According to the definition of the "Design Specifications for City Night Landscape Lighting" (JGJ/T163-2008), landscape lighting refers to the lighting of the night landscape of all outdoor public activities or landscapes except functional lighting such as the stadium venue, construction site and road lighting. The landscape lighting engineering market has become rational since 2020. In the past two years, the popularity of LED landscape lighting in my country has gradually resumed rationality, and the growth rate has slowed down. "Notice of the question" was promulgated, on the other hand, due to the influence of the country's "removing pole", which led to the extension of the period of return on the landscape engineering, the proportion of margin was increased, and the competition was more intense. Big. Despite this, the demand for night scene lighting projects for cultural and creative tourism, night tour economy, and large -scale activities, so the growth rate still maintains a development speed of 10%or more. The epidemic relief in 2020 drives the recovery of the cultural tourism photo market in the second half of the year. In the first half of 2020, the epidemic caused a huge impact on the cultural tourism and night economic field. The demand for cultural tourism lighting markets was sluggish, and engineering projects were greatly affected. At the same time, it has also increased the difficulty of replying to the cultural tourism lighting enterprise. With the relief of the domestic epidemic, the state vigorously promotes the development of the cultural tourism industry and the night economy, and provinces and cities have introduced policies to accelerate the development of night economy and promote consumption growth. The demand for the cultural tourism lighting market is warmed up. In 2020, the size of my country's LED landscape lighting market reached 7.20.09 billion yuan, a decrease of 35% from the same period in 2019. Application scenarios are roughly road landscape lighting, urban complex landscape lighting, garden landscape lighting, building landscape lighting, performance landscape lighting, etc. The main lighting methods include facade light (pan -light) lighting, contour lighting, internal light lighting, silhouette lighting, layered lighting, diverse space stereo lighting, etc. In recent years, large -scale joint media facades have become hot spots. Common LED lamp types include wall lamps, light lamps, line lights, light sources, flexible light bands, buried lamps, underwater lights, other products, etc. According to the statistics of the CSA market research and the China Lighting Electric Industry Association and other related industry organizations, there are only some golden halogen lamps and low -pressure sodium lamps in the field of landscape lighting, and LED products account for more than 80%of landscape lighting sources. The upstream of the industry chain of the landscape lighting industry mainly includes LED lamp beads, electronic components, PCB boards, profiles, wires and other raw materials; the middle reaches of the industry are lighting solutions, control systems, lighting lamp products, other auxiliary materials, labor supply, etc. For landscape lighting engineers, end users are local governments, real estate companies, tourist landscape operating enterprises, other investment entities, etc. The landscape lighting supply chain is generally relatively stable. The amount of landscape lighting engineering involves a large amount of transaction, high brand requirements, stricter supply requirements, short construction period (2-3 months). There is a certain amount of money. In the landscape lighting product link, the business model of "selling for production and ordering with production" is generally adopted, which has high requirements for corporate technology and research and development strength, project experience, large -scale production, human scheduling and guarantee requirements for corporate technology and research and development. In 2020, cultural tourism lighting is becoming more and more specialized, miniaturized, and fine. From the perspective of public bidding, on the one hand, the number and amount of large -scale urban complexions have been significantly reduced. On the other hand, literary tourism becomes a must -have for urban infrastructure construction projects and part of large -scale infrastructure projects. Enterprises are mostly enterprises in the field of municipal construction. For cultural tourism lighting engineering enterprises, there is still a large market space in the future of cultural tourism lighting, but it will become more scattered. With the stretching of the night economy, the local and cultural characteristics, artistic expression, immersive scene -type lighting interpretation of the work market potential, thereby bringing the technical combination of LED and other light sources, intelligent control systems and transmission biography The combination of sensing interaction system, the combination of traditional light shows and water show, combining media architecture show and drone performance, combination of scenic area lighting and real -life performance. The "13th Five-Year Plan" period is a period of explosion in the landscape lighting market. The average growth rate of 2017-2019 reached 24.70%. In the context of the overall decline in China's LED industry in 2019, the growth rate of landscape lighting market is much higher than the industry average. The growth rate (the LED industry has a growth rate of 2.4%, the growth rate of the landscape lighting market is 10%). The introduction of local landscape lighting policy has strongly promoted the prosperity of the local landscape lighting market. Since 2018, more than 10 local governments have introduced landscape/urban lighting related plans and promotion measures, such as