Description

  The present invention relates to a lighting device that illuminates a pedestrian crossing or a pedestrian staying space.

  Visual information occupies most of the driving criteria for car drivers. The driver does not make a judgment based on the current visual information, but compares the past information with the current information, estimates the future state, and makes a judgment on the next action to be performed.

  In addition, giving attention on information boards at pedestrian crossings or intersections may result in increased confirmation items for the vehicle in motion, which may distract the driver's attention. It is an aid and effective visual information.

  Illumination includes a vehicle headlamp. However, the effect of illumination by the vehicle headlamp is very different depending on the reflectance of the target object. According to the illumination provided at the intersection or the like, the road surface as the background can be brightened, and the difference in luminance of the object can be clarified. Thereby, visibility can be improved regardless of the reflectance of the object.

  As a conventional lighting device that illuminates a pedestrian crossing, for example, there is a device that illuminates only when it is detected that a person is present only in a pedestrian crossing as an illumination range. In addition, as another example, there is one that is interlocked with the state of the traffic light, but it performs illumination only when a pedestrian signal can travel. In addition, there are some which decide whether or not to illuminate the pedestrian crossing only by the ambient illuminance. All of these only illuminated the pedestrian crossing.

  However, the conventional techniques described above have the following problems.

(1) When only the pedestrian crossing is illuminated at the same time that the signal can travel, the driver first sees the signal and enters the intersection, so the discovery of the pedestrian is delayed. The discovery of pedestrians who are about to enter a pedestrian crossing, especially in a pedestrian space, is delayed.

(2) If only the pedestrian crossing is illuminated, it is not preferable to illuminate during the time when the signal is prohibited from traveling. This is because if the lighting is installed at an angle that illuminates only the pedestrian crossing, the lighting is applied to a vehicle that is stopped or the like due to the angle relationship, and the driver becomes dazzled.

(3) It cannot be said that only the pedestrian staying space is illuminated. This makes it difficult to notice the presence of pedestrians waiting for traffic lights.

(4) When only the pedestrian crossing is illuminated, the pedestrian staying space outside the pedestrian is not illuminated, the movement of the pedestrian cannot be captured continuously, and the discovery of the pedestrian is delayed.

  The present invention has been made paying attention to such problems of the prior art, and illuminates the pedestrian residence space in the pedestrian residence space where a pedestrian is present before starting to cross the pedestrian crossing. It aims at providing the illuminating device which enabled it.

The lighting device is characterized in that the lighting time of the person staying space lighting means (100) can be extended, and the extended time is controlled until the vehicle signal (20) on the crossing side can proceed at the longest. .

[ 3 ] The pedestrian crossing illumination means (110) and the pedestrian staying space illumination means (100) are arranged to illuminate from the inside to the outside of the intersection [1] or [1] [2] The lighting device according to item.

The present invention operates as follows.
The lighting device of the present invention illuminates traffic by illuminating a pedestrian crossing (220) or a pedestrian residence space (210) where a pedestrian may be waiting before starting to cross the pedestrian crossing (220). Safety is ensured by smooth operation.

When the night detection means (40) detects that it is nighttime, the pedestrian staying space lighting control means (70) turns on the pedestrian staying space lighting means (100), thereby the pedestrian staying space (210). Illuminate pedestrians in the street. This allows the driver to easily determine whether or not there is a person trying to cross the pedestrian crossing (220). When the night detection means (40) detects that it is nighttime, and the signal is ready to travel or is in a state of caution, the pedestrian crossing illumination control means (80) turns on the pedestrian crossing illumination means (110). Thus, both the pedestrian staying space (210) and the pedestrian crossing (220) can be illuminated. Thereby, the pedestrian in the pedestrian staying space (210) or the pedestrian crossing (220) can be continuously illuminated. Here, the signal is a pedestrian signal (10) for a pedestrian crossing a predetermined pedestrian crossing or a vehicle signal (20) directed in the same direction as the pedestrian signal (10) .

