Description

Technical Field

[0001] This invention relates to the field of road traffic safety technology, specifically a road navigation visual-guided luminous system. Background Technology

[0002] The roads mentioned in this article include highways, tunnels, bridges, etc.

[0003] Early road guidance systems primarily used reflective materials. With technological advancements, current road guidance systems have gradually evolved to primarily use LED lighting.

[0004] In recent years, road guidance lighting systems have mainly included tunnel LED speed control guidance systems represented by patent numbers CN 201921559611, CN 202020765671, and CN 202020206012; speed control guidance systems linked with speed measuring instrument feedback, represented by patent numbers CN215526927U and CN 201910293124.6, which utilize a periodic on-off guiding light pattern and are mainly used in highway tunnels in southern provinces with many tunnels, such as Zhejiang Province; and fog-day guidance and rear-end collision prevention lighting systems represented by patent numbers CN 108877247A and CN 111583686, which are mainly used on highways in northern provinces.

[0005] The LED speed control and guidance system can guide drivers to drive within a certain safe speed range, effectively improving road traffic efficiency. It has been recognized and valued by the industry and has also been rapidly developed and applied. Especially in the application of speed control and guidance in tunnels, active road studs that emit blue light in sequence along the direction of tunnel traffic are installed on the sidewalks on both sides of the tunnel. In the section of Zhejiang Expressway alone, more than 100 long expressway tunnels have been fully equipped with LED timed illumination guidance systems.

[0006] However, this inducement system has significant technical vulnerabilities and limitations:

[0007] 1. In order to achieve high LED light visibility, the speed control guidance system requires the LED to emit light with high brightness (luminous intensity) and in a periodic on-off sequence (similar to a running light pattern moving forward). Due to psychological factors, the driver's visual nerves will passively follow the LED. Although the driving speed is controlled, the probability of speeding is reduced, and the traffic efficiency is improved accordingly, the running light pattern of the guidance system can also cause the driver to have the illusion of floating on the road or a sense of disorientation. In particular, the driver will see the lights chasing behind the car in the rearview mirror, which will cause a loss of sense of speed, and further a lack of sense of distance and orientation. Long-distance following will create a sense of monotony, and this illusion will be more serious when driving in this following style for a particularly long distance. In certain situations, this can induce the driver to make mistakes, thus posing a potential risk of traffic accidents.

[0008] 2. Since there will inevitably be vehicles with different speed requirements on the road, such as heavy trucks that should not travel too fast, or some low-performance or old vehicles that need to travel at low speeds due to power limitations, the speed will inevitably increase under the guidance of this system, leading to loss of vehicle control.

[0009] 3. The design of open-air highways differs significantly from that of highway tunnels. Highway tunnels are essentially like straight lanes, while open-air highways often have inconsistent speed requirements between the inner and outer lanes. For example, on highways, the inner lane is the fast lane and the outer lane is the slow lane. This can cause drivers to experience a feeling of inconsistent lateral movement. Similarly, on curved sections of open-air highways, the inner and outer diameters differ, leading to different speed requirements for the inner and outer lanes, which can cause dizziness. Current technologies fall short in these areas. Furthermore, the ambient light levels on open-air roads fluctuate greatly between day and night. On low-grade highways, nighttime road surface illumination is as low as 3-5 lux, while daytime illumination reaches tens of thousands of lux. Therefore, the visibility of existing technologies is significantly limited, and their widespread adoption on ordinary roads poses significant traffic safety risks.

[0010] Moreover, existing technologies are only suitable for relatively closed road conditions such as tunnels or highways, and the mileage of roads in these applications accounts for a small percentage of the national highway system. Obviously, for relatively open ordinary roads of different grades that account for a larger proportion of the highway mileage, the road and vehicle conditions are relatively complex, which limits the application of these technologies. This is especially true on roads where motor vehicles and non-motor vehicles share the same traffic, where the speeds of motor vehicles and non-motor vehicles are often different, making it impossible to accommodate both simultaneously, further complicating the situation and increasing the risks associated with their application.

[0011] With the widespread adoption of autonomous driving technology, and the coexistence of autonomous and manual driving, the timing intervals required by existing induced illumination systems are significantly too large relative to the video sampling frequency of visual recognition cameras. This hinders the acquisition of road contour video data by the cameras and increases the difficulty of post-processing. Therefore, existing technology is not suitable for the reality of coexisting manual and autonomous driving, exhibiting obvious technical flaws. To expand the application scope of this guidance technology, the above problems must be solved; otherwise, potential safety hazards will continue to grow. Unfortunately, no good solution has yet been found.

[0012] In particular, speed control and guidance systems that combine radar or video acquisition, represented by patent number CN 202310023162.6, and intelligent speed control and guidance systems, represented by patent number CN 116863703A, have made innovative breakthroughs in terms of application scenarios and intelligence. However, there is no description of any existing technologies regarding the shortcomings of line-of-sight guidance and the corresponding solutions to improve recognition. Moreover, technical personnel in this industry mostly conduct technical research and development in circuit design and circuit control, and there is no information on seeking technical breakthroughs from the perspective of luminescence and human vision. There are also no application cases or related reports in the industry. Summary of the Invention

[0013] Addressing the existing technical vulnerabilities, defects, security risks, and application limitations of current technologies, this invention starts from the source of the technology. Based on traffic safety technology and traffic industry regulations, and primarily from the perspectives of optics and optical control theory combined with visual psychology and physiology, this invention uses photometry, colorimetry, and photoelectric control technology theories for theoretical calculations and experimental verification. The technical problem this invention aims to solve is to creatively propose and provide a time-series luminous visual guidance road navigation system that can improve road traffic efficiency, enhance safety, improve visual guidance recognition, broaden applicability, and features a positioning brightness emission sequence.

[0014] This invention, by incorporating a visual reference system of a directional brightness emission sequence and / or a directional illuminance emission sequence, allows the driver's eyes to simultaneously perceive a directional brightness emission sequence and / or a directional illuminance emission sequence moving backward while tracking the temporal emission sequence of a horse moving forward under psychological guidance (providing the driver with a visual reference system for perceiving backward movement). This re-enhances the driver's sense of speed, prevents optical illusions, and allows the driver to regain their sense of orientation by relying on the directional reference system even after an illusion occurs.

