Description

Technical Field

[0001] The present application relates to the field of lighting control technology, and in particular to a lighting fixture control method, a lighting fixture, and an electronic device. Background Art

[0002] As an essential component of modern transportation networks, tunnels have significantly improved road alignment and reduced driving distances. However, as semi-enclosed spaces, tunnels present significant differences in light conditions between the interior and exterior, creating a host of unique traffic safety issues.

[0003] Currently, most tunnels utilize fixed-intensity lighting fixtures. This lighting method has a significant drawback: the illumination level it provides is constant and cannot adapt to the dynamic fluctuations in natural light intensity outside the tunnel. During the day, especially under clear skies and strong sunlight, the brightness outside the tunnel is extremely high, while the brightness inside the tunnel is relatively low. When a driver suddenly enters the tunnel from a brighter environment to a darker one, the human eye takes a while (approximately 5-10 seconds) to adjust to the dramatic change in light intensity. This phenomenon is known as "adaptation lag." During this brief adaptation period, the driver experiences a temporary "black hole" effect, making it difficult to clearly discern road conditions, obstacles, or other vehicles within the tunnel, which can easily lead to traffic accidents such as rear-end collisions and collisions. Conversely, at dusk or dawn, the brightness outside the tunnel drops rapidly, potentially falling below the fixed illumination level inside the tunnel. When a vehicle exits the tunnel, the driver enters a darker environment from a relatively bright one, creating a "white hole" effect that also results in a temporary visual blind spot, posing a safety hazard.

[0004] Therefore, the fixed-intensity tunnel lighting method used in related technologies struggles to dynamically and intelligently adapt to changes in the tunnel's internal and external lighting environments. This approach fails to fundamentally address drivers' visual adaptation issues, posing a potential risk to road safety. An intelligent control method is urgently needed that can automatically and smoothly adjust tunnel lighting intensity based on the external ambient brightness to eliminate visual disparity and ensure driving safety.

[0041] The following combination Figures 1 to 5 The present invention describes a lighting fixture control method, a lighting fixture, and an electronic device.

[0042] According to the embodiment of the first aspect of the present application, Figure 1 As shown, the lighting fixture includes a lighting unit and a detection unit, the lighting unit is used to be installed in a tunnel, the lighting unit is used to adjust the light intensity in the tunnel, and the detection unit is used to be installed outside the tunnel, the detection unit is used to detect the light intensity outside the tunnel; the control method includes:

[0043] Step 101: Acquire the current light intensity inside the tunnel and the current light intensity outside the tunnel;

[0044] It is understandable that the light intensity inside the tunnel and the light intensity outside the tunnel can be detected by a light intensity detection sensor to determine the current light intensity data inside the tunnel and the current light intensity data outside the tunnel.

[0045] Step 102: Determine whether a difference between a current light intensity inside the tunnel and a current light intensity outside the tunnel is greater than a threshold;

[0046] It is understandable that when the difference between the current light intensity inside the tunnel and the current light intensity outside the tunnel is greater than the threshold, it means that the difference in light intensity inside and outside the tunnel is too large. When the driver enters the tunnel from outside or leaves the tunnel from inside, the human eye needs a certain amount of time to adapt to the change in light intensity, which poses a safety hazard.

[0047] Step 103: Control the lighting unit to adjust the light intensity in the tunnel so that the difference between the current light intensity in the tunnel and the current light intensity outside the tunnel is less than a threshold.

[0048] It can be understood that when it is determined that the difference between the current light intensity in the tunnel and the current light intensity outside the tunnel is greater than a threshold value, the lighting unit is controlled to adjust the light intensity in the tunnel so that the difference between the light intensity in the tunnel and the light intensity outside the tunnel is less than the threshold value. Then, when the driver enters and exits the tunnel, the human eye can quickly adapt to environmental changes, and there will be no short-term visual blind spots, thereby ensuring driving safety.

[0049] The lighting fixture control method of the embodiment of the present application dynamically adjusts the light intensity inside the tunnel to keep it coordinated with the light intensity of the external environment, thereby eliminating or significantly reducing the visual discomfort and safety hazards caused by the sudden changes in light and dark when the driver enters and exits the tunnel.

