Urban lighting is an integral part of urban public facilities, and its quality and level reflect a sign of social progress and modernization. Since the reform and opening up, China's urban lighting has developed rapidly, playing an important role in improving urban functions, improving the urban environment, and improving people's living standards. However, the excessive development of urban lighting has increased the demand and consumption of energy. How to adopt corresponding technologies and management measures to reduce energy consumption is an important issue facing the road lighting in various cities in China. To this end, the Sichuan Provincial Government has increased the promotion of energy conservation in the post-earthquake reconstruction work.
Overview
Reconstruction pays attention to energy-saving LEDs
Relevant statistics show that the total number of urban lighting street lamps in Sichuan Province is 394,994 baht, the annual power consumption is 224.17 million kWh, the night lighting is 242,608 ç›, the night lighting total power is 9616.69 KW, and the total funding is 248,799,300 yuan. These figures are relatively large compared to other provinces and cities across the country. In addition, Sichuan Province lighting street lamps in the sodium lamp 234002 ç›, mercury lamp 16940 ç›, energy-saving lamps 98289 ç›, incandescent lamps 5439 ç›, other lamps number is 40,306 ç›. It can be seen that although the energy-saving street lamps occupy a certain proportion, there is still a large room for improvement.
Reconstruction to promote energy-saving street lamps
Before the disaster in Sichuan Province, the provincial government has repeatedly issued notices on energy conservation work, and urban lighting is also actively seeking energy-saving measures. In February 2008, Chengdu issued the “Implementation Opinions on Doing a Good Job in Energy Conservationâ€, implemented an energy conservation accountability system, and incorporated energy conservation and consumption reduction into the city's target management. The opinion pointed out that Chengdu should increase the proportion of high-efficiency light sources in public facilities and urban road lighting, limit the use of high-pressure mercury lamps, prohibit the use of incandescent lamps, and promote the use of trichromatic fluorescent lamps in hotels, office buildings and residential buildings to limit the use of incandescent lamps. light. In May of the same year, the Sichuan earthquake-stricken cities actively prepared for reconstruction. During the reconstruction process, local governments responded to the national green lighting policy, scientifically planned the severely damaged urban lighting facilities, and paid attention to the use of energy-saving products. In June, an environmentally-friendly and energy-saving street lamp appeared in some towns and towns in Dujiangyan City where electricity supply was unstable. The street lamp was ten meters high and had fan blades and solar panels at the top. This new type of street lamp is a solar lighting system aided by Anhui. It can use wind energy and solar energy to store electricity, and it can also play a role in lighting where electricity is not available. It is understood that there are 20 sets of new types of street lamps that have arrived in the first batch, of which 8 are installed in the resettlement site of the transitional building aided by Anhui Province, and the rest have been shipped to the Aba disaster area for installation.
The first LED street light demonstration road passed the acceptance
At present, the Sichuan provincial government encourages the use of green energy lighting such as solar road lighting and garden lighting, and actively promotes high-pressure sodium lamps, metal halide lamps, semiconductor light-emitting diodes (LEDs), T8, T5 fluorescent lamps, compact fluorescent lamps (CFL), and high-power compact High-efficiency lighting source products such as fluorescent lamps. LEDs are gaining popularity among a wide range of energy-saving products. On October 15, the Sichuan Disaster Reconstruction Investment Briefing was held in the Zhejiang Great Hall of the People. At the meeting, the county government of Sichuan Shehong County and the chairman of Hangzhou Zhongrui Optoelectronics, Zhengming Electrical Appliances Co., Ltd. and Hongyuan Investment signed an investment agreement for the LED West Production Base with a total investment of 300 million yuan. The land will be acquired in Shehong Yinhua Industrial City. 300 acres to establish LED production base in the west. In addition, on October 20th, the first LED light source lighting street lamp demonstration road in Sichuan Province, Shuangliu County's Xiaolong Modern Agricultural Park LED street light demonstration project passed the acceptance. It is understood that the demonstration section is 3 kilometers in length, with a total of 84 è·¯ street lamps, 32 plaza street lights and 10 meters high poles. The total installation cost is 600,000 yuan, with an average of 5,200 yuan per lamp; the initial installation cost savings of sodium street lamps 257,400 yuan, an average of 2,200 yuan per lamp (mainly cable costs); installed LED street lights every 100W, equivalent to the ordinary sodium lamp 250W brightness, lighting for 3 hours a day, can save electricity 19053 degrees throughout the year.

White IDC Connector :IDC connector Automotive Connector is a kind of component that electronic engineering and technical personnel often contact. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The form and structure of automobile connector are changeable. It is mainly composed of four basic structural components: contact, shell (depending on the variety) and insulator.
