Solar
yard lights are very efficient devices which harness the
power of daylight to provide lighting for the night. An important function
of these lights is that of safety. They can be used to light up otherwise
treacherous pathways and steps. In addition to that, there is no need
to worry about these lights not working in the event of a power outage.
Another advantage to solar yard lights is that most of them have sensors
which detect the onset of both dusk and dawn. This feature causes them
to automatically turn on or off, as appropriate. In this way, a homeowner
may be assured that their yard will be lit up at night, even if he or
she is away on vacation.
The basic components of solar yard lights are the casing, a NiCd battery,
a small solar panel, a light sensor, and an LED light. Common materials
which make up the casing include plastic, copper, and stainless steel.
Most of these lights use LEDs for illumination, but some use fluorescent
bulbs.
Many of these solar lights are self-contained and simply need to be
placed in the yard where they will receive the plenty of sunlight. There
are, however, sets of outdoor solar lights which are all connected to
a single solar panel. These lights can be placed in shaded areas as
long as the panel is placed in the sun.
