Problems solved by technology

Mounting clips are placed on the glass base of the outer bulb, however this is very expensive, since the glass base is a very complex part, which includes, for example, the extraction pipe and the integrated power supply lines
In addition, when using metal mounting clips, there is also the risk of damage to the outer bulb when the lamp is installed or when the lamp is in operation, and it must be ensured that no conductive parts are connected to the clip
In addition, the metal holder is visually very noticeable and greatly influences the transparent appearance known from conventional incandescent bulbs

Embodiment Construction

[0024] figure 1 The lamp 1 according to the invention is shown in a perspective view. An outer bulb 3 of model A55 is held in a lamp cap 2 of model E27 which is common on the market. A built-in lamp 4 is arranged in the outer bulb 3 such that a filament (not shown here) of the built-in lamp 4 is located approximately in the outer bulb 3 at a position in the outer bulb 3 where a filament is likewise arranged in a conventional incandescent lamp. The built-in lamp 4 is embodied as a high-pressure halogen lamp and is known from the prior art as such a lamp.

[0025] The built-in lamp is held in a cylindrical bulb 5 which widens in the lower region 6 and is fused to the outer bulb 3 . This enables a simple and safe connection of the outer bulb 3 and the bulb 5 , which are made of the same material (in this embodiment soft glass as is common in bulb manufacturing).

[0026] The lower region 6 and the middle region 7 of the bulb 5 have a cylindrical shape, while the upper region 8...

Abstract

The invention relates to an electric lamp with external bulbs and embedded bulbs arranged in the external bulbs. THe electric lamp (1) has a base at one end and with an outer bulb (3), mounted in a base (2), and at least one integral lamp (4), preferably a high-voltage halogen lamp, which is arranged within the outer bulb (3), and at least two power supply wires (15) from the base (2) to the integral lamp (4). The at least two power supply wires (15) are surrounded by a preferably cylindrical bulb (5), formed from a nonconductive light-permeable material, preferably identical to the material used for the outer bulb (3), in particular glass, and the preferably cylindrical bulb (5) is in the form of a holding apparatus for the integral lamp (4).

Description

technical field [0001] The invention relates to an electric lamp with a single-sided base, having an outer bulb arranged in the base and at least one recessed lamp, preferably a high-voltage halogen lamp, arranged in the outer bulb and having at least two lamps extending from the base to the recessed lamp. feeder for lamps. Background technique [0002] Halogen incandescent lamps are becoming more and more popular than traditional incandescent lamps due to their long life and the quality of light they exhibit. In order to be able to replace existing incandescent lamps with halogen incandescent lamps as simply as possible while maintaining the appearance of conventional incandescent lamps for aesthetic or functional reasons, lamps are generally used in which the outer contour and thus in particular the outer The bulb and lamp base correspond to conventional incandescent lamps, while a halogen incandescent lamp is provided as a built-in lamp in the outer bulb. Such lamps are...
