[0002] As a key tool for traffic safety, traffic lights are widely used at intersections such as crossroads and T-junctions. They are regulated by a road traffic signal controller to guide vehicles and pedestrians to pass in an orderly manner, which is of great significance for reducing traffic accidents, improving road use efficiency, and improving traffic conditions. Traditional traffic lights mainly consist of red, green, and yellow lights, representing prohibition, permission to pass, and warning respectively, and their display states are controlled by the signal controller at the intersection.
[0003] However, the current traffic lights have limited functions and only have the characteristics of lighting on and off. Once a power outage occurs, they will immediately stop working, resulting in accidents or jams at the intersection.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.
[0032] In a first aspect, please refer to Figures 1 - 5 , some embodiments of the present application provide an environment-adaptive traffic signal light, which includes: a box body 1, a main control component 2, and a red light panel component 3, a yellow light panel component 4, and a green light panel component 5 that are installed on the box body 1 and are all electrically connected to the main control component 2; A solar sunshade 6 is provided outside the red light panel component 3 and / or the yellow light panel component 4, which is installed on the box body 1 and is electrically connected to the main control component 2; A photosensitive probe 7 for obtaining ambient brightness information is also installed on the surface of the box body 1; The main control component 2 is used to output a control scheme for the red light panel component 3, the yellow light panel component 4, and the green light panel component 5 according to the power supply situation, ambient brightness information, and pre-entered DIP switch information.
[0033] Specifically, the photosensitive probe 7 is electrically connected to the main control component 2, and the main control component 2 is also connected to the mains power supply and can monitor the power supply situation of the traffic signal light to the traffic signal. The power supply situation is divided into a normal power supply state and a power-off state regarding the mains power supply. When the power supply situation is in the power-off state, the main control component 2 continues to output a control scheme according to the ambient brightness information obtained by the photosensitive probe 7 and the pre-set DIP switch information to control the working modes of the red light panel component 3, the yellow light panel component 4, and the green light panel component 5. Thus, it is ensured that the traffic signal light can still work in the power-off state, solving the technical problem that the traffic signal light cannot work in the power-off state, resulting in potential traffic safety hazards. The solar sunshade 6 is provided outside the red light panel component 3 and / or the yellow light panel component 4 and is electrically connected to the main control component 2. The solar sunshade 6 can provide electrical energy for the traffic signal light in the power-off state, ensuring that the red light panel component 3 and / or the yellow light panel component 4 in the traffic signal light can still work in the power-off state.
[0034] More specifically, the main reason for setting the solar sunshade 6 only for the red light panel assembly 3 and / or the yellow light panel assembly 4 is that the power-off state is an abnormal state. In this case, the control scheme only controls the red light panel assembly 3 and / or the yellow light panel assembly 4 to emit light to warn traffic participants, so as to prompt traffic participants that the current environment is in an abnormal state. Therefore, there is no need for the green light panel assembly 5 to participate in emitting light.
[0035] More specifically, the photosensitive probe 7 is installed on the surface of the box body 1 to obtain ambient brightness information and provide a reference for the main control component 2 on the ambient light intensity, so that the main control component 2 can adjust the light emission intensity or light emission mode of the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5 according to the ambient brightness information, realizing environmental adaptability, so as to output different control schemes for the ambient light intensity, such as providing different control schemes for the power-off states during the day and at night. Relatively speaking, corresponding to the power-off state at night, the main control component 2 needs to provide a control scheme that is more convenient for warning traffic participants.
[0036] More specifically, in some embodiments, different DIP switch information corresponds to preset different working modes. In the power-off state, the main control component 2 outputs a control scheme according to the combination of the working mode corresponding to the DIP switch information and the light emission mode corresponding to the ambient brightness information; in some other embodiments, the DIP switch information corresponds to preset multiple working modes matching different ambient brightness information. In the power-off state, the main control component 2 selects one of the multiple working modes corresponding to the DIP switch information according to the ambient brightness information to output a control scheme.
