A linear lighting diffuser is one of the key components in linear luminaires, whose main function is the uniform distribution of light along the fixture and the elimination of dark spots and unwanted shadows. This component, usually installed as a transparent or translucent cover over the lighting profile, is widely used in architectural lighting, interior decoration, and commercial, industrial, and office spaces.
