Description

Stallable traffic light and its implementation method {The practical traffic light and its fabrication method}

The present invention relates to more stalled traffic lights than conventional pedestrian and driver traffic lights. Typical driver signals consist of red (stop), yellow (caution), green (straight), and green arrows (left turn), and for pedestrian signals, red (stop), green (cross) and time-lapse It consists of a timer signal (scale or number).

Currently, in the case of the widely used traffic lights, each component traffic light is displayed in a single color, and only one function is implemented in one traffic light (recently the idea of the traffic light as the LED light is rapidly spreading (circular, 1). There is no reason to insist on function 1 traffic lights), but it has not yet escaped from the original idea.

For reference, the built-in multicolor LED has three or more terminals. Normally, LEDs have a long lifespan (more than 50 times that of a light bulb), low power consumption (more than 80% savings), and low maintenance costs. It has good visibility against backlight, and there is no condition that the whole traffic light goes out even if some LEDs fail. As a result, even if the initial investment cost is large, the entire traffic light is rapidly changing to LED, especially in the US and Europe.

A normal traffic light is composed of a driver and a pedestrian. The driver traffic light has a circular (red) stop (11), a yellow (caution) (12) signal and a green (straight) (14) and an 'arrow' shape. It consists of a green (left turn) 13 signal (Figure 1a), and a pedestrian traffic light is a red (stop) 21 in the shape of a standing person, a green (across) 22 in the shape of a walking person and time-lapse Is composed of a timer signal 23 ('scale' 231 or 'number' 232) indicating (FIG. 1B).

The existing traffic lights shown in FIGS. 1a and 1b have the following weaknesses and improvements. Color blinders (especially red-green blindness) can't distinguish between stop and go signs of driver lights. In the event of a traffic accident, if the only witness is red-green blindness when trying to pass the responsibility to each other, the driver may not be judged to comply with the signal regulations, and may be inadequately punished.

In addition, in the case of a normal traffic light, the total area of each component traffic light (green, yellow, red) is displayed in a single color (driver's traffic light), and only one signal function is implemented in one traffic light (driver's and pedestrian traffic lights). If several signal functions are integrated into one signal lamp, it is necessary to reduce power consumption and production cost.

The followings are the disadvantages of the existing traffic lights and the suggestions for improvement.

First, those who are red-green blind cannot distinguish between stop and progress signals, and therefore cannot obtain a driver's license. Laws that should be equal to all have led to inequalities that openly grieve the red-green underprivileged due to the regulations on traffic signal marking. Therefore, it is necessary to redefine the red-green weak so that they can distinguish the stop and progress signals.

In addition, it is necessary to unify the signal shapes of the driver signal and the pedestrian signal. That is, in the case of the green signal shape indicating progress (crossing), the driver signal is circular while the pedestrian signal is a walking person, and the red signal indicating stop is also circular, while the driver signal is circular, while the pedestrian signal is a person standing. It is appearance. Therefore, it is necessary to unify this, but consider the color weakness, change the difference (go or stop) between the two signals to a clear shape, and establish a 'standard for the traffic signal display system of the world' based on this.

Second, in the case of a conventional traffic light, only one signal function is included in one traffic light, and a red, green, or yellow light emitting diode is installed in the entire area of the circular traffic light, thus operating at low efficiency compared to high production cost. Therefore, in the current system, which is one signal and one signal lamp, by integrating two or three signal functions into one signal lamp, a method of reducing power consumption or production cost is found.

Third, in the case of a pedestrian traffic light, the opposite signal can be observed well from the side of the pedestrian, but the side (the side of the pedestrian) cannot cover the signal shade. The same is true for drivers who turn right, which is why pedestrians and drivers who turn right cannot currently determine the crossing status of pedestrians. Obscured). Therefore, while making it visible from the side, the first and second improvement measures are applied to find a solution.

The solution for each problem to be solved by the present invention is presented in the methodological position as follows. The solution to the first task is as follows.

[1] Red-green color blind persons should be able to distinguish between stop and progress signals, but not to deviate significantly from their current shape, thereby minimizing people's adaptation time. In this way, the current 'color signal display', which depends only on color, is changed to the 'symbol-color' signal display system (the symbol adopts ◎, ×, which is most familiar to people in the world). That is, as shown in Fig. 2A, the stop is red-X 110, the advancing (cross) is green-X-140 140, and the attention and left turn signals are left as they are. With only minor modifications, the red-green color can be distinguished and people can quickly adapt to the changed traffic signal.

