LEDVANCE: Understanding Light Beam Angles
Beam angle is important in lighting design. It determines how light spreads within a space and influences both functionality and atmosphere. By understanding beam angles, you can achieve both adequate coverage and visual appeal. This guide explains why beam angle matters, how it affects different types of lighting, where it is applied, and what to consider when choosing the right one. A light beam angle refers to the spread of light emitted by a luminaire, influencing factors such as intensity, coverage, and glare. Terminology and standards for beam angles vary across industries, with several classification systems in use.
