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.

2. A lighting system comprising a central control unit for controlling a plurality of light sources, and a local control unit for controlling an illumination parameter of one or more of the light sources of the plurality of light sources,
the local control unit being arranged to operate in a first mode to: -
select the one or more light sources by providing a first signal to the plurality of 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 receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, and convert the input signal to a control signal for the central control unit; and the central control unit being arranged to; receive the control signal and convert the control signal to the broadcast signal; and provide the same broadcast signal to the plurality of light sources, thereby arranging each light source to; receive the broadcast signal and when selected, use the broadcast signal to comply with the required value of the illumination parameter. - View Dependent Claims (3, 19, 20)

4. A control unit for controlling an illumination parameter of one or more light sources of a plurality of light sources, the control unit being arranged to operate in a first 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 cause only the selected one or more light sources to respond to a broadcast signal representing the required value of the illumination parameter, and receive an input signal representing a required value of the illumination parameter for the selected one or more light sources, the control unit being further arranged to operate in a second mode to; convert the input signal to the broadcast signal for the plurality of light sources; and provide the same broadcast signal to the plurality of light sources thereby enabling only the selected one or more light sources to comply with the required value of the illumination parameter. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 21)
