Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and in particular to an integrated LED vehicle light with high beam supplementation function. Background Technology

[0002] In recent years, LED technology has gradually become the mainstream light source for automotive headlights due to its advantages such as high brightness, low energy consumption, and long lifespan. Based on this, integrated LED headlight technology for both high and low beams has developed rapidly.

[0003] Related technologies can be found in Chinese Utility Model Patent No. CN216693409U. This utility model discloses an LED high and low beam headlight module, including a connecting housing, a heat dissipation device installed on the right side of the outer surface of the connecting housing, a heat extraction device installed on the rear side of the outer surface of the connecting housing, and a lamp device installed on the front side of the outer surface of the connecting housing. An adjustment data plate is provided on the upper side of the outer surface of the main housing of the high and low beam lamp device, and a power-on contact plate is provided on the left side of the outer surface of the main housing of the high and low beam lamp device. The lamp device includes an LED lamp housing, which is installed on the right side of the heat dissipation graphite frame. A convex mirror plate is provided on the surface of the LED lamp housing. The LED high and low beam headlight module provided by this utility model has the advantages of front and rear spaced installation and fixation, reasonable structure, lightweight materials, low overall load-bearing capacity, and a rear heat extraction fan that can dissipate heat in a timely manner, preventing the internal ambient temperature from continuously rising, thus ensuring the stability of the internal working environment and improving the overall service life.

[0004] However, the existing high and low beam headlights still have the following shortcomings: the light-blocking adjustment flap can only adjust the high beam and low beam modes of the headlights. In high beam mode, the low beam headlights provide limited supplementary light to the high beam headlights, resulting in insufficient improvement in the illumination range and center brightness, which affects driving safety in complex road conditions. Utility Model Content

[0005] This application provides an integrated LED vehicle headlight with high beam supplementation function, which solves the problem that the light-shielding adjustment plate can only adjust the high beam and low beam modes of the headlight. In the high beam mode, the low beam has limited supplementation to the high beam, resulting in insufficient improvement in the illumination range and center brightness, which affects driving safety in complex road conditions.

[0006] The technical solution adopted in the embodiments of this application is as follows: In a first aspect, embodiments of this application provide an integrated high and low beam LED vehicle headlight with high beam supplementation function, comprising a lens, a lens bracket detachably connected to the lens, a light-blocking component located inside the lens bracket, and a cooling fan detachably connected to the end of the lens bracket away from the lens. A high beam lamp plate is detachably connected to the inner surface of the lens bracket, a high beam lamp source is fixedly connected to one side of the high beam lamp plate near the lens, and an auxiliary heat sink is detachably connected to the other side. A support is detachably connected to the inner surface of the lens bracket, the support is located above the auxiliary heat sink and snaps into the auxiliary heat sink, a low beam lamp plate is detachably connected to the upper surface of the support, and a control board is detachably connected to the lower surface of the support. A low beam lamp source is fixedly connected to the upper surface of the low beam lamp plate, and a main heat sink is detachably connected to both sides of the support. The light-blocking component includes a flip-shaped light-blocking plate, a base rotatably connected to the flip-shaped light-blocking plate, and an electromagnet fixed to one side of the base. The flip-shaped light-blocking plate can flip under the attraction of the electromagnet, allowing more low beam light to pass through.

[0007] By adopting the above technical solution, the high beam and low beam modules are independently set up and integrated into the lens bracket and support, constructing physically isolated and functionally independent light source modules. The low beam source works in conjunction with the high beam source in high beam mode, rather than solely relying on the entire light output of the high beam source. When the electromagnet engages, causing the flip-type light-blocking plate to move, it partially removes the obstruction of the low beam source, allowing the low beam source to effectively supplement the high beam source, thus expanding the effective illumination range and depth of vision, and improving driving safety.

[0008] In one optional implementation, both the low beam light source and the high beam light source are provided as two.

[0009] By adopting the above technical solution, both the low beam and high beam sources are configured as two. In low beam mode, the two low beam sources can provide uniform and wide basic lighting. When switching to high beam mode, the two high beam sources and the two unshielded low beam sources together form a lighting array consisting of four light sources, achieving a wider, more uniform, and high-quality high beam lighting effect without significant dark areas.

[0010] In one optional implementation, a low beam reflector is fixedly connected to the upper surface of the support. The low beam reflector has a double-chamber cover structure, with the two chambers covering two low beam light sources respectively. The two chambers of the low beam reflector are not interconnected.

