Abstract

The present invention relates to a pedestrian traffic light installed in a crosswalk. Conventional pedestrian traffic lights can be seen well across the street, but not on the driver's or pedestrian's side (i.e. side) that is about to turn right.
In general, when there are large vehicles in the inner lane at four streets, drivers who turn right or pedestrians cannot see the pedestrian signal at all.
In order to overcome the above disadvantages, the present invention is to add an auxiliary signal to the existing pedestrian traffic lights or to specifically design the main traffic lights, to prevent traffic accidents, and further to provide psychological comfort to all drivers and pedestrians. . In particular, when the auxiliary lamps are not additionally installed, energy is added to the main signal lamp, or the shape and layout of the main signal lamp (special way of installing the main signal lamp) is specially designed to produce the same effect as when installing the auxiliary lamp. You can also save money.

Description

A pedestrian signal lamp with a ramp arrangement of traffic light}

The present invention relates to a pedestrian traffic light 1 installed in a crosswalk (FIG. 1). In the case of the conventional pedestrian traffic light, the traffic light can be seen well across the street, but if you want to see the signal of the pedestrian standing on your side, you have to reach out to the road and turn your head up, and you can't see it from the side.

As mentioned in the above technical field, the pedestrian traffic light 1 on the opposite side is well visible, but the reason why the traffic light on the side where the pedestrian itself (or the driver who drives the outermost lane) cannot be seen from the side is as follows. This is because the lampshade 104 is located at the edge of the driveway and covers the rainwater 104 to prevent rainwater (FIG. 1). Moreover, the shade 104 is painted in a dark color so that rust and dust are not easily seen (FIG. 1).

Typically at 4 distances the vehicle driver can make a right turn in the outermost lane, regardless of the forward signal. If there is a large truck or bus in the lane just inside the outermost lane, drivers who want to turn right are often wondering if the pedestrian signal 1 is green 102 or red 106 (Figure 2). This frustration also applies to pedestrians (Figure 2c). If the opposite pedestrian traffic light (1) is obstructed by a large vehicle, it can be determined whether or not to jump over by looking at the pedestrian signal on the side of the pedestrian itself, the reason for not being able to determine the shade (104) covered with the traffic light (1) This is because the light is hidden and cannot be seen from the side (2).

Although it is often necessary to look at the pedestrian traffic light 1 from the side 2 in this way, the ordinary pedestrian traffic light 1 is difficult to check the light at the side, not to mention during the day (at the advanced countries) At the height of the pedestrian traffic light, an auxiliary traffic light is installed so that it can be seen from the side, since the traffic light is for the driver who turns right, the signal color of this is the opposite of the color of the crosswalk signal.)

As mentioned in the background art, on the basis of the analysis of the shape of the pedestrian traffic light which is widely used (FIG. 1) and the traffic signal system (FIGS. 2a and 2b), the following problems are solved by the present invention. Can be summarized as follows:

First, despite the fact that the driver 202 in the far lane may turn right, regardless of the signal 203 in front of the vehicle at four distances, if a large vehicle is waiting for a signal inside, Often it is not possible to determine whether pedestrians cross. This frustration is the same in the case of the pedestrian 201, but if the opposite pedestrian traffic lights (1, 206) is obstructed by a large vehicle, the pedestrian 201 walking along the sidewalk toward the crosswalk, the pedestrian signal (the side of the side) 207) can be judged whether or not to run.

<Example of situation for traffic signal system>

□ If the forward signal is red 203 and the pedestrian signals 206 and 207 are green:

  At 4 distances, the forward signal is red (stop, 203), and when both transverse signals are green (going, 204, 205), the pedestrian signal toward the right-turn driver 202 is the green (207) signal. 2a degrees).

□ If the forward signal is red 203 and the pedestrian signals 206 and 207 are red:

  At 4 distances, if the forward signal is red 203 and the transverse signals are all left turn (or right turn at 3 distances) signals 208 and 209, the pedestrian signal 207 toward the right turn driver 202 is a red signal. (Figure 2b).

