Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle lighting technology, and in particular to an optical module, a vehicle lamp and a vehicle. Background Art
[0002] With the emergence of LED and the development of automobile lighting, how to design a car headlight is no longer a problem. Effectively combining the cost, personalization, efficiency and performance of the headlight module has become the goal pursued by people. Among them, the high and low beams are an important part of the headlight module, which mainly includes two types: high and low beam integrated modules and high and low beam split modules.
[0003] In the traditional high beam and low beam split modules, both high and low beam modules are lit in high beam mode, but only low beam module is lit in low beam mode, and the high beam module is dark, which creates a visual sense of emptiness, makes the overall shape of the lamp inconsistent, and the appearance is not beautiful when lit. Although there are some improvements to the high beam module in the existing schemes, they all require the addition of complex components, the static appearance is not beautiful when not lit, and bring additional assembly tolerances and reduced optical accuracy; and the addition of complex components also increases costs; in addition, the local brightness of the high beam module after lighting greatly affects the normal low beam light effect and the light is uneven, the visual effect is not full, and it is difficult to ensure the coordination of the lamp shape. 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] An optical module, comprising:
[0006] A high-beam light source module, comprising a high-beam reflector and a high-beam light source inside the high-beam reflector, wherein the high-beam reflector is used to reflect the high-beam light emitted by the high-beam light source and emit it forward in a high-beam mode;
[0007] A high beam lens, used for collimating the high beam reflected by the high beam reflector to form a high beam light pattern;
[0008] A low beam mode lighting light source is disposed on the side of the high beam reflector in the width direction and is located in front of the high beam reflector in the front-rear direction, and is configured to light up in the low beam mode;
[0009] A light collecting component, disposed in front of the low beam mode lighting light source, for collecting the lighting light emitted by the low beam mode lighting light source;
[0010] Among them, the high beam lens includes an auxiliary light incident surface close to the light collecting component and a total reflection surface far away from the light collecting component. The auxiliary light incident surface is arranged in front of the light collecting component for allowing the lighting light gathered by the light collecting component to enter. The total reflection surface is arranged opposite to the auxiliary light incident surface for totally reflecting the lighting light into the high beam lens along the width direction.
[0011] In some examples, the light collecting component is located on a side of the high beam lens in the width direction and is bonded to the auxiliary light incident surface.
[0012] In some examples, the light collecting component is located on the left and / or right side of the high beam lens in the width direction, and the low beam mode lighting light source is located on the left and / or right side of the high beam reflector in the width direction.
[0013] In some examples, the angle α between the auxiliary light incident surface and the total reflection surface is 40°-60°.
[0014] In some examples, the luminous flux of the light source illuminated in the low beam mode is 10lm-50lm.
[0015] In some examples, there are multiple high-beam reflectors, which are arranged side by side in sequence along the width direction; and the high-beam lens includes multiple high-beam units arranged side by side along the width direction, and the high-beam unit includes a high-beam light incident unit surface, and each high-beam light incident unit surface is respectively and one-to-one arranged in front of each high-beam reflector and protrudes toward one side of the high-beam reflector.
[0016] In some examples, the light collecting component and the low beam mode lighting light source are located on a side of the high beam lens close to the middle of the vehicle;
[0017] In the vehicle width direction from the vehicle center to the vehicle side, the front-rear thickness of the high beam unit near the vehicle center is greater than the front-rear thickness of the high beam unit far from the vehicle center.
[0018] In some examples, the light collecting component and the low beam mode lighting light source are located on a side of the high beam lens close to the middle of the vehicle;
[0019] In the vehicle width direction from the vehicle center to the vehicle side, the width of the high beam unit near the vehicle center is greater than the width of the high beam unit far from the vehicle center.
[0020] A vehicle lamp comprises the optical module described in any one of the items.
[0021] The present application also discloses a vehicle, comprising the vehicle lamp described in the aforementioned embodiment.
