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.

Street lighting in Red House Community, Nanyuan Street, Fengtai District, Beijing

“The street lights are on tonight, I’m very surprised! Thanks to the street and the community for caring about the people…” Residents living in Feitengjiayuan Community, Red House Community, Nanyuan Street, Fengtai, looked at the street lights and praised the street and community one after another.

Street lighting in Red House Community

A few days ago, the one-week street lighting project of Feitengjiayuan District, Hongfang Community, Yuan Street, Fengtai South District, Beijing, was fully completed. 92 new LED street lamps were all lit up, which solved the problems of old street lamps and insufficient lighting in the community, allowing residents to return home at night. Traveling at home is safe and secure.

It is understood that the Feitengjiayuan community in the Red House Community of Nanyuan Street was built in 2002. The street lights in the community have been used for more than 20 years. There are common problems such as old light poles and light boxes, aging and damaged lines, light bulbs not working or dim lights, etc., which have affected the community. The appearance of the environment also brings safety hazards to residents’ travel. Replacing lighting street lamps has become a major wish of residents. The Red House Community Party Committee gives full play to the role of grassroots party organizations as “outposts” and “probes”, and collects residents’ wishes and demands in a timely manner through the “collection station for public sentiments”.

“The failure of street lights may seem like a trivial matter, but it is actually a major issue related to the safety of residents’ travel.” said Meng Litao, party secretary of the Red House Community in Nanyuan Street.

Under the guidance of the community party committee and party building, the community neighborhood committee, business committee and property “troika” work in the same direction, resonate at the same frequency, and operate on the same axis. They conduct on-site surveys of the community, check the damage to the lamps, and invite professionals to inspect and evaluate. It was found that in addition to the damage to the lamps, some of the wires of the lighting system were aging and could not continue to undertake the lighting function.

Quick response, high-speed solution. After negotiation, the community party committee decided to launch a special fund for the community party organization to serve the masses, and replace all the lighting and street lights in the community to effectively solve the problem of residents’ “urgency, difficulty, and anxiety”.

“The original lamps were various, some had no lampshade, some were hung by a single thread, some were very dark or not bright… The newly replaced LED street lamps had larger wattage and expanded the lighting range; the density of the original street lamps was set not enough, this time a total of 7 street lights were added on the west side of Building 1, Building 2, Building 12, and the north side of Building 13; the middle area of the two-way lane of the community changed from a single-arm street light to a double-arm street light; the central garden was expanded. There are 6 street lights in the surrounding area, taking into account the lighting of the garden and the roads of the community.” According to Meng Litao, Secretary of the Party Committee of the Red House Community in Nanyuan Street, while updating the street lights, the community has adjusted the style, brightness, and location of the lamps. It is hoped that this small renovation project will It can be done in the hearts of residents.

A street lamp illuminates an inch of land, making it convenient for the masses and warming the hearts of the people. In recent years, Nanyuan Sub-district has adhered to the leadership of party building, based on the actual work, focused on the “urgent, difficult and anxious” issues of the masses, and put the “key little things” that the masses are most concerned about, the most direct and realistic, into the hearts of the masses, and solidly promoted the “I am for the masses” We will continue to strengthen the construction of grass-roots service capabilities, actively carry out various forms of convenient service activities, and strive to improve the happiness, security and satisfaction of the masses.

What problems do ordinary people encounter when purchasing LED lamps?

1. LED voltage is low and very safe, misleading people.

The technical personnel of many enterprises do not have a deep and comprehensive understanding of the electrical safety of LED lighting products and driving power supplies. As a result, the electrical safety of many designed and produced LED lighting products completely depends on the safety of the driving power supply, while many supporting The electrical isolation and insulation of the LED drive power supply do not meet the standard requirements. In addition, there is a large amount of publicity that LED is safe at low voltage, which will mislead people to touch the product frequently, resulting in the risk of electric shock being higher than the people subconsciously knowing that its high voltage is dangerous. And don’t dare to touch traditional lighting products casually.

What problems do ordinary people encounter when purchasing LED lamps?

2. LED blue light hazards

The blue light spectrum of blue chip-type white LEDs is more concentrated in the harmful spectrum than fluorescent lamps, including energy-saving lamps, resulting in a spectrum that is about twice as harmful as fluorescent lamps, and the light emitting point is small and the brightness is high. This aspect makes blue light more harmful than other The lights stand out more. However, in theory and long-term product safety certification testing, less than 5% of the most stringent LED desk lamps exceed the RG1 risk requirements, and these lamps only need to be marked with the words “Do not look directly at the light source at close range for a long time” in a prominent position. “Mark and mark the safer distance critical point to remind users that it meets the standard requirements and can be sold and used without any problems. This is much safer than looking directly at the sun for a short period of time. There is no problem with LED lights with frosted covers. And it is not only LEDs that have photobiological safety issues. In fact, some traditional light sources, especially early metal halide lamps, may cause more serious UV damage or even blue light damage.

