Description

Technical Field

[0001] The present application relates to the technical field of vehicle lighting, and in particular to a simulated lighting component, a vehicle lamp and a vehicle. Background Art

[0002] With the development of vehicle technology, modern vehicle headlights use multiple lighting units to achieve low beam and high beam, thus meeting people's diverse needs for vehicle headlight shapes, but also bringing some appearance problems. Existing vehicle headlights use multiple modules to achieve high beam and low beam lighting. In low beam mode, since the high beam module is not powered on, when people look at the headlight from the outside, they will find that the high beam module part in the headlight is obviously dark, affecting the appearance of the vehicle, especially in the case of narrow opening modules with small vertical directions (such as modules of about 15*100).

[0003] Although there are some solutions to the above problems, such as using structural design to block the high beam module in low beam working conditions, the dark high beam module can still be seen from the side, and there are problems such as limited blocking angle, poor low beam lighting effect and high cost. Therefore, a low-cost and excellent low beam lighting effect car light module solution is urgently needed to meet people's high requirements for the low beam lighting state. Utility Model Content

[0004] In order to solve the above problems, the technical solutions adopted in the embodiments of the present application are as follows:

[0005] The present application discloses a simulated lighting component, comprising:

[0006] A high beam module, comprising a high beam light source and a high beam reflector disposed below the high beam light source, wherein the high beam reflector is used to reflect the high beam light emitted downward by the high beam light source;

[0007] A lens, used for collimating the high beam light reflected by the high beam reflector to form a high beam light pattern;

[0008] A lighting module is provided in the space between the high beam module and the lens, comprising a lighting light source and a lighting reflector provided below the lighting light source, wherein the lighting light source is located above the high beam light source, and the lighting reflector is located below the high beam reflector and the lens;

[0009] Among them, under the low beam working condition, the lighting reflector is used to reflect the lighting light emitted downward by the lighting light source obliquely upward and pass through the lens at a preset upper deflection angle α with the horizontal plane to form a lighting light pattern.

[0010] On the one hand, after the lighting light passes through the lens at a preset upward deflection angle α to the horizontal plane, a corresponding lighting light pattern that is offset upward will be formed on the distant screen. Since the low beam light pattern is usually directed downward at a lower angle, a low beam light pattern will be formed below the distant screen under the low beam condition, and a lighting light pattern will be formed above the screen, and the lighting light pattern will not interfere with and affect the normal presentation of the low beam light pattern; on the other hand, through ingenious conception and design, the lighting module added to the high beam structure shares a narrow opening wide lens with the high beam module, and the lighting module is located in front of the high beam module. The upwardly deflected lighting light is basically completely similar to the upwardly inclined high beam light path and light pattern that can be formed when the high beam module is lit. When the lighting module is lit under the low beam condition, the human eye looks at the inside of the headlight from the front of the lens as if the high beam module is lit, so that the static shape of the high beam module cannot be seen, and there is no dark area in the headlight.

[0011] In the case of a small opening of the optical module, the present application can solve the problem that the high beam module area of ​​the headlamp high and low beam split module is dark and lightless when the low beam is lit alone, and the high beam module area is also like being fully lit in the low beam working condition. When the present embodiment is set in the headlight, there is basically no dark area inside the headlight when viewed from different external angles in the low beam working condition.

[0012] When the low beam is in working condition, the dark area is reduced after the high beam module is lit. It is difficult to see the dark area when observing from a larger angle. The visible angle is large, and the lighting effect of the near and far modules of the headlights is relatively complete, which can meet people's high requirements for the lighting state shape. At the same time, this application does not change the overall structure of the high and low beam modules, but only adds local structures, basically does not change the production process, and the added cost is very low. The position of the lighting module of this application is relatively independent, and the spatial position relative to the low beam module, high beam module, and lens can be defined and set, making the overall shape design more free and flexible.

[0013] As an optional implementation, in the embodiment of the utility model, the upper deflection angle α is 10-15°.

