As a public transportation building, the subway cannot be allowed  have problems, because once a problem occurs, it is a big problem. It is estimated that 99.99% of people have not experienced the failure of the normal lighting system of the subway, but just in case of that 0.01%, emergency and evacuation lighting is indispensable. Subway lighting is divided in two parts, functional area lighting and non-functional area lighting. Let's first understand the functional area lighting.

　　One: The lighting of the functional area is divided in the transitional lighting of the entrance and exit, the lighting of the edge of the platform, the lighting of the ticketing and ticket checking area.

　　1. Transitional lighting scheme for entrances and exits

　　Have you ever been driving in a tunnel or taking an underground passage?

　　In the daytime, due  the strong contrast between the high brightness of the environment and the low brightness of the tunnel, and also due  the visual persistence of the driver's eyes on the bright environment, an under-lit tunnel entrance will cause people  have a "black hole effect" and the hole cannot be seen. Any details inside. Therefore, at the entrance, the visual problem of the car in the approaching section should be solved.

　　Figure: The human eye will have a process of adapting  changes in light and shade. From light  dark, the process of adapting will be relatively long. Therefore, there should be no o strong contrast between light and dark, and transitional lighting should be used.

　　Special attention should be paid  this human physiological facr in subway entrance and exit halls, stairs and escalars. When you walk in during the day and go out at night, you can't suddenly look dark.

　　Picture: The entrance of the subway station that needs  pay attention  the transitional lighting. It also takes a while  get used  when you walk in. If you go in with stairs and escalars (usually), there may be safety hazards when there is a lot of people during peak hours.

　　Therefore, the national standard emphasizes this in particular:

　　Transitional lighting standards

　　1. Transition lighting should be provided at the entrances and exits of urban rail transit stations, double-deck ground stations and elevated stations during daytime from platform  station hall stairs.

　　2. Transition lighting should give priority  the use of natural light transition; when natural light transition cannot meet the requirements, artificial lighting transition should be added.

　　3. The brightness changes inside and outside the station entrance and exit during the day should be 1:10~1:15, and the brightness changes inside and outside the entrance and exit at night should be 2:1~4:1. The brightness changes from the platform  the hall of double-deck ground stations and elevated stations during the day are the same as the entrances and exits.

　　4. The calculation of urban rail transit transition lighting is determined by the method in the following table.

　　5. Platform edge lighting scheme

　　The edge of the platform is really a very dangerous place, especially considering the current rush of people in the subway station during rush hours. So now many subway stations have added isolation doors. Lights also play a very important role in warning and guidance in this area.

　　6. Lighting scheme for ticket sales and check-in areas

　　The two areas of ticket sales and check-in are the areas where the illuminance requirements of the entire subway station space are relatively high, and they are required  reach the same illuminance level as a general office: 300lx on the counterp.

　　The panel lights produced by  Lighting have been widely used in subway station lighting

　　Two: Non-functional area lighting scheme:

　　Except for the station hall platform, there are some places in the subway that we can't go , such as the subway tunnel section. The subway tunnel is a non-functional lighting area. The subway tunnel lighting is used for basic lighting for maintenance personnel and for personnel  escape and guide lighting in emergencies.

　　Figure: Recommended value of line lighting illuminance

　　Picture: The subway tunnel lighting of Beijing Metro Line 8 adopts the separate layout of normal lighting and emergency lighting.

　　Picture: Tianjin Metro Line 3 subway line tunnel lighting, the track plane maintains illuminance greater than 5lx at night, and the uniform glare value is less than 22, which meets national standards.

　　In such places with seldom crowded and poor conditions, in addition  meeting the requirements of moisture-proof, dust-proof and shock-proof, the selection of lamps must also choose special tunnel and road lighting fixtures with special light distribution (reasonable light distribution, anti-glare).
