As a result, although the left and right headlamps of the vehicle have many display effects, the partition display cannot be achieved, that is, the lighting areas corresponding to different lighting functions may completely overlap, resulting in poor display effects corresponding to different display effects and low road lighting performance.

[0036] Next, the technical solutions in the present application will be clearly and exhaustively described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B. The "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality of" means two or more than two.
[0037] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0038] With the rapid development of intelligent vehicles, there are more and more display lamps on the vehicle. For example, currently, the vehicle is generally equipped with a front projection display screen, a rear projection display screen, interior projection lamps, and various display lighting lamps, etc. Among them, in order to enable the vehicle to display richer display effects based on the display lamps, the functions of the left and right headlamps of the vehicle are also increasing. For example, lighting, an Adaptive Driving Beam (ADB) intelligent high beam system, an Adaptive front-lighting system (AFS), a Dynamic Bending Light (DBL), an Automatic Headlamp Leveling System (ALS), etc.
[0039] However, in the related art, usually only the left and right headlamps of the vehicle can achieve the basic lighting display partition of high beam and low beam, and cannot achieve partition display based on other displays (such as ADB, DBL, etc.). As a result, although the left and right headlamps of the vehicle have many display effects, they cannot achieve partition display, that is, the lighting areas corresponding to different lighting functions may completely overlap, resulting in poor display effects corresponding to different display effects and low road lighting performance.
[0040] Therefore, the embodiments of the present application provide a lighting display device, a lighting display system, and a vehicle. The lighting display device can achieve partition display of low beam, high beam, projection, ADB, DBL, etc., so as to improve the display effect and road lighting performance of the left and right headlamps of the vehicle, and ensure the lighting reliability of the left and right headlamps of the vehicle.
[0041] The following will give an exemplary description of the lighting display device, the lighting display system, and the vehicle provided by the embodiments of the present application in combination with the drawings.
[0042] The lighting display system provided by the embodiments of the present application is applied to a vehicle, such as Figure 1As shown, the lighting display system may include a vehicle body domain controller 1, a lighting controller 2, a cockpit domain controller 3, and a lighting display device 4. Among them, the vehicle body domain controller 1, the lighting controller 2, and the cockpit domain controller 3 are respectively connected to achieve data communication. Specifically, the first end of the vehicle body domain controller 1 is connected to the first end of the cockpit domain controller 3 through a controller area network bus to achieve data communication. The second end of the vehicle body domain controller 1 is connected to the first end of the lighting controller 2. The vehicle body domain controller 1 is used to send a first message to the lighting controller 2. The second end of the cockpit domain controller 3 is connected to the second end of the lighting controller 2 through Ethernet. The cockpit domain controller 3 is used to send a second message to the lighting controller. The second message includes image information and / or animation signals. The lighting controller 2 can generate a first control signal according to the first message and can also generate a second control signal according to the second message. The lighting controller 2 is also connected to the lighting display device 4 and is used to receive the first control signal and / or the second control signal to correspondingly drive the display lamps in the lighting display device to emit light, so as to achieve the lighting display of the corresponding lighting display area.
[0043] Among them, the first control signal is a signal for controlling the lighting display state of the lighting display device 4. For example, low beam lighting display, high beam lighting display, turning lighting display, daytime position lighting display, anti-glare lighting display, or lighting height adjustable lighting display, etc. The second control signal is a signal for controlling the projection display state of the lighting display device 4. For example, symbol projection display, animation projection display, vehicle logo projection display, etc. That is, although both the first control signal and the second control signal are used to adjust the display state of the lighting display device 4, the specific display states adjusted are different. In this way, a lighting controller 2 can be used to adjust the lighting display state and the projection display state without adding an additional lighting adjustment system, and the structure is simple. Here, it is worth noting that, in order to enrich the display effect, the lighting controller 2 in the embodiment of the present application can control multiple display lamps in the lighting display device 4 to perform turning display and projection animation display simultaneously. In order to ensure the display accuracy of a single display lamp in the lighting display device 4, the lighting controller 2 in the embodiment of the present application can also control multiple display lamps to perform turning display or projection animation display separately at different times. For example, assuming that the user wants to remind other vehicles that the vehicle needs to turn left, the body domain controller 1 sends a turning signal to the lighting controller 2. If the lighting controller 2 is controlling other display lamps for projection based on the projection signal at this time, the lighting controller 2 can output a first control signal corresponding to the left turn to the display lamps in the lighting display device 4, and at the same time, stop outputting the second control signal corresponding to the projection signal to the projection lamps in the lighting display device 4 to avoid the problem that the turning display effect is low due to being affected by the projection animation during turning, so as to ensure the display accuracy of the display lamps. Specifically, corresponding settings can be made based on actual needs, and the present application does not make specific limitations in this regard.