[0011] By adopting the above technical solution, a low beam reflector with an independent dual-chamber structure is installed. Each chamber can independently guide light in a preset direction and shape it into the desired light pattern. The structure in which the two chambers are not interconnected fundamentally reduces the cross-interference and scattering of light from different low beam sources in the initial stage of reflection, thereby improving the standardization and anti-glare effect of low beam lighting and ensuring safety when meeting oncoming traffic at night.

[0012] In one alternative implementation, the light-blocking assembly further includes a right-angle light-blocking plate fixed to the middle of the base near the lens side, the right-angle light-blocking plate being located at the connection of the two chambers of the near-light reflector.

[0013] By adopting the above technical solution, a right-angle light-blocking plate is added to the light-blocking assembly. This light-blocking plate is precisely positioned at the physical connection point of the two independent chambers of the low beam reflector. In low beam mode, when the flip-type light-blocking plate is in its original position, this right-angle light-blocking plate can effectively block the small amount of stray light that may leak from the connection gap between the two low beam reflector chambers, thereby improving the quality of low beam illumination.

[0014] In one alternative implementation, two cooling fans are provided, which are detachably connected to the support via fan grilles.

[0015] By adopting the above technical solution and using a dual cooling fan configuration, the two fans can form a stronger and wider directional airflow, which can directly and efficiently blow air onto the main heat sink and the area where the secondary heat sink connected to the lens bracket is located, thereby enhancing the heat dissipation efficiency.

[0016] In one alternative implementation, the lens bracket has a plurality of recesses at one end near the lens that match the geometry of the lens side, and is equipped with a fixing member of the same shape, the fixing member being detachably connected to the lens bracket.

[0017] By adopting the above technical solution, the concave contour fits tightly with the side of the lens, ensuring that the lens can be accurately positioned on the preset optical central axis during installation, reducing the decline in optical performance caused by installation deviation. The matching fastener provides uniform locking force, firmly constraining the lens in the concave, thus achieving the effect of fast, accurate and reliable lens installation.

[0018] In one alternative implementation, the main heat sink and the secondary heat sink are thermally connected via a lens bracket.

[0019] By employing the above technical solution, the lens bracket acts as a bridge for heat conduction, physically isolating but thermally connecting the main radiator serving the low beam source and the auxiliary radiator serving the high beam source. The highly thermally conductive lens bracket combines and distributes the heat generated by the auxiliary radiator and the high beam panel with the heat carried by the main radiator. This thermal connection design reduces the problem of independent operation and isolated thermal fields of each radiator in traditional designs, which leads to excessively high temperatures in local hot spots, thereby improving the heat dissipation limit and thermal stability of the entire vehicle lighting system.

[0020] In one alternative implementation, the main heat sink, the secondary heat sink, and the lens bracket are all made of materials with high thermal conductivity.

[0021] By adopting the above technical solution, the main heat sink, the secondary heat sink, and the lens bracket are all made of materials with high thermal conductivity, which further improves the heat conduction efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This headlight utilizes independently designed dual-light source modules for high and low beams, which work together in high beam mode. Combined with a rotating light-blocking plate, this effectively supplements the high beam with low beam illumination, significantly expanding the lighting range and depth of vision. The dual reflector structure and right-angle light-blocking plate design effectively control light distribution, improving the low beam's anti-glare effect and beam pattern consistency, thus ensuring driving safety. 2. This headlight employs a thermally connected structure between the main and auxiliary heat sinks and the lens bracket, combined with a dual-fan system, to create a highly efficient and collaborative heat dissipation system. The use of high thermal conductivity materials further optimizes thermal management efficiency, ensuring that the LED light source operates at a stable temperature, significantly improving overall heat dissipation performance and system reliability.

[0028] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. It should be understood that when component A is fixedly connected to component C via component B, changes in the relative positional relationship due to deformation of components A, B, and C are permissible. The integrated structure obtained by the two components through a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components.

[0029] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "side", etc., are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0030] The term "multiple" refers to at least two. The term "more than" includes the stated number. The term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] This application discloses an integrated LED vehicle headlight with high beam and low beam supplementary lighting function.

[0032] Reference Figure 1 A high-beam and low-beam integrated LED vehicle headlight with high beam supplement function includes a lens 1, which is injection molded from optical-grade polycarbonate material. The front surface of the lens 1 is a smooth convex surface, and the rear surface is designed with optical textures.

