Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp production technology, specifically relating to a vibration-resistant halogen lamp. 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] When halogen lamps are used in car and motorcycle lights, especially when driving in bumpy environments, the lamp arm and filament inside the bulb are particularly prone to vibration, causing the light beam to flicker. However, because the fluctuation is very small, it has not attracted much attention from industry professionals. But as the size of halogen lamps increases, the length of the lamp arm and filament also increases, and the flickering of the beam becomes more severe. Repeated vibrations not only cause metal fatigue in the lamp arm and filament, reducing their lifespan, but also make the direction of the beam unstable, resulting in flickering or brightness fluctuations. This greatly affects the lighting effect and driving safety during driving.

[0004] In view of the above, it is necessary to design a vibration-resistant halogen lamp that is simple in structure, low in cost, and can effectively reduce the vibration of the lamp post. 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 vibration-resistant halogen lamp that helps improve the lamp post fixing structure to avoid lamp post vibration and thus filament vibration. This significantly reduces the vibration frequency and amplitude of the lamp post and filament in bumpy environments, effectively improving the service life of the lamp post and filament, as well as the stability of the beam, and greatly enhancing safety during driving.

[0006] The present invention accomplishes its objective as follows: a vibration-resistant halogen lamp includes a lamp body, at least one filament disposed within the lamp body, at least one first lamp post connected to one end of the filament, at least one second lamp post connected to the other end of the filament, a pair of molybdenum sheets disposed within the lamp body, and a pair of lamp feet connected to the molybdenum sheets and extending out of the lamp body. The lamp body is characterized by a horizontally arranged lamp post fixing column, which is fixed to the first and second lamp posts by high-temperature welding. Both ends of the lamp post fixing column extend laterally and contact the inner wall of the lamp body. The lamp body is made of quartz glass, and during its molding process, it is formed into a single unit by high-temperature welding with both ends of the lamp post fixing column.

[0014] In another specific embodiment of this utility model, the number of filaments is one, and correspondingly, the number of the first lamp post and the second lamp post is also one. The filament is arranged vertically and its two ends are welded and fixed to the upper ends of the first lamp post and the second lamp post, respectively. At this time, the first lamp post and the second lamp post are arranged in a state of one short and one long, and the filament is arranged above the first lamp post.

[0015] In yet another specific embodiment of this utility model, there are two filaments, and correspondingly, there are also two first lamp posts and two second lamp posts.

At this time, the height of the first lamp post and the second lamp post are the same, and the filaments are arranged between the corresponding first lamp post and the second lamp post.

[0016] The present invention has the following advantages due to the above-mentioned structure: By adopting the structure of connecting the lamp post and the lamp body with the lamp post fixing column, the lamp post, lamp post fixing column and lamp body are formed as a whole, thus avoiding lamp post vibration and filament vibration. This significantly reduces the vibration frequency and amplitude of the lamp post and filament in bumpy environments, effectively improves the service life of the lamp post and filament as well as the stability of the beam, and greatly improves safety during driving.

In this embodiment, the aforementioned filament 2 is one, and correspondingly, the aforementioned first lamp post 3 and second lamp post 4 are also one. The aforementioned filament 2 is vertically arranged, and the two feet of the filament 2 are welded and fixed to the upper ends of the first lamp post 3 and the second lamp post 4, respectively. At this time, the aforementioned first lamp post 3 and the second lamp post 4 are arranged in a state of one short and one long, and the aforementioned filament 2 is located above the first lamp post 3.

[0022] The technical innovation of this utility model is as follows: a horizontally arranged lamp post fixing column 7 is provided inside the lamp body 1. The lamp post fixing column 7 is fixed to the first lamp post 3 and the second lamp post 4 by high-temperature welding. The two ends of the lamp post fixing column 7 extend laterally and contact the inner wall of the lamp body 1. The lamp body 1 is made of quartz glass, and during the molding process, it is formed into a whole with the two ends of the lamp post fixing column 7 by high-temperature welding.

[0023] Furthermore, the upper end of the aforementioned lamp body 1 forms a lamp body cavity 11, and the aforementioned filament 2, first lamp post 3, second lamp post 4, and lamp post fixing post 7 are respectively disposed in the lamp body cavity 11.

[0029] Please continue reading. Figure 1 When halogen lamps are used in vehicles and driven in bumpy environments, the lamp body 1 vibrates with the vibration of the vehicle body. The first lamp post 3 and the second lamp post 4 inevitably vibrate. The lamp post fixing post 7 is not only connected and fixed to the first lamp post 3 and the second lamp post 4, but also connected and fixed to the inner wall of the lamp body 1, that is, the inner side wall of the lamp body cavity 11. Therefore, the first lamp post 3 and the second lamp post 4 form a whole with the lamp body 1 through the lamp post fixing post 7, thereby reducing vibration and reducing the vibration of the filament 2.
