What are the core functions of led active light-emitting signs? | Led sign
(1) Long-distance visibility
The led active light-emitting sign has super long-distance visibility. Generally, the static visual recognition distance is greater than 250 meters; the dynamic visual recognition distance is greater than 210 meters. Through long-distance visual recognition, the driver can find the traffic language information displayed by the sign, which can win more time for correction of driving behavior and improve the overall traffic safety of the road section.
(2) Wide-angle visibility
The led active luminous sign board does not need to rely on the illumination of the high beam. Through its own luminous effect, it can achieve a large angle of visibility, especially the signs installed on the top of the gantry and on the side of the wider road. The ordinary signs are due to The reflection limitation of the retro-reflected light cone often results in scotopic vision. The led active light-emitting sign can achieve a large viewing angle close to 90 degrees.
(3) Enhance the warning effect
The led active light-emitting sign can use the preset control module to realize the dynamic flashing effect of the light-emitting light source of the sign, enhance the warning effect and easy capture of the sign, and improve the driving safety of the drivers on the road section.
(4) Light penetration in severe weather
The led active light-emitting sign board adopts super light-transmitting LED light-emitting tube. In the harsh traffic environment such as rain, snow, fog, and haze, the light-emitting light source of the sign can penetrate the above-mentioned mask to convey clear traffic language information to the driver. The traffic safety index of the road section.
