ON SHENZHEN EXPRESSWAY, AN EXTENSIVE NUMBER OF TUNNELS HAVE BEEN OUTFITTED WITH ENERGY-EFFICIENT LED TUNNEL LIGHTS.

The shenzhen expressway’s led road lighting and led tunnel lighting project, which spans a total of 120 kilometers and encompasses the eastern jihe expressway, the western jihe expressway, the south light-speed, the yanba high-speed, and the da meisha tunnel, is currently the longest and most demanding of the highway projects applying led road lights. The led road light, led tunnel light, and pole light for the six-lane +2 emergency lane have all been installed successfully and are now operational. The average illumination is completely applicable with the criteria of major road lighting, and the lighting effects are well known. Among them, the led tunnel lights replaced the original high-pressure sodium lamps. evaluation of the advantages: It is predicted that the cost of the new led lighting project will be comparable to the cost of the hps and led tunnel lights, and the same tunnel lighting project will be chosen. If high-pressure sodium lamps are used, the tunnel will need 530 100kwh high-pressure sodium light per kilometer, which would result in a total expenditure of 769,000 yuan. In addition, 167,000 yuan will be required for power distribution lines, bringing the total cost to 936,000 yuan. However, if you use led tunnel lights, under the premise of meeting the same standards, you only need 286 led tunnel lights, the total investment is 429,000 yuan, which is a decline of 44 percent compared to those of using high pressure sodium, and the investment in the distribution line is 84,000 yuan, which is a decline of 50 percent, bringing the total investments to 513,000 yuan. addition, the savings in power are 1,017,000 yuan throughout the time of led operation; the expenditures of lighting maintenance are 212,000 yuan, and the whole new lighting project, from the investment to the late operating expenses, cost less than 1.742 million yuan than hps. The use of led tunnel lights on the Shenzhen Expressway is a good illustration of how much more effective they are at reducing energy consumption than hps.