[0037] More specifically, the photosensitive probe 7 can select photosensitive devices such as silicon photovoltaic cells or photoresistors, and is installed on the top of the box body 1 to ensure that it is not blocked by the solar sunshade 6 and to monitor the ambient light intensity in real time.
[0038] It should be noted that in the normal power supply state, the main control component 2 preferentially uses the mains power supply and outputs a preset normal light emission scheme to control the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5 to work according to the preset traffic signal timing.
[0039] The environment-adaptive traffic signal lamp of the embodiment of the present application can output control schemes for the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5 according to the power supply situation, the ambient brightness information and the pre-input DIP switch information, so as to control the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5 to work according to the preset traffic signal timing in the normal power supply state, and use solar power generation to control the red light panel assembly 3 and / or the yellow light panel assembly 4 to emit light to warn traffic participants to pay attention to safety in the power-off state. Even in the event of a sudden power failure, the basic traffic order at the intersection can still be maintained, and the probability of traffic accidents can be reduced.
[0040] In some preferred embodiments, the box body 1 includes a housing 11 and a front frame 12 mounted on the front of the housing 11. The red light panel assembly 3, the yellow light panel assembly 4, the green light panel assembly 5, and the photosensitive probe 7 are all mounted on the front frame 12.
[0041] Specifically, as Figure 3 shown, there are multiple front frames 12. One end of each front frame is hinged to the box body 1, and the other end is mounted on the box body 1 by buckling or locking, which facilitates maintenance personnel to unlock and open the front frame 12 for overhauling the inside of the environment-adaptive traffic signal lamp.
[0042] More specifically, each front frame 12 corresponds to and mounts a light panel assembly, which facilitates maintenance personnel to unlock and open the front frame 12 for independently overhauling each light panel assembly in the environment-adaptive traffic signal lamp.
[0043] In some preferred embodiments, the red light panel assembly 3, the yellow light panel assembly 4, and the green light panel assembly 5 all include: a lamp bowl 31, mounted on the box body 1; a lamp shade 32, mounted on the lamp bowl 31; a light-emitting plate member 33, mounted between the lamp bowl 31 and the lamp shade 32.
[0044] Specifically, the lamp bowl 31 is mounted on the surface of the box body 1 and used as the basic support structure of the light panel assembly. Its shape can be designed as a cylindrical shape, a frustum shape, or a multi-pyramid frustum shape to facilitate the installation and fixation of internal components.
[0045] More specifically, the lamp shade 32 is mounted above the lamp bowl 31 and forms a connection relationship with the lamp bowl 31, thereby protecting the internal light-emitting plate member 33 from being eroded by external environmental factors. In the embodiments of the present application, the lamp shade 32 is preferably a transparent cover without patterns to ensure that the light emitted by the light-emitting plate member 33 can effectively penetrate through and realize the signal indication function.
[0046] More specifically, the light-emitting plate member 33 is mounted inside the cavity formed by the lamp bowl 31 and the lamp shade 32 and serves as the core component for generating traffic signal lights. The light-emitting plate member 33 can be a printed circuit board, on which light-emitting devices, such as LED lamp beads, are arranged for emitting different colors of light, such as red, yellow, and green.
[0047] More specifically, the lamp bowl 31 and the lamp shade 32 can be quickly installed and fixed through a buckle structure. The light-emitting plate member 33 is fixed at a specific position inside the lamp bowl 31 by screws or buckles, and the lamp bowl 31 can be fixed on the box body 1 by screws.
[0048] More specifically, through the structural cooperation of the lamp bowl 31, the lamp cover 32 and the light-emitting plate member 33, the overall structural strength and protection performance of the lamp panel assembly are improved. The lamp bowl 31 serves as a support, providing a stable installation platform for the light-emitting plate member 33 and the lamp cover 32. The lamp cover 32 is like a protective shell, sealing the light-emitting plate member 33 in the internal space, effectively isolating external impurities such as dust and rainwater, and preventing the light-emitting plate member 33 from being corroded or damaged. Thus, the reliable operation of the lamp panel assembly under various harsh weather conditions is ensured, and the service life of the traffic signal lamp is extended.
