[0002] With the development of vehicle lighting technology, more and more OEMs and users need more intelligent vehicle lighting systems, and the requirements for safety are getting higher and higher. In addition to the traditional adaptive low beam AFS system (Adaptive Front-Lighting System), there is also ADB (Advanced Driving Beam) technology that can prevent dazzling other vehicle drivers and improve safety.

[0003] The technology currently available on the market to achieve adaptive high and low beams is pixelated ADB headlights. Generally, each LED is controlled individually through the number of pixelated LEDs, or through pixelated optical components, such as a concentrator plus an LED optical system, so as to control the pixels in a specified area to turn off, thereby preventing glare for drivers of oncoming or same-direction vehicles and improving safety. Figure 1 However, pixelated ADB headlights require an increase in the number of LED control chips, which is very costly, has a large number of parts, and is complex to install and assemble.

[0012] When the lower pixel region and / or the upper pixel region of the pixel region needs to be turned off: the lower shielding structure is located in the lower pixel region and / or the upper shielding structure is located in the upper pixel region.

[0013] Preferably, the automobile lamp module further comprises: a plurality of driving components;

[0014] The shielding structure and the driving component are connected in a one-to-one driving manner, and the driving component can drive the shielding structure to move into the pixel area and / or out of the pixel area.

[0015] Preferably, the single driving assembly comprises: a lower driving assembly and an upper driving assembly;

[0016] The lower driving component is drivingly connected to the lower shielding structure, and the lower driving component can drive the lower shielding structure to move into the lower pixel area and / or move out of the lower pixel area;

[0017] The upper driving component is drivingly connected to the upper shielding structure, and the upper driving component can drive the upper shielding structure to move into the upper pixel area and / or move out of the upper pixel area.

[0018] Preferably, the driving component is an electromagnetic coil component;

[0019] When the current flowing in the electromagnetic coil component is in a first current direction, the electromagnetic coil component generates a suction force on the shielding structure, driving the shielding structure to move out of the pixel area so that the shielding structure is located outside the pixel area;

[0020] When the current flowing in the electromagnetic coil component is in a second current direction opposite to the first current direction, the electromagnetic coil component generates a repulsive force on the shielding structure, driving the shielding structure to move into the pixel area so that the shielding structure is located in the pixel area.

[0021] Preferably, the automobile lamp module further comprises: a limiting bracket structure;

[0022] When the shielding structure moves out of the pixel area and / or moves into the pixel area, the shielding structure is limited by the limiting bracket structure.

[0023] Preferably, a plurality of the shielding structures are arranged in a horizontal direction;

[0027] Preferably, the optical structure is a reflective bowl; the light source is placed horizontally, and the light emitting direction of the light source is vertical;

[0028] Alternatively, the optical structure is a lens structure; the light source is placed vertically, and the light emitting direction of the light source is horizontal.

[0029] The present invention also provides a car, comprising the above-mentioned car light module capable of turning pixels on and off.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention sets a plurality of shielding structures for a light source, and the plurality of shielding structures are respectively used to shield different areas of the light emitting area of ​​the light source in the horizontal direction, so as to achieve the effect of pixelating the light emitting area of ​​a single light source. When N shielding structures are set along the horizontal direction, it is equivalent to dividing the light emitting area into N pixels. Without setting so many LEDs, a good pixelation effect can still be achieved, thereby reducing the number of LEDs set and reducing the cost.

[0032] 2. The present invention further arranges an upper shielding structure and a lower shielding structure in the same area, which can realize shielding of different areas in the vertical direction while realizing shielding of different areas in the horizontal direction, further increasing the pixelation effect, which is equivalent to further dividing a single pixel into two sub-pixels up and down, and the entire light-emitting area is equivalent to being divided into 2N sub-pixels, thereby improving the pixel effect.

[0033] 3. The present invention solves the problem of realizing pixelated high beam and low beam by adopting an adjustable energized coil plus a shielding structure modular structure, thereby achieving the effect of ADB or pixelated low beam at a relatively low cost.