<Inconvenient situation for normal traffic light>

□ If the pedestrian traffic light is hidden, does the crosswalk signal turn red? green ?

 If the opposite pedestrian traffic light 206 is obscured by a large vehicle (FIGS. 2A and 2B), in the position of the driver 202 trying to turn right or the pedestrian 201 proceeding along the sidewalk but eventually crossing it, the pedestrian signal Is it red? Is it green? Very curious.

Unfortunately, the ordinary pedestrian traffic light 1 is designed with a shade 104 on it so that it cannot be seen at all (from the perspective of the right-turn driver 202 or the pedestrian 201) (FIG. 1). Therefore, the method which can confirm the signal state (red or green) of the pedestrian traffic light 207 of the side where these are located from the side.

Second, in advanced countries, an auxiliary signal light is installed at the middle height of the pedestrian traffic light 1 so that it can be seen from the side, but this is for a right-turn driver, and the signal color is opposite to the color of the pedestrian signal. It is designed not to be confused with this conceptually, but the design and manufacturing method for the pedestrian traffic light (1) which can be seen from the side is presented.

Through the present invention, the solving means that can overcome the problems with the conventional pedestrian traffic light (1) is as follows.

First, consider the second problem, the signal of the auxiliary signal lamp installed in the middle height of the pedestrian traffic light (1) is basically opposite to the pedestrian signal, and for the driver, the installation height is a position that must be seen in the car. However, this position is likely to be hidden by other pedestrians and roadside trees. Therefore, the present invention is conceptually completely separated from the auxiliary signal lamps of the developed countries, and is designed so that there is no confusion from the standpoint of the pedestrian and the right-turn driver 202. Therefore, a method (tool) that can be seen from the side is formed near the signals 104 and 105, not the middle height of the pedestrian traffic light (1) pillar, but the color of the side signal is consistent with the color of the pedestrian signal in compliance with the pedestrian priority principle. Let's do it.

Second, the present invention is designed in consideration of the duality (straight and diffraction) of the traffic light, the material requirements of the material comply with the 'LED traffic light standard (Road Traffic Safety Management Corporation)'.

In general, the vehicle driver may turn right in the outermost lane regardless of the forward signal in the straight direction. If a large vehicle is in the lane just inside the outermost lane, the right-hand drivers are very curious about the state of the crosswalk signal. If it's red, you can turn right at ease, but if it's green, you must stop because people are crossing. The same is true of busy pedestrians walking in India. If you want to cross, even if you run, you must see the traffic light on your side from the side, but you cannot. Although there are many cases where the crosswalk traffic light must be viewed from the side, the current situation of installing the pedestrian traffic light is difficult to see at night, even at night.

The present invention is designed to determine the signal of the pedestrian traffic light (1) from the side (3 to 7), if applied, it can prevent traffic safety accidents in advance, to all drivers and pedestrians It can provide psychological convenience. In particular, in the case of not providing a separate auxiliary signal (Figs. 4 to 7), it is possible to save energy, and furthermore, if the embodiment shown in Figs. Even if the signal change can be accurately judged, the inconvenience of such people will disappear.

The present invention relates to a pedestrian traffic light (1) installed on the crosswalk, the right turn driver 202 or pedestrian 201 is made so that you can check the lights of the pedestrian traffic lights from the side. As derived from the above-mentioned problem solving means, the present invention is a side view device, as shown in FIG. 3, the side assistance lamp 303 near the main signal light 302, not the middle height of the pedestrian traffic light. ), But in accordance with the pedestrian priority principle, the side side light 303 color of the side coincides with the color of the main traffic light 302. This emphasizes that the right-turn driver 202 must recognize the change in signal from the pedestrian 201's position, not from his (driver's) position.

In compliance with the basic principles, five embodiments of the present invention have been presented. The configuration, function, and characteristics thereof will be described as follows.