[0044] Since two symmetric display lamps are usually arranged at the front of the vehicle, the lighting display system provided by the embodiment of the present application includes two lighting display devices 4 as shown in Figure 1 The third end of the lighting controller 2 is connected to one of the lighting display devices 4, and the fourth end of the lighting controller 2 is connected to the other lighting display device 4. The two lighting display devices are used to receive the first control signal and / or the second control signal to correspondingly drive the lamps in the lighting display device 4 to emit the light rays, so as to realize the lighting display of the corresponding lighting display area.
[0045] Next, taking one of the lighting display devices 4 as the left front lighting display device 4 and the other as the right front lighting display device 4 as an example, an exemplary description of the lighting display system and the lighting display device 4 provided by the embodiment of the present application will be given. Here, it is worth noting that the two lighting display devices 4 provided by the present application can also be display lamps symmetrically arranged at other positions, and the present application does not make specific limitations in this regard.
[0046] Since the left front lighting display device 4 and the right front lighting display device 4 are usually configured with various lighting and projection display effects. For example, low beam lighting display, high beam lighting display, turning lighting display, daytime position lighting display, anti-glare lighting display, lighting height adjustable lighting display, symbol projection display, animation projection display, and vehicle logo projection display, etc. In order to avoid the mutual influence between each lighting and projection display due to the overlapping of the display areas, resulting in poor display effects and low road lighting performance for each display, the lighting display device 4 in the present application can achieve zoned display of low beam, high beam, projection, ADB, and DBL, etc., so as to improve the display effect and road lighting performance of the left front lighting display device 4 and the right front lighting display device 4, that is, to improve the lighting reliability of the left front lighting display device 4 and the right front lighting display device 4.
[0047] In one example, as Figure 2 shown, the lighting display device 4 provided by the embodiment of the present application includes a first lighting module 41, a second lighting module 42, a third lighting module 43, and a housing 44. The first lighting module 41, the second lighting module 42, and the third lighting module 43 are arranged side by side in the housing 44. That is, the housing 44 plays a role of receiving and protecting the three lighting modules. When the vehicle is provided with a left front lighting display device 4 and a right front lighting display device 4, that is, two housings are provided at this time, and the two housings are symmetrically arranged on the left and right of the front of the vehicle body.
[0048] Among them, in one example, as Figure 3 shown, the first lighting module 41 may include a first lamp 411 and a first lens 412. The first lens 412 covers the first lamp 411. The light of the first lamp 411 irradiates a preset distance after passing through the first lens 412 to form an illumination display area. The light of the first lamp 411 irradiates on the first preset distance A after passing through the first lens 412 to form a first illumination display area 41a with the first lamp as a unit. The light of the first lamp 411 irradiates on the second preset distance B after passing through the first lens 412 to form a second illumination display area 41b with the first lamp 411 as a unit. Assuming that the first lighting module 41 is a low beam and high beam dual-light module at this time, then as Figure 4 shown, the first illumination display area 41a corresponds to the low beam lighting display, and the second illumination display area 41b corresponds to the high beam lighting display. Therefore, the second preset distance B is greater than the first preset distance A. In this way, the first lighting module 41 can achieve zoned display of low beam lighting display and high beam lighting display, and a low beam cut-off display area 41c is provided between the zoned display of low beam lighting display and high beam lighting display to further distinguish the low beam lighting display and the high beam lighting display.
[0049] In this example, the low-beam cut-off display area 41c can be 320×8 pixels, and the first lighting display area 41a can be 320×12 pixels.
[0050] In order to prevent a large jump in the lighting area when switching from low-beam lighting display to high-beam lighting display, which may affect the experience, optionally, there is a partially overlapping area between the first lighting display area 41a and the second lighting display area 41b. This overlapping area is the first transition area 41d. When the first lighting module 41 switches from the first lighting display area 41a to the second lighting display area 41b, that is, from low-beam lighting display to high-beam lighting display, the first transition area 41d is always in the lighting display state. This avoids a large jump between the two areas during the low-high beam lighting display switch, which may pose a certain safety hazard, and improves the safety of switching low-high beam lighting during vehicle driving.
