F21V FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR
Description
F21V covers functional features, design details, and structural adaptations of lighting devices and systems that do not fit into more specific lighting classifications. This includes reflectors, diffusers, lenses, heat management components, mounting systems, and controls integrated into lighting fixtures or lamps. The class also encompasses combinations where lighting devices are structurally integrated with non-lighting articles (such as furniture, vehicles, or building elements) without constituting a separate functional invention. F21V serves as a residual category for lighting device improvements and hybrid designs that fall outside the scope of dedicated classes for specific light sources (F21K), lamp types (F21S), or specialized lighting applications.
