In this work fiber optic lighting system (FOLS) operation is
checked to determine its efficiency and performance. This fiber system
consists of high intensity discharge metal halide lamp connected to fiber
bundle, which guide light to several lenses. These lenses illuminate the
desired place. It is shown that this (FOLS) is more preferable since it is
less energy consuming. It has also ultra violet (UV) and infra – red (IR)
filters. This (FOLS) is also more safe and flexible and can be also easily
maintained. It can be also used in water and dangerous places like that in
which humidity is large.
Fixtures were placed in suitable locations and then connected to the
illuminators by the fiber optic cables. Where their intensity were found to
be changed with the radius and length of the optical fiber.
From the calculation it is concluded that the length and the radius
of the optical fiber plays an important role in energy losses including
absorption and dispersion of the light intensity from core of fiber optic
cable.
As the length of the fiber optic cable increases the absorption
increase, while increase in the radius of the fiber increases dispersion and
in turn decreases light intensity. Those two factors are the most important
for controlling the use of the optical fiber. |
