Embodiment Construction

[0028] Such as figure 1 As schematically shown in, according to the present invention, a control signal is applied to at least one input side terminal 1 and 2 of the interface circuit 12.

[0029] Although two terminals 1, 2 for bus pairs or for buttons / switches are shown in the exemplary embodiment, it should be emphasized that the present invention also finds applications for interfaces for connecting single signal lines.

[0030] The control signal may be, for example, a digital signal (for example according to the DALI standard) or a signal from a button / switch. An evaluation logic 3 is provided in the interface circuit 12, which converts the control signal transmitted to the input-side terminals 1 and 2 into a control signal for the ballast electronic device 13. These converted signals are transmitted from the evaluation logic 3 to the ballast electronic device 13 through the electrical coupling of, for example, an optocoupler or a transformer, so that the ballast electronic...

Abstract

The device has at least one input connection (1,2) for connecting bus lines or for connection to a button and / or switch, evaluation logic (3) for processing signals applied to the input connection and for generating output signals for controlling the lamp operating unit and at least one electrical isolation element (4) for decoupling the input connection from the operating unit. The logic is arranged on the side of the isolation element towards the at least one input element. Independent claims are also included for the following: (A) a lamp operating unit (B) and a method of controlling a lamp operating unit via an interface.

Description

Technical field [0001] The invention generally relates to interfaces for lamp operating devices, such as electronic ballasts for gas discharge lamps. The present invention further relates to a lamp operating device having such an interface, and a method for controlling the lamp operating device by means of the interface. Background technique [0002] Through such an interface, a signal can be transmitted to the lamp operating device from the bus or from a button or switch connected to the power supply voltage. Therefore, an evaluation logic is usually provided in the interface, which converts the digital or analog signal appearing at the interface input into a control signal for the lamp operating device. The signal transmitted to the interface can represent commands (ideal values ​​such as setting values) and can also represent information related to conditions. In particular, if a bidirectional interface is provided, the condition information from the lamp operating device can ...
