Abstract

The present invention relates to an LED signal display device for attaching an advanced sidewalk signal lamp which displays not only the green walking signal but also the remaining time of red walking prohibition signal in one LED device in a pedestrian crossing traffic light system. The present invention provides an apparatus and technology for converting an existing pedestrian crossing signal system into an advanced pedestrian crossing traffic light system by simply attaching it to an existing pedestrian crossing signal system so that pedestrians can predict the remaining time of signal change by themselves. In addition, the display panel provides a technology for dramatically reducing the cost of a pedestrian crossing signal while simultaneously implementing a green and red display function of a pedestrian crossing signal light and a function of displaying a pedestrian remaining time and a pedestrian remaining time.

Description

Apparatus for indicating the remaining time of green signal & red signal for crossroad.

The present invention was filed on June 21, 2002, and registered as a utility model No. 0 289229 on September 2, 2002, and was registered and maintained by technology evaluation on March 31, 2004. It is a continuous improvement application of a display LED device.

The present invention relates to a device for pedestrian crossing traffic light system, which is attached to the existing pedestrian crossing traffic light so that the pedestrian can predict the remaining flashing time of the green signal time and the red signal time on one display panel.

In the conventional pedestrian crossing traffic light, the remaining blinking time is signaled by blinking the green signal and the LED bar (BAR) method for displaying the remaining time of signal change when the green walking signal is used. All had to predict the blinking time of the green traffic light, but it was inconvenient to predict how much pedestrians would have to wait to change from red to green.

In the open technology of this field, it is only common sense that the remaining time of pedestrian traffic lights is displayed by numbers, voices, or LED signals, and a single display device has been developed to display the remaining time of blinking green and red signals. If you look at a conventional crosswalk traffic light, it is only a BAR that displays and displays the remaining time when it is green. The trend is changing from the conventional light signal system to the energy-saving LED signal system, and the pedestrian desires to display not only the remaining walking time but also the remaining walking time is increasing. It provides a technology to drastically improve a pedestrian signal system by developing a device that combines a pedestrian signal and (ii) a pedestrian remaining time, (iii) a pedestrian signal and (iv) a pedestrian remaining time.

Hereinafter, with reference to the accompanying drawings will be described the system configuration of the present invention for achieving the above object and its effects and effects.

1 is a system block diagram of the present invention. As shown in Fig. 1, the present invention provides a plurality of green LED means 11-1, 11-2, ..., 11-n, which represent the shape of a two-digit number; Red LED means (12-1, 12-2, ..., 12-n) for displaying the shape of a plurality of two-unit numbers cross-configured between the green LED in red; Green LED control means 14 for sequentially displaying a walking time when the green light is turned on in the green LED means by a green LED number, and controlling the LED to be turned off when the green light is turned off; Red LED control means (13) for sequentially displaying the prohibition of walking when the red light is turned on in the red LED means in red LED numbers and for turning it off together when the red light is turned off; An existing green traffic light 15 for connecting the green LED control means 14; An existing red traffic light 17 for connecting the red LED means 13; Consists of the existing sidewalk traffic light control device 18 to control and supply the red traffic light and the green traffic light.

As described above, when the sound signal oscillation device for the visually handicapped device is attached to the present invention, it is attached to the green timer means, and the sound signal combines two or more melodies or signals to change the time of the traffic light due to the difference in the oscillation time interval between the signals. Foretell

In the above configuration, when the numeric display LED color is yellow or white, that is, a LED indicating a third color other than red or green, one remaining time display device is used to display the remaining pedestrian waiting time and the banned walking time. Mark as combined.

In addition, by configuring the display panel on the time display device of the third color above with a red LED and a green LED, the display panel is displayed in red when the pedestrian remaining time is displayed, and the display panel is displayed when the remaining time is displayed. If it is displayed in green, even if the pedestrian traffic light is removed, the pedestrian traffic light function is implemented as a single time display panel. In addition, when constructing a pedestrian light with a separate LED panel in addition to the above time display device, a red LED and a green LED are alternately configured on one LED panel to realize red and green colors by using one display panel. When the red LED is displayed, animation that indicates no walking or characters such as "STOP" or "Stop" can be displayed together.When the green LED is displayed, the animation to walk, "WALK" or " "Walk", etc. can be implemented with LEDs of different colors.

In addition, when the LED panel is configured relatively large, not only the pedestrian remaining time or the pedestrian remaining time is displayed, but also various information such as image generator and character generator, etc. It provides the next generation pedestrian traffic light system that implements advertisements in flowing text.

As described above, the present invention is attached to the existing pedestrian crossing traffic light system and displays the remaining time of blinking green traffic light and the remaining time of blinking red traffic light by using a single LED device to predict walking time or waiting time for signal change. It provides a useful device that can be used at low cost to retrofit existing pedestrian crossing signaling systems to signal change remaining time notice. In addition, a single LED display panel displays the pedestrian signal and the pedestrian signal, the remaining pedestrian time and the pedestrian remaining time, and the red and green lights, the pedestrian remaining time display device and the pedestrian remaining time display device. Existing pedestrian traffic light system consisting of a single light (display panel) is implemented to reduce the cost of the pedestrian traffic light system.

In addition, the display panel is made relatively large so that the lower part of the panel displays a pedestrian crossing signal, a pedestrian remaining time and a pedestrian remaining time, and displays information or advertisements to pedestrians or pedestrians with letters or animations flowing at the top of the panel. It provides the next generation pedestrian signal system that can be provided.
