Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and more particularly to an optical module. Background Technology

[0002] In recent years, with the development trend of automotive intelligence and the ever-improving regulatory requirements, the automotive lighting field has also made many corresponding adjustments and advancements. The application of intelligent sensors and cameras in automobiles and the widespread use of LED light sources in automotive lighting have brought more possibilities and demands to intelligent automotive headlights. Among them, ADB (Adaptive Driving Beam) technology is widely favored by various OEMs and consumers. LED headlights with ADB function, combined with corresponding camera sensors, can automatically identify oncoming vehicles and control the partial extinguishing of LEDs to create a shadow area, thus avoiding the oncoming vehicle's blinding effect and potential danger.

[0003] Traditional ADB modules typically use lenses with a diameter of around 70mm. They primarily work by using the lens to image the light from the condenser, creating pixels with clearly defined left and right boundaries. The brightness of this type of ADB module is strongly correlated with the size of the lens opening. Generally, the opening size for this type of module is limited to 24mm x 60mm, and the size cannot be further reduced. With the increasing demand for flatter, more streamlined lamp designs, the required top and bottom openings for ADB modules are now generally less than 20mm. How to design ADB modules with such extremely narrow openings is a pressing issue that needs to be addressed. Utility Model Content

[0004] To address the above problems, the technical solution adopted in this application is as follows:

[0005] This application discloses an optical module, including:

[0006] The first high beam reflector group is used to reflect light towards the light-emitting side;

[0007] The second high beam reflector group and / or the accompanying illuminated reflector group are arranged adjacent to the first high beam reflector group in the same plane and have the same orientation as the first high beam reflector group on the light-emitting side, for reflecting light to the light-emitting side.

[0008] A collimating component is disposed on the light-emitting side of each reflector group. The collimating component includes a plurality of adjacent and connected lenses. The collimating component is used to collimate the reflected light so that it is emitted.

[0009] Each of the aforementioned lenses is respectively disposed on the light-emitting side of a first high-beam reflector group or a second high-beam reflector group, for receiving and collimating the reflected light from the first high-beam reflector group or the second high-beam reflector group respectively; or...

[0010] Each of the lenses is respectively disposed on the light-emitting side of a first high beam reflector group or a companion illuminated reflector group, for receiving and collimating the reflected light of a first high beam reflector group or a companion illuminated reflector group respectively.

[0011] Specifically, when the headlight module is used as a high beam module, the light source is located near the focal point of the first high beam reflector and the second high beam reflector respectively. When the first high beam reflector and the second high beam reflector are set up next to each other and reflect light to the light-emitting side at the same time, each lens collimates the reflected light from the corresponding first high beam reflector and the second high beam reflector and then emits it forward to form a combined high beam. The two types of high beam reflectors, the first high beam reflector and the second high beam reflector, which are set up next to each other in the same plane, form a flat and wide optical module in the horizontal direction, which can meet the requirements of the OEM.

[0012] When the headlight module is used as a high beam module with accompanying illumination function, the first high beam reflector and the accompanying illumination reflector are arranged adjacently and reflect light towards the light-emitting side. The lens collimates the reflected light from the corresponding first high beam reflector and emits it forward to form the high beam. When the entire headlight is in low beam mode, the light source of the accompanying illumination reflector is lit. The reflected light from the accompanying illumination reflector is then collimated by the corresponding lens and emitted forward. At the same time, since the lenses are adjacent and connected, once the accompanying illumination light enters the entire collimation component, it will be illuminated, just like the entire high beam module is lit, improving the overall appearance of the headlight. The first high beam reflector and the accompanying illumination reflector, which are arranged adjacently on the same plane, form a wide and flat optical module on the same plane, which can meet the needs of OEMs.

[0013] In some embodiments, the number of the first high beam reflector group and the corresponding lens is four; the number of the accompanying illumination reflector group and the corresponding lens is two, and they are located on the same side of the first high beam reflector group and the corresponding lens.

[0014] In some embodiments, the plurality of lenses are arranged sequentially along a first direction;

[0015] The first direction forms an acute angle α of 0-40° with the vehicle width direction, and the plurality of lenses have a dimension L1 of 80-180mm along the vehicle width direction.

[0016] In some embodiments, the acute angle α formed between the first direction and the vehicle width direction is 14-18°, and the size L1 of the plurality of lenses along the vehicle width direction is 120-150mm.

[0017] In some embodiments, the light-emitting surface of the lens extends along a first direction and forms an acute angle with the collimating direction of the light-incident surface of the lens.