  Since the lighting device of the present invention lights the pedestrian staying space lighting means (100) and the pedestrian crossing lighting means (110) on the condition that there is a pedestrian, the driver can confirm that there is a pedestrian by the lighting. It becomes possible to confirm.

  Since the pedestrian staying space lighting means (100) and the pedestrian crossing lighting means (110) are turned on under the condition that the vehicle is present, the driver can confirm the presence or absence of a pedestrian by the lighting.

  The lighting device of the present invention is a pedestrian crossing illumination means (110) and a pedestrian crossing lighting means (110) when it is detected that there is a pedestrian and a right turn car at night and the signal is capable of traveling or is in a state of attention to traveling. The pedestrian staying space illumination means (100) is turned on. By being able to illuminate both the pedestrian residence space (210) and the pedestrian crossing (220), the pedestrian can be illuminated continuously. In addition, even if the signal is in a state where travel is prohibited, the lighting time of the pedestrian crossing illumination means (110) and the pedestrian staying space illumination means (100) can be extended, so that pedestrians and signals that are not in time for crossing. It is possible to illuminate pedestrians who are trying to cross the road. Since the extension time is controlled so that the vehicle signal (20) can proceed at the longest, the glare can be prevented from being felt when the vehicle starts to pass.

  Furthermore, the pedestrian crossing lighting means (110) and the pedestrian staying space lighting means (100) are arranged so as to illuminate from the inside to the outside of the intersection, thereby reducing the lighting on the vehicle. The driver can be less distracted.

  When the illumination means capable of illuminating both the pedestrian crossing (220) and the pedestrian staying space (210) detects nighttime, it illuminates both the pedestrian crossing (220) and the pedestrian staying space (210). Thus, both the pedestrian crossing (220) and the pedestrian staying space (210) can be illuminated during the night by a single lighting means.

  According to the lighting device according to the present invention, the pedestrian staying space can be illuminated, so that the driver can easily check whether there is a pedestrian who is going to cross the pedestrian crossing.

  Since both the pedestrian staying space and the pedestrian crossing can be illuminated, the pedestrian can be illuminated continuously. This allows the driver to easily identify pedestrians in the pedestrian crossing and pedestrian staying space within the intersection, and pedestrians suddenly appear on the pedestrian crossing even though there are pedestrians in the pedestrian staying space. It doesn't look like it.

  Since the pedestrian crossing lighting means and the pedestrian staying space lighting means are arranged so as to illuminate from the inside to the outside of the intersection, glare to the driver can be reduced.

  Since it is turned on by detecting that there is a pedestrian, it can be confirmed that there is a pedestrian if there is a pedestrian. It is possible to eliminate such waste. Similarly, it is lit when it senses that there is a right turn car, so it can easily check whether there is a pedestrian in the right turn car. Waste can be saved.

  Furthermore, even if the signal is prohibited from proceeding, the lighting time can be extended, so that it is possible to illuminate pedestrians who have not crossed in time or pedestrians ignoring the signal, Traffic safety can be achieved. In addition, the extension time of the lighting time is limited until the vehicle signal can travel, so that there is an effect that the driver does not feel glare due to the lighting when the vehicle starts to pass.

  Since both the pedestrian crossing and the pedestrian staying space can be illuminated during the night by one lighting means, the pedestrian can be illuminated continuously. Furthermore, the illumination means can be made inexpensive and its control is simplified.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. Each figure describes one embodiment of the present invention. FIG. 1 shows a conceptual block diagram of an embodiment of the present invention. As shown in FIG. 1, the lighting apparatus according to the present embodiment is connected so that a signal state can be input from the pedestrian signal 10 and the vehicle signal 20 to the signal input means 30. The signal input means 30, the night detection means 40, the pedestrian detection means 50, and the vehicle detection means 60 are connected to a pedestrian staying space illumination control means 70, a pedestrian crossing illumination control means 80, and an illumination extension control means 90, respectively. The pedestrian residence space illumination means 100 is connected to the pedestrian residence space illumination control means 70 and the illumination extension control means 90. The pedestrian crossing illumination unit 110 is connected to the pedestrian crossing illumination control unit 80 and the illumination extension control unit 90. The pedestrian staying space lighting control means 70, the pedestrian crossing lighting control means 80, and the lighting extension control means 90 are in response to information from the signal input means 30, night detection means 40, pedestrian detection means 50 or vehicle detection means 60, respectively. The lighting and extinguishing of the pedestrian staying space lighting means 100 or the pedestrian crossing lighting means 110 are controlled.

