Description

Technical Field

[0001] This application relates to the field of concentrator technology, and more specifically to a concentrator assembly and optical module. Background Technology

[0002] Currently, most automotive headlight combination lights use integrated high and low beam modules. However, these modules have significant drawbacks, such as limited functionality and inconvenient switching between high and low beams. Combination headlights using matrix-type light modules offer more diverse functions and improve nighttime driving safety, making them a growing trend in automotive lighting development.

[0003] For combination headlights equipped with matrix LED light-emitting modules, the light pattern of multiple light-emitting blocks replaces the traditional single-area high beam pattern. The emitted light pattern has requirements for uniformity, illumination range, integration with low beam, and regulatory compliance. The overall matrix LED light pattern is composed of multiple pixel units, and the brightness of each pixel unit is intelligently controlled by the in-vehicle advanced driver assistance system (ADAS system), thereby achieving multiple functions such as light bending, anti-glare, and light pattern expansion.

[0004] In current matrix-type light-emitting modules, when using dual-row condensers as primary optical elements, both rows of condensers are usually designed as symmetrical structures. This design wastes resources for the upper row of condensers, meaning that the outermost condenser cup is not very effective while meeting regulatory requirements. As for the lower row of condensers, the outermost condenser cup cannot be designed to be very large because space must be left for the upper row of condensers. This means that the angle of the light emitted from the condenser cup cannot be very large, resulting in insufficient outer width of the light pattern and difficulty in clearly illuminating objects on the outer edges. Summary of the Invention

[0005] The purpose of this application is to overcome the problem of insufficient outer beam width in the existing technology, and to provide a concentrator assembly and optical module that adopts an asymmetrical structural design, which has the advantage of improving the outer beam width, thereby increasing the beam illumination range, so that objects on the outer side can be clearly illuminated, providing a wider driving field of vision and ensuring driving safety.

[0006] To achieve the above objectives, in a first aspect, this application provides a concentrator assembly, including a first concentrator and a second concentrator disposed vertically opposite each other;

[0007] The second condenser includes a second condensing light-inlet section, a second condensing light-transmitting section, and a second condensing light-outlet section arranged sequentially from back to front along the light-emitting direction. The second condensing light-inlet section includes an inner light-inlet section and an outer light-inlet section. The second condensing light-transmitting section includes an inner light-transmitting section and an outer light-transmitting section. The second condensing light-outlet section includes an inner light-outlet section and an outer light-outlet section. At least one set of the inner light-inlet section, the inner light-transmitting section, and the inner light-outlet section are arranged accordingly. At least one set of the outer light-inlet section, the outer light-transmitting section, and the outer light-outlet section are arranged accordingly. The light-emitting surfaces of the inner light-outlet section and the outer light-outlet section are connected to form a curved surface.

[0008] From a reference perspective, the upper boundary of the light-emitting surface of the outer light-emitting part is higher than the lower boundary of the light-emitting surface of the first condenser, and the upper boundary of the light-emitting surface of the inner light-emitting part can be aligned with the lower boundary of the light-emitting surface of the first condenser.

[0009] In some embodiments, from a reference viewing angle, the upper boundary of the light-emitting surface of the light-emitting part is at the same height as the upper boundary of the light-emitting surface of the first condenser.

[0010] In some embodiments, at a reference viewing angle, the lower boundary of the light-emitting surface of the outer light-emitting part is at the same height as the lower boundary of the light-emitting surface of the inner light-emitting part.

[0011] In some embodiments, the left and right sides of the external light-transmitting portion gradually slope outward from the end connected to the external light-injecting portion to the end connected to the external light-out portion.

[0012] In some embodiments, the left and right sides of the inner light-transmitting portion gradually extend outward from the end connected to the inner light-inlet portion to the end connected to the inner light-out portion, and the inclination angle of the left and right sides of the inner light-transmitting portion is smaller than the inclination angle of the left and right sides of the outer light-transmitting portion.

[0013] In some embodiments, from a reference viewing angle, the upper and lower sides of the external light-transmitting portion gradually tilt outward from the end connected to the external light-increasing portion to the end connected to the external light-exiting portion.

