Özet:

Light emitting diodes (Light Emitting Diodes, LED) provide an environment-friendly lighting opportunity with high energy efficiency and long life compared to

traditional lighting devices. Therefore, their use is becoming more and more common today.

Also, the ability to switch LEDs at high speeds makes them good transmitters for short-range wireless optical communication. For this reason, data transmission can also be

performed by changing the power or color of the lighting at speeds that the human eye cannot

notice, especially by using LED. This technology is called Visible Light Communication

(VLC). VLC attracts attention as an alternative or complementary technology to RF due to

the VLC is more reliable, inexpensive and efficient compared to radio frequency (Radio

Frequency, RF) communication and the RF band is getting more and more crowded.

In this study, an LED driver is designed that can perform data transmission while

providing lighting conditions for indoor VLC systems. The designed LED driver supports

multi-level modulation when using Metal oxide semiconductor field effect transistors (Metal

Oxide Semiconductor Field Effect Transistor, MOSFET) as switch, making the transmitter

system easy to design and low cost.