[0050] It should be noted that the detection unit is at least used to detect the light intensity at the tunnel entrance, and the lighting unit is at least used to adjust the light intensity at the tunnel entrance.

[0051] In some embodiments, the step of controlling the lighting unit to adjust the light intensity in the tunnel includes:

[0052] When it is determined that a vehicle is traveling from outside the tunnel to inside the tunnel, or when it is determined that a vehicle is traveling from inside the tunnel to outside the tunnel,

[0053] The lighting unit is controlled to adjust the light intensity in the tunnel.

[0054] It is understandable that before controlling the lighting unit to adjust the light intensity in the tunnel, it is necessary to first determine whether there is a vehicle traveling from outside the tunnel to inside the tunnel or from inside the tunnel to outside the tunnel. That is, when there is a vehicle entering or exiting the tunnel, the lighting unit is controlled to adjust the light intensity in the tunnel. When there is no vehicle entering or exiting the tunnel, the light intensity in the tunnel is not adjusted, which is beneficial to saving energy consumption.

[0055] In some embodiments, the current light intensity in the tunnel is less than the current light intensity outside the tunnel, the lighting unit includes a plurality of lighting elements, and the plurality of lighting elements are evenly distributed along the length of the tunnel; and the step of controlling the lighting unit to adjust the light intensity in the tunnel includes:

[0056] determining a real-time position of a cab of the vehicle within the tunnel;

[0057] Determining a target lighting component based on the real-time position, where the distance between the target lighting component and the cab of the vehicle is less than a preset value;

[0058] The target lighting element is controlled to operate so that a difference between the light intensity at the cab of the vehicle and the current light intensity outside the tunnel is smaller than a threshold.

[0059] It is understandable that, while the driver is in the cab, driving safety can be guaranteed by simply ensuring that the light intensity at the cab does not significantly change. Therefore, when controlling the lighting unit to adjust the light intensity in the tunnel, this embodiment first determines the real-time position of the vehicle's cab within the tunnel. Based on the real-time position of the cab, it then identifies lighting components near the cab as target lighting components. The target lighting components are then controlled to adjust the light intensity at the cab so that the difference between the light intensity at the cab and the light intensity outside the tunnel is less than a threshold value, thereby ensuring driving safety while saving energy.

[0060] It should be noted that there can be multiple target lighting elements.

[0061] It is understandable that the target lighting component is not fixed, but a new target lighting component is continuously determined according to the position change of the cab.

[0062] In some examples, the lighting section is composed of multiple independently controllable lighting elements (such as individual LED modules or lamps) that are evenly distributed along the length of the tunnel, particularly at the entrance, to form a high-resolution lighting matrix.

[0063] In some cases, devices for real-time vehicle position tracking can be added. For example, a high-precision ranging radar array or video image processing unit can be installed on the top or side walls of the tunnel entrance. These sensors can continuously detect the position of vehicles within the tunnel, specifically accurately locating the height and longitudinal distance of their cabs, converting the "real-time vehicle position" into data that can be processed by the control unit.

[0064] The working principle of this embodiment is based on spatial positioning and dynamic following. The system no longer dims the tunnel entrance as a whole, but divides it into many small areas controlled by independent lighting components. When the system determines that the external light is stronger and a vehicle is entering: it continuously obtains the precise position of the vehicle cab in the tunnel, and predicts its forward path in a short period of time based on the vehicle's current position and speed. It only activates and brightens the most relevant lighting components (i.e., target lighting components) in front of the vehicle and directly above the cab, creating a "local light island" within the driver's field of view, with brightness coordinated with the external environment. As the vehicle travels into the tunnel, the system controls the target lighting components to light up and go out in sequence, forming a "light wave" that follows the vehicle forward, always ensuring that the road brightness in front of the driver is sufficient, ensuring that the enhanced light is just used by the driver, and greatly avoiding the waste of lighting resources.

[0065] Specifically, the control unit receives data streams from a positioning detection unit (such as radar) and uses a built-in algorithm to calculate and output the precise position of the vehicle's cab within the tunnel (usually expressed in meters from the tunnel entrance) in real time. This process is continuous to ensure the timeliness and accuracy of the position.

