Problems solved by technology

This phenomenon may be exacerbated by the fact that the PC is not running a real-time operating system, the participating microprocessors are running at different frequencies, and these frequencies may have some tolerance

Embodiment Construction

[0049] With the method proposed here, processing units comprising at least one microcontroller (or correspondingly at least one with a conventional circuit arrangement, that is to say for example with input / output units and / or with memory) can be processed in the assembled state The electronic ballast (EVG) of the processing unit) regulates, prescribes its parameters, eg compensates and / or monitors it.

[0050] At this point, the given parameters include, for example, the transfer of data to the EVG or the activation of data that has arrived at the EVG (eg already stored in the memory of the EVG). This parameterizing process can then include the transmission of control or address signals or (simple) codes, by means of which the EVG can specify the corresponding parameters.

[0051] For example, the compensation unit may explicitly transmit to the EVG those data to be used by the EVG. Examples of such data include:

[0052] - lamp type,

[0053]- the lamp current, perhaps a ...

Abstract

The invention relates to a method for setting an electronic ballast, wherein the electronic ballast and a compensating unit are synchronized, and wherein the electronic ballast is set by means of the compensating unit. Moreover, a corresponding electronic ballast and a compensating unit are provided.

Description

technical field [0001] The invention relates to a method for regulating an electronic ballast, an electronic ballast and a compensation unit. Background technique [0002] For example, at the end of production, electronic ballasts (EVG) for illuminants are compensated and tested to ensure high reliability and high quality of the EVG. [0003] Compensation is preferably performed on the circuit board which has not yet been installed in the housing. This allows fine tuning of individual resistors. This method is relatively expensive since the individual components have to be adjusted in a separate adjustment step before the EVG is installed in the housing and can then be assembled in a separate work step. If an error occurs during the installation, this is usually not noticed because the detection process is already finished. If the testing process is carried out after installation, this is an additional work step, since compensation and testing are interrupted by interveni...
