What’s the comparisons between the LED tunnel light and general lighting
09.09.2013.The lighting electricity consumption accounts for 12% of social consumption in China, the road lighting electricity accounts for about 20% to 30%. As the network planning “79183 of the national highway is implemented,which has ushered in the peak construction of the mountain highway,, both day and night is inseparable from the lighting in order to ensure coherence in the tunnel that is part of road,. The electricity has become a heavy burden of the Highway operation and management of sector in the tunnel. Along with the Global energy increasingly tense, energy-saving design of tunnel lighting is an important part of making impact on the development of the highway
LED tunnel light
There are following comparisons between the LED Tunnel light and general lighting:
1, the black hole effect when entering the tunnel. Because of the large differences in brightness of the Inside and outside the tunnel during the day, in view of outside the long distance the tunnel, the tunnel entrance shows the black hole phenomenon.
2, the dark adaptation after entering the tunnel. When the Car is entering the tunnel from the bright outside, the eyes take some time to see the interior of the tunnel, that is, “to adapt to lag.”
3, low visibility inside the tunnel. As the exhaust fumes of the car can not be quickly dissipated so that the smog is formed, which absorb and scatter the light,resulting in reducing the visibility.
4, the white hole effect (daytime) at the exit of the tunnel. Due to the high brightness outside seen through the exit, which appear to be a bright hole, serious glare. The tunnel lighting is to eliminate above phenomenon and ensure the safe driving. To this end, the tunnel is usually divided into the threshold section, entrance section, transitional section, the basic and outlet sections, each section with different lighting to create a safe and comfortable driving conditions.
Having learned from the characteristics of tunnel lighting, the next step is how to choose a LED tunnel light that can ensure brightness and reduce glare to ensure traffic safety, as well as lower electricity and maintenance and replacement costts. Fortunately,there are a large number of manufacturers specializing in developing and producing LED light over the world, lead lighting is one of them,Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets.

what is the difference between the LED tunnel lights and high pressure sodium
27.08.2013.With the acceleration of urban construction, more and more mountain are connected by the tunnel , we have been concerned about how to choose a good tunnel lighting, as the tunnel is semi-closed environment, we must choose the lamp which can properly light up the tunnel and come through the fog and have the features of the strong waterproof and rustproof ,the high-pressure sodium lamps is currently the most widely used, but with increasing demands on energy saving, plus that the light colour of the high pressure sodium and mercury lamp is narrow, the brightness is low, we begin to turn to LED tunnel lights, so, what is the difference between the LED tunnel lights and high pressure sodium in the end?
1, just from the luminous efficiency, the LED tunnel light is 90lm / w,the sodium light reach 120lm / w;
2, from the performance of through the fog, the golden yellow light of the sodium light can better through the fog, of course, which can also be replaced with warm white LED tunnel light;
3, in view of the initial investment cost, the price of the LED tunnel light is three to four times more than the sodium light;
4, as far as the saving the cost is concerned, taking into account the factors such as the power , LED lights can save more than 60 percent;
5, long life, LED tunnel lights can theoretically reach 50,000 hours or more, but limited by a variety of factors, such as lamps heat dissipation, the life of the power and so on, the life of the sodium lamp can reach 12,000 hours, considering the high cost of maintenance in the tunnel, the LED tunnel lighting is more appropriate;
Generally speaking, 100W LED lighting can completely replace 200W high pressure sodium (the specification of the sodium light is typically 250W), but we should choose the right products from the color temperature, light efficiency, heat dissipation, etc., in addition to a large number of products must be used for the project, we can make a relatively detailed investment plan to contrast,after the initial investment of the product, energy-saving performance and maintenance costs are analyzed. LED tunnel lights is better than the high sodium sodium light.
Shenzhen Lead Opto-Technology Co. Ltd is a professional manufacturer of LED lighting, mainly produce LED High Bay Light, LED Flood Light, LED Panel,LED Ceiling Light etc with OEM&ODM service. As an ISO 9001:2000-certified factory, we can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets.Just browse http://www.lead-lighting.com/products/bid32-1.htm for more information about the LED tunnel light.
