Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp manufacturing technology, specifically relating to a halogen lamp with a lamp holder and wires that do not require soldering. Background Technology

[0002] Halogen lamps are high-efficiency incandescent lamps based on the halogen tungsten cycle principle. Their core structure includes a quartz glass shell, a tungsten filament, and halogen gas. When the filament is energized, it emits light at high temperatures. The evaporated tungsten combines with the halogen gas to form tungsten halide, which is then re-deposited on the filament surface through a cycle, thereby slowing down tungsten filament wear and improving luminous efficiency. Their compact size, high brightness, and color temperature stability make them widely used in automotive headlights, industrial lighting, and other fields.

[0003] There are many types of halogen lamps. Some halogen lamps consist of a bulb, a lamp holder, and a lamp base. Some bulbs have one filament, while others have two filaments. A bulb with one filament has two leads, while a bulb with two filaments has four leads. The leads of the bulb need to be electrically connected to the lamp holder. When the bulb has two leads, the two leads are directly soldered to the metal plate on the lamp holder, and the metal plate is insulated from the lamp holder. When the bulb has four leads, two leads are soldered to the metal plate in the same way, while the other two leads are usually connected in parallel with a wire and then soldered downwards to the bottom of the lamp holder. When soldering the wire to the bottom of the lamp holder, it often requires drilling holes in the lamp holder and soldering, which inevitably prolongs the processing cycle. Moreover, any welding defects will lead to product defects.

[0004] In view of the above, it is necessary to design a halogen lamp that reduces processing steps and eliminates the need for soldering the lamp holder to the wires. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this context. Utility Model Content

A pair of metal plates are insulated and fixed to the lower end of the lamp holder. The filament lamp holder I and the second filament lamp holder I are respectively soldered and fixed to the metal plates. The key feature is that the lower ends of the second filament lamp holder II and the first filament lamp holder II are respectively soldered and fixed to a wire. One end of the wire is bent upwards and clamped between the bulb and the lamp holder to achieve a fixed connection with the lamp holder, and the end of the wire does not protrude from the lamp holder.

The lower end of the lamp holder 2 is insulated and fixed with a pair of metal plates 23. The filament lamp holder I111 and the second filament lamp holder I121 are respectively soldered and fixed to the metal plates 23.

[0022] The technical innovation of this utility model is as follows: the lower ends of the second filament lamp holder II122 and the first filament lamp holder II112 are respectively welded and fixed on a wire 14. One end of the wire 14 is bent upward and clamped between the bulb 1 and the lamp holder 2 to achieve a fixed connection with the lamp holder 2, and the end of the wire 14 does not protrude from the lamp holder 2.

[0023] Please see Figure 1 The bulb 1 contains a first filament 11 and a second filament 12 spaced apart. One end of the first filament base I 111 and the first filament base II 112 are connected to both ends of the first filament 11, and one end of the second filament base I 121 and the second filament base II 122 are connected to both ends of the second filament 12. The first filament base I 111, the second filament base I 121, the second filament base II 122, and the first filament base II 112 are arranged sequentially from left to right, with their lower ends extending downwards out of the bulb 1. The middle portions of the first filament base I 111, the second filament base I 121, the second filament base II 122, and the first filament base II 112 are fixedly connected inside the bulb 1 by a base connecting post 13. The first filament base I 111, the second filament base I 121, the second filament base II 122, and the first filament base II 112 are molybdenum rods. The first filament 11 and the second filament 12 are tungsten filaments. The lamp base connecting post 13 is a quartz glass post.

[0024] Please see Figure 2 The metal sheet 23 has a pair of metal sheet solder joints 231 respectively, and the metal sheet 23 has a contact boss 232 protruding downward from the middle.

[0025] Please continue reading. Figure 1 The lamp holder 2 forms a lamp holder cavity 21 facing upwards. The bulb 1 has a first filament lamp foot I 111, a second filament lamp foot I 121, a second filament lamp foot II 122, and one end of the first filament lamp foot II 112 is inserted into the lamp holder cavity 21 from top to bottom and fixed.
