Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, specifically to a dual-function module and lighting system, and more particularly to a dual-function module that combines automotive high and low beam functions. Background Technology

[0002] Existing headlight modules are generally large-aperture modules, which typically use telephoto lenses. In this case, the optical efficiency is relatively low. Existing headlight modules generally cannot achieve small apertures. Even if they can, they are small apertures for individual functions, such as separate low beams and separate high beams. They cannot achieve integrated high and low beam ultra-narrow aperture modules. The optical aperture of an ultra-narrow aperture module is closely related to its optical efficiency. The smaller the aperture, the more difficult it is to improve the optical efficiency.

[0003] Because the low beam cutoff line light pattern in the headlight module requires a separate shutter component, and the cutoff line area needs a separate structure for independent lighting, designing the headlight module with a small opening would make the design more complicated, increase production costs, make installation and position deviations uncontrollable, and also present space problems.

[0004] While some modules have reduced the opening size, they still have shortcomings in terms of light pattern and light control. For example, the low beam pattern is prone to stray light and insufficient light efficiency. Existing technologies use reflective solutions, but reflective solutions have problems when achieving ultra-narrow openings. It is difficult to arrange the light source when there are large differences in the customer's shape. On the basis of narrow opening, it is necessary to achieve excellent light pattern and integrate the low beam and high beam into one. The compatibility of the three is something that existing technologies cannot achieve. Summary of the Invention

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention integrates high and low beam functions into the same module by setting a second optical component, which includes a high beam part and a low beam part, thereby realizing an ultra-narrow aperture module;

[0025] 2. By setting the high beam and low beam sections as a common optical element, the present invention integrates the high beam and low beam modules into a single module, which greatly reduces the overall cost compared to separate high beam and low beam modules.

[0026] 3. By setting the near beam cutoff line structure on the near beam section, the present invention can eliminate the need for the light shield of the traditional module, further reducing the overall cost of the module;

At the same time, the outer surface of the lens can also be freely modified to a greater extent according to the shape requirements, thereby better meeting the needs of differentiated shapes in the market.

[0059] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0060] Example 1:

[0061] like Figures 1-21 As shown, this embodiment provides a dual-function module, including: a first optical component 101, a clamping component 102, a second optical component 103, and a light source assembly. The light source assembly, the second optical component 103, and the first optical component 101 are sequentially arranged on the clamping component 102 along the light emission direction. The second optical component 103 includes a high beam portion 1031 and a low beam portion 1032, which are arranged sequentially along a first direction. The light source assembly includes a high beam light source component 105 and a low beam light source component 104. The high beam light source component 105 is arranged corresponding to the high beam portion 1031, and the low beam light source component 104 is arranged corresponding to the low beam portion 1032. The light emitted by the high beam light source component 105 passes sequentially through the high beam portion 1031 and the first optical component 101, and the light emitted by the low beam light source component 104 passes sequentially through the low beam portion 1032 and the first optical component 101.

[0062] The high beam light source component 105 and the low beam light source component 104 are mounted on the same flexible circuit board or on two separate PCBs. The flexible circuit board or the PCB is mounted on the heat dissipation component 106. In this embodiment, a PCB is used.

[0063] The second optical component 103 further includes a high beam collimation section 1033 and a low beam collimation section 1034. The high beam collimation section 1033 is disposed at the light-incident end of the high beam section 1031, the low beam collimation section 1034 is disposed at the light-incident end of the low beam section 1032, the high beam light source component 105 is disposed at the light-incident end of the high beam collimation section 1033, and the low beam light source component 104 is disposed at the light-incident end of the low beam collimation section 1034.

[0064] The high beam section 1031 includes multiple high beam cavity structures, the high beam collimation section 1033 includes multiple high beam collimation structures, and the high beam light source component 105 includes multiple high beam light sources. Each high beam cavity structure has at least one high beam collimation structure at its light-incident end, and each high beam collimation structure has at least one high beam light source at its light-incident end.

[0065] The low beam section 1032 includes multiple low beam cavity structures, the low beam collimation section 1034 includes multiple low beam collimation structures, and the low beam light source component 104 includes multiple low beam light sources. Each low beam cavity structure has at least one low beam collimation structure at its light-incident end, and each low beam collimation structure has at least one low beam light source at its light-incident end.

[0066] The low beam section 1032 has a notch structure, on which a cutoff line working surface 10321 is formed, and a stepped cutoff line structure is provided on the cutoff line working surface 10321. The low beam collimation section 1034 has a cutoff plane 10341, which is located near the notch structure.

[0067] Along the light emission direction, the light emission end face of the low beam section 1032 is located in front of the light emission end face of the high beam section 1031. Along the light emission direction, the low beam collimating section 1034 is located in front of the high beam collimating section 1033.

