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 .
