<p>The present invention relates to a dual radiation traffic sign apparatus, and in particular to a dual radiation traffic sign apparatus in which a self-reflection sheet forms a specific traffic message, and when the light from a vehicle is emitted to a self-reflection sheet, it is reflected by means of a self-reflection sheet, so a specific traffic sign indirectly emits. A plurality of through holes are formed in a self-reflection sheet, so light is emitted through the through holes by means of a lighting unit installed in its interior. When the light from the vehicle is directly emitted to a self-reflection sheet, the light from the lighting unit can be directly emitted through the through holes formed in the self -reflection sheet. Nevertheless a lamp light of a vehicle is directly emitted to a traffic sign apparatus or not, a driver can doubly recognize a traffic sign.</p> |
