Alternatively, the storage unit 21, the timer 27, and the control unit 29 may be installed near the column 10, and may be installed in a control box for controlling the crosswalk traffic light device 100 and the vehicle traffic light device.

The storage unit 21 stores a program necessary for controlling the operation of the traffic light device 100 for crosswalks and information generated while the program is executed. In particular, the storage unit 21 stores an execution program for controlling the operation of the LED lighting unit 25 and the pedestrian traffic light 23 according to the walking-related signal according to the signal of the timer 27.

The pedestrian related signal may include a pedestrian ready signal according to a pedestrian preparation cycle, a pedestrian permission signal according to a pedestrian permission cycle, a pedestrian warning signal based on a pedestrian warning cycle, and a pedestrian disabled signal according to a pedestrian-free period. The walk preparation signal is a signal for informing the driver and the pedestrian before going to the walking permit in a state where it is impossible to walk through the crosswalk 85. For example, the walking ready signal may correspond to a signal when the vehicle traffic light changes from green to yellow. The walking permission signal is a signal for allowing walking through the crosswalk 85. The walking warning signal is a signal for notifying the driver and the pedestrian before the walking permission signal is passed from the walking permission signal. The no-walk signal is a signal that does not permit walking through the crosswalk 85.

The pedestrian traffic light 23 is installed on one side of the column 10 facing the pedestrian crossing 85 to display walking permission, walking warning, and impossibility of walking. For example, the pedestrian traffic light 23 may include a first walking light 23a, a second walking light 23b, and a remaining walking time light 23c. The first walking indicator light 23a lights up in response to a walking impairment signal to indicate that walking is impossible. The second walking indicator light 23b is provided below the first walking indicator light 23a, is turned on in accordance with the walking permission signal, and blinks in accordance with the walking warning signal to display the walking permission or the walking warning. The remaining walking time indicator 23c is located above the first walking indicator 23a or below the second walking indicator 23b, and displays the remaining time for walking through the crosswalk 85. . In this case, the walking remaining time indicator 23c may display the remaining time by a number or a plurality of bar patterns. In the present embodiment, an example in which the walking remaining time indicator 23c is positioned below the second walking indicator 23b and the remaining time is indicated by numbers is disclosed.

The LED lighting unit 25 is installed at the upper end of one side of the column 10, the pedestrian traffic light 23 is installed to illuminate toward the crosswalk 85, to produce a plurality of colors. For example, the LED lighting unit 25 can produce light by outputting white, red, yellow, and green light, but is not limited thereto. LED lighting unit 25 is installed on the upper end rather than the pedestrian traffic light 23 to illuminate the crosswalk (85). The LED lighting unit 25 includes a plurality of LEDs arranged in an array on a substrate, and the plurality of LEDs are installed so that the light output surface 25 for outputting the LED light 31 faces the crosswalk 85. It is installed at the top of the. At this time, the LED lighting unit 25 is installed so that the light output surface 26 forms an acute angle with the surface of the crosswalk 85 so as to stably illuminate the crosswalk (85). The light output surface 26 may adjust the light output surface 26 up, down, left, and right angles through an electric or manual angle adjustment member provided at the rear of the light output surface 26. The LED lighting unit 25 may irradiate the LED light 31 to a region between the column 10 and the center line 89 of the road 81 where the pedestrian crossing 85 is formed.

The right turn signal 30 is installed on the other side of the column 10, it can indicate whether or not the right turn of the vehicle 60. Here, the other side of the column 10 is a surface that the driver of the vehicle 60 can see. The right turn signal light 30 may include a first indicator light 30a indicating a right turn, a second indicator light 30b prohibiting a right turn, and a third indicator light 30c allowing a right turn. The light 30a, the second indicator 30b, and the third indicator 30c may be disposed in this order. In this case, the letter “right turn” may be displayed on the first indicator 30a, and may be always displayed. The second indicator 30b may be displayed as "prohibited" or ",", and may be turned on when a signal related to walking, except for a signal that is unable to walk, is displayed. "Go" or "→" may be displayed on the third indicator 30c, and may be turned on when a signal for walking is impossible. Only one of the second indicator light and the third indicator light 30b, 30c is displayed.

