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, the metal holder is visually very noticeable and greatly influences the transparent appearance known from conventional incandescent bulbs

Embodiment Construction

[0029] 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 an incandescent filament 5 of the built-in lamp 4 is located approximately in the outer bulb 3 at the position where the incandescent filament is likewise arranged in a conventional incandescent lamp. The built-in lamp 4 is implemented as a so-called high-pressure halogen lamp using bulb extrusion technology and is known from the prior art as such a lamp. The built-in lamp 4 is held in two feed lines 6 which are each bent in an S-shape at their built-in lamp-side ends. As a result, a U-shaped bend 7 is formed in each case, in which bend the base 8 of the integral lamp 4 is held.

[0030] exist figure 2The details of this construction can be seen particularly clearly in . Starting from the base 2 of the lamp 1 , the feed line 6 is fi...

Abstract

The invention relates to an electric lamp (1) with 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 (6) from the base (2) to the integral lamp (4), the integral lamp (4) being held on the power supply wires (6). At least one of the power supply wires (6) has, in the region of the end (12) on the integral-lamp side, at least one u-shaped bend (11) for accommodating a base (8) of the integral lamp (4).

Description

technical field [0001] The invention relates to an electric lamp with a single-sided base, with an outer bulb placed in the base and at least one recessed lamp (preferably a high-voltage halogen lamp) arranged in the outer bulb and at least two lamps extending from the base to the A feeder for a recessed light, wherein the recessed light is held on the feeder. 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 la...
