Bilbao is a city in Spain. Located in northern Spain, it is the original settlement of sailors in the Basque Country, famous for exporting iron ore and making ironware. Bilbao is the center of socio-economic development of the Basque Country and the fundamental embodiment of the modernization of the Golfo de Vizcaya. Bilbao's beautiful scenery, with its forests, mountains, beaches and coasts, attracts countless tourists every year for sightseeing and leisure. Modern transport and an extensive road network connect the main cities of the Basque Country, Nebilbao, Vitoria and the surrounding areas of San Sebastián. The Bay of Biscay, 45 kilometers north of Bilbao, is famous for its soft sandy beaches and a surfer's paradise, attracting countless tourists every summer. However, the street lights of the resorts here have been in disrepair for a long time, which has greatly affected the nightlife of tourists, and also brought a lot of inconvenience to local residents. CHZ Spain Branch recommended our all-in-one solar street light to the local municipal agency, and installed several sets of samples first. After nearly a year of testing, the test results were very good, and the local government's permission was reached, and they started the replacement work by our all-in-one solar street lights in tourist villas of a few towns in Biscay.The construction team of CHZ Spain Branch, after preliminary analysis, has formulated a detailed installation plan, which not only protects the integrity of the local ancient buildings, but also does not affect their beauty, and at the same time achieves better lighting effects. Therefore, methods such as lamp pole installation and wall installation were developed. In the hot days, our team worked tirelessly and finally completed the installation of more than ten mountain village street lights within 20 days, and the overall effect was beyond imagination. Next, our team will continue to work hard to complete the installation of solar street lights in other villas to light up the entire Bay of Biscay, thereby attracting more tourists and making greater contributions to Bilbao's tourism industry.
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.
