Abstract
The invention relates to a luminaire with a light source comprising: a functional unit; a power supply and control unit configured for converting power from a main power source into a power signal for powering the functional unit; wherein the power supply and control unit is configured to generate a power supply failure signal when the power supply from the main power source fails and to communicate the power supply failure signal to the functional unit.
Claims20
A luminaire with a light source, said luminaire comprising:
- a functional unit;
- and
- a power supply and control unit configured for converting power from a main power source into a power signal for powering the functional unit,
- wherein the power supply and control unit is configured to generate a power supply failure signal when the power supply from the main power source fails and to communicate the power supply failure signal to the functional unit, and
- wherein the functional unit is configured to perform one or more actions upon receipt of the power supply failure signal, and wherein the one or more actions comprise:
- saving data or selecting between setting the functional unit in a power-off mode or a stand-by mode.
A luminaire with a light source, said luminaire comprising:
- a functional unit;
- and
- a power supply and control unit configured for converting power from a main power source into a power signal for powering the functional unit,
- wherein the power supply and control unit is configured to generate a power supply failure signal when the power supply from the main power source fails and to communicate the power supply failure signal to the functional unit,
- wherein the functional unit is configured to perform one or more actions upon receipt of the power supply failure signal, and
- wherein the one or more actions are performed according to a set of priority rules.
A luminaire with a light source, said luminaire comprising:
- a functional unit;
- and
- a power supply and control unit configured for converting power from a main power source into a power signal for powering the functional unit,
- wherein the power supply and control unit is configured to generate a power supply failure signal when the power supply from the main power source fails and to communicate the power supply failure signal to the functional unit,
- wherein the power supply and control unit is connected to the functional unit through a power failure communication line for transferring the power supply failure signal, and
- wherein:
- the functional unit is configured to use the power failure communication line for indicating other information to the power supply and control unit, such as identification data of the functional unit and/or
- the power supply and control unit is configured to use the power failure communication line for indicating other information to the functional unit, such as at least one of:
- identification data of the power supply and control unit;
- a quantity of energy available upon reception of the power supply failure signal;
- and
- a time period during which the functional unit will still be powered by the power supply and control unit.