  The pedestrian signal 10 and the vehicle signal 20 transit between the states of “Advanceable”, “Progressive attention”, and “Progression prohibited”, and the signal input unit 30 controls the pedestrian stay space lighting control unit 70 and the pedestrian crossing lighting control. This is transmitted to the means 80 and the illumination extension control means 90. The pedestrian staying space lighting control means 70, the pedestrian crossing lighting control means 80, and the lighting extension control means 90 are a signal indicating whether the signal is from the signal input means 30, whether it is night time from the night detection means 40, walking A signal indicating whether or not there is a pedestrian from the person detecting means 50 and a signal indicating whether or not there is a vehicle from the vehicle detecting means 60 are received and comprehensively determined. As a result of the determination, the pedestrian staying space lighting control means 70 controls whether or not the pedestrian staying space lighting means 100 is lit, and the pedestrian crossing lighting control means 80 determines whether or not the pedestrian crossing lighting means 110 is lit. Control. The lighting extension control means 90 controls the lighting time of the pedestrian staying space lighting means 100 or the pedestrian crossing lighting means 110 to be extended.

  Here, “progressable” generally refers to a blue light in Japan, and more specifically, “pedestrians can travel. Cars (except light vehicles) and trams , You can go straight, turn left or turn right. " “Progressive attention” generally means a yellow light in Japan, or a blinking blue light in a pedestrian traffic light. More specifically, “Pedestrians must not start crossing, and pedestrians that are crossing must either immediately finish crossing or stop crossing and turn back. However, if you are approaching the stop position when the signal turns yellow and you cannot stop safely, you can proceed as it is. " Means "Pedestrians must not begin to cross, and pedestrians that are crossing must either immediately finish crossing or stop crossing and turn back." “Prohibition” refers generally to red lights in Japan, and more specifically, “Pedestrians must not cross. Cars and trams should not proceed beyond the stop. Means.

  The pedestrian staying space lighting control means 70 is (1) connected only to the night detection means 40, (2) connected to the signal input means 30 and the night detection means 40, and (3) night time. When connected to detection means 40 and pedestrian detection means 50, (4) When connected to night detection means 40 and vehicle detection means 60, (5) Signal input means 30, night detection means 40 and pedestrian When connected to the sensing means 50, (6) When connected to the signal input means 30, night detection means 40, and vehicle sensing means 60, (7) Night detection means 40, pedestrian sensing means 50, and vehicle detection. When connected to the means 60, (8) it may be connected to the signal input means 30, the night detection means 40, the pedestrian detection means 50, and the vehicle detection means 60.

  The pedestrian crossing lighting control means 80 is (1) when connected to the signal input means 30 and the night detection means 40, (2) when connected to the night detection means 40 and the pedestrian detection means 50, (3) When connected to night detection means 40 and vehicle detection means 60, (4) When connected to signal input means 30, night detection means 40 and pedestrian detection means 50, (5) Signal input means 30 and night When connected to detection means 40 and vehicle detection means 60, (6) When connected to night detection means 40, pedestrian detection means 50 and vehicle detection means 60, (7) Signal input means 30 and night detection In some cases, the means 40, the pedestrian sensing means 50 and the vehicle sensing means 60 are connected.

  The illumination extension control means 90 is (1) connected only to the signal input means 30, (2) when connected to the signal input means 30 and the night detection means 40, and (3) walking with the signal input means 30. When connected to the pedestrian detection means 50, (4) When connected to the signal input means 30 and the vehicle detection means 60, (5) Connected to the signal input means 30, night detection means 40 and pedestrian detection means 50 (6) When connected to the signal input means 30, night detection means 40, and vehicle detection means 60, (7) Connected to the signal input means 30, pedestrian detection means 50, and vehicle detection means 60. (8) The signal input means 30, the night detection means 40, the pedestrian detection means 50, and the vehicle detection means 60 may be connected.

