What new standards will the LED lighting industry have in 2019?
Lighting technical specifications and product standards are an important part of the development of the lighting industry. With the improvement of LED lighting technology, what changes will be made in lighting technical specifications and product standards? Or the establishment of a new standard? Let's see it together!
Proposed amendments to the Museum Lighting Design Code
According to the “First Batch Revision Plan of 2019” issued by the National Standards Committee, the National Standards Committee decided to propose a revision of the National Standards Plan “Museum Lighting Design Code”. Currently, the project is in the online publicity stage, and the deadline for public consultation is 2019. January 18th.
The National Standards Plan "Museum Lighting Design Code" is under the jurisdiction and reporting by TC289 (National Cultural Relics Protection Standardization Technical Committee). The competent department is the State Administration of Cultural Heritage. The main drafting units are: China Academy of Building Research, China National Museum, Capital Museum, China, Architectural Design and Research Institute.
Since 2009, museums around the world have begun to replace traditional halogen source spotlights with LED lighting, such as the National Museum of Korea, the Louvre Museum in France, and the National Museum of the Netherlands. After replacement, it saves energy compared to the original halogen light source. More than 85%, and LED lighting fixtures do not produce ultraviolet and infrared light like halogen light source fixtures, avoiding damage to museum exhibits and effectively protecting display artifacts. Under the illumination of the halogen lamp, the surface of the oil painting collection will heat up by 1 degree Celsius, which seriously affects the color and preservation life of the painting. LED luminaires can strictly control the output spectrum, use specific illumination for specific works, and do not emit UV damage. Under the LED beam, the picture color is more uniform, and only with a small part of the heat , which is very good for the protection of cultural relics.
In 2010, LED lighting technology was also widely used in the construction and renovation of major museums in China. For example, the Guangdong Provincial Museum, the Palace Museum, the Nanjing Museum New Exhibition Chen Project, the Hebei Museum’s Quyang Stone Carving Museum, and the Zhongshan Ancient Country Museum adopted LED lighting technology. Some LED strip light source module with COB technology and LED controller PWM dimmer and digital control system strictly control the illumination of painting and calligraphy exhibits within 50lx of cultural relic lighting requirements. Some also use intelligent control technology such as DALI system. International museum lighting has always used the International Commission on Illumination's technical report CIE 157:2004 CONTROL OF DAMAGE TO MUSEUM OBJECTS BY OPTICAL RADIAT.

"LED product space color distribution measurement method" implemented this year
According to the Announcement No. 17 of 2018 issued by the State Administration of Small Markets and the National Standardization Technical Committee, the National Radiation Measurement Subcommittee of the National Lighting Standardization Technical Committee is responsible for the implementation of the National Lighting Standardization Technical Committee. GB/T 36979-2018: The LED product space color distribution measurement method was released on December 28, 2018, and the standard will be implemented on July 1, 2019.
In recent years, with the application of LED lighting products in people's lives and production, people have put forward higher and higher requirements for the light quality of LED products. The spatial color consistency of LED products is the influence of LED light quality. An important factor has received widespread attention in the industry. There are many standards or technical specifications in the international and domestic requirements for the spatial color consistency of LED products, and the corresponding measurement methods are very simple, and cannot meet the objectives of laboratory measurement reproducible comparable.
The National Standard for "Measurement Method of Space Color Distribution of LED Products" formulated by the Quality Supervision and Inspection Center of Dongguan City, Guangdong Province, Shanghai Alpha Lighting Equipment Testing Ltd.., Hangzhou EVERFINE Corporation., etc., stipulates white LED products for lighting. The spatial color representation parameters and measurement methods, in order to ensure the consistency and reproducibility of the test, the standard gives a uniform specification for the test environment conditions, measurement equipment and steps and data processing.
Most of the standard project is the research results of the International Commission on Illumination (CIE) Technical Committee TC2-74 "Goniospectroradiometry of optical radiation sources". Professor Pan Jiangen, Chairman of EVERFINE Corporation, who is the chairman of the TC. At present, the international standard drafted by the TC has entered the final stage, while China has taken the lead in international development and issued standards for the color distribution of LED space. To a certain extent, it has also won the first opportunity in the international competition for our products.
NEMA incorporates LEDs into high-altitude road lighting standards
According to foreign media reports, the American Electrical Manufacturers Association (NEMA), headquartered in Rosslyn, Virginia, has published the American National Standard ANSI C136.18-2018 road and area lighting equipment - high pole side mounted luminaires.
It is reported that the American National Standards Institute (ANSI) committee introduced this standard for outdoor lighting, including the physical, operational, maintenance, and light distribution characteristics required for high-altitude road applications under specified conditions. This version updates the references and adds information covering LED technology.
Kevin Fitzmaurice, chairman of the Georgia Power and Lighting Services, the roads and regional Lighting (C136) committee, said the standard describes the features that need to be applied to road lighting, which will be installed on the road. The surface is 65 feet tall or even higher on the high pole.
