1. A method for transmitting lighting device data, the method comprising the steps of:
- obtaining, in a lighting device, a plurality of subsets of lighting device data, the lighting device data containing information related to the lighting device, the plurality of subsets jointly corresponding to the complete lighting device data;
combining the lighting device data within modulated illumination light;
transmitting from the lighting device embedded in modulated illumination light one of the plurality of subsets of lighting device data,determining whether the complete lighting device data has been transmitted;
waiting a predetermined amount of time if all subsets have not been transmitted;
repeating the above steps until all of said plurality of subsets jointly corresponding to the complete lighting device data have been transmitted and if all subsets have been transmitted waiting one of a random or pseudo random amount of time.

Abstract
It is presented a method for transmitting lighting device data. The method comprises the steps of obtaining, in a lighting device, a subset of lighting device data, the lighting device data containing information of the lighting device, transmitting, from the lighting device, using light, the subset of lighting device data, and repeating the above steps until all subsets jointly corresponding to the complete lighting device data have been transmitted. A corresponding lighting device and lighting system are also presented.

7. A lighting system comprising at least one lighting device, comprising:
-
a data source; a light emitter; wherein the light emitter is configured to obtain a plurality of subsets of lighting device data from the data source; the plurality of subsets jointly corresponding to the complete lighting device data; the emitter further configured to transmit embedded in illumination light each of the plurality of subsets of lighting device data individually; wherein the light emitter further is configured to transmit each subset of the plurality of subsets of lighting device data with a predetermined amount of time between each subset upon obtaining each subset from the data source and to wait a random amount of time after all the plurality of subsets of lighting device data are transmitted; a receiver, wherein the receiver is configured to; receive the subsets of lighting device data jointly corresponding to the complete lighting device data, transmitted from at least one of the at least one lighting devices, processing the received subsets of lighting device data to obtain the complete lighting device data to receive information from at least one of the at least one lighting devices. - View Dependent Claims (8, 9)