[0066] The control unit pre-stores the installation position information of each lighting component in the entire lighting matrix. The system compares the real-time position of the vehicle with the positions of all lighting components. The spatial distance between the vehicle cab and each lighting component is calculated, and these distances are compared with the preset distance values ​​pre-set in the system. All lighting components with a distance less than the preset value (this "preset value" is a radius parameter set according to optical characteristics to ensure that the illuminated lighting components are sufficient to cover the driver's field of view and form a smooth light transition. The target lighting component is usually a local lighting component group in front centered on the current position of the vehicle) are determined as the target lighting components that currently need to be controlled.

[0067] The control unit generates specific control instructions and sends them to the target lighting components determined in the previous step, instructing them to increase their power and brightness. Other lighting components in the tunnel maintain basic lighting or a lower power state. The difference between the light intensity at the location of the vehicle's cab (the brightness actually perceived by the driver) and the current light intensity outside the tunnel is made less than the safety threshold. As the vehicle continues to move inward, its "real-time position" is continuously updated, and the system dynamically updates the set of "target lighting components". The lighting components that have been passed by the vehicle are dimmed, while the lighting components in front of the vehicle are brightened one by one, forming a moving light spot that always guides the driver forward safely.

[0068] Through real-time vehicle positioning and coordinated control of the lighting matrix, precise follow-up lighting is achieved: "light intensity increases when the vehicle approaches, and decreases when the vehicle leaves." This not only effectively eliminates visual blind spots but also strictly controls energy consumption to only provide power where and when it's needed, significantly optimizing safety and energy efficiency.

[0069] In some embodiments, the step of determining the real-time position of the cab of the vehicle in the tunnel comprises:

[0070] Acquiring the positioning data of the vehicle and the length parameters of the vehicle;

[0071] Based on the positioning data of the vehicle and the length parameter of the vehicle, a real-time position of the cab of the vehicle is determined.

[0072] It is understandable that when a vehicle (such as a subway or a large truck) is long, the positioning of the vehicle can only represent the position of the entire vehicle and cannot accurately determine the position of the vehicle's cab.

[0073] Therefore, this embodiment introduces the length parameter of the vehicle. Combined with the vehicle positioning data and the vehicle length parameter, the real-time position of the vehicle's cab can be accurately determined, and then the target lighting components can be accurately determined to ensure that the light intensity in the cab does not change significantly.

[0074] In some examples, a camera can capture a vehicle image, using a deep learning model to identify the vehicle's make and model, and then query the standard length data for that model from a pre-set vehicle model database. High-precision radar can also be used to scan the vehicle's shape and directly estimate its real-time length. The system can also directly receive the vehicle's own attribute parameters transmitted via communication, including vehicle length.

[0075] In some examples, the calculation formula is: real-time cab position = vehicle front position - (total vehicle length × proportional coefficient K). The proportional coefficient K is an empirical value (for example, for a car with a cab located at the front, the K value may be 0.2, indicating that the cab is approximately 20% of the front of the vehicle).

[0076] Exemplarily, a signal is received from a positioning data acquisition unit (such as a radar) to obtain the positioning data of the vehicle. For example, the data returned by the radar is "the front end (front end) of the vehicle is 15 meters away from the tunnel entrance", and a signal is received from a vehicle parameter acquisition unit (such as a vehicle type recognition system) to obtain the length parameter of the vehicle. For example, the system recognizes that the current vehicle is a mid-size sedan, and finds from the database that its standard length is 4.8 meters. The control unit has built-in calculation logic (algorithm), and substitutes the above two data into a predetermined calculation formula to determine the precise position of the cab (cab position = 15 meters - (4.8 meters × 0.2) = 15 meters - 0.96 meters ≈ 14.04 meters, indicating that the actual position of the vehicle cab is about 14.04 meters inward from the tunnel entrance. This position is the target area that the lighting system needs to focus on and adjust).

