Note(s)
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 [7,2009 01]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, it is desirable to add the indexing codes of subclasses F21W and F21Y
