Description

Technical Field

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

[0002] With the rise of intelligent and personalized vehicles, consumers are placing higher demands on the functionality and appearance of automotive lighting. On the one hand, people seek a safer and more efficient lighting experience, with more comprehensive light coverage at night or in complex road conditions; on the other hand, they hope that headlights can become a distinctive identifier for their vehicles. Simultaneously, intensifying competition in the automotive industry forces manufacturers to enhance product competitiveness through innovative features. Currently, traditional high and low beam headlights are separate modules. In low beam mode, the high beam module area is dark, creating a visual void and resulting in a lack of harmony and aesthetics in the overall headlight design, as well as poor low beam illumination.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art, and to provide an optical module, a vehicle light, and a vehicle.

[0005] According to one aspect of this application, an optical module is provided, including a first light guide component, an accompanying light source, and a reflector; the first light guide component has a first light emitting region and a second light emitting region; the accompanying light source is configured to illuminate one of the first light emitting region and the second light emitting region; the reflector is disposed between the first light guide component and the accompanying light source, and the reflector has a reflective surface on the side of the reflector facing the accompanying light source, the reflective surface being configured to receive a portion of the light provided by the accompanying light source and reflect the light to the other of the first light emitting region and the second light emitting region, the second light emitting region being disposed on the side of the first light emitting region away from the reflective surface.

[0006] In one embodiment, the angle between the reflective surface and the horizontal plane is β, which satisfies: 0°≤β≤20°.

[0007] In one embodiment, the light source also includes a reflector, wherein the light emitted by the accompanying light source toward the reflector is reflected by the reflector and directed toward the first light-emitting area, and the light emitted by the accompanying light source toward the reflective surface is reflected by the reflective surface and directed toward the second light-emitting area.

[0008] In one embodiment, a second light guide component is further included, which is disposed between the accompanying light source and the first light guide component. The accompanying light source includes a first LED and a second LED. The light emitted by the first LED is adjusted by the second light guide component, with part of it directed toward the first light-emitting area and part of it directed toward the reflective surface, and then reflected by the reflective surface toward the second light-emitting area. The light emitted by the second LED is adjusted by the second light guide component to be directed toward the reflective surface, and then reflected by the reflective surface toward the second light-emitting area.

[0009] In one embodiment, the first LED and the second LED are disposed on the same printed circuit board.

[0010] In one embodiment, the reflective surface has a uniform texture.

[0011] In one embodiment, the device further includes a bracket, wherein the first light guide component is disposed on the bracket; the bracket is provided with the reflective surface.

[0012] In one embodiment, the first light guide component and the accompanying light source are disposed on the same side of the reflective surface.

[0013] According to another aspect of this application, a vehicle lamp is provided, including any of the optical modules described above.

[0014] According to another aspect of this application, a vehicle is provided, including the aforementioned vehicle lights.

[0015] The beneficial effects of this application are as follows: By using a reflector (reflective surface), some light is reflected and directed towards the second light-emitting area of ​​the first light guide component. This reflects and illuminates the second light-emitting area, widening the accompanying illumination area of ​​the first light guide component and preventing a visual void caused by a dark second light-emitting area. Both the first and second light-emitting areas are illuminated, which helps improve the overall harmony and aesthetics of the headlight design. When the low beam is on, the accompanying illumination in the high beam area also increases the low beam's illumination range. Furthermore, the overall illuminance is higher when the low beam is on, making the vehicle more visible at night or in low-light conditions, increasing its visibility to other road users and reducing the risk of traffic accidents.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] The optical module, headlights, and vehicle of this application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] In existing technologies, traditional high and low beam headlights are separate modules. When the low beam is in operation, the high beam module area is dark, creating a visual void. This makes the overall headlight design lack coordination and aesthetics, and the low beam lighting effect is poor.

[0030] To address the aforementioned technical problems, this application provides an optical module including a first light guide component, a companion light source, and a reflector. The first light guide component has a first light-emitting region and a second light-emitting region. The companion light source is configured to illuminate one of the first light-emitting region and the second light-emitting region. The reflector is disposed between the first light guide component and the companion light source, and the reflector has a reflective surface on its side facing the companion light source. The reflective surface is configured to receive a portion of the light provided by the companion light source and reflect the light to the other of the first light-emitting region and the second light-emitting region. The second light-emitting region is located on the side of the first light-emitting region away from the reflective surface. This will be described in detail below.

[0031] See Figure 1 The optical module includes a first light guide component 10, an accompanying light source 20, and a reflector. The first light guide component 10 has a first light emitting region 11 and a second light emitting region 12. The accompanying light source 20 is configured to illuminate one of the first light emitting region 11 and the second light emitting region 12. The reflector is disposed between the first light guide component 10 and the accompanying light source 20. The reflector has a reflective surface 30 on the side of the reflector facing the accompanying light source 20. The reflective surface 30 is configured to receive part of the light provided by the accompanying light source 20 and reflect the light to the other of the first light emitting region 11 and the second light emitting region 12. The second light emitting region 12 is disposed on the side of the first light emitting region 11 away from the reflective surface 30.

