Description

Environmentally friendly and non-electric dynamic traffic signal sign

The utility model relates to a traffic signal signboard, in particular to a traffic signal signboard which realizes a dynamic visual effect according to an optical principle. Reduce the need for traffic accidents on an environmentally friendly basis because no additional power is required

With the widespread use of various motor vehicles, traffic safety issues have become a common concern of governments and the public. According to relevant statistics, more than 1.2 million people worldwide die from road traffic accidents every year.

In the cause of traffic accidents, the driver's lack of concentration or low alertness is a very important factor that cannot be ignored. The lack of attention to the traffic signal signs is an important reason for the driver's lack of awareness. Studies have shown that dynamic traffic signal signs are more conspicuous, which can improve the driver's alertness to road conditions, and when seeing a traffic warning sign with a strong dynamic, the driver's response speed will be significantly accelerated.

Traffic signal signs can basically be divided into two types: dynamic traffic signal signs (such as traffic light traffic lights) and static traffic signal signs (such as "school roads" traffic signal signs). At present, dynamic traffic signal signs generally need to be connected to a power source, and serve as a warning by emitting different colors of lights and different patterns. Because of the need to connect power, they can only be used in certain specific places (such as intersections), and Consume power. The static traffic signal sign generally does not need to be connected to the power supply, so the use of the venue is more extensive, but the warning effect is worse than the dynamic traffic signal sign.

In view of the above, it is necessary to provide a traffic signal sign that can balance the warning effect and environmental protection so as not to be restricted by the power source, and can be deployed on the roadside in various situations, so that the driver is more alert to the road conditions at that time. Thereby reducing the occurrence of traffic accidents.

The utility model relates to a traffic signal signboard which realizes a dynamic visual effect according to an optical principle, and does not need to be connected to a power source, so it is more environmentally friendly.

The utility model is composed of three parts: a pedestal layer, an image mosaic layer, and a grating layer.

The pedestal layer is made of metal or other material and is the innermost layer of the traffic sign, providing a frame for the entire traffic sign and maintaining a certain hardness.

Two or more traffic sign images are printed on the image mosaic layer, and are divided into a plurality of small regions by equidistant parallel lines, each of which is printed with a portion of one of the images. In the adjacent small area, each traffic sign image alternates. Each traffic signal logo pattern is close but nuanced.

The pedestal layer and the image splicing layer may be combined into one layer, that is, a traffic sign image is printed on the pedestal layer, which also serves as an image splicing layer.

The grating layer is formed on the image splicing layer by using a transparent material, and the upper surface is scribed with a dense parallel groove, and the parallel groove is a grid composed of a semi-cylindrical body, a semi-elliptical cylinder or a multi-faceted cylinder, and the width thereof It is proportional to the parallel line of the image mosaic layer. The grating layer and the image stitching layer are tightly pressed together. According to the optical principle, the grid of each grating can refract the image light of the image mosaic layer below, and the refractive angle of the light is different for different parts of the grid of a single grating. At a certain angle, only one of the several traffic sign images of the image mosaic layer can be seen by the observer through the grating; when another angle is changed, another different image of the image mosaic layer can be observed through the grating. See it. When the observer or the driver is in a moving state, since the angle of the relative traffic signal sign is changing, different images on the image mosaic layer are continuously seen, thereby seeing the dynamic traffic signal sign.

Figures 1 - 5 illustrate an implementation of the present invention.

The implementation method will be further described below with reference to Figs.

In Fig. 1, 1 is a pedestal layer, 2 is an image splicing layer, and 3 is a grating layer. The pedestal layer provides a frame for the entire traffic signal sign; the image splicing layer is printed with two or more patterns; the grating layer is made of a transparent material with equal spacing of parallel parallel grooves, and the parallel grooves are semi-cylindrical, A grid consisting of a semi-elliptical cylinder or a multi-faceted cylinder, and the angle of refraction of the image light of the image mosaic layer is different for each different part. The pedestal layer and the image stitching layer can also be combined into one layer, that is, the traffic signal mark is printed on the pedestal layer.

The image stitching layer is illustrated in Figure 2. The image stitching layer is divided into a plurality of small areas by equidistant parallel lines, each of which is printed with a portion of one of the images. Only the scene in which two patterns are printed is shown here: after the entire image mosaic layer is divided into a plurality of small areas, the areas of the display pattern A and the display pattern B alternate.

A schematic diagram of the image mosaic layer display pattern A is illustrated in FIG. The arrow pattern A in the figure is printed on each A area (solid line portion), and the B area has no printed pattern A (the dotted line portion does not need to be printed).

A schematic diagram of the image mosaic layer display pattern B is illustrated in FIG. The arrow pattern B in the figure is printed on each B area (solid line portion), and the A area has no printed pattern B (the dotted line portion does not need to be printed). The traffic signal signs represented by pattern B and pattern A have some subtle differences in position and shape size.

In Fig. 5, when the driver drives the car through the position 1, due to the angle of refraction of the grating layer, only the pattern A of the traffic signal sign can be seen from the position of the position 1. When the car reaches position 2, the angle with respect to the grating layer changes, so only the pattern B of the traffic signal sign can be seen from the position of position 2. Since there are some differences between the pattern A and the pattern B, from the perspective of the driver, he sees a dynamic traffic signal sign, thereby increasing the alertness and the reaction speed.
