[0038] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0039] Reference below Figure 1-Figure 7 The vehicle lamp 100 according to the embodiment of the present invention is described, and the vehicle lamp 100 can be applied to a vehicle.
[0040] Combination Figure 1-Figure 7 As shown, the vehicle lamp 100 according to the present invention can mainly include: a low beam lamp group 10 and a low beam reflector 20. The low beam lamp group 10 includes a plurality of low beam lamp sources 11 arranged at intervals, and the low beam reflector 20 is formed with a plurality of reflecting surfaces 21, and the plurality of reflecting surfaces 21 correspond to the plurality of low beam lamp sources 11 one by one, and the edge of the reflecting surface 21 is provided with a bright and dark cut-off line structure 211 to form a bright and dark cut-off line of the low beam.
[0041] Specifically, the low beam lamp group 10 includes a plurality of low beam lamp sources 11 that are arranged at intervals, and a plurality of reflecting surfaces 21 are formed on the low beam reflector 20, so that the plurality of reflecting surfaces 21 correspond one-to-one to the plurality of low beam lamp sources 11. In this way, the light emitted by the plurality of low beam lamp sources 11 toward the low beam reflector 20 can be reflected by the corresponding reflecting surfaces 21, and further emitted through the lens 30, thereby forming four different light spots, which are combined into a low beam light pattern.
[0042] Under the premise of achieving illumination of the external environment, the paths of light emitted by multiple low-beam light sources 11 can be made independent to avoid mutual interference of light paths, thereby improving the uniformity and stability of low-beam brightness, avoiding overly concentrated hot spots or dark areas, reducing eye fatigue, and improving visual continuity and comfort. Among them, the low-beam light source 11 includes but is not limited to LED.
[0043] Furthermore, by arranging a cut-off line structure 211 at the edge of the reflecting surface 21, part of the light emitted by each low-beam lamp source 11 toward the low-beam reflector 20 can reach the cut-off line structure 211, and be reflected at the cut-off line structure 211 without being able to pass through the lens 30, thereby forming a cut-off line for the low beam, avoiding glare caused by direct strong light to drivers of oncoming vehicles, and ensuring nighttime driving safety.
[0044] Different from the prior art that uses a fixed shading plate to achieve the light-dark cutoff line of the low beam, the present application, on the one hand, not only does not need to set a shading plate with extremely high processing requirements, but can also reduce the number of parts, making the dimension chain shorter and the headlight more stable, but also can make the light-dark cutoff line of the low beam clearer and smoother, thereby reducing the problems of low yield rate caused by the complex structure of the headlight 100. On the other hand, the present application can also avoid the waste of light energy caused by the fixed shading plate blocking the light, so that more light generated by the low beam light source 11 can be emitted and utilized, reducing the loss and waste of light energy, and can improve the light energy utilization rate of the low beam light source 11.
[0045] Therefore, by setting a plurality of low beam light sources 11, a plurality of reflecting surfaces 21 are set in the low beam reflector 20, so that the plurality of reflecting surfaces 21 correspond one-to-one to the plurality of low beam light sources 11, and a light-dark cutoff line structure 211 is set at the edge of the reflecting surface 21, the light type and brightness of the low beam can be further optimized, the structure of the vehicle lamp 100 can be simplified, and the yield rate and light energy utilization rate of the vehicle lamp 100 can be improved.
[0046] Combination Figure 3 As shown, the cut-off line structure 211 may mainly include: a first surface 2111, a second surface 2112 and an inclined surface 2113, wherein the inclined surface 2113 is obliquely connected between the first surface 2111 and the second surface 2112 so that there is a height difference between the first surface 2111 and the second surface 2112.
[0047] Specifically, the cut-off line structure 211 includes a first surface 2111, a second surface 2112 and a slope 2113. The first surface 2111 corresponds to a portion of the edge of the reflecting surface 21, the second surface 2112 corresponds to another portion of the edge of the reflecting surface 21, and the slope 2113 corresponds to another portion of the edge of the reflecting surface 21.
[0048] By making a height difference between the first surface 2111 and the second surface 2112, and obliquely connecting the slope 2113 between the first surface 2111 and the second surface 2112, the first surface 2111, the slope 2113 and the second surface 2112 can all reflect the light from the low beam light source 11, so that it cannot pass through the lens 30, thereby forming a light cut-off line of the low beam. The first surface 2111, the slope 2113 and the second surface 2112 correspondingly affect the shape of the light cut-off line, so that the light cut-off line also has a height difference.