3. Strobe problem

It should be said that LED lighting products can be the least flicker-free and the most stable (for example, many on the market are equipped with pure DC power supply driving power supplies). Poorly made products can also have serious stroboscopic problems (for example, those without driving power, the AC grid directly supplies power to LED strings or COB-LEDs), but this is also related to the stroboscopic problem of inductively ballasted straight tube fluorescent lamps. Pretty much the same. This does not depend on the LED light source, but on the power supply method and driving power supply that matches it. The same is true for the stroboscopic effects of traditional light source lighting products.

4. Color incompatibility problem

Many people have pointed out that the LED spectrum is discontinuous and not full spectrum, so it feels uncomfortable. But in fact, the LED spectrum is much more continuous and complete than the spectrum of energy-saving lamps that people have used in large quantities for a long time (see the spectrum comparison chart of the two below). However, no one has long said that they are not adaptable or uncomfortable to energy-saving lamps.

Newly installed smart street lights make the streets and alleys of Shilong Town, Dongguan, Guangdong brighter

Recently, citizens who frequently travel to and from Fangzheng Road, Shilong Town, Dongguan City, Guangdong Province have discovered that this road section has become brighter at night. These changes come from the smart street light construction project in Shilong Town.

Newly installed smart street lights make the streets and alleys of Shilong Town, Dongguan, Guangdong brighter

In order to improve the quality of the urban environment and create a good road environment for citizens to travel safely, the Shilong Urban Management Bureau promptly rectified the hidden dangers of lighting “dark areas” according to standards and optimized lighting management. It successively inspected Fangzheng Road, Qinglin Road, Fangyuan Road, Xiangyuan Road, and the renovation and upgrading of old street lamps in Long Road and other sections has solved the problem of insufficient illumination at night caused by aging street lamps in the above-mentioned sections, eliminated the risk of collapse caused by rust and corrosion of light pole brackets, and provided a safe and beautiful way for the general public to travel at night lighting protection.

Starting from July 2021, the independent street light poles, probes, signal lights, signs and other poles on the streets of Shilong Town, Dongguan City have been gradually broken into pieces. The poles that once affected the appearance, blocked the sight, and caused inconvenience to the citizens are gradually being replaced. Turn into a multifunctional smart light pole.

In the past, there were many poles on the streets of Shilong, and the structure, height, color, and size of the poles were inconsistent, which affected the overall landscape of the road. The poles had a single function, and they were unable to meet the new infrastructure needs for mounting 5G micro base stations and other sensing equipment. In response to this situation, Shilong Town proposed a smart light pole construction idea in 2021. It plans to build 1,550 sets of smart light poles within three years, and simultaneously replace related smart light pole and street light power supply cables, and bury 6 to 8 pipelines in advance to provide In the future, it will facilitate the power supply and optical fiber laying required for mounting other smart sensors on smart light poles, avoid repeated excavation of municipal roads, and “addition” to urban quality construction by “subtracting” from roads.

It is understood that smart light poles can realize the integration of traffic sign poles, electric police poles, signal light poles, etc., achieving a pole reduction rate of about 64%. At the same time, 5G base stations, advertising light boxes, environmental meteorology, and video surveillance will also be reserved on the poles, public broadcasting and other equipment mounting interfaces, in the future it can provide citizens with services such as smart transportation, smart municipal administration, smart urban management, smart lighting, smart communities, and 5G base station mounting.

Nowadays, Shilong citizens feel safe when traveling at night, and feel a sense of happiness when looking at the bright roads. At present, Shilong Town has built 18 roads with smart light poles, and a total of 939 smart light poles have been built. The completion of the upgrade of smart street lights has greatly improved the quality of life of Shilong citizens and accelerated the process of refined management in Shilong Town.

With the advent of smart light poles, the independent street light poles, probes, signal lights, signs and other poles that used to be scattered on the roadside and in the sky have been reduced to one piece. The poles that once affected the appearance, blocked the sight, and caused inconvenience to citizens have become multi-functional smart light poles, which have improved the overall environmental quality of the city, introduced fresh blood in smart city construction to Shilong, and truly “subtracted” the roads.

Lighting project in Xinzhou District, Shangrao, Jiangxi

Since September this year, people traveling on the old 320 National Highway in Shaxi Town, Xinzhou District, Shangrao City, Jiangxi Province have discovered that as the afterglow of the setting sun gradually dissipates and the sunset glow fades the last touch of red, the street lights along the national highway light up one by one. The soft and bright lights not only illuminate the way home for passers-by at night, but also warm everyone’s hearts.