[0034] 4. The present invention solves the problem of high cost of ADB in the prior art by increasing the number of LEDs and controlling each LED individually by adopting an adjustable shielding structure. The present invention reduces the number of assembly parts and electronic components by using fewer LEDs and controlling the shielding structure, thereby reducing the difficulty of assembly and greatly reducing costs.

[0035] 5. The present invention reduces the power consumption of the entire system. If the pixelated high and low beams are realized by conventionally controlling the on and off of LEDs, the electronic components are always in working state and the number of LEDs is large. However, the present system makes the shielding structure work only when there is an oncoming vehicle or a forward vehicle, and the working time is limited and only applies to the oncoming vehicle state. This not only reduces the system cost but also reduces the energy consumption of the entire system.

[0036] 6. The shielding structure and electromagnetic components of the present invention are made into standard modules, which are more flexible in design. If a failure occurs later, the cost of replacing the standard module is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0056] Embodiment 1:

[0057] like Figure 2 and Figure 3 As shown, this embodiment provides an automobile lamp module capable of realizing pixel on and off, including: a light source 1 and a plurality of shielding structures 6; the plurality of shielding structures 6 are arranged corresponding to the light emitting area of ​​the light source 1, and the plurality of shielding structures 6 correspond to different areas of the light emitting area respectively, and the area corresponding to a single shielding structure 6 is a pixel area of ​​the light emitting area; when the light emitting area is normally lit: the plurality of shielding structures 6 are all located outside the pixel area, and the light emitted by the light source 1 is emitted through the light emitting area; when one or more pixel areas of the light emitting area need to be extinguished: the shielding structures 6 corresponding to the pixel areas to be extinguished are located in the pixel area to shield the light. The automobile lamp module also includes: a plurality of driving components 8; the shielding structures 6 and the driving components 8 are connected in a one-to-one driving manner, and the driving components 8 can drive the shielding structures 6 to move into the pixel area and / or out of the pixel area. The plurality of shielding structures 6 are arranged in a horizontal direction; when the plurality of shielding structures 6 are all located in the pixel area, the plurality of shielding structures 6 can completely cover the entire light emitting area.

[0058] Take 12 pixel areas as an example. Figure 7 As shown in the figure, it is a schematic diagram of the effect that all pixel areas are not blocked, and the white block area is the pixel area. Figure 8 As shown, it is a schematic diagram of the effect when two pixel areas are blocked, and the black block area is the area where the blocking structure is located.

[0059] The driving component 8 is an electromagnetic coil component; when the current flowing in the electromagnetic coil component is in a first current direction, the electromagnetic coil component generates an attractive force on the shielding structure 6, driving the shielding structure 6 to move out of the pixel area so that it is located outside the pixel area; when the current flowing in the electromagnetic coil component is in a second current direction opposite to the first current direction, the electromagnetic coil component generates a repulsive force on the shielding structure 6, driving the shielding structure 6 to move into the pixel area so that it is located inside the pixel area. The automobile lamp module also includes: a limiting bracket structure 7; when the shielding structure 6 moves out of the pixel area and / or moves into the pixel area, the limiting bracket structure 7 limits the shielding structure 6. The limiting bracket structure 7 can be a baffle plate set on a fixed frame. When the shielding structure 6 moves to the baffle plate position, the baffle plate blocks the movement of the shielding structure 6 to achieve limiting, thereby making the shielding structure 6 in a preset position.

[0060] Driven by suction and repulsion, the stability of the shielding structure can be better guaranteed. If no force acts on the shielding structure, the slight vibration of the car during driving will cause the shielding structure to shake, which will affect the light output.

[0061] The automobile lamp module also includes: an optical structure 4 and an outer lens 5; when the light emitting area is normally lit: the light emitted by the light source 1 is adjusted by the optical structure 4, passes through the light emitting area to the outer lens 5, and then exits through the outer lens 5. In this embodiment, the optical structure 4 is a lens structure 402; the light source 1 is placed vertically, and the light emitting direction of the light source 1 is horizontal. The light source 1 is integrated on the PCBA board 2, and the PCBA board 2 is integrated on the heat sink 3.

