Title (EN) ILLUMINATION LIGHT COMMUNICATION DEVICE AND ILLUMINATION LIGHT COMMUNICATION METHOD
(FR) DISPOSITIF DE DIFFUSION DE SOURCE LUMINEUSE ET PROCÉDÉ DE DIFFUSION DE SOURCE LUMINEUSE
(JA) 照明光通信装置および照明光通信方法
Abstract:
(EN) White light emitting diodes (11A, 11A, ...) emits illumination light modulated by communication information. A light quantity control unit (13) controls generation of the illumination light or modulation by a modulation unit (12) so that the light quantity of the illumination light per a predetermined period is constant. For example, the light quantity control unit (13) performs biphase encoding for the communication information.
(FR) La présente invention concerne des diodes électroluminescentes blanches (11A, 11A,...) émettant une lumière d'éclairage modulée par des informations de communication. Une unité de régulation de la quantité de lumière (13) contrôle la production de la lumière d'éclairage ou la modulation par une unité de modulation (12), de manière à rendre constante la quantité de lumière d'éclairage générée au cours d'une période définie. L'unité de régulation de la quantité de lumière (13) exécute par exemple le codage biphasé des informations de communication.
(JA) 白色発光ダイオード(11A、11A、…)からは、通信情報によって変調された照明光が発せられる。光量制御部(13)は、この照明光の所定期間当たりの光量が一定となるように、照明光の発生または変調部(12)による変調処理を制御する。例えば、光量制御部(13)は、通信情報に対しバイフェイズ符号化処理を行う。
