Configurable lighting devices under broadcast control
First Claim
1. A control unit for controlling an illumination parameter of one or more light sources of a plurality of light sources, each of the plurality of light sources being switchable between a disable mode and an enable mode, and the control unit being arranged to:
- select the one or more light sources of the plurality of light sources by switching only the selected one or more light sources into the enable mode,thereby to enable the one or more light sources that are selected and to disable the not selected light sources to cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter and containing no individual addressing information for the plurality of light sources, convert the input signal to the broadcast signal for the plurality of light sources; and
enable the same broadcast signal to be provided to the plurality of light sources after the one or more light sources have been selected, thereby enabling only the selected one or more light sources to comply with the required value of the illumination parameter.

Abstract
A control unit for controlling an illumination parameter of one or more light sources of a plurality of light sources is described. The control unit being arranged to —select the one or more light sources of the plurality of light sources, receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, convert the input signal to a broadcast signal for the plurality of light sources; —enable the broadcast signal to be provided to the plurality of light sources thereby enabling the selected one or more light sources to comply with the required value of the illumination parameter.

1. A control unit for controlling an illumination parameter of one or more light sources of a plurality of light sources, each of the plurality of light sources being switchable between a disable mode and an enable mode, and the control unit being arranged to:
-
select the one or more light sources of the plurality of light sources by switching only the selected one or more light sources into the enable mode, thereby to enable the one or more light sources that are selected and to disable the not selected light sources to cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter and containing no individual addressing information for the plurality of light sources, convert the input signal to the broadcast signal for the plurality of light sources; and enable the same broadcast signal to be provided to the plurality of light sources after the one or more light sources have been selected, thereby enabling only the selected one or more light sources to comply with the required value of the illumination parameter. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 27, 28)

23. A lighting system comprising a central control unit for controlling a configuration of light sources and a control unit for controlling an illumination parameter of one or more light sources of the configuration of light sources, each of the one or more light sources being switchable between a disable mode and an enable mode the control unit being arranged to
select the one or more light sources of the plurality of light sources by switching only the selected one or more light sources into the enable mode, receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, thereby to enable the one or more light sources that are selected and to disable the not selected light sources to cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter, and containing no individual addressing information for the plurality of light sources, and convert the input signal to a control signal for the central control unit, the central control unit being further arranged to receive the control signal and convert the control signal to the broadcast signal and provide the same broadcast signal to the configuration of light sources, thereby enabling only the one or more selected light sources to comply with the required value of the illumination parameter.

24. A lighting system comprising a central control unit for controlling a configuration of light sources and a control unit for controlling an illumination parameter of one or more light sources of the configuration of light sources, each of the plurality of light sources being switchable between a disable mode and an enable mode, and the control unit being arranged to
select one or more light sources of the plurality of light sources, by switching only the selected one or more light sources into the enable mode, thereby enabling the selected one or more light sources and disabling the not selected light sources to cause only the selected one or more light sources to receive a broadcast signal containing no individual addressing information for the plurality of light sources; -
determine a required value of the illumination parameter of the selected one or more light sources; and convert the required value to a control signal for the central control unit, the central control unit being further arranged to receive the control signal and convert the control signal to the broadcast signal and send the same broadcast signal to the configuration of light sources, thereby controlling only the selected one or more light sources to comply with the required value of the illumination parameter.

25. A control unit for controlling an illumination parameter of one or more light sources of a plurality of light sources, each of the plurality of light sources being switchable between a disable mode and an enable mode, and the control unit being arranged to operate in a configuration mode
to select the one or more light sources of the plurality of light sources by providing a first signal to the plurality of light sources to switch only the selected one or more light sources into the enable mode, and to receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, wherein the selected one or more light sources are enabled and the not selected light sources are disabled, to cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter and containing no individual addressing information for the plurality of light sources; - and
the control unit being further arranged to operate in a light-application mode to convert the input signal to the broadcast signal for the plurality of light sources; and to enable the same broadcast signal to be provided to the plurality of light sources while enabling only the selected one or more light sources to comply with the required value of the illumination parameter.

26. A lighting system comprising a central control unit for controlling a configuration of light sources, each of the plurality of light sources being switchable between a disable mode and an enable mode, and a control unit for controlling an illumination parameter of one or more light sources of the configuration of light sources, the control unit being arranged to
select the one or more light sources of the plurality of light sources by switching only the selected one or more light sources into the enable mode, receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, thereby to enable the one or more light sources that are selected and to disable the not selected light sources to cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter, and containing no individual addressing information for the plurality of light sources, and convert the input signal to a control signal for the central control unit, and the central control unit being further arranged to receive the control signal and convert the control signal to the broadcast signal and provide the same broadcast signal to the configuration of light sources, and each light source being arranged to receive the broadcast signal and when selected, to use the broadcast signal to comply with the required value of the illumination parameter.