  Next, the operation will be described. When the night detection means 40 detects that it is nighttime, the pedestrian staying space illumination control means 70 receives the detection and controls to turn on the pedestrian staying space illumination means 100. Thus, a pedestrian in the pedestrian staying space 210 can be illuminated, and the driver can easily determine whether or not there is a person trying to cross the pedestrian crossing 220. When the night detection means 40 detects that it is nighttime, the pedestrian crossing lighting control means 80 receives from the signal input means 30 that the pedestrian signal 10 or the vehicle signal 20 can be advanced or is in a state of attention to progress. Turns on the pedestrian crossing illumination means 110. Thus, both the pedestrian staying space 210 and the pedestrian crossing 220 can be illuminated, and the pedestrian staying in the pedestrian staying space 210 or the pedestrian crossing 220 can be continuously illuminated.

  In addition, this lighting device further indicates that when the pedestrian staying space lighting control means 70 or the pedestrian crossing lighting control means 80 receives that the pedestrian detection means 50 has detected a pedestrian, that is, there is a pedestrian. As the AND condition, since the pedestrian staying space lighting unit 100 and the pedestrian crossing lighting unit 110 are turned on, the driver can confirm that there is a pedestrian by the lighting.

  This illuminating device has a further AND condition when the pedestrian staying space lighting control means 70 or the pedestrian crossing lighting control means 80 receives that the vehicle sensing means 60 senses the presence of the vehicle, that is, the presence of the vehicle. Since the pedestrian staying space lighting unit 100 and the pedestrian crossing lighting unit 110 are turned on, the driver can check the presence or absence of a pedestrian by the lighting.

  In this lighting device, it is detected that the night detection means 40 is at night, the pedestrian detection means 50 has detected a pedestrian, the vehicle detection means 60 has detected that there is a vehicle, the pedestrian signal 10 Alternatively, when the pedestrian staying space lighting control means 70 or the pedestrian crossing lighting control means 80 receives through the signal input means 30 that the vehicle signal 20 is capable of proceeding or attention to traveling, that is, at night, the pedestrian and right turn When it is detected that there is a vehicle and the signal is in a state where the vehicle can travel or is in a state of attention to traveling, the pedestrian staying space lighting unit 100 and the pedestrian crossing lighting unit 110 are turned on. As a result, both the pedestrian staying space 210 and the pedestrian crossing 220 can be illuminated, and the pedestrian can be illuminated continuously. In addition, when the lighting extension control means 90 receives through the signal input means 30 that the pedestrian signal 10 or the vehicle signal 20 is in a state where travel is prohibited, the pedestrian staying space lighting means 100 and the pedestrian crossing lighting means 110 The lighting time can be extended. As a result, it is possible to illuminate pedestrians who are not in time for crossing and pedestrians who are ignoring signals and crossing. Since the extension time is controlled so that the vehicle signal can proceed at the longest, glare can be prevented when the vehicle starts to pass.

  Further, the pedestrian staying space lighting means 100 and the pedestrian crossing lighting means 110 are arranged so as to illuminate from the inside to the outside of the intersection, thereby reducing the lighting on the vehicle and dazzling the driver. Can be reduced.

  FIG. 2 is a diagram for explaining a lighting situation when the progress is prohibited. Specifically, it is a diagram for explaining how the pedestrian staying space lighting means 100 and the pedestrian crossing lighting means 110 are attached at the intersection, and lighting when the pedestrian signal 10 is prohibited from proceeding at night. . The pedestrian staying space 210 is a place where a pedestrian waiting to cross the pedestrian crossing 220 is waiting. Of course, the place in front of the pedestrian crossing 220 is a pedestrian staying space 210. The pedestrian staying space illumination means 100 is disposed at a position that illuminates the pedestrian staying space 210. The pedestrian crossing illumination means 110 is disposed at a position that illuminates the pedestrian crossing 220. Since FIG. 2 shows the case of nighttime, it is detected that the nighttime detection means 40 is nighttime, and the pedestrian staying space lighting control means 70 detects that the pedestrian staying space lighting means 100 is walking according to the detection signal. The person staying space 210 is controlled to be illuminated. In this case, since the signal input means 30 informs the pedestrian crossing lighting control means 80 that the pedestrian signal 10 or the vehicle signal 20 is prohibited from proceeding, the pedestrian crossing lighting control means 80 does not cross the pedestrian crossing lighting means 110. Is turned off, that is, not turned on.

