Description

Description: FIELD OF THE INVENTION The present invention relates to a method of processing a power supply terminal of a halogen lamp with a mirror, and in particular, to a method of processing the power supply terminal in a uniform length and chamfering the tip of the power supply terminal. About.

[Prior Art] Generally, in a halogen lamp with a mirror, a halogen lamp having a power supply terminal extending from a sealing portion is attached to the mirror such that the power supply terminal is exposed outside from an end of the mirror.
In general, the power supply terminal is obtained by welding a second terminal made of a sleeve made of nickel or the like to be inserted into a socket of a lighting device to a tip of a first terminal made of molybdenum.

[Problem to be Solved by the Invention] By the way, as a method of processing the power supply terminal, before mounting the mirror on a mirror, the tip of the first terminal of the halogen lamp itself is covered with a pre-chamfered sleeve of a predetermined length. There are a method of welding and a method of manufacturing a halogen lamp using a rod of a predetermined length in which a front end surface of a power supply terminal is chamfered in advance.

However, in the above case, there is a problem that the length of the power supply terminal exposed from the end of the mirror after being attached to the mirror varies, and a uniform finish of the power supply terminal cannot be expected.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method of processing a power supply terminal of a halogen lamp with a mirror in which the lengths of the power supply terminals are uniform and the ends of the power supply terminals are chamfered.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention focuses on equalizing the lengths of power supply terminals after attaching a halogen lamp to a mirror.

That is, a halogen lamp in which a power supply terminal obtained by welding a second terminal to a tip of a first terminal is extended from a sealing portion, the power supply terminal is exposed to the outside from an end of the mirror, and the halogen lamp is attached to the mirror. This is a processing method in which the power supply terminal is cut to a predetermined length, and the tip of the cut power supply terminal is chamfered by a welding arc.

[Operation] In the processing method of the present invention, first, a second terminal having an arbitrary length is welded to the tip of the first terminal extending from the sealing portion of the halogen lamp. The first terminal and the second terminal constitute a power supply terminal of the halogen lamp. Then, the power supply terminal is exposed to the outside from the end of the mirror, and the halogen lamp is attached to the mirror. At this time, the exposed power supply terminals have different lengths.

Next, the power supply terminal exposed from the end of the mirror is cut to a predetermined length using the end as a reference plane and cut. At this time,
Burr is generated on the end surface of the cut power supply terminal by cutting.

Then, the tip of the power supply terminal is chamfered by a welding arc.

Therefore, the lengths of the power supply terminals exposed from the mirror can be made uniform, and a power supply terminal of a halogen lamp with a mirror having a uniform finish can be obtained.

EXAMPLES Hereinafter, preferred examples of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic sectional view of a halogen lamp with a mirror manufactured by the processing method of the present invention. In FIG.
The halogen lamp 10 is mounted on the mirror 12 with cement or the like, and the power supply terminals 14 and 16 of the halogen lamp 10 are exposed to the length L with the end 12a of the mirror 12 as a reference plane.

In the halogen lamp 10, the lead wire of the filament 18 is connected to the electrodes 22a and 22b made of molybdenum foil of the sealing portion 20. The first terminal 14a is connected to the electrode 22a, while
The first terminal 16a is connected to the electrode 22b and extends from the sealing portion 20. A second terminal 14b of nickel or the like is welded to the tip of the first terminal 14a, while a second terminal 16b of nickel or the like is similarly welded to the tip of the first terminal 16a, Both are exposed outside from the end 12a of the mirror 12.

Next, a method of processing the power supply terminal of the halogen lamp with a mirror will be described with reference to FIGS.

FIG. 2 is a schematic view of the halogen lamp 10. In FIG. 2, first, of the power supply terminals 14 and 16 extending from the sealing portion 20 of the halogen lamp 10, a first terminal 14a or 16a having an arbitrary length l longer than the length L The second terminals 14b and 16b are welded.

Then, as shown in FIG. 3, the halogen lamp 10 is mounted on the mirror 12 with the second terminals 14b and 16b constituting the power supply terminal exposed to the outside from the end of the mirror. At this time, the second terminals 14b and 16b exposed from the end 12a of the mirror 12 have different lengths, and the end 12a is aligned with the length L using the end 12a as a reference plane and mechanically. Cut into pieces. The cut end surfaces of the second terminals 14b and 16b are shown in FIG.
Burrs as shown in (B) occur, for example,
It makes it difficult to insert into the socket of the lighting fixture.

Therefore, as shown in FIG. 5, the tips of the second terminals 14b and 16b are chamfered by a welding arc, for example, TIG welding which is easy to process. That is, the ends of the second terminals 14b and 16b in the drawing are in a rounded and uniform finished state.

In this way, the length of the power supply terminals (second terminals 14b, 16b) exposed from the end of the mirror 12 can be made uniform, and a power supply terminal of the mirror-equipped halogen lamp having a uniform finish can be obtained.

[Effects of the Invention] As is apparent from the above embodiment, according to the present invention, after attaching the halogen lamp to the mirror, the power supply terminal exposed to the outside from the end of the mirror is cut into a predetermined length, and the cut surface is welded. By chamfering with an arc, the length of the power supply terminal exposed from the mirror can be finished uniformly and aesthetically.
