VERTICAL-TYPE DIRECT RAY DECREASING APPARATUS FOR ADAPTATION TO DIRECT RAY

摘要

PURPOSE: A vertical direct ray decreasing device for adaptability to direct ray is provided to give direct ray adaptation time to a driver by radiating direct ray to a tunnel to overcome brightness difference. CONSTITUTION: A support unit is comprised of a first support stand(12) and a second support stand(12') which are vertically installed on a road. A direct ray blocking unit(14) is comprised of a panel. One end of the panel is installed in the first support stand and the other thereof is installed in the second support stand. A plurality of holes(15) are formed in the direct ray blocking unit. The number of holes increases from the upper side to the lower side of the direct ray blocking unit.
