valgusmärgised

Valgusmärgised, also known as luminescent markings or glow-in-the-dark markings, are surfaces or objects treated with a phosphorescent material that absorbs light energy and then slowly releases it as visible light in darkness. This property allows them to become visible without any external light source after being exposed to ambient light.

The phosphorescent material commonly used is a pigment, such as strontium aluminate, which is incorporated into paints, inks, or plastics. These materials are typically activated by exposure to natural or artificial light sources. The longer the exposure and the brighter the light, the more energy the pigment absorbs, resulting in a brighter and longer-lasting glow. The intensity of the glow gradually diminishes over time as the stored energy is depleted.

Valgusmärgised have a wide range of practical applications. In safety, they are used for emergency exit signs, stair nosings, and pathway markings in buildings and tunnels to guide people during power outages or emergencies. They can also be found on road signs, safety equipment, and personal items to enhance visibility in low-light conditions. In the realm of art and design, valgusmärgised are used to create decorative effects, signage, and artistic installations that come alive in the dark. The durability and longevity of the phosphorescent effect depend on the quality of the material and the conditions to which it is exposed.