[0032] For ease of explanation, in the following embodiments, the light reflected by the reflective surface 30 is directed toward the second light-emitting region 12 for the accompanying illumination of the second light-emitting region 12.

[0033] In this embodiment, when the accompanying light source 20 is lit, the first light-emitting area 11 is illuminated; through the setting of the reflector (reflective surface 30), some light will be reflected by the reflective surface 30 and then directed to the second light-emitting area 12 of the first light guide component 10, reflecting some of the light emitted by the accompanying light source 20 and illuminating the second light-emitting area 12, thus widening the accompanying illumination area of ​​the first light guide component 10 and avoiding visual emptiness caused by the second light-emitting area 12 being dark. Both the first light-emitting area 11 and the second light-emitting area 12 are illuminated, which helps to improve the overall coordination and aesthetics of the headlight design. When the low beam is on, the high beam area (i.e., the first light guide component 10) has accompanying light (including light from the accompanying light source 20 directed to the first light-emitting area 11, and light reflected by the reflective surface 30 and directed to the second light-emitting area 12, the same below), which increases the low beam illumination range. Moreover, the overall illuminance value is higher when the low beam is on, which makes the vehicle more visible at night or in low light conditions, making it easier for other road users to notice it, thereby reducing the risk of traffic accidents.

[0034] It should be noted that the intensity of the accompanying light is weaker than that of the high beam, thus avoiding glare for road users when the high beam is directly turned on. In practical applications, the first light guide component 10 is a high beam lens. Through the setting of the reflective surface 30, the first light guide component 10 has accompanying light in a large area (the first light-emitting area 11 and the second light-emitting area 12), avoiding the visual void caused by the high beam area being dark or having a small illuminated area when the low beam is on. This improves the overall coordination and aesthetics of the headlight design and increases the low beam illumination range.

[0035] It is worth mentioning that the first light-emitting region 11 and the second light-emitting region 12 can be set apart, or they can overlap or border each other; no specific limitation is made here.

[0036] In some embodiments, the angle between the reflective surface 30 and the horizontal plane is β, which satisfies: 0°≤β≤20°, such as 0°, 10°, 20°, etc.

[0037] When the value of β is less than 0°, the light rays reflected by the reflecting surface 30 (denoted as λ, and the horizontal surface as η) (accompanied by the lit light rays) will overlap with the light rays of the first light-emitting area 11, and cannot properly illuminate the second light-emitting area 12. The second light-emitting area 12 has less light, appears visually hollow, and is not conducive to increasing the illumination range, which is detrimental to driving safety.

[0038] When the value of β is greater than 20°, the light reflected by the reflective surface 30 will be directed to an area outside the first light guide component 10 and will not be able to illuminate the second light-emitting area 12, resulting in a waste of light.

[0039] In summary, by adjusting the value of β, the light reflected by the reflective surface 30 can be directed well to the second light-emitting area 12 of the first light guide component 10, which widens the illumination range of the high beam area when the low beam is on, increases the illumination range of the low beam, and the overall illuminance value is higher when the low beam is on, making the vehicle more visible at night or in low light conditions, making it easier for other road users to notice it, thereby reducing the risk of traffic accidents.

[0040] It should be noted that, as Figure 1 As shown, in some embodiments, the first light-emitting region 11 of the first light-guiding component 10 is located below the second light-emitting region 12. When the value of β is less than 0°, the reflective surface 30 exhibits an inclined trend as shown by surface λ′, which also falls within the protection scope of this application. In some embodiments, such as Figure 2 As shown, the first light-emitting region 11 of the first light-guiding component 10 is located above the second light-emitting region 12. When the value of β is less than 0°, the reflective surface 30 is shaped as shown by surface λ″.

[0041] In some embodiments, the optical module further includes a reflector 40, wherein light rays from the light source 20 that are directed toward the reflector 40 are reflected by the reflector 40 and directed toward the first light-emitting region 11, and light rays from the light source 20 that are directed toward the reflective surface 30 are reflected by the reflective surface 30 and directed toward the second light-emitting region 12.

[0042] In this embodiment, the light from the accompanying light source 20 that does not reach the reflector 40 is fully utilized to form part of the accompanying illumination, thus widening the range of the accompanying illumination and increasing the illumination range and illuminance value when the low beam is on. In traditional optical modules, the light from the accompanying light source 20 that does not reach the reflector 40 is often wasted, and light leakage must be prevented. In this embodiment, the wasted light is reused, widening the range of the accompanying illumination and improving the illumination range and illuminance value when the low beam is on, making the vehicle more visible at night or in low light conditions. At the same time, there is no need to arrange a light-shielding structure to prevent light leakage, simplifying the manufacturing process and reducing production costs.