[0033] It also includes a lens holder 3, which is made of aluminum alloy with high thermal conductivity and has a cylindrical structure. One pair of opposing surfaces are flat horizontal surfaces, while the other pair of opposing surfaces are curved surfaces, and there is an internal cavity. At the light-emitting end of the lens holder 3, there are three recesses, the shape of which matches the geometry of the edge of the lens 1.

[0034] Lens 1 and lens bracket 3 are connected by bolts through fastener 2. There are three fasteners 2, which correspond to three recesses on lens bracket 3. The contours of these recesses are machined to ensure a tight fit with the edge of lens 1.

[0035] Reference Figure 1 and Figure 2 On the lower inner surface of the lens bracket 3, a high beam light panel 8 is detachably connected by bolts. This light panel is a rectangular aluminum-based circuit board. On the side of the high beam light panel 8 near the lens 1, two high-power LED chips are fixedly connected as high beam light sources 9.

[0036] Reference Figure 2 On the side of the high beam panel 8 away from the lens 1, a secondary heat sink 10 is detachably connected by thermally conductive adhesive. The secondary heat sink 10 is composed of multiple aluminum heat dissipation fins.

[0037] Reference Figure 1 and Figure 2 Above the inner surface of the lens bracket 3, a support 12 is detachably connected by bolts. This support 12 is a U-shaped aluminum alloy component, located above the auxiliary heat sink 10, and is snapped into the auxiliary heat sink 10 via a snap-fit ​​structure. On the upper surface of the support 12, a low beam lamp plate 14 is detachably connected by screws. This lamp plate is also an aluminum-based circuit board. On the upper surface of the low beam lamp plate 14, two LED chips are fixedly connected as low beam light sources 11, arranged symmetrically with the high beam light source 9.

[0038] On the lower surface of the support 12, a control board 13 is bolted on, which integrates drive circuitry and protection components. On both sides of the support 12, a main heat sink 4 is detachably connected by bolts. Each main heat sink 4 consists of a copper substrate and extended aluminum heat dissipation fins.

[0039] A low-beam reflector 5 is fixedly connected to the upper surface of the support 12. This reflector is a double-chamber cover structure, injection molded from PET. The two chambers precisely cover the two low-beam lamp sources 11, and the chambers are physically isolated from each other by a partition, and are not interconnected. The inner surface of each chamber is an optically optimized reflective surface, which can independently guide light to form the desired light pattern.

[0040] Inside the internal cavity of the lens holder 3, a light-blocking assembly is located behind the lens 1. This assembly includes a flip-type light-blocking plate 17, a base, and an electromagnet 7. The base is fixed to the inner wall of the lens holder 3 by a snap-fit ​​mechanism. The flip-type light-blocking plate 17 is rotatably connected to the base via a pivot. The electromagnet 7 is fixed to one side of the base and drives the light-blocking plate to flip by the magnetic force generated when energized. A right-angle light-blocking plate 6 is also fixedly connected to the center of the base of the light-blocking assembly, near the lens 1. This light-blocking plate is located at the connection point between the two chambers of the near-light reflector 5.

[0041] Reference Figure 1 and Figure 3 At the end of the lens bracket 3 furthest from the lens 1, two cooling fans 15 are bolted together. Two fan grilles 16 are fixed to the non-exhaust ends of the two cooling fans 15. The fan grilles 16 have a metal mesh structure, as shown in the reference diagram. Figure 2 The airflow generated by the fan blows directly onto the main heatsink 4 and the secondary heatsink 10 area.

[0042] Reference Figure 1 and Figure 2 The main heat sink 4, the secondary heat sink 10 and the lens bracket 3 are all made of materials with high thermal conductivity, and are thermally connected through the lens bracket 3 to form a unified thermal management system.

[0043] The implementation principle of an integrated high / low beam LED vehicle light with high beam supplementary lighting function in this application embodiment is as follows: Independently configured high beam and low beam dual-light source modules work collaboratively with the assistance of a light-blocking component. When the electromagnet 7 is attracted, causing the flip-shaped light-blocking plate 17 to move, it releases part of the obstruction of the low beam light source 11, allowing the low beam light source 11 to effectively supplement the high beam light source 9. Simultaneously, the combined design of the dual-chamber low beam reflector 5 and the right-angle light-blocking plate 6 effectively controls the light distribution, improving the standardization and anti-glare effect of low beam illumination. The heat dissipation system, through the thermal connection structure between the main and auxiliary heat sinks 10 and the lens bracket 3, combined with a dual-fan configuration, constructs a highly efficient and collaborative heat dissipation system, ensuring that the LED light source operates at a stable temperature and significantly improving the overall system reliability.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.
