The invention relates to electrical engineering and can be used in the manufacture of thermal sources of optical radiation, in particular incandescent lamps for vehicle headlights.

The aim of the invention is to simplify the adjustment and increase the reliability of the incandescent lamp in transport.

An optical device made in the form of at least one optical fiber with a focusing element, installed along the optical axis 15 of the lamp and additionally inserted into its bulb, was additionally introduced into a car-mounted double-filament automobile filament lamp containing a flask, thread mounting parts and a dipped-beam screen. .

Figure 1 shows the lamp in assembled form; figure 2-4 - the same options; figure 5 - installation diagram of the optical device of the lamp on its flask; 6-10 - the same, option 20; 11 is a schematic diagram of an installation for adjusting the headlights of a vehicle with a lamp.

The lamp consists of bulb 1, base 2, parts 3 for fastening the high beam 4 4 and low beam 5, the screen b for the low beam. On the flask 1 of the lamp is fixed, for example, by the method of surfacing an optical device 7, which is located in the center of the optical axis of the lamp opposite the filament 4 30 high beam. The optical device 7 is made at least in the form of a single fiber, for example, a cylindrical shape of optical glass, on the outer surface of which 35 reflecting coating 8 is applied. The optical device 7 can be made of colored optical glass or colorless optical glass with a light filter 9 installed, for example, by melting at one end of a specified fiber with a focusing lens 10.

In addition, the optical device 7 can be made in the form of a prefabricated fiber 11 of several 45 afofon optical fibers that are interconnected, for example, by melting, the ends of which are located in a plane perpendicular to the optical axis of the lamp.50

Headlight incandescent lamps with tViny distribution. The American beam has a small screen for dipped beam, which is installed on parts of 3 fasteners and does not need additional support points (Figures 1 and 2). Headlamps with light distribution according to the type. The European beam has a large screen 6 dipped-beam, which has additional attachments, namely, stamping 12, for example, of a cylindrical shape, which coincides with the size of the optical fiber of the optical device 7 and is installed on its outer surface (Fig. .4 and 3).

Possible installation of the device on the inner surface of the bulb 1 of the lamp, for example, by welding (figure 1) without the output of the optical device 7 on the outer surface of the bulb 1 or, for example, by the method of melting (figure 5), when the optical device 7 goes to the outer surface bulb 1 through the hole in it, but does not protrude beyond the surface of the bulb 1 of the lamp.

A variant of mounting the optical device 7 on the surface of the bulb 1 is possible, for example, using the zaplavky method, when the optical device 7 is located in the inner and outer parts of the bulb simultaneously and protrudes beyond the surface of the bulb 1 of the lamp (figure 5).

Possible installation of the optical device 7 only on the outer surface of the bulb 1, for example, by surfacing without output of the optical device 7 on the inner surface of the bulb 1 (Fig.7) or with access to the inner surface of the bulb through the hole prepared in it.

The light filter 9 may be located at one of the ends of the optical device 7, for example, by surfacing an optical device 7 on the inner end of the optical fiber 7 (Fig.8-9) or on the outer surface of the bulb (Fig. 10), as well as on the optical end of the optical fiber 7 with a focusing lens 10.

The lamp works as follows.

The optical device 7 of the lamp creates a stream of parallel rays that can be detected when the high beam is turned on. Since the optical device 7 forming the light marker is located in the center of the headlight's luminous flux with sufficient accuracy, it becomes possible to adjust the headlamp on the light spot of the marker on the ruler using adjustment screws by moving the headlight reflectors in the horizontal and vertical directions.