[0015] Furthermore, by using the left and right sides of the road surface or combining lane markings to form a two-dimensional reference system, the driver's sense of planar orientation and distance is supplemented. By further combining the vertical surfaces that have a height difference with the road surface to establish a three-dimensional reference system, the driver's sense of three-dimensional orientation in the road space environment is further enhanced, the visual light environment reference system is improved, and vehicles at different speeds can also travel at their respective speeds without losing control of the vehicle speed.

[0016] This invention not only solves many problems such as technical loopholes in the existing technology, but also proposes new solutions to improve the accuracy of guidance identification and visual perception, and proposes a general solution for all-weather application scenarios of different road grades, which has significant social and economic benefits.

[0017] The core technical means by which this invention solves the problem lies in:

[0018] To address the problem of drivers experiencing a sense of floating or disorientation, this invention combines road traffic safety technology and traffic regulations, and from the perspectives of visual physiology and psychology, introduces a positioning brightness emission sequence, which can restore the driver's sense of speed and journey, as well as provide a sense of distance and orientation.

[0019] However, under the premise of the brightness emission sequence for positioning, the recognizability of the brightness emission sequence that moves longitudinally forward in time will inevitably decrease to a certain extent, affecting the navigation guidance effect. If the brightness of the brightness emission sequence for positioning is too low, it will be difficult for the human eye to recognize, and it will not serve as a positioning reference for the driver. On the other hand, in order to improve the visibility (recognition) of the brightness emission sequence that moves longitudinally forward in time, excessively increasing its brightness will pose a negative risk of glare. Moreover, excessively high light intensity will inevitably cause excessive power supply load, which will increase the implementation cost. In addition, line loss will also cause voltage power supply instability, resulting in inconsistent brightness and affecting the light guidance effect.

[0020] To address the aforementioned technical challenges, this invention, based on photometric theory and combined with photoelectric control technology, utilizes circuit control methods such as controlling luminous brightness L or luminous intensity I, luminous period T, duty cycle D, and timing circuits. It also incorporates visual physiology and psychology, considering the driver's photopic, mesopic, and scotopic vision perspectives. Furthermore, it combines theoretical calculations and simulation experiments based on changes in road ambient illuminance and the human visual function. Specifically, it references evaluation methods related to flicker light source fluctuation depth [fluctuation depth = (AB) / (A+B)×100%] and flicker index [flicker index = S1 / (S1+S2)] to determine the proportional relationship between the luminous brightness L or luminous intensity I of the longitudinally shifted luminous emission sequence two (L2) and the positioned luminous emission sequence one (L1). This aims to simultaneously improve sufficient visibility and the driver's visual response and reaction time while controlling the negative effects of excessive glare, and minimizing psychological fatigue.

[0021] Further, based on the theoretical foundation of colorimetry, the emission wavelength λ1 of the positioned brightness emission sequence and the emission wavelength λ2 of the brightness emission sequence that moves forward longitudinally in time are matched to the emission color. Furthermore, different emission colors (corresponding to different wavelength λ distributions) can further improve the recognition and driver's visual reaction ability. This truly solves the technical problem of the relatively low recognition of the combination of relatively strong and relatively weak emission bodies, so that both the brightness emission sequence that moves forward longitudinally in time and the positioned brightness emission sequence can maintain sufficient recognition.

[0022] Furthermore, by adjusting the brightness emission sequence that moves longitudinally forward in a time sequence and the brightness emission sequence that is positioned, different emission areas or emission angles can be used to improve recognition and the driver's visual reaction ability.

[0023] Further configuration of illumination enhancement movement sequences can be used to strengthen the visual reference system, making the human eye's field of vision wider, which can speed up the driver's reaction time, reduce eye strain, and reduce fatigue.

[0024] It can also enhance the projection light with an illuminance greater than 3 times the ambient light intensity. The preferred illuminance enhancement projection light and shadow are longitudinally forward-moving light emission sequences in a time sequence. The electroluminescent bodies, which are grouped in the same way and controlled by the same timing circuit, move synchronously with the same period and duty cycle, expanding the driver's field of vision and improving recognition. This further enhances the driver's sense of speed and spatial orientation, reduces eye strain, and is less likely to cause visual fatigue.

[0025] The illumination enhancement positioning sequence can be further configured to make the driver's spatial orientation clearer.

[0026] Further retroreflective units can be used to assist in positioning sequences, making the driver's spatial orientation clearer.

[0027] Fluorescent materials can be further added to the positioning sequence, and the fluorescent materials can be excited to emit light by outdoor ultraviolet light during the day to improve the recognizability of the positioning sequence on the highway during the day.

[0028] Long-afterglow luminescent materials can be further added to the positioning sequence, and the long-afterglow luminescent materials can be excited to emit light by nighttime floodlights, so as to improve the recognizability of the positioning sequence on the highway at night.

[0029] Furthermore, by adding sensors and achieving intelligent linkage control with them, multi-functional or multi-mode light emission can be realized, thus better adapting to the technological development direction of intelligent control. Alternatively, by linking with the back-end control system or connecting to the cloud control system, the brightness emission sequence (L1) of the positioning system can be more easily matched with the road information collected by machine vision, thereby better meeting the social development needs of intelligent transportation.

[0030] This invention not only systematically solves the problems existing in the prior art, but also further improves road traffic efficiency and enhances traffic safety. It also adds a luminous guidance function, improving road lighting and aesthetics to a certain extent. Furthermore, it is more suitable for further enhancing its alarm, warning, and other linkage or intelligent control capabilities, making it applicable to various road scenarios. It can be used for speed control guidance in tunnels, as well as navigation, guidance, and turning guidance on ordinary roads, offering stronger guidance functions. It can be applied to both high-grade highways and low-grade roads with mixed motor vehicle and non-motor vehicle traffic, broadening its application range, and can even be used for slow-speed guidance in non-motor vehicle lanes. It can provide guidance both at night and during the day, offering greater environmental adaptability and possessing significant economic and social value.

[0031] Technical solution A of the present invention is: a road navigation visual induced light emission system, comprising a road segment and an induced light emission system located on the left and / or right sides of the lane in that road segment, consisting of multiple induced light emission units equipped with electroluminescent elements arranged in a longitudinal spacing S1 along the lane extension direction.

