Solar street light

タイトルまたは説明

1. Coursertech Co., Ltd.has passed ISO ***1:***0, CE, CCC, ROHS certificates etc. we can control the light decline rate of our LED lightings within *0% after using ****0 hours, the conversion efficiency of light source can reach more than *5%, power factor reach 0.*7. We have got *8 national patents, 1 is invention patent ( for street light reflector ). 2. Solar panel:Our panel conversion efficiency can up to *7%, *0 years life and 5 years guarantee.   3. Battery: We can supply both lead-acid and gel type, over charge and over discharge protection , with high quality; 8~*0 years life, 3 years guarantee.   4. Pole:Our pole is overall hot-dip galvanized, coating color as your requirement, with stainless steel fasteners,*0 years life, *0 years guarantee. 5. LED streetlight:****0 hours , 5 years guarantee. 1> LED ship:   Our adopted LED ship is American Brigelux **0~**0LM/W, but usually it’s only *0~*0 lumens in the market. For example, our *0W light, totally ***0 LM, can get same brightness as *5W from other supplier. (*5W**0LM/W=***0) That is to say, if same brightness, our light power is at least *0% lower than other manufactures, so for aolar light ,it will directly lower the configuration of whole system, and finally to save more money for clients. 2>Heat radiation:  As is known for all, aluminum alloy is the best choice heat dissipation. If use die-casting aluminum, light body temperature will keep more than *0℃.But, our light body which is also the heat radiation made of stretch formed aluminum alloy will keep the temperature only *8℃, which will directly lower light decay, and prolong the lifespan of LED. 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 manufacture who use lens, go against this principle. Our reflector is unique in china,which reach 3 times reflect and make the light efficiency *0% higher than common supplier, meanwhile ,can make the light area broder! For example,our *0W can get *0m diameter illumination area, when other supplier only can get *0m! 4> Intergration design of power supply and control system.  Usually we put this power supply / controller in the pole (under part), because LED itself has a very long life, when led light doesn’t work ,problem mostly is from the power supply, so now we can even ride a bike to exchange if led light doesn’t work, this largely decrease maintenance fee as we needn;t use crane to take the light down to do the repair any more! a)      Full power and half –power energy-saving mode, and adjustable. There is usually *2 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”, even if *2 hours later, if it’s still dark, it will start another circle again, according to the work mode you adjust. b)     Brightness dimmable. There is a dimmer (round part) to adjust the light power. After years using ,if light decay happens ,you can adjust the power higher,to prolong the lifespan of light again. c)      It has *5 protection function including short protection, overload protection, over voltage protection, over current protection, internal hot-cut protection, anti-reverse, anti-thunder more than 4KV etc~ d)     Super high efficiency: power factor is more than 0.*9, conversion efficiency reach *2%. e)      Wide voltage :DC**-DC*0V(CA*****6V), be in common use world widely. f)      It’s dusk to dawn working mode. It will control the light on/off automatically according to the solar radiation when ti’s dusk or dawn. g)     It adopted PWM mode to charge the battery: with ****0% higher conversion efficiency than usual controller in the market; and still has **5% conversion efficiency in cloudy days, when common controller cannot work! h)     When there is insufficient electricity in the battery, discharging stops automatically to protect battery. i)       In the end surface provides a power , as the test . In the case of PV access without removal of PV, pressing the test starts the load power output, after the fixed time, the output load automatically cease to provide load testing.
