An embodiment of the present application provides a traffic sign indicating device, which is used for indicating a target traffic sign associated with a traffic signal indicator light, and the traffic sign indicating device includes a projection light source, wherein the projection light source and the indication signal switching timing sequence of the traffic signal indicator light are kept synchronous. The projection light source is used for projecting light rays to a target traffic sign associated with the traffic signal indicator lamp under the condition that the traffic signal indicator lamp is turned on; and the light spot formed by the light projected onto the target traffic sign by the projection light source is associated with the indicating signal of the traffic signal indicating lamp.
Specifically, the projection light source may be any light source with controllable light color, such as an incandescent lamp, a fluorescent lamp, a laser lamp, an LED lamp, and the like, and further, the projection light source may also be a projection lamp, and the shape of a light spot formed by the projection lamp projecting onto the target traffic sign may be set according to the shape of a pattern piece in the projection lamp. The traffic signal indicator lamp generally refers to a traffic intersection traffic light, and in order to achieve synchronization of the indication signal switching time sequences of the projection light source and the traffic signal indicator lamp, the projection light source can be connected with a signal source of the traffic signal indicator lamp, and the signal switching time sequence of a control source of the projection light source can be consistent with the signal switching time sequence of the control source of the traffic signal indicator lamp. The traffic sign may be a zebra crossing, a zebra crossing notice sign, a traffic direction line, etc. associated with a traffic signal light. The target traffic sign is related to the traffic signal indicator light, where the related means that the indication effect of the target traffic sign is controlled by the traffic signal indicator light, for example, the target traffic sign takes the zebra crossing of an intersection as an example, at the intersection, the zebra crossing in the traffic light action area is related to the traffic light, when the color of the traffic light is red, the pedestrian is prohibited from passing through the zebra crossing, and when the color of the traffic light is green, the pedestrian can pass through the zebra crossing. The light spots formed by the light projected by the projection light source onto the target traffic sign are associated with the indication signals of the traffic signal indicator lamp, so that the color of the light spots formed by the light projected by the projection light source onto the target traffic sign and the color of the traffic signal indicator lamp can be kept synchronous, and the same indication effect is realized. For example, the target traffic sign takes a zebra crossing at an intersection as an example, when the color of the traffic signal indicator light is red, the light spot formed by the light projected by the projection light source onto the target traffic sign can be a character or a pattern which can clearly indicate that pedestrians are prohibited from passing through the zebra crossing, such as "prohibited" or "stopped", and the like; when the color of the traffic signal indicator light is green, the light spots formed by the light projected onto the target traffic sign by the projection light source can be 'traffic' or the like, so that words or patterns allowing pedestrians to pass through the zebra crossing can be clearly represented.
Referring to fig. 1, a schematic view of the installation of a traffic sign indicating device is provided. As shown in fig. 1, the target traffic sign 16 is a zebra crossing, and the projection light source 12 is installed above the traffic sign 16, and may be right above, left above, or right above, as long as it is ensured that the light of the projection light source 12 can be projected onto the target traffic sign 16. However, in order to ensure that the light projected by the projection light source 12 does not affect the surrounding environment, it is preferable to install the projection light source 12 directly above the traffic sign 16. As for the fixing manner of the projection light source 12, a support rod may be erected at a place where the surrounding environment is not affected, and the projection light source 12 may be fixed above the target traffic sign 16, or the projection light source 12 may be installed at a position where the support rod for fixing the traffic signal indicating lamp is not affected and the normal operation of the traffic signal indicating lamp is not affected, or the projection light source 12 may be installed at a position where the building beside the traffic signal indicating lamp is not affected and the surrounding environment is not affected, for example, a rain shed beside a non-motor lane at an intersection, or the like. The specific fixing mode can be any one of gluing, magnetic attraction, air attraction or buckle connection. The distance and angle between the projection light source 12 and the target traffic sign 16 can be adjusted according to the requirement, for example, if the light intensity of the projection light source 12 projected to the target traffic sign 16 is desired to be greater, the distance between the projection light source 12 and the target traffic sign 16 can be closer. If the light projected by the projection light source 12 to the target traffic sign 16 is more uniform, the light emergent surface of the projection light source 12 may be parallel to the plane of the target traffic sign 16. In addition, in the case where the range of the projection light source 12 is insufficient, the number of the projection light sources 12 may be plural. To achieve the synchronization of the indication signal switching timing of the projection light source 12 and the traffic signal indicator, as an alternative embodiment, the projection light source 12 may be connected to the control source of the traffic signal indicator, or the signal switching timing of the control source 18 of the projection light source 12 may be synchronized with the signal switching timing of the control source of the traffic signal indicator.
