solar street light - TL001

, Light source

We can know the character of LED from the following three points:

(1) optical light we have the self-packing technology so that we can control the quality of our products. Now the optical light can reach 90LM/W.

(2) radiator there is a radiator of 15mm or 20mm,which is made of Aluminum. It longer the life time of LED by the way of thermal.

(3) light failure we can judge the light failure by the quality of chips and the design of circuit. Now the life of the whole can reach 100thousand hours.

2, solar panels

Solar panel is a key factor of the life time, we uses imported Silicon and the conversion rate can reach 17%, which is technology. We use the installation of Series-parallel connection, which reduce the area of solar panel and improve the wind resistance of the divice. It uses the voltage of 12V-36V-48V.

3, microcompueter intelligent controler

The controller relays on the research development of Science and Technology University of China and Hefei Indursity University. It has the function of pluse charge discharge rather than the direct charge and direct realease, which protects the battery. Besides that, it has the function of avoiding over charge and over discharge, temperature compensation, anti-thounder, and discharge depthly once two year.

4, pole

The use of aluminum die-casting, hot-dip galvanizing anti-corrosion surface treatment coating, polishing

5, battery

We have the battery of our own brand. It has the function of discharging depthly. The discharge voltage can reach to 9V, while the battery from many other factory can only reach 10V. The normal voltage of battery is about 12.8V. So. We can have such conclusion that the efficiency of our battery is 30% higher than others12.8-10=2.8 V,12.8-9=3.8V . Beides that, many factories increase the capacity of battery to increase the days of continous rainy days. It is not reasonable because if the capacity of the battery is too large, the battery will always in the state of power loss, which influence the life of battery in some content. Now we can get the conclusion that only the reasonable configuration can have the best effect. The shell of the battery has the function of waterproof and good ventilation.

When it comes to the whole set, the overall structure is reasonable and thelamp has the function of waterproof. It can normally work for 15 continous rainy days.