[0051] In one example, as Figure 5 shown, the second lighting module 42 includes a second lamp 421 and a second lens 422. The second lens 422 covers the second lamp 421. The light of the second lamp 421 passes through the second lens 422 and irradiates at a preset distance to form a lighting display area. The light of the second lamp 421 passes through the second lens 422 and irradiates at a third preset distance C to form a projection display area 42a with the second lamp 421 as a unit. The light of the second lamp 421 passes through the second lens 422 and irradiates at a fourth preset distance D to form a third lighting display area 42b with the second lamp 421 as a unit. Assuming that the second lighting module 42 is a Light Emitting Diode (LED) projection module at this time, then as Figure 6 shown, the projection display area 42a corresponds to approach projection display, and the third lighting display area 42b corresponds to high-precision ADB display or high-precision DBL display. At this time, in order to prevent the projection display from affecting the high-precision ADB display or high-precision DBL display, the distances of the third preset distance C and the fourth preset distance D are different, that is, the fourth preset distance D can be greater than the third preset distance C. In this way, the projection display area 42a will not affect the third lighting display area 42b that needs to achieve high-precision lighting display. The second lighting module 42 can achieve partitioned display of the projection display area 42a, high-precision ADB display or high-precision DBL display, improving the display effect and road lighting performance of the projection display area 42a, high-precision ADB display or high-precision DBL display, and enhancing the reliability of projection display and lighting of the projection display area 42a, high-precision ADB display or high-precision DBL display.
[0052] In this example, the projection display area 42a can be 320×47 pixels, and the third illumination display area 42b can be 320×33 pixels. Here, it is worth noting that the second lighting module 42 can have multiple usage scenarios, such as lighting safety scenarios, driving etiquette scenarios, intelligent interaction scenarios, auxiliary support scenarios, and entertainment life scenarios, etc. Its multiple usage scenarios can specifically include external atmosphere, etc., night driving lights, driver assistance projection, pedestrian reminder, road surface markings, obstacle markings, welcome light carpet, vehicle condition information reminder, fixed-value animation, guiding signs, light shows, game voting, and concerts, etc., for various lighting displays or partition displays of projections. For this, it can be set based on actual needs, and this application does not make specific restrictions on this.
[0053] Since the second lighting module 42 needs to perform projection display, in order to ensure the picture quality such as the clarity, brightness, and contrast of the projection symbols and projection animations, in one example, the second lens 422 can include a first optical glass, a second optical glass, a first optical resin, and a second optical resin stacked in sequence. Among them, the first optical glass faces the second lamp 421. In this way, by improving the light transmission effect of the second lens 422, the projection performance of the second lighting module 42 can be improved to ensure the picture quality such as the clarity, brightness, and contrast of the projection symbols and projection animations, that is, to ensure the display effect of the second lighting module 42.
[0054] In this example, since projections such as approach projection display are usually set as close-range projections, therefore, as Figure 7 shown, the projection display area 42a can overlap with a partial area of the first illumination display area 41a, and this overlapping area is the first overlapping area 42c. Since high-precision ADB display or high-precision DBL is usually a display effect that needs to be turned on only when the vehicle switches to high-beam illumination display, it is necessary to cooperate with high-beam illumination display. That is, the third illumination display area 42b can overlap with a partial display area of the second illumination display area 41b, and this overlapping area is the second overlapping area 42d, so as to prevent the high-beam illumination display from affecting other vehicles or personnel when the vehicle switches to high-beam illumination display, thus affecting traffic and posing a certain safety hazard problem. In this way, by setting the first overlapping area 42c and the second overlapping area 42d, it will not only not affect the display effects of each lighting display or projection display, but also can further improve the display effect through combined use.
[0055] In summary, each lighting module in the lighting display device 4 provided in the embodiments of the present application corresponds to a different display effect. Based on different display effects, zoned lighting display and projection display are realized, avoiding the problem that the display effects of some display modules affect each other, resulting in low display effects of lighting display and projection display. At the same time, the lighting display areas of lighting modules that do not affect each other can be overlapped and combined, and multiple overlapping areas can be set to further improve the display effect through coordinated use. For example, high-precision ADB display or high-precision DBL can be used in combination with high-beam lighting display. When the vehicle switches to high-beam lighting display, by combining with high-precision ADB display, it can avoid the impact of high-beam lighting display on other vehicles or personnel, thereby affecting traffic and posing a certain safety hazard. Through the lighting display device 4 of the present application, the display effect and road lighting performance of the lighting module can be improved, and the lighting reliability of the lighting module is ensured.