[0032] The electroluminescent body is equipped with a circuit-controlled electroluminescent body that periodically emits light to form a localized brightness emission sequence (L1) arranged at longitudinal intervals S1 along the lane extension direction and emitting light with a certain chromaticity (mainly corresponding to the emission color or hue). The localized brightness emission sequence (L1) consists of individual elements emitting light with periodic brightness changes of period T1, while the entire brightness emission sequence group emits light synchronously and periodically with emission brightness L1 (λ1) or emission intensity I1 (λ1).

[0033] The electroluminescent body is equipped with an electroluminescent body controlled by a timing circuit, which emits light at a set period and duty cycle to form a second brightness emission sequence (L2) that emits light at a certain chromaticity and moves longitudinally forward in a time sequence along the lane extension direction at a longitudinal spacing of S2=n*S1 (3≤n≤20, n is an integer). The second brightness emission sequence (L2) that moves longitudinally forward in a time sequence is a brightness emission sequence that moves forward (relative to the driver) by a distance S1 at time intervals t3 along the road segment from beginning to end (i.e., the group movement speed of the second brightness emission sequence (L2) that moves longitudinally forward in a time sequence is V=S1 / t3) and emits light with a brightness L2 (λ2) or a light intensity I2 (λ2).

[0034] The light spots of the second (L2) brightness emission sequence with a longitudinal spacing of S2 and a time-sequential longitudinal forward movement overlap or partially overlap or run parallel with some light spots in the first (L1) brightness emission sequence with a longitudinal spacing of S1, forming a longitudinal combination emission (outline) line of sight.

[0035] Among them, the luminance L1 (λ1) of the first luminance emission sequence (L1) facing the driver and passengers is less than the luminance L2 (λ2) of the second luminance emission sequence (L2) facing the driver and passengers, which is shifted longitudinally according to the time sequence.

[0036] Alternatively, the luminous intensity I1 (λ1) of the first luminous emission sequence (L1) facing the driver and passengers is less than the luminous intensity I2 (λ2) of the second luminous emission sequence (L2) facing the driver and passengers, which is shifted longitudinally according to the time sequence.

[0037] The first luminance emission sequence (L1) and the second luminance emission sequence (L2) that are shifted forward in time sequence are luminance emission sequences with different emission wavelength distributions and thus have a certain chromaticity difference (preferably RGB contrasting hues), or the first luminance emission sequence (L1) and the second luminance emission sequence (L2) that are shifted forward in time sequence are luminance emission sequences with the same or similar emission chromaticity.

[0038] Technical solution B of the present invention is: a road navigation visual induced light emission system, comprising a road segment and an induced light emission system located on the left and / or right sides of the lane in that road segment, consisting of multiple induced light emission units equipped with electroluminescent elements arranged in a longitudinal spacing S1 along the lane extension direction.

[0039] The electroluminescent body is provided with a circuit-controlled electroluminescent body that emits light constantly to form a positioning brightness emission sequence (L1) arranged at a longitudinal spacing S1 along the extension direction of the lane and emitting light with a certain chromaticity. The positioning brightness emission sequence (L1) is a positioning brightness emission sequence (L1) that emits light with a constant luminous brightness L1 (λ1) or a constant luminous intensity I1 (λ1).

[0040] The electroluminescent body is equipped with an electroluminescent body controlled by a timing circuit to emit light at a set period and duty cycle, forming a second brightness emission sequence (L2) that emits light in a certain chromaticity and moves longitudinally forward in a time sequence along the lane extension direction at a longitudinal spacing of S2=n*S1 (3≤n≤20, n is an integer). The second brightness emission sequence (L2) that moves longitudinally forward in a time sequence is a second brightness emission sequence (L2) that moves forward (relative to the driver) by a distance S1 at a time interval t3 along the road segment from beginning to end (i.e., the group speed of the second brightness emission sequence (L2) that moves longitudinally forward in a time sequence is V=S1 / t3) and emits light with a brightness of L2 (λ2) or a light intensity of I2 (λ2).

[0041] The light spots of the second (L2) brightness emission sequence with a longitudinal spacing of S2 and a time-sequential longitudinal forward movement overlap or partially overlap or run parallel with some light spots in the first (L1) brightness emission sequence with a longitudinal spacing of S1, forming a longitudinal combination emission (outline) line of sight.

[0042] Among them, the luminance L1 (λ1) of the first luminance emission sequence (L1) facing the driver and passengers is less than the luminance L2 (λ2) of the second luminance emission sequence (L2) facing the driver and passengers, which is shifted longitudinally according to the time sequence.

[0043] Alternatively, the luminous intensity I1 (λ1) of the first luminous emission sequence (L1) facing the driver and passengers is less than the luminous intensity I2 (λ2) of the second luminous emission sequence (L2) facing the driver and passengers, which is shifted longitudinally according to the time sequence.

[0044] The first brightness emission sequence (L1) and the second brightness emission sequence (L2) that are shifted forward in time sequence are brightness emission sequences with different emission wavelength distributions and thus have a certain chromaticity difference, or the first brightness emission sequence (L1) and the second brightness emission sequence (L2) that are shifted forward in time sequence are brightness emission sequences with the same or similar emission chromaticity.

[0045] Furthermore, the brightness emission sequence one (L1) positioned in the aforementioned location has a different emission wavelength distribution than the brightness emission sequence two (L2) shifted longitudinally in time sequence, thus exhibiting a certain chromaticity difference.

[0046] The emission spectrum of the brightness emission sequence one (L1) of the positioning corresponds to the spectral hue with a high response of human mesovision or human scotopic vision (corresponding to human visual function).

[0047] Alternatively, the brightness emission sequence one (L1) positioned in the aforementioned location may have a different emission wavelength distribution than the brightness emission sequence two (L2) shifted longitudinally in time sequence, thus exhibiting a certain chromaticity difference.

[0048] The emission spectrum of the brightness emission sequence two (L2) that is shifted forward in time corresponds to the spectral hue with a high response in human mesovision or human photopic vision (corresponding to the human visual function).

