The darkness of semiconductor light sources can be regulated , so no matter day or night , LED tunnel light can provide appropriate lighting levels by adjusting the brightness of the light source inside the tunnel . During the day, the tunnel desired brightness is 4.65cd / 2; while at night requires only 0.8cd/m2 brightness. During the day, the average power consumption of lighting inside the tunnel is 70W, while at night requires only 12W of average power consumption to provide enough brightness lighting. Overall, compared with the use of high- intensity discharge lamps lighting system, using Dellux LED tunnel light of Osram can save an average of 10,000 kWh of electricity per year , equivalent to more than 30% reduction in energy consumption.
As experts in tunnel lighting , Dellux has launched intelligent lighting concept for tunnel lighting applications ( such as Schmücketunnel tunnel ) , giving full play to the advantages of LED tunnel light of Golden DRAGON , and with customized electronic circuitry and software , greatly extending the life of LED tunnel lighting systems. Wolfgang Medenwald , vice president of business development in Europe Dellux Technologies company, said : “We installed backup LED in every light fixture, to compensate for the loss of the brightness caused by pollution and the decrease in efficiency, at the same time , we located the currents of all of the LED tunnel light at 85% of its given rated current to achieve greater efficiency and longest durability. despite the environment is extremely harsh inside the tunnel , using our Degradation Compensation Technology of patented technology can ensure the life of LED tunnel light is 5 years at least and achieve the desired lighting levels . ”
For the OSRAM LED lamps Dellux Lighting selected , the power consumption of LED tunnel light reduced by 30% over that of high intensity discharge lamps so that achieve the desired road illumination , the life of LED tunnel light is more than 30,000 hours.Browsing http://www.lead-lighting.com/products/bid32-1.htm，you can know more information about the pretty qualify but affordable LED tunnel light.
