Design standard for lighting fixtures of rail transit

1. Energy saving and high efficiency: the lighting system accounts for 13% of the total energy consumption of the subway power system, and the average energy consumption of the subway lighting is 26W / m2, which is far higher than the average standard of 6W / m2 in other places of the country.

2. Stable and reliable, long life: in the underground, the density of people is high, the lighting time is long, the intensity is large, the reliability and stability of lamps and lanterns are high, and the service life is long.

3. Lighting is divided into multiple levels: entrance and exit passageway, station hall, platform, carriage and track. Due to natural light, passenger flow density, comfort and other factors, the demand for lighting is different.

4. The design is complex and limited: the subway system includes strong and weak current system, fire protection system, operation system, monitoring system, exhaust system, etc. the lighting design not only needs lighting effect and human feeling, but also needs to take care of other subsystems.

5. Highlight the artistry, culture and urban style: subway environmental decoration highlights the characteristics and style of the city, and lighting design needs to be consistent with the style of environmental decoration to set off.

6. Strong earthquake resistance: there is a certain vibration in the subway carriage, and the platform and station hall will vibrate when the train passes by.
