Description

Technical Field

[0001] This utility model relates to the field of automotive halogen bulb technology, specifically to an automotive halogen bulb with a built-in ceramic heat dissipation substrate. Background Technology

[0002] In automotive lighting systems, halogen bulbs have become a common light source for headlights, taillights, and other components due to their advantages such as low cost and moderate brightness.

[0003] In automotive lighting systems, traditional halogen bulbs generate significant heat during operation due to the continuous emission and heating of the filament. Lacking an efficient heat dissipation structure, this heat is difficult to dissipate quickly, leading to excessively high internal bulb temperatures. High temperatures not only accelerate filament oxidation and wear, shortening bulb lifespan, but also pose a risk of the bulb's glass casing cracking due to thermal stress. Therefore, we propose an automotive halogen bulb with a built-in ceramic heat sink substrate. Utility Model Content

[0004] The purpose of this invention is to provide an automotive halogen bulb with a built-in ceramic heat dissipation substrate, in order to solve the problem mentioned in the background art that traditional halogen bulbs lack efficient heat dissipation structures, making it difficult to dissipate heat quickly and resulting in excessively high internal temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car halogen bulb with a built-in ceramic heat dissipation substrate, including a mounting base and a slot. The slot is located at the center of the mounting base. A positioning rail and a slide rail are fixedly installed on both sides of the slot. A rotating gear is slidably connected to the surface of the positioning rail. Ball bearings are arranged around the inner wall of the rotating gear. A roller is rotatably connected to the surface of the ball bearings. A slider is slidably connected to the surface of the slide rail. A snap-fit ​​plate is fixedly installed on the surface of the roller and the slider. A ceramic heat dissipation substrate is snapped onto the surface of the snap-fit ​​plate.

[0006] The card holder has feet fixedly installed on both sides inside, and a lampshade is fixedly installed on the top of the card holder, with a filament fixedly installed inside the lampshade.

[0007] The card holder has a guide rail fixedly installed at the center of its surface, and an adjustment rod is slidably connected to the surface of the guide rail.

[0008] The bottom of the adjusting rod passes through the card holder and is fixedly connected to the surface of the card plate.

[0009] The snap-fit ​​plate is U-shaped, and the ceramic heat dissipation substrate is movably snapped onto the surface of the snap-fit ​​plate. It can be adjusted by rotating gears and sliders on the surface of the slot.

[0010] One side of the filament surface is parallel to and corresponds to the ceramic heat dissipation substrate, and the filament is fixedly connected to the connector.

[0011] A roller is also installed at the center of the slider surface, and the roller drives the snap-fit ​​plate to rotate and adjust on the rotating gear and slider surface through the ball bearings.

[0012] This utility model has at least the following beneficial effects:

[0013] By incorporating a ceramic heat sink inside the bulb, the high thermal conductivity, high insulation, and excellent thermal stability of ceramic materials enable rapid heat dissipation from the filament. The locking plate, along with the rotating gear and sliding adjustment design within the slot, ensures the ceramic heat sink remains parallel and tightly fitted to the filament, maximizing the heat dissipation contact area. This effectively reduces the bulb's internal temperature, extends filament lifespan, and enhances the bulb's overall reliability and stability.

[0014] The combination of rotating gears, ball bearings, rollers, and sliders gives the mounting plate multi-dimensional adjustment capabilities within the slot. Not only can the position of the ceramic heat sink be adjusted by sliding, but the ball bearings can also drive the rollers to rotate the mounting plate, thus flexibly changing the angle and position of the ceramic heat sink according to actual needs, ensuring it is always in optimal heat dissipation condition and improving heat dissipation efficiency. This flexible adjustment method also allows the bulb to adapt to different vehicle models and installation environments, enhancing the product's versatility.