[0014] The upper and lower sides of the inner light-transmitting part gradually slope outward from the end connected to the inner light-entry part to the end connected to the inner light-exit part.

[0015] In some embodiments, the first condenser includes a first condensing light-inlet section, a first condensing light-transmitting section, and a first condensing light-outlet section. At least two sets of the first condensing light-inlet section, the first condensing light-transmitting section, and the first condensing light-outlet section are provided. The left and right sides of the first condensing light-transmitting section gradually extend outward from the end connected to the first condensing light-inlet section to the end connected to the first condensing light-outlet section.

[0016] In some embodiments, the area of ​​the light-emitting surface of the first light-emitting portion corresponding to the outermost first light-concentrating light-transmitting portion is greater than the area of ​​the light-emitting surface of the first light-concentrating light-emitting portion corresponding to the other first light-concentrating light-transmitting portions.

[0017] In some embodiments, the system further includes a first pressure plate, a second pressure plate, and a concentrator bracket connected between the first pressure plate and the second pressure plate, wherein the first concentrator is disposed between the first pressure plate and the concentrator bracket, and the second concentrator is disposed between the second pressure plate and the concentrator bracket.

[0018] In some embodiments, a fixing boss is provided on the side of the first condenser, and a fixing slot is provided on the condenser bracket for the fixing boss to be inserted.

[0019] In some embodiments, two adjacent second light-concentrating and light-transmitting portions are connected by a second connecting portion.

[0020] In some embodiments, the second connecting portion divides the gap between two adjacent second light-concentrating and light-transmitting portions into a first gap and a second gap, and the light-concentrating bracket is provided with a first limiting protrusion embedded in the first gap and a second limiting protrusion embedded in the second gap.

[0021] Secondly, this application provides an optical module including the aforementioned condenser assembly.

[0022] Through the above technical solution, the condenser assembly provided in this application includes a first condenser and a second condenser arranged vertically opposite each other; the second condenser includes a second condensing light-inlet section, a second condensing light-transmitting section, and a second condensing light-outlet section arranged sequentially from back to front along the light-emitting direction. The second condensing light-inlet section includes an inner light-inlet section and an outer light-inlet section, the second condensing light-transmitting section includes an inner light-transmitting section and an outer light-transmitting section, and the second condensing light-outlet section includes an inner light-outlet section and an outer light-outlet section.

The light-emitting surfaces of the inner light-outlet section and the outer light-outlet section are connected to form a curved surface. At a reference viewing angle, the upper boundary of the light-emitting surface of the outer light-outlet section is higher than the lower boundary of the light-emitting surface of the first condenser, and the upper boundary of the light-emitting surface of the inner light-outlet section can fit with the lower boundary of the light-emitting surface of the first condenser, so that the first condenser and the second condenser are asymmetrically arranged. Specifically, the first and second condensers are offset in the left-right direction, providing more space for the outer light-emitting section, thus increasing its light-emitting surface and improving the outer broadening of the light pattern formed by the second condenser. This application employs an asymmetrical structural design for the second condenser and the condenser assembly as a whole, increasing the space available on the outer side and enlarging the light-emitting surface of the outer light-emitting section. This allows for an increase in the illumination range of the second condenser and a greater outer broadening of the light pattern, thereby solving the problem of insufficient outer broadening of the light pattern in existing condenser structures.

[0051] Reference Figures 1-4 In a first aspect, this application provides a concentrator assembly, including a first concentrator 2 and a second concentrator 3 disposed opposite to each other;

[0052] The second condenser includes a second condensing light-inlet section, a second condensing light-transmitting section, and a second condensing light-outlet section arranged sequentially from back to front along the light-emitting direction. The second condensing light-inlet section includes an inner light-inlet section and an outer light-inlet section. The second condensing light-transmitting section includes an inner light-transmitting section and an outer light-transmitting section. The second condensing light-outlet section includes an inner light-outlet section and an outer light-outlet section. At least one set of the inner light-inlet section, the inner light-transmitting section, and the inner light-outlet section are arranged accordingly. At least one set of the outer light-inlet section, the outer light-transmitting section, and the outer light-outlet section are arranged accordingly. The light-emitting surfaces of the inner light-outlet section and the outer light-outlet section are connected to form a curved surface.