  It is to be noted that the vehicle signal 20 is prohibited from proceeding, and the automobile 230 moving upward from the bottom in FIG. 2 is stopped in front of the pedestrian crossing 220, and the automobile 230 is about to turn right. At this time, since the pedestrian staying space 210 is illuminated by the pedestrian staying space illumination means 100, it can be confirmed to the driver of the automobile 230 that there is a pedestrian in the pedestrian staying space 210.

  FIG. 3 is a diagram for explaining a lighting situation in a case where it is possible to proceed. Specifically, lighting of the pedestrian staying space lighting unit 100 and the pedestrian crossing lighting unit 110 when the pedestrian signal 10 and the vehicle signal 20 are changed from the state of prohibition of travel in FIG. FIG. When the pedestrian signal 10 or the vehicle signal 20 changes from the state where travel is prohibited to the state where travel is possible, the signal input means 30 informs that the pedestrian signal 10 or the vehicle signal 20 has changed from progress prohibited to the state where travel is possible. The pedestrian crossing illumination control unit 80 controls the pedestrian crossing illumination unit 110 to light up. By lighting up in this way, both the pedestrian staying space 210 and the pedestrian crossing 220 are illuminated, and whether the driver of the car 230 has a pedestrian in the pedestrian staying space 210 or in the pedestrian crossing 220. This can be easily recognized.

  FIG. 4 is a diagram three-dimensionally showing the positions where the pedestrian sensing means 50 and the vehicle sensing means 60 are attached at the intersection. Since the pedestrian detection means 50 detects whether or not there is a pedestrian in the pedestrian staying space 210, it is installed in the vicinity of the pedestrian staying space 210. More specifically, it is provided on the lower side of a pole with a pedestrian traffic light, and can detect a person with infrared rays or the like. Since the vehicle sensing means 60 senses whether a right turn car is present or not, it is installed near the position where the right turn car stops in front of the pedestrian crossing 220. More specifically, it is provided above the stop line, which is the inflow path of the intersection and before the intersection of the right turn lane where the right turn vehicle stops, and the vehicle can be detected by ultrasonic waves or the like.

  The night detection means detecting that it is night is performed, for example, by measuring ambient illuminance or detecting night by time or the like.

  FIG. 5 is a diagram illustrating a position where the pedestrian crossing illumination unit 110 is attached. The pillar 111 is a pillar to which the pedestrian crossing illumination means 110 is attached. The pole 111 may substitute a pole with a pedestrian signal 10 or a vehicle signal 20.

  The direction of the pedestrian crossing illumination means 110 is set to be as much as possible with respect to the traveling direction of the vehicle. This is because the object becomes a silhouette when the illumination is illuminated from the opposite direction of the traveling direction of the vehicle.

  By limiting the range of illumination of the pedestrian crossing illumination means 110, it is possible to minimize light pollution on surrounding private houses and farmland. Ordinary road lighting is installed at heights of 8 m, 10 m, and 12 m, and is suitable for illuminating the whole. On the other hand, it is possible to perform concentrated illumination by setting the illumination mounting position of the illumination apparatus lower than that of general illumination and shortening the distance from the light source to the illuminated position.

