[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 2 , the present application provides an optical module, comprising:
[0040] 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;
[0041] 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;
[0042] The auxiliary lighting reflector 300 is arranged on the side of the high beam reflector 110 in the width direction, and is used to reflect the lighting light emitted by the auxiliary lighting light source and emit it forward in the low beam mode;
[0043] An auxiliary lighting light source, disposed inside the auxiliary lighting reflector 300, configured to light up in a low beam mode;
[0044] Among them, the high beam lens 200 includes an auxiliary light incident surface 210 close to the auxiliary lighting reflector 300 and a total reflection surface 220 away from the auxiliary lighting reflector 300; the auxiliary light incident surface 210 is located in front of the auxiliary lighting reflector 300, and is used for allowing the lighting light reflected by the auxiliary lighting reflector 300 to enter, and the total reflection surface 220 and the auxiliary light incident surface 210 are arranged opposite to each other on the high beam lens 200, and are used to totally reflect the lighting light into the high beam lens 200 along the width direction.
[0045] Specifically, in the low beam mode, the lighting light emitted by the low beam mode lighting light source is reflected by the auxiliary lighting reflector 300 and then enters 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.
[0046] like Figure 5 As shown, when the low beam is working, the high beam light source is off, and the low beam mode lights up the light source and 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;
[0047] like Figure 4 As shown, when the low beam mode is on, the maximum screen energy is 0.164lx 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 1lx (625cd)).
[0048] 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 auxiliary lighting reflector 300, auxiliary lighting light source and other components are small in size and are arranged behind the high beam lens 200. They cannot be seen from the outside when the car lights are completely off, and do not change the shape contour of the light-emitting surface of the high beam module. Compared with being arranged in other parts, the optical module still has static beauty when the light is not on.
[0049] According to tests, the maximum projection energy of the high beam lens 200 on the distant screen after being lit is 0.164 lx. The brightness is low and does not affect the normal low beam lighting effect. The high beam lens 200 can be evenly lit after multiple total reflections. The overall visual effect of the headlights is full when illuminated in low beam mode, and the entire headlights are coordinated in shape in low beam mode and high beam mode.
[0050] like Figure 1 In some examples, the auxiliary lighting reflector 300 is located on a side of the high beam reflector 110 in a width direction and is connected to the high beam reflector 110 .
[0051] Specifically, the auxiliary lighting reflector 300 and the high beam reflector 110 are integrally formed and integrated on the high beam reflector 110, with a high degree of integration. This solution does not need to assemble extra components separately, and the structure is simpler. It 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. Since it is only necessary to form the auxiliary lighting reflector 300 and the high beam reflector 110 as one piece, there is no need to open a separate mold, and the cost is basically not increased.
[0052] like Figure 1 In some examples, the auxiliary lighting reflector 300 and the auxiliary lighting light source are located on the left and / or right side of the high beam reflector 110 in the width direction.
[0053] Specifically, the auxiliary lighting reflector 300 and the auxiliary lighting light source inside it can be arranged on either side or both sides of the high beam reflector 110, and its position can be flexibly set according to design requirements, making the design of the module appearance more free and beautiful.
[0054] In some examples, the internal reflection surface of the auxiliary lighting reflector 300 is a parabola, and the auxiliary lighting light source is located at or near the focus of the internal reflection surface.
[0055] Specifically, the parabola has only one focus. When in use, the auxiliary lighting light source is set at or near the focus. After the lighting light is reflected by the parabola of the auxiliary lighting reflector 300, it can be emitted forward in parallel and evenly illuminate various parts of the auxiliary light incident surface 210. After entering the high beam lens 200, it can evenly illuminate various parts of the total reflection surface 220. After total reflection, the high beam lens 200 can be evenly illuminated, and the lighting effect is good.
[0056] like Figure 1 In some examples, the angle α between the total reflection surface 220 and the auxiliary light incident surface 210, or the angle α between the total reflection surface 220 and the tangent surface of the auxiliary light incident surface 210 close to the total reflection surface 220 is 50°-80°. It has been verified that when the angle α shown in the figure is set in the range of 50°-80°, the total reflection surface 220 can efficiently reflect most of the lighting light and transmit it to the part away from the total reflection surface 220 along the width direction of the high beam lens 200, so as to achieve the purpose of efficiently lighting the high beam lens 200, and the overall visual effect of the headlight is fuller when the low beam mode is illuminated. The whole headlight has the same shape in the low beam mode and the high beam mode, which avoids the angle setting being 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 the part away from the total reflection surface 220, resulting in too low brightness of the high beam lens 200.
[0057] In some examples, the luminous flux of the auxiliary lighting light source is 10lm-50lm.
[0058] Specifically, when the luminous flux of the auxiliary lighting light source 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, the luminous flux of the low beam mode lighting light source is selected to be 10lm-50lm to achieve the expected functional effect.
[0059] like Figure 3In 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 directly opposite to 2-4 high-beam reflectors 110 front and back and protrudes toward one side of the high-beam reflector 110.
[0060] Specifically, each high beam unit 201 can collimate the high beam reflected by its corresponding 2-4 high beam reflectors 110 and emit the collimated high beam light. The number density of the high beam reflectors 110 is greater than the number density of the high beam units 201. The multiple high beam reflectors 110 densely arranged in the width direction and the multiple high beam light sources therein can increase the uniformity of the distribution of the light entering the high beam lens 200 in the width direction; the multiple side-by-side high beam units 201 can fully expand the width of the high beam light pattern; the protruding high beam light entrance unit surface 201a can collimate the high beam light in the width and / or vertical direction, and the light pattern is displayed uniformly.
[0061] like Figure 1 In some examples, the auxiliary lighting reflector 300 and the auxiliary lighting light source 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 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.
[0062] 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 auxiliary lighting reflector 300 and the auxiliary lighting light source are located on the side of the high-beam lens 200 close to the side of the vehicle, 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.
[0063] Therefore, in this embodiment, the auxiliary lighting reflector 300 and the auxiliary lighting light source 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, 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 lighting effect is achieved.
[0064] like Figure 1In some examples, the auxiliary lighting reflector 300 and the auxiliary lighting light source therein are located on one 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 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.
[0065] Specifically, when the auxiliary lighting reflector 300, the auxiliary lighting light source, 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 away from the middle of the vehicle is far away from the light collecting component, so setting its width 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 lighting light effect is achieved.
[0066] The present application also discloses a vehicle lamp, comprising the optical module described in any one of the embodiments.
[0067] The present application also discloses a vehicle, comprising the vehicle light in the aforementioned embodiment.
[0068] The above-mentioned means of transportation can be a car, a train, a high-speed train or other means of transportation that requires headlights. By adopting the above-mentioned headlights, few additional components are added, the structure is simple, and the parts and assembly tolerances caused by adding too many parts can be reduced, and the optical accuracy can be guaranteed; since there are few additional components, the cost is saved; the additional auxiliary lighting reflector 300, auxiliary lighting light source and other components are small in size and are arranged behind the high beam lens 200. When the headlights are completely off, they will not be seen from the outside, and the shape contour of the high beam module's light-emitting surface will not be changed. Compared with being arranged in other parts, the optical module still has static beauty when the light is not on.
[0069] After testing, it was found that after the high beam lens 200 was lit, the projection energy brightness on the distant screen was not large and did not affect the normal low beam lighting effect. Moreover, the high beam lens 200 could be evenly lit after multiple total reflections. When illuminated in low beam mode, the overall visual effect of the headlights was full, and the entire headlights presented a coordinated shape in low beam mode and high beam mode.