The right turn signal 30 may be selectively installed only in the column 10 is installed on the sidewalk with a road that can turn right. In the general straight road 81, the right turn signal lamp 30 is not installed in the column 10.

In the present embodiment, the right turn signal 30 is an example in which the first to third indicators 30a, 30b, and 30c are disclosed, but the present invention is not limited thereto. For example, the right turn signal 30 may be configured with one light indicating the right turn and another light indicating whether the right turn is allowed or not. Alternatively, the right turn signal 30 may be configured as one indicator indicating whether the right turn is allowed or not.

The guide display 40 is installed on the surface of the column 10 to guide or display the main facilities, motto, promotional materials around. The guide display 40 may include a main facility guide sheet 41, a slogan and promotional article attaching sheet 43, and a local mark 45. Here, the main facility guide sheet 41 displays information on major public offices, organizations, buildings, etc., located near the crosswalk 85. Area mark 45 indicates the area, for example, ** city, ** group, etc. in which the corresponding crosswalk traffic light device 100 is installed.

The voice output unit 50 is installed in the column 10 and outputs a voice guidance according to the walking permission, walking warning or walking impossibility. For example, the voice output unit 50 outputs a voice guide according to a walking-related signal for the visually impaired so that the visually impaired can cross the crosswalk 85 safely.

The timer 27 outputs a signal according to the arrival of the walk preparation cycle, the walk permission cycle, the walk alert period, and the walk impossible period to the controller 29. At this time, the timer 27 provides information about time so that the controller 29 can perform a control operation for the traffic light device 100 for pedestrian crossing according to the walking related signal. In addition, the timer 27 may simply count the current time and output current time information to the controller 29. Pedestrian preparation cycles are pedestrian-related cycles located between pedestrian cycles and pedestrian permit levels. The gait preparation phase, the walk permission cycle, the walk alert period, and the walk impaired cycle arrive repeatedly in a cyclic manner in time series, and the timer 27 checks whether the corresponding cycle has arrived and transmits it to the controller 29.

In addition, the controller 29 is a microprocessor that performs an overall control operation of the traffic light apparatus 100 for pedestrian crossing, and performs a process according to a walking related signal. In particular, the controller 29 controls the driving of the LED lighting unit 25 according to the walking-related signal. That is, when the controller 29 receives a signal according to the walking permission cycle through the timer 27, the controller 29 illuminates the crosswalk 85 in the first color through the LED lighting unit 25. When the control unit 29 receives a signal according to the walking alert cycle after the walking permission cycle, the controller 29 changes the pedestrian crossing 85 from the first color to the second color through the LED lighting unit 25 and illuminates it. When the control unit 29 receives a signal according to a non-walking cycle after the walking alert period, the controller 29 changes the pedestrian crossing 85 from the second color to the third color through the LED lighting unit 25 and illuminates it. In addition, when the control unit 29 receives a signal according to the walking preparation cycle after the no-walking cycle, the crosswalk 85 is changed from the third color to the fourth color through the LED lighting unit 25 to start the illumination. Of course, when the control unit 29 receives a signal according to the walking permission cycle in the walk preparation cycle, the controller changes the pedestrian crossing 85 from the fourth color to the first color through the LED lighting unit 25 and illuminates it.

In this case, after the controller 29 informs the vehicles 60 stopped at the pedestrian crossing 85 in a third color visually, the controller 29 prevents the driver's view due to the third color. Through the LED lighting unit 25, the crosswalk 85 is turned off after a predetermined time illumination in a third color. In this case, the predetermined time may be several seconds.