Embodiment 1 (a pedestrian traffic light 3 provided with side assistance lamps) is shown in FIG. 3, which is provided with a side assist light 303 on the side of a normal pedestrian traffic light 3. As shown in FIG. Side assist light 303 is configured as a red traffic light and a green traffic light on the upper and lower, respectively, is installed only on the side visible to the driver. This is because there is no meaning of the side light (303) on the opposite side, because this is the same position for pedestrians. The ON-OFF cycle of the side assistance lamp 303 coincides with the cycle of the main traffic light 302 and is installed at the same height as the main traffic light 302 in the sense of emphasizing that it is a signal for pedestrians. In addition, the side light 303 is formed around the side of the side light (303) having the same size and shape of the auxiliary light cover 304, the side light (303), coupled to the side light (303), the auxiliary light A mirror film is formed on the inner surface of the cover 304. A reflection plate 307 acting as a mirror is formed inside the auxiliary light cover 304, and at least one light emitting diode 306 is installed in front of the reflection plate 307, and the light emitting diode is disposed outside the side light 303. The auxiliary light cover 304 and the lens cover 305 surrounding the 306 and the reflecting plate 307 are combined. Here, the reflector plate 307 reflects the light of the light emitting diode 306, and the lens cover 305 is a hemispherical or polyhedral shape (tetrahedron or trapezoid) capable of focusing and scattering light on the surface of a conventional optical lens (or polymer lens). At least one three-dimensional body having a hexahedron or the like is formed into the side assist lamp 303, thereby making it easier for pedestrians to observe the light. In the case of the lens cover 305, the green auxiliary signal light is installed green and the red auxiliary signal light red is installed. (The relative visual permeability of these colored lenses is referred to as `` traffic light manufacturing standard (Traffic Safety Management Corporation). Follow '). On the other hand, the power supply and the signal control of the side assistance lamp 303, like the main signal lamp 302, is supplied by the power supply in the enclosure and the signal lamp electronic module.

In Example 2, a perspective view 41, a front view 42, and a correlation measure 43 of the pedestrian traffic light 4 provided with the transmission prism in FIG. 4 were shown. As shown in FIG. 4, a right light passage 404 is formed on the right side of the traffic light shade 401 so that a right-turn driver (or pedestrian) can see the light color of the pedestrian traffic light. By attaching the transmission prism 406 having the same area to the signal light passage 404, the signal light is reflected directly from the main signal lamp 402 or on the lamp inner mirror 403 formed on the inner surface of the lampshade. The driver (or pedestrian) may turn right through the prism front surface 408 of the transmission prism 406 and through the prism rear surface 409. In addition, the front surface of the transmission prism 406 has at least one or more hemispherical or polyhedral light converging convex 407, which is transparent and has the same color as the color of the main traffic light 402 (this transmission prism The relative visual permeability of the colored state in (406) is in accordance with the Traffic Light Manufacturing Standard. In addition, the prism front surface 408 of the transmission prism 406 has a curvature to strengthen the focus of light, and the amount of light passing through the transmission prism 406 by forming a mirror on the inner surface of the traffic light shade 401 To increase. On the other hand, the transparent prism roof cover 405 that can block rain water on the upper portion of the prism prism 406 is also formed.

In the third embodiment, the shape of the traffic light shade 501 is asymmetrically as shown in the perspective view 51, the front view 52, and the correlation measure 53 of the pedestrian traffic light 5 provided with the reflective prism in FIG. Make. 5, the right turn (50-80% of the height) of the right side of the traffic light shade 501 is completely removed so that the right-turn driver (or pedestrian) can recognize the light color of the pedestrian traffic light. The reflective prism 506 is attached to the side opposite to the removed lower right side (reflection prism installation position 504), and is formed on the inner surface of the signal light and the lamp shade 501 which are directly incident from the main traffic light 502. The reflection prism 506 reflects the light reflected by the shaded mirror 503 again so that the driver (or pedestrian) may turn right. In addition, at least one hemispherical or polyhedral (light focusing) convex 507 is formed on the front surface of the reflective prism 506 to help focus and refraction of the reflected light, and the prism of the reflective prism 506 A mirror film was formed on the front surface 508 and the inner surface of the traffic light shade 501 to intensify the amount of light reflected after the main traffic light 502 light entered the reflective prism 506. In addition, in the traffic light shade 501, a reflective prism roof cover 505 that can prevent rainwater is formed on the reflective prism mounting position 504 where the reflective prism 506 is installed. On the other hand, in the third embodiment, since the reflective prism 506 directly reflects the light of the main signal, the right-turn driver or a pedestrian can easily recognize the signal change.