[0018] In some embodiments, the first high beam reflector group and the second high beam reflector group are arranged sequentially along a first direction; or, the first high beam reflector group and the accompanying illumination reflector group are arranged sequentially along a first direction.

[0019] In some embodiments, the vertical dimension H1 of the light-emitting surface of the lens is less than 20 mm.

[0020] In some embodiments, the upper or lower surface of the lens has a dimension L3 of 10mm-30mm along the second direction.

[0021] In some embodiments, the first high beam reflector group includes 2-4 first reflector units arranged sequentially along a first direction; the second high beam reflector group is located on the side of the first high beam reflector group away from the vehicle's central axis and includes a second reflector unit.

[0022] In some embodiments, the focal point Q of the lens has a dimension L5 of 0.5-5.0 mm in front of the root of the corresponding first high beam reflection group and / or second high beam reflection group and / or accompanying illuminated reflection group; or, the focal point Q of the lens has a dimension H3 of 0-1.5 mm above the root of the corresponding first high beam reflection group and / or second high beam reflection group and / or accompanying illuminated reflection group.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] refer to Figures 1-2 This application provides an optical module, including:

[0042] The first high beam reflector group 100 is used to reflect light towards the light-emitting side;

[0043] The second high beam reflector group 210 and / or the accompanying illuminated reflector group 220 are arranged adjacent to the first high beam reflector group 100 in the same plane and have the same orientation as the first high beam reflector group 100 on the light-emitting side, for reflecting light to the light-emitting side.

[0044] A collimating component 300 is disposed on the light-emitting side of each reflector group. The collimating component 300 includes a plurality of adjacent and connected lenses. The collimating component 300 is used to collimate the reflected light so that it can be emitted.

[0045] Each of the aforementioned lenses is respectively disposed on the light-emitting side of a first high-beam reflector group 100 or a second high-beam reflector group 210, for receiving and collimating the reflected light from the first high-beam reflector group 100 or the second high-beam reflector group 210 respectively; or,

[0046] Each of the lenses is respectively disposed on the light-emitting side of the reflected light of a first high beam reflector group 100 or a companion illuminated reflector group 220, for receiving and collimating the reflected light of a first high beam reflector group 100 or a companion illuminated reflector group 220 respectively.

[0047] For details, please refer to Figure 1 When the headlight module is used as a high beam module, the light source is located near the focal point of the first high beam reflector group 100 and the second high beam reflector group 210, respectively. When the first high beam reflector group 100 and the second high beam reflector group 210 are arranged adjacent to each other and reflect light to the light-emitting side at the same time, each lens collimates the reflected light from the corresponding first high beam reflector group 100 and the second high beam reflector group 210 and emits it forward to form a combined high beam. The two high beam reflector groups, the first high beam reflector group 100 and the second high beam reflector group 210, which are arranged adjacent to each other in the same plane, form a flat and wide optical module in the horizontal direction, which can meet the requirements of the OEM.

[0048] refer to Figure 2 When the headlight module functions as a high beam module with accompanying illumination, the first high beam reflector group 100 and the accompanying illumination reflector group 220 are arranged adjacent to each other and reflect light towards the light-emitting side. The lens of the collimating component 300 collimates the reflected light from the first high beam reflector group 100 corresponding to the lens and emits it forward to form high beam. When the entire headlight is in low beam mode, the light source of the first high beam reflector group 100 is not lit, and the collimating component 300 of the high beam module can be seen from outside the headlight, resulting in a poor visual experience. Therefore, in this case, the light source of the accompanying illumination reflector group 220 is lit. The light reflected by the accompanying illumination reflector group 220 is then collimated by the corresponding lens and emitted forward. At the same time, since the lenses are adjacent and connected to each other, once accompanying illumination light enters the entire collimating component 300, it will be illuminated, just like the entire high beam module is illuminated, thus improving the overall visual experience of the headlight. The first high beam reflector group 100 and the accompanying illuminated reflector group 220, which are arranged adjacent to each other in the same plane, form a flat and wide optical module in the same plane, which can meet the needs of the OEM.

[0049] refer to Figure 2 In some embodiments, the first high beam reflector group 100 and the corresponding lens number four; the accompanying illumination reflector group 220 and the corresponding lens number two, and are located on the same side of the first high beam reflector group 100 and the corresponding lens.