A single driving component 8 includes: a lower driving component 801 and an upper driving component 802; the lower driving component 801 is drivingly connected to the lower shielding structure 601, and the lower driving component 801 can drive the lower shielding structure 601 to move into the lower pixel area and / or move out of the lower pixel area; the upper driving component 802 is drivingly connected to the upper shielding structure 602, and the upper driving component 802 can drive the upper shielding structure 602 to move into the upper pixel area and / or move out of the upper pixel area.

[0069] The structure of the lower driving component 801 and the structure of the upper driving component 802 are the same as the driving component 8 in Example 1. The driving method of the lower driving component 801 on the lower shielding structure 601 and the driving method of the upper driving component 802 on the upper shielding structure 602 are the same as the driving method of the driving component 8 in Example 1.

[0070] Embodiment 4:

[0071] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the single shielding structure 6 includes: a lower shielding structure 601 and an upper shielding structure 602; the lower shielding structure 601 and the upper shielding structure 602 are respectively arranged corresponding to the upper pixel area and the lower pixel area of ​​a single pixel area; when the pixel area is normally lit: the lower shielding structure 601 is located outside the lower pixel area, and the upper shielding structure 602 is located outside the upper pixel area; when the lower pixel area and / or the upper pixel area of ​​the pixel area needs to be turned off: the lower shielding structure 601 is located in the lower pixel area and / or the upper shielding structure 602 is located in the upper pixel area.

[0073] like Fig. 9 As shown, there are two pixel areas on the left and right that are completely blocked, and there are two pixel areas in the middle that only have the upper pixel areas blocked.

[0074] Embodiment 5:

[0075] Those skilled in the art may understand this embodiment as a more specific description of Embodiments 1-4.

[0076] This embodiment provides an adaptive smart headlight that uses fewer LEDs, is low-cost, and saves space.

[0077] The difficulty of implementing ADB with electromagnet: ordinary high and low beam switching only requires one light shielding piece, while ADB has multiple pieces. When implementing adaptive high beam, the shielding structure must work continuously, which makes it more difficult to implement. In the patent literature of background technology, it is not necessary to work when implementing the high beam function, and in this embodiment, the shielding structure 6 and the electromagnetic component 8 are made into standard modules, which are more flexible in setting. If a failure occurs later, the cost of replacing the standard module is lower.

[0078] Compared with the function switching between ordinary high and low beams through electromagnetic drive, the present embodiment realizes adaptive high beam through electromagnetic drive. In terms of function realization, the former is function switching, and the latter is an upgrade within a single function, and the purposes of realization are different. In terms of technical difficulty, the former is a choice between two, either low beam or high beam, the choice between 0 and 1, and both the size of functional components and the functions realized are relatively simple. The present embodiment realizes adaptive high beam through electromagnetic drive, which is an upgrade within a single function, i.e., an advanced version of high beam. The number and size of the drives and the complexity of the system are not linearly accumulated.

[0079] like Figure 7 and Figure 8 As shown, this embodiment takes dividing the light emitting area into 12 pixels as an example.

[0080] The adaptive intelligent headlight of this embodiment includes: a light source 1, a PCBA board 2, an outer lens 5, an optical structure 4, a shielding structure 6 and an electromagnetic component 8.

[0081] The adjustable shielding structure can be composed of many pieces according to the optical design requirements. The shielding structure 6 and the electromagnetic component 8 are made into standard modules, and different numbers of standard modules can be freely matched according to different pixel number requirements. For example, for 12 pixels, 12 standard modules can be selected accordingly.

[0082] The shielding structure can be moved and controlled by the energized coil. When the energization direction is the first current direction, the energized coil generates suction on the shielding structure, driving the shielding structure to move downward. The shielding structure is located below the light emitting area, and the light emitted from the LED on the PCB enters the optical structure (it can be penetrated into the lens or reflected by the reflective bowl), forming a cutoff line in the shielding structure. At this time, the optical system produces a complete high beam or low beam light type. When it is necessary to deal with vehicles coming in the same or opposite directions, the energization direction of the energized coil of the shielding structure in the corresponding area can be adjusted to a second current direction opposite to the first current direction, thereby generating a repulsive force to lift up several shielding structures in the corresponding area. At this time, the light shielding sheet is in a vertical position, so the light cannot pass through, and the light is blocked, so that the corresponding light type area produces a dark area, thereby realizing the ADB function and achieving an anti-glare effect.