  Generally, people feel glare when there is a strong light source within an angle of 30 degrees above and below the line of sight, and it can be said that there is little effect on pedestrians if illumination is performed from outside this range. The height of the pillar 111 or the height at which the pedestrian crossing illumination means 110 is installed is adjusted in consideration of the width of the road and the glare to the pedestrian. That is, since the pedestrian crossing illumination means 110 is installed at both ends of the pedestrian crossing 220, it is only necessary to illuminate half of the length of the pedestrian crossing 220 (the width of the road). As a method of adjustment, it is possible to respond by changing the angle of the louver provided in the pedestrian crossing illumination means 110 or by a variable louver that suppresses illusion. In addition, the pedestrian staying space lighting unit 100 is installed at a position substantially the same as the pedestrian crossing lighting unit 110 so that the pedestrian does not feel glare.

  Moreover, the directions of the pedestrian crossing illumination unit 110 and the pedestrian staying space illumination unit 100 are set so as to perform illumination from the inside to the outside of the intersection. More specifically, as shown in FIG. 3 and FIG. 4, pedestrian staying space lighting means 100 and pedestrian crossing lighting means 110 are arranged at the corners of the four corners of the intersection, and the direction of the lighting is outside the center of the intersection. To illuminate. As a result, it is possible to reduce lighting on the automobile 230 in front of the pedestrian crossing 220 and to reduce the dazzling of the driver of the automobile 230.

  Intersections or pedestrian crossings such as those in urban areas are bright in surroundings, so the glare of lighting is relatively uninteresting, but at intersections or pedestrian crossings away from urban areas, the surroundings are dark, so the same illumination will make you feel the glare strongly . Therefore, the light source (light bulb) of the luminaire can be selected in order to illuminate according to the situation around the intersection or pedestrian crossing. By setting the illuminance by replacing the bulb, the function of the luminaire can be simplified and made inexpensive. In addition, when LED type illumination is used, the illuminance is set by the number of elements.

  Next, lighting control according to the state of the traffic light will be described. At night, the lighting control of the pedestrian crossing illumination means 110 according to the state of the pedestrian signal 10 or the vehicle signal 20 is prohibited to proceed with the pedestrian signal 10 (so-called red), can proceed with the vehicle signal 20 (so-called blue), and the vehicle signal 20 This is performed using any one or more of prohibition of progress (so-called red). Since it is limited to information on the state of traffic lights, circuit design and construction can be simplified, and installation at existing intersections can be performed easily. FIG. 6 is a diagram illustrating the lighting period. Specifically, it is a diagram showing a period during which the pedestrian crossing illumination means 110 is lit according to the state of the pedestrian signal 10 and the vehicle signal 20. The pedestrian crossing illumination control unit 80 controls lighting of the pedestrian crossing illumination unit 110 according to any one of (Logic 1), (Logic 2), and (Logic 3) described below.

  (Logic 1) A lighting condition for the pedestrian crossing illumination unit 110 is set to a time other than the prohibition time (other than red) of the pedestrian signal 10. That is, the pedestrian crossing illumination means 110 is turned on during the time when the pedestrian signal 10 can travel (blue) and during the time when the pedestrian signal 10 travels carefully (flashing blue). A lighting period A in FIG. 6 shows this control method.

  (Logic 2) The travelable (blue) time of the vehicle signal 20 is set as the lighting condition of the pedestrian crossing illumination unit 110. In other words, the time when the pedestrian signal 10 can travel (blue), the time when the pedestrian signal 10 progresses attention (flashing blue), the pedestrian signal 10 is prohibited from traveling (red), and the vehicle signal 20 can travel (blue). ) The pedestrian crossing illumination means 110 is turned on during the time (approximately 2 seconds). The lighting period B in FIG. 6 shows this control method.

  (Logic 3) The lighting condition of the pedestrian crossing illumination means 110 is set to a time other than the travel inhibition time (other than red) of the vehicle signal 20. In other words, the time when the pedestrian signal 10 can travel (blue), the time when the pedestrian signal 10 progresses attention (flashing blue), the pedestrian signal 10 is prohibited from traveling (red), and the vehicle signal 20 can travel (blue). ), And the pedestrian signal 10 is turned on during the time (about 3 seconds) when the pedestrian signal 10 is prohibited from progressing (red) and the vehicle signal 20 is ahead of attention (yellow) (about 3 seconds). The lighting period C in FIG. 6 shows how this control is performed.

