【 摘 要 】

Visible light communication is one of the wireless communication that transmits information to receiver trough lighting. The light-emitting diode (LED) lamp is one of the main components that used to transmit information. Generally, LED lamp used to lighting the room because it has energy saving and long lifetime which makes LED lamp as one of the solutions for an energy crisis. This paper discusses visible light communication using the LED lamp for indoor navigation. The transmitted data contains the identity of the LED lamp was modulated on lighting and received by photo-detector for indoor navigation. Transmitting data from LED lamp to photo-detector examined by the height and distance between the line of sight of the transmitter and a receiver. For 30 cm height and at the line of sight, 3-watt transmitter has illumination level of 180 lux, 6-watt transmitter has 273 lux, and 9-watt transmitter has 288 lux. The transmitter using LED lamp can save energy about 88,3% than a compact fluorescent lamp, halogen light bulb, and an incandescent light bulb. A transmitter using visible light increases the energy efficiency for indoor navigation by using the existing infrastructure of the light system.
