Features of SRS Solar Street light
Intelligent Digital Controller
 Self-developed LED SFC intelligent module(power consumption0.0625W ) replace regular analogue LED constant current driver which saves 15-20% of system power.
With patented SFC control technology, combined with human eyes vision retention effect(25 frames/second) power consumption could save 50%power compared with analogue controller.
Using LED SWC intelligent control module, we could achieve unique energy saving adjust mode function after midnight, it saves>15%power 
We could achieve 100% lighting throughout the year and our working duration without sunshine is 5times which is 25-35days longer than regular solar street light. 
Strictly selected high efficiency  class chip, high power, stable output and high transpareny optical glass
By using Nano technology, our battery is waterproof ventilated . This enables us to bury battery underground to achieve optimal constant environment temperature. Battery life span would be much more longer together using with our unique over-charge and over-discharge protection.
LED Lamp
Low light decay LED from U.S., light efficiency >130Lm/m,10000hours light decay≤4%
LED beam angle:150° rectangular light distribution,high edge illuminant. 50W LED lamp ground illuminant equals to 250W sodium lamp(HPS), 30W LED equals to 150W sodium lamp  
How patented controller of SRS works ?
1.Constant current driver consumes 15-20% power when operating. Instead of the traditional LED analogue driver,
our Digital patented controller uses 4 IC to replace it. Only consume 0.0625W power when working. So, further saving 15-20% of power is realized.
2.LED is a semiconductor device which has on-off feature. Due to human visual effect, when frequency over 25t/s, we can not feel. 
Our controller frequency is up to 10K-100Kt/s. through our patent digital controller, we can save 50% power while have the same effect.
 But normally solar street lamps that using constant current driver , supply continuous powr all the time.      
Therefore, we can save 50%  power.  On-site testing saved >47.3%. 
 3.Unique energy saving mode design from our digital controller, after midnight, we could decrease the lamp's power
 gradually to a desired value and keep this value until dawn. Further saving of 10-15% power consumption. 
Other vendors' energy saving mode is to adjust the voltage, current or  power to be a certain value by suddenly.
SRS solar street light system saves 70-85% power consumption compared with other regulars ----5 times longer, to make sure keeps lighting  25-35 days without sunshine. Realizes 100% Lighting by whole year.
Our SRS patent controller uses 4pcs of IC to replace the Constant current driver, so there is no capacitor in our controller. The main material of  IC is silicone, can reach 25-30 years. So our controller life can over 10 years.
How long is life span of the system?
       --Battery, LED and controller
1.Battery Life:
The most important material is electrolyte inside. And there are two important factors to prolong the life span. 
Deep Cycle times--Our solar street light saves 70-85% power consumption compared with regular one. Therefore, each deep cycle time is greatly prolonged. 
Environment Temperature--Most suitable working temperature for battery is 20-25ºC, if higher or less than 10ºC, the life span would be only a half.
×Wrong method:Most vendors put the batteries inside a box hanging on the pole. That is the                    reason why their street light batteries can only have 1 year life,  
√Our suggestion :We are constitutors of National Technical Standard for Solar Photovoltaic Lighting Installation We Bury the battery under ground. SRS sugge                           sts bury the battery under tundra, which is about 0.7-1m deep (consult the local geographic authorities for different situation) 
                          When the battery's working efficiency & life span depends on the temperature, the constant temperature under tundra (about 20-25ºC)
                          could greatly improve performance of battery and life span.
       Why our batteries can be buried under the tundra?                      
 --- Nano Technology Casing 
Our battery casing is designed specially for solar applications, advanced Nano technology is used in the casing, insulation & waterproof of the electrodes are well considered, therefore none electricity leakage & water seepage when buried underground.
Life span of our battery is 5-8 years , others are only 1-2 years normally.
Gel battery: 8-12 years. 
Battery is about 20% of total cost for whole solar street light, changing the battery 5 times means buying another new solar street light within 10 years.
2.LED lamp life: 
Major problem with current high-power LED street light is difficult heat elimination, which result to different light decay. Serious light decay: 
  --45-55 ºC  V.S.  65-75 ºC

Others high power>40 ºC< 4%< 5years

3.  Controller Life
Capacitor is a indispensable device in the Constant Current Driver,  
          its life span: <5 years.
Our SRS patent controller uses 4pcs of IC to replace the Constant current driver, so there is no capacitor in our controller. The main material of  IC is silicone, can reach 25-30 years. So our controller life can over 10 years. 
4.About the details:Cables and Connectors
Our Ultra-violet pure silicone rubber copper wire and Silver-plated high-strength anti-aging waterproof connectors 
helps to reduce the cable system resistance & the power loss in the wire to the minimum extent. This special solar wire, smallest resistance and loss, excellent system reliability, saves energy. 
 Attention: Many non-professional manufacturers think the resistance of solar street lights  are the same as AC powered street lights.
Nothing important to separate them. Following is the compared result for street lights:    
       Solar powered (LED): 240W panel, 24V SYSTEM, I=240/24=10A.  P=10²R=100R, 
       AC  powered (HPS) :  220W sodium lamp, 220V   I=220/220=1A, P=1²R=1R
      Then you can see the difference between their system current (A).   So the cables and connectors are also very important in the system.
