| SECTION F – MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING |
|
| F 21 | LIGHTING (electric aspects or elements, see section H, e.g. electric light sources H01J, H01K, H05B) |
|
| F 21 S | NON-PORTABLE LIGHTING DEVICES OR SYSTEMS THEREOF [1,7] |
|
| Notes |
|
| (1) | This subclass covers devices or systems intended for fixed installation, e.g. vehicle lighting, or for use at a permanent location, e.g. free-standing floor- or table-lamps. [7] |
|
| (2) | This subclass does not cover devices or systems specially adapted for transportation, which are covered by subclass F21L. [7] |
|
| (3) | In this subclass, it is desirable to add the indexing codes of subclasses F21W and F21Y. The indexing codes should be unlinked. [7] |
