Abstract

PURPOSE: A traffic sign using an EL lighting is provided to offer a traffic sign being as thin as possible and clear and highly recognizable traffic sign at night by performing a highly recognizable owing to a reflectivity of a high-brightness paper and clearly displaying with a lighting EL supplied by solar cell or commercial power supply. CONSTITUTION: A traffic sign using an EL(Electroluminescence) lighting consists of attaching a high-brightness paper(11) to the front face of an aluminum base plate(10), forming an EL layer(12) to the front face of the high-brightness paper and forming a display film layer(13) to the outermost face. The EL layer is installed to emit a first light in the direction toward high-brightness paper of the front face, and the light reflects from the high-brightness paper and passes through the display film layer and then the content of display is recognized from the outside.

Description

Traffic sign which uses an EL lighting

The present invention relates to a traffic safety sign that is to deliver the contents efficiently during the day as well as at night by using EL (Electroluminescence).

As is well known, signs for traffic safety, various guides / advertisements, etc., are displayed through means of printing or painting, and lighting is provided so that the contents can be easily seen at night.

An example of a specific means of installing lighting is to install a light emitting means such as a light bulb or an LED inside a signboard like a general advertising signboard so that the light passes through a cloth or thin plate (acrylic, etc.) on the front of the display. Alternatively, the lighting device may be installed outside the display panel so that the light is reflected from the display panel so that the contents can be identified.

By the way, there are a number of disadvantages in such a conventional general lighting device, there is a lot of difficulties in manufacturing and installation, short lifespan, because the size and thickness of the lighting device in the form of light bulbs are very large inside, In recent years, even the most widely used LED lighting means could not significantly reduce the thickness, and the manpower and costly problems associated with the installation cost and maintenance still remained.

In addition, even when lighting is installed on the outside of the display panel, a lot of waste due to maintenance is the same, and there are disadvantages such as bringing confusion to the driver's perception by the lighting means and not having a neat appearance. Although it has been developed, this is a problem of manufacturing cost and thick and heavy weight due to the installation of expensive optical fiber is very inconvenient to handle during manufacturing or transportation.

The present invention devised in view of the above problems is possible to implement the signage of the thinnest possible, while also adding the appropriate lighting required at night, the contents to be delivered of the sign is very well communicated and easy for drivers or pedestrians and clearly The purpose is to provide signs that can be recognized.

In order to achieve the above object, the present invention properly constitutes a sign in the order of high brightness paper and EL layer and display film layer or front of EL layer and high brightness paper and display film layer on the front surface of the base plate to reflect the high brightness paper during the day. In addition, it functions as a very discernible sign, and at night, the EL layer lights up with a supply of solar cells or commercial power so that the contents can be clearly displayed, providing a traffic safety sign that is as thin as possible, especially at night. To provide clear and discernible signs.

According to the present invention having such a configuration, it is possible to provide a traffic safety sign that is simple in construction and minimized in volume and thickness by constructing a traffic safety sign using EL which is a very thin light emitting means, especially at night. Even if there is no light for reflection, its own EL lighting can be very discernible.

Accordingly, it is possible to provide traffic safety signs at a low cost and significantly reduce maintenance costs, and it can be said to be a very useful invention, such as the prevention of secondary accidents by means of very thin plate-shaped signs.

Figure 3 is a partially enlarged cross-sectional view showing another embodiment of the present invention

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The sign 1 of the present invention includes a mounting means 2 in the form of a column or a bracket, and a sign 1 is formed on the front of the installation means 2.

Signage (1) constitutes a base plate 10 made of aluminum, attached to the high brightness paper 11 on the front, the EL layer 12 on the front of the high brightness paper (11). The outermost surface constitutes the display film layer 13, which includes display contents for functioning as a sign. That is, the content for display is expressed in figures and colors.

The EL layer 12 is installed to emit primary light toward the high luminance paper 11 so that the light is reflected by the high luminance paper 11 and passes through the EL layer 12 again, and then passes through the display film layer 13. While the display content is recognized from the outside.

In addition, the high brightness paper 11 and the EL layer 12 may change their installation positions. In this case, the EL layer 12 is formed on the front surface of the base plate 10 as shown in FIG. The high brightness paper 11 is formed, and finally, the display film layer 13 is formed. In this case, the EL layer 12 is provided to emit light in the direction of the high brightness paper 11 on the front side.

The EL layer 12 is a solar cell or commercial power is input and the control circuit 20 is connected.

Reference numeral 3 in the drawings is a case.

Looking at the operation of the present invention as follows.

In the daytime, since the sunlight is reflected on the high brightness paper 11, the display content of the display film layer 13 is smoothly displayed without additional illumination. At night, the power is input by the action of the control circuit 20 and the EL layer 12 emits light by the power.

That is, in the embodiment of FIG. 2, the light emitted from the EL layer 12 is reflected by the high brightness paper 11 on the rear surface, and the light is again passed through the EL layer 12 and the display film layer 13.

In addition, in the embodiment of FIG. 3, light emitted from the EL layer 12 is immediately emitted through the high brightness paper 11 and the display film layer 13.

According to the sign of the present invention, EL lighting, which is an efficient lighting device, not only enables a very clear display at night, but also increases the convenience of production and handling due to the feature that can be configured very thinly, Even in a car accident, there is an advantage of minimizing secondary accidents caused by signs.

In addition, the low current consumption is very advantageous for night operation of the sign.
