Description

Traffic safety indicator

The present invention relates to a traffic safety sign, and more particularly, to a traffic safety sign that prevents accidents while reducing maintenance costs.

In general, traffic safety signs are signs and signs indicating cautions, regulations, and indications regarding road traffic.

It is most important to secure visibility so that drivers and pedestrians can accurately identify the traffic safety signs.

Meanwhile, the contents of the traffic safety signs are indicated by reflecting materials reflecting light such as vehicles and street lights or fluorescent materials fluorescing to the light to ensure visibility even at night and in bad weather.

However, at night and in bad weather, it is very difficult to accurately identify the contents of the traffic safety sign at a distance. In particular, at night, the content of the traffic safety sign cannot be known unless light is reflected on the traffic safety sign.

As such, when the driver's visibility is shortened at night and in bad weather, and the driver does not correctly identify the traffic safety sign, it may cause the driver's safe operation and cause traffic accidents.

In recent years, even at night and in bad weather, light sources such as light bulbs, fluorescent lights, and light emitting diodes are displayed so that drivers and pedestrians can visually easily identify the contents of traffic safety signs.

However, in traffic safety signs such as electric bulbs and fluorescent lights, it is difficult to identify the contents of the traffic safety signs at a long distance due to scattering of light. In addition, since power consumption is high and life is short, frequent replacement is required, resulting in an uneconomical problem that requires a large amount of post-management.

In addition, a light emitting plate for arranging a plurality of light emitting diodes in a dot type is used for traffic safety signs of light emitting diodes. However, a costly light emitting diode is used so much that a manufacturing cost increases.

In particular, the light emitting diode has a disadvantage in that the discrimination is greatly reduced even if the driver's perspective angle deviates slightly from the front due to light scattering.

The present invention has been made to solve the above-mentioned problems. The present invention relates to a surface emitting structure in which light of low power, high brightness and semi-permanent light emitting diodes expresses the contents of a traffic safety sign through a plastic optical fiber provided in an injection window of a display panel. Therefore, the object of the present invention is to provide a traffic safety signage device which greatly improves visibility without regard to perspective angle.

In addition, an object of the present invention is to provide a traffic stability display device to facilitate the maintenance by self-luminous by using the natural sun.

Another object of the present invention is to provide a traffic safety display device which prevents an accident of a driver in the event of sudden darkening by a shower or the like by automatically emitting light according to illuminance.

Traffic safety display device according to the present invention for achieving the above object consists of a light collecting unit for converting the light emitted from the sun into electricity, and a light emitting diode for emitting light by receiving the electricity converted in the light collecting unit A light emitting part, a plastic optical fiber made up of a plurality of strands surrounding the light emitting part and transmitting the light emitted from the light emitting part in a straight direction, and the ends of each plastic optical fiber are inserted and fixed to display letters, numbers, and models. A display panel on which a plurality of holes are formed, an illuminance measuring unit configured to measure ambient illuminance, and a main control unit configured to adjust brightness while turning on / off the light emitting unit according to a result measured by the illuminance measuring unit; Characterized in that the configuration.

Traffic stability display device according to the present invention has the following advantages.

First, low power, high brightness and semi-permanent light emitting diodes display visibility of traffic safety signs through the light emitting material layer provided on the display panel's exit window. It can enhance the driver's mental stability and create beautiful city scenery.

Second, it is possible to reduce the maintenance cost for road lighting by emitting light using solar cells, which are natural energy.

Third, unique road scenery with regional characteristics can be created by directing night road lighting.

Fourth, it can provide a safe environment of vehicle operation from injuries and obstacles scattered in the dark space.