[0049] Preferably, the first luminance emission sequence (L1) and the second luminance emission sequence (L2) that is shifted longitudinally in time sequence are luminance emission sequences with contrasting hues.

[0050] Furthermore, when the road ambient illuminance is less than 1500 Lux (mainly corresponding to tunnels or roads at night), an illuminance projection brightening sequence is provided on the left and / or right sides of the lane. This sequence consists of multiple illuminance projection (projection) units with electroluminescent elements, arranged along the lane extension direction and equidistantly aligned with the induced light emission units of the induced light emission system at a longitudinal spacing of S1 (generally referring to equidistant or aligned positions or intervals within the construction error range at the same mileage cross-section along the road extension direction).

[0051] The illuminance projection unit is equipped with electroluminescent bodies that are grouped in the same manner as the sequential longitudinally shifting brightness emission sequence (L2) and controlled by the same timing circuit. These electroluminescent bodies emit light synchronously with the same period and duty cycle and emit light in a similar color. This forms an illuminance enhancement projection light and shadow (the luminous brightness of the illuminated road surface or sidewall) sequentially shifting longitudinally along the lane extension direction at a longitudinal spacing of S2=n*S1 (3≤n≤20, where n is an integer). The illuminance enhancement projection light and shadow sequentially shifting longitudinally (E2) is a group of illuminance enhancement projection light and shadow sequences that move forward a distance of S1 each time along the road segment at a set time interval t3, and enhance the illuminance of the projected light with an increased illuminance e2.

[0052] Specifically, the enhanced illumination e2 is more than 3 times the ambient illumination (road surface ambient illumination, side wall ambient illumination, guardrail ambient illumination), or the brightness of the illuminated enhanced illumination area or section is more than 3 times the brightness of the surrounding unilluminated areas or sections, thereby enhancing the visual reference system of the surrounding illumination environment, resulting in faster visual nerve response and less strain on the human eye; preferably, the projection angle is perpendicular to the road surface extension direction or to the side and forward.

[0053] Furthermore, when the road ambient illuminance is less than 1500 Lux (mainly corresponding to tunnels or roads at night), an illuminance projection brightening sequence is provided on the left and / or right sides of the lane. This sequence consists of multiple illuminance projection (projection) units with electroluminescent bodies, arranged along the lane extension direction and equidistantly aligned with the induced light emission units of the induced light emission system at a longitudinal spacing of S1 (generally referring to equidistant or aligned positions or intervals within the construction error range at the same mileage cross-section along the road extension direction).

[0054] The illuminance projection unit is equipped with an electroluminescent body controlled by the same circuit as the positioned brightness emission sequence (L1). The electroluminescent body emits light synchronously and periodically with the same period and with a similar emission color, forming an illuminance enhancement projection light and shadow positioning emission sequence (E1) arranged at a longitudinal spacing S1 along the lane extension direction. The illuminance enhancement projection light and shadow positioning emission sequence (E1) emits light with periodic brightness changes of periodic period T1 and enhances the brightness of the projected light with an enhanced projection illuminance e1.

[0055] The enhanced illumination e1 is more than three times the ambient illumination (road surface illumination, side wall illumination, guardrail illumination), or the brightness of the illuminated enhanced illumination area or section is more than three times the brightness of the surrounding unilluminated areas or sections, which enhances the visual reference system of the surrounding illumination environment, makes the visual nerves react faster, and makes it easier for the human eye; preferably, the projection angle is perpendicular to the road surface extension direction or to the side and forward.

[0056] Preferably, the illumination enhancement projection light and shadow longitudinally forward-moving luminescence sequence (E2) and the longitudinally forward-moving brightness luminescence sequence (L2) are moving luminescence sequences in which electroluminescent bodies in the same group and controlled by the same timing circuit move synchronously to emit light with the same period and duty cycle.

[0057] Preferably, the illumination enhancement projection light and shadow longitudinally forward-shifting luminous sequence (E2) is a moving luminous sequence whose luminous color is similar to that of the positioned brightness luminous sequence (L1).

[0058] Furthermore, when the emission wavelength λ1 of the first positioning brightness emission sequence (L1) is the same as or similar to the emission wavelength λ2 of the second brightness emission sequence (L2) shifted longitudinally in time (i.e., the same color system or similar color system) (i.e., emission wavelength λ1 is equal to or approximately equal to emission wavelength λ2), or when the hue difference angle between the emission hue of the first positioning brightness emission sequence (L1) and the emission hue of the second brightness emission sequence (L2) shifted longitudinally in time is less than 30°,

[0059] The luminance L1(λ1) of the first luminance sequence (L1) facing the driver and passengers, and the luminance L2(λ2) of the second luminance sequence (L2) moving longitudinally forward according to the time sequence, facing the driver and passengers, are controlled within the range of 1 / 30 ≤ L1: L2 ≤ 1 / 3. Wherein, luminance L1(λ1) and luminance L2(λ2) are both their peak luminance, or luminance L1(λ1) and luminance L2(λ2) are both their average luminance.

[0060] Alternatively, the luminous intensity I1 of the first (L1) brightness emission sequence facing the driver and passengers and the luminous intensity I2 of the second (L2) brightness emission sequence moving longitudinally forward according to time sequence facing the driver and passengers can be controlled within 1 / 30≤I1:I2≤1 / 3, wherein the luminous intensity L1 (λ1) and the luminous intensity L2 (λ2) are both their peak luminous intensity, or the luminous intensity L1 (λ1) and the luminous intensity L2 (λ2) are both their average luminous intensity.

[0061] Alternatively, the ratio of the luminous area of ​​the first (L1) brightness luminous sequence facing the driver and passengers to the luminous area of ​​the second (L2) brightness luminous sequence moving longitudinally forward according to the time sequence facing the driver and passengers can be controlled between 1 / 20 and 1 / 2.

[0062] Alternatively, the ratio of the number of electroluminescent bodies in the first (L1) brightness emission sequence facing the driver / passenger direction to the number of electroluminescent bodies in the second (L2) brightness emission sequence moving longitudinally forward according to time sequence facing the driver / passenger direction is controlled between 1 / 20 and 1 / 3.