[2] In the case of a pedestrian signal, the stop sign is a 'stander' shape 21 and the cross mark is a 'walker' shape 22 (FIG. 1b). This is not an easy to distinguish labeling method for the red-green underprivileged. Therefore, it is also clear to the color weak and, for consistency of the signal display, the shape of the 'driver's signal' and the 'pedestrian signal' are unified, but the progress or stop indication is determined according to the solution [1]. That is, as shown in FIG. 3a, the stop changes to 'red-x table 401', the progress (crossing) to 'green- ◎ table 402', and the timer function may use the existing method, but the green ◎ In the table 402, the inner circle (i.e., ◎) is decremented in a clockwise direction. (If there is a better indication, of course, you can adopt it, but if you are aiming for a 'world standard,' Simple symbols are preferred.).

The solution to the second task is as follows.

[3] The current traffic light is a '1 signal 1 traffic light' display system in which one signal light has one signal mark (FIGS. 1A and 1B). In addition, in the case of a driver's signal lamp, the same monochromatic (R, G, Orange) LEDs are installed on the entire area of the circle to operate with high production cost and low efficiency. Therefore, as shown in FIG. 3, in principle, the current system (one signal, one signal lamp) is designed by integrating two or three signal functions into one signal lamp, thereby greatly reducing power and production costs, Uniquely designed and used multi-color LED and signal light cover (lens). Details are given in the Implementation of the Invention section.

The solution to the third task is as follows.

[4] In the case of a normal pedestrian traffic light, if a large vehicle obstructs the traffic light on the opposite side, a pedestrian heading toward a crosswalk can determine whether or not he or she must run to cross by looking at the traffic light on his side. However, the signal light is hidden by the signal shade and cannot be seen from the side. This is the same for 'turning right drivers', which is why a 'turning right driver' approaching a crosswalk is often unable to determine the crossing status of a pedestrian, which often results in safety accidents. For this purpose, the present inventor has already filed a pedestrian traffic light with an auxiliary signal so that it can be seen from the side (Patent Application No. 10-2008-0097912). It is an object to present an embodiment, and for that purpose, the signal display between the main signal and the auxiliary signal of a driver signal, a pedestrian signal, and the like is unified.

Advantages of the present invention are as follows.

First, in order to be able to distinguish between progress (green) and stop (red) signals, those who are red-green blind, the current 'color signal display method' is a symbol-color combined signal display method (stop: red- × display, progress) (Traverse): green-◎), and the rest (caution: yellow, left turn: green arrow) is left unchanged from the current shape, such as the current state (Figures 2 to 4), people's signal display changes Reduced adaptation time to

Second, as shown in the first effect above, by unifying the shape of 'driver's signal' and 'pedestrian's signal', the signal display was kept consistent, and from this, it was possible to clearly establish driving rights of color weak people. Reaffirm that you are equal before you.

Third, the widely used traffic light is a '1 signal 1 traffic light' display system (Fig. 1a and 1b). In the case of driver's traffic light, the same monochromatic LED is installed on the entire surface of the circle to operate with high efficiency and low efficiency. However, the present invention makes the most of the advantages of LED, and in the present method (1 signal 1 signal lamp), by integrating two or three signal functions into one signal lamp (Figure 3), it is possible to drastically reduce power consumption and production cost. .

Fourth, it is not installed in a normal pedestrian traffic light, but the 'aid signal light' ('the driver who turns right') mentioned in the unpublished patent application filed by the present inventor can not determine whether the pedestrian is currently crossing or not. Invented as a means of reducing accidents.) By applying this idea (unification of signal display between driver traffic light, pedestrian traffic light and pedestrian traffic light), 'consistency of traffic signal display' can be extended to all 'traffic light'.

Furthermore, based on the above-mentioned advantages, Korea has established an opportunity to establish the 'standard for the display of world traffic signals'.

The present invention relates to pedestrian and driver traffic lights, and is presented for the purpose of realizing and realizing more traffic lights through energy saving, color weakness consideration, and production cost reduction. In other words, unlike the existing traffic lights, by adopting the 'symbol-color combined display' method, instead of the 'color signal display' method of displaying the entire area of the signal only in a single color (red, green), it is absolutely useful to the red-green weak people. In addition, by integrating two to three signal functions into one signal lamp, it is an object of the present invention to significantly reduce the power consumption and production cost.

