Views: 15

At present, the country has built and under construction in highway tunnels has reached more than 1000 kilometers, and at the speed of fast development, but the highway tunnel lighting system research starts late in our country, the foundation is bad, compared with foreign production concentration lighting electrical industry, should be far from economies of scale: the domestic use of tunnel lighting light source should satisfy tunnel under the specific environment of photosynthetic efficiency, luminous flux, life, light color and color rendering requirements, at the same time also require in car emissions form smoke have good visibility, to ensure the safety of driving, so, choose a suitable light source, is an important part of the tunnel lighting.


Tunnel lighting status:

1.      Tunnel effect (dark adaptation or light adaptation) is easy to occur due to the sudden change of light brightness, and there are safety risks;

2.      The exhaust dust particles in the tunnel are large, the air quality is poor and the visibility is low;

3.      The lighting time is the longest and the power consumption is large.

4.    Shortened life and high maintenance cost.

Introduction of lighting sources

HID lamp: low color temperature, poor visual effect, oppression, bad environment;

Ordinary strip lamp: there is glare, low initial light efficiency, preheat starting, short life, difficult maintenance;

LED lights: dazzling lights, glare, poor comfort, toxic pollutants.

 

After the transformation of the induction lamp

high luminance (illumination) uniformity makes it easier to eliminate tunnel effects; the induction light is the light source closest to the sunlight in the light source. It is healthy and comfortable to use, reducing the fatigue of drivers and improving driving safety;

the service life is over 60,000 hours, saving the maintenance cost of light source;

energy saving, environmental protection, excellent explosion-proof, safe and reliable, and establish a good environmental image of the city.
