WIDE ANGLE OPTICAL WIRELESS TRANSMITTER INCLUDING MULTIPLE NARROW BEAM WIDTH LIGHT EMITTING DIODES

摘要

Certain configurations of optical wireless communication devices that comprise a plurality of narrow beam width light emitting diodes to provide a wide-angle transmitter are described. The transmitter can be used, for example, in optical wireless communication systems. The transmitter can be designed to select one of the light emitting diodes that points towards the receiver for more reliable information exchange or data transmission. The particular light emitting diode used may change as a position of an end user changes.
