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.