[0053] From a reference perspective, the upper boundary of the light-emitting surface of the outer light-emitting part is higher than the lower boundary of the light-emitting surface of the first condenser, and the upper boundary of the light-emitting surface of the inner light-emitting part can be aligned with the lower boundary of the light-emitting surface of the first condenser.

[0054] This application provides a concentrator assembly, including a first concentrator 2 and a second concentrator 3 arranged vertically opposite each other. The light pattern formed by the first concentrator 2 can be used as a component of the near beam pattern. The second concentrator 3 has an asymmetrical structure, and the light pattern formed by the second concentrator 3 can be used as a component of the high beam pattern. The concentrator assembly is asymmetrically arranged, that is, the first concentrator 2 and the second concentrator 3 are offset in the left-right direction, providing more space for the outer light-emitting section 36, increasing its light-emitting surface, thereby widening the outer edge of the light pattern of the emitted light formed by the second concentrator 3.

[0055] The second condenser 3 includes a second condensing light-inlet section, a second condensing light-transmitting section, and a second condensing light-outlet section arranged sequentially along the light-outlet direction. The second condensing light-inlet section includes an inner light-inlet section 31 and an outer light-inlet section 34. The second condensing light-transmitting section includes an inner light-transmitting section 32 and an outer light-transmitting section 35. The second condensing light-outlet section includes an inner light-outlet section 33 and an outer light-outlet section 36. At least one set of outer light-inlet section 34, outer light-transmitting section 35, and outer light-outlet section 36 are provided. Multiple sets of inner light-inlet section 31, inner light-transmitting section 32, and inner light-outlet section 33 are provided. Multiple sets of inner light-transmitting section 32 extend in the front-back direction and are arranged at intervals in the left-right direction. The inner light-inlet section 31 is the collection of the end faces of the inner light-transmitting section 32 that are away from the inner light-outlet section 33.

[0056] The external light-inlet section 34, the external light-transmitting section 35, and the external light-outlet section 36 are disposed outside the internal light-inlet section 31, the internal light-transmitting section 32, and the internal light-outlet section 33. The internal light-outlet section 33 and the external light-outlet section 36 are connected to each other, and the light-outlet surfaces of the multiple internal light-outlet sections 33 and the light-outlet surfaces of the external light-outlet sections 36 are connected to form a curved surface.

[0057] Combination Figure 5 With the viewing angle directly facing the light-emitting surface of the light-emitting assembly located at the left headlight of the vehicle as the reference viewing angle, under the reference viewing angle, the upper boundary of the light-emitting surface of the outer light-emitting part 36 is higher than the lower boundary of the light-emitting surface of the first light-emitting part 2, and the upper boundary of the light-emitting surface of the inner light-emitting part 33 is in contact with the lower boundary of the light-emitting surface of the first light-emitting part 2.

[0058] From a reference perspective, the light-emitting surface of the first concentrator 2 is narrow in the vertical direction, with its upper and lower boundaries flush and its overall height consistent. It exhibits overall left-right symmetry, and its light pattern is also relatively symmetrical about the center. Figure 7 As shown; the light-emitting surface of the second concentrator 3 is wide in the vertical direction, and the lengths on both sides of the center line are of different lengths, with one side longer than the other. The corresponding light pattern is wider on the outside and narrower on the inside, as shown. Figure 10 As shown.

