Single-ended halogen lamp with supporting frame locating hook

Abstract

The invention provides a single-ended halogen lamp with a supporting frame locating hook. The single-ended halogen lamp with the supporting frame locating hook comprises a lamp filament supporting frame, molybdenum sheets, a bulb shell and a lamp filament, wherein a molybdenum pin is welded to each molybdenum sheet, the lamp filament supporting frame, the molybdenum sheets and the lamp filament are respectively placed in the bulb shell. The number of the molybdenum sheets is two and the two molybdenum sheets are located in the clamping flat positions of the bulb shell. The molybdenum pin of each molybdenum sheet extends out of the bulb shell. One end of the lamp filament supporting frame is bended in the width direction of the bulb shell, so that a lamp filament hook used for supporting the lam filament is formed. One end of the lamp filament is hung on the lamp filament hook, and the other end of the lamp filament is downwards welded to one molybdenum sheet. The other end of the lamp filament supporting frame is welded to the other molybdenum sheet. The end, welded to the other molybdenum sheet, of the lamp filament supporting frame is bended in the welding portion between the end and the molybdenum sheet in the width direction of the bulb shell, so that the locating hook is formed. The locating hook and the lamp filament are on the same plane. By the adoption of the locating hook, after the lamp filament supporting frame is welded to one molybdenum sheet and clamped to the bulb shell in a sealed mode, the lamp filament hook and the lamp filament are both located in the middle of the thickness of the bulb shell. The single-ended halogen lamp with the supporting frame locating hook has the advantages of being stable in production process, high in quality uniformity, even in light distribution, long in service life and the like.

Description

Technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a single-ended halogen lamp with a supporting frame positioning hook. Background technique [0002] As known in the industry, halogen lamps are also known as tungsten halogen lamps. The principle is to inject halogen gas such as iodine or bromine into the bulb. Under high temperature, the sublimed tungsten wire will react with halogen, and the sublimated tungsten will re-solidify on the tungsten wire, forming a balanced cycle to avoid premature breakage of the tungsten wire Therefore, halogen lamps have a longer life than incandescent lamps. At present, the existing single-ended halogen lamps are due to the insufficiency of the design. Image 6 And Figure 7 As shown, since the filament support frame 01 is a straight pole at the welding point of the molybdenum sheet, when the filament support frame 01 is welded with the molybdenum sheet 02 and is clamped with the bulb 03, th...

AI Technical Summary

Problems solved by technology

At present, the existing single-ended halogen lamps are insufficient in design, such as attached Image 6 And attached Figure 7 As shown, since the filament support frame 01 is a straight pole at the welding place with the molybdenum sheet, when the filament support frame 01 is welded with the molybdenum sheet 02 and clamped with the bulb 03, the filament support frame 01 usually twists and rotates An unfavorable situation occurs at an angle, which causes the filament hook 05 to deviate, causing the filament 04 to deviate from the middle part of the thickness of the bulb 03, as attached Image 6 And attached Figure 7 As shown, this directly leads to the unattractive overall appearance of this type of single-ended halogen lamp, and more importantly, when in use, the light distribution of this type of single-ended halogen lamp is uneven, which may seriously affect the performance of the single-ended halogen lamp. The quality of use will even have a certain impact on the life of single-ended halogen lamps
