Description

Traffic light {TRAFFIC SIGNAL LAMP}

The present invention consists of a number of inverted triangles each using a red and green LED in the vertical direction, and then turns on the green LED in the pedestrian progress signal to make the pedestrian proceed, and before the pedestrian progress signal changes to the vehicle progress signal, The green inverted triangles are turned off one by one, indicating the time when the vehicle progress signal is changed. On the contrary, the red LED is turned on at the pedestrian stop signal, and at the same time, the red LED is turned on when the person in the background is stopped. Before turning from the signal to the pedestrian progress signal, the seven red inverted triangle shapes are turned off one by one, and the traffic light indicating the time point to change to the pedestrian progress signal.

In general, traffic lights are used to indicate traffic conditions in color for safe traffic order. There are three colors, red, green, and orange, and red lights (hereinafter, "red lights"). ) Is a stop signal, green light (hereinafter referred to as "green light") is a progress signal, orange light is indicated as a caution, but road traffic means yellow (hereinafter referred to as "yellow light") means to bypass. Also used.

Such traffic lights are roughly classified into traffic lights using halogen lamps and traffic lights using light emitting diodes.

Among them, a reflector was installed at the rear of a halogen lamp as a light source, and a diffuser lens was installed at the front to diffuse light in various directions to reduce glare caused by the concentration of light.

In addition, a light shielding shade is installed above the diffusion lens to prevent sunlight from being reflected by a reflector installed therein, which makes it difficult to determine which signal light is turned on (phantom effect). It was supposed to prevent.

However, the conventional traffic light using such a halogen lamp has a problem that the surface of the diffusing lens should be cleaned regularly because of the shading shade cannot be expected to be natural, and therefore the maintenance cost for cleaning It was necessary. That is, on the road, tire dust generated by the friction between the tire and the road surface, carbides generated from the exhaust gas, and various dusts blown while driving the vehicle are adsorbed onto the surface of the diffusion lens, thereby reducing the transmittance of light. It can maintain the required light transmittance only by cleaning artificially or naturally, but in the past, the shading shade positioned above the diffusing lens blocks the rainwater, so natural washing could not be expected. There was a closure where the surface was stained.

In addition, even when the shading shade is installed, when the sunlight rays are shining toward the front of the traffic light, the faint phenomena, which are difficult to distinguish from the lit traffic light, are still generated because the light is transmitted inside and reflected by the reflector. .

Therefore, the shading shade must be installed for a longer time, and the long shading shade has a problem of lowering the recognition rate by blocking the light spreading to the side as well as blocking the light of the traffic light.

In addition, the lifespan of a signal lamp using a halogen lamp is very short, such as 5 months, which leads to a problem of high maintenance costs.In order to light a halogen lamp, a large current and a large voltage power supply are required. There was a problem of a possible safety accident.

On the other hand, in the case of a traffic light using a light emitting diode (LED), a large number of high brightness light emitting diodes are arranged on a printed circuit board at narrow intervals, and each light emitting diode has a current limiting resistor connected thereto. In front of it was a transparent protective cover.

However, in the conventional traffic light using the light emitting diode, the traffic light using the halogen lamp has a large number of parts because a plurality of light emitting diodes must be arranged on a printed circuit board and a current limiting resistor must be connected to each light emitting diode. There was a problem that the failure rate is configured to be high.

In addition, the power consumption of the signal lamp using a conventional halogen lamp is about 100 watts (W), the power consumption is very high, and the signal lamp using a light emitting diode displaying a number is a large power consumption because it uses a plurality of light emitting diodes, In addition, since the remaining time, or the person walking or stopping in the form of a GUI should be displayed in LED, the control circuit is somewhat complicated, and the power consumption is also high due to the large number of light emitting diodes used. have.

The present invention is composed of a plurality of inverted triangles in the vertical direction using LEDs that implement red and green, and then turn on the green LED in the pedestrian progress signal so that the pedestrian proceeds, and before changing from the pedestrian progress signal to the vehicle progress signal, By forming a group of inverted triangles formed by a dog and turning off a plurality of green inverted triangles arranged in a vertical direction in turn, it informs the time when it changes to a vehicle progress signal.On the contrary, the red LED is turned on in the vehicle progress signal, and the vehicle progress signal. Prior to the change to the pedestrian progress signal, a plurality of red inverted triangle shapes are sequentially turned off, and the purpose is to provide a traffic light indicating the time to change to the pedestrian progress signal.

In addition, the present invention is composed of a LED light and the display in a plurality of longitudinal directions, so that the large inverted triangle is turned off one by one at a time interval so that it can be identified from a distance, while at the same time configured to indicate the signal change green And it is the purpose to provide a traffic light that can be distinguished from a distance by configuring a red LED and simply configured to blink a plurality of inverted triangular shaped LED without any other configuration.

In addition, the present invention constitutes a red LED of a form in which a person configured in the background is stopped, and a red LED of a form in which a person configured in the background is stopped at the time of a pedestrian stop signal is also lit to distinguish red blind color blindness. The purpose of the present invention is to provide a traffic light configured to turn off the red LED of a stationary form when a pedestrian progress signal is turned on.

