Definitions

  • the end device must have a suitable light measuring device, i. H. have a device for measuring the ambient light intensity.
  • Suitable circuits with photosensitive elements such as phototransistors are used as sensors, for example.
  • a disadvantage is that such light measuring devices, in particular the sensor, often have a considerable component tolerance, which can lead to errors in the control. In order to at least partially compensate for this tolerance and to reduce the possibility of faulty controls, it would therefore be necessary to adjust each individual device in the production line beforehand in a special measurement setup. This is relatively complex and expensive.

Abstract

L'invention concerne un procédé de commande d'un dispositif d'éclairage d'un terminal en fonction d'une intensité lumineuse ambiante, consistant à déterminer une intensité lumineuse ambiante au moyen d'un dispositif photométrique et à régler une puissance d'éclairage du dispositif d'éclairage sur la base de l'intensité lumineuse ambiante mesurée. Une intensité d'éclairage produite par le dispositif d'éclairage est déterminée au moyen du dispositif photométrique en tant que mesure de compensation. L'intensité d'éclairage ainsi déterminée est comparée à une valeur de référence prédéfinie pour une compensation lors de la commande du dispositif d'éclairage.