[0059] Combination Figure 11 The light pattern formed by the light-emitting surface of the light-emitting section 36 is located on the outer side of the light distribution screen. That is, when applied to high beams, it enhances the outer widening of the high beam pattern, and then combines with... Figure 10 , Figure 10 The combined light pattern formed by the second condenser 3 indicates that the light pattern formed by the light-emitting surface of the inner light-emitting section 33 is located in the center, providing the center brightness of the high beam pattern when applied to high beams. Taking the left headlight of a vehicle as an example, the combined light pattern formed by the second condenser 3 has an inner angle of 7.5° and an outer angle of 23° on the H-axis of the light distribution screen. The angle of the light pattern corresponding to the outer light-emitting section 36 is between -8° and -23° on the H-axis. Thanks to the asymmetrical design of the second condenser 3, the outer width of the light pattern can be increased. The second condenser 3 of the left headlight and the second condenser 3 of the right headlight are symmetrical, and a wider light pattern can be formed after combination.

[0060] The condenser assembly provided in this application, at a reference viewing angle, allows the upper boundary of the light-emitting surface of the light-emitting part 36 to be aligned with the lower boundary of the light-emitting surface of the first condenser, enabling the upper boundary of the light-emitting surface of the light-emitting part 33 to fit snugly against the lower boundary of the light-emitting surface of the first condenser. This results in a larger illumination range on the outer side of the second condenser 3, increasing the outer broadening of the light pattern formed by the second condenser 3. This application employs an asymmetrical structural design for the second condenser 3 and the condenser assembly as a whole, increasing the space available for the outer side and enlarging the light-emitting surface of the light-emitting part 36. This increases the illumination range of the second condenser 3 and the outer broadening of the light pattern, thereby solving the problem of insufficient outer broadening of the light pattern formed by condensers in the prior art.

[0061] Reference Figure 5 and Figure 6 In some embodiments, at a reference viewing angle, the upper boundary of the light-emitting surface of the light-emitting section 36 is at the same height as the upper boundary of the light-emitting surface of the first condenser 2. Accordingly, combined with Figures 10-12 The lower boundary of the light pattern formed by the outgoing light-emitting section 36 is consistent with the lower boundary of the light pattern formed by the first condenser 2, thereby maintaining the integrity and uniformity of the light pattern. Furthermore, the lower boundary of the light-emitting surface of the outgoing light-emitting section 36 is at the same height as the lower boundary of the light-emitting surface of the inner light-emitting section 33, thereby maintaining the integrity and uniformity of the light pattern.

[0062] Reference Figures 4-6 In some embodiments, from a reference viewing angle, the upper boundary of the inner light-emitting portion 33 can be aligned with the lower boundary of the light-emitting surface of the first light-concentrator 2.

[0063] This ensures a natural transition between the light pattern formed by the first concentrator 2 and the light pattern formed by the second concentrator 3.

[0064] Reference Figures 4-6In some embodiments, the left and right sides of the external light-transmitting part 35 gradually tilt outward from the end connected to the external light-inlet part 34 to the end connected to the external light-outlet part 36, thereby increasing the left and right width of the light-outlet surface of the external light-outlet part 36, so that the light pattern formed by the light-outlet surface of the external light-outlet part 36 has a larger left and right width.

[0065] Reference Figures 4-6 In some embodiments, the left and right sides of the inner light-transmitting part 32 gradually extend outward from the end connected to the inner light-entry part 31 to the end connected to the inner light-exit part 33, and the tilt angle of the left and right sides of the inner light-transmitting part 32 is smaller than the tilt angle of the left and right sides of the outer light-transmitting part 35.

[0066] In some embodiments, the left and right sides of the outer light-transmitting section 35 gradually slope outward from the end connected to the outer light-inlet section 34 to the end connected to the outer light-outlet section 36, and the left and right sides of the inner light-transmitting section 32 gradually extend outward from the end connected to the inner light-inlet section 31 to the end connected to the inner light-outlet section 33, thereby improving the broadening of the light pattern formed by the second light-concentrator 3.

[0067] Reference Figure 5 and Figure 6 In some embodiments, from a reference viewing angle, the upper and lower sides of the external light-transmitting portion 35 gradually tilt outward from the end connected to the external light-incident portion 34 to the end connected to the external light-exiting portion 36.

[0068] The upper and lower sides of the inner light-transmitting section 32 gradually slope outward from the end connected to the inner light-entry section 31 to the end connected to the inner light-exit section 33.