The present invention relates to a traffic light, and the seven inverted triangle lamps, in which a plurality of high-brightness LEDs displaying red and green light are arranged vertically, turns on in green and red in accordance with the walking signal and the walking stop signal, respectively. In the case of a stop signal, when a person who stops in the background in red in the background is composed of a pedestrian traffic light and a traffic light, the pedestrian traffic light is installed at an angle of 90 °, and the pedestrian traffic light is a progress signal. A vehicle auxiliary signal light configured to implement a red signal, flash a strong flashing signal once a second before the vehicle traveling signal, and then change it into a green signal, a timer for counting the flashing time of the pedestrian traffic light and the vehicle auxiliary signal, and a timer flashing The timer control unit can change the time interval setting, and time information can be received from the timer according to the time setting set in the timer control unit. It is controlled by a pedestrian traffic light and a flashing of the vehicle auxiliary light, and consists of a pedestrian traffic light and a vehicle control unit for controlling to operate the auxiliary light interlocked.

1 is a block diagram schematically showing the configuration of a traffic light installed in a crosswalk according to an embodiment of the present invention.

Referring to FIG. 1, the present invention includes a power supply 100, a timer 110, a timer adjusting unit 120, a control unit 130, a walking signal light 140, and a vehicle auxiliary signal light 160.

When the power source 100 is applied, the controller 130 controls the blinking time of the pedestrian traffic light 140 having high brightness LEDs capable of emitting green and red colors in the form of inverted triangles according to the setting of the timer adjusting unit 120. And interval settings.

In addition, the controller 130 operates in conjunction with a vehicle traffic light installed on the road. For example, when the vehicle auxiliary light 160 is displayed in green and is changed to a vehicle progress signal, the pedestrian traffic light 140 becomes a pedestrian stop signal displayed in red, and when the vehicle auxiliary light 160 is displayed in red, the pedestrian traffic light 140 ) Is displayed in green to be a pedestrian progress signal.

The pedestrian traffic light 140 is a high-brightness LED and is attached to one side of a traffic light, and the high-brightness LED is gathered to form an inverted triangle shape, and the inverted triangle shape has five to twelve, and the background is a human The high brightness red LED is formed in this stationary form. At this time, it is most preferable that the number of inverted triangles is seven. This inverted triangle displays red or green and turns off in order from the triangle above to indicate the time remaining. On the other hand, during the period in which the red inverted triangle is turned on, the red LED of the form in which the person configured in the background is stopped is turned on so that red-green color blindness can be distinguished from the on-time signal. At this time, the interval at which the red or green high-brightness LED of the inverted triangle shape is turned off is set at intervals of 3 seconds to 1 second, and most preferably at 2 seconds intervals.

In addition, the high-brightness LED constituting the traffic light so that both the pedestrian traffic light 140 and the vehicle auxiliary traffic light 160 may implement red light and green light has a red high brightness LED and a green high brightness LED in the same ratio. As a method of configuring this, the red high brightness LED and the green high brightness LED may be configured to be adjacent to each other, or each of the green LED and the red LED may be packaged as one LED.

The time at which the green and red high-brightness LEDs turn on in the pedestrian traffic light 140 blinks according to the timer 110 signal, and the flickering time is controlled by the timer 110 in the same manner. For example, in the one-way three lanes where the pedestrian crossing time is 25 seconds, the green display time is initially set to 25 seconds, and the inverse triangle LEDs are seven, and the interval in which the inverted triangle LEDs flash sequentially is set to two seconds. For the first 11 seconds, all triangles will turn green. For the remaining 14 seconds, the seven triangular scales are turned off one by one every two seconds.

On the other hand, if the control unit 130 inputs the time when the walking signal light 140 displays the green as the progress signal and the time when the red signal as the stop signal is input to the timer 110, the vehicle auxiliary signal light 160 operates accordingly accordingly. do. That is, when the pedestrian traffic light 140 displays red, the vehicle auxiliary traffic light 160 displays green, and when the pedestrian traffic light 140 displays green, the vehicle auxiliary traffic light 160 displays red.

In addition, the vehicle auxiliary signal light 160 is also configured to be attached to one side of the traffic light, and the traveling direction of the vehicle and the direction of the pedestrian to form an angle of 90 °, so as to form an angle of 90 ° with the pedestrian traffic light 140. do. On the other hand, when the pedestrian signal is displayed in green in conjunction with the pedestrian traffic light 140 as described above, the red stop signal is displayed, and after a strong flashing signal 1 second before the progress signal of the vehicle is changed to a green signal Implement if possible. The reason for the short implementation of such a strong flashing signal is to prevent an accident caused by the driver's predicted starting or starting.

In addition, while the vehicle auxiliary signal light 160 implements the green signal, which is the vehicle progress signal, the remaining time is changed from 5 seconds after the 5 seconds remaining from the vehicle progress signal to the red vehicle stop signal, 5-> 4-> 3-> 2-. Arabic numerals are displayed in the order of> 1-> 0 so that the driver can recognize the remaining time in advance so that accidents can be prevented by inducing slow motion before the stop signal.

