solar street light

 

 

 

Working principle

Solar energy is unlimited clean energy. Solar street lights make the most use of the unlimited energy. Electricity is gained and stored from sun. It is good for the Earth and there is no pollution. Solar street lights transform natural energy of sun into power and store it in accumulator through solar panel. Accumulator provides electricity automatically to light the light. When the light is lit, timer begins to time. The light will go out after a specific period of time. When sunlight falls on the panel in the daytime, panel transforms light energy into electric energy through special controller and it is stored in accumulator. When accumulator’s voltage rises to fixed voltage, controller will stop charging to prevent overcharge. When it becomes dark in the evening, the light will light automatically because of controller’s light-control function. Controller can set time, so people can set the time of lighting the light according to requirements. When accumulator’s power reduces to certain voltage, controller will stop supplying power to prevent overfall. It can protect accumulator and extent accumulator’s useful life. When the sunlight is sufficient, accumulator can have enough power. Accumulator can also supply power on rainy days so lights can work normally.

Advantages

Wireless application:

Integrated solar panel, LED, lithium battery, micro-controller and other accessories into one system, simple and stylish.

Micro-computer controlled:

Combine motion sensor system,light control system and time control system perfectly, ensure whole system more energy-efficient.

Easy installation:

No power required, no cables required, easy installation in 5 minutes

Solar panel angle adjustable:

Adjustable in vertical and horizontal direction, ensure maximum efficiency of solar energy conversion.

Good heat dissipation:

Solar panel, battery and light body do not connect directly, they’ll not conduct heat to each other, to support good heat dissipation and long lifetime.

Extreme light:

Light efficiency reach 160lm/w, at same illumination, lower watt available.

Lithium battery:

Adopt lithium battery to replace traditional gel battery, longer lifetime.

Modular design:

All components are modular design and in standardized production.

Battery can be easily replaced if needed.

Low cost:

Compared with traditional solar led lights, much lower cost, easy to transport.
