Abstract
What is proposed is: an operating device for operating in particular a light-emitting means (12), having: —supply terminals (16, 17) for connecting the operating device to a supply voltage provided by a supply source (20), —output terminals (10) for controlling the light-emitting means (12), —an interface (21) for connection to a bus (2), and—a transmission path which is coupled to the interface (21), wherein the transmission path is designed to connect the received supply voltage to the bus (2) selectively.
Claims21
An operating device for operating especially a light-emitting means (12), comprising
- at least one supply terminal (16, 17) for connecting the operating device to a supply voltage provided by a supply source (20),
- output terminals (10) for controlling the light-emitting means (12),
- an interface (21) for connection to a bus (2), and
- a transmission branch coupled to the interface (21), wherein a control unit of the operating device switches the supplied supply voltage timed to the bus (2) in order to send data to a further operating device, wherein the data are coded to be analog or digital by the timing of the connection of the supply voltage.
An illumination system, having a number of operating devices (3, 4, 5) for operating a light-emitting means (12), wherein
- the operating devices (3, 4, 5) are in each case connected to a bus line (2) via an interface (21),
- in each case have at least one supply terminal (16, 17) for connecting the operating device to a supply voltage provided by a supply source (20), and in each case at least one output terminal (10) for controlling the light-emitting means (12),
- at least one operating device (3) is connected to a sensor (11) via terminals (8, 9) and this operating device (3) has a transmission branch coupled to the interface (21), and
- a control unit of the operating device switches the supplied supply voltage timed to the bus line (2) in order to send data to a further operating device, wherein the data are coded to be analog or digital by the timing of the connection of the supply voltage.
A method for transmitting data via a bus (2) on the basis of a first operating device for operating especially a light-emitting means (12) towards a second operating device, wherein
- the first operating device is supplied by a supply voltage,
- the first operating device switches the supplied supply voltage timed to the bus (2) via a transmission branch, in order to send the data to the second operating device, wherein the data are coded to be analog or digital by the timing of the connection of the supply voltage and
- the second operating device evaluates the supply voltage, connected to the bus (2), via a reception branch.