Beijing, Shanghai, Shenzhen, Guangzhou, Wuhan, Chengdu, Hangzhou, Taiyuan, Xi'an, Jinan, Qingdao, Dalian and other places. The 2016G20 Summit, the 2017 BRICS Leaders' Conference, the 2018 SCO Summit, and the 70th anniversary of the 2019 founding of the People's Republic of China and the Military Games. National major activities include the Military Games (Hubei), the Erqing Club (Shanxi), the National Day (Beijing), and the bidding projects of Landscape Lighting in Hubei, Shanxi, and Beijing, all of which have entered the top ten of the bidding amount. With the continuous advancement of the urbanization process, the landscape lighting market has blossomed everywhere. Provincial capitals to prefecture -level cities and county -level cities all have investment landscape lighting to promote cultural tourism and enhance the image of the city. According to the data of the National Bureau of Statistics, the average urbanization rate in China at the end of 2020 was 63.89%, and the urbanization rate of urbanization in developed countries is generally more than 80%. China still has huge room for development. In the future, economy and cultural tourism will continue to flourish and become the main driving force for landscape lighting. "Night Tour Economy" uses lights to light up the city night, create distinctive urban landscapes, extend tourism consumption time, create night consumption, and bring new development opportunities for tourist destinations such as cities and attractions. According to the data, the commercial sales of Shanghai at night accounted for 50%of the day, and more than 2/3 of Chongqing's catering turnover was realized at night. Night -tour economic benefits and huge potential. The landscape lighting technology has increased for intelligent control and communication requirements, and the market share of the added value of the added value -based landscape lighting is increased. The profit margin is expected to increase. From 2017 to 2019, the proportion of urban comprehensive lighting projects increased year by year, and the sharp decrease in 2020. On the one hand, because the field of landscape lighting is mainly government investment, it is greatly affected by policies. The comprehensive lighting of large-scale cities from 2017-2019 is driven by large-scale activities such as BRICS Conference, Military Games, National Day, and Er Youth Association. At the end of 2019, the central government's "Notice on the" Performance Project "and" Face Project "issues such as the excessive" landscape lighting project "of the central government" was promulgated to press the slowdown key for large -scale city landscape lighting. The peak of landscape lighting construction in cities above the provincial level was 2017-2018, and since 2019, new projects have begun to show the situation. The largest cities invested in 2020 are prefecture -level cities, counties, townships, and town cities. The peak of urban investment in prefecture -level cities is mainly driven by urban reconstruction and upgrading. County, township, and town -level cities have strongly invested in the process of urbanization. From the perspective of the region, Jiangsu, Guangdong, Zhejiang and other coastal areas, due to the well -developed economy and the projects of the projects, many prefecture -level cities have begun landscape lighting construction. Sichuan, Henan, Guizhou and other central and western provinces strive to build tourism industries, focusing on provincial capital cities, and vigorously invest in urban landscape lighting construction. Since the second half of 2019, the management measures of urban lighting in various places require landscape lighting devices for bridges, water bodies, and new buildings. In the bidding project, landscape lighting has become the "standard" or "subsidiary" of infrastructure projects, independent landscapes, independent landscapes Lighting projects are getting less and less. From the perspective of winning the bidding enterprise, more than 40%of the Landscape Lighting Bid in 2019 is a professional lighting engineering enterprise. The project includes the Wuhan Military Games, the Taiyuan Erqing Club, and the Beijing National Day comprehensive lighting project. By 2020, the landscape, the landscape, In the TOP10 of the Lighting Bidding Enterprise, the proportion of landscape lighting enterprises is only 20%. More and more large municipal engineering enterprises and construction engineering enterprises participate in it. From the 1980s to the present, landscape lighting has gone through four stages. From the 1980s to 2008, it was mainly functional lighting. Lighting lamps were represented by neon lights and high -pressure sodium lamps. With the development of urban integration, the overall planning of urban complexes and urban planning in 2009-2015 drives the entire landscape lighting market to enter a high-speed development period, and the performance methods such as pan-light lighting and outline lighting are increasingly richer. From 2016 to 2019, major events and night tour economy drive landscape lighting into the blowout stage. Intelligent control, media lights, and cultural tourism lights have become the main expression methods. After 2020, landscape lighting is increasingly pursuing high -quality and characteristic development. The lighting design session is becoming more and more important. Lighting engineers and product suppliers need to pass through the design institution before entering the market. Driven by cultural and creative tourism and night tour economy, cultural and creative design will be more in -depth with lighting cross -border integration from lighting, from bright to beauty, from lighting to sound and optoelectronics, from lighting to intelligent control and cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, cultural creativity, and cultural creativity.

