Abstract

This design is a signal system that can be recognized easily by the driver than the signal system of the existing traffic lights and can be easily recognized by the color blinders. Conventional traffic lights indicate a signal with a color change of green (progress), yellow (caution), and red (stop) by circular lighting. However, in addition to the signal system (circular green: progressive, triangular yellow: attention, X red: stop) with the shape of the present invention, white LEDs and blank intervals were put in the middle of the equalization to allow immediate recognition.

Description

{Traffic lights with easy-to-understand shapes}

      The present invention is a traffic light that more clearly recognizes a signal to a driver than an existing traffic light. The driving signal is a blue circle, the warning signal is a yellow triangle, and the stop signal is a red X-type. A figure with a difference in brightness is arranged inside each light to help the driver easily recognize the signal.

The present invention relates to a traffic light which is easy for a driver to perceive, and more particularly, a traffic light which supports the driver to clearly recognize a traffic signal in a different shape according to the signal state of the traffic light.

Generally, the traffic lights are based on three colors of red, yellow and blue, and there is an arrow indicator that indicates the direction in which progress can be made. Therefore, the driver operates the vehicle according to the signal state of the traffic light.

The current signal system consists of green (straight), red (stop), yellow (attention) and green arrows (left, right). The driver needs to be able to grasp the signal in a short time, so it needs a signal light to judge at a glance without the time to think, so the present traffic light needs improvement.

Also, for people with color vision problems, it may be a problem to display signals only in this color. Hue blinders are often adapted to learn by learning, for example, by memorizing the signal position of a traffic light. However, in such cases, it is easy to be at risk because it is difficult to respond quickly to the situation. Also, when a traffic accident occurs, a victim or an eyewitness may not be able to make an accurate judgment. The traffic lights designed for these color vision defects also consider only the red light color anomaly, which is the middle color of the total color hue, and do not consider the cases of the blue color hue and full color hue.

In the case of children who can not give meaning to the color, it is difficult to understand the traffic signal as a circular lighting signal that displays the signal only in the present color.

Therefore, the present invention intends to devise a traffic light that can easily grasp the signal at a glance, and can judge the signal system without any confusion, including all persons with a color vision abnormality including a red color vision abnormality.

In the present invention, the shape of the traffic light is changed and the color of the existing signal display is maintained, so that the traffic light is designed to easily grasp the meaning of the signal without giving a sense of heterogeneity to the existing driver.

In addition, the present invention is differentiated from existing products that only changed the appearance of the traffic light, and added a symbol to make it possible to distinguish the signals effectively. The higher the contrast of brightness and the greater the contrast of saturation, the more noticeable the effect of the two colors. The white color with high brightness is assigned to the relatively low-light red and green, and the low- Color symbols were arranged.

The effect of the easy-to-recognize graphic signal lamp according to the present invention described above will be described as follows.

First, the external shape of the signal light and the internal figure are marked as circular, the triangle in the caution signal, and the X symbol in the stop signal, so that the driver can quickly connect the signal and the meaning Respectively.

Second, the inner figure of low green signal has a high lightness white color and the inner figure of high lightness yellow signal has low lightness black.

Third, the development of the signal lamps for the red - color - anomaly is also able to improve the non - beneficial blue and yellow color signals.

Fourth, children who have difficulty in understanding the meaning of color through the transmission of meaning through easy - to - understand shapes can easily understand traffic signals.

In the present invention, when the signal state of the signal lamp is a progress signal, the control section of the signal lamp displays a plurality of green LED elements 15 in a circular form to display (44), and has a different brightness The white identification LED element 16 is turned on.

When the signal state of the signal lamp is a stop signal, a plurality of red LED elements 11 are displayed in an X-letter form to be displayed (40), and furthermore, white identification LED elements 12) is also turned on in the X-shape (40).

When the signal state of the signal lamp is in the state of caution, the control section of the traffic light displays a plurality of yellow LED elements 13 having a triangular blank section 14 disposed therein in the form of a triangle (42) For ease of operation.

Conventional traffic lights with red, green, and amber lights made it difficult to identify the signal in a short time. In this design, the color of the existing signal display is maintained while adding visual figures, thereby reducing the sense of heterogeneity. Therefore, it does not confuse existing drivers. In addition, it is easy to install because it only needs to replace the LED part while maintaining the standard in the existing traffic light.
