GB/T 2900 "Electrical Terminology" is divided into several parts: The purpose of developing standards for electrotechnical terminology is to establish standards for electrical engineering, electronics and telecommunications: It provides an accurate, concise and correct definition of the concept and names the terms that express the concept: The formulation of electrical terminology standards is "oriented to "Standardized" aims to help standard writers formulate standards and to help standard users understand and implement standards: Translators of texts (as well as more general technical ones) are also helpful: The purpose of formulating standards for electrical terminology is not to cover all electrical technologies: It refers to all terms used in technical standards, but to develop general terminology for electrical technology: This document is Part 65 of GB/T 2900: This document is normative standards, technical documents, professional manuals, teaching materials, books and periodicals, etc: It is formulated with electrical terminology in lighting and related fields, and can be used by relevant departments such as scientific research, design, production, teaching and publishing in related majors: personnel use: Electrician Terminology Lighting

1 Scope

GB/T 2900.65-2023 is the lighting part of the Chinese electrotechnical vocabulary, and at 123,500 words of translation it is one of the largest terminology documents in the system. It is the Chinese adoption of the IEC and CIE lighting vocabulary, and it defines the whole field: the radiometric and photometric quantities and their units, luminous flux, luminous intensity, illuminance, luminance and the relationships between them; colour, colour temperature, chromaticity, colour rendering and the metrics built on them; vision and the physiology behind the photometric system; lamps and their characteristics by technology, incandescent, discharge, fluorescent and LED; luminaires and their optical, electrical and thermal characteristics; control gear and control systems; lighting design terms for interior, exterior, road, emergency and sports lighting; and measurement. Every other Chinese lighting standard, product or design, uses this vocabulary. For a lamp or luminaire maker, a lighting designer, a laboratory or a translator working on Chinese lighting material, this is the reference.

This document defines the general basics of lighting and optical radiation, human visual and non-visual effects, measurements, products, optical properties of materials, and applications: (such as lighting, therapy, visual signaling and imaging technology): This document applies to lighting and related application technology fields:

Note 1: This entry is numbered 845-01-01 in IEC 60050-845:1987: 02-07: 845-21-002 opticalradiation optical radiation Electromagnetic radiation with a wavelength (845-21-025) located between the transition zone to X-rays (lambda~1nm) and the transition zone to radio waves (lambda~1mm) Shoot (845-21-001):

Note: This entry is numbered 845-01-02 in IEC 60050-845:1987: 845-21-003 visible radiation visibleradiation Optical radiation (845-21-002) capable of directly causing visual sensation (845-22-083):

Note 1: There is no clear limit to the spectral range of visible radiation, because it depends on both the radiant flux (845-21-038) reaching the retina (845-22-001) and Depends on the responsiveness of the observer: Generally, the lower limit is between 360nm~400nm, and the upper limit is between 760nm~830nm:

Note 2: This entry is numbered 845-01-03 in IEC 60050-845:1987: 845-21-004 Infrared radiationinfraredradiation;IRradiation;IRR Optical radiation (845-21-002) with a wavelength (845-21-025) greater than visible radiation (845-21-003):

Note 1: Infrared radiation in the wavelength range of 780nm~1nm is usually subdivided into:

---A band infrared radiation (845-21-005): 780nm~1400nm, or 0:78µm~1:4µm;

---B band infrared radiation (845-21-006): 1:4µm~3:0µm;

---C-band infrared radiation (845-21-007): 3µm~1mm:

Note 2: The precise boundary between "visible radiation" (845-21-003) and "infrared" cannot be defined because light with wavelengths (845-21-025) greater than 780nm can still be
