12W solar powered led street lamps

12W solar powered led street lamps

NEW! 12W solar powered led street lamps with higher PV power

Improvement comparing with STY series:
1. For same LED power, solar panel power and battery capacity is higher, increasing both charging time and discharging time.
2. Switch material changed to stainless steel, other than previous plastic type, safer and longer service life.
3. The inter contact terminal among all components is changed to waterproof type, increase the waterproof feature, more delicate in workmanship, easier to ship and mount.

Energy saving LED garden/street lights.
Different motion sensor with timer.
Pole optional,easy to install

Specification data for 12W solar powered led street lamps:

Advantage of 12W solar powered led street lamps:

1.Main feature:
1)Integrity design, no cabling, easy to install, various mounting methods (pole or fence)
Pole material could be iron, wood, bamboo, plastic etc, low construction cost.

2)Adopting solar panel as power source, LED as light source, a perfect combination for  energy saving.

3)Adopting high capacity long service life Lithium lron Phosphate Battery, theory life time over 5 years, excellent high temperature performance, long life time can ensure the service life of whole  product.

4)Waterproof structure, safe and reliable.

5)Adopting aluminum alloy as main body material, with excellent rust-proof and corrosion -proof function.
6)With segmented power control function, during late half night, brightness reduce in order to save energy  and increase practicality.

2.Advantage OF Battery powered solar led garden light 12W: 
This product is composed of high efficiency monocrystalline silicone solar panel, 5 years exta long service life lithium battery( same with the drive batteries of hybrid cars), high light efficiency LED lamp and intelligent controller, PIR motion sensor module, theft-resistant mounting bracket.
The most advantage of all in one solar light is easy installation, light-weight, under general normal condition, only 1 or 2 workers using a wrench could finish the installation within 5 minutes.

3.Working principle OF 12W solar powered led street lamps:  
The working principle of all in one solar light is the same with conventional solar light, the only difference is all components-solar panel, LED light, battery and control system are all integrated into one product, using lithium battery to make the whole product more light weight and easy installation.

4. Detail description about battery advantage
1) The most advantage of all in one solar street light is saving construction cost and 
maintenance cost, as well as shipping cost, generally only 1/10 of the cost for conventional solar street light.
2) Another obvious feature of all in one solar street light is extra long service life 5 years, 
adopting global initiative lithium battery management control technology, the total cost for after-sale service and component replacement is significantly reduced comparing with conventional solar light with normal lead-acid battery which requires to be replaced each 2 years.
For all in one solar light with lithium battery, no need to replace or maintain in 5 years, even 
after 5 years, battery requires to be replaced, due to the unique product structure design, the battery could be replaced 
within several minutes without the help of any technical support of engineer.
Normal users could finish the replacement independently.
Long service life lead acid battery is with cycling life 300 times, maximum 500 times.While Lithium iron phosphate power battery, cycling life reaches over 2500 times, under the use of standard charging (5 hours charging), the cycling life could reach 2000 times.

For lead acid battery, the service life is only 1~1.5 years, while for lithium iron phosphate battery using under same condition, theory life could reach 7~8 years.

Overall consideration, the cost performance price of lithium battery is 4 times over lead- 
acid battery. 
Lithium battery comes with feature of high current charging and discharging, with special 
charger, 1.5 current charging 40 seconds could fully charge battery, starting current could reach 2 current, while lead- 
acid battery doesn’t obtain this function.

Lithium iron phosphate power battery comes with higher charging and discharging efficiency, over 90%, while lead acid 
battery is only 80%. The failure of battery starts from second year at rate 6%, while failure of light at rate 2% at rate in 1000 Hours.
