Abstract:
(EN) A visible light communication receiver is disclosed. According to an embodiment of the present invention, the visible light communication receiver which comprises a main body; an interference blocking unit which includes an open incident surface on which a visible light signal is incident and a hollow through-path through which the visible light signal passes, which is disposed on a side of the main body, and in which the ratio of the height of the sidewall of the hollow through-path to the effective diameter of the open incident surface is 0.75 or more; a light receiving lens which is disposed at a lower portion of the hollow through-path and concentrates the visible light signal; a light receiving element which receives the visible light signal from the light receiving lens in a lower portion of the light receiving lens and converts the visible light signal into an electrical signal; and a signal processing unit which receives the electrical signal from the light receiving element and generates output data corresponding to the electrical signal is provided.
(FR) L'invention concerne un récepteur de communication par lumière visible. Selon un mode de réalisation de la présente invention, le récepteur de communication par lumière visible comprend un corps principal; une unité de blocage d'interférence qui comprend une surface d'incidence ouverte sur laquelle un signal de lumière visible est incident et un trajet de passage creux à travers lequel passe le signal de lumière visible, qui est disposé sur un côté du corps principal, et dans lequel le rapport de la hauteur de la paroi latérale du trajet traversant creux au diamètre effectif de la surface d'incidence ouverte est supérieur ou égal à 0,75; une lentille de réception de lumière qui est disposée au niveau d'une partie inférieure du trajet traversant creux et concentre le signal de lumière visible; un élément de réception de lumière qui reçoit le signal de lumière visible de la lentille de réception de lumière dans une partie inférieure de la lentille de réception de lumière et convertit le signal de lumière visible en un signal électrique; et une unité de traitement de signal qui reçoit le signal électrique provenant de l'élément de réception de lumière et génère des données de sortie correspondant au signal électrique.
