Future development prospect of LED tunnel Light

With the rapid development of road traffic construction in China, the highway tunnel construction scale and the quantity also more and more big, tunnel illumination also appeared such as the energy saving, the security and so on extremely to solve the question, along with the LED light source technology gradually maturely, the domestic illumination profession also carried on the LED in the highway tunnel illumination application research and the application practice.

LED Tunnel Light is a tunnel Light, it is used in LED tunnel lights, workshops, large warehouses, stadiums, metallurgy and all types of plant, construction and other places in large area floodlight lighting, the most suitable for urban landscape, billboards, building façade landscaping lighting.

Then in accordance with the current form of LED tunnel light development prospects, at present, in the tunnel lighting application of the light source, led tunnel Light high pressure sodium Light because of its higher visual light efficiency (can reach

120LM/W) has been massively applied, however, high pressure sodium Light in the tunnel lighting still exist some insurmountable problems, mainly the color rendering is poor and the source power selection range is limited (usually can only choose 250W and 400W), especially in the interior section lighting, the high pressure sodium Light on the one hand has no small power, on the other hand, The glare and strobe light caused by the point-like strong light source are more serious.

In some long tunnels, straight-tube fluorescent Lights have been used because of their higher color rendering and linear illumination, but because of the short life of fluorescent Light, usually only about 8,000 hours, so it often needs to be replaced, which greatly increases the maintenance cost of the tunnel. In addition, the power of the fluorescent Light is small, in the entrance section, the Transition section and the export section, such as the need for higher illumination areas can not meet the requirements. In recent years with the maturity of electrodeless Light technology, LED tunnel Light due to the elimination of the influence of the electrode factor electrodeless fluorescent Light compared to the traditional fluorescent Light has a longer life, can also achieve greater power, which makes electrodeless Light in the tunnel lighting the advantages. However, the luminous surface of electrodeless Light is larger, and the optical efficiency of the luminaire is lower when the optical design is carried out. and LED tunnel lights can be said to be integrated high-pressure sodium Light, straight tube fluorescent Lights and electrodeless Light all the advantages of the current tunnel lighting application is the most ideal light source, its advantages are mainly reflected in the following aspects:

1 high light efficiency. At present, the production of single chip 1W LED light efficiency can reach 100lm/w above, and because it is one-sided light, in the entire lighting system design process, you can achieve very high efficiency of the Light.

2 Long life. LED in reasonable thermal design and power-driven conditions, can have up to 50,000 to 70,000 hours of life, for the 24-hour lighting of the tunnel application, can greatly reduce maintenance costs, and can shorten the payback period.

3 easy to match light. LED light source because the size is very small, one-sided light, the direction of the light is very strong, so it can be very convenient to cooperate with the lens or reflective cup, to achieve the ideal light distribution, not only to improve the use of the entire lighting efficiency, but also to ensure good uniformity.

4 Light design is flexible. LED tunnel light is not only flexible in power design, the use of around 1W led devices, according to the actual illuminance requirements to change the number of LED light source, to achieve the best energy-saving effect, and because the size is very small, the design of the Light shape is also very flexible, can be made into linear Lights to achieve better visual conductivity, Can also be designed into rectangular Lights suitable for higher illuminance requirements of the entry, transition and exit sections.

5 Intelligent dimming control. The use of LED can realize the electrodeless dimming Light, can be combined with the brightness of the hole to dynamically change the brightness of the tunnel lighting, give full play to the technical characteristics of LED tunnel lighting, led tunnel lights to further improve the LED tunnel lighting energy-saving effect, to achieve intelligent tunnel lighting.

Although there is no large-scale application of LED tunnel lights, and the large-scale application of LED tunnel lights also exist a lot of difficulties and challenges, such as LED lighting product standards are not perfect, LED lighting market, the high cost of LED tunnel Lights, these are the LED tunnel Light large-scale market application to bring pressure, But these pressures are inevitable in any new technology during the promotion period. However, with the further development of LED technology, led tunnel lighting and thermoelectric integrated system technology is maturing, LED technology in the field of tunnel lighting applications will certainly be, but also the new future of the half lighting industry.