[0049] Combination Figure 1 and Figure 2 As shown, the vehicle lamp 100 may further include: a lens 30 , which is disposed on one side of the low beam reflector 20 , and a cut-off line structure 211 is located on an edge of the reflective surface 21 away from the lens 30 .
[0050] Specifically, by arranging the lens 30 on one side of the low beam reflector 20, on the one hand, the light emitted by the low beam source 11 needs to be refracted through the lens 30 after being reflected by the low beam reflector 20. The lens 30 can focus light, make the light uniform, and limit light scattering, thereby enhancing the lighting effect and improving driving safety. On the other hand, the lens 30 can serve as a cover to protect the low beam source 11, thereby increasing the life of the lamp and enhancing the energy efficiency and maintenance convenience of the lamp 100.
[0051] Furthermore, by locating the cut-off line structure 211 on the edge of the side of the reflecting surface 21 away from the lens 30, the position of the cut-off line structure 211 can be matched with the position of the lens 30, thereby ensuring that a portion of the light emitted by the low-beam lamp source 11 cannot pass through the lens 30 after being reflected by the cut-off line structure 211 on the low-beam reflector 20, thereby ensuring the formation of the low-beam cut-off line and ensuring that the low-beam light type of the vehicle lamp 100 meets regulatory requirements.
[0052] Combination Figure 1 and Figure 2 As shown, the vehicle lamp 100 may further include: a light blocking member 40, which may include a base plate 41 and a bending plate 42, wherein the base plate 41 is disposed on a side of the low beam lamp group 10 adjacent to the lens 30, and the bending plate 42 is connected to the base plate 41 and bent relative to the base plate 41, and the bending plate 42 is used to block part of the light emitted from the low beam lamp source 11 toward the lens 30.
[0053] Specifically, in order to ensure that the low beam pattern of the vehicle meets the requirements of the regulations, it is necessary to ensure that the light emitted by the low beam source 11 is first reflected by the low beam reflector 20, and then refracted through the lens 30, so that the low beam pattern width can be formed in front of the headlight 100, that is, it is necessary to avoid that the light emitted by the low beam source 11 does not pass through the low beam reflector 20 and directly irradiates the lens 30, so as to avoid defects such as uneven light cutoff line and super bright low beam zone III. Among them, in the low beam pattern, the low beam zone III is located above the light cutoff line, also known as the anti-glare zone, indicating the glare condition of the headlight 100.
[0054] If the vehicle lamp 100 is provided with only the cut-off line structure 211 but no light blocking member 40, the low beam light pattern is as follows: Figure 5 As shown in the figure, it can be seen that there are four bright spots in the low beam zone III, which indicates an over-brightness problem.
[0055] By arranging the bottom plate 41 on one side of the low beam lamp group 10 adjacent to the lens 30, the bending plate 42 is connected to the bottom plate 41, and the bending plate 42 is bent relative to the bottom plate 41, that is, the bending plate 42 is at least partially extended in the vertical direction, and the bending plate 42 can block part of the light emitted by the low beam lamp source 11 toward the lens 30, so as to prevent the light emitted by the low beam lamp source 11 from directly irradiating the lens 30 without passing through the low beam reflector 20. The low beam light pattern of the vehicle lamp 100 is as follows: Figure 6 As shown in the figure, it can be seen that there is no bright spot in the low beam zone III, and the brightness is lower, which meets the regulatory requirements.
[0056] In this way, by setting the light blocking member 40 while setting the cut-off line structure 211 in the vehicle lamp 100, glare and stray light can be avoided, the clarity and smoothness of the cut-off line can be ensured, and the brightness of the low beam zone III can be ensured to meet the requirements, thereby achieving further optimization of the low beam light pattern.
[0057] In addition, unlike the prior art in which a fixed sunshade is used to block part of the light emitted from the low beam source toward the lens, the light blocking member 40 includes a bottom plate 41 and a bending plate 42, which can reduce the requirements for processing accuracy of the structure here and reduce manufacturing costs.