[0022] In the present embodiment, the additional components are few and the structure is simple, which can reduce the parts and assembly tolerances caused by adding too many parts and ensure optical accuracy. Since the additional components are few, the cost is saved. The additional light-collecting components and other components are small in size and are located behind the high-beam lens. When the headlights are completely off, they cannot be seen from the outside and do not change the shape of the light-emitting surface of the high-beam module. Compared with being located in other parts, the optical module still has static beauty when the lights are not on.
[0023] The low beam mode lighting light source is located in front of the high beam reflector in the front-to-back direction, and is at a shorter distance from the auxiliary light incident surface of the high beam lens, shortening the path of the lighting light entering the high beam lens, thereby improving the lighting brightness of the high beam lens.
[0024] After the high beam lens of the present application is lit, the projection energy on the distant screen is appropriate and does not affect the normal low beam lighting effect. After multiple total reflections, the high beam lens can be evenly lit. When the low beam mode is illuminated, the overall visual effect of the headlight is full, and the entire headlight presents a coordinated shape in the low beam mode and the high beam mode.

[0042] 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.
[0043] refer to Figure 1-Figure 2 , the present application provides an optical module, comprising:
[0044] The high-beam light source module 100 includes a high-beam reflector 110 and a high-beam light source inside the high-beam reflector 110, wherein the high-beam reflector 110 is used to reflect the high-beam light emitted by the high-beam light source and emit it forward in the high-beam mode;
[0045] A high beam lens 200, used for collimating the high beam reflected by the high beam reflector 110 to form a high beam light pattern;
[0046] The low beam mode lighting light source 300 is disposed on the side of the high beam reflector 110 in the width direction and is located in front of the high beam reflector 110 in the front-rear direction, and is configured to light up in the low beam mode;
[0047] The light collecting component 400 is disposed in front of the low beam mode lighting light source 300 and is used to collect the lighting light emitted by the low beam mode lighting light source 300;
[0048] Among them, the high beam lens 200 includes an auxiliary light incident surface 210 close to the light collecting component 400 and a total reflection surface 220 away from the light collecting component 400. The auxiliary light incident surface 210 is arranged in front of the light collecting component 400, and is used for allowing the lighting light gathered by the light collecting component 400 to enter. The total reflection surface 220 is arranged opposite to the auxiliary light incident surface 210, and is used to totally reflect the lighting light into the high beam lens 200 along the width direction.
[0049] Specifically, in the low beam mode, the lighting light emitted by the low beam mode lighting light source 300 is converged by the light collecting component 400 and then incident on the high beam lens 200 from the auxiliary light incident surface 210. After the lighting light reaches the total reflection surface 220, it is totally reflected multiple times inside the high beam lens 200 through the front and rear surfaces of the high beam lens 200, and is transmitted along the width direction of the high beam lens 200 to a position away from the total reflection surface 220, thereby achieving the purpose of lighting the high beam lens 200 in the low beam mode.
[0050] The low beam mode lighting light source 300 is located in front of the high beam reflector 110 in the front-to-rear direction and is at a shorter distance from the auxiliary light incident surface 210 of the high beam lens 200 , shortening the path of the lighting light entering the high beam lens 200 and improving the lighting brightness of the high beam lens 200 .
[0051] like Figure 5 As shown, when the low beam is working, the high beam light source is off, and the low beam mode lighting light source 300 lights up the high beam module, which can meet the requirement of the high beam module emitting dim light in the low beam mode from the visual effect;
[0052] like Figure 4 As shown, when the light source 300 is turned on in low beam mode, the maximum screen energy is 0.164 lx and there is almost no light below 10°, which can effectively avoid the problem of low beam zone 3 being too bright as required by regulations (the regulations stipulate that it cannot exceed 1 lx (625 cd)).
