Umbrellas that can change color

Date：2023-07-14

A light-sensitive umbrella is an umbrella made of light-sensitive materials that can change color according to changes in ultraviolet intensity. This kind of umbrella usually uses light-sensitive dyes or light-sensitive pigments and has the following working principle:

Photosensitive reaction: When umbrellas are exposed to sunlight or UV rays, light-sensitive dyes or pigments can change color. This is because the molecular structure of the dye or pigment changes under UV irradiation, resulting in a change in color.

Color Change: Depending on design and manufacturing, light-sensitive umbrella cloth can change from one color to another. For example, in sunlight, the color of certain areas may lighten or darken, or transition from one color to another.

Light adjustment: The color-changing effect of light-sensitive umbrella cloth is usually reversible, that is, the color will return to its original state when the light intensity weakens or the umbrella is exposed indoors. Therefore, when the umbrella is removed from sunlight exposure, it will return to its original color.

Light-sensitive umbrellas can reflect the intensity of ultraviolet rays through color changes, reminding people of sun protection and protecting their skin from ultraviolet rays. Plus, they can add some fun and personal touch to a rainy day. However, it should be noted that the discoloration effect of these umbrella fabrics may gradually weaken over time, and the discoloration effect may not be obvious in low-light environments. Likewise, these umbrellas often require special care and use to ensure their color-changing effect is long-lasting.