[0043] See Figure 3 In some embodiments, the optical module further includes a second light guide component 50, which is disposed between the accompanying light source 20 and the first light guide component 10. The accompanying light source 20 includes a first LED 21 and a second LED 22. The light emitted by the first LED 21 is adjusted by the second light guide component 50, and part of it is directed toward the first light-emitting area 11 of the first light guide component 10, part of it is directed toward the reflecting surface 30, and then reflected by the reflecting surface 30 toward the second light-emitting area 12. The light emitted by the second LED 22 is adjusted by the second light guide component 50 to be directed toward the reflecting surface 30, and then reflected by the reflecting surface 30 toward the second light-emitting area 12.

[0044] By setting the first light guide component 10 and the second light guide component 50, the light can be adjusted according to the lighting requirements, such as diffusing the light to increase the illumination range, and not limited to this.

[0045] After the light emitted by the first LED 21 is processed by the second light guide component 50, part of the light is directed towards the first light-emitting area 11 of the first light guide component 10, and part of the light is directed towards the reflective surface 30. After being reflected by the reflective surface 30, the light is directed towards the second light-emitting area 12 of the first light guide component 10. In this embodiment, a second LED 22 is also provided. After the first LED 21 is lit, the second LED 22 is lit. The light emitted by the second LED 22 is processed by the second light guide component 50 and directed towards the reflective surface 30. After being reflected by the reflective surface 30, the light is directed towards the second light-emitting area 12 of the first light guide component 10. The light from the second LED 22 mixes with the light from the first LED 21 directed towards the second light-emitting area 12, increasing the luminous flux of the accompanying light in the second light-emitting area 12 and improving the brightness. This makes the vehicle more visible at night or in low light conditions, making it easier for other road users to notice it, thereby reducing the risk of traffic accidents.

[0046] It should be noted that the amount of light emitted by the first LED 21 to the second light-emitting area 12 is relatively small. The second LED 22 supplements the illumination, thereby increasing the brightness of the second light-emitting area 12 and improving the consistency of the overall brightness (the brightness accompanying the illumination). Of course, in some embodiments, when the amount of light emitted by the first LED 21 to the second light-emitting area 12 is sufficient, the second LED 22 may not be necessary. The light can also be adjusted by adjusting the way the second light guide component 50 processes the light, and this is not the only option.

[0047] In some embodiments, the first LED 21 and the second LED 22 are disposed on the same printed circuit board.

[0048] The first LED 21 and the second LED 22 share a single printed circuit board, which reduces production costs and eliminates the need for an additional printed circuit board, thus avoiding the occupation of internal space.

[0049] In some embodiments, the reflective surface 30 is provided with a uniform texture.

[0050] By uniformizing the texture, the light pattern accompanying the illumination can be more uniform, avoiding bright spots. The structure is simple and the display effect is good.

[0051] In some embodiments, the optical module further includes a bracket, and the first light guide component 10 is disposed on the bracket; the bracket is provided with the reflective surface 30.

[0052] The bracket is equipped with the reflective surface 30, that is, the reflective element and the bracket are designed as one piece, that is, the reflective element is part of the bracket, which eliminates the need for additional structures, simplifies the structure and reduces production costs; and avoids the installation operation of the reflective surface 30 (reflective element), which helps to ensure the accuracy of the relative positions between the first light guide component 10, the reflective surface 30 and the accompanying light source 20, and is conducive to improving the lighting effect.

[0053] In some embodiments, the first light guide component 10 and the accompanying light source 20 are disposed on the same side of the reflective surface 30, which is beneficial for the internal structure arrangement of the headlight, and the reflective surface 30 can also block some light from shining into the area below the reflective surface 30. Figure 1 (View angle) to avoid interference with other optical modules in the headlights.

[0054] On the other hand, this application also relates to a vehicle light, including any of the aforementioned optical modules.

[0055] On the other hand, this application also relates to a vehicle including the aforementioned headlights.

[0056] The technical solution provided in this application aims to, through the setting of the reflector (reflective surface 30), allow some light to be reflected by the reflective surface 30 and directed towards the second light-emitting area 12 of the first light guide component 10. This reflects and illuminates part of the light emitted by the accompanying light source 20, widening the accompanying illumination area of ​​the first light guide component 10 and preventing visual voids caused by the second light-emitting area 12 being dark. Both the first light-emitting area 11 and the second light-emitting area 12 are illuminated, which helps to improve the overall coordination and aesthetics of the headlight design. When the low beam is on, the high beam area has accompanying illumination, increasing the low beam illumination range. Furthermore, the overall illuminance value is higher when the low beam is on, making the vehicle more visible at night or in low light conditions, and easier for other road users to notice, thereby reducing the risk of traffic accidents.