[0063] Furthermore, when the emission wavelength λ1 of the first luminance emission sequence (L1) is significantly different from the emission wavelength λ2 of the second luminance emission sequence (L2) which is shifted longitudinally in time (i.e., significantly different color systems), or when the hue difference angle between the emission hue of the first luminance emission sequence (L1) and the emission hue of the second luminance emission sequence (L2) is between 60° and 180°,

[0064] The brightness of the first positioning brightness emission sequence (L1) facing the driver and passengers, L1(λ1), and the brightness of the second positioning brightness emission sequence (L2) facing the driver and passengers, which is shifted longitudinally according to time sequence, L2(λ2), are controlled within the range of 1 / 20 ≤ L1 : L2 ≤ 1 / 2. Specifically, both brightness L1(λ1) and brightness L2(λ2) are either their peak brightness or their average brightness.

[0065] Alternatively, the luminous intensity I1 of the first (L1) brightness emission sequence facing the driver and passengers and the luminous intensity I2 of the second (L2) brightness emission sequence moving longitudinally forward according to time are controlled within 1 / 20≤I1:I2≤1 / 2, wherein the luminous intensity L1 (λ1) and the luminous intensity L2 (λ2) are both their peak luminous intensity, or the luminous intensity L1 (λ1) and the luminous intensity L2 (λ2) are both their average luminous intensity.

[0066] Alternatively, the ratio of the luminous area of ​​the first (L1) brightness luminous sequence facing the driver and passengers to the luminous area of ​​the second (L2) brightness luminous sequence moving longitudinally forward according to the time sequence facing the driver and passengers can be controlled between 1 / 15 and 1 / 1.

[0067] The ratio of the number of electroluminescent bodies in the first brightness emission sequence (L1) facing the driver and passengers to the number of electroluminescent bodies in the second brightness emission sequence (L2) facing the driver and passengers in a time-sequential longitudinal forward motion is controlled between 1 / 15 and 1 / 2.

[0068] Furthermore, the angle φ2 between the main emission direction of the longitudinally shifted brightness emission sequence two (L2) and the lane extension direction is between 0° and 15°, and the angle φ1 between the main emission direction of the positioned brightness emission sequence one (L1) and the lane extension direction is between 0° and 90°.

[0069] Alternatively, the angle φ2 between the main emission direction of the longitudinally forward-shifting brightness emission sequence two (L2) and the lane extension direction is smaller than the angle φ1 between the main emission direction of the positioned brightness emission sequence one (L1) and the lane extension direction.

Detailed Implementation

[0242] The embodiments of the present invention are described in conjunction with the accompanying drawings (only brief descriptions are given in the text, because there are very complete technical standards, setting procedures and application specifications and their demonstration scenarios in the field of road traffic. A large number of traffic practitioners can find applications and various application solutions for different levels of roads and tunnels based on the technology of the present invention and in combination with or by referring to industry standards or national standards. The following only uses the most typical road section as an example for illustration. Other non-typical road sections can be deduced by analogy and will not be elaborated).

[0243] Example 1

[0244] A road navigation visual guidance illumination system includes a straight road segment consisting of a fast lane with a speed limit of 120 km / h on the left and a slow lane with a speed limit of 80 km / h on the right; an illumination sequence consisting of multiple LED guidance lights with LED emitters arranged longitudinally at intervals S1=12m on guardrail posts or corrugated guardrail beams on the left and right sides of the road segment; and a sequence of retroreflective markers consisting of guardrail reflective delineators and road surface retroreflective road studs arranged longitudinally at intervals S1=12m, equidistant from the LED guidance lights on the same vertical plane as the lane. Figure 12 As shown,

[0245] The left-side LED guide light of the left-side fast lane is equipped with a circuit-controlled yellow LED emitter.

[0246] A positional brightness emission sequence (L1) is formed by periodic emission along the lane extension direction at a longitudinal spacing of S1=12m. Each individual element of the positional brightness emission sequence (L1) emits periodic flashing light with a period of T1=0.36s and a duty cycle of D1=25%~50%, while the overall brightness of the emission sequence is L1(λ1)=10cd / m. 2 ~100cd / m 2 The brightness emission sequence of periodically synchronized emission.

[0247] The right-side LED guide light in the right-side slow lane is equipped with a circuit-controlled yellow LED emitter.

[0248] A positional brightness emission sequence (L1) is formed by periodic emission along the lane extension direction at a longitudinal spacing of S1=12m. Each individual element of the positional brightness emission sequence (L1) emits periodic flashing light with a period of T1=0.54s and a duty cycle of D1=25%~50%, while the overall brightness of the emission sequence is L1(λ1)=10cd / m. 2 ~100cd / m 2 The brightness emission sequence of periodically synchronized emission.

[0249] The light spots formed by the first brightness emission sequence (L1) of the left fast lane and the first brightness emission sequence (L1) of the right slow lane can be used to identify the lane outline by means of emission frequency (a short emission period or high emission frequency corresponds to a high speed limit, and a long emission period or low emission frequency corresponds to a low speed limit) and emission color (such as yellow LED and white LED respectively).

[0250] The left-side LED guide light in the left-side fast lane is also equipped with green or blue LED emitters grouped in sets of n=4 along the lane extension direction, controlled by a timing circuit. These emitters periodically to form a brightness emission sequence (L2) arranged longitudinally at a spacing of S2=48m along the lane extension direction, moving forward in a time sequence. Each green or blue LED emitter periodically flashes with an individual period T2=1.44s and a duty cycle D2=5%. Adjacent green or blue LED emitters emit sequentially at a time interval t3=0.36s. Thus, within one period T2, each green or blue LED emitter in the same group is sequentially energized along the lane extension direction (vehicle travel direction) with a brightness of L2(λ2)=50cd / m. 2 ~800cd / m 2 The LEDs emit light sequentially, with the corresponding green or blue LEDs in each group emitting light synchronously, forming a pattern along the lane from beginning to end at a speed of V = 12m / 0.36s = 120km / h and an luminance of L2(λ2) = 50cd / m². 2 ~800cd / m 2 Or the luminous intensity I2 (λ2) of the luminous emission is a luminous emission sequence that is shifted longitudinally in time.

