Abstract

The present invention relates to a U-turn signal system that displays a U-turn signal, a stop signal, a U-turn signal countdown time, and a stop signal countdown time using LED lighting or lighting intended for a general signal light, thereby providing more detailed U-turn traffic information to drivers as compared to existing fixed-panel U-turn traffic signal systems.

Description

U-turn signal light

Currently, the u-turn signal system displays a fixed panel engraved with a u-shape and a fixed panel that informs the time when the u-turn can be made according to the road conditions such as [when turning left, when turning left and when walking].

As a result, many factors, such as poor visibility, poor vision, and unfamiliar geographic requirements, often lead to confusing situations.

BACKGROUND OF THE INVENTION The background art of the present invention is a multi-color LED light, or a monochromatic LED light, or a light for a general signal lamp, a control technique thereof, and a signal analysis system.

The present invention incorporates the concept of a traffic light to the u-turn display, a u-turn stop signal and a u-turn progress signal, and each signal as a signal light composed of a multi-color LED light, or a monochromatic LED light, or a general signal light, which is often developed around the u-turn display. It provides a u-turn traffic light system that notifies the driver until the remainder of the vehicle's time, helping to make traffic flow smoother.

Optimize the software and hardware to match the popular traffic light system.

As described above, the present invention can provide a clearer traffic signal to the driver by replacing the existing u-turn display panel with a traffic light, thereby enabling the driver to predict a signal change time.

5 is an embodiment of a multicolor LED traffic light. By using multi-color LED, it lights up in red when stop signal, and in green when u-turn is possible, and the remaining time indication of each signal is displayed by text. In addition, FIG. 5 may be configured by using a monochromatic LED or general lighting to display only when the U turn is possible.

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

2, 4, and 5 shows a U-turn signal light using multi-color LED lighting,

3 is an exemplary view of the configuration of a u-turn signal lamp using monochromatic LED lighting or general traffic light lighting.

Mainly explaining how to use multi-color LED,

As shown in Fig. 1, the present invention receives the signal information data output from the external traffic signal control means 101, calculates the flashing of the u turn disable (stop) signal and the u turn enable signal, and calculates the remaining time of each signal. And control means 102 for centrally controlling each function of the system.

It is composed of multi-color LED all-optical panel and displays green u-turn image and remaining time when u-turn signal according to control signal of control means.

In the case of the stop signal, u-turn LED signal lamp 120 displaying a red stop signal image and the remaining time of the stop signal;

According to the control signal of the control means

In the case of stop signal, the remaining time of stop signal and stop signal is displayed by number, letter or figure,

In the u-turn signal, the u-turn signal and the LED control means 105 for controlling the operation of displaying the remaining time in numbers, letters or figures.

When the control means transmits a control signal to the LED control means 105, the LED control means lights up the LED constituting the stop signal display image in red and at the same time, the remaining time is set numerically or graphically by the signal remaining time setting means 108.

The remaining time of the u turn prohibition time is displayed by the red LED by the time display means 109.

When the control means 102 receives the u-turn signal from the external signal controller, the LED on the u-turn signal display image lights up in green in the same manner as described above, and the remaining time is set numerically or graphically by the signal remaining time setting means 111. The remaining time is displayed on the displayed time display means 113.

Looking at the embodiment of the configuration of the U-turn signal lamp using the multi-color LED light of Figures 2, 4, 5,

2 is a method of converting a U-shaped (n-shaped) arrow image into red and green to distinguish between U-turn enabled and impossible signals, and placing a residual time display image around the U-shaped (n-shaped) arrow image. In the present embodiment, the remaining time display image may be displayed numerically.

4 is a method of partitioning a U-shaped (n-shaped) arrow image itself so as to sequentially disappear or convert to another color in correspondence with the remaining time.

4 is a method of manufacturing a multi-colored led panel in the shape of a u-shaped (n-shaped) arrow.

As shown in FIG. 3, when the U turn signal panel is composed of a green and red monochromatic LED or two green and red general signal lamps, a stop signal and an LED display unit or two general signal lamps constituting an image of the u turn signal are shown. The remaining time display part is composed of LED or general traffic light.

5 is an embodiment of a multicolor LED traffic light. 5 may be configured by using a monochromatic LED or general lighting to display only when U turn is possible.

As those skilled in the art can make various modifications with reference to the technical spirit and embodiments of the present invention, the scope of the present invention should be interpreted based on the description of the claims.

It is possible to contribute to the development of the road traffic signal industry because the driver's convenience can prevent traffic accidents and infer good traffic.
