Description

Technical Field

[0001] The present invention relates to a vehicle lamp, in particular to a primary optical element. In addition, the present invention also relates to a high-beam lighting device, a vehicle lamp and a vehicle. Background Art

[0002] Driving safety has received increasing attention from people. Every year, there are many accidents caused by improper use of high beams. For example, when driving at night, when meeting or ahead of a vehicle, you usually need to switch from high beams to low beams to avoid glare, or when overtaking a vehicle in front, you switch to low beams to avoid causing trouble to the vehicle in front. However, this has a contradiction that you need to see as far as possible when overtaking, but you cannot use high beams, which is dangerous.

[0003] The anti-glare high beam solves the above problem. The anti-glare high beam can form a dark area in the area where the other vehicle or the vehicle in front is located, while other lighting areas are not affected. It can fully illuminate the road in front of the vehicle while avoiding interference with other vehicles, thereby improving the safety of night driving. The existing anti-glare high beam structure can refer to Chinese patent CN207762807U, which discloses that by designing different surface shapes in different areas on the circumference of the shading roller, the light shape can be changed accordingly when the roller rotates to different positions, so that the high beam can generate a special cutting shape, and the cut-off part of the high beam forms a dark area, which will not cause glare when it is aimed at other vehicles. Through the rotary actuator installed on the light-emitting module in the lamp, the on-board camera recognizes the change in the moving position of the vehicle in front of the car, and the feedback signal drives the rotary actuator to rotate the light-emitting modules in the left and right lights of the car respectively, so that the dark area moves with the position of the vehicle in front of the car.

[0004] The above technical solution has the following shortcomings. First, the anti-glare high beam lamp needs to be equipped with a shading roller and a driving structure for driving the shading roller to rotate separately, and the system structure is very complicated. Second, the headlight module with a reflective unit as the primary optical element mostly uses an LED light source, and its luminous flux per unit area is only 300-400lm / mm 2 , resulting in a large light-emitting area, and then a larger reflective surface of the reflective unit, and a larger size of the lens matched with the reflective unit, which makes the volume of the entire headlight module very large; finally, the headlight module of the prior art first positions and installs the primary optical element and the radiator, the lens bracket with the lens installed, and the radiator separately, and then positions and installs the whole module, which causes multiple assembly errors between the primary optical element and the lens, and the manufacturing accuracy and positioning and installation accuracy are difficult to guarantee, resulting in low accuracy of the optical system. Summary of the invention

[0005] The first problem to be solved by the present invention is to provide a primary optical element with a simple structure. When applied to the left and right headlights, the primary optical element can form a high beam light shape with a dark area to prevent glare.

[0006] In addition, the problem that the present invention also solves is to provide a high-beam lighting device that can prevent glare, has a small size, reduces positioning and installation errors, and has a high optical system accuracy.

[0007] Furthermore, the problem to be solved by the present invention is to provide a vehicle lamp which can prevent glare, has a high precision optical system, and has strong applicability.

[0008] Furthermore, the problem to be solved by the present invention is to provide a vehicle which can prevent glare and has a high precision optical system.

[0009] In order to solve the above technical problems, the present invention provides a primary optical element, which is applied to a left headlight and a right headlight, and comprises a reflecting unit and a shading structure arranged on or integrally formed on the reflecting unit, wherein the shading structure can shield part of the reflected light of the reflecting unit, wherein the primary optical element is one of the following two structures:

[0010] In the case where the primary optical element is used for the left vehicle lamp, the light shielding structure is arranged at the left part in front of the reflective unit, and the light shielded and the light not shielded are bounded by the right side edge and the upper side edge thereof;

[0011] When the primary optical element is used for the right headlight, the shading structure is arranged at the right side portion in front of the reflecting unit, and the light blocked and the light not blocked are bounded by the left side edge and the upper side edge thereof.

[0012] Preferably, when the primary optical element is used for the left headlight, the right edge and the upper edge of the shading structure are perpendicular to each other; when the primary optical element is used for the right headlight, the left edge and the upper edge of the shading structure are perpendicular to each other.

[0013] More preferably, the shading structure is a rectangular shading plate.

[0014] Further preferably, a heat sink is provided on the reflection unit.

[0015] In a second aspect, the present invention provides a high-beam lighting device, comprising the primary optical element, circuit board and lens mentioned above, wherein the circuit board is provided with a corresponding light source, the circuit board and the lens are respectively connected to the primary optical element, and the light emitted by the light source is reflected to the lens by the reflection unit and projected by the lens to form the exit light shape of the left headlight or the exit light shape of the right headlight.

