Claim Text:
1. A light communication system, comprising: a transmitter including a first processing unit that generates a transmission signal, and at least two light-emitting diodes arranged in a first column that emit light that carries the transmission signal; and a receiver including at least two first variable lenses arranged in a second column that correspond to the at least two light-emitting diodes in the first column to receive the light emitted by the at least two light-emitting diodes and change a propagation path of the light, at least two photosensitive elements arranged in a third column that correspond to the at least two first variable lenses in the second column to sense the light passing through the at least two first variable lenses to produce receiving signals, and a second processing unit that respectively controls the at least two first variable lenses according to signal qualities of the receiving signals of the at least two photosensitive elements in order to change equivalent channels between the transmission signal of the first processing unit and the receiving signals of the at least two photosensitive elements.
