Those engaged in sports lighting work must understand the standards of sports lighting, which is the basis. Because sports competitions are the most international, sports lighting also has international characteristics. It is true that there are many kinds of sports lighting, and their classification methods are also diverse. Here are a few briefly for your reference.1) According to domestic and international standardsAs shown in Table 1, it is the sports lighting standard divided by international and domestic.Table 1 Standards divided by international and domestic 2) By sport typeSports lighting standards can also be divided by sport type. For example, as the world's No. 1 sport football, its football field lighting standards are relatively complete and many, and the standard update cycle is relatively short. Here are a few examples:· FIFA "FIFA Lighting Guide 2020", the standard of pitch lighting systems for FIFA competition venues and training grounds,· Requirements and guidelines;· UEFA "UEFA Stadium Lighting Guide 2019";· AFC "AFC Stadium Lighting Guide 2018";· Football field lighting, technical document CIE57 of the International Commission on Illumination;· BOB (2008 Beijing Olympic Games broadcast and television broadcast) Football Lighting for Television.3) My country's sports lighting standardsSince the group standard has just started, this type of standard is in its infancy, so it is not listed for the time being. Table 2 lists some national standards and industry standards related to sports lighting in my country.Table 2 Some national standards and industry standards for sports lighting in my countryTherefore, sports buildings used for different purposes have different standards for sports lighting!
When we enjoy the convenience and comfort brought by modern technology, the earth environment on which we live is being seriously damaged; therefore, energy saving and consumption reduction have become the common will of the whole society. In order to raise the awareness of the general public about energy conservation and consumption reduction, and to achieve the goal of "implementing the double-carbon action and building a beautiful homeland", the state has designated June 15 as the "National Low-Carbon Day", and will be held from June 13 to 19. , identified as "National Energy Conservation Publicity Week".Shanghai CHZ Lighting Co., Ltd.(called CHZ LIGHTING), as a company focusing on green and low-carbon LED lighting technology, has vigorously promoted LED lighting products in recent years to replace traditional lighting methods to achieve the purpose of energy saving and consumption reduction; among them, solar street lights are one of its main products. First, constantly update, improve light efficiency, and realize intelligent management; at present, thousands of solar lighting projects have been completed in domestic and foreign markets, and have won wide acclaim from customers.In February 2022, CHZ LIGHTING participated in the lighting facility project of a section of the S22 provincial highway in Zhejiang Province. A total of 866 sets of IST11-80W integrated solar street lights were provided for the project, which achieved good lighting effects, achieved obvious social benefits, and achieved the effect of low-carbon and energy-saving. IST11 series integrated solar street lights, using LUMILEDS3030 lamp beads and MPPT controller, the maximum light efficiency of the whole light can reach 180LM/W, the color specially designed lens, the light coverage is larger, and the illumination uniformity is good; and UVA control technology, The farthest remote control distance is 30 meters; and the AIOT technology of the Internet of Things can be used to connect all street lights to realize real-time monitoring. For this project, the initial owner has three options; for different schemes, they will bring different benefits to energy conservation and environmental protection for comparison: OptionsAnnual electricityconsumptionAnnualCO2 emissionsAnnualcarbon consumptionAC220V power447,460 kWh446 tonsSave122 tons of carbonSolarpowered447,460 kWhNoCO2 emissionsNocarbon emissionsSolar+IOT313,222 kWhNoCO2 EmissionsNoCarbon EmissionsOur solution is: Solar + Internet of Things. The pole height is 10 meters, and the distance between the poles is 35 meters. Our IST11-80W integrated solar street lights are used, with a color temperature of 5000K, a color rendering index of ≥Ra70, and a light efficiency of 180LM/W.We use coal-burning thermal power generation as a reference to calculate the emission reduction benefits of electricity saving. According to the statistics of experts: for every kilowatt-hour (kWh) of electricity saved, 0.997 kilograms of “carbon dioxide” is reduced accordingly, which is equivalent to 0.272 kilograms of “carbon” reduction. The initial investment of the mains power supply scheme may be slightly lower, but considering the later maintenance and impact on the environment, the solar power supply and solar power + IoT power supply schemes are more feasible. Considering the convenience of lighting debugging and maintenance in the later stage, the project finally adopts the solar energy + Internet of Things solution and the Internet of Things control module, which can realize the following functions:1) You can view the actual and historical data of the solar street lights registered in the system (daily charge capacity, daily discharge capacity, device voltage, device current, device power, etc.);2) The lighting time and brightness of street lamps can be modified remotely;3) Fault reporting and quick maintenance (in case of solar street light failure, an error will be reported in the system, and the specific location and number of the faulty light will be displayed, so that customers can quickly find and repair);4) The IoT control module also takes into account the energy-saving debugging function, and can manually adjust the lighting mode according to the actual use and environmental conditions of customers. Based on various performance comparisons, the owner finally chose our solution and products.After nearly 2 months of intense construction, the project has been installed and put into use; after on-site testing, the average illuminance of the road surface has reached 25LX, and the uniformity has reached 0.4; it can be seen from the weekly data of the Internet of Things background (as shown in the figure below), perfect Realize the transformation and utilization of natural energy, achieve energy conservation and environmental protection and the effective use of natural resources. After the implementation of the project, the lighting effect has been widely praised by the surrounding residents; the energy saving effect and intelligent control have won high praise from the leaders of the local municipal department. CHZ LIGHTING will continue to develop more solar lighting products, practice green and low-carbon commitments, actively promote the use of solar street lights, do a good job in the production, research and development, promotion and publicity of solar street lights, implement the "double carbon" action, and build a beautiful The great purpose of the homeland continues to contribute.

