30 w solar street light in rural areas2

Shandong lamps manufacturer of street lamp lighting time every night. 5 hours, the actual lighting for 7 hours (full load h） ； Example 1:1 road LED lights ( If at 7:30 in the evening to open 100% power, the night 11 to 50% power, 100% power again after 4:00 in the morning, at 5:00 am close) Two cases

shandong street lamp factory street lighting time is 9 every night. 5 hours, the actual capacity of lighting for 7 hours, h) ； Example 1: a light emitting diode lamp ( For example, at 7:30 open power 100%, at 11:00 to 50% power, in the morning 4:00 after open 100% of the power supply, closed at 5:00) Example 2:2 the light emitting diode lamp ( Low voltage sodium lamp, energy-saving lamps, energy-saving lamps, etc. ) 。 ) ( For example, two roads at 7:30 and opening up, the first road at 11:00 closed, the second in the morning 4:00 open, closed at 5:00) Five consecutive rainy day lighting requirements to be met. ( 5 days and rainy days the night before the lighting, 6 days) Battery = 5 a times; 7 h times; ( 5 + 1) Day = 5 a time; 42 h = 210 AH in addition, in order to prevent over charge and discharge, the battery is usually charge to about 90%; The remaining emissions of about 5% 20%. Therefore, 210 ah is practical application standard of 70% 85%. In addition, should measure the actual loss according to the different load. Actual working current of the lamps in the street lamp manufacturers in shandong is affected by the constant current source, ballast and line loss, on the basis of the five years may increase 15% About 25%.
