Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp manufacturing technology, specifically relating to a motorcycle halogen lamp structure with good contact. 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] The M5 halogen lamp is a model used for motorcycle lights. It typically has a pair of metal plates at the bottom that connect to the motorcycle socket when in use. The lamp filament extends to the metal plates and is welded to them. During welding, the solder joint leaves raised solder on the metal plates. When the halogen lamp is installed, it contacts the power source through the raised solder on the metal plates or the flat surface of the metal plates. However, this contact method is particularly dependent on the welding quality. When the solder is uneven or there is a cold solder joint, it is very easy for the halogen lamp to have poor contact. Moreover, the solder is particularly easy to break under pressure or high temperature, which affects its service life.

[0004] In view of the above, it is necessary to design a motorcycle halogen lamp structure that is simple in structure, easy to manufacture, and provides good contact during installation. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content
