ALLTOP waterproof 20w solar street light directly sale for garden

The Solar&wind street Light is a revolutionary product by utilizing Photovoltaic effect and wind power. It is designed to constantly absorb solar energy in daylight,wind energy all the day and convert to electricity, the intelligent controller could precisely control the charge, discharge and well preserve electricity into the lithium battery. 

And start to iluminate, which is powered by the lithium battery, once the iluminance of ground reduced to 15 lux in night time, or solar panel voltage drop to 5V below. The intelligent controller not only protects the battery from over-charging,over-discharging, but also can control the light switch-on,the time of swicth-on and optimize the brightness effectively according to the real-time environment.

> Starts non loaded: Minimum speed is 2m/s to start the wind turbine.

> Electronic braking system: Braking system will turn on automatically when wind speed ≥ 35m/s. 

> Discharging while charging: At night, the wind turbine workes to support the LED lighting and also charge the battery.

> Daytime and nighttime will be recognized according to the output voltage of solar panel. When nightfall, the LED lighting operates; when daytime, charge the battery.

> With MPPT technology, the battery will be charged max by the sunlight.

> Utilize ligh effiency LED, with integrated opticallens. PWM adjustment, constant current output.

> PIR motion sensor: enter energy-saving mode when nobody to prolong backup days. 

> RED pathway indicator, for warning effect and decoration at night.

Strong light environment (daytime) does not light up!

In the low light environment or at night, the sensor body detects the change of infrared heat energy caused by the movement of the human body and then triggers the lighting. Sensing diameter is farther and more sensitive.
