The photovoltaic process is completely solid-state and self-contained.
There are no moving parts and no materials are consumed or emitted.
Solar power modules gather solar energy in the form of sunlight and convert it into direct current (DC) electricity.
The park light will be operated in all weather conditions, with the energy stored in the battery .
A complete solar powered park light includes solar module, system regulator, battery and the LED lighting aspect
The Light Emitting Diode (LED) is a semiconductor-based electronic light source which transforms more than 90% of its power into light.
A typical LED lamp consists of a semiconductor chip mounted in a reflecting cavity on metal leads, and then encapsulated in clear epoxy.
With the advantage of LED (long lifespan and low power consumption) the park light is ideally made for LEDs and powered by the clean energy of the sun.
Battery storage allows operation at night or overcast weather.
System regulator includes circuit protection for solar module and loading, and prevents battery over charging/discharging . |
