VISIBLE LIGHT COMMUNICATION VIA SOLID STATE LIGHTING DEVICES

摘要

A solid-state lighting fixture includes a first group of solid-state light elements, a second group of solid-state light elements, and a light control module. The first group of solid-state light elements is configured to emit visible light at a first wavelength. The second group of solid-state light elements is configured to emit light at a second wavelength, which is different from the first wavelength. The light control module is configured to modulate the light emitted from the first group of solid-state light elements and modulate the light emitted from the second group of solid-state light elements, respectively, such that the modulation pattern of the emitted light from each one of the first group of solid-state light elements and the second group of solid-state light elements communicates a first subset of data and a second subset of data, respectively, while being undetectable to the human eye.