By May, the 2021 annual report and the 2022 first quarter report of the national lighting listed companies have been released.In terms of overall performance, in 2021, major listed companies will gradually return to their pre-epidemic development levels. 77% of the companies will achieve a year-on-year increase in annual revenue, a total of 90 companies; 64 companies will have an increase in net profit, accounting for 55% of the total. ; Gross profit margin increased by 34 companies, accounting for 29%. Among them, in the field of lighting applications, among the 44 companies with A shares/H shares, 36 companies have decreased gross profit margins, accounting for 82%, and the decline is relatively large. The data in the first quarter of 2022 is lower than the same period last year, and all sectors have experienced performance declines to varying degrees, with packaging companies experiencing the most significant decline. The number of A-share listed companies whose performance and net profit declined year-on-year accounted for 46% and 62%, respectively. In the packaging sector, the number of companies with declining profits and revenue accounted for 80% and 90% respectively.The repeated epidemics and the Russian-Ukrainian war have caused changes in the world structure. At the same time, under the influence of factors such as rising raw material prices, shortage of chips, logistics obstruction, exhibition postponement, and real estate entering a downward cycle, the profit margins and delivery of enterprises have been affected to varying degrees. impact, and is difficult to digest in a short period of time. The decline of the overall profitability of enterprises and the difficulty of increasing income and profits have become the norm, which makes most industry practitioners feel anxious and uneasy. At present, China's lighting industry is moving from the LED lighting era to the AIOT intelligent IoT lighting era. The greatest certainty in the information age is uncertainty. Seizing opportunities, finding the essence of things and using them flexibly can benefit from it and even lead the trend. First, the intelligent wave of the fourth industrial revolution has arrived. So far, human society has gone through three industrial revolutions, and is now entering the fourth industrial revolution with intelligence as the core technology and data as the core resource. Before the Industrial Revolution, whether in the East or the West, per capita GDP did not substantially increase for about 2,000 years. However, in the two hundred years after the Industrial Revolution, the global per capita GPD has doubled by 50 times, and the average life expectancy has also doubled.The era of intelligence does not require all enterprises to develop intelligent technology. As long as they make good use of intelligent technology, do a good job in their original industries and continue to promote industry changes, they can become the trendsetters of the times. For example, in the field of unmanned driving, the competition for core technologies is autonomous driving itself, not the artificial intelligence chips (processors) and machine learning algorithms that everyone needs to use.Second, the era of diversified ecological competition has arrived.From the perspective of the evolution stage of the lighting industry, the industry has gone through the product rise stage from 1985 to 1990, the product competition stage from 1991 to 2000, the channel competition stage from 2001 to 2005, the brand competition stage from 2006 to 2010, In the capital competition stage from 2011 to 2020, in 2021, the industry will enter the holographic ecological competition stage of AIOT + optical formula.After the rise of the lighting industry, when many manufacturers "wait for customers to come to the door" in the product competition stage, some enterprises have taken the lead in "going out", skipping "product competition" to "channel competition", and then jumping to "brand competition" "Capital competition", reducing dimensionality and overtaking competitors.The future industry competition is the competition between ecology and ecology. Ecological competition is not necessarily a boxing match to overthrow the opponent, but a tug-of-war match based on who has more people standing behind and the rules market prefers. Enterprises should not only embrace various ecological platforms and choose an ecosystem that is in line with the brand's value proposition to be closely connected, but also establish an ecological competition mindset of openness, sharing, and synergy. The tide of the times is rolling forward, and changes are happening at any time, but no matter how they change, there are some basic rules in the business world that will not change. For example, the user's demand for service and quality, and the enterprise's demand for high-end talents, etc., and the development of the enterprise can only be carried out, but not completed.
