Description

Floor traffic lights interlocked with pedestrian traffic lights

The present invention relates to a floor traffic light interlocked with a pedestrian traffic light, and to a floor traffic light displaying a signal using light emission from the floor surface of the edge of a crosswalk. It is a device that signals to cross safely. It is usually installed on both poles of a crosswalk. It uses green and red signals, which are walking signals, so that pedestrians can cross the road or wait.

In other words, pedestrians cross the crosswalk by checking the pedestrian traffic lights installed on the opposite pillars outside the safety line adjacent to the crosswalk. It is inconvenient to see the pedestrian traffic light on the opposite side when stopping nearby, and it is inconvenient because the pedestrian traffic light on the opposite side cannot be checked when pedestrians are using a smartphone while waiting for a signal.

In order to solve this problem, looking at the Republic of Korea Public Utility Model Publication No. 20-2013-0005542, a pedestrian traffic light is installed through the luminous sidewalk block installed on the floor for pedestrians who want to cross the crosswalk by installing a sidewalk block that is lit in conjunction with the pedestrian traffic light in the crosswalk. It is possible to check whether this signal is a green signal or a red signal.

However, the light-emitting sidewalk block of the Open Utility Model Publication No. 20-2013-0005542 technology operates only with the red signal, which is a walking stop signal, and the green signal, which is a walking signal. There is a problem that it is not possible to check whether is red or green.

Color blindness or color blindness is classified into total color blindness, partial color blindness, color blindness, etc., depending on the symptoms, and can be divided into primary color vision abnormality, secondary color vision abnormality, and third color vision abnormality depending on the type of color that cannot be distinguished.

Partial color blindness is the most common case of color blindness and is caused by a lack of cone cells that recognize the three primary colors of red, green, and blue in the retina. In the second color vision abnormality, there is no M cone cell that recognizes green, and like the first color vision abnormality, red and green cannot be distinguished. However, unlike the first color vision abnormality, green is distinguished as dark do.

Most of the color blind people have red and green blindness caused by a first or second color blindness, so they have a problem in that they cannot distinguish the red and green signs of the traffic lights emitting from the floor of the crosswalk.

Looking at Republic of Korea Patent No. 10-0679852, although it is not for the purpose of color blind people, if you look at paragraph [0016], "If you look at an example in which the signal display block 1 is operated in connection with the pedestrian traffic light 100, pedestrians A lighting device that emits red light and a lighting device that emits green light, such as the traffic light 100 for a signal, are installed in one signal display block at the same time to be selectively turned on, or a signal display having a lighting device that emits red light It may be possible to install a block for signal display and a block for signal display with a lighting device that emits green light at the same time so that they operate sequentially.”

Looking at the contents of paragraph [0016] of Korean Patent Registration No. 10-0679852, this also installs a block that emits a red signal and a block that emits a green signal. If it is a red signal, a red block is emitted, so there is a problem that the color blind cannot distinguish the green signal from the red signal.

In addition, looking at the contents of paragraph [0017] of Korean Patent Registration No. 10-0679852, "or a green cover plate 30 is installed on some signal display blocks 1, and some signal display blocks 1 have a red color. It is also possible to install the colored cover plate 30 and light it alternately like a pedestrian traffic light . . . . . Since the red cover plate emits a red signal, there is a problem that the color blind cannot distinguish the green signal from the red signal.

In addition, referring to paragraphs [0017] and [Fig. 1] of Korean Patent Registration No. 10-0679852, " . . . . . . . . . . ) may be displayed.", and looking at paragraph [0022], it is indicated that "... it is done

Looking at paragraph [0017] and paragraph [0022] and [Fig. 1], a picture indicating a crossing/stop is displayed so that a picture of the display panel 20 is displayed when it is turned on.

However, when the arrows and X marks displayed on the luminescent sidewalk block of Patent Registration No. 10-0679852 are displayed on a block of 30cmX30cm size, the block is large and thus a figure such as an arrow and an X mark can be formed. If the block is made large, another number of problems arise.

In other words, since the floor traffic light is installed in the ground, it must be completely waterproofed. However, if the width of the floor traffic light is widened, it is difficult to perform a perfect waterproof treatment because the overall width is wide.

In addition, if the floor traffic light is made wide and large, manufacturing costs such as case and LED PCB increase, and when installed nationwide, there is a problem of excessive electricity bills, and there is a problem that it is not simple for pedestrians.

If the width of the floor traffic light installed at the site is widened, there is a problem as described above, so looking at the National Police Agency standard guidelines to solve this problem, the width is designated as 10cm. The part of the LED that displays the is only 7cm.

If an attempt is made to display a picture such as arrows and X marks on a width of 7cm, the picture cannot be displayed due to the narrow width. Of course, there is a problem that it is not easy for the color-blind person to identify and distinguish the picture.

Despite the suggestion that color blind people should be able to distinguish between green and red signals while many floor traffic lights are being installed at the site, the LED width of the floor traffic lights is narrow (7 cm), so no pictures are displayed on the floor traffic lights. If the pedestrian traffic light is green, the entire floor traffic light is also displayed in green, and if the pedestrian traffic light is red, the entire floor traffic light is also displayed in red. The problem of not being able to distinguish between green and red markings through floor traffic lights continues.

