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).

A fully-digital distributed scintillation crystal lifting furnace control system includes an upper computer, an intermediate-frequency heating module, a weighing module, and a crystal growth control module. A control module communicates with the weighing module to obtain a weighing signal, the control module communicates with the intermediate-frequency heating module to set a power value and read an intermediate-frequency parameter, the control module communicates with the upper computer to upload a monitoring signal and receive an operating command, and all the communication is digital and greatly improves the control accuracy of the system. The system provided by the invention is designed based on the ideal of a distributed control system. The control module and the upper computer are mutually independent in function, so that crystal growth control can get rid of software of the upper computer and normally proceed, and hidden danger brought by faults of the upper computer is prevented. Meanwhile, one upper computer can be connected with multiple lower computer control modules, so that crystal growth can be monitored in a more concentrated manner, and equipment and manpower costs are reduced greatly.