When the accumulated UVLED actual solidification application, UV inks often encounter UV ink cannot be quickly solidified, or even react. This is because a single spectrum UVLED cannot effectively achieve the rapid solidification of some UV inks. In the application, it will be found that the use of ultraviolet light sources in different bands can often achieve satisfactory results. For example, the solid light source device of a single UVA band cannot be well solidified by UV inks, but the effect of UVA with UVC will be better. Features of hybrid wavelengths 1.

The changing range of LED lamp bead VF is not considered, resulting in low efficiency of the lamp, and even the price load of the LED light source module in unstable LED light source module. It is generally composed of several LED string of LEDs. quantity. LED's VF changes with temperature changes. Generally, at the constant current, VF becomes lower at high temperature, and VF becomes high at low temperature. Therefore, the working voltage of the LED lamps load at high temperature corresponds to VOL, and the LED lamp load load operating voltage at low temperature corresponds to VOH. When choosing the LED drive, the driver's output voltage range is greater than VOL VOH. If the price of the LED light source module to the large output voltage is lower than VOH, the tolerance of the lamp at low temperature may not reach the actual power. If the selected LED drive to the low voltage is higher than VOL, the drive may be driven at high temperature at high temperature. The output exceeds the scope of the working, the work is unstable, the lamps will flash, etc. But comprehensive cost and efficiency consideration, you cannot blindly pursue the range of the LED driver's ultra -wide output voltage range: because the driver voltage is only in a certain range, the drive efficiency is the highest efficiency. After exceeding the range, efficiency and power factor (PF) will deteriorate. At the same time, the design of the output voltage range of the driver is too wide, which will lead to increased costs and efficiency cannot be optimized. If the power balance and reduction requirements are not considered, the nominal power of the LED drive refers to the data measured by the rated environment and the rated voltage. Considering that different customers will have different applications, most LED drive suppliers will provide a power reduction curve on their own product specifications (common load VS ambient temperature drop curve and load VS input voltage reduction curve)). The red curve indicates that when the price of the LED light source module is input 120VAC, the power reduction curve with the ambient temperature changes. When the ambient temperature is lower than 50 C, the driver allows 100 full loads. When the ambient temperature is as high as 70 C, the driver can only reduce the load to 60%. When the ambient temperature changes between 50-70 C, the drive load of the drive is with the temperature with the temperature with the temperature Rise and linear decline. The blue curve indicates that when the LED driver enters 230VAC or 277VAC, its load has a power reduction curve with the changes in the ambient temperature. The blue curve means that when the LED driver is 55 C, the output power reduction curve with the changes in the input voltage changes. When the input voltage is 140VAC, the load of the driver allows 100 full loads, and as the input voltage is reduced; if the output power remains unchanged, the input current will rise, resulting in the increase in input end loss, the efficiency decreases, the temperature of the device will rise, the individual temperature points may be possible. Excessive standards may even cause devices to fail. Therefore, when the input voltage is less than 140VAC, the output load of the driver is required to be reduced with the input voltage and the linear decrease. After understanding the upper reduction curve and the corresponding requirements, when choosing the price of the LED light source module, you should comprehensively consider and choose according to the actual environmental temperature and input voltage conditions, and leave appropriately to leave the reduction of the reduction of the reduction of the reduction amount.

The ultraviolet rays in the sunlight are divided into three types, of which the wavelength of 100 to 275 nm is ultraviolet rays, which can destroy the DNA of microorganisms (bacteria, viruses, fungi, chlamydia, etc.). Medical ultraviolet light, also known as ultraviolet sterilization lamp (UV light), is actually a low -pressure mercury lamp. Like ordinary sunlight, use low -pressure mercury steam (medical ultraviolet lamp luminous spectrum lines mainly include 254 nm and 185 nm. strip. 254 NM ultraviolet rays to kill bacteria by irradiation of microorganisms. 185 NM ultraviolet rays can turn O2 in the air into O3 (ozone), and ozone itself has a bactericidal effect. According to the newly released "Fast Guidelines for the diagnosis and treatment of new coronary virus pneumonia", 75%alcohol, ether, chloroform, formaldehyde, chlorine -containing disinfectant, peroxycetic acid and ultraviolet rays can be extinguished. Therefore, medical ultraviolet lights are effective for killing viruses. It should be noted that medical and home ultraviolet lights are different in terms of effect. The area area of the house that can effectively disinfect the home ultraviolet light needs to be determined according to the specific instructions. In addition, if ultraviolet lights are used for disinfection in the home, family members must leave the disinfected room during disinfection to avoid ultraviolet rays to people cause damage (ultraviolet rays are risk factors for all kinds of skin cancer). Pay attention to the ventilation of the room after disinfection. *The content of this article is a science of health knowledge.
