Abstract

A system for controlling a group of lighting units, the system including a narrow-beam infrared remote control unit configured for communicating a first control signal to a first lighting unit of the group of lighting units via an infrared frequency communication link, wherein the first lighting unit is configured to: (a) perform an operational mode in response to the received first control signal; and (b) communicate a second control signal from the first lighting unit to at least a second lighting unit of the group of lighting units via a first radio frequency communication link whereby said second lighting unit is configured to perform an operational mode in response to the received second control signal.

Claims

1. A system for controlling a group of lighting units, the system including a narrow-beam infrared remote control unit configured for communicating a first control signal to a first lighting unit of the group of lighting units via an infrared frequency communication link, wherein the first lighting unit is configured to:

(a) perform an operational mode in response to the received first control signal; and

(b) communicate a second control signal from the first lighting unit to at least a second lighting unit of the group of lighting units via a first radio frequency communication link whereby said second lighting unit is configured to perform an operational mode in response to the received second control signal;

wherein a radio frequency remote control unit is configured for communicating with the first lighting unit and the second lighting units via a second radio frequency communication link so as to define the first lighting unit and the second lighting unit as part of the group of lighting units.

2. A system as claimed in claim 1 wherein the radio frequency remote control unit includes at least one of a mobile telephone device, a tablet type device, a desktop computer device, a portable computer device, and a personal digital assistant.

3. A system as claimed in claim 1 wherein the radio frequency remote control unit includes a software application module operable for running on the radio frequency remote control unit to provide a user-interface for controlling the group of lighting units.

4. A system as claimed in claim 1 wherein the radio frequency remote control unit is, in response to a user input command entered via a user-interface, configured for programming at least one of the first and second lighting units in the group of lighting units to perform user-defined operational modes, and wherein the narrow-beam infrared remote control unit is thereafter configured for selectably controlling the at least one of the first and second lighting units to perform any one of the user-selected operational modes that have been programmed into the at least one of the first and second lighting units.

5. A system as claimed in claim 1 wherein the first and second radio frequency communication links include at least one of a WI-FI type and a Bluetooth type radio frequency communication link.

6. A system as claimed in claim 1 wherein in response to the received second control signal, the second lighting unit is configured to perform the same operational mode as performed by the first lighting unit in response to receiving the first control signal.

7. A system as claimed in claim 1 wherein the operational modes performed by the first lighting unit and the second light unit includes at least one of outputting a colour output mode, a brightness dimming mode, and switching the first lighting unit on or off.

8. A system as claimed in claim 1 wherein the first lighting unit and the second lighting unit include an inbuilt WI-FI communication module for receiving and transmitting WI-FI signals and an infrared communication module for receiving and transmitting infrared signals.

9. A system as claimed in claim 1 where in the infrared remote control unit and the radio frequency remote control are integrally formed in a common device.
