DETAILS OF LIGHTING DEVICES, OF GENERAL APPLICATION [2015‑01]
NOTE
-
1. Groups F21V 1/00-F21V 14/00 cover aspects related to light emission or distribution. Groups F21V 15/00-F21V 31/00 cover aspects not related to light emission or distribution.

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.

3. In this subclass, it is desirable to add the indexing codes of subclasses F21W and F21Y

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