Unipeu Solar LED Street Light Advantages

1. Solar panel: we have a Strategic Partner

with long-term relationships, panel

conversion efficiency can be up to 17%; 20

years life, 5 years guarantee.

2. Battery: we can supply both lead-acid and

gel type, and our battery supplier is also

selected by us after long-term test and

practice, reliable, and of high quality; 8~10 years life, 3 years guarantee.

3. Pole: our pole is overall hot-dip galvanized, coating color according to your requirement,

with stainless steel fasteners, safter than welding tpye; 20 years life, 10 years guarantee.

4. LED street light: 50000 hours life, 5 years guarantee

1> LED chip is American Bridgelux with 120~130LM/W, but usually it’s only 80~90lumens

in the market. That is to say, if the same brightness, our light power is at leat 20% lower

than other manufactures, which leads to lower configuration for whole system, and finally

to save more cost for clients!

2> Constant-current power supply and control system intergrated: usually we put this

controller in the pole (under part), because LEDs itself has a very long life, we can even

ride a bike to exchange the controller if led light doesn't work, this largely decreases

maintenance fee as we needn't use crane to take the light down to do the repair any more!

3> Light reflector: LED main characteristic is light source collected, so it’s firstly important

thing to make LED source diffusion and uniformization. This is the design principle of

our reflector, when manufactures who use lens, go against this principle. Our reflector is

unique in China, which reach 3 times reflect and make the light effeciency 30% higher

than common supplier, meanwhile, can make the light area broader! For example, our

32W can get 30m diameter illumination area, when other supplier only can get 20m!

Products photos in details:

This is our reflector, which can make our

light illumination wider than other

suppliers!

This is our back of led street light: light

body and alluminum alloy heat-cooling

structure intergrated! Different from

die-casting type!

This is our 56W led street light, with

broader luminous body than usual

manufactures!

5. Controller: 4~5 years life, 3 years guarantee.

1> It’s dusk to dawn working mode. It will control the light on/off automatically according to

the solar radiation situation when it’s dusk or dawn.

2> Full power and half-power energy-saving mode, and asjustable. There is usually 12 dip

switches at one end of controller, which is for adjusting the full power and half power.

"UP-H if full power; DOWN-L is half power", and even if after 12 hours later, it's still

dark, it will start another circle again, according to the work mode you adjust.

3> It adopts PWM mode to charge the battery, with 20~30% higher conversion efficiency

than usual controllers in the market; and still has 4~5% conversion efficiency in cloudy

days, when common controller cannot work!

4> When there is insufficient electricity in the battery, discharging stops automatically to

protect battery.

5> In the end surface provides a power button, as the test button. In the case of PV access

without removal of PV, pressing the test button starts the load power output, after the

fixed time, the output load automatically cease to provide load testing.

6> It has 15 protection functions including short circuit protection, overload protection, over

current protection, internal hot-cut protection etc.

7> We can design the remote control function to realize the full-power and half-power

energy-saving mode for clients if needed.

8> Constant-current power supply and control system intergrated: usually we put this

controller in the pole (under part), because LEDs itself has a very long life, we can even

ride a bike to exchange the controller if led light doesn't work, this largely decreases

maintenance fee as we needn't use crane to take the light down to do the repair any more!

This is one end of our controller, with

full-power and half-power

evergy-saving mode adjustion

function.

Another end, with very clear

indication of wire connection.

Thank s for your intresting in our Solar Led Lights.

Hope that would be help for your design.