[0016] Preferably, a lens connecting portion is provided on or integrally formed with the lens, a primary optical element connecting portion is provided on or integrally formed with the primary optical element, and the lens connecting portion is connected to the primary optical element connecting portion.

[0021] In a fourth aspect, the present invention provides a vehicle, comprising the vehicle light described above.

[0022] It can be seen from the above technical solution of the present invention that the shading structure of the primary optical element of the present invention can block part of the reflected light of the reflection unit, so that when the primary optical element is applied to the left and right headlights, the left and right headlights respectively form a left headlight high beam light shape with a left light-dark cutoff line and a right headlight high beam light shape with a right light-dark cutoff line, and then the left headlight high beam light shape and the right headlight high beam light shape are superimposed to form a high beam light shape with a dark area. When the high beam of the headlight is used, if the other party or the front vehicle or pedestrian is encountered, this dark area is not illuminated by light, so as to prevent glare to the driver of the other party or the front vehicle or pedestrian. In addition, the high beam lighting device based on the above primary optical element of the present invention directly positions and installs the primary optical element and the lens, avoiding multiple assemblies among the light source, the primary optical element and the lens, so that the device is not only small in size, but also has high positioning accuracy of the parts, thereby improving the accuracy of the optical system. In the headlight based on the above-mentioned high beam lighting device in the present invention, a driving mechanism is used to enable the high beam lighting device to move left and right, so that the high beam lighting device of the left headlight cooperates with the high beam lighting device of the right headlight, and the width and position of the dark area can be adjusted by moving left and right respectively to meet the lighting needs of more driving environments and improve the applicability of the headlight.

[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] First of all, it should be noted that, unless otherwise clearly specified and limited, the terms "connection" and "installation" should be understood in a broad sense. For example, the 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, or it can be the internal connection of two components or the interaction relationship between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In the description of the present invention, it is necessary to explain that some directional words involved in the following description for the purpose of clearly explaining the technical solution of the present invention, such as "front" and "left and right", refer to the left and right directions of the vehicle in normal driving state. In addition, GB4599-2007 stipulates that the light distribution performance of the vehicle headlight should be measured on a light distribution screen 25m in front of the reference center of the headlight; the light-dark cutoff line refers to the dividing line where the light beam is projected onto the light distribution screen and the light and dark change is visually felt. Among them, the L-shaped light-dark cutoff line refers to the light-dark cutoff line in the shape of "L", and the reverse L-shaped light-dark cutoff line refers to the light-dark cutoff line in the shape of "L" and the shape of "L" is symmetrical.

[0048] A primary optical element provided by the first aspect of the present invention is Figures 1 to 3 , applied to left and right headlights, including a reflective unit 1 and a shading structure 2 arranged on or integrally formed on the reflective unit 1, the shading structure 2 can block part of the reflected light of the reflective unit 1, wherein the primary optical element is one of the following two structures:

[0049] In the case where the primary optical element is used for the left vehicle lamp, the light shielding structure 2 is arranged at the left part in front of the reflective unit 1, and the light shielded and the light not shielded are bounded by the right side edge 21 and the upper side edge 22 thereof;

[0050] When the primary optical element is used for the right vehicle lamp, the shading structure 2 is arranged at the right part in front of the reflecting unit 1 , and the light to be shielded and the light not to be shielded are bounded by the left edge 23 and the upper edge 22 .

[0051] It should be noted that the reflection unit 1 may be a reflector, or a component with a reflection surface, or a component with a light reflection function.

[0052] Through the primary optical element of the above basic technical scheme of the present invention, the shading structure 2 can block part of the reflected light of the reflecting unit 1, so that part of the reflected light cannot be projected to the front of the vehicle and a dark area is formed in front of the vehicle. Specifically, when the primary optical element is applied to the left headlight, the right side edge 21 and the upper side edge 22 of the shading structure 2 are used to make the blocked light and the unblocked light be separated by the right side edge 21 and the upper side edge 22, so that the left headlight forms a left headlight high beam light shape 9 with a left light and dark cut-off line; when the primary optical element is applied to the right headlight, the left side edge 23 and the upper side edge 22 of the shading structure 2 are used to make the blocked light and the unblocked light be separated by the left side edge 23 and the upper side edge 22, so that the right headlight forms a right headlight high beam light shape 10 with a right light and dark cut-off line.