[0069] In some embodiments, from a reference viewing angle, the upper and lower sides of the outer light-transmitting section 35 gradually slope outward from the end connected to the outer light-incident section 34 to the end connected to the outer light-emitting section 36, meaning the area of ​​the light-emitting surface of the outer light-emitting section 36 is larger than the area of ​​the light-incident surface of the outer light-incident section 34; the upper and lower sides of the inner light-transmitting section 32 gradually slope outward from the end connected to the inner light-incident section 31 to the end connected to the inner light-emitting section 33, meaning the area of ​​the light-emitting surface of the inner light-emitting section 33 is larger than the area of ​​the light-incident surface of the inner light-incident section 31, so that the light pattern formed by the second condenser 3 has sufficient vertical broadening to meet regulatory requirements. Furthermore, the area of ​​the light-emitting surface of a single outer light-emitting section 36 is larger than the area of ​​the light-emitting surface of a single inner light-emitting section 33, thereby improving the broadening of the outer light pattern.

[0070] Reference Figure 3 and Figure 5In some embodiments, the first light condenser 2 includes a first light-injecting part 21, a first light-transmitting part 22, and a first light-exiting part 23. At least two sets of the first light-injecting part 21, the first light-transmitting part 22, and the first light-exiting part 23 are provided. The left and right sides of the first light-transmitting part 22 gradually extend outward from the end connected to the first light-injecting part 21 to the end connected to the first light-exiting part 23.

[0071] In some embodiments, the first condenser 2 includes a first condensing light-incident section 21, a first condensing light-transmitting section 22, and a first condensing light-exiting section 23. Multiple sets of the first condensing light-incident section 21, the first condensing light-transmitting section 22, and the first condensing light-exiting section 23 are arranged along a left-right direction. The light-emitting surfaces of the multiple first condensing light-exiting sections 23 are connected to form a curved surface, and the multiple first condensing light-transmitting sections 22 are spaced apart from each other. The first condensing light-incident section 21 faces the light source and is located at the end of the first condensing light-transmitting section 22 away from the first condensing light-exiting section 23.

[0072] The left and right sides of the first light-concentrating light-transmitting part 22 gradually extend outward from the end connected to the first light-concentrating light-inlet part 21 to the end connected to the first light-concentrating light-outlet part 23.

[0073] Combination Figures 7-9 In low beam mode, the first condenser 2 can achieve dynamic turning during low beam. By turning the LED, which serves as the light source, on and off, different light rays are emitted through different first condenser light-emitting sections 23, which can present different low beam patterns and achieve dynamic cornering lighting.

[0074] Reference Figure 3 In some embodiments, the area of ​​the light-emitting surface of the first light-emitting part 23 corresponding to the outermost first light-concentrating light-transmitting part 22 is greater than the area of ​​the light-emitting surface of the first light-concentrating light-emitting part 23 corresponding to the other first light-concentrating light-transmitting parts 22.

[0075] In some embodiments, the area of ​​the light-emitting surface of the first light-emitting section 23 corresponding to the outermost first light-concentrating light-transmitting section 22 is larger than the area of ​​the light-emitting surface of the first light-concentrating light-emitting section 23 corresponding to the other first light-concentrating light-transmitting sections 22. The light pattern formed by the light-emitting surface of the outermost first light-concentrating light-emitting section 23 can have an outer angle of up to 12° on the H-axis of the light distribution screen, increasing the broadening of the light pattern formed by the first condenser 2. When applied to low beam conditions, this ensures the low beam illumination range, providing the driver with sufficient driving visibility.

[0076] Reference Figure 1 , Figure 13 and Figure 14In some embodiments, the concentrator assembly further includes a first pressure plate 4, a second pressure plate 5, and a concentrator support 1 connected between the first pressure plate 4 and the second pressure plate 5. The first concentrator 2 is disposed between the first pressure plate 4 and the concentrator support 1, and the second concentrator 3 is disposed between the second pressure plate 5 and the concentrator support 1.

