Brief description of LED tunnel lights

With the rapid development of road traffic construction in China, the scale and quantity of road tunnel construction is also growing, and tunnel lighting has emerged as problems such as energy conservation and safety. With the maturity of LED light source technology, domestic The lighting industry has also carried out research and application practice of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting, using a new generation of light source with high luminous efficiency, good stability and long life will become a demand. And trends.

LED contrast LED with traditional tunnel illumination source

Is a solid state semiconductor device

It can directly convert electricity into light

Compare traditional road tunnel lighting sources (sodium lamps, metal halide lamps, etc.)

LED light source has the following advantages

Low light decay

If the heat dissipation condition is good, the front light 10000h is positive light decay, the first 10000h light decay is 3% to 10%, and the first 50000h is basically 30%, which is far lower than the ordinary road illumination source, and the illumination is more stable.

High color rendering

Generally, the color rendering of LED is about 70~80, which is higher if using three primary color phosphors; the general high pressure sodium lamp is 20~35, and the low pressure sodium lamp is lower, so even if the brightness of traditional light source is higher than LED, the visual effect is poor. For LEDs, "not the brightest, but the clearest to see" should be a direction for the development of LED light source applications.

life:

The life of LEDs is higher than that of general road tunnel illumination sources, and is now generally higher than 50000H.

In addition, LED also has the advantages of high maintenance factor, good safety performance, no stroboscopic and energy saving and environmental protection.

Road tunnel lighting has its characteristics

It is not the same as ordinary road lighting

In design, you need to consider the following points

1. The road surface should have a certain brightness level

2. The tunnel wall should have a certain brightness level

3. Designing factors such as speed, traffic volume, route alignment, etc.

4. Comprehensively determine the level of lighting from aspects such as driving safety and comfort

5. Human visual adaptability, especially at the entrance and exit sections of the tunnel

6. Tunnels also need lighting during the day, and daytime lighting problems are more complicated than nighttime

Applicable environment

Led tunnel lamp housing uses high-strength, tough alloy environmentally friendly materials

Transparent parts are tempered glass, dustproof, waterproof, corrosion resistant and rustproof

Strong resistance to strong impact and impact

Multi-channel anti-vibration structure and high-tech surface coating treatment

Various short-range high-intensity high-frequency vibrations can not affect the luminaire

And can be used in the workshop, roadbed, rail and other high-frequency vibration

Long-term stable operation in a humid, high temperature environment

Good electromagnetic compatibility

Will not cause interference to the transmission network

Compared with traditional sodium lamp lighting, LED tunnel lights save energy and money in the following aspects:

Energy saving performance

1, lighting power consumption is reduced by half;

2. Low heat output compared with the same period of the year;

3. The working current is small, and the long-distance power transmission power line loss is reduced;

Money saving performance

1. Save lighting electricity costs;

2, save daily maintenance costs

3. Saving lamp replacement cost during life

4, save ventilation costs

5, reduce power transmission costs (low current, long distance transmission line loss)

6. When the design stage is considered, the cable diameter can be reduced to reduce the construction cost.
