Japanese Patent JP2005009114
Kind Code:
A
Abstract:
To provide road guidance indication equipment which prevents the occurrence of discomfort glare, disability glare, etc., and which enables the guidance indication of a boundary on a road even in bad weather.
A floodlight projector 12 which is installed above the boundary 18 on the road 15 emits light toward a road surface. A louver 13 which is arranged between the floodlight projector 12 and the road surface prevents the light applied to the road surface from the floodlight projector 12 from reaching the road surface. This prevents the disability glare, the discomfort glare, etc. from occurring when a person looks into the floodlight projector 12 from below.
