Specification :

Here are the best wind-solar LED street lights. They are designed from Gongda Hiyu' s own patents. It has high performance with wider light distribution, higher horizontal illuminance, best glare control, higher reliability and excellent energy-protect.

SPECIFICATIONS
Height: 12-M pole height, Galvanized, Powder Coating
System Voltage: DC12/ 24V
Working Time: 4-12h/ day ( Customized)
Cloudy and Rainy days: 2-7days ( Customized)
Wind turbine: High-quality permanent magnet was used. Wind turbine is specially designed to reduce the start-up torque of alternator. Rotor blades are producted by precision injection molding process to make blades exceptional consistency of aerodynamic outline and mass distribution that ensures the rotors to operating at nearly no noise and minimal vibration. Wind turbine body is made from high-quality aluminum by precision casting process to enhance its fitness and excellent finishing.
Solar panel: Its task is to convert the sun' s energy into electricity. Different sizes and power outputs are available. They have to be carefully chosen for the desired application. Solar panels should be able to withhold and deliver in extreme weather conditions. Some are even designed unbreakable ( vandal proof) ; Others will work well in overcast weather.
Lamps: CREE LED, have a good color rendition. A cluster of extra or ultra bright LEDs forms the lamp. LEDs consume a fraction of the energy of comparable lighting and have a very long life span. Wind solar hybrid lights are an emerging and promising application for LED technology.
Controllers: The lights automatically come on at dusk when a photosensitive cell detects that it' s dark. It automatically turns off the turbine when wind speeds get too high, and also alerts human operators when problems need to be addressed or maintenance is required.
Storage Battery: Maintenance-free. To providing energy for dusk to dawn operation, they must also be able to supply few days of backup power in case of bad weather or charger failure.
