Jiangxi's "Technical Specifications for LED Lighting in Primary and Secondary School Classrooms" was officially released

Recently, the Jiangxi Provincial Market Supervision and Administration Bureau approved the release of the "Technical Specifications for LED Lighting in Primary and Secondary School Classrooms", which stipulates the technical requirements for lamps, classroom lighting requirements, lighting control system requirements, test methods, and installation for LED lighting technology in primary and secondary school classrooms across Jiangxi Province. and maintenance requirements.

It is reported that the standard formulation work began in October 2022. The standard preparation team reviewed and collected national and some provincial and municipal standards and industry literature on LED lighting in primary and secondary school classrooms, and investigated the current situation and status of classroom lighting in primary and secondary schools in Jiangxi Province. The existing problems were identified, the content of the standard was established, and the first draft of the standard was drafted.

After soliciting opinions from relevant enterprises, primary and secondary schools, their competent departments, and testing institutions, the standard preparation team formed a draft after repeated discussions and revisions. Based on the feedback from various departments, the draft for comments was revised and improved after summary and summary, and a draft for review was formed to make the content and form of the technical specifications more scientific and standardized.

During preparation, the standard is based on the actual lighting conditions of primary and secondary school classrooms in Jiangxi Province, formulating scientific and reasonable indicators and technical measures, including technical requirements for lamps and lanterns, classroom lighting quality and energy-saving requirements, lighting control system requirements, Six aspects of test methods, installation and maintenance requirements and acceptance rules are used to determine the measurement indicators of classroom lighting and ensure the integrity of the indicators.

This standard has 9 chapters in total, which are: scope, normative references, terms and definitions, classification, technical requirements for lamps, classroom lighting requirements, lighting control system requirements, test methods, installation and maintenance requirements; and Two normative appendices are published: field test methods, melanin equivalent lux EML measurement and calculation methods. The structure of this standard has been carefully discussed by experts and the compilation team, and determined by consulting a large number of standards and literature materials. The standard structure is rigorous, scientific, practical, and the logic is clear and easy to understand.

At present, this standard is applicable to classrooms of primary and secondary schools that are newly built, expanded, rebuilt and implemented lighting renovations, including ordinary classrooms, reading rooms, laboratories, art classrooms and other classrooms. During the preparation of this standard, 27 highly targeted national standards, 2 industry standards, 4 IEC standards and related documents were cited; the experience of national, industry and local standards was fully used to refine and standardize the technical requirements of this standard.

In addition, the standard also defines the terms of LED lighting technical specifications for classrooms in primary and secondary schools, including: initial value, luminous flux, correlated color temperature (degrees), color tolerance, CIE general color rendering index, CIE special color rendering index, lamps and lanterns Efficacy, working surface, reference plane, illuminance, average illuminance, illuminance uniformity, maintenance factor, glare, uniform glare value, lighting power density, fluctuation depth, flicker, stroboscopic effect, intelligent lighting control system, melanin equivalent lux And visual melanin equivalent daylight (D65) illuminance.

The introduction of this standard can not only ensure that children and adolescents can use qualified lighting fixtures and teaching supplies, protect the visual health of children and adolescents, but also bring authority to lighting enterprises and institutions to participate in the renovation and construction of classroom LED lighting in primary and secondary schools in Jiangxi Province. Technical guidance empowers the high-quality development of the lighting industry in Jiangxi Province and even across the country.
