Compared with high pressure sodium lamp, solar led street lamp can save

Project data traditional high pressure sodium lamp 250 solar 60 w LED street lamp power consumption light source, 250 w, 5 years starting with large current shock processing rectifier series, so the line, damage by 15%; Light 12 hours a day; The actual power consumption 3 a day. KWH of 45, 66 sets of street lamp power 41 for five years. 560000

project data traditional high pressure sodium lamp 250 solar 60 w led street light electricity source for five years to 250 watts, large current when starting shock processing series rectifier, lines and transformer loss is 15%; Lighting for 12 hours a day; The actual power consumption is 3 a day. 45 kilowatt hour, 66 sets of 415600 kilowatt hours of street lamp used for 5 years. Leds lamps using solar power, do not consume electricity payment of electricity per KWH 0 for five years. $8, 66 sets of street lamp of electricity for 33 for five years. 250000 yuan. There is no need to pay electricity maintenance 1 for five years. Replace the secondary light source: 66 times; RMB 100 / set = 66002. Timer, safety devices, such as electronic starter and rectifier parts replaced once every three years, cost is about 66 times. 200 = 13200 yuan; 5 years total maintenance cost: 19800 yuan of the present invention can realize intelligent dimmer, can effectively extend the service life of the system, service life is 6 - Eight years, five years without replacement and maintenance. Xinjiang street lamp

total cost 352300 yuan 0 yuan for five years