[0053] Further, the high beam light shape 9 of the left headlight and the high beam light shape 10 of the right headlight can form a high beam light shape after being superimposed. The high beam light shape can be a conventional full high beam light shape or a high beam center area light shape located in the center area of ​​the full high beam light shape. For example, the primary optical element of the present invention is applied to form the high beam center area light shape. Accordingly, the headlight also needs to be equipped with an auxiliary lighting device to form a high beam widening area light shape that can match the high beam center area light shape. The two are superimposed to form a full high beam light shape. Auxiliary lighting is a technical means well known to those skilled in the art. When there are vehicles or pedestrians in front of the vehicle or on the other side, the high beam light shape 9 of the left headlight and the high beam light shape 10 of the right headlight are moved left and right according to the position of the vehicle or pedestrian and the width of the area where they are located. The two are superimposed to form a high beam light shape with a dark area 11, and the dark area 11 is located between the left light-dark cutoff line and the right light-dark cutoff line. The dark area 11 covers the area where the vehicle or pedestrian in front or on the other side is located, which can effectively prevent the high beam from interfering with the driver or pedestrian of the vehicle in front or on the other side and prevent glare. When there are no vehicles or pedestrians in front of or on the other side of the vehicle, the left headlight high beam pattern 9 and the right headlight high beam pattern 10 are moved left and right to increase the overlapping part of the two so that there is no dark area 11 after the two are superimposed, which can provide sufficient high beam lighting for the driver of the vehicle.

[0054] As a preferred embodiment of the present invention, when the primary optical element is used for the left headlight, the right side edge 21 and the upper side edge 22 of the shading structure 2 are perpendicular to each other; when the primary optical element is used for the right headlight, the left side edge 23 and the upper side edge 22 of the shading structure 2 are perpendicular to each other. The right side edge 21 and the upper side edge 22 can form an L-shaped left light-dark cutoff line on the corresponding outgoing light shape of the high-beam lighting device of the left headlight; the left side edge 23 and the upper side edge 22 can form an inverted L-shaped right light-dark cutoff line on the corresponding outgoing light shape of the high-beam lighting device of the right headlight. The above-mentioned shading structure forms an L-shaped left light-dark cutoff line or an inverted L-shaped right light-dark cutoff line, which is a preferred shape of the light-dark cutoff line in the present invention. It should be noted that the left light-dark cutoff line may not be strictly L-shaped, and the right light-dark cutoff line may not be strictly inverted L-shaped, as long as a left-right symmetrical or approximately symmetrical light-shielding dark area shape can be formed between the left light-dark cutoff line and the right light-dark cutoff line, see Figures 4 to 6 The left light-dark cutoff line and the right light-dark cutoff line can be bilaterally symmetrical or approximately symmetrical inner angle shapes, outer angle shapes, or L-shaped shapes with rounded corners, and the shading structure 2 is designed to have corresponding edge shapes.

[0055] More preferably, see Figures 1 to 3 , the shading structure 2 is a rectangular shading plate. At this time, the right edge 21 and the upper edge 22 of the rectangular shading plate can form a left cutoff portion suitable for the left headlight to form an L-shaped left light-dark cutoff line; the left edge 23 and the upper edge 22 of the rectangular shading plate can form a right cutoff portion suitable for the right headlight to form an inverted L-shaped right light-dark cutoff line.

[0056] Further preferably, a heat sink 3 is provided on the reflective unit 1, which is beneficial to the heat dissipation inside the primary optical element, avoiding excessively high local temperature of the primary optical element, and ensuring that the output light shape of the primary optical element is stable and accurate.

[0057] Based on the primary optical element of the present invention, the second aspect of the present invention provides a high beam lighting device, see Figures 7 and 8 , including the above-mentioned primary optical element, circuit board 5 and lens 6, the circuit board 5 is provided with a corresponding light source 4, the circuit board 5 and the lens 6 are respectively connected to the primary optical element, the light emitted by the light source 4 is reflected to the lens 6 by the reflection unit 1 and projected by the lens 6 to form the outgoing light shape of the left headlight or the outgoing light shape of the right headlight.

