How to choose tunnel lighting?
Tunnel lighting design steps:
determine the tunnel type → determine the brightness and uniformity of the tunnel → determine the road tunnel type determine the vertical illuminance, higher than the standard → select the appropriate light source and lamps → determine the lighting method, spacing lamps, etc. → calculate the lighting effect to improve the lighting scheme .
Tunnel lighting sources, in addition to meeting the requirements of general road lighting, especially have good light transmission in the smog formed by automobile exhaust. Therefore, in general, high-pressure sodium lamps are mainly used; if it is a short tunnel or an urban tunnel with a small proportion of diesel vehicles, and the smog is relatively small, fluorescent lamps or metal halide lamps with good color rendering performance can be considered. High-pressure sodium lamps or metal halide lamps with large luminous flux are used at the entrance and exit of the tunnel. With the development of LED technology and obvious energy-saving effect, LED tunnel lights will be the best choice for future tunnel lighting.
In order to solve the black hole effect and flicker effect of the tunnel, in addition to a reasonable lighting design, it is more important to choose a reasonable tunnel lighting to ensure the safe passage of vehicles in the tunnel.
The selection characteristics of tunnel lighting should include:
The lamp body is made of special aluminum alloy material, the surface is anodized, with high strength and corrosion resistance;
Reasonable light distribution, high luminous efficiency;
Good sealing performance; can be installed by hanging, ceiling, direct fixing, etc.