[0058] Combination Figure 1 As shown, the low beam lamp group 10 may further include: a circuit board 12, the circuit board 12 may include a main board 121 and a protrusion 122, the protrusion 122 is connected to a side of the main board 121 adjacent to the lens 30, the main board 121 and the protrusion 122 are both provided with a low beam lamp source 11, a plurality of low beam lamp sources 11 are arranged at intervals in the length direction of the main board 121, the bottom plate 41 is provided with a groove 411, and the protrusion 122 is arranged in the groove 411.
[0059] Specifically, by setting the circuit board 12 as a main board 121 and a protrusion 122, and correspondingly, setting a groove 411 on the bottom plate 41, so that the groove 411 can correspondingly avoid the protrusion 122, and the protrusion 122 can be set in the groove 411, thereby realizing the assembly of the circuit board 12 and the light blocking member 40, avoiding the assembly difficulty caused by the light blocking member 40 blocking the circuit board 12 in the assembly direction, and ensuring the normal operation of the low beam light source 11 on the circuit board 12, and ensuring the normal realization of the low beam function of the vehicle lamp 100.
[0060] Furthermore, combined with Figure 1 As shown, there are multiple bending plates 42, and the multiple bending plates 42 are arranged at intervals on the bottom plate 41, and the multiple bending plates 42 correspond to the multiple low-beam light sources 11. In this way, the light emitted by each low-beam light source 11 that is not reflected by the low-beam reflector 20 and directly toward the lens 30 can be blocked by the bending plate 42 accordingly, which is different from setting a large-area bending plate. In this way, while meeting the light blocking requirements of the low-beam light source 11 and ensuring the low-beam light type, it can facilitate the heat dissipation of each low-beam light source 11, avoid poor heat dissipation, ensure the normal operation of the low-beam light source 11, and extend the working life of the low-beam light source 11.
[0061] Combination Figure 1 and Figure 2 As shown, the plurality of bending plates 42 may mainly include: a first bending plate 421 and a second bending plate 422. The first bending plate 421 corresponds to the low beam light source 11 located on the main plate 121, and the first bending plate 421 is configured as a vertical plate perpendicular to the bottom plate 41. Also, the second bending plate 422 corresponds to the low beam light source 11 located on the protruding portion 122, and the second bending plate 422 includes: a first bending section 4221 and a second bending section 4222, the first bending section 4221 is connected to the bottom of the groove 411 and is perpendicular to the bottom plate 41, and the second bending section 4222 is connected to the first bending section 4221 and extends in a direction away from the lens 30.
[0062] Specifically, the main board 121 is farther away from the lens 30 than the protrusion 122. It can be understood that the low beam source 11 located on the main board 121 is far away from the lens 30, and the angle range of the light emitted by the low beam source 11 located on the main board 121 that is not reflected by the low beam reflector 20 and directly toward the lens 30 is smaller. Therefore, by setting the first bending plate 421 on the side of the low beam source 11 located on the main board 121 facing the lens 30, the first bending plate 421 is made to correspond to the low beam source 11 located on the main board 121, and the first bending plate 421 is constructed as a vertical plate perpendicular to the bottom plate 41, so that the first bending plate 421 can meet the light blocking requirement of the low beam source 11 located on the main board 121 and ensure the low beam light type.
[0063] Furthermore, the protruding portion 122 is closer to the lens 30 than the main plate 121. It can be understood that the low beam light source 11 located at the protruding portion 122 is closer to the lens 30, and the angle range of the light emitted by the low beam light source 11 located at the protruding portion 122 and not reflected by the low beam reflector 20 and directly directed toward the lens 30 is larger. Different from the second bending section also being constructed as a vertical plate perpendicular to the bottom plate and increasing the height of the vertical plate, the second bending plate 422 includes: the first bending section 4221 and the second The bending section 4222 connects the first bending section 4221 to the bottom of the groove 411 and is perpendicular to the bottom plate 41, so that the first bending section 4221 can block part of the light that is not reflected by the low beam reflector 20 and directly toward the lens 30, and the second bending section 4222 is connected to the first bending section 4221 and extends in a direction away from the lens 30 until the second bending section 4222 can block another part of the light that is not reflected by the low beam reflector 20 and directly toward the lens 30.