When explaining the configuration and features versus features (first to third) with respect to the specific content for the practice of the present invention.

First, in [1] and [2] of the above-mentioned problem solving means, a new 'signal-color signal display' method is applied so that the red-green weak people can be clearly distinguished, but the public can quickly adapt the new signal display. The driver's signal adopts progress (green ◎ mark, present invention), stop (red × mark, present invention), left turn (green ← mark, as it is), attention (yellow round mark, as it is), and pedestrian signal. In time-lapse adopts donut timer indication. These are shown in FIGS. 2a (driver's signal) and 3a (pedestrian signal).

First, embodiment (1) of the present invention (symbol-color combined display) for implementing a driver signal (Fig. 2a) is as follows. The stop and progress signals represented by the existing circles are replaced by the X and Equations 110 and 140, respectively. It is installed at a predetermined density (eg, more than the existing density), and the outside does not install LED at all. The remainder (the 'attention' (12) and the 'turn left' (13) signals are left as is. If only a slight change is needed, the red and green weak people can be distinguished, and the public can adapt quickly, and by installing LED only in the × (110) and ◎ table 140, it can save electricity. In embodiment (1) of the present invention, the size of the traffic light is made the same or slightly larger (100-110%) than the existing one.

In the case of a pedestrian signal, the 'stop' sign is a 'stander' shape 21 and the cross mark is a 'walker' shape 22 (Fig. 1b). This is difficult to distinguish among color weak people who have difficulty distinguishing red rust color. Therefore, it is clear to the color weak and, for consistency of the signal display, the shape of the "pedestrian signal" is also the same as the "driver signal" (Example (1) of the present invention). That is, as shown in FIG. 3a, the stop is changed to 'red-x table 401', the progress (crossing) is changed to 'green- ◎ table 402', and the timer function is a conventional method (scale 221 or number). (222)) may be used.

Second, in [3] of the 'problem solving means', the 'multi-signal 1 traffic light (2 to 3 signals)' is removed from the '1 signal 1 traffic light' display system (FIGS. 1a and 1b) applied to a normal traffic light. The integrated signal display is shown in FIGS. 2a to 2c and 3a to 3c under the principle of designing the function in a single signal lamp). That is, in the case of a driver's traffic light, the green ← (left turn) and the yellow-circular (caution) signs are integrated into another traffic light 200, and the 'green- ◎' and 'red-x' stop signs' Is integrated into one traffic light 400 (Fig. 2a).

Embodiment (2) of the present invention is implemented by integrating two signals into one signal lamp (i.e., reducing the four traffic lights into two by integrating the x and ◎ tables and the ← and 'caution' tables). 2a and 2b). Embodiment (2) of this invention is as follows. First, as shown in FIG. 2b, the integrated traffic light 200 of the ← and 'attention' table and the traffic light 400 with the x and ◎ table are designed (here, the reason for not integrating the ← and ◎ table is' Because it can't express the simultaneous signal of 'left'. At this time, the size and thickness of the symbol and the LED placement density are set to predetermined values optimized to maximize the effect of each function.

For example, the thickness of the × (110) and ◎ table 140 of the present invention is set to four to six LEDs (101 to 106) on the basis of the existing LED batch density, ← table 130 is a conventional Install with 3-5 LEDs (101,102) based on LED placement density. In addition, the method of determining the size (and width) of them (Fig. 2c) is to make the traffic light of the present invention about 15 to 20% wider than the conventional one (11 to 14), but in a square frame (200, 400), In the square frame, the x table 110 is formed up to each corner vertex 410 of the square, the table 140 is designed to be close to the inscribed circle (230,430) of the four sides 220,420 of the square frame to a predetermined distance. In addition, ← table 130 is formed inside the 'caution' display circumference 120 formed in the inscribed circle 230 of the four sides of the square frame 220 is made about 15 to 20% wider than the existing one (13).

On the other hand, the arrangement and installation of the LED for implementing the embodiment (1, 2) of the present invention can be installed in two ways as follows.

