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.

Scope Notes

Glossary: Light source Light sources The entity (e.g. light bulb, fluorescent tube, gas mantle or combustible charge) that generates light for a lighting device. | Application references: Arrangements of signalling or lighting devices, the mounting or supporting thereof or circuits thereof for vehicles in general
