LED lighting helps build green building lighting

With the continued warming of environmental protection, energy conservation, and low-carbon issues, coupled with the continued shortage of global energy, green lighting has become one of the hottest topics. Incandescent lamps consume too much energy, and energy-saving lamps produce mercury pollution. As one of the fourth generation of new energy sources, LED lighting is favored by government enterprises for its combination of energy saving, environmental protection, and low carbon. Therefore, building green buildings and green new towns naturally cannot miss green building lighting.

LED lighting is part of green building lighting. The green of green buildings does not mean the three-dimensional greening and roof gardens in the general sense, but represents a concept or symbol, meaning that the building is harmless to the environment and can make full use of the natural resources of the environment. A building constructed without destroying the basic ecological balance of the environment can also be called a sustainable building, an ecological building, a return to a natural building, and an energy-saving and environmental-friendly building. Architectural lighting is an indispensable part of green building design. Architectural lighting design must comply with the three major concepts of green building: energy conservation, energy conservation, and return to nature. Architectural lighting is truly green architectural lighting. The LED can directly convert electricity into light. It consumes one-third of the energy of the incandescent lamp to achieve the same luminous efficiency. It can also use smart sensors and microcontrollers to significantly increase equipment maintenance efficiency and reduce management costs. Energy-saving effect and economic benefits. At the same time, the standard LED lighting life is 2 to 3 times that of energy-saving lamps, and does not bring about mercury pollution. LED lighting deserves to be part of green building lighting.

During the 12th Five-Year Plan period, energy conservation, environmental protection, and low-carbon were put on the bill several times. Local governments also attached great importance to the development of energy-saving and environmental protection in various industries. Under the current situation, Shenzhen Guangming New District has built the largest green building demonstration area in China. The construction of the new green city in Guangming New Area is changing with each passing day. The city’s first municipal road with LED lighting system, the underground common trench adopted by the city, the country has been assessed and under construction green With the largest number of buildings and the largest green building demonstration area, these people are very proud of the light. According to Shenzhen Commercial Daily, Shenzhen Guangming New District is the city's first green road using LED lighting system. Compared with ordinary lighting fixtures, LED lighting can save 80,000 yuan per kilometer electricity per year. In the past three years, the newly built roads in Guangming New District have all adopted LED lighting systems. The LED lighting system plays a significant role in power saving, resource conservation and environmental protection in the green building demonstration area. This has brought pilots and exemplary roles to the introduction of LED lighting to green buildings. LED lighting lit green building lighting It is understood that the average energy consumption of shopping mall buildings is 223.08kwh/m2 (1kwh kWh=1 degree), ranking first, and that of hotel and restaurant building ranking at 202.99kwh/m2. In the second place, hospital construction ranks third with 193.87kwh/m2. The rest are government office buildings (183.43kwh/m2), commercial office buildings (103.96kwh/m2), cultural venues (94.62kwh/m2), schools (55.24kwh/m2). With the advent of LED lighting era, LED in addition to deal with the basic energy-saving requirements of shopping malls, hotels and other building energy saving. It is also possible to set the lighting parameters of the LED light source element or the lamp itself according to the user's requirements for the LED, because the user's direct perception of the lighting effect of the lighting is often due to differences in the field environment configuration, decoration, space, and atmosphere. A considerable gap; comfortable and uncomfortable light source performance is not whether the LED lighting has reached the highest lighting output effect, LED lighting industry must be in the development of the product, that is, first predict the possible use of the environment, the use of light sources, so that LED lighting Can play a lighting setting that creates an atmosphere or practical use.

1, large retail energy-saving lighting. The large-scale retail industry has the longest uninterrupted lighting time and the highest electricity costs and operating costs. Therefore, lighting energy consumption is an area of ​​great concern for the industry. Reducing energy consumption is not only the responsibility of the large retail industry for social energy conservation, environmental protection, and low carbon, but also the industry’s performance in reducing operating costs, increasing profits, and increasing competitiveness. LED lighting has the advantages of high luminous efficiency, dimmable, etc. Large retailers can design lighting according to the theme of shopping malls. Through the control of lighting systems and the creation of lighting atmosphere, they bring consumers a comfortable and unforgettable shopping experience and thus increase consumption. The desire to buy again.

In order to allow LED lighting sources to be used in large-scale retailing, China's first retail energy-saving lighting research project started. It is understood that the research project is from the University of Cambridge Center for Architecture and Urban Studies, Tsinghua University School of Architecture and lighting industry leader Sanxiong. Aurora initiated. The research goal is: on the one hand, it will fill the research gap in the energy-saving lighting of retail buildings in China and understand the basic situation of lighting energy consumption in China's retail industry; on the other hand, it will also provide data for the development of energy-saving lighting-related policies and design specifications in China. Support and promote the healthy development of the domestic lighting industry.

2, the hotel energy-saving lighting. The hotel is second only to large energy consumption in shopping malls. Among the hotel lighting costs, the cost of electricity ranks first, followed by labor costs and material costs. The main source of hotel lighting costs is the cost of use, which is the cost of electricity. The initial purchase cost only accounts for 4, so the energy-saving hotels obviously focus on solving the problem of lighting equipment power utilization. Secondly, the light is the soul of the building, through the construction of light to create three-dimensional building, space and level, scenes and atmosphere, focus and details. If hotel lighting can gradually take advantage of LED lighting to create a green, homelike feel, designing a green light experience is not a luxury transformation. On the contrary, this project brings cost savings and also brings customers.

In addition to LED lighting gradually transforming large retail lighting, hotel lighting, but also according to the characteristics of each area, place gradually transform the hospital architectural lighting, government business office lighting, cultural venues architectural lighting, school building lighting and so on. In the near future, LED lighting will light a new era of green architectural lighting.

Green building LED lighting needs to pay attention to the problem At present, although LED lighting sets the advantages of energy saving, low-carbon, environmental protection, and is strongly favored by government enterprises, but due to a variety of environmental factors, LED lighting and many issues need urgent attention. Lack of standards, inadequate supervision of inspections, disorderly and disorderly industries, and opportunistic investment have caused product quality to be uneven. Product quality is uneven, so all green architectural lighting is in the air. Secondly, excessive light pollution caused by LED display advertising has also caused complaints from many citizens. Therefore, LED lighting should enter the era of green lighting as soon as possible, which requires LED designers to be people-oriented. For light parameter settings, brightness, softness, and colorfulness are the body's comfort and no damage.