[0077] In some embodiments, the condenser bracket 1 includes two opposing uprights and a horizontal partition plate, with the uprights respectively disposed on both sides of the horizontal partition plate, so that the condenser bracket 1 is generally C-shaped. The first condenser 2 is installed on one side of the condenser bracket 1, and the second condenser 3 is installed on the other side of the condenser bracket 1.

[0080] This application uses the same method to fix the second pressure plate 5, the first condenser 2 and the condenser bracket 1, which will not be described again here.

[0081] Reference Figure 2 and Figure 3 In some embodiments, a fixing boss 24 is provided on the side of the first condenser 2, and a fixing slot 11 is provided on the condenser bracket 1 for the fixing boss 24 to be inserted.

[0082] In some embodiments, a fixing boss 24 is provided on one side of the first condenser 2, and a fixing slot 11 is provided on the condenser bracket 1. When the first condenser 2 is installed, the fixing boss 24 is embedded in the fixing slot 11, which plays a role in stabilizing the position of the first condenser 2.

[0083] Reference Figure 4 In some embodiments, two adjacent second light-concentrating and light-transmitting sections are connected by a second connecting section 37.

[0084] Reference Figure 2 and Figure 4 In some embodiments, the second connecting portion 37 divides the gap between two adjacent second light-concentrating portions into a first gap 38 and a second gap 39. The light-concentrating bracket 1 is provided with a first limiting protrusion 12 embedded in the first gap 38 and a second limiting protrusion 13 embedded in the second gap 39.

[0085] In some embodiments, the second condenser 3 is provided with a plurality of second connecting portions 37, and the aforementioned second connecting portions 37 are provided between any two adjacent second condensing light-transmitting portions, with the plurality of second connecting portions 37 located on the same horizontal line. The second connecting portions 37 divide the gap between adjacent second condensing light-transmitting portions into a first gap 38 and a second gap 39. The first gap 38 is located in front of the second connecting portion 37, and the second gap 39 is located behind the second connecting portion 37. The horizontal partition plate of the condenser bracket 1 is provided with a first limiting protrusion 12 and a second limiting protrusion 13 on the side facing the second condenser 3. The first limiting protrusion 12 is embedded in the first gap 38, and the second limiting protrusion 13 is embedded in the second gap 39. The lower surface of the first limiting protrusion 12 is in contact with the upper surface of the second connecting portion 37, and the upper surface of the second limiting protrusion 13 is in contact with the lower surface of the second connecting portion 37.

[0087] In a preferred embodiment of the condenser assembly disclosed in this application, a first condenser 2 and a second condenser 3 are arranged vertically opposite each other. The light pattern formed by the first condenser 2 can be used as a low beam or as a component of a low beam, and can be combined with other low beam components to form a complete low beam. The second condenser 3 has an asymmetrical structure, and the light pattern formed by the second condenser 3 can be used as a high beam or as a component of a high beam, realizing the Adaptive Driving Beam (ADB) function. The first condenser 2 and the second condenser 3 are asymmetrically arranged, that is, the first condenser 2 and the second condenser 3 are offset in the left-right direction, providing more space for the outer light-emitting part 36, increasing its light-emitting surface, thereby improving the outer widening of the light pattern formed by the second condenser 3.

[0088] The condenser assembly provided in this application, at a reference viewing angle, has an upper boundary of the light-emitting surface of the light-emitting section 36 that is higher than the lower boundary of the light-emitting surface of the first condenser, resulting in a larger illumination range on the outer side of the second condenser 3 and increasing the outer broadening of the light pattern formed by the second condenser 3. This application employs an asymmetrical structural design for the second condenser 3 and the condenser assembly as a whole, increasing the space available for the outer side and enlarging the light-emitting surface of the light-emitting section 36 to increase the illumination range of the second condenser 3 and increase the outer broadening of the light pattern, thereby solving the problem of insufficient outer broadening of the light pattern in existing condenser structures.

[0089] Reference Figure 19 Secondly, this application provides an optical module including the aforementioned condenser assembly.
