Method for changing the identification code of a light source in visible light communication systems

A driver system configured to drive a light source, the driver system comprising:

• a control unit;
• a light driver,
• wherein the light driver is configured to convert energy provided by a power source into a form suitable for the light source, and wherein the control unit is configured to control the light driver such that the light source emits modulated light comprising at least an identification code;
• and
• a receiver arranged to receive signals from nearby mobile devices,
• wherein the control unit is further configured to change the identification code from a first ID code to a second ID code upon receiving from one of the nearby mobile devices a second signal by the receiver of the driver system, the second signal comprising a command to change the identification code of the light source, the command being received by the driver system in response to a determination by a server that the identification code of the light source is to change from a first ID code to a second ID code and transmitting by the server, in response to the determination, a first signal to the mobile devices, the first signal comprising the command to change the identification code of the light source.

A visible light communication system comprising:

• a light source;
• a driver system;
• a server;
• and
• a mobile device,
• wherein the driver system is configured to drive the light source such that the light source emits a modulated light comprising at least an identification code associated with the light source,
• wherein the mobile device is configured to receive the identification code from the light source to identify the light source,
• and wherein the server is configured to allow the mobile device to identify the light source, and to initiate a change of the identification code of the light source by sending a first signal comprising a corresponding command to the mobile device, and to update the identification code of the light source upon receiving a confirmation of the changed identification code from the mobile device,
• wherein the mobile device is further configured to receive from the server the first signal comprising the command to change the identification code of the light source, to relay to the driver system the command to change the identification code of the light source by sending a second signal comprising the command to change the identification code of the light source, after the network adapter of the first mobile device receives from the server the first signal comprising the command to change the identification code of the light source, to receive a confirmation of the change of the identification code from the driver system, and to relay the confirmation to the server, and
• wherein the driver system is further configured to receive the second signal comprising the command to change the identification code of the light source from the mobile device, to change the identification code accordingly, and to send the confirmation to the mobile device.