[0058] When the high-beam lighting device is applied to the left headlight, under the action of the primary optical element, the reflected light of the reflecting unit 1 is projected through the lens 6 so that the high-beam light shape of the left headlight has a left light-dark cut-off line; when the high-beam lighting device is applied to the right headlight, under the action of the primary optical element, the reflected light of the reflecting unit 1 is projected through the lens 6 so that the high-beam light shape of the right headlight has a right light-dark cut-off line, and the high-beam light shape 9 of the left headlight and the high-beam light shape 10 of the right headlight can be superimposed to form a high-beam light shape with a dark area 11, and the dark area 11 is located between the left light-dark cut-off line and the right light-dark cut-off line.

[0059] Based on the above-mentioned high-beam lighting device, the primary optical element and the lens 6 are directly positioned and installed, reducing the use of auxiliary parts such as lens brackets or transition brackets, avoiding multiple assemblies of various parts, and ensuring high positioning accuracy among the light source 4, the primary optical element and the lens 6, thereby improving the accuracy of the optical system and reducing the volume of the high-beam lighting device.

[0060] Preferably, the lens 6 is provided with or integrally formed with a lens connecting portion 61, the primary optical element is provided with or integrally formed with a primary optical element connecting portion 7, and the lens connecting portion 61 is connected to the primary optical element connecting portion 7. The provision of the primary optical element connecting portion 7 and the lens connecting portion 61 makes the installation of the primary optical element and the lens 6 more stable and the positioning more accurate.

[0061] More preferably, a heat sink 8 is provided on the side of the circuit board 5 away from the light source 4. The heat sink 8 helps to dissipate the heat generated by the light source 4 in time, avoids local overtemperature from interfering with the power supply 4 and the circuit board 5, and maintains the stability of the light source 4.

[0062] Further preferably, the lens 6 is provided with a light shield 62 on the side surface connected with the light emitting surface thereof. Here, the light shield 62 can be connected to the lens 6 by threaded connection, riveting, gluing or welding, and the light shield 62 can effectively prevent the outgoing light of the primary optical element from being emitted from the side surface of the lens 6, and only the light emitting surface of the lens 6 is exposed to the outside.

[0063] In the present invention, the light source 4 can be a laser light source, an LED light source or other lighting light source for vehicle lights. Preferably, the light source 4 is a laser light source. The luminous flux per unit area of ​​the laser light source is 1200 lm / mm 2A single laser light source can achieve the light shape and brightness required by the regulations, and the luminous area is very small. Therefore, the size of the corresponding primary optical element reflective unit 1 is reduced, and its focal length can be 10-20mm, preferably 10mm. Correspondingly, the size of the lens 6 can also be reduced to 5-15mm in height and 20-40mm in width, wherein the height of the lens 6 is preferably 10mm and the width is preferably 30mm. In order to allow as much light reflected by the reflective unit 1 as possible to enter the lens 6, the focal length of the lens 6 is also reduced to 10-30mm. Therefore, the length of the entire high beam lighting device in the front-to-back direction, the width in the left-to-right direction, and the height in the up-and-down direction can be significantly reduced, and can be specifically designed to be 60-90mm long, 22-42mm wide, and 20-50mm high, preferably 80mm long, 32mm wide, and 40mm high. At this time, the volume of the high beam lighting device is greatly reduced, and it can be designed as a miniature vehicle light module.

[0064] The third aspect of the present invention provides a headlight, comprising the above-mentioned high-beam lighting device and a driving mechanism for driving the high-beam lighting device to move left and right. The high-beam lighting device of the left headlight forms a left headlight high-beam light shape 9 with a left light-dark cutoff line, and the high-beam lighting device of the right headlight forms a right headlight high-beam light shape 10 with a right light-dark cutoff line. The high-beam light shape 9 of the left headlight and the high-beam light shape 10 of the right headlight can form a high-beam light shape with a dark area 11 after being superimposed on each other. The dark area 11 is located between the left light-dark cutoff line and the right light-dark cutoff line. The high-beam light shape 9 of the left headlight and the high-beam light shape 10 of the right headlight are respectively moved left and right by the driving mechanism, and cooperate with each other to adjust the width and position of the dark area 11 to adapt to the different positions and different widths of the areas where the vehicles or pedestrians in front or on the other side are located, and can meet the lighting needs of more driving environments.

[0065] It should be noted that the present invention does not specifically limit the driving mechanism. Preferably, the driving mechanism adopts an AFS rotating mechanism (Adaptive Front-Lighting System rotating mechanism, i.e., an adaptive automobile headlight system rotating mechanism). The specific structure of the AFS rotating mechanism can refer to patent CN207049828U. Of course, the driving mechanism of the present invention can also use AFS rotating mechanisms of other structural forms.