If one uses a single color (red, green, amber) LED, the ← table 130 is green, but the 'caution' sign (12) is yellow (101) on the front, so the ← mark (130) on the LED installation board After all of the green LEDs 102 have been installed, the appropriate predetermined locations 101 within them are selected, and the yellow LEDs 101 are replaced and installed instead of the green LEDs 102. Then, the substrate is covered with a glass cover 300, in which a convex 700 having a predetermined shape is formed at a position 350 corresponding to the signal of the arrow 130. The LED light emitted toward the convex 700 passes straight through the tooth 700 and then goes straight (refraction 2c). According to the yellow 'caution' or green 'turn left' signal cycle, only the green LED or only the yellow LED is turned on. When the 'turn left' signal, the green ← mark 130 is turned on. Indication 130 is turned off and all yellow LEDs 101 in the circle, including the yellow LEDs 101 therein, are turned on. The convex 700 serves to fill the empty space of the turned off green LED position with (yellow) light reflection and refraction. The reverse process, ← (130) ⇒ 'caution' (120), is explained in the same logic.

In the same manner as above, the integrated signal lamp 400 of the X and Y marks is also formed (FIG. 2B). As shown in FIG. 2C, the red LED 103 is provided in the X table 110 of the substrate, the green LED 101 is provided in the Y table 140, and the intersection region 150 of the X and Y table is provided. Install the red and green LEDs alternately. Then, the substrate is covered with a glass cover 500, which has a predetermined shape of convex 700 at a position 350 corresponding to the intersection 150. The LED light emitted toward the convex 700 passes straight through the tooth 700 and then goes straight (refraction 2c). Depending on the cycle of the red 'stop' or green 'go' signal, only the red LED 103 is turned on or only the green LED 101 is turned on. When the 'go' signal is turned on, the green ◎ table 140 is turned on, and this is the 'stop'. When the signal is switched, the green LED 101 in the cross section 150 and the cross section 150 are turned off, and the red LED 103 of all X marks including the red LED 103 in the cross section 150 are turned on. . The convex 700 serves to fill the empty space at the position of the green LED 101 turned off in the cross region 150 with red light through reflection and refraction. The reverse process is the same logic. In addition, the LED 100 having a larger light emitting capacity may be used in the cross region.

Another method is to install the dual-color LEDs 104 and 106 from the beginning in the color common part (← 130 in the 'attention' 120), and in the intersection area 150 between the × (110) and the ◎ table 140. (Fig. 2c) Nowadays, a light emitting diode that emits a few colors is produced by one device, and thus two or three signal functions can be integrated into one signal lamp (e.g., gallium phosphide (GaP): red, yellow, Green light emission, aluminum / indium / gallium / phosphorus (AlGaInP): yellow, yellow, green light emission, i.e., a dual color LED 104 for selectively emitting yellow and green light is indicated by the ← mark 130; In the table intersection portion 150, a dual color LED 106 that selectively emits red and green light is installed, and the dual color LEDs 104 and 106 installed in the common portion 130 and 150 are 'attention' according to the signal period. In this case, yellow light is emitted, green light is emitted when 'left turn', red light is emitted when 'stop', and green light is emitted when 'progress'. In parallel with the cross-area it can be used for the electrically luminescence capacity larger LED (100).

On the other hand, in the case of pedestrian traffic light, according to the 'implementation (plan)' of the present invention in FIG. 3a, the 'timer' function (1 to 8) is integrated into the 'going (crossing)' signal (green- ◎ (402)). An embodiment (3) of the implemented traffic light 403 is shown in FIG. 3B (600). In the 'timer' function, the inner circle (inner part of ◎) is divided into eight equal parts in a clockwise direction from the 1/8 quadrant (1) while only the outermost circle is turned on at the crossing (green- ◎) 402. Reduce by an area (1/8 quadrant), near the end of the transit time (e.g. after 20 seconds), 8/8 quadrant (8) turns off (a few seconds later) and the outermost circle (9) also turns off and stops soon ( Designed to be converted to a red-x) signal. As shown in Fig. 3a, the process of changing from the green-? Signal to the red-x is in the order of 402? 403 (cross)?

Furthermore, in the pedestrian traffic light, the embodiment of FIG. 3A integrating three functions, 'green- ◎' 402, 'timers' 1-8 and red- × 401, into one traffic light 800 It is shown in (4), and the specific design drawing is shown in FIG. 3B (800). Also in this embodiment (4), the process of changing from the green- ◎ signal to the red-X is the same as in the above embodiment (3), but the 'green- ◎' 402 and the 'timers' (1-8) and red- The difference is that the three signal functions, such as × (401) is integrated into one signal lamp, which has the advantage that the production cost can be further reduced than the embodiment (3).