[0056] In one example, to achieve the switching of the display state of the second lamp 421, as Figure 8 shown, the second lighting module 42 further includes a circuit board 423. The side of the second lamp 421 away from the second lens 422 is disposed on the circuit board 423. A processor connected to the lighting controller 2 is provided on the circuit board 423, and can receive the first control signal and / or the second control signal sent by the lighting controller 2 to achieve the switching of the lighting display state or projection display of the second lamp 421.
[0057] Exemplarily, as Figure 9As shown, a processor 4231, an interface chip 4232, a transceiver 4233, a voltage regulator 4234, and a voltage converter 4235 can be integrally provided on the circuit board 423. The processor 4231 is respectively connected to the second lamp 421, the interface chip 4232, the transceiver 4233, the voltage regulator 4234, and the voltage converter 4235. Among them, the processor 4231 is used to receive signals from the interface chip 4232, the transceiver 4233, the voltage regulator 4234, and the voltage converter 4235, and control the display state of the second lamp 421 according to these signals. At the same time, the processor 4231 can also be used to detect the current temperature. Here, the current temperature refers to the ambient temperature where the vehicle is located. The processor 4231 can also determine the drive current according to the current temperature. The drive current is the current used to drive the second lamp 421 to emit light. For example, assume that the current temperature is 25 °C (degrees Celsius), which means the ambient temperature at this time is normal temperature, and the second lamp 421 can emit light normally. At this time, the drive current can be 100%. Assume that the current temperature is 70 °C (degrees Celsius), which means the ambient temperature at this time is high temperature. Then, affected by the temperature, it is necessary to reduce the drive current of the second lamp 421 to avoid the problem that the second lamp 421 cannot emit light normally due to too high temperature and too large current. At this time, the drive current can be 70%. In this way, through the processor 4231, not only can signals be received, but also the ambient temperature can be detected in real time, and the drive current can be adjusted according to the detection result to ensure the reliability of the emitted light.
[0058] Optionally, the processor 4231 can be an Application Specific Integrated Circuit (ASIC), the interface chip 4232 can be a Low-Voltage Differential Signaling (LVDS) interface, the transceiver 4233 can be a CAN transceiver, the voltage regulator 4234 can be a Low dropout regulator (LDO). The LDO has the advantages of low noise, high precision, and low voltage drop, which can improve the reliability of the LDO input and output signals. The voltage converter 4235 can be a buck converter. It can also be selected according to actual needs. In this regard, the present application does not make specific limitations.
[0059] Optionally, in order for the second lamp 421 to achieve high-precision ADB display or high-precision DBL, the second lamp 421 may include a plurality of LED particles independently controlled by a processor 4231. For example, the second lamp 421 may include 25,600 LED particles. After the processor 4231 receives different first control signals and second control signals, it can send drive current to the LEDs corresponding to the signals among the 25,600 LEDs to light up the corresponding LEDs, so that the second lamp 421 can achieve a high-precision display effect, that is, it can achieve a high-precision lighting display effect and a projection display effect.
[0060] When the second lamp 421 uses 25,600 LED particles, a large amount of heat may be generated during its operation. In order to avoid the problem that the second lamp 421 generates too much heat, causing the LEDs to be burned out or the processor 4231 to malfunction, in one example, as Figure 10 shown, the second lighting module 42 may further include a heat dissipation module 424. The heat dissipation module 424 is fixed on the circuit board 423 and is connected to the processor 4231. That is, the processor 4231 can also control the working state of the heat dissipation module 424 according to the current temperature to avoid the problem that the second lamp 421 generates too much heat, causing the LEDs to be burned out or the processor 4231 to malfunction. Here, it is worth noting that since the processor 4231 detects the ambient temperature in real time, that is, when the second lamp 421 emits light, the processor 4231 is also detecting the current temperature. The current temperature at this time may refer to the ambient temperature affected by the light emitted by the second lamp 421.