[0083] like Figure 7 As shown, there can be 12 shielding plates. When all shielding plates are in a horizontal position, all high beams are normally lit. When there are vehicles coming from the opposite or same direction, the effect is as follows Figure 8 As shown, when the shielding piece in the corresponding area is in the vertical position, part of the high beam area will be turned off, thereby realizing the ADB function and achieving an anti-glare effect.

[0084] Figure 3 It is a projection system. Figure 4 For a reflective system, Figure 5 It is a two-layer reflective system. Figure 6 It is a two-layer projection system.

[0085] Furthermore, according to the different numbers of adjustable shielding structures, different numbers of pixels of the system can be realized, and the design is more flexible.

[0086] Furthermore, according to the requirements of optical design, the shielding structure can be made into two layers, and the light-extinguishing area can be further refined. Fig. 9 Through the standard modular structure, the required extinguishing areas can be freely combined to achieve a variety of anti-glare effects and improve efficiency.

[0087] Furthermore, this embodiment is applicable to ordinary high beam, low beam, high and low beam integrated, ADB, left and right steering, etc.

[0088] Furthermore, the light source can be a SMD LED integrated on a PCBA or integrated on a heat sink, connected to a PCB board via a metal wire, a laser light source, or other light source types can be selected according to actual needs.

[0089] Furthermore, the placement of the light source assembly in the entire vehicle lamp module space depends on the specific optical system used, and can be placed horizontally or vertically, such as Figure 3 and Figure 4 As shown, there are two different optical systems with different light sources placed in different positions.

[0090] Furthermore, the shielding structure itself can be made of iron or other materials. When the power coil is energized, it generates magnetic force, which lifts up a piece of the shielding structure. Alternatively, the shielding structure is not made of iron, and the structural parts are used to limit and adjust. The power coil generates magnetic force to push the mechanical arm, and the mechanical arm pushes the shielding structure. The specific implementation method is determined according to the actual space and situation.

[0091] Furthermore, the shielding structure may also be a plastic part, in which a magnet is injection-molded.

[0092] Furthermore, the electromagnetic generated by the coil can be shielded by adding a shielding cover structure.

[0093] Embodiment 6:

[0094] Those skilled in the art may understand this embodiment as a more specific description of Embodiments 1-4.

[0095] The headlight module of the present embodiment includes: a light source assembly, an outer lens for realizing optical performance and an optical structure for realizing high and low beams in cooperation with the outer lens, an adjustable shielding structure, and a bracket and a lining frame for fixing the above components. The light source assembly of the module is located at the innermost end of the entire structure, and from the inside to the outside are the light source assemblies of the module. Its light is matched with the outer lens to realize the optical structure of high and low beams, and it needs to cooperate with the outer lens to form a complete optical system. The adjustable shielding structure is located in the middle of the entire system, and by controlling the operation of different shielding structures, it can block the area that needs to be extinguished. The bracket and the lining frame are used to fix the various components of the entire module to make it a whole, and to cooperate with the shielding structure.

[0096] The entire automobile light module is realized through inner and outer lenses, light source components, outer lenses that realize optical performance, and optical structures that cooperate with outer lenses to realize high and low beams, to realize a basic high beam or low beam light type, or a module that integrates high and low beams. Through the adjustable shielding structure, which is composed of several pieces, it generates magnetic force to control its movement after the coil is energized. When the ADB function such as high beam is to be realized, when a car is driving in the opposite or same direction, a signal is given through the vehicle end, and the corresponding coil is energized to generate magnetic force to push the shielding structure at the corresponding position to work, which plays the role of extinguishing the light in the area.