[0049] In some preferred embodiments, the main control assembly 2 includes a power conversion board 21, a power supply battery pack 22 and a control panel 23 provided in each lamp bowl 31. The light-emitting plate member 33 and the power conversion board 21 are both electrically connected to the control panel 23, and the power supply battery pack 22 is electrically connected to the power conversion board 21.
[0050] Specifically, the power conversion board 21 can convert the electrical energy provided by an external power source (mains electricity) or the solar canopy 6 into the voltage required by electronic components such as the light-emitting plate member 33 and the control panel 23, providing stable power supply for the normal operation of the traffic signal lamp, and being able to charge and discharge the power supply battery pack 22; the power supply battery pack 22 can provide backup power support for the traffic signal lamp in the case of a power outage of the external power source, ensuring that the traffic signal lamp can still continue to work under abnormal conditions such as a power outage, improving reliability, and the solar canopy 6 can charge the power supply battery pack 22 under the conversion action of the power conversion board 21; the control panel 23 is the core control component of the traffic signal lamp, receiving, processing and executing various control instructions. For example, the lighting, color switching, flashing frequency, etc. of the light-emitting plate member 33 are controlled by the control panel 23 to realize various display functions and modes of the traffic signal lamp; by integrating the power conversion board 21, the power supply battery pack 22 and the control panel 23 inside the lamp bowl 31, the structure of the main control assembly 2 is more compact, the volume is smaller, the installation and maintenance are easier, and at the same time, the external wiring between components is reduced, the integration degree and reliability of the system are improved, and the space utilization rate of the lamp bowl 31 is increased.
[0051] It should be noted that the power conversion board 21 is also connected to the mains power supply terminal.
[0052] In a further embodiment, the power supply battery pack 22 is only provided in the lamp bowls 31 of the red lamp panel assembly 3 and the yellow lamp panel assembly 4.
[0053] In some preferred embodiments, the box body 1 is provided with a wire passing hole 13, and the lamp bowl 31 is provided with a wire outlet hole 311. The solar canopy 6 is electrically connected to the power conversion board 21 through a connecting wire 8 passing through the wire passing hole 13 and the wire outlet hole 311.
[0054] Specifically, the connecting wire 8 orderly passes through the wire passing hole 13 on the box body 1 and the wire outlet hole 311 on the lamp bowl 31 to realize the electrical connection between the solar awning 6 and the power conversion board 21, enabling the connecting wire 8 to pass through the box body 1 and the lamp bowl 31 along the shortest path, reducing the length and loss of the circuit. To improve the protection performance, sealing rings can be provided at the edges of the wire passing hole 13 and the wire outlet hole 311 to prevent dust and moisture from entering the interior of the box body 1 and the lamp bowl 31.
[0055] In some preferred embodiments, the lamp bowl 31 is tapered in a multi-pyramid shape, the power conversion board 21 and the power supply battery pack 22 are installed on the inner side of the tapered end of the lamp bowl 31, and a groove 312 is provided on the inner side of one tapered side of the lamp bowl 31, and the control panel 23 is installed in the groove 312.
[0056] Specifically, the multi-pyramid shape causes the lamp bowl 31 to gradually narrow from the open end to the end, and the power conversion board 21 and the power supply battery pack 22 are installed on the inner side of the tapered end inside the lamp bowl 31, that is, the inner space of the narrowest part of the lamp bowl 31. The control panel 23 is installed in the groove 312, that is, the groove 312 is used to position and fix the control panel 23. Thus, the inner space of the lamp bowl 31 is effectively utilized, the installation positions of the components are more standardized and concentrated, and the fixing of the control panel 23 is also enhanced.
