Abstract

A lighting system ( 100 ) comprising a central lighting device ( 111 ), at least one satellite lighting device ( 121, 131 ), and a controller ( 141 ) for adjusting light settings, is provided. The controller is arranged for transmitting, in response to a user request ( 140 ), an association request over a first communication link ( 142 ). The central lighting device is arranged for receiving the association request and re-transmitting the association request over a second communication link by means of coded light ( 112 ). The satellite lighting device is arranged for transmitting, in response to receiving the association request, its identifier to the central lighting device. The identifier is only transmitted if an association process is enabled. The association process is enabled, in response to a user request, during a limited time period. The central lighting device is further arranged for associating, in response to receiving the identifier, the satellite lighting device with the central lighting device.

First claim

1 . A lighting device comprising:
a light source being arranged for emitting coded light, first communication means being arranged for transmitting or receiving data over a first communication link, second communication means being arranged for transmitting or receiving data over a second communication link by means of the coded light, and controlling means being arranged for:
receiving an association request over the first communication link,
transmitting the association request over the second communication link,
receiving an identifier of a satellite lighting device, and
associating the satellite lighting device with the lighting device.

2 . The lighting device according to claim 1 , wherein the second communication means is arranged for:
transmitting data over the second communication link by modulating the light emitted by the light source, or receiving data over the second communication link by demodulating light detected by a light detector.

3 . The lighting device according to claim 1 , wherein the controlling means is further arranged for:
receiving light settings over the first communication link, adjusting, under the condition that the light settings are intended for the lighting device , the properties of the emitted light in accordance with the light settings, and transmitting the light settings over the second communication link.

4 . A lighting device comprising:
a light source being arranged for emitting coded light, communication means being arranged for transmitting or receiving data over a second communication link by means of the coded light, and controlling means being arranged for:
receiving an association request, and
transmitting, under the condition that an association process is enabled,
an identifier of the lighting device over the second communication link.

5 . The lighting device according to claim 4 , wherein the association process is enabled during a predetermined time period after the lighting device has been powered on for the first time.

6 . The lighting device according to claim 4 , further comprising a user-operable element, wherein the association process is enabled during a predetermined time period after the user-operable element has been operated.

7 . The lighting device according to claim 4 , wherein the association process is enabled during a predetermined time period after a reset request is received by the communication means.

8 . The lighting device according to claim 4 , wherein the communication means is arranged for:
transmitting data over the second communication link by modulating the light emitted by the light source, or receiving data over the second communication link by demodulating light detected by a light detector.

9 . The lighting device according to claim 4 , wherein the controlling means is further arranged for:
receiving light settings, and adjusting, under the condition that the light settings are intended for the lighting device, properties of the emitted light in accordance with the light settings.

10 . A lighting system comprising:
a central lighting device according to claim 1 , a satellite lighting device, and a lighting control device, the lighting control device and the central lighting device being arranged for communicating over the first communication link, and the central lighting device and the satellite lighting device being arranged for communicating over the second communication link, wherein the lighting control device is arranged for transmitting, in response to a user request, an association request over the first communication link.

11 . The lighting system according to claim 10 , wherein the lighting control device is further arranged for transmitting, in response to a user request, light settings intended for the central lighting device, the satellite lighting device, or both, over the first communication link.