Lighting project in Xinzhou District, Shangrao, Jiangxi

It is understood that the X809 Songmaoling to Guomen (Shaxi section) highway was originally the G320 national highway, with a design speed of 80km/h and a speed limit of 60km/h. This section of the road passes through many villages, with densely packed houses on both sides of the road, and also passes through the streets of Shaxi Town. There are many branch roads and streets on both sides of the road, many cross-border vehicles, high speeds, and large lateral traffic interference. The main road has a large volume of mixed traffic, high vehicle speeds, and incomplete warning signs and markings at intersections. There are many pedestrians and vehicular traffic on the horizontal branch road, and local residents have a low awareness of traffic safety. Especially motorcycles and electric vehicles, which suddenly rush out from the horizontal branch road, can easily cause traffic accidents. According to statistics, from 2018 to 2022, there will be more traffic accidents in this area. About 3,000 traffic accidents occurred on this stretch of road. Especially at night, the road lighting is poor, and some irregular drivers do not turn off their high beams when passing through villages, which affects the sight of oncoming vehicles. Occasionally encountering vehicles and pedestrians rushing out of branch roads and alleys, it is easy to cause traffic accidents.

In the theme education, the Shaxi Town Party Committee and Government regard solving the “blind light problem” within their jurisdiction and improving the happiness index and convenience of people’s lives as one of the grassroots party building “Secretary Pilot” action projects, and “quickly work” to connect with the Xinzhou District Transportation Bureau , and organized a professional construction team to light the main road lights. The total investment of the project is 6.49888 million yuan. The project will start in early July 2023 and be completed at the end of September 2023. The construction period is 3 months. 217 street lights have been fully connected and tested. The entire line has been energized and put into use.

Shaxi Town also actively cooperates with the Municipal Traffic Engineering Quality and Safety Supervision and Law Enforcement Squadron, organizes special activities for random inspections of raw material quality, and conducts random inspections and tests on mortar, concrete, cables and other raw materials used in the project. At the same time, the supervision unit was required to conscientiously carry out parallel tests and inspections. It is understood that a total of 12 quality and safety inspections of traffic construction projects were organized during the construction period, with 48 inspectors/time, and 2 quality and safety spot inspection opinion notices and 3 rectification notices were issued, and implement the rectification situation.

As the street lights light up one after another, it not only solves the problem of people traveling at night and eliminates potential safety hazards, but also relieves the “hope” in the hearts of the people, eliminates the “sorrow” around the people, and greatly improves the people’s confidence. A sense of happiness, gain, and security.

“Technical Specifications for Approval of Energy Saving and Carbon Reduction in Architectural Lighting”

Recently, the Energy Safety Branch of Suzhou Security Association organized a project meeting for the “Group Standards for Approval of Technical Specifications for Energy Saving and Carbon Reduction in Architectural Lighting”.

"Technical Specifications for Approval of Energy Saving and Carbon Reduction in Architectural Lighting"

It is reported that the group logo launched a survey in April 2023, and the survey results supported the formulation of the group logo.

The formulation of the “Group Bid for Approval Technical Specifications for Energy Saving and Carbon Reduction in Architectural Lighting” will help more green energy-saving and emission-reduction projects participate in the fierce carbon financial market, and will also be conducive to the promotion and implementation of more proactive market behaviors for energy-saving and emission reduction. Application to help achieve carbon peak and carbon neutrality.

Lighting design case of Chaohongji Group Headquarters Building

The project is located on the central axis of the cultural landscape of Chaozhou Museum. It is adjacent to the Chaoshan Historical and Cultural Expo Center to the east and the inner bay of Shantou to the north, forming an opposite view to the core belt along the Beicheng coast.

Lighting design case of Chaohongji Group Headquarters Building

The project includes a headquarters office building, a business apartment and a commercial podium building, with a total construction area of approximately 71,827 square meters.

Our design ideas are derived from an in-depth understanding and appreciation of architecture. In this lighting design, we pursued the simple and generous aesthetic expression of the building, deeply studied the texture of the building curtain wall, carefully analyzed the changes in every detail, and used the most appropriate light to depict its temperament.

The lighting of the building tower is designed at three levels: the dynamic light of the texture, the power light of the grooves, and the contour light of the form. I hope to use the purest language to show the beauty of architecture.

The building facade adopts vertical linear light, which can better highlight the simple and modern texture characteristics of the building. The linear light in the static state presents a steady and majestic visual effect, like a wise man with both strength and ambition; the linear light in the rhythmic state is like a happy elf, jumping, flashing and flowing, showing a smart and vitality. Kernel.

In the expression of architectural grooves, we pay more attention to details and strive for the accuracy of each light position to show the delicate texture of architectural materials and create unique light and shadow effects.

The design uses a 20° wall washer for illumination, hiding the lamp on one wall close to the interior of the building, and illuminating the walls on both sides through the principle of secondary light reflection, reflecting the sense of space in the building.

Light is an emotional expression of architecture. We are committed to letting the building exude its own unique lighting language through light design, allowing people to feel the power and beauty of the building in the interweaving of light and shadow.
