Patent ID: 8757838

Claim:
A lighting device comprising a plurality of light emitting tiles, each one of the plurality of light emitting tiles having at least one interface, configured for signal transmission, each tile having electrical conductors connected to the at least one interface, the at least one interface being configured to connect two light emitting tiles of the plurality of light emitting tiles with each other by using a connection element, wherein a shape of each light emitting tile is a polygon with at least three sides, each side includes the interface for connecting the light emitting tiles with each other, wherein the plurality of light emitting tiles is connected by means of the at least one interface and connection elements to form a light emitting surface connected by a daisy chain bus system, the daisy chain bus system being adapted for transmitting signals, the signals being indicative of power and/or colour of each light emitting tile, wherein the electrical conductors in each tile of the plurality of light emitting tiles are arranged according to a daisy chain bus scheme, wherein each of the at least one interface comprises a switch, the daisy chain bus of one tile of the plurality of light emitting tiles being closed only if each switch is closed, the switch of the at least one interface being opened when a connection element is connected to the at least one interface, the daisy chain bus of each tile of the plurality of light emitting tiles having one input and one output port per opened switch, the input and the output port being connected to the connection element.
