LED lighting "underground money scene"

In recent years, with the rapid economic development, road congestion has become increasingly serious, and major cities have successively built underground subways to relieve traffic congestion. At the Guangzhou Asian Games and the Shenzhen Universiade, LED green lighting shined into the subway car quietly. LED lighting has naturally become a beautiful landscape of the subway. Jiuzhou Optoelectronics, Shifu Lighting, Xinli Light Source, and Shenzhen Optical Optoelectronics all compete for the LED lighting market.

The rapid development of LED lighting technology and the in-depth implementation of China's energy-saving and emission-reduction policies have led LED light sources to begin to be used in road lighting and subway lighting. In recent years, there have been hundreds of road and tunnel lighting companies that have developed and produced white LEDs as light sources, and subway lines using LEDs as lighting sources have also gradually increased.

LED subway lighting has a significant advantage

Energy-saving, high-efficiency, reliable, strong earthquake resistance, suitable for subway operation environment

As the subway runs underground all the year round, there are high requirements for lighting. It not only requires energy saving, high brightness, long life, but also must ensure uninterrupted lighting. However, common incandescent lamps, fluorescent lamps, high-pressure sodium lamps and the like have certain defects, and some inevitable lighting failures may occur.

In contrast, LED has the characteristics of environmental protection, energy saving, long life, high luminous efficiency, and no radiation, extending its service life and greatly reducing energy consumption. Moreover, the LED's strong earthquake resistance is very suitable for the subway operation environment, and can be replaced within six or seven years. The LED lamp energy efficiency is nearly 50% higher than the ordinary fluorescent lamp.

Therefore, LED has become the best green lighting fixture. The use of LED lights at subway stations can not only save a lot of electricity, but also save a lot of maintenance costs. At the same time, it also ensures the quality of lighting. For the problems existing in the subway lighting system, LEDs provide a subway lighting solution with novel structure, low cost, long service life, good power saving effect, and high reliability.

According to expert estimates, although LED lamps are expensive, they are equivalent to 50 times that of ordinary fluorescent lamps. The total cost of a train reconstruction is as high as 50,000 yuan, but the saved electricity and maintenance costs can recover costs in almost three years, so it is expected to be promoted in large scale in the Beijing subway. It is understood that ED, also known as semiconductor lighting, is a new generation of lighting technology that is different from ordinary energy-saving lamps. In the G432 train that is being tested, all 168 fluorescent lamps in the compartment will be replaced with LED lights. Compared with the price of five or six yuan per fluorescent lamp, the newly-replaced LED lighting market price is as high as 300 yuan. The current test project belongs to the national "863" scientific and technological research content and is provided by the manufacturer for free.
