This results in that in the inserted state, in which the contact pins 8th engaged in the contact receptacles of the lighting unit, the device 1 within the contact receptacles is rotatable about its longitudinal axis. The device 1 can then be aligned around the axis of rotation that the Umrüstleuchtmittel 2 one for the radiation optimal position occupies.

2a shows a further improved device according to the invention 9 for the conversion of lighting units intended for fluorescent lamps with two-sided contacts from inductive to electronic operation with an electronic ballast 10 and at least one conversion bulb 11 ,

According to the invention, the device 9 a support element 12 on, as well as on this attachable holding elements 13 , The holding elements 13 are for example in the form of plastic clips on the support element 12 snap-on or in any other suitable manner on the support element 12 fixable.

The holding elements 13 have not provided with a reference numeral contact socket, with which the lateral contact pins 14 the at least one Umrüstbeluchtmittels 11 can be brought into engagement. The conversion light 11 is through the contact socket of the retaining elements 13 on the one hand mechanically to the support element 12 On the other hand, this will be the reason for the operation of the Umrüstleuchtmittels 11 required electrical connections between this and the electric ballast 10 and between this and a suitable electrical power supply - not shown - produced.

As already described above, the contact pins 16 attached to adapters which are at the ends of the support element 12 are attached and about the longitudinal axis of the support element 12 are rotatable. In the state in which the contact pins 16 engage in the contact receptacles of the lighting unit, the support element 12 then be rotated about its longitudinal axis so that the conversion illuminant 11 can be aligned in a favorable radiation position.

For a secure mechanical support of the at least one Umrüstbeluchtmittels 11 on the support element 12 can the device 9 , especially for longer conversion lamps 11 , one or several support elements 15 exhibit. These can for example also be designed as plastic clips.

To convert a - not shown - lighting unit to be replaced - not shown - light source is removed from the lighting unit and instead the device 9 used in the retrofitted lighting unit. Here are the lateral pins 16 of the support element 12 with the corresponding - not shown - contacted contacts of the lighting unit engaged. In this way the device becomes 9 mechanically held in the retrofitted lighting unit and it will be for the operation of the device 9 required electrical connections between the corresponding components.

How out 2 B The retaining elements are visible 13 slidable on the support element 12 arranged. This can be achieved by simply moving the retaining elements 13 along the longitudinal axis of the device 9 the distance between two retaining elements 13 be changed and thus a Umrüstleuchtmittel 11 different length are used. This increases, as already stated, the design freedom in the conversion of lighting units.

2c shows a possibility of several conversion lamps 11 on the support element 12 to arrange, then correspondingly more holding elements 13 and support elements 15 be used.

round 70% of all fluorescent lamps in use become worldwide still operated electromechanically. That means they will operated inductively with a ballast (choke). The simple conversion to ECG by means of an adaptive system to take without intervention in the lighting technology is not yet been possible. At the same time there is no adaptive conversion variant which corresponds to the state of the art.

The ECG shown here is specially designed for use in the retrofit area developed the electromechanical linear luminaires. It is through its developed design and the purpose accordingly very flat and narrow, causing the length opposite commercial ECG increases.

There are electronic ballasts as adapters or kit solutions for the conversion of inductance to capacity by means of electronic ballast, which do not correspond to the prior art. These systems interfere with existing electrical engineering by using so-called jumper or bypass adapters with and without a resistor and fuse. That is, they remove the starter of the lamp and replace it with a foreign object of the origin. As a result, an intervention in the technology of the lamp is made and thus loses the electrotechnical approval. The system shown here works without these additional components. The system presented here incorporates the entire technology in its form. For operation, only the starter is removed.

The electronic ballast developed here is replaced by the electromechanical ballast remaining in the existing luminaire 31 provided. The ECG can also be supplied directly with mains voltage and also works without an upstream ballast. The electronics work with all common mains voltages and mains frequencies worldwide such. Eg 110/120/230/240 V, 50/60 Hz.

Advantageous is a filter technology, which makes it possible to use this according to the prior art both in series and parallel compensated lights. In addition, an EMC filter module 32 switched, which is adapted to the conversion system.

Depending on the local environment and the type of compensation in the electromechanical luminaire, the power factor (power factor) is intelligently controlled (by the reference numeral 33 provided modification unit), so that the system according to the current state of the art automatically reaches the value of the PF (= Power Factor, cos (φ)) of 0.99.

Software and control are preferably developed for the type of conversion. A regulation by microcontroller 34 is missing in other adapter solutions entirely.

The conversion system shown here is adjustable in brightness. On the housing of the adaptive Umrüstsystemleuchte shown here, an interface 35 be mounted, which makes it possible to regulate individual luminaires or by a connecting line several lights in groups in terms of brightness.

The Components or the circuit can be integrated on the PCB of the ECG be connected upstream of the ECG as an external module.

The System shown here is available as a multifunction system with the possibility several power classes of the T5 fluorescent lamp to use (z. B. 14/28/35 W).

The System works in contrast to adapter solutions and multi-lamp operation.

The electronic ballast shown here was specially developed for these applications and preferably has the following technology:
EMC filter adapted to inductive ballasts
EMC filter for RF interference
Filtering with local compensation (parallel or series compensation)
PFC / Automatic correction of the power factor / correction of the network harmonics
HF half-bridge generator with resonance circuit
EOL / End of Live circuit as safety shutdown
storage capacitor
Overvoltage protection
Automatic restart after lamp change
Digital ASIC technology
Microcontroller for control and monitoring
Automatic lamp detection

In the 5 shown arrangement shows an example of a circuit arrangement of a dimmable fluorescent lamp assembly. Here, at the entrance of the circuit is a filter device 40 arranged to have a retroactive effect on a network feeding the arrangement 46 to prevent. By means of a rectifier arrangement 41 a supply voltage is rectified. This rectified voltage is used by the inverter 42 as input voltage. The inverter converts the input voltage according to the specifications of the light control module 43 , in an output voltage of variable frequency (for example, from 28 kHz to 45 kHz) and possibly variable amplitude to. By means of the voltage thus converted becomes a light source 44 (or a group of bulbs) fed, which can then be operated in different brightness states.
