Description

Automatic adaptive pedestrian crossing pedestrian traffic light {AUTOMATICALLY ADAPTIVE TRAFFIC SIGNAL LAMP FOR PEDESTRIAN CROSSING}

The present invention relates to a crosswalk pedestrian traffic light that controls the vehicle and at the same time to allow pedestrians to cross the crossing safely, more specifically, visibility at night by using a light emitting material as an LED and by configuring the light emission colors of day and night The present invention relates to a pedestrian crossing pedestrian traffic light to increase concentration and concentration.

In general, pedestrian traffic lights are installed at both sides of the crosswalk in order to induce safety of pedestrians waiting to cross the crosswalk separately from the vehicle control traffic lights controlling the vehicle.

Most pedestrian traffic lights are composed of a mark part shaped like a stationary person to inform the prohibition of crossing, a light source for emitting red light to the outside, and a pedestrian traffic signal to inform the pedestrian that it is traverseable. It is composed of a frame formed integrally with the shape of the mark portion and the lower portion composed of a light source for emitting green light to the outside.

In the conventional pedestrian traffic light, as shown in FIG. 1A, in order to represent red, green, or blue light sources used as marks for controlling crossing, an incandescent lamp is installed in a frame constituting an upper space and a lower space, respectively. And the human-shaped mark is produced in black to block the light of the incandescent light bulb, except that the base portion of the incandescent bulb alternately ON / OFF by using a color filter for indicating red and green or blue, respectively The identification was made possible.

However, the walking light using the incandescent light bulb as a light source uses a low efficiency incandescent light bulb, which consumes a lot of power and has a short life span of the light bulb, which requires at least every six months.

In addition, since the bulb has a characteristic of suddenly shutting down, planned maintenance is not possible, and there is a great social loss due to the concern of traffic safety accidents and disturbance of traffic flow, and it is introduced through the color filter under the strong summer sun. The light is reflected by the reflector of the incandescent bulb and radiated outside the signal signal, causing the possibility of a false traffic light, which may cause walking accidents.

Due to these problems, in recent years, LED signal lamps, which consist of semiconductor light emitting diode (LED) elements instead of incandescent lamps, have already been widely commercialized.

Since the LED device has its own advantages such as vivid and diverse colors, high brightness, low power consumption, and strong durability, the LED device overcomes the problems of the existing incandescent light bulb when used as a light source, improving visibility, saving energy, maintaining maintenance personnel, and There are many benefits, such as budget savings.

The general pedestrian traffic light using the LED element is composed of a red and green LED lamp only in the mark portion manufactured in the shape of a person as shown in Figure 1b so that the light is directly transmitted, separate from the base except the mark portion It is produced on a black background without a light source.

Therefore, when comparing the bar shown in FIG. 1A and FIG. 1B, the walking signal lamp of FIG. 1A having the incandescent light bulb as a light source is configured such that the base part except the human mark is emitted through the color filter to emit red or green light. The pedestrian traffic light of FIG. 1B is configured to identify whether or not a plurality of LEDs are directly emitted from the human-shaped mark portion and traverseable.

The existing pedestrian traffic lights do not have any problem in identifying the pedestrian signals during the day, but since the basic frame of the traffic lights is mostly made in black, the visibility of the traffic lights is reduced by the pedestrian or the driver, especially at night when the surroundings are difficult to identify. There is a limitation of configuration.

Accordingly, the present invention has been made in order to solve the above problems, and configured to distinguish the human-shaped mark portion and the base portion except the mark portion displayed on the traffic light into a separate space, the LED of the color corresponding to each space By installing a letter indicator on the side to recognize the walking signal status of the crosswalk in any direction without any deterioration of visibility at night, it provides a crosswalk walking signal that can always induce safety to the driver or pedestrian. The purpose is.

In order to achieve the above object, the automatic adaptive pedestrian crossing pedestrian traffic light according to the present invention has a human shape is configured such that the outer edge of the mark formed of a human shape in the traffic light body extends to the rear of the inside of the body to form a space The mark portion and the base portion forming the outside of the mark portion is configured to be separated, the mark LED is installed inside the mark portion, the base LED is installed on the base portion, the mark LED and the base LED has a different color It is configured to have, and during the day only one of the mark LED and the base LED is light-emitting, characterized in that it comprises a control box for controlling the mark LED and the base LED to emit light at the same time.

In the automatic adaptive pedestrian crossing pedestrian traffic light, only one LED of the mark LED and the base LED is emitted during the day and the mark LED and the base LED are emitted at the same time at the day, the side of the traffic light main body is a character indicator It is characterized by being further configured.

In the present invention, the human-shaped mark portion is formed in a separate space inside the main body of the traffic light, and in particular, the visibility and concentration are enhanced by simultaneously emitting two colors in contrast to the night when the concentration of pedestrians or drivers is reduced. The lighting condition of the traffic lights can be checked from the side, and the overall effect is to prevent pedestrian safety and traffic accidents occurring in crosswalks.

Hereinafter, the configuration and structure of the present invention will be described in detail with reference to the accompanying drawings.

2 to 4 show a schematic configuration diagram of a pedestrian crossing pedestrian traffic light produced according to the present invention, Figure 2 is a side view of the configuration to which the present invention is coupled, Figure 3 is a mark portion 110 according to the present invention 4 is a front view of the present invention, and is configured such that a human mark portion 110 and a plurality of LEDs 130 are installed into the main body 100.

The shape of the mark portion 110 shown in the figure is made in a form that prohibits crossing, but will be described below, the coupling relationship between the mark portion and the main body 100 is also the same as the shape of the person moving only the shape of the mark all different It is configured.