[0014] As an optional implementation, in the embodiment of the utility model, the luminous flux of the lighting light source is 1lm to 50lm.

[0015] As an optional implementation, in an embodiment of the utility model, the lighting reflector and the high-beam reflector are integrally formed.

[0016] As an optional implementation, in the embodiment of the utility model, the distance difference L2 between the lighting light source and the high-beam light source in the vertical direction does not exceed 5 mm.

[0017] As an optional implementation, in the embodiment of the utility model, the distance difference L3 between the highest point of the lighting reflector and the lowest point of the high-beam reflector in the vertical direction is 3 mm to 5 mm.

[0018] As an optional implementation, in an embodiment of the utility model, a distance difference L1 along the horizontal direction between the front end of the lighting reflector close to the lens and the front end of the high-beam reflector close to the lens is 5 mm to 25 mm.

[0019] As an optional implementation, in the embodiment of the utility model, the distance difference L1 along the horizontal direction between the front end of the lighting reflector close to the lens and the front end of the high-beam reflector close to the lens is 13 mm.

[0020] The present application also discloses a vehicle lamp, on which is provided a simulated lighting component as described in any of the aforementioned embodiments.

[0021] The present application also discloses a vehicle, comprising the vehicle light described in any of the aforementioned embodiments.

[0038] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] refer to Figure 1-Figure 3 , the present application provides a simulation lighting component, including:

[0040] The high beam module 200 includes a high beam light source 210 and a high beam reflector 220 disposed below the high beam light source 210 , wherein the high beam reflector 220 is used to reflect the high beam light emitted downward from the high beam light source 210 ;

[0041] The lens 300 is used to collimate the high beam light reflected by the high beam reflector 220 to form a high beam light pattern;

[0042] A lighting module 100 is disposed in the space between the high beam module 200 and the lens 300, and includes a lighting light source 110 and a lighting reflector 120 disposed below the lighting light source 110, wherein the lighting light source 110 is located above the high beam light source 210, and the lighting reflector 120 is located below the high beam reflector 220 and the lens 300;

[0043] In the low beam condition, the lighting reflector 120 is used to reflect the lighting light emitted downward by the lighting light source 110 obliquely upward and pass through the lens 300 at a preset upward deflection angle α with the horizontal plane to form a lighting light pattern.

[0044] Specifically, under the low beam condition, the high beam module 200 does not work, the operating lighting light source 110 is lit, and the lighting light emitted downward is reflected by the lighting reflector 120 and enters the lens 300 at an oblique upward angle. After being collimated by the lens 300, the lighting light passes through the lens 300 at a preset upper deflection angle α with the horizontal plane.

[0045] On the one hand, after the lighting light passes through the lens 300 at a preset upward deflection angle α with the horizontal plane, a corresponding lighting light pattern offset upward will be formed on the distant screen. Since the low beam light pattern is usually directed downward at a lower angle, a low beam light pattern will be formed below the distant screen under the low beam working condition, and a lighting light pattern will be formed above the screen. The lighting light pattern will not interfere with and affect the normal presentation of the low beam light pattern. On the other hand, through ingenious design, the lighting module 100 added to the high beam structure is aligned with the high beam module. The high beam module 200 and the lighting module 100 are located in front of the high beam module 200. The lighting light deflected upward is basically similar to the upward inclined high beam light path and light type that can be formed when the high beam module 200 is actually lit. Therefore, when the lighting module 100 is lit under the low beam condition, the human eye looks at the interior of the headlight from the front of the lens 300 as if the high beam module 200 is lit, so that the static shape of the high beam module 200 cannot be seen, and there is no dark area in the headlight.

[0046] In the case of a small opening of the optical module, the present application can solve the problem that the high beam module 200 area of ​​the headlamp high and low beam split module is dark and lightless when the low beam is lit alone, and the high beam module 200 area is also like being fully lit in the low beam working condition. When the present embodiment is set in the headlight, there is basically no dark area inside the headlight when viewed from different external angles in the low beam working condition.