The arrangement and installation of LEDs for implementing embodiments (3, 4) of the present invention can be installed in two ways as follows.

According to the schematic 600 of the embodiment (3) of FIG. 3b, two traffic lights 401 and 403 are made, one traffic light 401 comprising a stop signal (red-x), and the other a crossing signal (green). -◎) and timer (8 quarter donut scale). Table 110 is provided with a red LED 103, ◎ Table 140 is installed a green LED 101, the 'timer' function is the crossing (green- ◎) 402 the outermost circle ( Thickness: In the state that only one green LED is turned on, the inside area (inside part of ◎, thickness: three or five green LEDs) divided into eight equal parts clockwise from 1/8 quadrant (1) to a predetermined area (1 / 8 quadrant), near the end of the transit time (e.g. after 20 seconds), the 8/8 quadrant (8) turns off (after 2 seconds) and the outermost circle (9) also turns off (red-x). The electronic timing function is applied to convert the signal.

If the embodiment 4 of FIG. 3B is implemented according to the corresponding design diagram ('800' of FIG. 3C), there are two methods as follows.

First, the red LED 103 is installed in the X table 110 of the substrate, the green LED 101 is installed in the ◎ table 140, and the red and green LEDs are alternately arranged in the cross region 150 of the X and ◎ tables. Install. Then, the substrate is covered with a glass cover 500, which has a predetermined shape of convex 700 at a position 350 corresponding to the intersection 150. The LED light emitted toward the convex 700 passes through the tooth 700 and then passes through the refractive index and then goes straight (FIG. 3C). Depending on the cycle of the red 'stop' or green 'go' signal, only the red LED 103 is turned on or only the green LED 101 is turned on.In the 'go' signal, the green ◎ table 140 turns on, and after 2 seconds ( Assuming a crossing time of 20 seconds), while the 'timer' function is operated and only the outermost circle (thickness: 1 green LED) is turned on at the crossing (green- ◎) 402, the internal source (thickness: green LED) is turned on. 3 to 5) divided into 8 equal parts clockwise from 1/8 quadrant (1) to a predetermined area (1/8 quadrant), and at the end of the crossing time (e.g. after 20 seconds), 8 After the / 8 quadrant 8 is turned off (after 2 seconds), the outermost circle 9 is also turned off and soon switches to the stop (red-x) signal. When it is switched to the 'stop' signal, the green LED 101 in the table 140 and the intersection area 150 is turned off, and the red LED 103 of all X tables including the red LED 103 in the intersection area 150 is turned off. It turns on. The convex 700 of the glass cover 500 serves to fill the empty space at the position of the green LED 101 turned off in the intersection area 150 with red light through reflection and refraction. The reverse process is the same logic. In addition, the LED 100 having a larger light emitting capacity may be used in the cross region.

The other method is to install the dual-color LED 106 from the beginning in the color common part (← 130 in the 'attention' 120) and the intersection area 150 between the × (110) and the ◎ table 140. (Fig. 3c) That is, a double-colored LED 106 that selectively emits red and green light is installed at the cross section 150 of the X and ◎ marks, and then the double installed in the common part 150 according to the signal period. When the color LED 106 is 'stop', it emits red, and when it is 'progress', it emits green, and in parallel, the LED 100 having a larger light emission amount may be used in a common area. .

Third, the task solution means, that is, the pedestrian traffic light (900 and 1000), such as 4a and 4b, so that the 'pedestrian' or 'turning right' approaching the crosswalk can determine the current crossing status of pedestrians. By forming the auxiliary signal lamps 910, 920 and 1100 on the right side of the main signals 600 and 800, the three-signal two-signal 900 or the three-signal one-signal 1000 can be implemented. In the case of the three-signal two-traffic light 900 (FIG. 4A), auxiliary signal lights 910 (403, 920 (401)) are formed on the right side of the main signal 600 (403, 401) of the pedestrian traffic light 900, and 3 In the case of the signal 1 traffic light 1000 (FIG. 4B), the auxiliary signal light 1100 is formed on the right side of the main signal 800 of the pedestrian traffic light 1000, but the main signals 600 and 800 and the auxiliary signal ( The signal display and signal switching period between the 910,920 and 1100 are unified. This is because the driver who wants to turn right must recognize the signal change from the pedestrian's point of view, not from the driver's point of view. In addition, the side observation auxiliary light is made smaller than the size of the main signal.
