Description

Sign using LED {A SIGN BOARD HAVING LIGHT EMITTING DIODE}

The present invention relates to a sign using an LED (Light Enitting Diode (LED)), and more particularly to a sign using an LED to enable easy and accurate identification of a sign made of letters, numbers or figures at a long distance.

In general, various traffic signs and road signs are installed on roads such as general roads and highways through which motor vehicles pass to inform drivers of road signs such as direction signs and danger signs to help drivers drive safely. In particular, it is a known fact that a plurality of direction signs or danger signs are already installed in a steep slope or a steep descending part of a mountainous area in order to induce a safe driving by ventilating the surroundings in advance.

Such traffic signs and road signs are marked with specific characters, symbols, shapes, etc., and triangular signs, square signs, circular signs, etc. are mainly used according to their appearance. Traffic signs and road signs should be visible to many people during the day as well as at night.

1A and 1B are diagrams illustrating a traffic sign and a road sign according to the prior art.

1A and 1B, a signal display unit 2 is formed on the surface of a base plate 1 made of a metal plate such as an aluminum plate or a synthetic resin plate. .

The signal display unit 2 displays the contents of the traffic signs or road signs with luminous paint or colored printed reflectors, and these traffic signs or road signs not only decrease the reflectance due to dust or foreign matter over time. While the reflector is oxidized by sunlight, the identification is greatly inferior, and visibility and readability are much lowered because the identification is possible only when the light is received from the headlight of the vehicle at night.

In order to remedy this problem, a number of methods for using a light emitter such as an LED to increase a line of sight in a conventional traffic sign or road sign are disclosed. For example, "Road Safety Signs" of Korean Patent Publication No. 10-2009-0102275, "Road Traffic Signs" of Patent Registration No. 10-719913, and "LED Road Traffic through Solar Power", Utility Model No. 20-2009-0010939.

Arrangement of the partition wall 40 is to be installed not only at the edge but also inside, so as to structurally prevent deformation of the traffic sign.

The side wall 50 allows the signal display unit 20 and the base plate 10 to be integrally formed, and is made of a lightweight material such as an aluminum plate. In addition, when a part of the side wall is exposed to the signal display unit 20, a separate reflector may be attached to the exposed side wall 50a to finish.