Referring to FIG. 2A, first, as shown in FIG. 2, a state in which a high brightness LED configured in the vertical direction in the inverted triangle shape of the pedestrian traffic light 140 emits red light is illustrated. In addition, the red LED in the form of a stationary person in the background is turned on during the period when the red inverted triangle is turned on so that it can be more clearly informed that the time signal. This can be distinguished as a stop signal even in the case of red-green color blindness. If red is on as shown in Fig. 2A and the person shape is stopped, the pedestrian is in a stopped state as is known at this time. Here, each of the inverted triangular forms of the high-brightness LEDs in the pedestrian traffic light 140 forming a colony is seven, and it will be described assuming that the intervals of blinking are two seconds.

Referring to FIG. 2B, the state 9 seconds before the change from red to green is shown. In this case, two red inverted triangles are turned off. At this time, the red LED of the form in which the person comprised in the background is stopped also lights up. This red signal is a pedestrian stop signal.

Referring to FIG. 2C, the state 1 second before the change from red to green is shown. At this time, the red light of the six inverted triangles of the upper part is turned off, and the red high-brightness LED of the form in which a person is stopped is turned on. This is also a pedestrian stop signal. After 1 second has elapsed, the state will be as shown in FIG. 2D described later.

Referring to FIG. 2D, the state after time elapses for more than 1 second in the state of FIG. 2C. In this case, the color of the light represented by the inverted triangle forming a colony in the form of an inverted triangle of the walking signal light 140 becomes green. In this case, the red LED in the form of a stationary person in the background is turned off while the green inverted triangle is turned on so that the signal is clearly signaled. The signal at this time is a pedestrian running signal.

2E shows a state 9 seconds before the change from green to red. At this time, the green light of the two inverted triangles on the upper side is turned off, and as described above, the red high brightness LED of the form in which the human is stopped is also turned off. After 8 seconds have elapsed, the state will be as shown in FIG. 2F described below. As is well known, it is still a pedestrian progress signal.

2F shows the state 1 second before the change from green to red. At this time, only the lowest inverted triangle green color is turned off, and the red high-brightness LED in the form of a stationary person is also turned off. As is well known, it still displays a pedestrian progress signal. After 1 second has elapsed, it will be in the same state as in FIG. 2A described above. In this case, the red signal will be changed to a red signal, which is a pedestrian stop signal.

In the above-described embodiment, the flashing time has been described with a limited interval, but this is only assumed for convenience of explanation, and the flashing interval is a time for adjusting the timer 110 and the timer adjusting unit 120 to display a red signal or a green signal. It can be set freely within the range.

FIG. 3A shows a state in which a red light RL, which is a vehicle stop signal, is turned on to the vehicle assistance signal light 160 formed in this box shape. At this time, the shape of the red light is configured to be displayed in a circular shape so as to emit light similar to a conventional indicator light, so that there is no confusion in which the shape of the vehicle driver changes.

FIG. 3B is a view illustrating a state in which the vehicle auxiliary signal light 160 is displayed with a red light RL and then turned off (Null Light; NL), that is, a state in which a strong flashing signal flashes at regular intervals. To prevent starting and starting, flash once for 1 second only and change to green signal.

FIG. 3C illustrates a state in which the green light GL, which is a vehicle driving signal, is turned on in the vehicle auxiliary signal light 160 after the red light flashes once in FIG. 3B. At this time, the shape of the green light is also displayed in a circle like the red light so that there is no confusion for the driver of the vehicle.

FIG. 3D is a state in which the green light GL, which is a vehicle driving signal, is still on, but the circular shape disappears and is displayed as a number. In this case, the green light GL shows a state where the lighting time is 5 seconds remaining. After counting from 0 and strongly flashing, counting up to 0, it becomes '0' and at the same time turns red light RL as shown in FIG. 3A.

3A to 3D show the green light and the red light as time is counted by the vehicle auxiliary signal light timer 116, and blinks and time are displayed.

The present invention shows a pedestrian and driver the remaining time remaining in the crosswalk in the form of a large inverted triangle that can be identified from a distance, and the inverted triangle is turned off one by one to recognize the time when the signal is changed to make a more stable crossing for pedestrians. Providing sidewalk conditions, it improves safety and signal recognition rate while walking, contributing to the prevention of traffic accidents.

The present invention reduces the number of high-brightness LEDs installed in the crosswalk and simplifies the circuit configuration, thereby reducing frequent failures and drastically reducing installation costs and electricity costs, thereby contributing to budget savings.

According to the present invention, the high-brightness LED is composed of only one signal lamp which forms a group of inverted triangles, so that it is easy to maintain and manage as one signal lamp even when a failure occurs.

The present design consists of seven LED traffic lights configured to pedestrian traffic lights to emit green light, and then turn off from the top at a predetermined time interval within a predetermined time period to notify the end of the pedestrian progress signal. When a person walks or waits for a pedestrian signal, the pedestrian stop signal lights a red LED of a form where a person configured in the background is stopped so that the pedestrian stop signal and the progress signal can be clearly recognized. There is an effect that can clearly distinguish the progress signal and the stop signal.
