Saat ini lampu penerangan ruangan banyak menggunakan LED (Light Emiting Diode) sebagai komponen utamanya, dan diperkirakan untuk 10 tahun ke depan penggunaan lampu sebagai alat penerangan sudah seluruhnya menggunakan lampu jenis ini. Sementara itu lampu hanya digunakan sebagai alat penerangan ruangan saja. Secara teoritis cahaya dari lampu jenis LED bisa digunakan sebagai media transmisi kecepatan tinggi. Visible Light Communication adalah sistem komunikasi yang menggunakan cahaya tampak sebagai media transmisi menggunakan komponen LED.Dalam penelitian ini, dikembangkan sebuah perangkat VLC untuk mengirimkan sinyal video analog. Sinyal video dikirimkan melalui LED di blok transmitter. Kemudian diterima oleh blok penerima, dengan photodiode sebagai penerima informasi. Dalam proses pengirimannya, sinyal video dibagi menjadi dua bagian, yaitu sinyal suara dan video. Hasil penelitian ini, dapat diperlihatkan bahwa sinyal video dapat dikirimkan melalui perangkat VLC dengan jarak 75 cm.
