Abstract—As a result of changing in illumination systems, Light
Emitting Diode (LED) lighting system has been widely used
instead of traditional illumination system. The importance of
LED lighting has been increasing day by day because of its less
energy consumption, low production cost, long life and
multiplicity of control algorithm. In recently, several methods
have been used for increasing efficiency of LED lighting system.
In this study, a LED lighting system has designed for a park
illumination. The ratio of daylight has been detected with a
central sensor. This value has been converted into numerical data
and sent illumination pillars that placed into the park with Radio
Frequency (RF).Pulse Width Modulation (PWM) signal required
for buck converter put on the pillars as LED driver is generated
with regard to the numerical data converted from the ratio of
daylight. Thus, brightness of LED has been calibrated and
during the pass of day-night, soft light pass has been provided.
