More specifically, the present invention relates to a multifunctional LED traffic sign capable of measuring a speed, which is able to install graphite between an LED unit and an embossing frame. In summer, the graphite absorbs heat generated in the LED unit, transfers the heat to the embossing frame, radiates the heat to the outside, and protects the traffic sign from high heat.

In general, road traffic signs installed on roads display various visual information required for the safe movement of vehicles and pedestrians. There are many types of signs, such as indication signs for guiding how to use a road or direction, and caution signs for notifying cautions including road conditions.

Conventional road traffic signs are mainly installed on supports installed on the roadside or on supports installed horizontally at a predetermined height on the upper part of the road. Therefore, it is relatively easy to identify the content of the sign during the day when the surroundings are bright, but it is difficult to identify the content of the sign when it is dark, such as at night, and it is difficult to understand that the sign is installed from a distance, so it did not function properly as a sign.

Accordingly, a separate lighting device was installed to illuminate road traffic signs at night, but since this is a method of recognizing the contents of the sign through the reflected light of the lighting that illuminates the entire surface of the sign, the range of improved identification is limited to a narrow angle. The higher the lighting intensity, the higher the recognition of the sign itself, but there was a problem in that the content discrimination was lowered due to the reflected light.

In order to solve this problem, a road traffic sign in which a plurality of LEDs are arranged in the form of a pattern for displaying predetermined information has been proposed. This has the advantage of improving the visibility of the sign by using the LED, the visible range is wide and the design is clearly displayed even from a long distance.

However, there was a problem in that the circuit board with a plurality of LEDs attached to it did not meet the number of expansions generated according to the outdoor environmental conditions (temperature, rain, snow, etc.) as it was combined with the general signboard embossing frame, causing the circuit board to be damaged.

In addition, in summer, due to the temperature rise generated by the LED, the inside of the road traffic sign is heated due to the change in the direction and lifespan of the LED of the road traffic sign, which causes a breakdown in circuit boards, etc. There was a problem that caused the LED and circuit board failure of road traffic signs and dew condensation.

In addition, even during the daytime, the outdoor illuminance falls depending on the outdoor environmental conditions (temperature, rain, snow, etc.), so that there is a problem that the driver does not recognize the road traffic sign, and an accident may occur.
