Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp production technology, specifically relating to a motorcycle halogen lamp structure that facilitates filament position adjustment. 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. Its compact size, high brightness, and color temperature stability make it widely used in automotive headlights, industrial lighting, and other fields.

[0003] The M5 halogen lamp is a type of motorcycle headlight. It is typically glued directly to a halogen lamp holder (usually a sleeve structure), with the lamp base connected to the holder and an insulating metal plate mounted on it. In use, the lamp base and metal plate are connected to the motorcycle's power outlet. The halogen lamp receives current from the motorcycle battery through the outlet, which heats the tungsten filament to incandescence, emitting light. However, the motorcycle's power outlet fixes the halogen lamp's position, and the filament position cannot be guaranteed to remain consistent throughout the manufacturing process. Therefore, even motorcycles of the same model often experience light scattering and poor focusing due to inconsistencies or misalignments in the filament position, affecting lighting performance and potentially posing safety hazards.

[0004] In view of the above, it is necessary to design a motorcycle halogen lamp structure that is simple in structure, low in cost, and allows for easy adjustment of the filament position. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0005] The objective of this invention is to provide a motorcycle halogen lamp structure that facilitates adjustment of the filament position. This structure helps improve the connection between the halogen lamp and the lamp holder, allowing the halogen lamp to be adjusted on the lamp holder to keep the filament position consistent. This, in turn, helps maintain a consistent illumination angle and improves the lighting effect.

[0006] The present invention achieves its objective as follows: a motorcycle halogen lamp structure for easy filament position adjustment, comprising a lamp body and a lamp body mount for mounting the lamp body. The lamp body mount is cylindrical, with a pair of metal plates insulated and fixed at the bottom of the cylinder. The lamp body is electrically connected to the lamp body mount and the pair of metal plates. The key feature is that an adjusting sleeve is fitted and fixed on the lamp body. The upper part of the lamp body mount has an opening with an inner diameter larger than the diameter of the adjusting sleeve. The lamp body mount is fitted onto the adjusting sleeve, allowing the adjusting sleeve to swing within the lamp body mount. At least two welding windows are spaced apart along the circumference of the outer wall of the lamp body mount. A welding foot connected to the lamp body mount is located near the center of each welding window. By swinging the adjusting sleeve within the lamp body mount, the position of the filament inside the lamp body is changed, and the filament is adjusted to the desired position. The welding foot is then spot-welded to the adjusting sleeve for fixation.

[0007] In a specific embodiment of this utility model, the lamp body is provided with a first filament and a second filament spaced apart front to back, a first filament lamp base I and a first filament lamp base II connected to the first filament, and a second filament lamp base I and a second filament lamp base II connected to the second filament.

The middle parts of the first filament lamp base I, the second filament lamp base I, the second filament lamp base II and the first filament lamp base II are fixedly connected in the lamp body by a lamp base connecting post. The lower ends of the second filament lamp base II and the first filament lamp base II are respectively connected in parallel with a nickel wire. The nickel wire is welded and fixed to the lamp body base. The lower ends of the first filament lamp base I and the second filament lamp base I are respectively welded and fixed to two metal sheets.

[0008] In another specific embodiment of this utility model, an insulating base is fixed to the bottom of the lamp holder, the metal sheet is fixed to the lower side of the insulating base, and a lamp holder welding point is also provided at the bottom of the lamp holder.

[0009] In another specific embodiment of this utility model, a pair of lamp holder positioning plates extend from both sides of the outer wall of the lamp holder.

[0010] In another specific embodiment of this utility model, the first filament lamp holder I, the second filament lamp holder I, the second filament lamp holder II, and the first filament lamp holder II are molybdenum rods.

[0011] In another specific embodiment of this utility model, the first filament and the second filament are tungsten filaments.

[0012] In a further specific embodiment of this utility model, the lamp base connecting post is a quartz glass post.

[0013] In a further specific embodiment of this utility model, the size of the welding foot is smaller than the size of the welding window, the upper edge of the welding foot is connected to the lamp holder, and a welding foot solder point is provided in the middle of the welding foot.

[0014] In yet another specific embodiment of this utility model, metal sheet solder joints are respectively formed on the metal sheet.

[0015] The present invention has the following advantages due to the above-mentioned structure: By adding an adjusting sleeve between the lamp body and the lamp body base and fixing them one by one with welding feet, the position of the filament in the lamp body can be adjusted by swinging the adjusting sleeve to keep the position of the filament consistent. This helps the halogen lamp to maintain a consistent illumination angle and improve the lighting effect, thereby ensuring the correct illumination angle and range of the light and greatly protecting driving safety.