[0057] More specifically, in this embodiment, the lamp bowl 31 is no longer a traditional cylindrical or other regular shape, but adopts a tapered multi-pyramid design, which makes a gradually narrowing space formed inside the lamp bowl 31. When installing the main control component 2, the two components with relatively large volumes, namely the power conversion board 21 and the power supply battery pack 22, are placed in the inner space of the tapered end of the lamp bowl 31, that is, the relatively concentrated area at the bottom of the lamp bowl 31, which can save the inner space of the lamp bowl 31 and improve the stability of the signal lamp. During installation, the control panel 23 is embedded and fixed in the groove 312 to use the groove 312 to limit and support the control panel 23, prevent the control panel 23 from loosening or shifting inside the lamp bowl 31, ensure the stability and reliability of the installation of the control panel 23, and at the same time create a middle gap to cool down the main heat-generating components (the light-emitting board 33, the power conversion board 21, and the power supply battery pack 22).
[0058] In some preferred embodiments, the light-emitting board 33 includes a lamp board 331 and a character lamp bead board 332.
[0059] Specifically, as Figure 4 shown, in the embodiment of the present application, the light-emitting board 33 is preferably composed of a lamp board 331 and a character lamp bead board 332. Among them, the lamp board 331 is used to generate uniformly distributed light, and the character lamp bead board 332 is used to generate light about specific characters, such as the light in the shape of the character "slow", to meet the warning requirements of various scenarios.
[0060] More specifically, the lamp board 331 can be implemented as a functional component that provides the basic light-emitting display of traffic lights. For example, it can adopt a surface light source light-emitting component for emitting light rays of indicating colors such as red, yellow, and green to achieve the indicating function of traditional traffic lights. The character lamp bead board 332 can be implemented as a functional component capable of displaying characters, numbers, or specific patterns, and can be composed of dot matrix LED lamp beads. By controlling the lighting and extinguishing of the dot matrix LED lamp beads, character information can be displayed. The control panel 23 can respectively control the working states of the lamp board 331 and the character lamp bead board 332, enabling the two to work together to display a composite traffic signal that includes both color signals and character information.
[0061] More specifically, by adopting the design of the light-emitting plate member 33 that combines the lamp board 331 and the character lamp bead board 332, the functional diversity of the light-emitting plate member 33 is enhanced, and the information transmission efficiency and practicality of the traffic lights are also improved accordingly.
[0062] In some preferred embodiments, the control scheme includes a light-emitting mode in the power-off state. The DIP information is set or adjusted based on a DIP switch (not shown in the figure) connected to the control panel 23. The control panel 23 stores multiple light-emitting modes in the power-off state that match different DIP information and ambient brightness information.
[0063] Specifically, the light-emitting mode in the power-off state is pre-programmed and stored in the memory of the control panel 23, and the DIP information is set through an external DIP switch; when the DIP information needs to be adjusted, maintenance personnel can change the DIP information by toggling the DIP switch to adjust the corresponding light-emitting mode in the power-off state.
[0064] More specifically, the DIP switch is installed inside the inspection hole at the bottom of the box body 1, and maintenance personnel can insert a special screwdriver into the inspection hole to toggle the DIP switch to achieve the switching of the display effect of the lamp panel.
[0065] More specifically, the control panel 23 stores multiple light-emitting modes, and each mode matches specific DIP information and ambient brightness information. The ambient brightness information is detected in real time by the photosensitive probe 7. The control panel 23 receives the signal from the photosensitive probe 7, judges the current ambient brightness level, and selects the corresponding light-emitting mode in the power-off state from the memory in combination with the DIP information set by the DIP switch. In this way, even in the case of power failure, the traffic lights can automatically switch to a suitable light-emitting mode according to the environmental conditions to maintain the traffic warning function.
[0066] In some preferred embodiments, the red lamp panel assembly 3, the yellow lamp panel assembly 4, and the green lamp panel assembly 5 are arranged vertically downward in sequence on the box body 1, and a first eaves 9 is installed on the box body 1 outside the green lamp panel assembly 5.
[0067] Specifically, the first eaves 9 is an ordinary eaves without the function of solar power generation.
[0068] More specifically, the shapes of the solar eaves 6 and the first eaves 9 can be an arc structure with the top extending outwards, or a flat structure sloping downwards, ensuring that the eaves can effectively block stray light from above and the sides. The solar eaves 6 and the first eaves 9 are fixed to the box body 1 by means of screws, buckles or bonding, etc., ensuring the firmness and reliability of the installation.