[0064] Therefore, while the second bent plate 422 satisfies the light blocking requirement of the low beam light source 11 located on the protrusion 122 and ensures the low beam light type, it can not only avoid blocking the light from the low beam light source 11 toward the low beam reflector 20 and the light output of the low beam reflector 20, but also facilitate setting the low beam light source 11 in the middle position of the protrusion 122, avoiding the low beam light source 11 being too close to the edge of the circuit board 12, resulting in insufficient thermoelectric separation area, and further causing poor heat dissipation and failure to meet the heat dissipation requirements of the low beam light source 11, and can further improve the working performance of the low beam light source 11.
[0065] In a specific embodiment of the present invention, the number of the reflective surfaces 21 in the lens 30 is four, the number of the low-beam light sources 11 is four, and the number of the bending plates 42 is four.
[0066] In this way, through the design of the circuit board 12 and the light blocking member 40, the light blocking member 40 can avoid the poor heat dissipation problem caused by insufficient thermoelectric separation area due to the low beam light source 11 being too close to the edge of the circuit board 12, and the assembly difficulty problem caused by blocking the circuit board 12 in the assembly direction of the light blocking member 40, while meeting the optical light blocking requirements. This can perfectly balance the three requirements of optics, heat dissipation and assembly, optimize the structural design of the headlight 100, and optimize the working performance of the headlight 100.
[0067] Combination Figure 1 and Figure 4 As shown, the lens 30 is formed with a plurality of transmission surfaces 31 connected in sequence, and the plurality of transmission surfaces 31 correspond one-to-one to the plurality of low-beam light sources 11. The transmission surfaces 31 located at both ends of the plurality of transmission surfaces 31 include: a main transmission surface 311 and an adjustment surface 312. The adjustment surface 312 is connected to the bottom of the main transmission surface 311, and the adjustment surface 312 is bent relative to the main transmission surface 311.
[0068] Specifically, by making multiple transmission surfaces 31 correspond one-to-one with multiple low-beam light sources 11, it can be understood that the multiple transmission surfaces 31 also correspond to multiple reflection surfaces 21, so that the light emitted by the multiple low-beam light sources 11 passes through the structure of multiple reflection surfaces 21 and multiple transmission surfaces 31 that correspond one-to-one and are independent of each other, forming four different light spots, which are combined into a low-beam light pattern.
[0069] Furthermore, in order to ensure that when the vehicle lamp 100 uses the low beam function, it is necessary to provide ambient light for the driver and passengers to help identify the general outline of the road conditions, road signs or pedestrians in the distance, while ensuring that no excessive upward scattered light is generated to avoid causing discomfort or glare to oncoming drivers, it is necessary to form a low beam light pattern with a low beam III zone.
[0070] By making the transmission surfaces 31 located at both ends of the multiple transmission surfaces 31 include: a main transmission surface 311 and an adjustment surface 312, connecting the adjustment surface 312 to the bottom of the main transmission surface 311, and bending the adjustment surface 312 relative to the main transmission surface 311, part of the light emitted by the low beam light source 11 can be emitted through the adjustment surface 312 on the lens 30 after passing through the low beam reflector 20, forming a light type and brightness of the low beam zone III that meet the regulatory requirements. Therefore, under the premise of ensuring the low beam light type and brightness, different from the prior art in which an obvious pattern feature is designed on the lens to refract part of the light to form the low beam zone III, resulting in a more abrupt design of the lens, the present application can not only simplify the processing of parts and reduce the cost, but also make the appearance of the lens 30 smoother, ensure the consistency of the appearance of the lens 30, improve the refinement of the vehicle lamp 100, and enhance the user experience.
[0071] Furthermore, in some embodiments of the present invention, the main transmission surface 311 is configured as a convex surface protruding toward the direction adjacent to the low-beam reflector 20, and the adjustment surface 312 is configured as a concave surface recessed toward the direction away from the low-beam reflector 20. In this configuration, when the light refracted by the low-beam reflector 20 passes through the main transmission surface 311, it can be emitted from the main transmission surface 311 to illuminate the road surface at a short distance, and when the light refracted by the low-beam reflector 20 passes through the adjustment surface 312, it can be emitted from the adjustment surface 312 to illuminate a farther area, helping to identify the road conditions, road signs or the general outline of pedestrians in the distance, while ensuring that no excessively strong upward scattered light is generated, so that when the vehicle lamp 100 uses the low-beam function, it can not only provide the driver with sufficient road lighting, but also reduce the glare effect on oncoming vehicles, thereby improving the safety performance of the vehicle.
