The power distribution system in the subway is very complex, voltage fluctuate frequently. Subway LED lamps have wider operating voltage range and more stable, which can be reached 100-240V and 85-265V.
Subway lighting is in the enclosure space, the working hours of the lamps is very long which is always above 17 hours. The traditional lamps have great light decay working under this environment, but for energy saving LED bulbs, the LED light sources can work about 5000 hours less than 1% light decay.
It would bring huge workload to the subway metro operation if the lamps have to repeatedly maintain. LED panel light have longer life that is more than 50000 hours and can be designed in a easy maintain way, that is why LED lighting become the first choice of subway lighting.
Electromagnetic interference will influence the communication device in the subway, especially near the operational place, therefore, it is very important to avoid electromagnetic interference.
As tunnel traffic, subway’s operation area is full of Wave vibration energy, so the Shockproof of the lamps in the subway is of great importance.
The outer shape of LED lamps have very high design freedom, which can mould the atmosphere in the subway.
