Spectrum-extended road electric sign, road electric sign control system and traffic information acquisition device using the same

Abstract

The present invention relates to a spectrum-expanded road electric sign, a road electric sign control system, and a traffic information acquisition device using the same. To this end, the spectrum-expanded road electric sign of the present invention comprises: a housing provided with a substrate therein; a visible LED array including a plurality of visible LEDs repeatedly arranged on a substrate to allow various types of traffic information to be visually recognized by a driver; and an infrared LED array including a plurality of infrared LEDs repeatedly arranged adjacent to the respective visible LEDs. As a result, even in the case where the driver's visibility is not sufficiently guaranteed due to adverse weather conditions, infrared light in the non-visible light range is also emitted, making it possible to capture an infrared video by capturing infrared images.
