Four national standards in the lighting field were approved and released

According to the “National Standards Announcement of the People’s Republic of China” (No. 7, 2023) issued by the State Administration for Market Regulation and the National Standardization Administration, 4 national standards under the jurisdiction of the National Lighting Appliances Standardization Technical Committee were officially released. The specific list is as follows:

Four national standards in the lighting field were approved and released

GB/T 20147.3-2023

“Colorimetry Part 3: CIE Triple Stimulus Values”

Colorimetry is the basis for chromaticity research and evaluation in optical radiation and related fields, and tristimulus value is the basis for chromaticity. This standard is modified to adopt the international standard ISO/CIE 11664-3:2019, which covers chromaticity-related aspects in the field of lighting. The technical content of the calculation of tristimulus values is elaborated and specified. It is a basic common standard in the field of lighting and a basic universal standard suitable for the lighting industry and its standardization work. The release of the standard will effectively improve the domestic colorimetry standard system, fill the gaps in the system, and provide a basis for colorimetry research and evaluation.

GB/T 20147.4-2023

“Colorimetry Part 4 CIE 1976 L*a*b Color Space”

With the development of artificial intelligence, pattern recognition, remote sensing technology and the expansion of application scenarios, the accuracy of color measurement of objects is getting higher and higher. Wrong measurement results may lead to huge accidents. For example, autonomous driving mainly relies on the reflected image of objects to identify obstacles. This standard provides a basis for standardizing the transmission of values related to the reflected color of objects, improving the accuracy of pattern recognition, standardizing the evaluation and use of colorimeter and other instruments, and plays a good role in promoting the development of related technologies for measuring the reflected color of objects. The release of this standard will provide technical and practical application feedback support for the formulation of relevant national standards and even international standards.

GB/T 20150-2023

“Erythema Benchmark Action Spectrum and Standard Erythema Dose”

The dosimetry problem of skin photobiology is based on the fact that ultraviolet (UV) radiation can cause erythema on human skin, and the degree is closely related to the wavelength: between 250 nm and 400 nm, the degree spans four Magnitude. Therefore, it is believed that the statement that the dose of ultraviolet radiation received by an individual is 1 J·cm-2 (10-4 J·m-2) cannot explain the results of radiation expressed as erythema. If the radiation source is a UV fluorescent lamp, no erythematous reaction will occur except in people with severely abnormal pathological photosensitivity reactions. But the same dose of radiation emitted by an unfiltered mercury arc lamp or daylight-type fluorescent lamp will produce a distinct violet erythema in most fair-skinned people. Therefore, photobiologists have long recognized the need to express this amount of irradiation as an erythema-weighted parameter. In response to the above situations, this standard standardizes the erythema spectral weighting function and defines terms such as standard erythema dose. The revision of the standard will be conducive to technological progress, improve product quality, scientifically standardize the photobiological safety requirements of lighting products, ensure consumers’ safe use of lighting products, and play a role in promoting and promoting the healthy development of the industry.

GB/T 42824-2023

“Emergency lighting”

This standard is equivalent to the international standard ISO 30061 “Emergency lighting”. brightness, uniformity, etc.), the influence of smoke, etc. The release of the standard will help to provide technical feedback support for the revision and formulation of relevant national standards, help the national standards in the field of emergency lighting to be in line with international standards, and help the development of personal safety and the emergency lighting industry.