[0068] The PCB board is fixedly mounted on the heat dissipation component 106. The PCB board is fixed to the heat dissipation component 106 by screws, and thermal adhesive is applied between the PCB board and the heat dissipation component 106.

[0069] In this example, the clamping component 102 is a housing, and a positioning post is provided inside the clamping component 102. The second optical component 103 is positioned by the positioning post.

[0070] The second optical component 103 is fixedly connected to the heat dissipation component 106 via a snap-fit ​​structure. The first optical component 101 is fixedly connected to the clamping component 102 via a snap-fit ​​structure. The clamping component 102 is fixedly connected to the heat dissipation component 106 via screws.

[0071] In this embodiment, the individual shutter component can be integrated with other components into a single unit. This projection-based solution allows for adjustments to the light source position to meet even significant differences in the customer's desired shape, thus satisfying the design requirements.

[0072] This embodiment also provides a vehicle lighting system, including the aforementioned dual-function module.

[0073] Example 2:

[0074] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0075] This embodiment provides a dual-function module that combines the high and low beam functions of a car, which includes: a first optical component 101, a clamping component 102, a second optical component 103, a low beam light source component 104, a high beam light source component 105, and a heat dissipation component 106.

[0076] The low beam light source component 104 and the high beam light source component 105 are fixed to the heat dissipation component 106 by screws or other fixing structures. A heat dissipation adhesive with heat dissipation effect is applied between the low beam light source component 104, the high beam light source component 105 and the heat dissipation component 106, so that the working heat of the light source can be effectively dissipated through the heat dissipation component 106.

[0077] The second optical component 103 is positioned with the heat dissipation component 106 via a positioning post, and then fixed to the heat dissipation component 106 via a fastener or other fixing structure. The first optical component 101 is fixed to the clamping component 102 via a fastener or other fixing structure, and the clamping component 102 is fixed to the heat dissipation component 106 via screws or other fixing structures.

[0078] The second optical component 103 includes a high beam portion 1031 and a low beam portion 1032. The high beam portion 1031 and the low beam portion 1032 are arranged horizontally, with the high beam portion 1031 located on one side and the low beam portion 1032 located on the other side next to it.

[0079] like Figure 2 As shown, the front end face of the low beam portion 1032 and the front end face of the high beam portion 1031 are approximately (in the depth direction) Figure 2 (In the vertical direction, the front surface of the low beam 1032 may be higher than the front surface of the high beam 1031 in the depth direction. However, the rear surface of the low beam 1032 is higher than the rear surface of the high beam 1031 in the depth direction. That is, the rear surface of the low beam 1032 and the rear surface of the high beam 1031 are not on the same plane and are a certain distance apart.

[0080] The space between the rear end face of the low beam section 1032 and the rear end face of the high beam section 1031 is removed, and there is no material or related transparent structure of the second optical component. Air is used as the medium in this space. The rear end face of the low beam section 1032 and the low beam section 1032 are designed in this way to meet the design requirements of the OEM and to further optimize the design. Because the low beam section 1032 is set up like this, the emission angle of the light after reaching the low beam section 1032 is wider, and the low beam illumination is wider. If the rear end face of the low beam section 1032 is made to be flush with the high beam section 1031, the focal length will be very long, and there will be defects in the widening and light effect.

[0081] In this embodiment, the high beam section 1031 is configured with three structural parts, and the low beam section 1032 is configured with five structural parts.

[0082] like Figure 3 As shown, the second optical component 103 also includes a high beam collimation section 1033 and a low beam collimation section 1034. The high beam collimation section 1033 is disposed on the light-incident end side of the high beam section 1031, and the low beam collimation section 1034 is disposed on the light-incident end side of the low beam section 1032.

[0083] The low beam collimator 1034 is positioned higher on the X-axis of the vehicle coordinate system than the high beam collimator 1033 (i.e., above the vehicle body coordinate system X-axis). Figure 3 (As shown in the vertical direction), the low beam collimator 1034 and the high beam collimator 1033 do not need to be set on the same horizontal plane. The corresponding low beam light source and its PCBA board and the high beam light source and its PCB board are set at the light-incident ends of their respective low beam collimator 1034 and high beam collimator 1033. The low beam collimator 1034 is set higher, that is, closer to the light-emitting side of the low beam section 1032, so that the distance from the low beam collimator to the low beam light-emitting surface along the X direction of the vehicle coordinate system is shorter. This prevents the low beam from having a lot of stray light when hitting the low beam light-emitting surface due to the presence of many large-angle light from the low beam when the distance is too long. The distance between the high beam collimator 1033 and the high beam light-emitting surface can be set more flexibly. Most of the high beam light patterns are relatively parallel light, so there will be no stray light problem caused by the long distance.

