Light-active

Describing a substance, process, or organism that is influenced or activated by light. This activation can manifest in various ways, including a change in color, a chemical reaction, growth, or behavior. The term encompasses a wide range of phenomena, from the photosensitivity of certain materials to the phototaxis exhibited by organisms. It often implies a dependence on or response to light, indicating a specific interaction between light and the subject. The light is the trigger for a defined change within the subject.

Light-active meaning with examples

• Certain photographic papers are light-active; they darken when exposed to light, forming an image. Sunlight-activated tanning creams contain ingredients that trigger melanin production on exposure to UV light. Photosynthetic organisms are, of course, light-active, harnessing light energy to convert carbon dioxide and water into sugars. The art installation used light-active paint that changed color when a spotlight shined directly upon the installation, changing the color of the artwork.
• The light-active compound within the algae activated its chloroplasts to generate energy during the day when exposed to sunlight. light-active dyes can be incorporated into fabrics to make them change colors. The new light-active solar panels generate electricity when in direct sunlight. The light-active molecules present within the plant leaves responded to the light, causing photosynthesis.
• The light-active nature of this material makes it suitable for use in solar cells, where light energy is converted into electricity. The light-active component inside of the glasses will darken. The scientists designed a light-active drug that is activated by specific wavelengths of light, providing targeted treatment. The light-active sensors on the remote control allow it to communicate.
• Light-active bacteria utilize light for energy, unlike chemosynthetic bacteria, which use chemical energy. Some light-active crystals change their optical properties when exposed to light, causing the light to change the angle of transmission through the material. light-active pigments in paints can create unique visual effects. light-active components in a smart screen were changed by light.
