ELECTRIC INCANDESCENT LAMPS (details or apparatus or processes for manufacture applicable to both discharge devices and incandescent lamps H01J; light sources using a combination of incandescent and other types of light generation H01J 61/96, H05B 35/00; circuits therefor H05B)
Definition statement
This subclass covers:
  • Sources of visible, ultra-violet or infra-red radiation consisting of one or more bodies heated to incandescence by electricity, i.e. incandescent lamps, including such lamps for purposes other than general lighting.
  • Details of electric incandescent lamps, including ancillary devices that are structurally part of the lamp such as optical light modifiers or circuit elements.
  • Apparatus or processes adapted to the manufacture, installing, removal or maintenance of incandescent lamps or parts thereof.

Special rules of classification within this subclass

Documents should be classified in all appropriate classes, i. e. multi-aspect classification is used.

If a document concerns embodiments or elements in detail which are covered by several subgroups dependent on a higher hierarchy group, the relevant information is classified in all the respective subgroups.

The higher hierarchy group is to be used

  • If no respective subgroup exists.
  • If the general idea is relevant for the higher hierarchy as well as all the respective subgroups.
Glossary of terms
In this subclass, the following terms (or expressions) are used with the meaning indicated:

Lamp

includes tubes emitting ultra-violet or infra-red light
