¿Qué es la señalización vial que brilla en la oscuridad?

the concept of Glow in the dark Road Markings gained heightened attention following an article from BBC News, catching public interest in this innovative safety feature. Glow in the dark road markings come in various forms, primarily solvent-based paint, water-based paints, and thermoplastic paint. Solvent-based paints are chosen for outdoor road due to their durability and strong adhension. Water-based paints, known for their beneficios ecológicos, are equally popular in some countries. Thermoplastic paints represent another excellent choice with its weather and ware resistant , allowing for the fusion of glow in the dark pigments with thermoplastic materials.

Por la noche, la visibilidad disminuye y determinadas zonas, como las curvas cerradas y los pasos de peatones, se convierten en puntos especialmente peligrosos para los accidentes. Muchas ciudades han intentado hacer que las noches sean más seguras instalando más farolas, mejorando las marcas viales y mejorando los semáforos, pero estas mejoras no siempre llegan a todas las áreas. Donde hay falta de iluminación, los accidentes son mucho más comunes; de hecho, Más del 40% de los accidentes ocurren en áreas con poca iluminación.

Las marcas viales luminosas sirven principalmente como advertencias visuales en lugar de iluminar caminos como la iluminación tradicional. Estas marcas utilizan materiales fotoluminiscentes que absorben la luz durante el día y emit a pale yellow-green phosphorescence at night. Este suave brillo es especialmente useful in darkness for sidewalks, sharp curves, and other high-accident areas, enhancing safety by providing visual signals.

Charged by natural light during the day, these photoluminescent materials ensure that even in dark areas , they Proporcionar un importante beneficio de seguridad desde la noche hasta la medianoche.. The phosphorescence light is a little weak, but still workable. This makes them an ideal solution for enhancing road safety in different settings, particularly where electrical solutions are impractical.

There are various glow paints available on the market. When selecting one, there are three key indicators to consider, which include color, glow powder brightness level, and powder dosage. For road markings, yellow-green color is the best choice because its unique chemical properties provide the highest brightness and the longest afterglow time, which are closely related to the safety attributes of road markings. Higher brightness powder is suggested since in the evening the outdoor is not extremely dark due to moon light. Higher one can present better glow performance. The dosage of glow powder is also important. Road markings usually require a 20%-40% ratio. Lower dosage will result in lower brightness and shorter afterglow. Conversely, paints with a higher dosage have better glow performance.

You might have seen some pictures on the Internet that the glow in the dark lines seem to light up faces just like regular electric lights. It’s got a lot of folks excited about using that glow in the dark paint on roads. But here’s the thing – in real life it’s not quite like that. The glow in the dark paint actually gives off this yellow-green glow very softly, kind of like phosphorescence. You can see it outdoors from evening till midnight, but it’s pretty subtle. When you snap a pic with your phone or camera, though, the auto exposure makes it look way brighter than it actually is. That can throw off folks who aren’t familiar with how it works.
Our field tests have found that the glow in the dark marker line remains visible until midnight only in complete darkness without any electric light around. It can only provide guidance to pedestrians when there is no influence from headlights, street lights and other light sources. Therefore, glow road marking is more suitable for roads in rural areas, suburbs, or areas without electricity facilities, or in places where public lighting is turned off at night. In such situations, glow road marking will have the greatest impact in rural areas and suburbs, providing a glowing guide for cyclists and walking people.