[0251] The right-side LED guide light in the right-side fast lane is also equipped with green or blue LED emitters grouped in sets of n=4 along the lane extension direction, controlled by a timing circuit. These emitters periodically to form a brightness emission sequence (L2) arranged longitudinally at a spacing of S2=48m along the lane extension direction. Each green or blue LED emitter periodically flashes with an individual period of T2=2.16s and a duty cycle of D2=5%. Adjacent green or blue LED emitters emit light sequentially at a time interval of t3=0.54s. Thus, within one period T2, each green or blue LED emitter in the same group is sequentially energized along the lane extension direction (vehicle travel direction) with a brightness of L2(λ2)=50cd / m. 2 ~800cd / m 2 The LEDs emit light sequentially, with the corresponding green or blue LEDs in each group emitting light synchronously, forming a pattern along the lane from beginning to end at a speed of V = 12m / 0.54s = 80km / h and an luminance of L2(λ2) = 50cd / m². 2 ~800cd / m 2 Or, the luminous intensity I2 (λ2) is a luminous emission sequence that is longitudinally shifted forward in time.

[0252] Each guardrail post is also equipped with a fluorescent yellow reflective outline marker, and below each guardrail post is a yellow road surface retroreflective road stud that is longitudinally aligned with the corresponding guardrail post (located on the same mileage elevation of the lane). Furthermore, on the median dividing line between the fast lane and the slow lane of this road section, there is also a yellow road surface retroreflective road stud that is longitudinally aligned with the corresponding guardrail post (located on the same mileage elevation of the lane), forming a retroreflective unit auxiliary positioning sequence (R).

[0253] The LED floodlights, LED guide lights, or LED guide signs can be integrated into one unit or arranged separately. Individual LED floodlights, LED guide lights, or LED guide signs can each have their own independent solar power supply system (such as solar lights, solar signs, solar delineators, and solar road studs) and adjust the photometric, colorimetric, and photoelectric control parameters such as period and duty cycle of the visual guidance system via wireless control signals; alternatively, multiple LED floodlights, multiple LED guide lights, or multiple LED guide signs can be clustered together for power supply, and their control can be either wired or wireless to adjust the photometric, colorimetric, and photoelectric control parameters such as period and duty cycle of the visual guidance system.

[0254] Furthermore, its light emission mode or parameters can be adjusted via wired or wireless control signals. For example, in foggy weather, the yellow LED emitter of its positioned brightness emission sequence can be adjusted via wireless control signals to emit light at a higher brightness, thereby providing fog guidance. The time interval t3 of each movement of the longitudinally moving brightness emission sequence can be increased as needed, reducing its forward speed V=S1 / t3, reminding drivers to drive slowly in foggy weather. Or, in the event of a biohazard incident ahead, the longitudinally moving brightness emission sequence or the positioned brightness emission sequence can be controlled to move backward to warn drivers when reversing. Alternatively, road traffic information can be collected via cloud cameras. If the road is clear, the time interval t3 of each movement of the longitudinally moving brightness emission sequence can be appropriately reduced via cloud control, increasing its forward speed V=S1 / t3 to improve road traffic efficiency. If the road is slow, the time interval t3 of each movement of the longitudinally moving brightness emission sequence can be appropriately increased via cloud control, reducing its forward speed V=S1 / t3 to alleviate intersection congestion.

[0255] The road navigation visual guidance illumination system of this invention can simultaneously improve sufficient recognition and driver visual response and reaction time while controlling the negative impact of excessive glare, and is less likely to cause psychological fatigue. It can further improve road traffic efficiency and enhance traffic safety. The photometric parameters, colorimetric parameters, photoelectric control parameters such as period and duty cycle, and sequence spacing of the visual guidance system can be adjusted according to actual road conditions, so that it can be applied to both high-grade highways and low-grade highways with mixed motor vehicle and non-motor vehicle traffic. Its application range is wider, and it can even be used for slow-speed guidance in non-motor vehicle lanes. It has significant economic and social value.

[0256] Example 2

[0257] A road navigation visual guidance illumination system includes a two-lane road section and two guide rail posts or corrugated guardrail beams on the left and right sides of that road section. The system comprises an illumination sequence consisting of multiple LED guidance lights or LED guidance signs arranged longitudinally at intervals S1=8m along the lane extension direction; an illumination projection enhancement sequence consisting of LED floodlights arranged longitudinally at intervals S1=8m along the lane extension direction; and a retroreflective marker sequence consisting of guardrail reflective delineators and road surface retroreflective road studs arranged longitudinally at intervals S1=8m, equidistant from the aforementioned LED guidance lights or LED guidance signs (located on the same mileage elevation of the lane). Figure 13 As shown,

[0258] The left and right LED guide lights or LED guide signs are each equipped with a circuit-controlled yellow LED emitter that periodically emits light to form a positioning brightness emission sequence (L1) arranged along the lane extension direction at a longitudinal spacing of S1=8m. The positioning brightness emission sequence (L1) consists of individual LEDs that periodically flash with a period of T1=0.36s and a duty cycle of D1=30%~75%, while the brightness of the entire emission sequence is L1(λ1)=15cd / m. 2 ~80cd / m 2 The brightness emission sequence of periodically synchronized emission.

[0259] The lane outline is formed by the periodic synchronous emission of light spots from the brightness emission sequence (L1) on the left and right sides of the lane.

[0260] Alternatively, the LED guide lights or LED guide signs on the left and right sides may be equipped with circuit-controlled white or yellow LED emitters with a constant luminous intensity L1(λ1) = 10 cd / m². 2 ~60cd / m 2 The light emission forms a brightness emission sequence (L1) arranged along the lane extension direction with a longitudinal spacing of S1=8m.

[0261] The LED guidance lights or LED guidance signs on the left and right sides of the lane are also equipped with green or blue LED emitters grouped in groups of n=4 along the lane extension direction, controlled by a timing circuit. These emitters periodically form a brightness emission sequence (L2) arranged longitudinally at a spacing of S2=32m along the lane extension direction, moving forward in a time sequence. Each green or blue LED emitter emits periodic strobe light with an individual period of T2=1.44s and a duty cycle of D2=5%. Adjacent green or blue LED emitters emit light sequentially at a time interval of t3=0.36s. Thus, within one period T2, each green or blue LED emitter in the same group is sequentially energized along the lane extension direction (vehicle travel direction) with a brightness of L2(λ2)=65cd / m. 2 ~750cd / m 2 The LEDs emit light sequentially, with the corresponding green or blue LEDs in each group emitting light synchronously, forming a pattern along the lane from beginning to end at a speed of V=8m / 0.36s=80km / h and an luminance of L2(λ2)=65cd / m². 2 ~750cd / m 2 Or, the luminous intensity I2 (λ2) is a luminous emission sequence that is longitudinally shifted forward in time.