In addition, referring to paragraphs [0011], paragraphs [0012] and [Fig. 2] of Korean Patent Publication No. 10-0679852, the LED 12 is installed on the side and the indirect light emitted from the side is illuminated on the top of the sidewalk block. By seating the display panel 20 expressed by means such as printing or perforation, the light emitted from the LED 12 on the side is displayed through the printed display panel 20. Because it is lighting, there is a problem that it is difficult to see well in direct sunlight during the day.

Therefore, as in the prior art, the problem cannot be solved by a method of emitting a specific shape by seating a sign expressed by means such as printing or perforation.

In addition, Patent Registration No. 10-0679852 does not provide an alternative to solve the above problems, so even when the width of the signal display part of the floor traffic light is only 7 cm, the color-blind person can easily distinguish the green signal from the red signal. There is a need for alternatives and alternatives that allow color blind people to clearly distinguish between green and red signals even during the day.

The floor traffic light interlocked with the pedestrian traffic light according to an embodiment of the present invention solves the problems of the floor traffic light installed on the floor used in the prior art, and provides a floor traffic light of a new concept different from the conventional floor traffic light. do it with

Even when the signal display area of the floor traffic light is only 7cm wide, the color blind can easily distinguish the red signal from the green signal. It is a task to be able to clearly distinguish whether it is a green signal or a red signal.

green signals

52 and 25 as shown in FIG. 7, the signal display of the floor traffic light 10 is also expressed as the green signal display 25, As shown in 8, when the pedestrian traffic light 50 is changed to the

red signals

51 and 26, the entire signal display of the floor traffic light 10 is also changed to the red signal display 26, and when the pedestrian traffic light 50 is green flashing, the floor The traffic light 10 is also changed to a green flashing signal.

The floor traffic lights as described above are easily used by ordinary people who want to cross the crosswalk. Color blind people have a problem in that they cannot distinguish a red signal display from a green signal display.

The floor traffic light 10 being installed in the field is installed by limiting the width of the signal display unit 20, which is an LED of the floor traffic light, to 7 cm in consideration of aesthetics, efficiency, and economy.

In order for the color-blind person to distinguish the green and red markings of the floor traffic light 10, an arrow, etc., should be expressed on the signal display unit 20 of the floor traffic light 10 so that they can be distinguished. In the signal display unit 20, which is an LED of 10), the width is too narrow to express any picture.

Despite the fact that many floor traffic lights are installed in the field because this problem cannot be solved, the floor traffic lights currently being installed, if the pedestrian traffic light 50 is a green signal, the floor traffic light 10 is simply displayed in green, and the pedestrian traffic light ( If 50) is a red signal, the floor traffic light 10 is also simply displayed in red, so there is a problem in that it is not possible to determine whether the color blind person is a green signal or a red signal.

There is an urgent need for an alternative that can determine whether the color blind person is a green signal or a red signal even when the width of the signal display unit 20 of the LED floor traffic light installed in the field is 7 cm.

In order to solve this problem, referring to FIG. 6, unlike FIG. 5, the LED light emitting unit 24 arranged in the signal display unit 20 is divided into a first signal display group 21 and a second signal display group 22, and a pedestrian traffic light When 50 is a green signal, power is supplied to the LED light emitting unit 24 that is the first signal display group 21 so that only the LED light emitting unit 24 of the first signal display group 21 emits light, and the second The LED light-emitting unit 24, which is the signal display group 22, is powered off so that the LED light-emitting unit 24, which is the second signal display group 22, does not emit light, and spaced one by one as shown in FIGS. 6 and 7 ( 23) Make the green signal display 25 be displayed, and when the pedestrian traffic light 50 changes to a red signal, both the first signal display group 21 and the second signal display group 22 are displayed in red as shown in FIG. did.

When the signal of the pedestrian traffic light 50 is a green signal, it can be formed by densely floating the second signal display group 22 as shown in FIG. Similarly, the second signal display group 22 may be widely floated (23) and the first signal display group 21 in the shape of a green rectangle may be widely arranged.

In the present invention, instead of forming any picture on the signal display unit 20, which is the LED of the floor traffic light, the signal display unit 20 is spaced closely at regular intervals to display green with a green signal, and red for the red signal without floating. Even if it is only 7cm, it has the effect of being clearly and clearly expressed.

In addition, in some cases, in the present invention, the first signal display group 21 may be expressed in various shapes such as a triangular shape instead of a rectangular shape as shown in FIG. 7 .

In addition, in some cases, it will be possible to float more densely than in Fig. 9B. In the present invention, the expression that the first display group 21 is displayed and the second display group 22 is not displayed means that the floor traffic light is green. In order to distinguish between the first display group 21 and the second display group 22 that are not displayed, the first display group 21 and the second display group 22 are for the purpose of distinguishing the display group 21 from the second display group 22 that are not displayed. Either one of the two display groups is powered off so that no signal is displayed, or one of the two display groups is displayed in a different color while supplying electricity, or one of the two display groups has a different shape In the case of displaying as , "thing not to be displayed", "to be displayed in a different color", and "to be displayed in a different shape" will all fall under "not displayed" as described in the present invention. .

In the present invention, the space between the first signal display group 21 or the second signal display group 22 and the signal display color, etc. can be formed in various ways so that the color-blind person can efficiently use the floor traffic light. will be.
