ANTI-DEW ROAD SIGN USING INSULATION BOARD STRUCTURE

摘要

The present invention relates to a road sign having a dew condensation prevention function for preventing dew condensation on the surface of a front display member caused by the temperature difference between night and day and the disablement of retro-reflection caused by the dew condensation by forming an insulation board between a metal base plate and the front display member where road information is displayed. According to the present invention, the road sign prevents dew condensation caused by the temperature difference between night and day by forming the insulation board thereon and reduces manufacturing costs in comparison with an existing road sign by enabling the easy manufacture and installation thereof.