[0084] The PCB boards for the low beam and high beam light sources can be set as two separate pieces, arranged vertically; or they can be set as the same piece, using flexible boards or similar materials to achieve vertical arrangement; or they can be the same piece of hardware or flexible boards, arranged on the same horizontal plane. In this case, the collimation head's light-incident end is set to the same horizontal plane. Although the low beam may have stray light problems as a result, these can be improved through collimation structure optimization.

[0085] like Figure 4 As shown, the cutoff line working surface 10321 of the low beam section 1032 is provided on the low beam section 1032, and the rear part of the low beam section 1032 ( Figure 4 The lower part (the lower position of the Z-axis in the vehicle coordinate system) of the aforementioned lower portion is partially removed, and there is no lens structure (no part material); it is empty. A cutoff line working surface 10321 is provided on the upper end face of this removed structure. The cutoff line working surface 10321 of the low beam portion 1032 is located near the lens structure of the exit portion of the low beam portion 1032, such as... Figure 4 The A-frame area shown is used to create the low beam cutoff line, eliminating the need for a separate shutter part in existing technologies. It can be partially aluminum-plated or not aluminum-plated. The A-frame area is the cut-out part, and this surface serves as the shutter surface, mainly the front area of ​​the A-frame area shown in the figure.

[0086] More specifically, such as Figure 5As shown, the cutoff surface 10321 of the low beam section 1032 has at least one plane and a stepped inclined surface that forms a step with the at least one plane. The other end of the inclined surface connects to the next plane. It is stated above that the cutoff surface 10321 of the low beam section 1032 is... Figure 4 That area, more precisely, the surface that functions as the low beam cutoff line is Figure 5 The middle cutoff surface 103211 is the intersecting surface of the cutoff line action surface 10321 and the rear side surface of the near beam emitting part 1032.

[0087] like Figure 6 As shown, in this embodiment, the high beam collimation section 1033 is provided with six collimator structures, and the low beam collimation section 1034 is provided with seven collimator structures.

[0088] like Figure 7 The diagram shows the light path after the LED light is emitted from the second optical component 103. Only one unit is shown. The right side is the high beam light path, where the high beam LED is emitted from the second optical component 103, collimated, and emitted from the high beam emission surface. The left side is the low beam light path, where the low beam LED is emitted from the second optical component 103, collimated, and emitted from the high beam emission surface.

[0089] like Figure 8 and Figure 18 As shown, the cutoff plane 10341 is the surface formed by removing a portion of the near beam collimator 1034, specifically the area within the B-frame. Unlike the high beam collimator 1033, the near beam collimator 1033's collimation structure is not completely enclosed; a portion of the near beam collimator can be designed with a cut-out surface. Based on the complete surface of the near beam collimator 1034, a portion is removed to form the cutoff plane 10341. The cutoff plane 10341 formed on the near beam collimator structure has a focal point relatively far from the shutter.

[0090] Combination Figure 17 The optical path shown explains the reason for setting the cutoff plane 10341: If the cutoff plane 10341 is not set, and the integrity of the near beam collimation section 1034 is preserved, then as follows... Figure 17The C-shaped curved surface shown is the structure of this surface without the cutoff plane 10341. The dashed light path is the light path that would appear without the cutoff plane 10341. The LED emitted light hits the collimating structure and then the C-shaped curved surface. Some of the light is refracted and directly passes through the lower air section to hit the end face 1035 of the second optical component 103 again, entering the second optical component 103. Then it hits the exit surface of the second optical component 103 and arrives at the first optical component 103101. After incident and exit, the final emitted light pattern will have a large angle and is not close to the parallel light emission direction, resulting in stray light problems. Furthermore, the portion of light transmitted through the air mentioned above may be uncontrollable and lost because it has not been transmitted inside the second optical component 103. To ensure that the D-surface is controlled so that most of the exit surfaces do not have large angles and are close together.

[0091] In this embodiment, a cutoff plane 10341 is provided in the near-beam collimator 1034. This allows the LED emitted light to reach the surface below the near-beam collimator 1034, where it is reflected and strikes other surfaces inside the second optical component. The light then undergoes further reflection and transmission until it reaches the exit surface of the second optical component 103. After passing through the first optical component 101, the light enters and exits. This controls and ensures that most of the light emitted from the first optical component 101 has a non-large angle, allowing it to approach the correct transmission direction and achieve optimal light efficiency and optical effects. The light reaching the surface below the near-beam collimator 1034 is reflected, ensuring that this portion of the light transmission remains within the second optical component 103 and does not escape, decrease, or become uncontrollable through the air. This ensures that as much light as possible and its transmission are contained within the second optical component 103.

