Intelligent lighting control

A lighting arrangement comprising

• a plurality of luminaire units, each provided with at least one dedicated light source and at least functionally connected control logic entity with a wireless transceiver, said plurality of luminaire units being configured to communicate via a mesh network established utilizing the wireless transceivers thereof, wherein at least one of said luminaire units is at least electrically connected to a user-operable switch device, preferably at least two positions providing power switch such as a wall-mounted on/off switch, for controlling the luminaire unit, and
• the control logic entity associated with said at least one luminaire unit being configured to, upon detection of a predetermined signal responsive to the operation of the control switch device, transmit a predetermined message via the wireless transceiver to enable other luminaire units in the mesh network receiving the message to execute a responsive luminaire, optionally light source, control action as configured in the control logic entities thereof relative to the captured message.

A method for controlling a plurality of luminaire units, each provided with at least one dedicated light source, such as a LED (light-emitting diode), and at least functionally connected control entity with a wireless transceiver, said plurality of luminaire units being configured to communicate via a mesh network established utilizing the wireless transceivers thereof, wherein at least one of said luminaires is electrically connected to a user-operable switch device, preferably an on/off power switch such as a wall on/off power switch, for controlling the luminaire, said method comprising

• detecting, at said at least one luminaire, signal, optionally signal sequence, triggered by switching action,
• determining, in response to said detection, at said luminaire unit a control action of the at least one light source and a message to be wirelessly transmitted in said mesh network to enable other luminaire units in the network to execute a responsive luminaire control action as configured in the control logic entities thereof based on the captured message, and
• executing the control action and transmission of the message.
