DETAILS OF LIGHTING DEVICES, OF GENERAL APPLICATION
NOTE
-
1. Groups F21V 1/00-F21V 14/00 cover details of those parts involved in light emission or distribution. Groups F21V 15/00-F21V 31/00 cover details of those parts not so involved.
2. Details of non-electric lighting devices or systems are classified in groups F21V 35/00-F21V 37/00 only if a special adaptation related to the use of a non-electric light source is of interest.

In this subclass have been included only those lighting device details which were considered to be of a kind applicable to the lighting devices of more than one of the subclasses F21L, F21M, F21P, F21Q, F21S. Inventions concerned with details of the kinds provided for are to be classified in this subclass, even though they are only stated to be applied to a device of a single subclass.

The following IPC groups are not used in the CPC system. Subject matter covered by these groups is classified in the following CPC groups:
