Special rules of classification

Structural combinations of lighting devices with other articles are classified in F21V 33/00, unless specifically provided for elsewhere in this subclass or elsewhere in the CPC.

Details of non-electric lighting devices or systems are classified in groups F21V 35/00 - F21V 37/02 only if a special adaptation related to the use of a non-electric light source is of interest. If there is no such special adaption, classification is made in a relevant general place, e.g. in F21V 21/00 for suspending arrangements

In this subclass, it is desirable to add the indexing codes of subclass F21W in order to indicate the uses or applications of lighting devices, and of F21Y in order to indicate the form of the light sources of lighting devices.