Existing general pedestrian traffic lights are formed so that the human-shaped mark portion that is displayed to recognize whether or not traversal can be formed only on the surface of the front portion, and the color or light emission can be identified by transmitting the light source installed inside the body to the outside.

However, in the present invention, the mark portion 110 is manufactured in a shape in which the human-shaped edge extends from the surface shape of the front portion to the rear of the main body 100, so that a separate space is formed inside the main body 100. .

That is, the inner space of the main body 100 is divided into a space formed by the mark portion 110 and a base portion 120 outside the mark portion partitioned by the outer edge of the mark portion 110.

Accordingly, the plurality of LEDs 130 installed in the main body 100 are divided into mark LEDs 131 installed in the mark unit 110 and base LEDs 132 installed in the base unit 120. The mark LED 131 and the base LED 132 are configured in different colors that contrast with each other to be easily identified when emitting light at the same time.

The front surface from which the light is emitted from the LED 130 is coupled to the main body 100 by installing a light transmitting portion 140, the light transmitting portion 140 includes a constant strength so as not to be easily damaged by the impact due to external pressure The light emitted from the LED 130 is preferably made of tempered glass or polycarbonate (PC) so that the light is easily refracted without being refracted.

Through the present invention configured as described above, it is easy to identify the surroundings and traffic lights during the day to operate only one LED of the mark LED 131 or the base LED 132 like the existing traffic lights so as to recognize whether the pedestrian is crossing. In addition, at night when it is difficult to identify a traffic light and surroundings, the mark LED 131 and the base LED 132 emit light at the same time to enhance visibility and concentration so that vehicle drivers and pedestrians can always induce safe driving and walking. To help.

In general, the selection of the color emitted from the LED is composed of a red LED symbolizing warning and danger and a green LED symbolizing safety to express the possibility of walking, and effectively contrast the red and green and visibility at night White LEDs are used to secure more emphasis.

In addition, in the present invention, as shown in FIG. 2, a plurality of LEDs 130 installed inside the main body 100 are configured to be installed at the bottom of the inside.

This means that when the LED 130 is located on the surface of the traffic light transmitting unit 140 and emits light, the light transmitted from the boundary between the base unit 120 and the mark unit 110 adjacent to the base unit 120 is transmitted. The purpose is to prevent color bleeding from mixing with each other and cause eye fatigue.

That is, in the configuration of the existing traffic light, the light source is installed adjacent to the light emitting part of the front of the traffic light so that strong sunlight is introduced into the light transmitting part to block the spread of light reflected or emitted from the light source. A sun visor was formed.

However, in the present invention, since the LED 130 is configured to emit light from the base portion 120 and the bottom portion of the mark portion 110, which are partitioned into separate spaces, the light source having two colors of light emitted from the adjacent boundary. By blocking the color bleeding phenomenon to be mixed, it is not necessary to install the shade plate, such as a conventional traffic light, it can be said to be a preferred configuration to increase the visibility and reduce the manufacturing cost.

The method of the LED 130 is installed inside the main body 100 and the electrical coupling and power installed for the operation is the same as the existing walking signal light and sufficient description can be implemented because of already known techniques Omit it.

5 to 6 show the state of the light source operated during the day and night and the identification effect according to the present invention produced according to the embodiment compared to the conventional traffic lights.

First, Figure 5 compares the configuration of the present invention with a general walking signal light, the main body of the traffic light divided into the upper and lower, the base portion 120 of each traffic light, the red and green background LED 132 is installed During the day, the background LED 132 alternately emits light to configure whether or not to cross.

At this time, a mark LED 131 emitting white light is installed inside the mark unit 110, but it is not necessary to light up to the mark LED 131 because only enough lighting of the background LED 132 is possible during the day.

However, at night when it is difficult to identify the surroundings and the location of the traffic light, the mark LED 131 which emits white light is alternately lit along the background LED 132 which alternately lights to recognize whether the crosswalk can be walked at the upper and lower parts of the traffic light frame. It is configured to emit light at the same time.

Accordingly, as shown in the drawing, the white mark LED 131 is turned on at the same time as the background LED 132 which emits red and green light at night, compared to the conventional general pedestrian traffic light using an incandescent bulb, so that visibility and concentration are increased. You can get more effective.

FIG. 6 compares the present invention with a conventional LED walking signal lamp in which red and green LEDs are respectively installed along a human shape, and in the present invention, a background LED emitting white light on a base 120 formed as a separate space. 132 is installed.

In the embodiment of the present invention installed as described above, in the daytime, as in the conventional LED walking signal light, only the red and green mark LEDs 131 are configured to operate alternately, and in the case of the night background LED 132 of white. It is configured to simultaneously emit light along the red and green mark LED 131, it can be seen that the configuration to have a much higher visibility and concentration compared to the general LED walking signal light even in the night as shown .

FIG. 7 is a schematic diagram illustrating a practical configuration of a walking signal lamp manufactured according to the present invention. A remaining time indicator 150 displaying a traversable time is provided below the crosswalk walking signal lamp installed in the form of a column. In addition to the side portion of the main body is further configured character indicator 160.

The character indicator 160 installs a character LED in which red and green light sources alternately emit light to determine whether the pedestrian crossing can be traversed, so that the pedestrian or vehicle driver may recognize the traversable state in advance regardless of the moving direction. It plays a role.

In particular, as shown in the "crosswalk" directly present the letter to emit light for 24 hours, when displayed in color only to block the risk of misjudgment to the driver of the vehicle as a traffic control signal and for safety accidents of crosswalks The effect of recognizing the alert in advance can be obtained.

In addition, the traffic light automatically recognizes the sunset and sunrise time, or if the day and night time zones are set arbitrarily, the control box is configured to control the mark LED and the background LED installed inside the main body to be selectively or simultaneously emitted and repaired automatically. And maintenance can be facilitated.
