Introduction
the transportation industry is one of the key industries for energy conservation and emissions reduction set by the State Council, the State Council explicitly request to speed up the construction is characterized by low carbon transport system. LED lighting energy saving advantages, market of lamps and lanterns manufacturers have launched used in road, LED tunnel lighting lamps and lanterns. For highway toll station square, the LED light, lighting is a new attempt. We on xiang 'an collection square 1 # high lamp tested LED reformation, the 1 # light, the original eight 1 000 w high pressure sodium lamp replacement for 400 w LED lights, and the 2 # high lamp of unimproved than sexual energy saving measurement. Results show that the LED light, power saving effect is obvious.
1 LED lamp compared with the parameters of high pressure sodium lamp,
the manufacturer to provide the parameters shown in table 1. Feasibility analysis

2. 1 economical comparison
as a collection of the original 4 pole high lamp, every eight 1 000 w high pressure sodium lamp, lamps and lanterns of 30 m high, light time 3 600 h, 10 years to calculate, and the use fee of 400 w LED lights such as table 2.
LED single lamp that prices of lamps and lanterns is about high pressure sodium lamps and lanterns of 4. Initial investment cost is much higher than 5 times, high pressure sodium lamp, but the maintenance cost, and power consumption is much lower than high pressure sodium lamp. From an economic perspective, 10 years 37 can be saved. 260000 yuan. The investment in construction is characterized by low carbon transport system, which can realize the intensive use of resources saving.
2. 2 visual effect is
see from table 1, 400 w leds color rendering index is far higher than 1 000 w high pressure sodium lamp. From the point of the sensory effects to the naked eye, 1 # high lamp 8 400 w LED lamp and 2 # high lights 8 1 000 w high pressure sodium lamp lighting effect is basically the same, but because of the LED light, good color rendering, see things more clearly, so as to improve the driving safety, also for highway toll plaza and build a more comfortable visual environment by collection. From figure 1 and figure 2 photos to compare, leds obviously better than sodium lamp color rendering.
but, LED light source of lamps and lanterns of strong directivity, visual glare slightly higher than the high-pressure sodium lamp.
2. 3 social comparison
leds do not contain harmful elements such as mercury, sodium, won't cause pollution to the environment, accord with strengthening ecological and environmental protection, and realize the developing direction of the green transportation. 3 LED lights with high pressure sodium lamp field intensity of illumination on the measurement results
we entrust a third party LED light field installation and high pressure sodium lamp light intensity of illumination measurement. Installed in the collection and management of internal and external square two 30 m high lighting, square in high lamp installed 8 LED lamp, outside the square installation eight high pressure sodium lamp, all the way to light cloth lamp for circular cloth lamp. The results showed that the average illuminance 8 400 w LED lamp and evenness basic reached eight 1 000 w high pressure sodium lamp and the average illuminance on the evenness.
test area diagram as shown in figure 3 and figure 4.
test data summary in table 3.
4 power saving the measured records
collection after completion of 1 # light, LED by transformation, the energy saving measurement. At 7:00 in the evening light, 5:30 in the morning to turn off the lights. Test method for the two lights from each measurement: 1 # high lamp two LED lights, 2 # high lamp of two high pressure sodium lamp. The installation 1 only single-phase electric meter, base number 0. 5 KWH meter records, for the measured power consumption. Test records are shown in table 8 and table 9.
5 measured economic effect analysis after 28 days of continuous testing, LED lighting power 249. 5 - 0. 5 = 249 ( kWh) ; High pressure sodium lamp 700 power consumption. 8 - 0. 5 = 700. 3 ( kWh) ; 28 days two LED lights to save electricity, 700. 3 - 249 = 451. 3 ( kWh) 367, saves the electricity. 81 yuan. LED lights than 1 lamp high pressure sodium lamp 1 day to save electricity, on average, eight. 1 KWH saving electricity 6. 601 5 yuan. A collection of 32 high pressure sodium lamp replacement for all the LED lights, 10 years can save electricity, 76. 884 yuan ($80000). 6 conclusion
due to the high power LED lighting technology matures, its successful application in highway collection square high lamp, significantly reduce the operation cost of highway administration, saving electricity for highway spending, saving energy for the country.