[0069] More specifically, the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5 are arranged in a vertically downward order, which conforms to the conventional setting habit of traffic lights and is easy to be observed and recognized. At the same time, the solar eaves 6 outside the red light panel assembly 3 and the yellow light panel assembly 4 located above are also easier to collect sunlight for power supply.
[0070] In some preferred embodiments, the installation height of the photosensitive probe 7 is higher than the highest point of the solar eaves 6.
[0071] Specifically, in order to avoid the solar eaves 6 blocking the photosensitive probe 7, the installation position of the photosensitive probe 7 is set to be higher than the highest point of the solar eaves 6. Thus, even if the sunlight irradiates at a lower angle, the solar eaves 6 will not form a shadow above the photosensitive probe 7. The photosensitive probe 7 can more directly sense the ambient light intensity, thereby obtaining the ambient brightness information more accurately.
[0072] More specifically, the photosensitive probe 7 can continuously and accurately collect ambient brightness data. After receiving these accurate ambient brightness information, the main control component 2 can more reasonably adjust the light emission intensity or mode of the red light panel assembly 3, the yellow light panel assembly 4 and the green light panel assembly 5. Therefore, the ambient adaptability performance and reliability of the traffic light are improved, and traffic safety can be effectively guaranteed.
[0073] In a second aspect, please refer to Figure 6 , some embodiments of the present application further provide a control method for an ambient adaptive traffic light, which is applied to an ambient adaptive traffic light. The ambient adaptive traffic light includes: a box body 1, a red light panel assembly 3, a yellow light panel assembly 4 and a green light panel assembly 5 installed on the box body 1; a solar eaves 6 installed on the box body 1 is provided outside the red light panel assembly 3 and / or the yellow light panel assembly 4; a photosensitive probe 7 for obtaining ambient brightness information is further installed on the surface of the box body 1; The control method includes the following steps: S1. Obtain and analyze the current power supply situation. When the power supply situation is in a normal power supply state, output a preset normal light emission scheme. When the power supply situation is in a power-off state, execute step S2; S2. Output a control solution for the red light panel assembly 3, yellow light panel assembly 4, and green light panel assembly 5 according to the environmental brightness information and pre-input DIP switch information.
[0074] Specifically, in step S1, the acquisition of the power supply situation can be achieved by using components such as a voltage sensor or a current sensor to monitor the voltage or current value of the power line in real time. In the normal power supply state, the traffic signal lights work according to the preset time sequence and mode. For example, a standard alternating flashing scheme of red, green, and yellow lights can be adopted. When the system detects a power-off state, it will automatically switch to step S2.
[0075] More specifically, in step S2, the environmental brightness information is collected in real time by the photosensitive probe 7. The photosensitive probe 7 can be selected from a photosensitive resistor, a photosensitive diode, or a photoelectric sensor, etc. These devices can convert the environmental light intensity into an electrical signal for the main control component 2 to analyze and process. The DIP switch information is set in advance through a DIP switch and is used for users to preset different control modes according to actual needs. The main control component 2 searches for the pre-stored control solution according to the environmental brightness information collected by the photosensitive probe 7 and the DIP switch information set by the DIP switch, and outputs the corresponding control signal to control the light-emitting states of the red light panel assembly 3, yellow light panel assembly 4, and green light panel assembly 5. Thus, even in the case of a power failure, the traffic signal lights can provide corresponding warning or indication functions using solar power supply according to the environmental brightness and preset mode, reducing potential safety hazards.
[0076] The control method of the environment-adaptive traffic signal light in the embodiment of the present application can output a control solution for the red light panel assembly 3, yellow light panel assembly 4, and green light panel assembly 5 according to the power supply situation, environmental brightness information, and pre-input DIP switch information, so as to control the red light panel assembly 3, yellow light panel assembly 4, and green light panel assembly 5 to work according to the preset traffic signal light time sequence in the normal power supply state, and use solar power generation to control the red light panel assembly 3 and / or yellow light panel assembly 4 to emit light to warn traffic participants to pay attention to safety in the power-off state. In this way, the environment-adaptive traffic signal light can still provide effective traffic safety protection according to the environmental conditions and preset mode in the case of a power failure, solving the problem that traditional signal lights fail when the power is off.