  The situation of (Logic 2) and (Logic 3) is not safe for pedestrians, but it is safer for people who have not been able to cross the road or who have neglected signals. is there.

  In addition to the above, the extension time can be provided by installing an illumination extension control means 90, for example, a timer. This timer can be finely set (such as setting in units of 1 second). However, the lighting time is extended until the vehicle signal 20 on the crossing side can travel (blue). This is to prevent glare from lighting when the vehicle on the intersection starts to pass.

  Next, as this improvement, when the night detection means 40 performs night determination and is determined to be night, the pedestrian crossing illumination means 110 is only detected when a pedestrian or a right turn car is detected during the lighting conditions described above. It is also possible to light up. FIG. 7 is a time chart showing lighting conditions when a sensing signal is added. In FIG. 7, A represents the state of the vehicle signal 20, B represents the state of the pedestrian signal 10, and C represents that the lighting condition is satisfied by the above (logic 2). D and E represent cases where the pedestrian sensing means 50 or the vehicle sensing means 60 senses a pedestrian or a right turn vehicle.

  When the lighting condition is satisfied by the above (Logic 2) and the pedestrian detection means 50 or the vehicle detection means 60 detects a pedestrian or a right turn car (D in FIG. 7), the pedestrian crossing illumination means 110 is turned on. When the lighting condition is no longer satisfied (D in FIG. 7), the pedestrian crossing illumination unit 110 is extinguished to clear the sensing condition. If there is a sense when the lighting condition is not satisfied (E in FIG. 7), the pedestrian crossing illumination means 110 is turned on when the lighting condition is satisfied next time.

  The same control can be performed even when the lighting condition of (Logic 1) or (Logic 3) is satisfied as well as the above (Logic 2).

  FIG. 8 is a diagram for explaining a region where the vehicle sensing means 60 senses. When the vehicle sensing means 60 performs vehicle sensing, a sensor (for example, an image-type vehicle sensor) capable of sensing the vehicle over a wide area is used, so that it is turned on faster than an ultrasonic vehicle sensor that senses in a narrow range. be able to. When an ultrasonic vehicle sensor is used as the vehicle sensing means 60, the vehicle can be sensed just before the stop line as shown in FIG. When an image type vehicle detector is used as the vehicle detection means 60, the detection can be performed when the vehicle enters the right turn lane as shown in FIG. As a result, the pedestrian crossing illumination means 110 can be quickly turned on, and traffic safety can be further improved. Further, as shown in FIG. 8 (3), even if the vehicle stops beyond the stop line, the image type vehicle detector can detect a right turn vehicle, and the pedestrian signal 10 or the vehicle signal 20 The pedestrian crossing illumination means 110 can be turned on by the next signal that can travel.

  The pedestrian crossing illumination means 110, which is illumination for pedestrians waiting for crossing, is controlled to be lit regardless of the state of the traffic lights when a pedestrian or vehicle is detected at night, and the pedestrian crossing illumination means 110 and Control is performed so that the light is extinguished according to the signal state of the pedestrian signal 10 of the corresponding pedestrian crossing 220. Since the lighting to the pedestrian staying space 210 that does not affect the driver of the vehicle due to the lighting, it can be turned on regardless of the traffic light state, and the presence of the pedestrian can be confirmed even for the vehicle driver who has stopped. Can be informed and safer.

  When the pedestrian sensing means 50 is turned on by pedestrian detection, it is possible to strongly inform the driver of the presence of the pedestrian due to the difference from when it is not lit.

  When the vehicle sensing means 60 turns on the vehicle when the vehicle is detected, the safety can be improved because the driver can always confirm the presence or absence of a pedestrian when there is a right turn vehicle.

  In addition, only lighting of the pedestrian crossing illumination means 110 during crossing is dangerous because it causes light and darkness in the pedestrian crossing 220. Therefore, when the pedestrian crossing illumination means 110 is turned on, the pedestrian stay space illumination control means 70 and the pedestrian crossing illumination control means 80 are controlled so that the pedestrian stay space illumination means 100 is always turned on.

