Description

Traffic safety marker using light emitting diodes {TRAFFIC SAFETY MARK DEVICE USING LIGHT EMITTING DIODE}

The present invention relates to a traffic safety label device using a light emitting diode, and more particularly to a traffic safety label device using a light emitting diode that can express the contents of the traffic safety sign by a surface light emitting structure using the light of the light emitting diode. will be.

As is well known, traffic safety signs are texts and graphic symbols indicating the contents to be conveyed as signs and signs indicating cautions, regulations, and instructions regarding road traffic. It is important to ensure visibility so that the driver and pedestrians can accurately identify the traffic safety signs.

The contents of general traffic safety signs are marked by reflecting materials reflecting light such as vehicles and street lights or fluorescent materials that fluoresce in 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 a driver's safety driving and cause traffic accidents.

On the other hand, in recent years, even at night and in bad weather, a light source such as a light bulb, a fluorescent lamp, or a light emitting diode is displayed so that drivers and pedestrians can visually easily identify the contents of the traffic safety sign. 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 the power consumption is high and the life is short, frequent replacement is required, and there is an uneconomical problem that requires a large amount of post-management. In the traffic safety signs of the light emitting diodes, an electric light emitting plate that arranges a plurality of light emitting diodes in a dot type is used. However, a large number of expensive light emitting diodes are used, leading to an increase in manufacturing cost. 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 various problems of the prior art as described above, the object of the present invention is a light-emitting light emitting material layer in which the light of the low power, high brightness and semi-permanent light emitting diode is provided in the injection window of the display panel The present invention provides a traffic safety labeling device using a light emitting diode that can greatly improve visibility without regard to perspective angle by a surface light emitting structure expressing the contents of a traffic safety sign.

Another object of the present invention is to effectively prevent the glare of the driver by the structure of the light of the light emitting diode is reflected in the exit window of the display panel by the control of the light control panel, and a sufficient amount of light can be obtained with a small number of light emitting diodes It is to provide a traffic safety sign device using a light emitting diode.

Another object of the present invention is to provide a traffic safety labeling device using a light emitting diode that can reduce the manufacturing cost by a simple structure that can reduce the number of light emitting diodes.
