TS IEC 60050-845
International electrotechnical vocabulary (IEV) - Part 845: Lighting
This part of IEC 60050 gives the general terminology used in lighting, as well as general terms
pertaining to specific applications and associated technologies. This second edition reviews
and complements the previous one. It has the status of a horizontal standard in accordance
with IEC Guide 108, Guidelines for ensuring the coherency of IEC publications – Application of
horizontal standards.
This terminology is consistent with the terminology developed in the other specialized parts of
the IEV.
This horizontal standard is primarily intended for use by technical committees in the preparation
of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
horizontal standards in the preparation of its publications.

About This Item
TS IEC 60050-845 is the International Electrotechnical Vocabulary part that organises the general terminology used in lighting, together with terms relating to specific applications and associated technologies. It provides a shared technical language for lighting engineering so that standards, specifications and technical documents use the same concepts in the same way.
What this lighting vocabulary covers
The scope is broader than the basic notion of illumination. It includes terminology for the lighting domain as a whole, as well as general terms linked to application areas and supporting technologies. In practical engineering terms, lighting vocabulary typically spans sources of light, luminaires, light distribution and control, visual performance, system components and the language used to describe how light is produced, directed and used in real environments. A terminology standard does not prescribe design values; it defines the words and concept relationships that allow those values to be written consistently elsewhere.
Why horizontal terminology matters
The document states that this second edition reviews and complements the previous one and has the status of a horizontal standard in accordance with IEC Guide 108. In that role, it is intended primarily for technical committees when preparing other IEC publications, helping them reuse consistent terminology across related standards. It is also aligned with terminology developed in other specialised parts of the IEV, which supports coherence across electrical engineering subjects and reduces ambiguity between closely related fields.
For users working with lighting standards, design documentation or technical translation, the value of this part lies in concept consistency: it helps distinguish general lighting terms from application-specific language and keeps the vocabulary compatible with the wider IEV structure.
