Abstract
Lighting devices with lighting means, transmitting device for transmitting an electromagnetic data signal and energy buffer for current supply of the transmitting device are to be protected from exhaustive discharge. Thereto, an activation device is provided, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal.
Claims18
A lighting device comprising:
- an illuminant,
- a transmitting device for transmitting an electromagnetic data signal, and
- an energy buffer for current supply of the transmitting device, and
- an activation device, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal;
- wherein:
- the activation device is configured to determine when periodic switching cycles of the transmitting device occur;
- and
- the activation device is configured to activate the transmitting device or keep the transmitting device activated despite an activated exhaustive discharge protection in case of internal current supply.
A method for operating a lighting device comprising:
- an illuminant,
- a transmitting device for transmitting an electromagnetic data signal,
- an energy buffer for current supply of the transmitting device,
- an activation device, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal;
- wherein the activation device comprises a computing unit configured to determine a state of charge of the energy buffer;
- wherein the method comprises:
- determining, by the activation device, when periodic switching cycles of the transmitting device occur;
- and
- activating the transmitting device or keeping the transmitting device activated, by the activation device, despite an activated exhaustive discharge protection in case of internal current supply based on when the periodic switching cycles of the transmitting device occur.