[0262] During nighttime, the LED floodlights on the left and right sides of the lane are equipped with white LED emitters controlled by a timing circuit, arranged in groups of n=4 along the lane's extension direction. These emitters periodically, forming a brightening projection light and shadow sequence (E2) arranged longitudinally at 32m intervals along the lane's extension direction. The white LED emitters periodically flicker with an individual period T2=1.44s and a duty cycle D2=5%, and the longitudinally adjacent white LED emitters flicker at time intervals. The light is emitted sequentially at t3=0.36s, so the illumination enhancement projection light and shadow longitudinally forward-moving light emission sequence (E2) and the brightness light emission sequence two (L2) are emitted synchronously in parallel with the same period and duty cycle. Moreover, the illumination enhancement projection light and shadow longitudinally forward-moving light emission sequence (E2) extends obliquely downward along the direction perpendicular to the road surface with an illumination enhancement projection illuminance between 10Lux and 5000Lux, which enhances the visual reference system of the surrounding illumination environment, makes the visual nerves react faster, and makes it less strenuous for the human eye.

[0264] The LED floodlights, LED guide lights, or LED guide signs can be integrated into one unit or arranged separately. Individual LED floodlights, LED guide lights, or LED guide signs can each have their own independent solar power supply system (such as solar lights, solar signs, solar delineators, and solar road studs) and adjust the photometric, colorimetric, and photoelectric control parameters such as period and duty cycle of the visual guidance system via wireless control signals; alternatively, multiple LED floodlights, multiple LED guide lights, or multiple LED guide signs can be clustered together for power supply, and their control can be either wired or wireless to adjust the photometric, colorimetric, and photoelectric control parameters such as period and duty cycle of the visual guidance system.

[0265] The road navigation visual guidance illumination system of this invention can simultaneously improve sufficient recognition and driver visual response and reaction time while controlling the negative impact of excessive glare, and is less likely to cause psychological fatigue, thereby further improving road traffic efficiency and enhancing traffic safety. The system's photometric parameters, colorimetric parameters, period, duty cycle, and sequence spacing can be adjusted according to actual road conditions, making it applicable to both high-grade highways and low-grade highways with mixed motor vehicle and non-motor vehicle traffic. Its application range is wider, and it can even be used for slow-speed guidance in non-motor vehicle lanes; thus, it has significant economic and social value.

It also includes a sequence (R) of retroreflective road studs arranged longitudinally at intervals S1=10m, with the road surface retroreflective studs positioned longitudinally equidistant from the aforementioned LED road signs. According to national road lighting standards, tunnel illumination conditions are divided into entrance, transition, middle, and exit sections, with the tunnel ambient illumination generally between 30Lux and 350Lux. Figure 15 As shown.

[0277] The LED streetlights, active LED road studs, or active LED delineators along the left and right sidewalks are equipped with circuit-controlled yellow LED emitters that periodically emit light into the lane, forming a fixed brightness emission sequence (L1) arranged along the lane extension direction at a longitudinal spacing of S1=10m. Each individual element in the fixed brightness emission sequence (L1) emits periodic strobe light with a period of T1=0.6s and a duty cycle of D1=25%~75%, while the overall brightness of the sequence is L1(λ1)=25cd / m². 2 ~100cd / m 2 A localized brightness emission sequence of periodic synchronous emission.

[0278] The LED road signs, active LED road studs, or active LED contour markers along the left and right sidewalks, facing the driver / passenger direction, are further equipped with green or blue LED emitters grouped in sets of n=4 along the lane extension direction, controlled by a timing circuit.

Each green or blue LED emitter periodically flashes with an individual period T2=2.4s and a duty cycle D2=5%, and adjacent green or blue LED emitters emit sequentially at a time interval t3=0.6s. Thus, within one period T2, each green or blue LED emitter in the same group is sequentially energized along the lane extension direction (vehicle travel direction) with a luminous intensity L2(λ2)=80cd / m². 2 ~1000cd / m 2 The LEDs emit light sequentially, with the corresponding green or blue LEDs in each group emitting light synchronously, forming a pattern along the lane from beginning to end at a speed of V=10m / 0.6s=60km / h and an luminance of L2(λ2)==80cd / m². 2 ~1000cd / m 2 Or the luminous intensity I2 (λ2) is the luminous intensity sequence that is shifted longitudinally in time.

[0280] The photometric parameters, colorimetric parameters, photoelectric control parameters such as period and duty cycle, and sequence spacing of the visually induced emission system can be adjusted according to different sections of the tunnel, including the entrance section, transition section, middle section, and exit section, to increase the sense of travel and reduce fatigue and monotony in long tunnels. It can also be controlled by intelligent control or a big data cloud platform to achieve real-time or intelligent regulation.

[0281] The road navigation visual-guided illumination system of the present invention can simultaneously improve sufficient recognition and driver visual response and reaction time while controlling the negative effects of excessive glare, and is less likely to cause psychological fatigue. It can further improve road traffic efficiency and enhance traffic safety; it has significant economic and social value.

[0283] A tunnel road navigation visual-guided illumination system includes a highway tunnel and an induced illumination sequence consisting of LED road signs or LED road studs or active LED delineators arranged longitudinally at intervals S1=10m along the tunnel's extension direction, positioned along both sides of the sidewalks or the road surface; and an illuminance projection and brightening sequence consisting of side-projection lights with focusing optical structures arranged longitudinally at intervals of 10m along the tunnel's extension direction, positioned longitudinally equidistant from the aforementioned LED road signs on both sides of the tunnel sidewalls. According to national road lighting standards, tunnel illumination conditions are divided into entrance, transition, middle, and exit sections, with the tunnel environment illumination generally between 30Lux and 350Lux. Figure 16 As shown.