In addition, the LED lighting unit 25 may output the same color as the second and fourth colors under the control of the controller 29. For example, the LED lighting unit 25 may output white or red as the first color, yellow as the second and fourth colors, and green as the third color under the control of the controller 29.

In addition, the control unit 29 outputs a pedestrian-related signal to the pedestrian or driver through the pedestrian traffic light 23. That is, the controller 29 displays the walking permission through the pedestrian traffic light 23 when the walking permission cycle comes. The controller 29 changes the walking permission to a walking warning through the pedestrian traffic light 23 when the walking warning cycle comes. The controller 29 changes the pedestrian warning to pedestrian through the pedestrian traffic light 23 when the pedestrian cycle becomes impossible. At this time, when the walking permission period is reached, the control unit 29 turns off the second walking indicator light 23b and turns on the first walking indicator light 23a. When the walking warning period is reached, the control unit 29 blinks the first walking indicator light 23a. When the period of no walking is reached, the control unit 29 turns off the first walking indicator light 23a and turns on the second walking indicator light 23b. The walking remaining time indicator 23c indicates the remaining walking time during the walking permission cycle and the walking warning period.

Meanwhile, in the present exemplary embodiment, an example in which the controller 29 controls the LED lighting unit 25 according to a walking related signal to fix a predetermined area of the crosswalk 85 is fixed, but is not limited thereto. When the LED lighting unit 25 is provided with a rotation control member that rotates the light output surface 26 electrically, the control unit 29 rotates the light output surface 26 at a predetermined angle up or down or left and right according to a walking related signal. It is also possible to output the LED light 30 while. Compared to illuminating the crosswalk 85 fixedly through the LED lighting unit 25, the area where the LED light 31 is irradiated onto the crosswalk 85 is enlarged by rotating the LED light 31 up and down or left and right. Therefore, it is possible to more effectively communicate the walking-related signal to the driver.

Meanwhile, the pedestrian crossing traffic light apparatus 100 according to the present exemplary embodiment may check the current time through the timer 27 and determine whether to drive the LED lighting unit 25 according to the time. For example, in the daytime period, the surrounding area is bright, and thus, the efficiency of transmitting the walking-related signal to the driver by the illumination of the LED lighting unit 25 is low, so that the control unit 29 does not drive the LED lighting unit 25 even when the walking-related signal is input. Do not. On the other hand, in the case of the night time zone, the surroundings are dark, so that the walking-related signal can be effectively transmitted to the driver by the illumination of the LED lighting unit 25, and the controller 29 drives the LED lighting unit 25 according to the walking-related signal.

Alternatively, the pedestrian crossing traffic light apparatus 100 according to the present embodiment may further include an illuminance sensor. The illuminance detector detects the illuminance around the pedestrian crossing traffic light device 100 and transmits the detected illuminance to the controller 29. The driving of the LED lighting unit 25 may be determined according to the illuminance sensed by the controller 29. For example, in the daytime with high illumination, the controller 29 does not drive the LED lighting unit 25 because the lighting effect is not great even if the LED lighting unit 25 is driven. If the illuminance is low, such as at night, the controller 29 may drive the LED lighting unit 25.

A crosswalk illumination method of the crosswalk traffic light device 100 having the LED lighting unit 25 according to the present embodiment will be described with reference to FIGS. 1 to 5 as follows. 5 is a flowchart illustrating a crosswalk illumination method of the traffic light device 100 for a pedestrian crossing having the LED lighting unit 25 according to the embodiment of the present invention. Here, the pedestrian crossing traffic light device 100 operates in conjunction with the pedestrian traffic light 23 and the right turn indicator 30 according to a signal input from the timer 27. Since the operation of the pedestrian traffic light 23 and the right turn indicator 30 is made in the same manner as the operation of the general pedestrian signal and the right turn indicator, detailed description thereof will be omitted. The traffic light device 100 for a pedestrian crossing will be described based on a method of illuminating the pedestrian crossing 85 by operating the LED lighting unit 25 according to a signal input from the timer 27.