[0077] In some preferred embodiments, solar canopies 6 are installed on the box body 1 outside both the red light panel assembly 3 and the yellow light panel assembly 4. When the character lamp bead board 332 is lit, the character "slow" is displayed. In the power-off state, the relationship between the DIP switch information, environmental brightness information, and the control solution is as follows: 1) When the DIP switch information is 0, regardless of the environmental brightness information, the control solution is: the yellow light panel assembly 4 and the red light panel assembly 3 remain in the extinguished state; 2) When the DIP switch information is 1, regardless of the ambient light intensity information, the control scheme is as follows: the lamp board 331 of the yellow lamp panel assembly 4 alternately lights up for 1 second and then extinguishes for 1 second. At the same time, the character lamp beads board 332 of the red lamp panel assembly 3 alternately lights up for 1 second and then extinguishes for 1 second. When the character lamp beads board 332 is lit, the character "slow" is displayed.
[0078] 3) When the DIP switch information is 2, regardless of the ambient light intensity information, the lamp board 331 of the yellow lamp panel assembly 4 alternately lights up for 1 second and then extinguishes for 1 second, and the red lamp panel assembly 3 remains extinguished.
[0079] 4) When the DIP switch information is 3, if the analysis result of the ambient light intensity information (determined by classification based on a preset brightness threshold) is daytime, the lamp board 331 of the yellow lamp panel assembly 4 alternately lights up for 1 second and then extinguishes for 1 second. At the same time, the character lamp beads board 332 of the red lamp panel assembly 3 alternately lights up for 1 second and then extinguishes for 1 second. If the analysis result of the ambient light intensity information is nighttime, the lamp board 331 of the yellow lamp panel assembly 4 alternately lights up for 1 second and then extinguishes for 1 second. At the same time, the character lamp beads board 332 of the red lamp panel assembly 3 remains lit.
[0080] 5) When the DIP switch information is 4, regardless of the ambient light intensity information, the lamp board 331 of the yellow lamp panel assembly 4 remains lit, and the red lamp panel assembly 3 remains extinguished.
[0081] 6) When the DIP switch information is 5, regardless of the ambient light intensity information, the character lamp beads board 332 of the red lamp panel assembly 3 remains lit, and the yellow lamp panel assembly 4 remains extinguished.
[0082] 7) When the DIP switch information is 6, regardless of the ambient light intensity information, the lamp board 331 of the yellow lamp panel assembly 4 remains lit, and the character lamp beads board 332 of the red lamp panel assembly 3 remains lit.
[0083] 8) When the DIP switch information is 7, regardless of the ambient light intensity information, the lamp board 331 of the yellow lamp panel assembly 4 remains lit, and the character lamp beads board 332 of the red lamp panel assembly 3 alternately lights up for 1 second and then extinguishes for 1 second.
[0084] 9) When the DIP switch information is 8, regardless of the ambient light intensity information, the lamp board 331 of the yellow lamp panel assembly 4 alternately lights up for 1 second and then extinguishes for 1 second, and the character lamp beads board 332 of the red lamp panel assembly 3 remains lit.
[0085] In the above embodiments, when the DIP switch information is set to 3, the control method of the environment-adaptive traffic signal lamp in the embodiment of the present application can, in the power-off state, control the yellow lamp panel assembly 4 and the red lamp panel assembly 3 to execute different lighting modes for daytime and nighttime. Among them, during the day, the character lamp beads board 332 of the red lamp panel assembly 3 alternately lights up for 1 second and then extinguishes for 1 second, and at night, the character lamp beads board 332 of the red lamp panel assembly 3 remains lit, which can effectively enhance the warning ability at night.