[0077] In some embodiments, the lighting unit includes a first lighting group and a second lighting group, the first lighting group includes a plurality of first lighting elements, the plurality of first lighting elements are sequentially distributed along the direction from the entrance of the tunnel to the exit of the tunnel, and the plurality of first lighting elements are evenly distributed between the entrance of the tunnel and the middle position of the tunnel, the second lighting group includes a plurality of second lighting elements, the plurality of second lighting elements are sequentially distributed along the direction from the exit of the tunnel to the entrance of the tunnel, and the plurality of second lighting elements are evenly distributed between the middle position of the tunnel and the exit of the tunnel; the step of controlling the lighting unit to adjust the light intensity in the tunnel includes:

[0078] determining that a current light intensity outside the tunnel is greater than a current light intensity inside the tunnel;

[0079] controlling the plurality of first lighting elements so that a difference between light intensity at the entrance of the tunnel and light intensity outside the tunnel is less than a threshold value, and the light intensity inside the tunnel gradually decreases from the entrance of the tunnel to a middle position of the tunnel;

[0080] The plurality of second lighting elements are controlled so that a difference between light intensity at the exit of the tunnel and light intensity outside the tunnel is smaller than a threshold value, and the light intensity in the tunnel gradually increases from the middle position of the tunnel to the exit of the tunnel.

[0081] It can be understood that when it is determined that the light intensity outside the tunnel is greater than the light intensity inside the tunnel, multiple first lighting components are controlled, and the closer the first lighting components are to the entrance of the tunnel, the greater the light intensity emitted, so that the difference between the light intensity at the entrance of the tunnel and the light intensity outside the tunnel is less than the threshold value, and the light intensity in the tunnel gradually decreases from the entrance of the tunnel to the middle position of the tunnel, so that when the driver enters the tunnel from the outside, he can gradually adapt to the light intensity in the tunnel, and there will be no sudden and drastic changes in light intensity that will cause the driver to be unable to effectively identify the road conditions ahead, thereby ensuring driving safety. At the same time, it can also avoid the waste of energy caused by all the first lighting components emitting high-intensity light, which is conducive to reducing energy consumption.

[0082] Multiple second lighting elements are controlled simultaneously, with the closer the first lighting element is to the tunnel exit, the greater the light intensity it emits. This ensures that the difference between the light intensity at the tunnel exit and the light intensity outside the tunnel is less than a threshold, and the light intensity inside the tunnel gradually increases from the middle of the tunnel to the tunnel exit. When a driver exits the tunnel, they experience the gradually increasing light intensity, allowing them to quickly adapt to the light intensity outside the tunnel. This prevents sudden, drastic changes in light intensity that could prevent the driver from effectively identifying the road ahead, ensuring driving safety. This also avoids energy waste caused by all second lighting elements emitting high-intensity light, thereby reducing energy consumption.

[0083] In some examples, the first lighting group is responsible for lighting the tunnel entrance section. The first lighting group includes a plurality of first lighting components (such as dimmable LED lamps). These first lighting components are installed sequentially from the tunnel entrance along the direction of travel (from the entrance to the exit) and are evenly distributed on the top wall or side wall between the tunnel entrance and the middle position of the tunnel (or the "starting point of the transition section"). The second lighting group is responsible for lighting the tunnel exit section. The second lighting group includes a plurality of second lighting components. These second lighting components are installed sequentially from the tunnel exit against the direction of travel (from the exit to the entrance) and are evenly distributed on the top wall or side wall between the middle position of the tunnel and the tunnel exit.

[0084] Understandably, when the light intensity outside the tunnel is greater than that inside (typically during daylight hours), the primary risk is a "black hole effect" at the entrance. The system controls the first lighting group to create a high-to-low brightness ramp at the entrance. Specifically, the luminaires closest to the entrance are at their highest brightness (closest to the bright external light). As drivers travel deeper into the tunnel, the brightness gradually or smoothly decreases until it matches the baseline illumination level in the tunnel's middle section. This ensures that drivers experience a gradually decreasing brightness upon entering the tunnel, rather than a sudden drop, giving the eye ample time to adapt. When the light intensity outside the tunnel is less than that inside (typically at dusk or night), the primary risk is a "white hole effect" or visual blind spot at the exit. The system controls the second lighting group to create a low-to-high brightness ramp at the exit. Specifically, starting in the middle of the tunnel and moving toward the exit, the luminaires gradually or smoothly increase in brightness, bringing the exit's brightness closer to that of the dimly lit environment. In this way, when the driver exits the tunnel, his eyes have already adapted to the darker light in advance, avoiding momentary visual failure caused by suddenly entering a dark environment.