[0061] In one example, as Figure 11 shown, the heat dissipation module 424 may include a heat conducting member 4241, a heat dissipation aluminum plate 4242, and a fan 4243. The heat conducting member 4241 is fixed between one side of the circuit board 423 and the second lamp 421. One side of the heat dissipation aluminum plate 4242 is fixed on the other side of the circuit board 423, and the fan 4243 is fixed on the other side of the heat dissipation aluminum plate 4242. When the processor 4231 detects that the current temperature is too high, the processor 4231 controls the fan 4243 to start rotating to remove the heat generated by the operation of the second lamp 421, so as to avoid the problem that the second lamp 421 generates too much heat, causing the LEDs to be burned out or the processor 4231 to malfunction, thereby ensuring the display reliability of the second lamp 421.
[0062] Here, it is worth noting that the rotation speed of the fan 4243 can also be adjusted based on different current temperatures to achieve different degrees of heat dissipation. For this, it can be set according to actual needs, and the present application does not make specific limitations.
[0063] Optionally, the heat conducting member 4241 can be made of copper.
[0064] Optionally, in order to further improve the heat dissipation effect, the heat dissipation aluminum plate 4242 may be provided with a plurality of bosses.
[0065] When the vehicle is provided with the left front lighting display device 4 and the right front lighting display device 4, the projection display area 42a may also be correspondingly divided into a left projection display area and a right projection display area to further improve the display effect of the projection. For example, the left projection display area corresponding to the left front lighting display device 4 may be a symbol projection area, and the right projection display area corresponding to the right front lighting display device 4 may be a light show projection area. The left projection display area and the right projection display area may be respectively connected to the processor 4231, and the processor 4231 may control the left projection display area and the right projection display area to respectively display different projection effects through different second control signals. For example, the left projection display area may be controlled to display the vehicle logo symbol projection, and the right projection display area may be controlled to display the light show projection. In this regard, the present application does not make specific limitations.
[0066] Optionally, in order to further improve the heat dissipation effect, the heat dissipation aluminum plate 4242 may be provided with a plurality of bosses.
[0067] In one example, as Figure 12 shown, the third lighting module 43 may include a third lamp 431 and a third lens 432. The third lens 432 covers the third lamp 431. The light of the third lamp 431 forms an illumination display area in units of the third lamp 431 after passing through the third lens 432 at a preset distance, and the light of the third lamp 431 forms a fourth illumination display area 43a in units of the third lamp 431 after passing through the third lens 432 at a second preset distance B. Assuming that the third lighting module 43 is an ADB projection module at this time, the fourth illumination display area 43a corresponds to the ADB illumination display, and the display area of the fourth illumination display area 43a and the second illumination display area 41b is within the same preset distance, that is, the second preset distance B, as Figure 13 shown, the display areas of the fourth illumination display area 43a and the second illumination display area 41b overlap, and this overlapping area is the third overlapping area 43b. By setting the third overlapping area 43b, not only will it not affect the display effects of each illumination display or projection display, but also the display effect of the ADB can be further improved through combined use, that is, the combination of high-precision ADB and low-precision ADB is realized, and the display effect of the ADB is further improved.
[0068] Thus, the vehicle lighting display system provided by the embodiments of the present application can overlap and combine the lighting display areas of lighting modules that do not affect each other, and set multiple overlapping areas to further improve the display effect through combined use. For example, high-precision ADB display or high-precision DBL can be used in combination with high-beam lighting display. When the vehicle switches to high-beam lighting display, by combining with high-precision ADB display, it can avoid the high-beam lighting display from affecting other vehicles or personnel, thus affecting traffic and posing a certain safety hazard. For another example, high-precision ADB can be used in combination with low-precision ADB to improve the anti-glare effect and further avoid the high-beam lighting display from affecting other vehicles or personnel, thus affecting traffic and posing a certain safety hazard.
[0069] The embodiments of the present application further provide a vehicle, including a vehicle body and the vehicle lighting display system described in any of the above optional manners. Among them, the vehicle lighting display system includes two lighting display devices 4, and the two lighting display devices 4 are symmetrically arranged on both sides of the front part of the vehicle body.
[0070] To enrich the projection display effect, the projection display area 42a of one of the lighting display devices 4 can be a symbol projection area, and the projection display area 42a of the other lighting display device 4 can be a light show projection area. It should be understood that the vehicle provided in this embodiment includes the above vehicle control system. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding method provided above, which will not be elaborated here.