[0047] When the low beam is in working condition, the dark area is reduced after the high beam module 200 is lit. It is difficult to see the dark area when observing from a larger angle. The visible angle is large, and the lighting effect of the near and far modules of the headlights is relatively complete, which can meet people's high requirements for the lighting state shape. At the same time, this application does not change the overall structure of the high and low beam modules, but only adds local structures, and basically does not change the production process, and the increased cost is very low. The lighting module 100 of this application is relatively independent in position, and the spatial position relative to the low beam module, the high beam module 200, and the lens 300 can be defined and set, making the overall shape design more free and flexible.

[0048] refer to Figure 3 In some embodiments, the upper deflection angle α is 10-15°. When the value is within this range, the light pattern formed on the distant screen is as close to the top as possible to avoid interfering with the low beam pattern and affecting the normal presentation of the low beam pattern. Figure 4 This is the spot light lighting effect diagram when the upper deflection angle α is 10°. It can be seen that the spot light pattern is shifted upward by 10° as a whole, which can effectively avoid interference with the low beam and affect the low beam presentation or cause glare.

[0049] In some embodiments, the luminous flux of the lighting light source 110 is 1 lm to 50 lm. According to tests, when the luminous flux in this numerical range is selected, the maximum energy does not exceed 0.1 lx, which can avoid dazzling the other vehicles. At the same time, the minimum luminous flux of 1 lm can ensure that the lighting light source 110 has sufficient brightness to make the high beam module 200 look like it is lit from the outside.

[0050] refer to Figure 3 In some embodiments, the lighting reflector 120 and the high beam reflector 220 are integrally formed. This can stabilize the relative position between the lighting reflector 120 and the high beam reflector 220 during assembly and use, and avoid large position deviation caused by separate positioning and assembly, which may cause part or all of the high beam module 200 to fail to be lit.

[0051] Of course, such integrated manufacturing can also reduce the number of overall parts of the module and reduce manufacturing costs.

[0052] refer to Figure 1 In some embodiments, the distance difference L2 between the lighting light source 110 and the high beam light source 210 in the vertical direction does not exceed 5 mm. It has been verified that when the distance exceeds 5 mm, the outline of the non-luminous high beam module 200 can be vaguely seen from the outside, and the effect of eliminating the dark area is weak. This may be because when the distance difference L2 increases, the distance between the lighting light source 110 and the lighting reflector 120 is also larger, the light of the lighting light source 110 is more divergent, and the amount of light that can reach the surface of the lighting reflector 120 is reduced. The final lighting light type has low brightness, and the static shape of the high beam module 200 can be seen from the outside.

[0053] refer to Figure 1 In some embodiments, the distance difference L3 between the highest point of the lighting reflector 120 and the lowest point of the high-beam reflector 220 in the vertical direction is 3 mm to 5 mm.

[0054] Since the present application is applied to a narrow opening module, the thickness of the lens 300 in the vertical direction is relatively small. When the distance difference L3 is less than 3mm, the light reflected by the upper part of the lighting reflector 120 does not have enough space to be reflected obliquely upward and ensure that the lighting light with an upper deflection angle α is emitted from the lens 300. In this case, only the light reflected by the lower part of the lighting reflector 120 can form a lighting light pattern, which reduces the area of ​​the lighting light pattern, resulting in part of the high beam module 200 still being visible when observed from the outside at a larger tilt angle under low beam conditions, and the display effect is slightly biased. When the distance difference L3 is greater than 5mm, the outline of the non-luminous high beam module 200 can be vaguely seen from the outside, and the effect of eliminating dark areas is weak. This is because when the distance difference L3 is large, the distance between the lighting reflector 120 and the lens 300 is also far, and part of the light reflected by the lighting reflector 120 is divergent and does not enter the lens 300, resulting in the final lighting light pattern having low brightness, and the static shape of the high beam module 200 can be seen from the outside.

[0055] refer to Figure 1 In some embodiments, a distance difference L1 between the front end of the lighting reflector 120 close to the lens 300 and the front end of the high beam reflector 220 close to the lens 300 in the horizontal direction is 5 mm to 25 mm.

