Abstract

The present disclosure relates to a lighting device (100) comprising a lighting unit (102), at least one application unit (104), and a battery housing (106) comprising a first battery compartment (108) with a first electrical contact set (110) for accommodating and connecting a first battery and with a second battery compartment (112) with a second electrical contact set (114) for accommodating and connecting a second battery, wherein the first and second battery compartments are configured to force an exclusive spatial accommodation of only one of the first and second batteries in the battery housing at a given point in time. The lighting unit is electrically connected to the first electrical contact set for being powered by the first battery in a first operational mode and the application unit is electrically connected to the second electrical contact set for being powered by the second battery in a second operational mode.

First claim

The invention claimed is:

1. A lighting device comprising:
a lighting unit configured to perform a lighting function under a first operational mode of the lighting device;
at least one application unit different from the lighting unit and configured to perform an application function different from the lighting function under a second operational mode of the lighting device;
a battery housing comprising a first battery compartment with a first electrical contact set for accommodating and connecting a first battery, and a second battery compartment with a second electrical contact set for accommodating and connecting a second battery, wherein the first and second battery compartments are configured to force an exclusive spatial accommodation of only one of the first and second batteries in the battery housing at a given point in time; wherein
the lighting unit is electrically connected to the first electrical contact set for being powered by the first battery in the first operational mode; and
the application unit is electrically connected to the second electrical contact set for being powered by the second battery in the second operational mode; and wherein,
the lighting device is configured to perform the lighting function under the first operational mode when the first battery is accommodated in the first battery compartment and perform the application function under the second operational mode when the second battery is accommodated in the second battery compartment; wherein a maximum power requirement of the lighting unit under the first operational mode is different than a maximum power requirement of the at least one application unit under the second operational mode.

2. The lighting device of claim 1 , further comprising a battery identification unit electrically connected to the first and second electrical contact sets and configured to ascertain whether or not the first or second battery is installed, and to provide a battery information signal indicative thereof.

3. The lighting device of claim 2 , further comprising a lighting device control unit, which receives the battery information signal and is configured to control operation of the lighting unit and of the application unit in dependence on the battery information signal.

4. The lighting device of claim 1 , further comprising:
a power input interface configured to receive electrical power from an external power supply device that is different from the first or the second battery;
a first controllable supply switch; and
a power control unit configured to ascertain whether or not a sufficient amount of electrical power is being received via the power input interface, and, when a sufficient amount of electrical power is being delivered, to operate the first supply switch for allowing a transfer of power from the power input interface to the lighting unit or the application unit or to both the lighting unit and the application unit.

5. The lighting device of claim 2 , further comprising:
a charging circuit connected between the power-input interface and at least one of the first and second electrical contact sets, and configured to transform the electrical power received and provide the transformed electrical power via at least one of the first and second electrical contact sets; wherein
the battery identification unit is configured to detect whether or not the installed battery is rechargeable or non-rechargeable and to include the detection result in the battery information signal, and wherein
the power control unit is further configured to receive the battery information signal and to operate the charging circuit in dependence on the battery information signal.

6. The lighting device of claim 3 , wherein,
the application unit is further electrically connectable to the first electrical contact set via a second controllable supply switch;
under a third operational mode of the lighting device, the lighting device is configured to simultaneously operate the lighting unit for performing the lighting function and the application unit for performing the application function; and wherein
the lighting device control unit is additionally configured to control the second supply switch for connecting or disconnecting the application unit from the first electrical contact set.

7. The lighting device of claim 3 , wherein:
the lighting unit is further electrically connectable to the second electrical contact set via a third controllable supply switch;
under a third operational mode of the lighting device, the lighting device is configured to simultaneously operate the lighting device for performing the lighting function and the application unit for performing the application function; and wherein
the lighting device control unit is additionally configured to control the third supply switch for connecting or disconnecting the lighting unit from the second electrical contact set.

8. The lighting device of claim 2 , further comprising:
a communication unit connected to the battery identification unit and configured to receive the battery information signal and to output a battery information message, which comprises battery information, in accordance with a predetermined communication protocol to an external battery monitoring device via a data exchange port.

9. The lighting device of claim 3 , further comprising:
a temperature sensing unit connected to the power-input interface and configured to monitor a temperature value of a predefined position of the lighting device and to provide a temperature signal indicative thereof; and
a thermostatic unit connected to the power input interface, the thermostatic unit configured to receive the temperature signal and to regulate the temperature value of the predefined position according to the temperature signal and to a predefined set-point temperature.

10. A lighting arrangement, comprising:
at least one lighting device according to claim 8 ; and
a battery monitoring device configured to receive, via a data exchange port of the battery monitoring device, the battery information message in accordance with the predetermined communication protocol, and to output a status signal indicative thereof.
