Problems solved by technology

Therefore, when the connection point of the spacer is on one side of the rotation axis of the hook connecting the spacer, and the connection point of another spacer is on the other side of the rotation axis of the hook connecting the spacer, it is difficult to fit the filament in the lamp
[0008] However, even if the two struts are asymmetrical, a similar problem arises when the two connection points are on the same side of the two axes of rotation of the hook on the metal strut
[0009] This situation makes the assembly time quite long and may damage the filament

Embodiment Construction

[0019] attached Figure 1a and 1b A prior art lamp is shown. The problem solved by the invention can be seen from the description of such a lamp.

[0020] This lamp comprises a first filament part 100, a second filament part 101, a first auxiliary part 102, a second auxiliary part 103, a first spacer 104, a second spacer 105, a first Metal support bar 106 , second metal support bar 107 including second hook 107 a , bridges 120 and 121 connected by metal bars 122 and 123 , spacer 124 , and filament ring 125 . The first filament part 100 has a first rotation axis 110 , and the second filament part 101 has a second rotation axis 111 . The axes of rotation of the hooks 106 a and 107 a substantially coincide with the first axis of rotation 110 and the second axis of rotation 111 . It will be considered below that the axis of rotation of the first hook 106 a is the first axis of rotation 110 and the axis of rotation of the second hook 107 a is the second axis of rotation 111 . T...

Abstract

The invention relates to the field of lamps. An electric incandescent lamp comprises a filament comprising a portion (100) comprising coils disposed in a spiral around an axis of revolution (110), and a secondary part (102) connected to said portion by means of a spacer (104), as well as a metal current supply rod (106), the secondary part being attached to the metal rod by means of the spacer. In order to facilitate the assembly of such a filament in the lamp, that is to say the attachment of the filament to the metal supply rod, the spacer comprises at least two coils stretched in a direction parallel to the axis of revolution of said portion.

Description

technical field [0001] The invention relates to an incandescent electric lamp comprising at least: [0002] a filament comprising at least one portion comprising a coil arranged helically about an axis of rotation, and an auxiliary portion connected to said portion by means of a spacer; [0003] A metal current supply rod to which the auxiliary part is connected by means of spacers. [0004] Such lamps can also be used eg in stage lighting systems. Background technique [0005] Applicant markets this lamp under the 6995Z standard. In such lamps, the filament consists of several parts which lie in two planes. Two metal rods are electrically connected to the two filament parts and to an external circuit so that the lamp can be supplied with electric current. The two metal rods have a hook at one end thereof, which is oriented around the axis of rotation, and the two metal rods are also electrically connected to the two filament parts by means of two spacers, the two spacer...