[0284] The LED streetlights, active LED road studs, or active LED delineators along the left and right sidewalks are equipped with circuit-controlled yellow LED emitters that periodically emit light into the lane, forming a fixed brightness emission sequence (L1) arranged along the lane extension direction at a longitudinal spacing of S1=10m. Each individual element in the fixed brightness emission sequence (L1) emits periodic strobe light with a period of T1=0.6s and a duty cycle of D1=30%~70%, while the overall brightness of the sequence is L1(λ1)=25cd / m². 2 ~100cd / m 2 A localized brightness emission sequence of periodic synchronous emission.

[0285] Alternatively, the LED streetlights, active LED road studs, or active LED delineators along the left and right sides of the sidewalks, near the driveway, are equipped with circuit-controlled white or yellow LED emitters with a constant luminous intensity L1(λ1) = 20 cd / m². 2 ~80cd / m 2 The light emission forms a localized brightness emission sequence (L1) arranged at a longitudinal spacing of S1=10m along the direction of lane extension.

[0286] The LED road signs, active LED road studs, or active LED contour markers along the left and right sidewalks, facing the driver / passenger direction, are further equipped with green or blue LED emitters grouped in sets of n=4 along the lane extension direction, controlled by a timing circuit. These emitters periodically form a brightness luminescence sequence (L2) arranged longitudinally at a spacing of S2=40m along the lane extension direction, moving forward in a time sequence. Each green or blue LED emitter periodically flashes with an individual period T2=2.4s and a duty cycle D2=5%, and adjacent green or blue LED emitters emit sequentially at a time interval t3=0.6s. Thus, within one period T2, each green or blue LED emitter in the same group is sequentially energized along the lane extension direction (vehicle travel direction) with a luminous intensity L2(λ2)=80cd / m². 2 ~1000cd / m 2 The LEDs emit light sequentially, with the corresponding green or blue LEDs in each group emitting light synchronously, forming a pattern along the lane from beginning to end at a speed of V=10m / 0.6s=60km / h and an luminance of L2(λ2)=80cd / m². 2 ~1000cd / m 2 Or the luminous intensity I2 (λ2) is the luminous intensity sequence that is shifted longitudinally in time.

[0287] The lateral floodlights on both sides of the tunnel [preferably ring-type LED floodlights (projection lights, spotlights) with focusing lens rings or block-type LED floodlights (projection lights, spotlights) with focusing optical structures] are white light floodlights or RGB color-adjustable floodlights. They are equipped with white light LED emitters or RGB color-adjustable LED emitters controlled by a timing circuit, arranged in groups of n=4 along the lane extension direction. These emitters periodically emit light to form a luminous enhancement projection light and shadow sequence (E2) arranged longitudinally at 40m intervals along the lane extension direction. The white light LED emitters or RGB color-adjustable LED emitters periodically flicker with an individual period T2=2.4s and a duty cycle D2=5%, and longitudinally adjacent white light LED emitters or RGB color-adjustable LED emitters emit light sequentially at time intervals t3=0.6s, thereby enhancing the luminous enhancement projection light. The longitudinally shifting light and shadow emission sequence (E2) and the longitudinally shifting brightness emission sequence (L2) emit light synchronously in parallel with the same period and duty cycle. The illuminance-enhancing projection light and shadow emission sequence (E2) extends along the direction perpendicular to the road surface, with an illuminance of 500 Lux to 30000 Lux projected laterally. An arc-shaped, ring-shaped, or segmented projection area is preferred, forming a projection area that coincides with the longitudinally shifting brightness emission sequence (L2). The dynamic illumination enhancement projection rings (including road surface illumination enhancement rings and tunnel sidewall illumination enhancement rings or tunnel roof illumination enhancement rings) move forward synchronously, similar to moving tunnel illumination rings, enhancing the spatial experience. [Furthermore, tunnel reflection arcs (similar to tunnel reflective rings) can be fixed on the tunnel sidewalls in the illumination enhancement projection area to further increase the illumination of the illumination enhancement projection rings], enhancing the visual reference system of the surrounding illumination environment, resulting in faster visual nerve response and less strain on the human eye. Ideally, the illumination enhancement projection light and shadow longitudinally forward-moving emission sequence (E2) and the longitudinally forward-moving brightness emission sequence (L2) should be emission sequences of the same color family to improve visibility; the emission mode or emission parameters can also be adjusted according to the actual road conditions.

[0288] Furthermore, its light emission mode or parameters can be adjusted via wired or wireless control signals. For example, when a traffic accident occurs ahead in the tunnel, the sequentially moving brightness emission sequence can be turned off, and the positioned brightness emission sequence can be controlled to emit light at a higher brightness to warn the driver to stop. Alternatively, tunnel traffic information can be collected via cloud cameras. If tunnel traffic is smooth, the time interval t3 of each movement of the sequentially moving brightness emission sequence can be appropriately reduced via cloud control, increasing its forward speed V=S1 / t3 to improve tunnel traffic efficiency. If tunnel traffic is slow, the time interval t3 of each movement of the sequentially moving brightness emission sequence can be appropriately increased via cloud control, decreasing its forward speed V=S1 / t3 to alleviate congestion in the tunnel.

[0289] The photometric parameters, colorimetric parameters, photoelectric control parameters such as period and duty cycle, and sequence spacing of the visually induced light emission system can be adjusted according to different sections of the tunnel, including the entrance section, transition section, middle section, and exit section, to enhance the sense of travel. In particular, the illumination enhancement sequence, combined with the brightness emission sequence, creates a stronger sense of spatial three-dimensionality and on-site experience, reducing fatigue and monotony in long tunnels. It can also be controlled by intelligent control or a big data cloud platform to achieve real-time or intelligent regulation.

[0290] The road navigation visual-guided illumination system of the present invention can simultaneously improve sufficient recognition and driver visual response and reaction time while controlling the negative effects of excessive glare, and is less likely to cause psychological fatigue. It can further improve road traffic efficiency and enhance traffic safety; it has significant economic and social value.

All modifications, variations, combinations, additions, equivalent substitutions, etc., made within the spirit and principles of the present invention, or the application of the present technology to related and similar technical fields, should be included within the protection scope of the present invention.
