Description

Technical Field

[0001] The present invention relates to vehicle lamps, and more particularly to a vehicle high beam lamp module. In addition, the present invention also relates to a vehicle headlamp and a vehicle. Background Art

[0002] Driving safety has increasingly attracted people's attention. There are not a few driving accidents caused by improper use of high beam lamps every year. For example, when driving at night, when meeting an oncoming vehicle or there is a vehicle ahead, in order to prevent glare, the high beam lamp usually needs to be switched to a low beam lamp, or when overtaking a vehicle ahead, in order not to cause trouble to the vehicle ahead, the high beam lamp is switched to a low beam lamp. However, doing so has the contradiction that when overtaking, one clearly needs to see as far as possible but cannot use the high beam lamp, which has a certain degree of danger.

[0003] In the prior art, a vehicle high beam lamp module with an anti-glare function can solve the above problems. The so-called vehicle high beam lamp module with an anti-glare function can form a dark area in the area where the oncoming vehicle or the vehicle ahead is located, while having no impact on other lighting areas. It can avoid interfering with other vehicles while fully illuminating the road ahead of its own vehicle, improving the safety of night driving. For example, the utility model patent with the application date of September 14, 2017 and the publication number of CN207527498U discloses a vehicle optical module, which includes multiple groups of collimating lens units and a secondary lens. Each group of the collimating lens units is arranged in a matrix row at intervals, and there is a distance equal to the width of an outgoing light surface between the outgoing light surfaces of two adjacent collimating lenses without connection; there is a material connection at the interval on the incident light side to connect the dispersed and spaced collimating lenses into one body. By using two such vehicle optical modules in cooperation, a light pattern with multiple continuous light spots can be formed. Another example is the utility model patent with the application date of April 13, 2018 and the publication number of CN207962511U, which discloses an optical module including a condenser and multiple high beam light sources. The condenser includes multiple light guiding members, and the incident light ends of the light guiding members are respectively arranged corresponding to the high beam light sources one by one. The outgoing light ends of the light guiding members converge together and form an arc-shaped outgoing light part. By controlling different high beam light sources, the irradiation area of the light emitted by the vehicle lamp is controlled, so as to avoid the light directly irradiating the oncoming vehicle, thereby solving the problem of glare generated by the driver in the oncoming vehicle due to the high beam lamp irradiation.

[0004] The above vehicle high beam lamp modules can all form a high beam light pattern with multiple pixels and realize the high beam anti-glare function by controlling the lighting and extinguishing of the light sources, but they still have the following deficiencies:

[0005] 1. As the automotive industry develops and becomes more mature and stable, the types of headlight modules are becoming increasingly diverse. In terms of the comprehensive performance of headlight modules, customers have put forward more and more requirements, and the requirements for the size of headlight modules are also getting higher and higher. However, the light-emitting surface of the condenser in the existing technology is relatively large, resulting in a correspondingly large size of the lens, and the vertical opening size of the light-emitting port for emitting light at the front of the headlight is very large, which cannot meet the customer's requirements for the appearance of the headlight;

[0006] 2. Generally speaking, vehicles or pedestrians in front of a vehicle are located directly in front of the lane. It is necessary to control the corresponding light source to turn off to form a dark area according to the area where the vehicle or pedestrian is located. The higher the light pattern resolution in this area, that is, the more pixels the light pattern in this area contains and the narrower the pixel width, the easier it is to control the width of the dark area to match the width of the area where the vehicle or pedestrian is located; while for the areas on both sides in front of the lane where there are fewer vehicles or pedestrians, the light pattern resolution in this area does not need to be very high. Therefore, an ideal multi-pixel high beam light pattern should be a light pattern with a wide pixel width on both sides and a narrow pixel width in the middle. However, for the high beam light pattern with multiple pixels formed by the vehicle high beam light module in the existing technology, due to the unique structure of the condenser, the pixel widths of multiple pixels are basically the same, so when the vehicle is driving on the road, the light pattern resolutions in the area directly in front of the lane and on both sides in front of the lane are very high, that is, the pixel widths are all very narrow, and it is impossible to achieve a high beam light pattern with a wide pixel width on both sides and a narrow pixel width in the middle. Moreover, the number of light sources is very large, resulting in a high cost of the module. Summary of the Invention

