Problems solved by technology

[0005] Disadvantages of this type of bulb are, on the one hand, that the joining technology between the halogen built-in bulb and the lamp holder can only be automated to a certain degree due to welding technology, and, on the other hand, that the halogen built-in bulb connected to the lamp holder has a greater overall height and lower cold impact strength
Although this solution allows installation of the bulb without fusion technology, it is at the expense of an expensive multi-section construction and a greater overall height of the lamp
Furthermore, visible adapters do not meet the high demands placed on popular bulb designs

Embodiment Construction

[0042] first according to Figure 1 to Figure 7 An embodiment of the bulb 1 of the invention is illustrated, which has the design of a conventional incandescent lamp, but emits halogen light.

[0043] The bulb 1 has a built-in bulb 2 , which is mechanically and electrically connected to a lamp socket 6 via a connecting element 4 and is surrounded by a bulb housing 8 . The bulb envelope 8 used can have various bulb envelope shapes known from the prior art (eg droplet, candle, mushroom, etc.), or it can be made in the form of a tubular bulb. Depending on the application, roughened, transparent or siliconized or partially siliconized glass envelopes can be used to increase the scattering effect. In the exemplary embodiment shown, the connection part 4 is produced in such a way that it can be contained substantially completely in the space enclosed by the bulb envelope 8 and the lamp base 6 .

[0044] In the exemplary embodiment shown, the built-in bulb 2 is produced as a conven...

Abstract

A light bulb is disclosed, the built-in bulb of which is electrically and mechanically connected to a lamp socket through a connecting part. The connection part is preferably produced in the form of a clip and is substantially completely surrounded by the lamp base and the bulb housing, so that the bulb can have the shape of a conventional incandescent bulb and the connection part visually enters the background, so that high aesthetic requirements can also be met .

Description

technical field [0001] The invention relates to a light bulb with a built-in bulb according to the preamble of claim 1 , a connection part according to the preamble of claim 8 and a method of manufacturing a light bulb according to the preamble of claim 20 . Background technique [0002] Halogen incandescent lamps (bulbs) are increasingly used in many fields of daily life due to their good luminous quality and long life. In applications where aesthetics and economy are critical, it is also desirable to replace conventional incandescent bulbs driven with mains voltage by halogen incandescent bulbs. Accordingly, bulbs have been developed with built-in halogen incandescent bulbs, which are surrounded by a bulb envelope and are thus visually indistinguishable from conventional incandescent bulbs. [0003] Internet domain name www.osram.de Indicated under the product name "HALOLUX(R) CLASSIC". In this bulb, a single-side pressure-sealed halogen built-in bulb is held by a clip ...
