Abstract: A smart light source configured for visible light communication. The light source includes a controller comprising a modem configured to receive a data signal and generate a driving current and a modulation signal based on the data signal. Additionally, the light source includes a light emitter configured as a pump-light device to receive the driving current for producing a directional electromagnetic radiation with a first peak wavelength in the ultra-violet or blue wavelength regime modulated to carry the data signal using the modulation signal. Further, the light source includes a pathway configured to direct the directional electromagnetic radiation and a wavelength converter optically coupled to the pathway to receive the directional electromagnetic radiation and to output a white-color spectrum. Furthermore, the light source includes a beam shaper configured to direct the white-color spectrum for illuminating a target of interest and transmitting the data signal.

Abstract: A laser illumination or dazzler device and method. More specifically, examples of the present invention provide laser illumination or dazzling devices power by one or more violet, blue, or green laser diodes characterized by a wavelength from about 390 nm to about 550 nm. In some examples the laser illumination or dazzling devices include a laser pumped phosphor wherein a laser beam with a first wavelength excites a phosphor member to emit electromagnetic at a second wavelength. In various examples, laser illumination or dazzling devices according to the present invention include polar, non-polar, or semi-polar laser diodes. In a specific example, a single laser illumination or dazzling device includes a plurality of violet, blue, or green laser diodes. There are other examples as well.