[0053] The present application adopts the above-mentioned technical solution, with few additional components and a simple structure, which can reduce the parts and assembly tolerances caused by adding too many parts and ensure optical accuracy; since there are few additional components, costs are saved; the additional light-collecting component 400 and other components are small in size and are located behind the high-beam lens 200, and cannot be seen from the outside when the headlights are completely off, and do not change the shape and contour of the light-emitting surface of the high-beam module. Compared with being located in other parts, the optical module still has static beauty when the lights are not on.
[0054] After the high beam lens 200 of the present application is lit, the maximum projection energy on the distant screen is 0.164lx, the brightness is appropriate and does not affect the normal low beam lighting effect, and the high beam lens 200 can be evenly lit after multiple total reflections. When the low beam mode is illuminated, the overall visual effect of the headlight is full, and the entire headlight presents a coordinated shape in the low beam mode and the high beam mode.
[0055] like Figure 1 In some examples, the light collecting component 400 is located on the side of the high beam lens 200 in the width direction and is bonded to the auxiliary light incident surface 210 .
[0056] Specifically, the light collecting component 400 and the high beam lens 200 are integrally formed and integrated on the high beam lens 200, and the integration is high, so that the present solution does not need to assemble extra components separately, and the structure is simpler, which directly avoids the parts and assembly tolerance problems caused by adding parts, and the optical accuracy of the lamp's own function is completely unaffected; the light collecting component 400 can adopt a structure such as a concentrator, because it only needs to be integrally formed with the high beam lens 200, and there is no need to open a separate mold, and the cost is basically not increased.
[0057] like Figure 1In some examples, the light collecting component 400 is located on the left and / or right side of the high beam lens 200 in the width direction, and the low beam mode lighting light source 300 is located on the left and / or right side of the high beam reflector 110 in the width direction.
[0058] Specifically, the light collecting component 400 and the low beam mode lighting light source 300 can be arranged on either side of the high beam lens 200, and their positions can be flexibly set according to design requirements, making the design of the lens appearance and shape more free and beautiful.
[0059] like Figure 1 In some examples, the angle α between the auxiliary light-entering surface 210 and the total reflection surface 220 is 40°-60°. It has been verified that when the angle α between the auxiliary light-entering surface 210 and the total reflection surface 220 is set in the range of 40°-60°, the total reflection surface 220 can efficiently fully reflect most of the lighting light, and transmit it along the width direction of the high-beam lens 200 to a portion away from the total reflection surface 220, thereby achieving the purpose of efficiently lighting the high-beam lens 200, and the overall visual effect of the headlight is fuller when illuminated in low-beam mode. The entire headlight has the same appearance in low-beam mode and high-beam mode, avoiding the situation where the angle is too small or too large, resulting in most of the lighting light not being able to be fully reflected and scattered, and not enough lighting light being transmitted along the width direction of the high-beam lens 200 to a portion away from the total reflection surface 220, resulting in the high-beam lens 200 being too low in brightness.
[0060] In some examples, the luminous flux of the low beam mode lighting light source 300 is 10lm-50lm. Specifically, when the luminous flux is greater than 50lm, the screen energy value is too large, the high brightness of the low beam zone 3 does not meet the regulatory requirements, and will affect the low beam light effect; when the luminous flux is less than 10lm, the lighting light is not enough to evenly light up the high beam lens 200, and the high beam module is still not lit in the low beam mode. Therefore, selecting the luminous flux of the low beam mode lighting light source 300 to be 10lm-50lm can achieve the expected functional effect.
[0061] like Figure 1 In some examples, there are multiple high-beam reflectors 110, which are arranged side by side in sequence along the width direction; and the high-beam lens 200 includes multiple high-beam units 201 arranged side by side along the width direction, and the high-beam unit 201 includes a high-beam light incident unit surface 201a, and each high-beam light incident unit surface 201a is respectively and one-to-one arranged in front of each high-beam reflector 110 and protrudes toward one side of the high-beam reflector 110.