[0056] Since the present application is applied to a narrow opening module, the thickness of the lens 300 in the vertical direction is relatively small. When the distance difference L1 is less than 5 mm, the size of the lighting reflector 120 in the horizontal direction is relatively small, and the space between the rear of the lens 300 and the lighting reflector 120 is not effectively used to form the lighting light. In this case, the area of ​​the lighting light pattern of the light reflected by the lighting reflector 120 is small, resulting in that part of the high beam module 200 can still be seen when observed from the outside at a large tilt angle under low beam conditions, and the display effect is slightly biased. When the distance difference L1 is greater than 25 mm, the outline of the non-luminous high beam module 200 can be vaguely seen from the outside, and the effect of eliminating dark areas is weak. This is because when the distance difference L1 is larger, the size of the lighting reflector 120 in the horizontal direction is also larger, but when the light emitted downward by the lighting light source 110 is concentrated on the lighting reflector 120, the light reflected by the front part of the lighting reflector 120 does not have enough space to reflect forward and upward and ensure that the lighting light with an upper deflection angle α is emitted from the lens 300, that is, a part of the light reflected by the lighting reflector 120 as a whole cannot be effectively utilized, resulting in the final lighting light pattern having a low brightness, and the static shape of the high beam module 200 can be seen from the outside.

[0057] refer to Figure 1In some embodiments, the distance difference L1 between the front end of the lighting reflector 120 close to the lens 300 and the front end of the high beam reflector 220 close to the lens 300 in the horizontal direction is 13 mm. It has been verified that when the distance difference L1 is 13 mm, the size of the lighting reflector 120 in the horizontal direction can be designed to be the most suitable. On the one hand, its size in the horizontal direction is suitable, and the space behind the lens 300 is fully utilized to arrange the lighting reflector 120 to form the lighting light. The lighting light type of the light reflected by the lighting reflector 120 can just simulate the state of the high beam module 200 being lit. The high beam module 200 will not be seen when observed from the outside at a large tilt angle under the low beam condition; on the other hand, the lighting light source 110 is directed to When the light emitted from the bottom is concentrated on the lighting reflector 120, the light reflected by the front part of the lighting reflector 120 also has enough space to be reflected forward and upward and ensure that the lighting light with an upper deflection angle α is emitted from the lens 300, that is, the light reflected by the lighting reflector 120 as a whole can be effectively utilized, and the final lighting light pattern has a high brightness. The outline of the high beam module 200 is completely invisible from the outside, and the high beam module 200 area is completely integrated with the lit low beam module as if it is completely lit (such as Figure 5 ), the lighting effect reaches the expected ideal state.

[0058] The present application also discloses a vehicle lamp, on which is provided the simulated lighting component in any of the aforementioned embodiments.

[0059] The present application also discloses a vehicle, comprising the vehicle light in any of the aforementioned embodiments.

[0060] The above-mentioned means of transportation may be a car, a train, a high-speed train or other means of transportation that requires headlights.

[0061] In the case of a small opening of the optical module, the present application can solve the problem that the high beam module 200 area of ​​the headlamp high and low beam split module is dark and lightless when the low beam is lit alone, and the high beam module 200 area is also like being fully lit in the low beam working condition. When the present embodiment is set in the headlight, there is basically no dark area inside the headlight when viewed from different external angles in the low beam working condition.

[0062] When the low beam is in operation, the dark area is reduced after the high beam module 200 is lit. It is difficult to see the dark area when observed from a larger angle. The visible angle is large, and the lighting effect of the near and far modules of the headlight is relatively complete, which can meet people's high requirements for the lighting state shape. At the same time, this application does not change the overall structure of the high and low beam modules, but only adds local structures, and basically does not change the production process, and the increased cost is very low. The lighting module 100 of this application is relatively independent in position, and the spatial position relative to the low beam module, high beam module 200, and lens 300 can be defined and set, making the design of the overall shape of the headlight more free and flexible.
