Definitions

• the present invention relates to a method for adjusting an electronic ballast, with which an electric lamp is operated.
• Electronic ballasts are used to set and operate electric lamps. Since a variety of different lamp types exist, it is also necessary in principle that a relatively large number of electronic ballasts must be provided in order to operate the different types of electric lamps can. In order to reduce this high number of different electronic ballasts, electronic ballasts are known which can be used for a plurality of different lamp types. However, it is necessary that the electronic ballast recognizes as independently as possible, which lamp type is connected and then sets the appropriate operating conditions. Essential here is a precise adjustment, inter alia, the preheating current, the lamp current, the burning voltage and other corresponding operating parameters.
• the present invention is therefore based on the object to be able to provide a method for adjusting an electronic ballast, with which an electronic ballast for a plurality of different electric lamps can be operated and the setting and operation of the electric lamps can be performed very precisely.
• the changed settings are programmed in the electronic ballast, wherein the electronic ballast then returns to normal operation, when the electronic ballast detects a value which is below the threshold and which in comparison to normal operation again typical value of the resistance Lamp filament of the electric lamp and / or a replacement load of the electric lamp characterized. Switching between a normal operation and a secondary operation and thus the changing of settings is carried out by reliable and controllable.
• the changed settings are used by the electronic ballast until further reprogramming is performed during a slave operation.
• the threshold value is at least a factor 2, in particular at least a factor 4, in particular at least a factor 8, in particular at least a factor 10 greater, than a value of the resistance of a conventional lamp filament.
• the threshold value is set to significantly exceed a usual value in the conventional proper operation of an electric lamp.
• the electric ballast operated with the electronic ballast is preferably disconnected from the electronic ballast and a programming lamp electrically connected to the electronic ballast, the value of the resistance of the lamp filament of the programming lamp and / or the value of the Resistance of the replacement load of the programming lamp have a value that is atypical compared to an electric lamp, wherein the values are greater than corresponding threshold values.

• the lower interval limit is formed by the threshold value, which represents an atypical value of this or of these abovementioned resistors (lamp filament and / or equivalent load).
• the upper limit of the interval is formed by such a value, which is below a resistance value of a defective lamp and / or a broken lamp filament. It can thereby be prevented that, when the lamp is defective and / or the lamp filament is broken, a secondary operation of the electronic ballast is undesirably set due to the then detected high resistance value.

Ballast is referred to as normal operation of the electronic ballast. If another second electric lamp is to be operated with the electronic ballast, but which characterizes a different second lamp type and thus requires different settings of at least one operating parameter, then it is necessary that this basic setting of the electronic ballast is changed. This requires that the first settings of the operating parameters be changed and thus the electronic ballast is reprogrammed. Such a change in the first settings of the operating parameters is performed during a secondary operation of the electronic ballast.
• the secondary operation of the electronic ballast is characterized or is set when the electronic ballast recognizes a non-typical compared to normal operation value of the resistance of a lamp filament of the electric lamp and / or a replacement load of the electric lamp.
• the atypical value is characterized in that it is greater than a predefinable threshold value.
• the threshold value is set such that its value does not occur in error-free operation and in particular during normal operation of the electronic ballast, since an electric lamp provided for the actual operation is not formed or produced with lamp filaments and / or equivalent loads having values. which approach or exceed these thresholds.

This value indicates an absolutely atypical value of the resistance of a lamp filament, since in conventional lamps, which are used in operation, the value of the resistance of a lamp filament is from a few to a few tens of ohms.
• the value of the resistance of a replacement load of the electric lamp is detected by the electronic ballast and a normal operation or a secondary operation is set depending on this.