[0065] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", etc. are all based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. Figure 16 The following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0066] As shown in

[0067] Such as Figures 1 to 27As shown in the figure, the present invention provides a vehicle high beam module, which includes a plurality of light-emitting light sources 6 and a lens group. The lens group is arranged in the light-emitting direction of the light-emitting light sources 6 and includes at least two levels of lenses. The first-level lens 1 in the lens group includes a plurality of condensing units 11 arranged side by side and having a set width of the light-incident surface. The light-incident surfaces of the condensing units 11 correspond to the light-emitting light sources 6 one by one. The light emitted by each light-emitting light source 6 can sequentially pass through the first-level lens 1 and other lenses in the lens group to form a plurality of light pattern forming units. The plurality of light pattern forming units are sequentially arranged to form a high beam light pattern with a plurality of pixels, and the width of each light pattern forming unit corresponds to the set width of the light-incident surface corresponding to it. Among them, the set width of each light-incident surface is set such that the width of the plurality of pixels decreases from the outer region of the light pattern to the central region of the light pattern.

[0068] By providing a lens group including at least two levels of lenses, the present invention can form a plurality of light pattern forming units. After the plurality of light pattern forming units are sequentially arranged, a high beam light pattern with continuous light pattern can be formed. At the same time, by using the converging effect of the multi-level lenses, as much light as possible emitted by the light-emitting light sources 6 can be collected, which can improve the light utilization rate, and the upper and lower dimensions of the last-level lens can be made smaller, thereby reducing the upper and lower dimensions of the entire vehicle headlight module and realizing the small-aperture design of the vehicle headlight. Among them, the lens group preferably includes a first-level lens 1, a second-level lens 2, and a third-level lens 3 arranged sequentially along the light-emitting direction of the light-emitting light sources 6. The first-level lens 1 includes a plurality of condensing units 11. Each condensing unit 11 can converge the light emitted by the light-emitting light sources 6 in the up-down, left-right directions. Each condensing unit 11 is preferably a plano-convex lens, that is, the light-incident surface of each condensing unit 11 is a plane, and its light-emitting surface is a curved surface protruding forward. The condensing units 11 are connected as a whole. The second-level lens 2 can converge the light emitted by each condensing unit 11 in the up-down direction, so that more light can be incident on the third-level lens 3, enabling the upper and lower dimensions of the third-level lens 3 to be made smaller. The second-level lens 2 is preferably a plano-convex cylindrical lens extending in the left-right direction. The longitudinal section of the light-incident surface of the second-level lens 2 is a straight line, and its longitudinal section is the section of the light-incident surface intercepted by a vertical plane extending in the front-back direction. The longitudinal section of the light-emitting surface is a curved line protruding forward, and its longitudinal section is the section of the light-emitting surface intercepted by a vertical plane extending in the front-back direction, so as to realize the convergence of the light emitted by each condensing unit 11 in the second-level lens 2 in the up-down direction, so that more light can be incident on the third-level lens 3. Of course, the second-level lens 2 can also be a bi-convex cylindrical lens; the third-level lens 3 can be an ordinary lens, such as a plano-convex lens or a bi-convex lens.

[0069] The primary lens 1 of the present invention includes a plurality of condensing units 11 arranged side by side and having light incident surfaces with a set width, which can enable the light emitted by each light-emitting light source 6 to form a plurality of light pattern forming units after passing through the primary lens 1 and other lenses in the lens group in sequence. The width of each light pattern forming unit corresponds to the set width of the corresponding light incident surface, so that a high beam light pattern with a plurality of pixels having specific widths can be formed, and the set width of each light incident surface can be set such that the widths of the plurality of pixels decrease from the outer region of the light pattern to the central region of the light pattern, thereby realizing a high beam light pattern with a narrow pixel width (high resolution) in the region near the vehicle's due front and a wide pixel width (low resolution) in the two side regions in front of the vehicle.