[0050] Specifically, the first high beam reflector group 100 and its corresponding lenses number four, which can expand the width of the high beam pattern and ensure that the high beam pattern has a sufficiently large area even when the vertical opening is small. The accompanying illumination reflector group 220 and its corresponding lenses are located on the same side of the first high beam reflector group 100. When the lens corresponding to the accompanying illumination reflector group 220 is illuminated in low beam mode, the light can be diffused and transmitted to the lens corresponding to the first high beam reflector group 100, thereby illuminating the entire collimating component 300 and achieving the effect of accompanying illumination.

[0051] refer to Figure 1 In some embodiments, the plurality of lenses are arranged sequentially along a first direction;

[0052] The first direction forms an acute angle α of 0-40° with the vehicle width direction, and the plurality of lenses have a dimension L1 of 80-180mm along the vehicle width direction.

[0053] Specifically, an acute angle α of 0-40° is set between the first direction and the vehicle width direction, so that the collimating component 300 is tilted relative to the vehicle, resulting in a more three-dimensional static appearance and luminous effect compared to setting it along the vehicle width direction. The multiple lenses have a dimension L1 of 80-180mm along the vehicle width direction, with a larger overall width and a higher degree of flatness, which is beneficial to improving the appearance of the headlights and displaying better luminous effects.

[0054] refer to Figure 1 In some embodiments, the acute angle α formed between the first direction and the vehicle width direction is 14-18°, and the size L1 of the plurality of lenses along the vehicle width direction is 120-150mm.

[0055] Specifically, when the angle is large, the light emitted by the front left and front right lights cannot converge, resulting in a scattered light pattern and poor brightness; when the angle is small, the appearance is flat, and the headlights are visually unappealing. Verification has shown that when the acute angle α formed between the first direction and the vehicle width direction is 14-18°, the angle setting is more suitable, allowing more light to converge and be emitted towards the central axis closer to the vehicle's length, thus forming a suitable light pattern and ensuring brightness. The multiple lenses have a dimension L1 of 120-150mm along the vehicle width direction, which is relatively large overall, resulting in stable light output.

[0056] refer to Figure 1 In some embodiments, the light-emitting surface 302 of the lens extends along a first direction and forms an acute angle with the collimating direction of the light-incident surface 301 of the lens.

[0057] Specifically, after the light reflected by the reflector enters the incident surface 301 of the corresponding lens, the light is transmitted along the collimation direction. When it reaches the exit surface 302 of the lens, since the collimation direction between the exit surface 302 and the incident surface 301 forms an acute angle, the light is refracted and exits at an acute angle to the exit surface 302 and converges towards the central axis of the vehicle's length direction, which is beneficial for the convergence and integration of the light patterns emitted by the headlights on both sides.

[0058] refer to Figure 1 In some embodiments, the first high beam reflector group 100 and the second high beam reflector group 210 are arranged sequentially along a first direction; or, refer to Figure 2 The first high beam reflector group 100 and the accompanying illumination reflector group 220 are arranged sequentially along the first direction.

[0059] Specifically, when the lenses are arranged sequentially along the first direction, the first high beam reflector group 100 and the second high beam reflector group 210 are arranged sequentially along the first direction; or, the first high beam reflector group 100 and the accompanying illumination reflector group 220 are arranged sequentially along the first direction, so that they can cooperate with the compatible lenses to ensure that the direction and brightness of the light emitted from each lens are consistent, and avoid the problem of different directions and brightness of the light emitted from each lens due to the free arrangement of each reflector group, which reduces the visual experience and driving safety.

[0060] refer to Figure 3 and Figure 4 In some embodiments, the vertical dimension H1 of the light-emitting surface 302 of the lens is less than 20 mm. Through the design of this application, the vertical dimension of the light-emitting surface 302 of the lens can be made less than 20 mm, thus meeting the requirements of a flattened design.

[0061] refer to Figure 3 and Figure 4 In some embodiments, the upper or lower surface of the lens has a dimension L3 of 10mm-30mm along the second direction. Specifically, the second direction is the length direction of the vehicle. When the headlight module has an accompanying illumination function, in low beam mode, when the light source of the accompanying illumination reflector group 220 is illuminated, the reflected light from the accompanying illumination reflector group 220 is collimated by the corresponding lens and emitted forward to illuminate the entire collimating component 300. In this case, when the upper or lower surface of the lens has a dimension L3 of 10mm-30mm along the second direction, the thickness of the collimating component 300 along the length direction of the vehicle is relatively large. After being illuminated, the collimating component 300 becomes bright as a whole, which is sufficient to cover the reflector group and the light source behind it. This prevents the first high beam reflector group 100 and the high beam light source point behind the lens from being seen from the outside in low beam mode, further improving the appearance of the headlight.