[0097] Furthermore, the number of pixels of different high and low beams can be adjusted by changing the number of adjustable shielding structures according to the light type design requirements, for example, 12, 24, etc.

[0098] Furthermore, the cut-off line light type of the low beam can also be realized by working with different shielding sheets.

[0099] Furthermore, the light source assembly includes a light source, such as an LED light source or a laser light source, which is fixed on a PCB together with several electronic components, and a heat dissipation structure component behind the PCB board. It is also possible to directly integrate it on the heat dissipation structure component. The placement of the light source assembly in the entire vehicle lamp module space depends on the specific optical system used, and can be placed horizontally or vertically, such as Figure 3 and Figure 4 , are two different optical systems with different light sources.

[0100] Furthermore, the outer lens that realizes the optical performance and the optical structure that cooperates with the outer lens to realize the high and low beams are optical components that realize the high and low beams. The outer lens of the module is the outer lens of the module, and the inner implementation method can be selected according to the actual situation, such as a reflective bowl or a lens. Adjust the optical system according to the actual situation, such as Figure 3 and Figure 4 Two different optical systems are shown.

[0101] Further, the adjustable shielding structure, this part includes a shielding structure, which includes a shielding structure, the shielding structure is composed of many pieces, the shielding structure can be moved, when the shielding structure is located at the bottom, the bottom is controlled by the suction generated by the energized coil, the shielding structure itself can be made of iron, the energized coil contains an iron core, when the energization direction is the first current direction, the shielding structure is attracted by the iron core, at this time the shielding structure is located below the module, at this time the optical system produces a complete high beam or low beam. When the energization direction of the energized coil corresponding to a certain shielding structure is adjusted to the second current direction opposite to the first current direction, a repulsive force is generated, which lifts up a certain shielding structure, so that the corresponding light type area produces a dark area. The above is a design scheme for an adjustable shielding structure. It can also be that the shielding structure is not made of iron, and is limited and adjusted by certain structural parts. The energized coil generates magnetic force to push a certain mechanical arm, and the mechanical arm pushes a certain shielding structure. It can also be that a magnet is inserted into a plastic part and injected as a shielding structure. The specific implementation method is determined according to the actual space and situation. Depending on the number of adjustable shielding structures, different numbers of pixels in the system can be achieved. It can also be designed into an upper and lower shielding structure according to actual needs, as shown in the figure. The electromagnetic generated by the coil can be further optimized by adding a shielding cover structure.

[0102] Furthermore, the adjustable shielding structure needs to reach the target position after being lifted up by the electromagnetic force, so through the bracket and the lining frame structure, some limiting structures are made on it, so that the shielding structure is fixed by the limiting structure after reaching the target designated position, that is, the shielding structure blocks the light emitted by the optical system, and the limiting structure on the bracket is a limiting shielding structure to ensure that it can reach the designated position during the movement. It also has the inner and outer lenses of the fixed module, the light source assembly, the outer lens to achieve optical performance, and the optical structure that cooperates with the outer lens to achieve high and low beams, and the function of the adjustable shielding structure.

[0103] The structure of the present invention can be equipped with a high-definition camera to capture the road conditions ahead and the surrounding environment in real time. The image information obtained by the camera is processed by the vehicle's computing unit to identify information such as roads, pedestrians, and vehicles. Based on the processed data, the system sends a control signal to the drive component to drive the shielding structure in the corresponding area to achieve pixel-level shielding of light, so as to adjust the illumination range and brightness of the headlights, activate the shadow light type in the ADB headlights, and ensure the best lighting effect under different road conditions. It can also be equipped with sensors, control units, actuators, etc., and can automatically adjust the illumination range and brightness of the lights according to factors such as the vehicle's driving status, road conditions, and weather conditions.

[0104] The present invention drives the movement of the shielding structure through a driving component, thereby realizing the switching between non-shielding and blocking of light, and can realize the lighting and extinguishing of the light source pixel module in the corresponding area, thereby realizing the ADB function well, avoiding the problem of dazzling other vehicle drivers, and improving the safety factor.
