Gradual curve signs

Type A, retroreflective signs: Surface uses reflective film material, adhered to an aluminum alloy baseplate. It relies on vehicle headlights to produce reflected light, with a maximum visibility distance on clear nights (with higher-grade reflective film materials) of up to 395 ft.

Type B, panel display active illuminated signs: Surface uses reflective film material (transmittance > 25%), with an LED light source panel placed inside the box structure. Borders and connections are made of aluminum alloy profiles or stainless steel. They do not require vehicle headlights, with a clear nighttime visibility distance of > 660 ft. They can also be clearly visible when visibility is lower than 660 ft due to rain, fog, etc.

Type C, point or line light emission signs: LEDs are embedded on the surface of retroreflective signs, emitting longer wavelengths of light that can be seen from afar, but may affect the visibility of pattern information content.

The active illuminated Curve guidance sign has the characteristics of low power, high brightness and low energy consumption. It is suitable for solar power supply. It is also equipped with a voltage conversion power supply and can be directly connected to the power grid. When the ambient illumination is lower than 100 lux, it automatically turns on the glowing state