In the fourth embodiment, a slope 600 is formed on a normal pedestrian traffic light as shown in FIG. 6, and a flat puppet lamp (personal appearance of the main traffic light 302) is installed on the slope 600 or a three-dimensional traffic light (stop). (Red) doll lamp 621 and advanced (green) doll lamp 622). As shown in Fig. 6, in the perspective view 61 of the pedestrian traffic light 6 in which the doll lamp is installed on the slope, the center of the slope 600 is separated from the rear by a predetermined distance (the distance 604 between the doll lamp and the back of the lampshade). In the center of the slope, a human-shaped flat doll lamp or a three-dimensional doll lamp (a stationary (red) doll lamp 621, a progress (green) doll lamp 622) is installed. The flat puppet lamp may be made of only a light emitting diode like a normal pedestrian traffic light, but the three-dimensional doll lamp (stop (red) doll lamp 621, traveling (green) doll lamp 622) is made of polymer or glass. The stationary (red-green) doll lamp 621 is red and has at least one red light emitting diode 605 therein. The traveling (green) doll lamp 622 is green and has at least one green light emitting diode 605 therein. In addition, when viewed from the front of the pedestrian traffic light (6) having a doll lamp on the slope, the lamp left side 602 completely blocks the light, but the shade right side 603 is removed by a predetermined width to the right 610 Right turn drivers or pedestrians can quickly recognize the signal condition. On the other hand, since the corner angle of the slope 600 is 40 to 50 degrees, the length of the slope is 1.414 (± 10%) times one side of the square lampshade. Thus, the stationary (red) doll lamp 621 looks the same in both frontal, oblique or lateral directions, and in the case of the progressive (green) doll lamp 622, the oblique observation spreads laterally by 1.414 (± 10%) times. The frontal and side observations appear in their original form. For this reason, the width of the arms and legs is 1.414 (± 10%) wider when making the progress (green) doll lamp 622, making it easier to distinguish from the front and side viewing directions. Make accurate judgments.

In Example 5 shown in FIG. 7, the slope 700 is provided in the normal pedestrian traffic light, and (circle) or x display traffic lights are provided in this slope 700. As shown in FIG. As shown in Fig. 7, in the perspective view 71 of the pedestrian traffic light 7 provided with the 또는 or 표시 등 indicator, the center of the slope 700 is separated from the rear by a certain distance (the distance 704 between the traffic light and the rear face of the lamp). In the center of the slope 700, a ○ indicator 721 or a × indicator 722 is provided, and the ○ indicator 721 or a × indicator 722 is made of a light emitting diode 705. In addition, when the pedestrian traffic light 7 provided with the ○ or × indicator is seen from the front, the left side 702 of the lamp is completely blocked from the light, but the right side of the lamp 703 is removed by a predetermined width and the right direction 710. Make a right turn driver or pedestrian on the spot recognize the signal. On the other hand, since the corner angle of the slope 700 is 40 to 50 degrees, the length of the slope 700 is 1.414 (± 10%) times the one side of the square lampshade. Thus, when the ○ or × indicators 721 and 722 are observed in the oblique plane direction, they are spread sideways by 1.414 (± 10%) times, and the front and side observations appear as original. For this reason, when making the ○ indicator 721 or × indicator 722, make them long sideways (that is, ovals or sideways x long) so that the original ○ or × shape can be easily observed from the front and side viewing directions. By making it possible, people with red-green blindness can judge the signal state without confusion.
