Lighting fixtures adhering to dark sky principles minimize light pollution. These specialized designs direct illumination downwards, reducing glare and upward scattering of light. An example is a shielded fixture that only allows light to shine below the horizontal plane, ensuring illumination is concentrated on the intended target area.
Employing such technology is crucial for preserving the natural night environment. This approach reduces energy waste, benefits nocturnal wildlife, and enhances astronomical observation. Historically, concerns about light pollution’s adverse effects on ecosystems and human health have driven the development and adoption of these technologies.