In the prior art, the traffic sign is coated with a reflective material, light rays are reflected by an optical system comprising a convex lens and a concave mirror, and the light rays irradiated by a vehicle lamp are projected to eyes of pedestrians or drivers, so that the traffic sign is indicated. However, the reflective material is easy to fall off and damaged, the reflective capability is not strong in rainy days, and in addition, under the condition that no car lamp is arranged nearby, the indication effect on pedestrians cannot be achieved, so that the problem that the traffic sign recognition effect is poor is caused.
In the present embodiment, the timing of switching the indication signal of the traffic signal indicator lamp is synchronized with the projection light source 12; a projection light source 12 for projecting light to a target traffic sign 16 associated with a traffic signal indicator lamp when the traffic signal indicator lamp is on; wherein, the light spot formed by the light projected by the projection light source 12 onto the target traffic sign 16 is related to the indication signal of the traffic signal indicator light.
For example, at an intersection with a traffic light, the traffic light is associated with a zebra crossing for indicating that a pedestrian is crossing the road through the zebra crossing. Because the traffic light is associated with the zebra crossing, the light spots formed by the light projected onto the zebra crossing by the projection light source 12 are associated with the traffic light indicating signals, and even if the pedestrians cannot notice the color of the traffic light, the pedestrians can judge whether the zebra crossing passes at the moment by seeing the light spots on the zebra crossing, and in addition, the drivers can be effectively reminded of the passing condition of the current zebra crossing according to the light spots formed by the light projected onto the zebra crossing by the projection light source 12, so that the drivers can adjust the driving state in time.
The light of the projection light source 12 is projected onto the target traffic sign 16, and the light spots formed by the light projected onto the target traffic sign 16 by the projection light source 12 are associated with the indication signals of the traffic signal indicator lamps to indicate the target traffic sign 16, so that the influence of the environment and the weather is avoided, pedestrians and drivers can be effectively reminded, and the identification effect of the traffic sign is improved.
In one embodiment, the projection light source 12 is a projection lamp, the shape of the light projected by the projection light source 12 is consistent with the shape of the target traffic sign 16, and the color of the light projected by the projection light source 12 onto the target traffic sign 16 is synchronized with the color of the traffic signal indicator lamp.
Specifically, since the shape of the pattern piece in the projection lamp projected onto the target traffic sign 16 can be set according to the shape of the pattern piece in the projection lamp, in the present embodiment, the shape of the pattern piece in the projection lamp is set so that the shape of the light projected by the projection light source 12 is consistent with the shape of the target traffic sign 16. For example, the zebra stripes are comb-shaped, have a length of 3 m to 5 m, and each zebra stripe has a width of 45 cm or 60 cm, and the shape of the light projected by the projection lamp is made to coincide with the shape of the target traffic sign 16 by setting the shape of the pattern piece in the projection lamp. Under the action of the control source 18 of the projection light source 12, the color of the light projected by the projection light source 12 onto the target traffic sign 16 is kept synchronous with the color of the traffic signal indicating lamp, so that the indicating effect on the target traffic sign 16 can be enhanced, and the identification effect of the traffic sign is further effectively improved.
In one embodiment, the projection light source 12 is connected to a signal source of a traffic signal indicator light.
By connecting the projection light source 12 with the signal source of the traffic signal indicating lamp, the switching time sequence of the indication signals of the projection light source 12 and the traffic signal indicating lamp can be accurately kept synchronous, the setting operation of the control source 18 of the projection light source 12 is reduced, and the cost of the traffic sign indicating device can be further saved.
Further, as shown in fig. 2, in one embodiment, in order to enhance the indication effect on the target traffic sign 16, the traffic sign indication device further includes a light leakage plate 14, the light leakage plate 14 is disposed on one side of the light emitting surface of the projection light source 12, the shape of the light leakage plate 14 matches the shape of the target traffic sign 16, and the projection light of the projection light source 12 is projected onto the target traffic sign 16 through the light leakage plate 14 to form a light spot, which is in accordance with the shape of the target traffic sign 16. The color of the light projected by the projection light source 12 onto the target traffic sign 16 is synchronized with the color of the traffic signal indicator light.