[0070] It should be noted that the high beam light pattern is formed by arranging a plurality of light pattern forming units in sequence in the left-right direction. If the light pattern forming units are exactly connected to each other, the width of the pixel is the same as the width of the corresponding light pattern forming unit. However, in this case, there will be an obvious bright-dark boundary line between the pixels, resulting in poor uniformity of the high beam light pattern. Therefore, in order to make the connection and transition between the pixels uniform, there is partial overlap between the light pattern forming units. At this time, the width of the light pattern forming unit should be greater than the width of the corresponding pixel. And the width of each light pattern forming unit corresponds to the set width of the corresponding light incident surface. Therefore, in order to achieve a light pattern with a narrow pixel width in the region near the vehicle's due front and a wide pixel width in the two side regions in front of the vehicle, light pattern forming units with different widths can be obtained by setting the set width of each light incident surface, so as to form a high beam light pattern with a plurality of pixels having specific widths.

[0071] Figure 7 and Figure 9 are respectively a light pattern simulation diagram of the above vehicle high beam lamp module applied to the left and right vehicle lamps. Figure 8 and Figure 10 are respectively a light pattern line diagram of the above vehicle high beam lamp module applied to the left and right vehicle lamps. Refer to Figure 7 and Figure 9 shown. The two light patterns are superimposed to form the entire high beam light pattern of the vehicle. The regions where the light rays projected onto the light distribution screen in the two side regions in front of the vehicle are the outer regions of the light patterns in the light pattern diagrams shown in Figure 7 and Figure 9 . The left region in Figure 7 and the right region in Figure 9 are the outer regions of the light patterns. The regions where the light rays projected onto the light distribution screen in the region near the vehicle's due front are the central regions of the light patterns in the light pattern diagrams shown in Figure 7 and Figure 9 . The right region in Figure 7 and the left region in Figure 9 are the central regions of the light patterns. Among them, the scales in the figures represent the widths of the respective pixels, which are characterized by the angles of the light rays.​​​​Figure 7 The width of each pixel in Figure 7 decreases from left (the outer region of the light pattern) to right (the central region of the light pattern). Correspondingly, when the headlight module of the present invention is applied to the left headlight, the set width of the light incident surface of each light condensing unit 11 is set from right to left to be in one-to-one correspondence with Figure 11 the width of each pixel in. That is, the set width of the light incident surface of multiple light condensing units 11 decreases from right to left. Specifically, as shown in Figure 9 Since each light condensing unit 11 in the left region is close to the optical axis 30 of the three-stage lens, the area where the light emitted by each light condensing unit 11 in the left region is projected on the light distribution screen is located in the central region of the light pattern. Therefore, this left region is called the central region. Correspondingly, the right region is far from the optical axis 30 of the three-stage lens, and the area where the light emitted by each light condensing unit 11 in the right region is projected on the light distribution screen is located in the outer region of the light pattern. Therefore, this right region is called the outer region. However, for the uniform connection between pixels and the partial superposition between each light pattern component unit, the set width of the light incident surface of multiple light condensing units 11 can be set according to the width of the light pattern component unit to be obtained, and there is not necessarily a trend of increasing or decreasing in size. As long as the final arrangement of each light pattern component unit can obtain a light pattern with the pixel width decreasing from the outer region of the light pattern to the central region of the light pattern. When the headlight module of the present invention is applied to the right headlight, the set width of the light incident surface of each light condensing unit 11 is set from left to right to be in one-to-one correspondence with Figure 12As shown, each light condensing unit 11 in the right region is close to the optical axis 30 of the three-stage lens. Similarly, this right region is called the central region, and the left region is far from the optical axis 30 of the three-stage lens, and this left region is called the outer region. However, for the uniform connection between pixels, partial superposition is made between the light shape forming units. The set width of the incident light surface of multiple light condensing units 11 can be set according to the width of the light shape forming unit required, and there is not necessarily a trend of increasing or decreasing in size. As long as the light shape with the pixel width decreasing from the outer region of the light shape to the central region of the light shape can be obtained after the final arrangement of each light shape forming unit. Thus, when the vehicle high beam lamp module of the present invention is applied to the left headlamp and the right headlamp, the set width of the incident light surface of multiple light condensing units 11 is set to be the width of the incident light surface of the light condensing unit 11 in the outer region, and the width of the incident light surface of the light condensing unit 11 in the central region is narrow. The set width of the incident light surface of multiple light condensing units 11 decreases from the outer region to the central region, so that the high beam light emitted from the left and right headlamps can form a high beam light shape with a narrow pixel width in the region near the front of the vehicle and a wide pixel width in the two side regions in front of the vehicle after superposition. In addition, in order to make the focal points of each light condensing unit 11 on the same straight line, the front and rear lengths of multiple light condensing units 11 are set to be long for the light condensing unit 11 in the outer region and short for the light condensing unit 11 in the central region. The front and rear lengths of multiple light condensing units 11 decrease from the outer region to the central region, that is, as Figure 11 shown, the front and rear lengths of multiple light condensing units 11 decrease from right to left, and as Figure 12 shown, the front and rear lengths of multiple light condensing units 11 decrease from left to right.

