Seven Star Mountain Tunnel LED lamp 285 thousand kwh of electricity

The LED energy saving lamp is used in the tunnel.

After replacing the high pressure sodium lamp with LED energy saving lamp, it can save electricity about 285 thousand degrees for a year in the east of the mountain road.

According to the preliminary design and planning, Resort Lake Road seven mountain tunnel needs a 150 Watt lamp, high pressure sodium lamp 236 180 watt HPS 68 lights, 300 Watt HPS 90 450 watt lamp, high pressure sodium lamp 38, in order to make the tunnel entrance and exit lighting inside and achieve the desired lighting effects, the driver in the tunnel by driving to minimize the impact of the.

However, in the construction process, the use of a new type of LED energy-saving lamps, the number of light bulbs and the number of tiles used in the tunnel has been significantly reduced. The project implementation unit, Kunming's science and technology development limited company chairman Ding Jie introduction, the current seven mountain tunnel were used 56 watt LED 236 lamps and 84 watt LED 144 lamps and 112 watt LED 90 lamps, will achieve the desired lighting effects.

In the original design, the total power of high pressure sodium lamp will be 91740 watts, but after the use of LED lights, the total power has dropped to 26544 watts. Ding Jie said: after our monitoring, according to the full power of 24 hours a day lighting calculation, the use of LED lights after the tunnel, can save about 676 degrees a day, a year can save about 246 thousand degrees. If the semi functional lighting calculation, can save about 782 degrees a day, a year can save about 285 thousand degrees. According to the electricity sector in Kunming approved electricity prices to 0.8 yuan per kilowatt hour calculation, the use of LED lights in the annual cost of more than 20 yuan. "