[0062] Specifically, the high beam unit 201 can collimate the high beam light reflected by the corresponding high beam reflector 110, and multiple high beam units 201 can expand the width of the high beam light pattern; the protruding high beam light incident unit surface 201a can collimate the high beam light in the width direction and / or vertical direction, and the light pattern is displayed uniformly.
[0063] like Figure 1 In some examples, the light collecting component 400 and the low beam mode lighting light source 300 are located on a side of the high beam lens 200 close to the middle of the vehicle (i.e. Figure 1 in the vehicle width direction from the middle of the vehicle to the side of the vehicle, the front-to-rear direction thickness of the high beam unit 201 near the middle of the vehicle is greater than the front-to-rear direction thickness of the high beam unit 201 away from the middle of the vehicle.
[0064] Due to regulations and aesthetic requirements for vehicle design, the closer the high beam lens 200 is to the center of the vehicle, the larger its design volume is. In this case, if the light collecting component 400 and the low beam mode lighting light source 300 are located on the side of the high beam lens 200 close to the side of the vehicle, then when the lighting light is transmitted from the side of the vehicle to the middle of the vehicle in the high beam lens 200, the brightness is too small to evenly light up the entire high beam lens 200.
[0065] Therefore, in this embodiment, the light collecting component 400 and the low beam mode lighting light source 300 are arranged on the side of the high beam lens 200 close to the middle of the car, and the auxiliary light incident surface 210 and the total reflection surface 220 are also correspondingly arranged on the side of the high beam lens 200 close to the middle of the car. After the lighting light passes through the total reflection surface 220, it will be reflected from the middle of the car ( Figure 1 Left side of the center) to the side of the car ( Figure 1 at the same time, the high beam unit 201 far away from the middle of the vehicle is far away from the light collecting component 400, so setting its front-to-back thickness to be small can shorten the optical path of the lighting light in the high beam unit 201, improve the lighting speed of the high beam lens 200 and reduce light loss, thereby ensuring that the expected light effect is achieved.
[0066] like Figure 1 In some examples, the light collecting component 400 and the low beam mode lighting light source 300 are located on the side of the high beam lens 200 close to the middle of the vehicle (that is, Figure 1 in the vehicle width direction from the middle of the vehicle to the side of the vehicle, the width of the high beam unit 201 near the middle of the vehicle is greater than the width of the high beam unit 201 away from the middle of the vehicle.
[0067] Specifically, when the light collecting component 400, the low beam mode lighting light source 300, the auxiliary light incident surface 210, and the total reflection surface 220 are arranged on the side of the high beam lens 200 close to the middle of the vehicle, the high beam unit 201 far away from the middle of the vehicle is far away from the light collecting component 400, and thus setting its width to be small can shorten the optical path of the lighting light in the high beam unit 201, thereby improving the lighting speed of the high beam lens 200 and reducing light loss, thereby ensuring that the expected lighting light effect is achieved.
[0068] The present application also discloses a vehicle lamp, comprising the optical module described in any one of the embodiments.
[0069] The present application also discloses a vehicle, comprising the vehicle light in the aforementioned embodiment.
[0070] The above-mentioned means of transportation can be a car, a train, a high-speed train or other means of transportation that requires headlights. This application adopts the above-mentioned technical solution, with few additional components and a simple structure, which can reduce the parts and assembly tolerances caused by adding too many parts, and can ensure optical accuracy; since there are few additional components, costs are saved; the additional light-collecting component 400 and other components are small in size and are located behind the high-beam lens 200, and will not be seen from the outside when the headlights are completely off, and will not change the shape and contour of the high-beam module's light-emitting surface. Compared with being located in other parts, the optical module still has static beauty when the light is not on.
[0071] After the high beam lens 200 of the present application is lit, the projection energy on the distant screen is appropriate and does not affect the normal low beam lighting effect. After multiple total reflections, the high beam lens 200 can be evenly lit. When the low beam mode is illuminated, the overall visual effect of the headlight is full, and the entire headlight presents a coordinated shape in the low beam mode and the high beam mode.