[0072] Preferably, in order to prevent the wrong installation when the vehicle high beam lamp module of the present invention is installed on the left and right headlamps, the headlamp module of the present invention can adopt a structure that can be used for both the left and right lamps, that is, the structure of the primary lens 1 applied to the left headlamp and the right headlamp is the same. The set width of the incident light surface of multiple light condensing units 11 is set to be the width of the incident light surface of the light condensing unit 11 in the outer region, and the width of the incident light surface of the light condensing unit 11 in the central region is narrow. The set width of the incident light surface of multiple light condensing units 11 decreases from the outer region to the central region, specifically as Figure 13As shown, the left and right side regions of the multiple light condensing units 11 are outer regions, and the middle region thereof is the central region. The set width of the light incident surface of the multiple light condensing units 11 decreases from the left and right side regions to the middle region, so that the far-light emission light patterns of the left and right vehicle lamps can also form a far-light pattern with a narrow pixel width in the region near the front of the vehicle and a wide pixel width in the two side regions in front of the vehicle after being superimposed. There are two implementation methods for the far-light emission light pattern of this structural form. One is that the light-emitting light sources 6 corresponding to the right outer region and the central region of the multiple light condensing units 11 in the left vehicle lamp are turned on, and the left vehicle lamp projects a light pattern with a narrow pixel width in the central region of the light pattern and a wide pixel width in the outer region (the left region of the light pattern); the light-emitting light sources 6 corresponding to the left outer region and the central region of the multiple light condensing units 11 in the right vehicle lamp are turned on, and the right vehicle lamp projects a light pattern with a narrow pixel width in the central region of the light pattern and a wide pixel width in the outer region (the right region of the light pattern). After the two are superimposed, a complete far-light pattern is formed. And because the light-emitting light sources 6 corresponding to the central regions of the multiple light condensing units 11 in the left and right vehicle lamps are both turned on, there is an overlap in the central region of the far-light pattern formed after the left and right vehicle lamps are superimposed, so that the central brightness of the far-light pattern is higher; the other is that the light-emitting light sources 6 of the vehicle far-light lamp modules in the left and right vehicle lamps are all turned on, and both the left and right vehicle lamps project light patterns with a narrow pixel width in the central region and a wide pixel width in the two side regions. After the two are superimposed, a complete far-light pattern can also be formed. Similarly, in order to make the focal points of the light condensing units 11 on the same straight line, the front and rear lengths of the multiple light condensing units 11 are set to be longer for the light condensing units 11 in the outer regions (the left and right side regions) and shorter for the light condensing units 11 in the central region (the middle region). The front and rear lengths of the multiple light condensing units 11 decrease from the outer regions to the central region.