[0015] The U-shaped design of the snap-fit ​​plate, along with the guide rail and adjusting rod, makes the installation and removal of the ceramic heat sink substrate extremely convenient. When the ceramic heat sink substrate is damaged or requires cleaning and maintenance, simply pull the snap-fit ​​plate with the adjusting rod to remove the ceramic heat sink substrate from the slot. This eliminates the need for complex disassembly of the entire bulb, greatly reducing maintenance difficulty, shortening maintenance time, and also lowering operating costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a car halogen bulb with a built-in ceramic heat dissipation substrate, including a mounting base 100 and a slot 200. The slot 200 is located at the center of the mounting base 100. Positioning rails 203 and slide rails 207 are fixedly installed on both sides inside the slot 200. A rotating gear 204 is slidably connected to the surface of the positioning rail 203. Ball bearings 205 are arranged around the inner wall of the rotating gear 204. A roller 206 is rotatably connected to the surface of the ball bearings 205. A slider 20 is slidably connected to the surface of the slide rail 207. 8. A roller 206 is also installed at the center of the surface of the slider 208, and the ball bearing 205 drives the snap-fit ​​plate 201 to rotate and adjust on the surface of the rotating gear 204 and the slider 208. The snap-fit ​​plate 201 is fixedly installed on the surface of the roller 206 and the slider 208. The snap-fit ​​plate 201 is U-shaped. The ceramic heat dissipation substrate 202 is movably snapped onto the surface of the snap-fit ​​plate 201. It is adjusted by sliding on the surface of the slot 200 through the rotating gear 204 and the slider 208. The ceramic heat dissipation substrate 202 is snapped onto the surface of the snap-fit ​​plate 201.

[0025] The card holder 100 has pins 101 fixedly installed on both sides inside. The card holder 100 has a lamp cover 102 fixedly installed on top. The lamp cover 102 has a filament 103 fixedly installed inside. One side of the surface of the filament 103 is parallel and corresponds to the ceramic heat sink 202, and the filament 103 is fixedly connected to the pins 101.

[0026] A guide rail 209 is fixedly installed at the center of the surface of the card holder 100. An adjusting rod 210 is slidably connected to the surface of the guide rail 209. The bottom of the adjusting rod 210 passes through the card holder 100 and is fixedly connected to the surface of the card plate 201.

[0027] Working principle: When the automotive halogen bulb is powered on, pin 101 transmits current to the filament 103 inside the lamp cover 102. The filament 103 heats up and emits light, generating a large amount of heat. At this time, the built-in ceramic heat sink 202 begins to function, utilizing its high thermal conductivity, high insulation, and good thermal stability to quickly conduct the heat generated by the filament 103 to itself.

[0028] During heat dissipation, the snap-fit ​​plate 201 and its related components work together. The snap-fit ​​plate 201 is connected to the adjusting rod 210 at the top. When the adjusting rod 210 slides on the surface of the guide rail 209, the snap-fit ​​plate 201 slides synchronously. The snap-fit ​​plate 201 is connected to the rotating gear 204 and the slide rail 207 via the roller shaft 206 and the slider 208, respectively. Since the rotating gear 204 can slide on the positioning rail 203 and the slider 208 can slide on the slide rail 207, the snap-fit ​​plate 201 can move in different directions within the slot 200, thereby moving the ceramic heat dissipation substrate 202. Simultaneously, the ball bearings 205 around the inner wall of the rotating gear 204 cooperate with the roller shaft 206, allowing the snap-fit ​​plate 201 to rotate and adjust using the ball bearings 205 as a fulcrum. This design allows the ceramic heat dissipation substrate 202 to not only adjust its position but also change its angle. Through this multi-dimensional adjustment, the ceramic heat dissipation substrate 202 can maintain parallel correspondence and close contact with the filament 103, maximizing the heat dissipation contact area and quickly and efficiently dissipating the heat generated by the filament 103 to the external environment of the bulb, thereby reducing the internal temperature of the bulb, ensuring that the filament 103 works at a suitable temperature, and extending its service life.

[0029] When maintenance or replacement of the ceramic heat sink 202 is required, the operation is very simple. The guide rail 209 and adjusting rod 210, located at the center of the surface of the card holder 100, play their role. Simply pull the adjusting rod 210, and it will slide along the guide rail 209, causing the card plate 201, which is fixedly connected to it, to move. Since the card plate 201 is U-shaped, the ceramic heat sink 202 is movably locked onto its surface. As the card plate 201 moves, the ceramic heat sink 202 can be easily removed from the card slot 200 without the need for complicated disassembly of the entire bulb, making the maintenance or replacement of the ceramic heat sink 202 convenient and quick.
