Abstract
A light emitting device (100) for emitting a beam of light is disclosed. The light emission of the light emitting device (100) comprises an embedded code. The light emitting device (100) comprises a beam shape controller (102) for controlling a shape of the beam of light and a first processor connected to the beam shape controller, arranged for generating the embedded code. The first processor (104) is further arranged for embedding a message in the embedded code based on the shape of the beam of light. This allows the light emitting device (100) to communicate information to a receiving device based on its effect area (i.e. the illuminated area). This information may, for example, comprise information about the beam shape and size, which may be used to determine an area wherein the receiving device is located relative to the light emitting device (100).