[0073] As Figures 1 to 6As shown, since the front-to-back length dimensions of the respective light condensing units 11 are different, in order to be adapted to the respective light condensing units 11, the secondary lens 2 has a certain degree of curvature in the left-right direction, that is, the longitudinal section line of the light incident surface of the secondary lens 2 is a straight line or a curve protruding backward, and the longitudinal section line of the light exiting surface is a curve protruding forward, so as to achieve the convergence of the light emitted by the respective light condensing units 11 in the up-down direction, so that more light can be incident on the tertiary lens 3. Moreover, the outer portion of the secondary lens 2 corresponding to the respective light condensing units 11 located in the outer region bends forward, so that the light incident surface of the secondary lens 2 is as close as possible to the light exiting surface of the respective light condensing units 11, so that more of the emitted light of the respective light condensing units 11 is incident on the secondary lens 2, so as to improve the light utilization rate of the emitted light of the respective light condensing units 11; at the same time, it is also necessary to consider that the curvature of the secondary lens 2 is as close as possible to the curvature of the focal plane of the tertiary lens 3, so as to be able to form a clear light pattern. It should be noted that the focal plane is theoretically a plane, but due to the influence of optical aberrations, especially field curvature aberration, the focal plane of the tertiary lens 3 actually has a concave spherical curvature. Therefore, if the light exiting surface of the secondary lens 2 is set on this curved focal plane, the imaging is the clearest. Of course, the secondary lens 2 may also not have a curvature, and its light pattern effect can also meet the requirements. In addition, preferably, the width of the secondary lens 2 in the left-right direction is greater than the width of the primary lens 1 in the left-right direction, and both its left and right sides bend forward, so that the secondary lens 2 can be applied to both the left headlight and the right headlight, reducing the mold cost and improving the versatility of the parts.

[0074] Preferably, each of the light emitting light sources 6 is an LED light source, and each of the light emitting light sources 6 is provided at the focal point of the respective light condensing unit 11 corresponding thereto.

[0075] In order to further improve the light utilization rate of the vehicle high beam lamp module of the present invention, preferably, the light emitting light source 6 located on the right side of the optical axis 30 of the tertiary lens is provided on the right side of the optical axis of the respective light condensing unit 11 corresponding thereto, and the light emitting light source 6 located on the left side of the optical axis 30 of the tertiary lens is provided on the left side of the optical axis of the respective light condensing unit 11 corresponding thereto, specifically as Figure 15 shown, so that compared with the case where the optical axis of the light emitting light source 6 as Figure 14 shown coincides with the optical axis of the respective light condensing unit 11 corresponding thereto, more of the light emitted by the light emitting light source 6 after passing through the light condensing unit 11 is incident on the tertiary lens 3. Therefore, the light utilization rate can be further improved.

[0076] Since the high beam module of the vehicle is a headlight module independent of the low beam module of the vehicle, which is different from the headlight module with integrated high and low beams. When the headlight is in the low beam illumination module mode, when looking at the vehicle from the front, the low beam module of the vehicle emits light, while the high beam module of the vehicle does not emit light. Therefore, in order to achieve the appearance effect that the high beam module of the vehicle also emits light in the low beam illumination mode, on the basis of the above embodiments, the high beam module of the vehicle can be additionally provided with a low beam auxiliary lighting unit. The low beam auxiliary lighting unit does not participate in low beam illumination, and its function is only to make the tertiary lens 3 appear lit when looking at the headlight from the front of the vehicle. The low beam auxiliary lighting unit can be arranged above or below or on the left or right side of the secondary lens 2, and is preferably arranged above the secondary lens 2 so that the emitted light after passing through the tertiary lens 3 can be projected into the light pattern area of the low beam light pattern without affecting low beam illumination, specifically as Figures 16 to 27 shown.

[0077] Specifically, the low beam auxiliary lighting unit includes a primary optical element 4 and an auxiliary lighting light source corresponding to the primary optical element 4 (not shown in the figure). The light emitted by the auxiliary lighting light source is incident on the tertiary lens 3 after passing through the primary optical element 4, so that the tertiary lens 3 can be lit.

