Description

Lighting traffic safety sign {Lighting traffic safety sign}

More particularly, the present invention relates to an illumination type traffic safety mark, and more particularly, to a reflective type light guide plate having a reflective sheet, a light guide plate and a PC plate successively joined to an inner surface of an extrusion frame, The panel is fixed to the extrusion frame by a fixing member so as not to be detached after being inserted into the inner groove of the extrusion frame and foreign matter such as rainwater or dust is prevented from flowing from the outside between the panel part and the extrusion frame Since it is a structure in which a waterproof packing is installed, it is thinner than the conventional illumination type traffic safety sign, and it is easy to manufacture and install the light guide plate and the PC plate, so that A / S is easy, cost reduction and manufacturing process are shortened, And it is easy to be separated by an illumination type traffic safety sign, Tong relates to safety signs.

In general, road traffic signs installed on the road indicate various visual information required for safe movement of vehicles and pedestrians, and include regulatory signs that limit the types of vehicles that can be used on the road, Many kinds of signs are used, such as instruction signs that show how to use the roads and directions, and state signs that indicate precautions such as road conditions.

A typical road traffic sign is installed on a support that is installed horizontally at a predetermined height above a strut or a road installed on the road. The conventional road traffic sign has a structure in which a predetermined display content such as a figure or a letter is drawn on a metal plate Therefore, it is difficult to identify the contents of the signboard at night when it is dark, and it is difficult to recognize the signboard even at a long distance, so that it can not function properly as a signboard.

As a result, a separate illuminating device for illuminating the road traffic sign at night is installed. However, since this is a method of recognizing the contents of the signboard through the reflected light of illumination illuminating the entire surface of the signboard, However, as the intensity of illumination increases, the recognition of the signboard itself becomes higher, but there is a problem that the content identification is deteriorated due to reflected light.

In order to solve such a problem, a road traffic sign has been proposed in which a plurality of LEDs are arranged in the form of a figure for displaying predetermined information. This has the advantage that the visibility range that can be identified by the use of the LED is wide, and the design is clearly displayed at a distance, and the identification of the sign improves.

However, the conventional traffic sign has a problem that the lifespan of the temperature-sensitive LED is shortened due to a low heat loss due to the use of a large number of indiscriminate LEDs, power consumption and low heat dissipation.

In addition, a circuit board having a plurality of LEDs is combined with a general signboard frame, and the circuit board is damaged because it does not comply with the number of expansions caused by outdoor environmental conditions (temperature, rain, snow, etc.).