[0092] Not every collimation section 1034 needs to have a cutoff plane 10341; it should be selected according to specific design requirements.

[0093] like Figure 9 As shown, the high beam unit 1031 can be horizontally positioned. Figure 9 The viewing angle is not horizontal (horizontal refers to the XY plane of the vehicle body coordinate system), but it can also be set at a downward tilt of 5.7 degrees. The outer curvature of the low beam 1032 is large, so in order to make the low beam unit closer together in the design, more LED curvature is set and the setting is more compact.

[0094] The low beam collimator 1034 is positioned relatively close to the right side of the diagram because the outer curvature of the entire lamp and module is relatively large. Figure 16The right side of the first optical component 101 shown has a larger curvature, and the lower side is closer to the right side structure of the second optical component 103. Therefore, in order to meet the design requirements that the second optical component 103 and the first optical component 101 are close together, the low beam section 1032 (including its low beam basic light pattern section) needs to be equipped with more LED light sources to ensure that the light pattern and light effect meet regulatory requirements. The low beam collimation section 1034 is set more compactly near the outer part.

[0095] like Figure 13 As shown, the first optical component 101 is shown in an EE cross-sectional view. The left side of the first optical component 101 is used for low beam function, and the right side of the first optical component 101 is used for high beam function.

[0096] Figure 15 This is the front view of the module. Figure 16 It is an FF sectional view. Figure 17 This is a cross-sectional view of the low beam principle. Figure 18 This is a cross-sectional view of the high beam principle. Figure 17 In addition to the aforementioned light path information for the cut-out surface 10341, it also includes the near-beam light path shown in black in the diagram. The light emitted from the LED hits the collimating structure. A portion of the light from the collimating structure hits the lower side (between the near-beam collimating part 1034 and the end face 1035) and is reflected to the light-emitting surface of the second optical component 103. The light then exits to the first optical component 101 and outputs a light pattern. Another portion of the light from the collimating structure directly hits the light-emitting surface of the second optical component 103, and then hits the first optical component 101 for incident and outgoing light patterns.

[0097] Figure 18 The light emitted from the LED hits the collimation structure, then hits the light-emitting surface of the second optical component 103, and is emitted to the first optical component 101 for further incident and emission, outputting a high-beam light pattern.

[0098] The low beam module is shown in cross-section. Figure 17 As shown, the light source component preferably consists of several LED light-emitting diodes, which are packaged on a PCB printed circuit board with control functions.

[0099] Furthermore, since the heat generated during the operation of the light source has a significant impact on the luminous efficiency of the LED, a large-area heat dissipation component 106 is required to dissipate the excess heat generated. This component contains multiple clusters of heat dissipation fins, which can better exchange the heat inside the module with the external space.

[0100] The light emitted from the PCB board and the light source is integrated at the rear end of the second optical component 103. The light source light with a wide diffusion angle is integrated into a low-diffusion light with a narrow diffusion angle. This light is then further integrated at the front end of the second optical component 103, allowing control of the light pattern diffusion angle. The vertical structure of the second optical component 103 can form a cutoff line structure in the near-beam pattern. This cutoff line is located at the upper boundary of the illumination pattern. The cutoff line structure can be a broken line or a curve with an inflection point, used to form a near-beam cutoff line with an inflection point. Its illumination pattern can be a complete near-beam pattern or a main near-beam pattern projected onto the central area of ​​the near-beam; it can also be a straight line or an arc, used to form a horizontal near-beam cutoff line, whose illumination pattern can be an auxiliary near-beam pattern projected onto the near-beam broadening area. The cutoff line pattern with an inflection point and the horizontal cutoff line pattern can then be combined to form a complete near-beam pattern.

[0101] The first optical component 101 projects the integrated light onto the road surface. The first optical component 101 has a variety of shapes, and its outer surface can be adapted to meet customer design requirements. The inner surface can be modified based on the determined outer surface, projecting the near-beam pattern image of the cross-section of the second optical component 103 onto the road surface in front of the vehicle. The clamping component 102 serves as a support for the first optical component 101 and can fix the first optical component 101 to the entire module using connection methods such as snap-fit ​​screws and laser welding. Furthermore, the clamping component 102 can conceal internal optical components and protect the core internal optical components.

[0102] Cross-section of the high beam module Figure 18 As shown, its principle is roughly the same as that of the low beam. The difference is that since the high beam has no cutoff line, there is no vertical structure forming a cutoff line in the second optical component 103.

[0103] This invention employs a second optical component to integrate high and low beam functions into the same module, achieving an ultra-narrow aperture module.