[0078] Among them, the primary optical element 4 has a converging effect on the light emitted by the auxiliary lighting light source, and it can have various structures. As a specific structure, as Figures 16 to 21 shown, the primary optical element 4 has a primary light incident surface 41 and a primary light exit surface 42. A light channel is formed in the front-rear direction between the primary light incident surface 41 and the primary light exit surface 42. A condenser cup structure 43 is provided on the primary light incident surface 41, and the outer contour surface of the condenser cup structure 43 is a curved surface with a gradually increasing diameter from the rear to the front. More specifically, the primary light incident surface 41 is a plane, the primary light exit surface 42 is a curved surface protruding forward, and the vertical height of the primary light incident surface 41 is greater than the vertical height of the primary light exit surface 42 so that more light enters the primary light incident surface 41, and the horizontal width of the primary light incident surface 41 is less than the horizontal width of the primary light exit surface 42 to save materials and reduce production costs. By providing the condenser cup structure 43 on the primary light incident surface 41 of the primary optical element 4, the converging effect on light is better, and thus the light utilization rate is also higher.

[0079] As another specific structure, as Figure 24 and Figure 25As shown, the primary optical element 4 has a primary light incident surface 41 and a primary light exit surface 42. A light channel is formed in the front-back direction between the primary light incident surface 41 and the primary light exit surface 42. The primary light incident surface 41 is a plane, and the primary light exit surface 42 is a curved surface protruding forward. Moreover, the vertical height of the primary light incident surface 41 is less than the vertical height of the primary light exit surface 42, and the left-right width of the primary light incident surface 41 is less than the left-right width of the primary light exit surface 42. This primary optical element 4 has a simple structure, can save materials, reduce production costs, and has a high light utilization rate.

[0080] As another specific structure, as Figure 22 and Figure 23 shown, the primary optical element 4 has a primary light incident surface 41 and a primary light exit surface 42. A light channel is formed in the front-back direction between the primary light incident surface 41 and the primary light exit surface 42. The primary light incident surface 41 is a plane, and the primary light exit surface 42 is a curved surface protruding forward. Moreover, the vertical height of the primary light incident surface 41 is equal to the vertical height of the primary light exit surface 42, and the left-right width of the primary light incident surface 41 is equal to the left-right width of the primary light exit surface 42. This primary optical element 4 has a simpler structure and is easier to process.

[0081] Since the front-back dimensions of the primary optical element with the above various structures are quite different from the front-back dimensions of the secondary lens, it is not convenient for the positioning and installation of the primary optical element. Therefore, two or more primary optical elements 4 can be arranged side by side in the left-right direction and connected as a whole, so that the front-back dimension of the primary optical element 4 can be reduced. At this time, these two or more primary optical elements 4 and the secondary lens 2 can be formed as a whole, which can simplify the structure of the vehicle headlight module, make the structure more compact, and facilitate the positioning and installation of the primary optical element 4. Figure 26 and Figure 27 Shown is that two primary optical elements 4 connected as a whole and the secondary lens 2 are formed as a whole.

[0082] Preferably, as Figures 16 to 19 shown, an auxiliary cylindrical lens 5 is provided in front of the primary optical element 4. The auxiliary cylindrical lens 5 is preferably a plano-convex cylindrical lens extending in the left-right direction. Since the vertical dimension of the tertiary lens 3 is small, by providing the auxiliary cylindrical lens 5 in front of the primary optical element 4, the outgoing light of the primary optical element 4 can be converged in the vertical direction, enabling more light to enter the tertiary lens 3, thereby improving the light utilization rate of this low-beam auxiliary lighting unit. Of course, the auxiliary cylindrical lens 5 can also be a biconvex cylindrical lens.

[0083] The second aspect of the present invention also provides a vehicle headlight, including the above vehicle high-beam light module.

[0084] By setting the vehicle high beam module, it is possible to achieve a small opening design for the light outlet of the vehicle headlamp and a high beam light pattern with a narrow pixel width in the area near the vehicle's due front and wide pixel widths in the two side areas in front of the vehicle.

[0085] The third aspect of the present invention further provides a vehicle, including the above-mentioned vehicle headlamp.

[0086] By setting the vehicle headlamp, it is possible to achieve a high beam light pattern with a narrow pixel width in the area near the vehicle's due front and wide pixel widths in the two side areas in front of the vehicle.

[0087] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0088] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any appropriate manner. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0089] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