[0085] The control unit continuously compares the current light intensity inside and outside the tunnel. When it is determined that the current light intensity outside the tunnel is greater than the current light intensity inside the tunnel:

[0086] Based on the significant light intensity outside the tunnel, the control unit calculates a high target brightness value and commands the first primary lighting fixture closest to the tunnel entrance to operate at this high brightness. Subsequently, the system calculates a gradually decreasing brightness value for each subsequent primary lighting fixture based on a preset gradient algorithm. The control unit then sends instructions to each primary lighting fixture in the sequence, adjusting its brightness according to the calculated value. Ultimately, a continuously and smoothly decreasing brightness curve is formed in physical space, from the tunnel entrance (brightest) to the middle of the tunnel (consistent with the internal baseline brightness), perfectly guiding the driver's vision to adapt to the tunnel's internal environment.

[0087] Due to the strong external light intensity, the exit requires higher brightness to match. The control unit calculates a progressive brightness curve from the middle position to the exit. It controls all secondary lighting elements in the second lighting group, starting at the middle position (consistent with the internal baseline brightness) and gradually increasing in brightness toward the exit, ultimately bringing the brightness at the exit to a level that harmonizes with the external environment. This way, as the vehicle moves from the interior toward the exit, the vehicle's vision also experiences a gradual brightness change, preparing for the impending exit into a brightly lit environment.

[0088] It is understandable that when the system determines that the light intensity outside the tunnel is less than that inside the tunnel (at night), the above process will be reversed: the first lighting group can maintain a lower brightness or be turned off, while the second lighting group will work to create a decreasing brightness gradient from the inside of the tunnel (brighter) to the exit (darker) to deal with the risks when exiting.

[0089] In some embodiments, the control method further includes:

[0090] Get real-time weather data and time data;

[0091] The threshold is dynamically adjusted based on the real-time weather data and time data.

[0092] It is understandable that the "threshold" is not a fixed value, but an adaptive parameter that is dynamically adjusted according to the environmental conditions outside the tunnel to cope with the differences in the human eye's adaptability in different weather and time periods.

[0093] The control unit obtains real-time weather forecast information (such as visibility, rainfall, and snowfall) through an internet interface or directly obtains localized weather data from visibility meters and humidity sensors installed at the tunnel entrance. Time data can be directly obtained from the system's internal clock. A "threshold-environment" mapping model is pre-stored or algorithmically generated within the control unit. This model then determines a real-time threshold based on weather data and other environmental parameters, allowing for dynamic adjustment of the threshold.

[0094] For example: in heavy rain, fog or snow, visibility is drastically reduced, and the human eye's ability to adapt to changes in light intensity is weakened. In this case, the system should lower the threshold. This means that a smaller difference in light intensity inside and outside the tunnel will trigger the adjustment action, making the brightness transition smoother and safer. For another example: at dusk or dawn, the ambient natural light intensity changes rapidly and is generally dim. The system will also use a stricter (lower) threshold to avoid the risk of excessive darkness outside when the vehicle exits the tunnel.

[0095] According to an embodiment of the second aspect of the present application, the lighting fixture includes a lighting unit, a detection unit and a control component, wherein the lighting unit is used to be installed in a tunnel, the lighting unit is used to adjust the light intensity in the tunnel, the detection unit is used to be installed outside the tunnel, the detection unit is used to detect the light intensity outside the tunnel, and the control component is used to execute the above-mentioned control method.

[0096] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the lighting fixture also includes:

[0097] The lamp body 1 is suitable for installation on the side of a highway. The lamp body 1 is formed with a receiving cavity 11 and a first flow channel 12. The air outlet of the first flow channel 12 is connected to the receiving cavity 11.

[0098] The wind power generation module 5 is arranged in the accommodating cavity 11;

[0099] A first wind collecting cover 6 is mounted on the lamp body 1 , wherein the air outlet of the first wind collecting cover 6 is connected to the air inlet of the first flow channel 12 , and the first wind collecting cover 6 is adapted to guide the external wind to the first flow channel 12 ;

[0100] A main power supply 7 and a backup power supply 8, both of which are electrically connected to the wind power generation module 5;

[0101] The wind power generation module 5, the main power supply 7 and the backup power supply 8 are all electrically connected to the control component.