[0066] In a preferred specific embodiment of the present invention, the headlight comprises a left headlight and a right headlight, the high beam lighting device of the left headlight comprises a left circuit board, a primary optical element and a left lens, one side of the left circuit board is provided with a corresponding left light source, and the other side is provided with a radiator 8, the left lens is provided with a shading cover 62 on the side connected with its light emitting surface, wherein the shading structure 2 of the primary optical element is a rectangular shading plate, and is located on the left side in front of the reflecting unit 1, at this time, the right side edge 21 and the upper side edge 22 of the rectangular shading plate make the high beam light shape of the left headlight have a left bright and dark cut-off line, and the left headlight is also provided with a device for driving the corresponding high beam lighting device to move left and right The left driving mechanism for driving the right headlight comprises a right circuit board, a primary optical element and a right lens, one side of the right circuit board is provided with a corresponding right light source, and the other side is provided with a radiator 8, wherein the shading structure 2 of the primary optical element is a rectangular shading plate, and is located on the right side in front of the reflecting unit 1, at this time, the left edge 23 and the upper edge 22 of the rectangular shading plate make the high beam light shape of the right headlight have a right bright and dark cut-off line, and the right headlight is also provided with a right driving mechanism for driving the corresponding high beam lighting device to move left and right; the left light source and the right light source both adopt laser light sources, and the left driving mechanism and the right driving mechanism both adopt AFS rotating mechanism.

[0067] When the left light source and the right light source are turned on, the light path diagram of the left light source is shown in FIG. Fig. 9 The light from the left light source is reflected by the reflection unit 1, shielded by the shading structure 2, and then emitted to the left lens and projected by the left lens to form a left vehicle lamp high beam light shape 9 with an L-shaped light-dark cut-off line. The left vehicle lamp high beam light shape 9 refers to Fig.10 Accordingly, after the light from the right light source is reflected by the reflection unit 1, it is shielded by the shading structure 2 and then emitted to the right lens and projected by the right lens to form a right vehicle lamp high beam light pattern 10 with an inverted L-shaped light and dark cut-off line. The right vehicle lamp high beam light pattern 10 is shown in Fig.11 The left headlight high beam light pattern 9 and the right headlight high beam light pattern 10 are superimposed to form a high beam light pattern with a dark area 11. Fig.12 According to the driving situation, the position of the high beam lighting device in the left headlight can be adjusted by the left driving mechanism, and the position of the high beam lighting device in the right headlight can be adjusted by the right driving mechanism to adjust the position and width of the dark area 11 to form a suitable dark area 11 to prevent glare to the drivers of the vehicles ahead or oncoming vehicles or pedestrians.

[0068] It can be seen from the above description that the shading structure 2 of the primary optical element of the present invention can block part of the reflected light of the reflection unit 1, so that when the primary optical element is applied to the left and right headlights, the left and right headlights respectively form a left headlight high beam light shape 9 with a left light-dark cutoff line and a right headlight high beam light shape 10 with a right light-dark cutoff line, and then the left headlight high beam light shape 9 and the right headlight high beam light shape 10 are superimposed to form a high beam light shape with a dark area 11, and the shading structure 2 is integrally formed on the primary optical element, and the structure is simple. When the high beam of the headlight is used, if the other party or the front vehicle or pedestrian is encountered, this dark area 11 is not illuminated by light, so as to prevent the other party or the front vehicle driver or pedestrian from being dazzled. In addition, the high beam lighting device based on the above primary optical element of the present invention directly positions and installs the primary optical element and the lens 6, avoiding multiple assemblies between the light source 4, the primary optical element and the lens 6. The device is not only small in size, but also has high positioning accuracy of the parts, thereby improving the accuracy of the optical system. In the headlight based on the above-mentioned high beam lighting device in the present invention, a driving mechanism is used to enable the high beam lighting device to move left and right, so that the high beam lighting device of the left headlight cooperates with the high beam lighting device of the right headlight, and the width and position of the dark area 11 can be adjusted by moving left and right respectively to meet the lighting needs of more driving environments and improve the applicability of the headlight.

Therefore, at least all the beneficial effects brought by the technical solutions of the above-mentioned primary optical element, high-beam lighting device and headlight embodiments are achieved.
