Description

{LIGHT EMITTING SIGNBOARD}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a light emitting sign, and more particularly, to a light emitting sign capable of displaying road traffic information while dispersing light emitted from an optical fiber on both sides of a sign.

In general, all roads, such as city roads, national roads, and highways, have road signs that provide road information to drivers.

A road sign is attached to the board with a reflection paper made in the form of letter, number or symbol, and reflects the light of the vehicle through the reflection paper to provide the road information to the driver.
