65watt led solar street lamp with solar light system
1,key component of solar energy LED street light
1) LED street light;2) LED controller(time controller+light controller);3) Solar panel;4) Battery
2,Functions of Various part
1) Advantage of high power LED
l High efficiency
l Low electricity cost
l Energy efficiency
l High brightness
l No strobe frequency
l Long life
l High impact resistance, High Stability
l good weather ability
2) Solar panel
The solar panel is the hard core of the solar street light system, is also the value highest part. Its function is transforms sun's emissivity into the electrical energy,or escorts to the accumulator to save,or impetus load work.
The function of the solar energy controller is to control the whole system's working condition,and has the overdischarge Protection function to the the accumulator. In the big temperature difference place, the qualified controller should also have the temperature compensation function. Other additional function like light-operated switch,time switch must be the option of the controller
Generally it is the lead-acid battery, also can use nickel hydrogen battery, nickel cadmium cell or lithium battery. Its function is store up the electrical energy which sent out from the solar cell when it has the illumination.
3,Operational principle of solar LED street light
Utilizing photovoltaic effect principle, maked the solar panel. Daytime, the solar panel receives the solar radiant energy and translate into the electrical energy output, pass charge controller, Stores up in the accumulator cell. Night when the illumination gradually reduces to about 10Lux, the solar panel open-circuit voltage is about 4.0V,charge controller sense the voltage, accumulator discharge to the lamp.
