The outer bulb 2 is here cut open along its cross section, so that the left side L of the outer bulb of the outer shape of the line lamp retrofit lamp 1 corresponds and the right side R shows the inserted or arranged in the outer bulb elements. The line lamp retrofit lamp 1 is a type S14s with two laterally protruding, single-pole contacts 3 equipped, of which only the left contact 3 is shown.

As shown on the right R, are located in the outer bulb 2 A carrier 4 , one on a top 5 of the carrier 4 attached fluorescent lamp 6 , z. B. type T2 or T5, as well as an electronic ballast 7 for the operation of the fluorescent lamp 6 , The electronic ballast 7 includes a printed circuit board 10 that come with electronic components 11 is equipped. The electronic ballast 7 can be a warm start ECG. The carrier 4 is elongated in shape and lies parallel to the outer bulb 2 , The fluorescent lamp 6 lies parallel on the support 4 on. The electronic ballast 7 is partly in the carrier 4 inserted and partially protrudes above the right contact, not shown here from the carrier 4 to allow easy electrical contact with the contact.

During operation, the electronic ballast supplies power 7 the fluorescent lamp 6 and will even about the contacts 3 fed. The fluorescent lamp 6 has a radially uniform with respect to their longitudinal axis of light emission and thus also illuminates the carrier 4 at. To increase the luminous efficacy, the carrier can 4 or in particular its top 5 be reflective designed to the light falling on him through the outer bulb 2 to reflect to the outside. The reflective structure may be formed by a corresponding coating or by a surface treatment (polished surface or the like in a metallic support 4 ), or by providing a separately prepared reflector. The reflective embodiment can also be used, in particular, for end areas 8th of the outer bulb 2 more illuminate and thus to achieve a particularly extensive reproduction of the emission characteristics of a conventional line lamp.

To provide visibility of the electronic ballast 7 through the outer bulb 2 through is the electronic ballast 7 executed in one color, z. B. painted, which at least approximately the color of the outer bulb 2 corresponds, here: white.

For the production of the line lamp retrofit lamp 1 an open at both ends of the cylinder tube is taken, which is also used to produce a conventional line lamp. Thus, to manufacture the line lamp retrofit lamp 1 also conventional parts continue to be used. In the cylinder tube are at least the fluorescent lamp 6 and the electronic ballast 7 which have been previously assembled into a unit introduced. In a subsequent step, for example, the electronic ballast 7 through the introduction of the lateral contacts 3 provided openings are contacted by means of at least one contact wire. The carrier 4 or the electronic ballast 7 can be equipped with a contacting aid. Thereafter, the two open ends of the cylinder tube are sequentially closed by a fusion process to the Außenkoben 2 to build. To avoid, in particular, the wearer 4 and / or the electronic ballast 7 can be thermally damaged in the fusion, the carrier 4 and with it the fluorescent lamp 6 and the electronic ballast 7 be lifted by the contact wire from the cylinder tube and kept free in the cylinder tube. Is the resulting outer bulb 2 cooled sufficiently, becomes the carrier 4 through the at least one contact wire to the outer bulb 2 used and thereby fixed.

The finished line lamp retrofit lamp 1 can be installed in existing line lamp luminaires without conversion. Outwardly is the line lamp retrofit lamp 1 not from a regular line lamp 1 to distinguish. An energy saving of up to 80% is achieved. The EuP directive is fulfilled, whereby an energy efficiency class A is possible. By choosing different fluorescent lamps 6 Different colors of light are possible, for. B. in the range between 2700 K to 8000 K. There are lengths up to 1000 mm easily possible. It is achieved compared to incandescent line lamps long life of 8000 h instead of previously only 1000 h. Since no plastic piston, but a glass flask is used, a noble appearance is achieved, and it can be used conventional glass flask. The line lamp retrofit lamp 1 is 1: 1 interchangeable with a conventional line lamp, such as a Linestra lamp from Osram. On a sample lamp, an efficiency of about 60 lm / W at a color temperature of about 3000 K and a Ra of about 80 was measured.
