A gas discharge lamp device and its assembly method

Abstract

The invention discloses a gas discharge lamp device and an assembly method of the gas discharge lamp device. The gas discharge lamp device comprises a discharge tube, a lamp base, a metal supporting component and a wire component, wherein the metal supporting component is fixed on the lamp base, and is used for supporting the near end of the discharge tube, and the wire component forwards extends out of the lamp base from the side of the discharge tube, and is used for supporting the far end of the discharge tube. The metal supporting component comprises a tube clip and a lamp holder, wherein the tube clip is constrained on the discharge tube, the lamp holder is fixed on the lamp base, the tube clip is provided with a pair of folded portions which are opposite to each other and protrude outwards, clamping jaws which extend forwards are distributed on the front portion of the lamp holder in a spaced and circumferential mode, a supporting piece is arranged between every two adjacent clamping jaws, the height of each supporting piece is smaller than that of the end of each clamping jaw, the folded portions of the tube clip are attached to the supporting pieces, and the clamping jaws are welded to the tube clip. According to the technical scheme, light source location of the gas discharge lamp device is easy, operation can be accomplished through a simple device, the gas discharge lamp device and the assembly method of the gas discharge lamp device have the advantages of being high in assembly accuracy and efficiency, and the manufacturing cost of the gas discharge lamp device can be reduced.

Description

technical field [0001] The invention belongs to the technical field of lamps for vehicles, and relates to a discharge lamp device, in particular to a gas discharge lamp device equipped with an arc tube and an assembly method thereof. Background technique [0002] Car lights need the reflection of the lamps to distribute the light accurately, which requires the precise positioning of the light source of the bulb itself. At present, one way of positioning the light source of the discharge lamp device is to perform three-dimensional positioning by means of a high-precision machine tool. However, the cost of equipment required in this way is relatively expensive, and it is difficult for small and medium-sized auto parts factories to apply it. [0003] In addition, Chinese invention patent application publication number 1222749 discloses a discharge lamp device. In the discharge lamp device, it includes an arc tube fixing belt and a ring-shaped metal slide plate. The arc tube fi...

AI Technical Summary

Problems solved by technology

In this structure, since the ring-shaped metal slide plate and the metal base plate are sheet-like planar structures, it is required that the two are very tightly bonded when welding, and at the same time, there should be no deformation under pressure between the metal parts that cooperate with each other, otherwise there will be a slight fit. Lack of tightness or deformation will prevent the arc tube from being perpendicular to the reference plane, resulting in a shift in the position of the light source

However, it is not easy to fit two sheet-like plane objects tightly and ensure no deformation when welding. Therefore, the discharge lamp device has the disadvantage that the position of the light source is difficult to accurately locate, and the discharge lamp device has a defective rate in actual production. very high

[0004] In addition, in the discharge lamp device, the lead wire of the arc tube and the wire are spot welded together, and the welding position is relatively fragile, and the problem of disconnection and separation of the lead wire of the arc tube and the wire is prone to occur, so that the damage rate of the discharge lamp device is relatively high
