The subway tunnel is humid, watery, and poorly ventilated. Subway tunnel lighting fixtures should have the characteristics of waterproof, dustproof, corrosion-resistant, good sealing performance, good heat dissipation, and the protective lighting should reach IP65 (no water can enter when washing the lamps). The lamp has simple structure requirements, convenient installation, and convenient operation when repairing and replacing the light source. The lamp must have good shockproof performance, and can ensure the light source has a high service life under the condition of subway vibration. The light efficiency of the lamp should be greater than 60 lm/W. The lamp should have a certain shading performance to avoid affecting the driver's vision. The light source can be a 3W white LED lamp. When using energy-saving fluorescent light sources, emergency lighting needs to be able to achieve both AC and DC, and instant start, using LED lamps is the best choice. Because when the emergency lighting, the substation sends out 220V DC power; when the normal lighting, the substation sends out 220V AC power. The power of LED lamps is only 3W, which is equivalent to the luminous flux of 60W incandescent lamps. And the life of LED lamps is 50,000 hours, while the life of incandescent lamps is only 1,000 hours. After economic and technical comparison, the use of LED lamps can not only greatly save energy, but also save operation and maintenance costs.
