figure 7 and Figure 8 As shown, the rear end and the front end of the lens 2 along the light emitting direction are respectively the lens light incident surface 21 and the lens light emitting surface 22, and the III zone forming structure 3 is located on the lens light emitting surface 22. At this time, the light path for forming the low beam III zone light shape 300 is shown in FIG. Figure 9As shown, the light emitted by the light source enters the transmission part 12 through the light incident part 11 and is transmitted to the light emitting part 13, and is projected onto the light incident surface 21 of the lens through the light emitting part 13, and then is projected through the zone III forming structure 3 to form the low beam zone III light shape 300.

[0062] In order to form a better auxiliary low beam light shape 200 and low beam zone III light shape 300, see Figure 4 、 Figures 6 to 8 As shown, preferably, the lens light exit surface 22 is a forward-convex curved surface, and the zone III forming structure 3 is configured as a groove structure and / or a protrusion structure. The surface of the groove structure and the protrusion structure opposite the lens light incident surface 21 is configured as the zone III light exit surface 31. The angle of the zone III light exit surface 31 relative to the horizontal direction is greater than the angle of the lens light exit surface 22 relative to the horizontal direction. The zone III light exit surface 31 is configured to be more inclined to the vertical direction, so that the light emitted by the zone III forming structure 3 can be deflected to the position of the low beam zone III light pattern 300 within the overall low beam light pattern, forming the boundary angle of the low beam zone III light pattern 300.

[0063] The Zone III-forming structure 3 can be positioned at the top, middle, or bottom of the lens light-exiting surface 22, preferably at the top or bottom. The specific location of the Zone III-forming structure 3 is designed based on the overall low-beam light pattern to better project the light forming the Zone III light pattern 300 to the appropriate location within the overall low-beam light pattern. Furthermore, the Zone III-forming structure 3 is preferably located at the top of the lens light-exiting surface 22. When the lamp module is applied to a headlight, the headlight bezel obscures the Zone III-forming structure 3 when viewing the headlight from the front side, thereby not affecting the headlight's aesthetics. Alternatively, the Zone III-forming structure 3 can be positioned on the lens light-entering surface 21 as needed.

[0064] As another specific structure of the above preferred embodiment, see Figure 10 As shown, the region III forming structure 3 is located on the bottom surface of the transmission portion 12 .

[0065] Specifically, see Figure 11 、 Figure 12 、 Figure 15 and Figure 16As shown, the zone III forming structure 3 includes a zone III light transmission portion 32 integrally formed on the bottom surface of the transmission portion 12 and a zone III light emitting surface 31 located on the front end surface of the zone III light transmission portion 32. A light deflection surface 33 is provided between the top of the zone III light emitting surface 31 and the bottom surface of the transmission portion 12. The light deflection surface 33 allows part of the light emitted from the zone III light transmission portion 32 to the lens 2, which can be emitted from the lens 2 to the area below +1° above the HH axis, to be deflected on the light deflection surface 33. Specifically, the zone III forming structure 3 can be set so that the angle of the zone III light emitting surface 31 relative to the horizontal direction is greater than the angle of the light deflection surface 33 relative to the horizontal direction. At this time, the light path of the low beam zone III light shape 300 is shown in FIG. Figure 13 and Figure 14 As shown, light emitted by the light source enters the transmission portion 12 through the light entrance portion 11. Part of the light enters the zone III light transmission portion 32 through the bottom surface of the transmission portion 12. It is then transmitted through the zone III light transmission portion 32 to the zone III light exit surface 31 and projected onto the lens 2. This is then projected through the lens 2 to form the low-beam zone III light pattern 300. The light deflecting surface 33 deflects the light that impinges on the light deflecting surface 33, preventing light that would otherwise impinge on the area below +1° above the HH axis of the overall low-beam light pattern from impinging on the area below +1° above the HH axis, thereby forming a lower boundary angle of +1° to +2° for the zone III light pattern 300.

[0066] More preferably, see Figure 12 and Figure 16 As shown, the light deflecting surface 33 is configured to extend obliquely backward from the top of the light emitting surface 31 of zone III to the bottom surface of the transmission portion 12, or to extend obliquely forward from the top of the light emitting surface 31 of zone III to the bottom surface of the transmission portion 12. The extension direction of the light deflecting surface 33 can be designed according to the manufacturing process.

[0067] To reduce the amount of light emitted from the light deflecting surface 33, the surface of the light deflecting surface 33 is provided with one of a matte pattern, an anti-reflection film, and a matte coating. The matte pattern can be a leather grain or a toothed structure with alternating concave and convex shapes provided on the surface of the light deflecting surface 33. The matte coating can be a matte black paint, or the surface can be provided with leather grain and then coated with ordinary black paint.

[0068] Based on the aforementioned vehicle light module of the present invention, a second aspect of the present invention provides a vehicle light comprising the aforementioned vehicle light module and a lighting module for forming a main low-beam light pattern 100. The lighting module for the main low-beam light pattern 100 is preferably a pixelated low-beam module. The auxiliary low-beam light pattern 200 and the low-beam zone III light pattern 300 formed by the vehicle light module of the present invention can form a good coordination effect with the main low-beam light pattern 100, thereby improving the low-beam lighting effect of the vehicle light.

[0069] A third aspect of the present invention provides a vehicle including the above-mentioned headlight, which at least has all the beneficial effects brought about by the technical solutions of the above-mentioned headlight module and headlight embodiment, and will not be described in detail here.

[0070] From the above description, it can be seen that the vehicle lamp module of the present invention can project the following Figure 2 The auxiliary low beam light shape 200 and the low beam zone III light shape 300 are shown, wherein the upper, lower, left and right boundaries of the low beam zone III light shape 300 formed by the headlight module relative to the HV axis can better match the angles of the pixelated low beam module formed as shown in FIG. Figure 1 The main low beam light shape 100 shown in the figure is matched, so that after the low beam III zone light shape 300 is superimposed on the main low beam light shape 100, the illuminance value of each test point of the low beam III zone light shape 300 meets the requirements of the regulations; at the same time, the auxiliary low beam optics 200 formed by the headlight module can be used in conjunction with the low beam III zone light shape 300 and the main low beam light shape 100 to illuminate and form the left and right widening of the low beam light shape, so that the formed Figure 3 The overall low beam light shape shown has a wider left and right illumination range and better left and right lighting performance.

[0071] In a preferred embodiment of the present invention, the headlight module of the present invention is provided with a light source, a headlight optical element 1, a lens 2 and a zone III forming structure 3. The zone III forming structure 3 is provided on the headlight optical element 1 or the lens 2, that is, the light emitted by the light source can be projected to the lens 2 via the headlight optical element 1, and then projected by the lens 2 to form an auxiliary low beam light shape 200 and a low beam zone III light shape 300. The structure is simple, and the connection effect between the auxiliary low beam light shape 200 and the low beam zone III light shape 300 is better; further, through the angle setting of the zone III light emitting surface 31 or the structural setting of the light deflection surface 33, the boundary angle of the low beam zone III light shape 300 is made more accurate and stable in the position in the overall low beam light shape.

[0072] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention may be subjected to various simple modifications, including combining the specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