[0102] According to the lighting fixture of the present application, when vehicles pass by, they drive air rapidly along the highway, which has relatively abundant wind resources. Mounting the lamp body 1 on the side of the highway allows the first wind collector 6 to gather the wind from the highway. This wind is then transported along the first flow channel 12 to the accommodating chamber 11, allowing the wind power generation module 5 to utilize the wind power to generate electricity, thereby improving wind power generation efficiency. The generated wind power from the wind power generation module 5 can then charge the main power supply 7 and / or the backup power supply 8, thus providing the lighting fixture with a power generation function.

[0103] It is understandable that installing the wind power generation module 5 in the accommodating cavity 11 of the lamp body 1 can reduce the impact of the external environment on the wind power generation module 5 and effectively extend the service life of the wind power generation module 5 .

[0104] It can be understood that the wind at the highway is gathered by the first wind gathering cover 6 so that the wind is more concentratedly delivered to the wind power generation module 5, thereby effectively improving the power generation efficiency.

[0105] In one embodiment of the present application, the cross-sectional area of ​​the first flow channel 12 gradually decreases along the direction from the first air collecting cover 6 to the accommodating chamber 11 .

[0106] It can be understood that the wind flow from the highway enters the first flow channel 12 after passing through the first wind collecting cover 6, and then the wind will flow along the first flow channel 12 to the accommodating chamber 11. Since the cross-sectional area of ​​the first flow channel 12 gradually decreases along the flow direction of the wind, the wind speed gradually increases, thereby increasing the wind speed flowing into the accommodating chamber 11, which can improve the efficiency of wind power generation.

[0107] In one embodiment of the present application, the air inlet of the first air collecting cover 6 faces a first direction, and the first direction is the same as the length direction of the lamp body 1 .

[0108] It is understandable that the air inlet of the first wind collecting cover 6 can be arranged opposite to the vehicle's driving direction, so that the wind driven by the vehicle's driving can directly enter the first wind collecting cover 6, thereby facilitating the collection of the wind driven by the vehicle's driving.

[0109] In one embodiment of the present application, the lighting fixture includes a second wind concentrator, which is connected to the lamp body 1. The air inlet of the second wind concentrator is facing in a second direction, the second direction is perpendicular to the length direction of the lamp body 1, and the air outlet of the second wind concentrator is connected to the first flow channel 12.

[0110] It can be understood that when the lighting fixture is located at a location with crosswind, a second wind collecting hood can be set at the lamp body 1 so that the second wind collecting hood can collect wind whose flow direction is perpendicular to the length direction of the lamp body 1, so that the lighting fixture can make full use of the wind resources in the crosswind area to generate electricity.

[0111] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the lamp body 1 is formed with a second flow channel 13 , and the guide section 121 of the first flow channel 12 is connected to the outside through the second flow channel 13 . The cross-sectional area of ​​the guide section 121 is smaller than the cross-sectional area of ​​the air outlet of the first flow channel 12 .

[0112] It can be understood that the cross-sectional area of ​​the air outlet of the first flow channel 12 is larger than the cross-sectional area of ​​the diversion section 121 of the first flow channel 12, then the gas flow rate at the air outlet of the first flow channel 12 will be smaller than the gas flow rate at the diversion section 121, and the second flow channel 13 is connected to the diversion section 121 of the first flow channel 12. Then, under the action of negative pressure, the external airflow will flow into the first flow channel 12 through the second flow channel 13, and then flow out from the air outlet of the first flow channel 12 together, thereby increasing the air outlet at the air outlet of the first flow channel 12, which can effectively improve the wind power generation effect.

[0113] In one embodiment of the present application, the diversion section 121 is located at a position where the cross-sectional area of ​​the first flow channel 12 is the smallest.

[0114] It can be understood that the second flow channel 13 connects the position with the smallest cross-sectional area of ​​the first flow channel 12 and the outside world, ensuring that the gas flow rate at the drainage section 121 is the fastest in the entire first flow channel 12, so that a negative pressure can be formed at the second flow channel 13, ensuring that the external gas can flow into the first flow channel 12 through the second flow channel 13 under the action of negative pressure.