Specifically, the light leakage plate 14 may be made of any opaque plate, such as a steel plate, a wood plate, or the like, the light leakage plate 14 is disposed on one side of the light emitting surface of the projection light source 12, and the light leakage plate 14 is processed to a shape matching the shape of the target traffic sign 16 in order to make the shape of the light spot formed by the projection light of the projection light source 12 projected onto the target traffic sign 16 through the light leakage plate 14 conform to the shape of the target traffic sign 16. For example, the zebra stripes are comb-shaped, the length of each zebra stripe is 3 to 5 meters, the width of each zebra stripe is 45 or 60 centimeters, the shape of the specific light leakage part of the corresponding light leakage plate is matched with the shape of the zebra stripe, and the shape of the light spot of the light of the projection light source 12 after penetrating through the light leakage plate 14 is consistent with the shape of the zebra stripe by virtue of the pinhole imaging principle. Under the action of the control source 18 of the projection light source 12, the color of the light projected by the projection light source 12 onto the target traffic sign 16 is kept synchronous with the color of the traffic signal indicating lamp, so that the indicating effect on the target traffic sign 16 can be enhanced, and the identification effect of the traffic sign is further effectively improved.
Referring to fig. 2, a schematic view of the installation of a traffic sign indicating device is provided. As shown in fig. 2, the target traffic sign 16 is a zebra crossing, and the projection light source 12 is installed above the traffic sign 16, and may be right above, left above, or right above, as long as it is ensured that the light of the projection light source 12 can be projected onto the target traffic sign 16. However, in order to ensure that the light projected by the projection light source 12 does not affect the surrounding environment, it is preferable to install the projection light source 12 directly above the traffic sign 16. As for the fixing manner of the projection light source 12, a support rod may be erected at a place where the surrounding environment is not affected, and the projection light source 12 may be fixed above the target traffic sign 16, or the projection light source 12 may be installed at a position where the support rod for fixing the traffic signal indicating lamp is not affected and the normal operation of the traffic signal indicating lamp is not affected, or the projection light source 12 may be installed at a position where the building beside the traffic signal indicating lamp is not affected and the surrounding environment is not affected, for example, a rain shed beside a non-motor lane at an intersection, or the like. The specific fixing mode can be any one of gluing, magnetic attraction, air suction, screw connection or buckle connection. The distance and angle between the projection light source 12 and the target traffic sign 16 can be adjusted according to the requirement, for example, if the light intensity of the projection light source 12 projected to the target traffic sign 16 is desired to be greater, the distance between the projection light source 12 and the target traffic sign 16 can be closer. If the light projected by the projection light source 12 to the target traffic sign 16 is more uniform, the light emergent surface of the projection light source 12 may be parallel to the plane of the target traffic sign 16. In addition, in the case where the range of the projection light source 12 is insufficient, the number of the projection light sources 12 may be plural. The signal switching timing of the control source 18 of the projection light source 12 is synchronized with the signal switching timing of the control source of the traffic signal indicating lamp, and the control source 18 of the projection light source 12 can control the projection light source 12 and the traffic signal indicating lamp to change colors in synchronization. The light leakage plate 14 is disposed at one side of the light emitting surface of the projection light source 12, and the light leakage plate 14 can be fixed on the support rod between the light emitting surface of the projection light source 12 and the plane of the target traffic sign 16. As one embodiment, as shown in fig. 3, the projection light source 12 is mounted on a support rod, the projection light source 12 includes a lamp housing, and the light leakage plate 14 may be mounted in the lamp housing of the projection light source 12. The distance and the angle between the light leakage plate 14 and the target traffic sign 16 can be adjusted according to requirements, and when the distance and the angle between the light leakage plate 14 and the target traffic sign 16 are adjusted, the shape of the light leakage plate 14 is adjusted accordingly, so that the shape of a light spot formed by the projection light of the projection light source 12 projecting on the target traffic sign 16 through the light leakage plate 14 can be ensured to be consistent with the shape of the target traffic sign 16.