[0072] Combination Figure 4As shown, the area of the adjustment surface 312 is smaller than the area of the main transmission surface 311. Specifically, in the low beam light type, the width and brightness of the low beam III zone are both low, and the width and brightness of other areas are both high. By setting the area of the adjustment surface 312 to be smaller than the area of the main transmission surface 311, most of the light emitted from the low beam reflector 20 and entering the lens 30 can be transmitted through the main transmission surface 311, and a small part can be transmitted from the adjustment surface 312, which can ensure that the width and brightness of each area of the low beam light type meet the requirements of regulations, thereby ensuring the normal operation of the low beam function of the vehicle lamp 100.
[0073] Combination Figure 1 and Figure 2 As shown, the vehicle lamp 100 may further include: a radiator 50, a low beam lamp group 10 is mounted on the radiator 50, and a low beam reflector 20 is mounted on the low beam lamp group 10. Specifically, by mounting the low beam reflector 20 on the low beam lamp group 10, the lens 30 corresponds to the low beam reflector 20 in the front-to-back direction, so that the vehicle lamp 100 can be ensured to have a low beam function.
[0074] Taking into account that a large amount of heat is generated when the low beam lamp group 10 is working, resulting in heat accumulation inside the headlight 100, thereby affecting the normal operation of the low beam lamp group 10, a radiator 50 is provided, and the low beam lamp group 10 is installed on a substrate 51 on the radiator 50. In this way, the heat generated by the low beam lamp group 10 can be dissipated through the radiator 50, thereby playing a heat dissipation role, avoiding heat accumulation inside the headlight 100, further ensuring the normal operation of the low beam lamp group 10, and ensuring the normal use of the low beam function of the headlight 100.
[0075] Combination Figure 1 and Figure 2 As shown, the vehicle lamp 100 may further include: a high beam lamp group 60 and a high beam reflector 70. The high beam lamp group 60 is mounted on the radiator 50, the high beam lamp group 60 and the low beam lamp group 10 are located on opposite sides of the radiator 50, and the high beam reflector 70 is arranged on a side of the high beam lamp group 60 away from the low beam lamp group 10.
[0076] Specifically, by locating the high beam lamp group 60 and the low beam lamp group 10 on opposite sides of the radiator 50 respectively, and setting the high beam reflector 70 on the side of the high beam lamp group 60 away from the low beam lamp group 10, the lens 30 can also correspond to the high beam reflector 70 in the front-to-back direction, so that the light emitted by the high beam lamp group 60 can be focused and reflected by the high beam reflector 70, and then transmitted through the lower half of the lens 30 to form the light pattern and brightness of the high beam in front of the headlight 100, which can ensure that the headlight 100 has a high beam function, and make the realization of the low beam function and the high beam function independent of each other.
[0077] Among them, the high beam light type of the vehicle lamp 100 of the present application is as follows: Figure 7As shown. It can be seen that there is no bright and dark cut-off line for the high beam, and the upper arc design of the high beam directs the light to the road surface, thereby ensuring the maximum utilization of the light effect and ensuring a longer lighting distance, and the lower arc design of the high beam ensures the paving effect. That is, compared with the low beam, the high beam has the characteristics of high brightness, large range, and long distance transmission, so that when there is no oncoming vehicle or other road in front of the vehicle, it can provide long-distance lighting for the road ahead of the vehicle to ensure driving safety.

In this way, the heat generated by the high beam lamp group 60 can be dissipated through the radiator 50, thereby playing a heat dissipation role, avoiding heat accumulation inside the headlight 100, further ensuring the normal operation of the high beam lamp group 60, and ensuring the normal use of the high beam function of the headlight 100.
[0079] It should be noted that by installing the low beam lamp group 10 and the high beam lamp group 60 on the radiator 50, and directly positioning the low beam lamp group 10 and the low beam reflector 20, and directly positioning the high beam lamp group 60 and the high beam reflector 70, the dimension chain can be shortened, the assembly accuracy between the optical components can be effectively guaranteed, and the problem of unstable light pattern yield caused by assembly accuracy can be avoided.