First, the traffic light device 100 for pedestrian crossing starts in the standby state according to step S81. At this time, the standby state means maintaining the operation state of each LED lighting unit 25 according to the walk preparation cycle, the walk permission cycle, the walk warning cycle and the walk impaired cycle.

Next, at step S81, the traffic light apparatus 100 for pedestrian crossing determines whether a signal is received from the timer 27. That is, the traffic light apparatus 100 for pedestrian crossing determines whether a signal corresponding to the arrival of the walk preparation cycle, the walk permission cycle, the walk warning period, and the walk impossibility period is received from the timer 27.

If no signal is received from the timer 27 as a result of the determination in step S83, the standby state according to step S81 is maintained.

When a signal is received from the timer 27 as a result of the determination in step S83, the traffic light apparatus 100 for pedestrian crossing in step S85 determines whether the signal is a signal.

If the signal is a walk ready signal according to the walk preparation cycle, in step S87, the traffic light device for pedestrian crossing 100 operates the LED lighting unit 25 to illuminate the fourth color with the pedestrian crossing 85 to crosswalk the driver. (85) tells you in advance that pedestrians will cross.

Alternatively, when the signal is a walking permission signal according to the walking permission cycle, the traffic light device 100 for pedestrian crossing in step S89 changes the fourth color to the first color through the LED lighting unit 25 to the pedestrian crossing 85. Illuminate. As a result, the driver can easily confirm that the walking permission signal is obtained from the illumination of the first color of the LED lighting unit 25.

Alternatively, if the signal is a walking warning signal according to the walking warning cycle, the traffic light device 100 for crosswalks in step S91 changes the first color to the second color through the LED lighting unit 25 to the crosswalk 85. Illuminate. In this case, the LED lighting unit 25 may illuminate the crosswalk 85 by blinking the second color. As a result, the driver may know in advance through the second color that the walking of the pedestrian through the crosswalk 85 will be terminated.

Alternatively, when the signal is a no-walk signal according to the no-walking cycle, the traffic light device 100 for crosswalking changes the second color to the third color through the LED lighting unit 25 in step S93 to change the crosswalk 85. Illuminate. As a result, the driver can easily confirm through the third color that the driver can travel across the crosswalk 85.

Next, in step S95 after the step S93, the traffic light device 100 for pedestrian crossing determines whether a predetermined time has elapsed.

When the predetermined time has not elapsed as a result of the determination in step S95, the traffic light device 100 for pedestrian crossing maintains the third color illumination state according to step S93.

If a predetermined time elapses as a result of the determination in step S95, the traffic light device for pedestrian crossing 100 turns off the LED lighting unit 25 in step S97.

Here, the traffic light device 100 for crosswalks includes a fourth color light according to step S87, a first color light according to step S89, a second color light according to step S91, a third color light according to steps S93 to S97, and The lights are turned off repeatedly in time series according to the gait preparation phase, the walking permission cycle, the walking warning cycle, and the non-walking cycle, respectively.

In operation S99, the traffic signal device 100 for crosswalking determines whether an end signal is input, and if not, performs the process again from operation S81. In this case, the traffic light device 100 for pedestrian crossing maintains the state according to the non-walking cycle. The end signal may be a case where a power-off signal is input to the pedestrian crossing traffic light apparatus 100.

As such, the LED lighting unit 25 may illuminate the pedestrian crossing 85 in various colors according to the pedestrian-related signal to visually inform the driver of the pedestrian-related signal while allowing the pedestrian to safely cross the pedestrian crossing 85. In particular, a driver in a blind spot where the pedestrian traffic light 23 or the vehicle traffic light cannot be identified can visually check the lights of various colors irradiated from the LED lighting unit 25, so that a safety accident occurs in the crosswalk 85.