  FIG. 9 is a diagram for explaining lighting conditions of the pedestrian staying space lighting unit 100. FIG. 9 (1) shows a case where the night detection means 40 detects that the night is night, the pedestrian signal 10 and the vehicle signal 20 are prohibited from proceeding, and the pedestrian detection means 50 detects a pedestrian. Or when the vehicle detection means 60 detects a right turn vehicle, it controls so that the pedestrian residence space illumination means 100 is turned on, and thereby the pedestrian residence space 210 is illuminated. FIG. 9 (2) shows a case where the night detection means 40 detects that it is night, and when the pedestrian signal 10 and the vehicle signal 20 can travel and the pedestrian crossing illumination means 110 is turned on, Although the pedestrian is not in the pedestrian staying space 210, the pedestrian staying space illumination means 100 is turned on so as not to cause light and darkness in the pedestrian crossing 220. FIG. 9 (3) shows a case where the night detection means 40 detects that it is night, and the pedestrian signal 10 and the vehicle signal 20 are prohibited from proceeding, but the pedestrian detection means 50 does not detect a pedestrian. When the vehicle sensing means 60 does not sense a right turn vehicle, the pedestrian staying space illumination means 100 is controlled not to be lit.

  As an example of lighting used for the pedestrian staying space lighting unit 100 or the pedestrian crossing lighting unit 110, LED type lighting may be used. The function does not suddenly deteriorate like a bulb break, and it is long-life and energy-saving, making it more suitable for safety and maintenance costs than the bulb type. Furthermore, if the direction of the LED elements can be changed individually, the illumination range can be freely selected, which is more effective.

  In the present embodiment, the pedestrian staying space lighting means 100 and the pedestrian crossing lighting means 110 are shown as having two lights. Both may be illuminated. In this case, the pedestrian crossing / pedestrian staying space illumination means 1000, the night detection means 40, and the lighting control means are provided.

  FIG. 10 is a diagram for explaining one lighting device that illuminates the pedestrian crossing 220 and the pedestrian staying space 210. The pedestrian crossing / pedestrian staying space lighting unit 1000 has both lighting functions of the pedestrian staying space lighting unit 100 and the pedestrian crossing lighting unit 110 described above. That is, the lighting range of the pedestrian / pedestrian staying space illumination means 1000 is not only on the pedestrian crossing 220 but also the pedestrian crossing 220 and the pedestrian staying space 210. The lighting control means for controlling the lighting of the pedestrian / pedestrian staying space lighting means 1000 is a pedestrian staying space lighting control means 70, a pedestrian staying space lighting control means 80, or a pedestrian staying space lighting control means 70 and a pedestrian crossing lighting control. Both functions of the means 80 are provided. As a result, the driver of the car 230 can find a pedestrian in the pedestrian crossing 220 earlier and can drive safely than when only the pedestrian crossing 220 is illuminated. For this reason, the installation position of the pedestrian crossing / pedestrian staying space lighting means 1000 is near the end inside the intersection of the pedestrian crossing 220. The lighting conditions at that time are when the night. The lighting control means controls the lighting of the pedestrian crossing / pedestrian staying space illumination means 1000 when the night detection means 40 detects that it is nighttime.

  Further, by providing the signal input means 30, the pedestrian sensing means 50, and the vehicle sensing means 60, the lighting condition can be (1) not only at night, but also (2) the signal state can proceed at night. Or in the case of progress attention, (3) In addition to the conditions of (2), if there are pedestrians, (4) In addition to the conditions of (2), if there is a right turn car, or (5) (2) In addition to the conditions, when there is a pedestrian and a right turn car, either of them can be adopted. The lighting control unit controls lighting of the pedestrian crossing / pedestrian staying space lighting unit 1000 according to each information of the signal input unit 30, the night detection unit 40, the pedestrian detection unit 50, and the vehicle detection unit 60.

  The pedestrian staying space lighting control means 70, the pedestrian crossing lighting control means 80, and the lighting extension control means 90 can be realized by a hardware circuit, but can also be realized by controlling using a computer. In the case of using a computer, the control method is realized by a program.
