Solar LED Street Light is the future.It has more advantage than other light.It combine solar with the LED light.
Solar LED Street light
Product information
Our product has four parts:
1.Solar panel(Foothold)
2.Control box(Controller,Lead-acid batteries)
3.Light pole.(Galvanized)
4.LED lamp.(Power:20W)
We can product the solar street light accorading to our customer's design.Now we will give you the example(Solar LED SL 007)to explain our design theroy.
1.Solar Lead-acid batteries
1.LED light Power Voltage:12V
2.LED light Wattage:20W
3.LED light Electric Current:1.67A
4.Battery Discharge time(Actual):Generally the discharge time is 12Hrs(6:00PM-6:00AM) .But we can use the controller to save the power .So the time can be 8Hrs.
5.Continuous working time(Rainy days):(5+1)Days
So the Battery Capacity:=1.67A*8Hrs*6Days=80AH
But we shall remain 20% of the battery capacity and plus 5% depletion from the working.
Then the finally Battery Capacity:=(80AH/80%)*105%=105AH
The Battery Type :Lead-acid batteries12V/105AH
2.Solar Panel
1.Solar panel (Vm):17.4V
2.Effective illumination(Battery Charging time):4Hrs
3.Reserved:20%
4.Electric Current
5.Battery Discharge time(Actual):8Hrs
So WP/17.4V=(1.67A*8Hrs*120%)/4Hrs,
WP=70W
6.Actual Loss:<5%
The Finally WP=70W*105%=74W
7.Solar Panel Power(WP):12V/74W
And we can product other solar LED street light by this theroy.
Other Product Specifications(SL 001 DC12/24 20W):
1.Luminous Flux(Lm):1600-2000

3.Lamp Lifespan(Hrs):50000
4.Ingress Protection:IP65
5.Operating Temperature Range(°C):-40~50
6.Humidity(RH):20%-90%
7.Max.Cover Temp(°C):<50
8.Avg.Illumination(Lux):16~24
