Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 31831-2015 "Technical Requirements for LED Indoor Lighting Applications". Compared with GB/T 31831-2015, except for the structure... Aside from structural adjustments and editorial changes, the main technical changes are as follows:

a) The definition of LED light source has been changed (see 3.1,.2015 version 3.1);

b) Added definitions for LED lights, LED luminaires, flicker index, and flicker effect visibility (see Chapter 3);

c) Added requirements for carbon footprint accounting of LED lights and LED lighting fixtures (see 4.4);

d) The specification classification of LED lights and LED luminaires has been changed (see Chapter 5, Chapter 5 of the.2015 edition);

e) Added a specification classification for LED driver power supplies (see 5.3);

f) The performance requirements for LED lights and LED luminaires have been changed (see Chapter 6, Chapter 6 of the.2015 edition);

g) Increased requirements for flicker index and flicker effect visibility of LED lights and LED luminaires (see 6.1.4);

h) Increased requirements for the colorimetric performance of multi-channel luminaires (see 6.1.12);

i) Increased performance requirements for LED driver power supplies (see 6.4);

j) Increased requirements for the color performance of LED luminaires used in elderly care facilities (see A.2);

k) Increased the requirements for the light color performance of LED luminaires used for lighting fresh agricultural products (see A.4.6); Please note that some content in this document may involve patents.

1 Scope

GB/T 31831-2025 is the Chinese national standard covering designing with LED indoors - the illuminance and uniformity by space type, the glare, the colour temperature and rendering, the flicker that most specifications still ignore and that causes headaches and visible stroboscopic effects, and the maintained output over life. It replaces GB/T 31831-2015. It was issued on 31 December 2025 and has been in force since 1 April 2026, replacing GB/T 31831-2015. The document is under the responsibility of the Ministry of Housing and Urban-Rural Development. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the general requirements, specifications, performance requirements, and control requirements for LED indoor lighting in buildings. This document applies to LED lights and LED luminaires used for indoor lighting in buildings and their applications.