[0062] refer to Figure 1In some embodiments, the first high beam reflector group 100 includes 2-4 first reflector units 110 arranged sequentially along a first direction; the second high beam reflector group 210 is located on the side of the first high beam reflector group 100 away from the vehicle's central axis and includes a second reflector unit 211.

[0063] Specifically, each first high beam reflector group 100 includes multiple first reflector units 110. The multiple first reflector units 110 disperse the light emission, which can improve the uniformity of the high beam pattern display. Moreover, the individual first reflector unit 110 is small in size. Even 2-4 reflector units occupy less space than a large reflector, thereby reducing the space occupied by the entire first high beam reflector group 100 and avoiding taking up too much space inside the headlight. The second high beam reflector group 210 includes only one second reflector unit 211. This is because the second high beam reflector group 210 is located on the side of the first high beam reflector group 100 away from the vehicle's central axis. In this case, the high beam light emitted forward by the second high beam reflector groups 210 in the left and right headlights forms the outer ring of the entire vehicle's high beam pattern. Therefore, setting a single second reflector unit 211 concentrates the light emission brightness, which can enhance the clarity of the outer ring of the high beam pattern.

[0064] Furthermore, in the direction along which the first high beam reflector group 100 and the second high beam reflector group 210 are arranged sequentially, the number of first reflector units 110 included in the first high beam reflector group 100 closer to the vehicle's central axis is greater than the number of first reflector units 110 included in the first high beam reflector group 100 farther from the vehicle's central axis. Specifically, in the two headlights on the left and right sides, the high beam light emitted forward by the second high beam reflector group 210 farther from the vehicle's central axis forms a light pattern on the outer ring of the entire vehicle's high beam pattern. Therefore, it includes fewer first reflector units 110, resulting in a more concentrated luminous brightness, which is beneficial for enhancing the clarity of the outer ring of the high beam pattern.

[0065] refer to Figure 5 In some embodiments, the focal point Q of the lens has a dimension L5 of 0.5-5.0 mm in front of the root of the corresponding first high beam reflector group 100 and / or second high beam reflector group 210 and / or accompanying illuminated reflector group 220.

[0066] Specifically, the light emitted from the light source is reflected by the reflector group and converges to the focal point Q of the lens, then enters the lens in front. When the lens adopts the above dimensions: the vertical dimension of the light-emitting surface 302 is less than 20mm and the dimension of the upper or lower surface of the lens along the second direction is 10mm-30mm, if the focal point Q of the lens is more than 5.0mm away from the corresponding reflector group in front of L5, the focal point Q is relatively close to the lens, the light entering the lens is more concentrated, and it cannot evenly illuminate each lens. When used as a high beam, the high beam pattern area is also smaller. If the focal point Q of the lens is less than 0.5mm away from the corresponding reflector group in front of L5, the focal point Q is relatively far from the lens, and the light at the upper and lower edges of the beam will not be able to enter the lens, resulting in an incomplete high beam pattern. Therefore, selecting a lens focal point Q with a dimension L5 of 0.5-5.0 mm in front of the root of the corresponding first high beam reflector group 100 and / or second high beam reflector group 210 and / or accompanying illumination reflector group 220 can ensure that the light entering the lens is dispersed and can evenly illuminate each lens, presenting a suitable high beam beam area when used as a high beam, and having a complete beam pattern.

[0067] refer to Figure 5 In some embodiments, the focal point Q of the lens is 0-1.5 mm above the root of the corresponding first high beam reflector group 100 and / or second high beam reflector group 210 and / or accompanying illuminated reflector group 220.

[0068] When the lens adopts the above dimensions: the vertical dimension of the light-emitting surface 302 is less than 20mm and the dimension of the upper or lower surface of the lens along the second direction is 10mm-30mm, if the focal point Q of the lens is more than 1.5mm above the root of the corresponding reflector group or is below the root, light rays at the upper and lower edges of the beam will not be able to enter the lens, resulting in an incomplete high beam pattern and a smaller beam area. Therefore, selecting a focal point Q of the lens with a dimension H3 of 0-1.5mm above the root of the corresponding first high beam reflector group 100 and / or second high beam reflector group 210 and / or accompanying illuminated reflector group 220 allows for a suitable high beam area and a complete beam pattern when used as a high beam.