By utilizing the light leakage plate 14, the shape of a light spot formed by the projection light of the projection light source 12 projected on the target traffic sign 16 through the light leakage plate 14 is consistent with the shape of the target traffic sign 16, and under the action of the control source 18 of the projection light source 12, the color of the light projected on the target traffic sign 16 by the projection light source 12 is kept synchronous with the color of the traffic signal indicator light, so that the recognition effect of the traffic sign is further effectively improved.
With continued reference to FIG. 2, in one embodiment, the position of the projection light source 12 and the light leakage plate 14 may be adjusted in order to make the use of the traffic sign indicating device more flexible.
Specifically, the distance between the projection light source 12 and the light leakage plate 14 and the target traffic sign 16 is adjustable, and the installation angle of the projection light source 12 and the light leakage plate 14 is adjustable. However, in the case where the distance between the projection light source 12 and the light leakage plate 14 is different from the target traffic sign 16 or in the case where the light leakage plate 14 is installed at a different angle, the shape of the light leakage plate 14 is adjusted accordingly, so that the shape of the light spot formed by the projection light of the projection light source 12 projected onto the target traffic sign 16 through the light leakage plate 14 can be ensured to be identical to the shape of the target traffic sign 16.
In one embodiment, the light leakage plate 14 and the target traffic sign 16 are parallel to each other, the vertical distance between the projection light source 12 and the light leakage plate 14 is H, and the vertical distance between the light leakage plate 14 and the target traffic sign 16 is H. Fig. 4 is a diagram of a simple positional relationship of a traffic sign indicating device according to an embodiment of the present application, where a perpendicular point of a plane where the projection light source 12 and the target traffic sign 16 are located is first used as an origin O, any straight line intersecting the origin O on the plane where the target traffic sign 16 is located is taken as an X-axis, a straight line perpendicular to the X-axis on the plane where the target traffic sign 16 is located is taken as a Y-axis, and a straight line passing through the origin O and perpendicular to the plane where the target traffic sign 16 is located is taken as a Z-axis, so as to establish a coordinate system. A coordinate system is established by taking a perpendicular point of a plane where the projection light source 12 and the light leakage plate 14 are located as an origin O ', taking a straight line which passes through the origin O' and is parallel to the X axis on the plane where the light leakage plate 14 is located as an X 'axis, and taking a straight line which passes through the origin O' and is perpendicular to the X 'axis on the plane where the light leakage plate 14 is located as a Y' axis. The target traffic sign 16 is decomposed into line segments or curves, and end points of the line segments or key points of the curves are determined, and the end points of the line segments or the key points of the curves can determine the shape of the target traffic sign 16. The shape of the target traffic sign 16 on the plane of the target traffic sign is illustrated BY a line segment AB, and it is assumed that coordinates of a and B are a (X1, Y1) and B (X2, Y2), respectively, on the plane of the target traffic sign 16, the point a intersects the X axis and the Y axis perpendicularly at AX and AY, respectively, and the point B intersects the X axis and the Y axis perpendicularly at BX and BY, respectively. It is necessary to determine the coordinates of the end points of the line segment a 'B' corresponding to the line segment AB on the plane of the light leakage plate 14, assuming that the coordinates of a 'and B' are a '(x 1', y1 '), B' (x2 ', y 2'), respectively. The point A 'is perpendicularly intersected with the X' axis and the Y 'axis respectively at A' X 'and A' Y ', and the point B' is perpendicularly intersected with the X 'axis and the Y' axis respectively at B 'X' and B 'Y'. Then x1 '═ x1 ° (H/H + H), y 1' ═ y1 ° (H/H + H), x2 '═ x2 ° (H/H + H), y 2' ═ y2 ° (H/H + H), then a 'coordinates are (x1 ° (H/H + H), y1 ° (H/H + H)), B' coordinates are (x2 ° (H/H + H), y2 ° (H/H + H)), and the shape of the light leakage plate 14 matching the shape of the target traffic sign 16 can be determined. In this way, the shape of the light leakage plate 14 can be matched to the shape of any desired traffic sign 16.
As one of the possible embodiments, the plane of the light leakage plate 14 and the plane of the target traffic sign 16 are not parallel to each other, and the installation positions of the projection light source 12 and the light leakage plate 14 are confirmed in advance. The shape of the light leakage plate 14 that matches the shape of the target traffic sign 16 can be confirmed in the following manner.
