Light dispersion caps are specialised parts that govern the dispersion and direction of light in lighting systems. Depending on the use, they can be any size and form and are commonly made of glass or plastic. Light dispersion caps work by adjusting the direction and amount of light that comes from a light source. They are frequently employed in situations where uniform light dispersion is sought, including in lighting fixtures for homes and businesses. To reduce glare and regulate light pollution, these caps are also employed in outdoor lighting applications.
