Title (EN) INTELLIGENT VISIBLE LIGHT WITH A GALLIUM AND NITROGEN CONTAINING LASER SOURCE
(FR) LUMIÈRE VISIBLE INTELLIGENTE AVEC SOURCE LASER CONTENANT DU GALLIUM ET DE L'AZOTE
Abstract:
(EN) 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.
(FR) L'invention concerne une source de lumière intelligente configurée pour une communication de lumière visible. La source de lumière comprend un dispositif de commande comprenant un modem configuré pour recevoir un signal de données et générer un courant de commande ainsi qu'un signal de modulation d'après le signal de données. De plus, la source de lumière comprend un émetteur de lumière configuré comme un dispositif de lumière de pompage permettant de recevoir le courant de commande pour produire un rayonnement électromagnétique directionnel avec une première longueur d'onde de pic dans le régime de longueur d'onde ultra-violette ou bleue modulée afin de transporter le signal de données à l'aide du signal de modulation. De plus, la source de lumière comprend un trajet configuré pour diriger le rayonnement électromagnétique directionnel, ainsi qu'un convertisseur de longueur d'onde couplé optiquement au trajet pour recevoir le rayonnement électromagnétique directionnel et émettre un spectre de couleur blanche. De plus, la source de lumière comprend un dispositif de modelage de faisceau configuré pour diriger le spectre de couleur blanche permettant d'éclairer une cible d'intérêt et de transmettre le signal de données.
