Title: LIGHTING APPARATUS WITH CURRENT LIMITING FOR COMMUNICATION DEVICE
Abstract:
Flicker or dimming of an illuminant interconnected with a communication device or a beacon (B1) is intended to be avoided. What is proposed for this purpose is a lighting apparatus having an illuminant (L1), a communication device (B1) arranged in or on the illuminant (L1), for wireless transmission and/or reception, and a current supply device for supplying the illuminant (L1) and the communication device (B1) with current. The lighting apparatus additionally has a current limiting device (SB) for limiting a current from the current supply device to the communication device (B1). Furthermore, provision is made of a control device (IV) for controlling the current limiting device depending on a software state of the communication device (B1) and/or a state of charge of an intermediate energy store of the communication device.
