Abstract

L'objectif de l'invention est de permettre de déterminer facilement la présence d'objets. À cet effet, l'invention propose un système d'éclairage comprenant un dispositif lumineux (LE) et un dispositif émetteur (SE) disposé dans le dispositif lumineux (LE) ou directement à côté de celui-ci pour transmettre sans fil un signal. Le système d'éclairage présente en outre un dispositif récepteur (EE) se trouvant à un emplacement fixe par rapport au dispositif émetteur (SE), tout en étant séparé physiquement de celui-ci, pour recevoir un signal d'analyse (RW) provoqué par le signal (SW) et pour produire un signal de réception correspondant. Le système d'éclairage dispose en outre d'un dispositif d'évaluation (IS) pour évaluer le signal de réception concernant son intensité.
