Operating method for operating unit of illuminant, involves connecting light sensor with interface entrance of operating unit, where interface entrance conserves passive electronic element for receiving actively transmitted signal

摘要

The method involves connecting a light sensor with an interface entrance (5) of an operating unit (2). The interface entrance conserves a passive electronic or opto-electronic element for receiving an actively transmitted signal. A photo sensor, which is the passive element, transmits the actual value of brightness to the operating unit. The element is an acoustic sensor, a vibration sensor or a pressure sensor. The actively transmitted signal is an analogous signal or a digital signal. The passive element is a potentiometer. Independent claims are also included for the following: (1) a system for operating an illuminant (2) a method for wireless communication between two operating unit for an illuminant (3) a system for wireless communication between two operating unit for an illuminant.
