With high power LED in general are generally used in decorative lighting and lighting, power LED drivers are more and more important. Road lighting will be the possibility of using high power LED lighting. Road lighting is the longest and largest energy consumption lamps, street lamps with led flood lights will greatly reduce the city's electricity shortage, saving energy.
Due to street lamps are cross-line, using the LED manufacturing only made one side light, but just the bulb SI Cho is location, does not affect the lighting effects. Street lamps 20W of power, high power 30W,40W,50W LED manufacturing, long service life, maintenance-free. Due to the small LED low power consumption, low voltage, current, installation section of the cable to the appropriate reduced, saving installation costs. A comprehensive road lighting system consists of a light source, cable, and power supply system to form.
A comparison of street lamps, blue led strip and traditional
Assumptions a city has three segment road length respectively for 3 km, and 5 km, and 10 km, laying street lamps to each across 30.1-meter light, each edge a light calculation, this three segment road by needed of street lamps new definitions today, respectively for 202 light, and 333 light, and 666 light, and traditional street lamps to power for 250W of high pressure sodium for quasi, LED shot lamp to power for 50W for quasi for comparison!
Is priced at $ 1000/traditional street lamps, led panel for $ 3,000/m or more, three lengths of road required laying traditional street lamps Lighting costs are: $ 202*1000=202000, $ 333*1000=333000, $ 666*1000=666000, laying of LED spotlights three lengths of road lighting costs are as follows: 202*3000=606000,333*3000=999000,666* 2000=1998000 (table 1)

Second, the LED lights and comparison of the cost of traditional street light cables
We to analysis three segment length of road two species light laying cable of cost, 3 km road traditional street lamps main route cable load flow I=P/U=202*250/220=230A, it needed cross cut area for 60mm2 of copper core cable, its price for 120 Yuan/m, is its cable cost for 120*3000=36 million Yuan, LED shot lamp route cable load flow 1=P/U=202*50/220=44A, it needed cross cut area for 10mm2 of copper core cable , It required cross section is the 12mm2 of copper cable, is priced at $ 12/m, cable costs of 12*3000=3.6 million Yuan, 5 km road trunk cables load-flow I=P/U=333*250/220=377A traditional street lamps, it required cross section is the 90mm2 of copper cable, price is $ 180/m, cable costs 980*5
