8. SOLAR CELL-POWERED WARNING LIGHTS
8.1 General information
This compact, and lightweight warning light consists of
an outdoor Sunceram II cell featuring minimal optical
deterioration, Ni-Cd cell, LED and flashing control
circuit in a single integrated package. The solar cell
recharges the Ni-Cd cell, and it also serves to
discriminate between daytime or nighttime in order to
make the high-brightness LED flash automatically at
night. Install and use the warning light in a location
which is exposed to sunlight.
The unit can easily be secured to a pole using the
stainless steel clamp provided. When it is to be secured,
coating the threaded part of the clamp and screw heads
with epoxy adhesive ensures that the unit will not be
easily dislodged. The light can be designed to flash at
the desired interval. Panasonic is also open to
consultation about special specifications concerning the
unit casing, the color of the LED, the method used to
secure the units, etc.
