Description

Technical Field

[0001] This utility model is a halogen bulb-shaped LED bulb. Background Technology

[0002] In automotive lighting systems, signal lights (such as turn signals, brake lights, and position lights) play a crucial role in driving safety. In recent years, with the development of LED (light-emitting diode) technology, LED signal lights have gradually replaced traditional halogen bulbs and become the mainstream choice. Compared with traditional halogen bulbs, LED signal lights have many advantages such as lower energy consumption, longer lifespan, and faster response speed, and are therefore widely used in modern automotive lighting systems.

[0003] However, existing conventional LED signal lights still have certain limitations in application. First, the strong directional nature of LED light emission results in a relatively small coverage area, which may lead to uneven lighting and affect the visibility and warning effect of the signal lights. Second, because the light emission position of LED signal lights differs from that of traditional halogen bulbs, they often cannot perfectly match the reflectors of the original vehicle bulbs when replacing them, thus affecting the final light pattern and preventing the lighting range and brightness distribution from reaching their optimal state. Utility model content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a halogen bulb-shaped LED bulb.

[0005] A halogen bulb-shaped LED bulb includes a lampshade, a lamp holder, and a light-emitting component. The lampshade and lamp holder are shaped like a W5W halogen bulb. The lamp holder is a solid structure with a boss on its upper surface. The upper surface of the boss has two through holes, and each of the two through holes has a pin inside. The lampshade is a shell structure with its inner side connected to the outer side of the boss. The light-emitting component is located inside the lampshade and connected to the pin.

[0006] Furthermore, the connection between the lampshade and the lamp holder is coated with sealant.

[0007] Furthermore, a current-limiting resistor is provided on the pin.

[0008] Furthermore, the lampshade is made of a transparent material.

[0009] Furthermore, the lower section of the outer side of the boss has an annular recessed structure, which forms a first annular groove with the upper surface of the lamp holder. The inner side of the lampshade is provided with a second annular groove above its bottom surface, and the lampshade is mortised and tenoned with the boss.

[0010] Furthermore, the light-emitting component includes a filament support and a diode. The filament support has a U-shaped structure, with each end connected to a pin. The diode is mounted on the filament support and suspended inside the lamp cover.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0012] Adopting a contoured design similar to the W5W halogen bulb, it can directly replace traditional halogen bulbs, is compatible with existing lamp holders, requires no additional modifications, and expands its application range.

[0013] The lamp holder has a solid structure, which enhances the overall strength, reduces damage caused by vibration or external force, and improves durability.

[0014] The lamp holder has a boss and a through hole on its upper surface for fixing the pins, making the electrical connection more stable and ensuring the long-term reliable operation of the LED bulb.

[0015] The connection between the lampshade and the lamp holder is coated with sealant, which improves the dustproof and waterproof performance, making it suitable for humid or dusty environments and extending its service life.

[0016] Setting a current-limiting resistor on the pin effectively controls the LED's operating current, prevents overload damage, and improves the LED's stability and lifespan.

[0017] The lampshade is made of transparent material, which increases light transmittance, reduces light loss, and enables the LED light source to emit light more efficiently, thereby improving the lighting effect.

[0018] The annular recessed structure on the boss cooperates with the annular groove of the lampshade to achieve a mortise and tenon connection, which enhances the bonding strength between the lampshade and the lamp holder, improves the shock resistance, and simplifies the assembly process.

[0019] The light-emitting component adopts a U-shaped filament support structure and suspends the diodes inside the lamp cover, making the distribution of LED light source more uniform, while optimizing heat dissipation and improving service life.

[0020] Compared to traditional halogen bulbs, LED light sources have higher energy efficiency, which can effectively reduce energy consumption, reduce heat generation, and improve overall luminous efficacy and energy saving.

[0021] The modular design simplifies assembly, reduces production difficulty, and facilitates maintenance and replacement, thus improving market adaptability. Attached Figure Description

[0026] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0027] A halogen bulb-shaped LED bulb includes a lampshade 1, a lamp holder 2, and a light-emitting component. The lampshade 1 and the lamp holder 2 are shaped like a W5W halogen bulb. The lamp holder 2 is a solid structure with a boss on its upper surface. The upper surface of the boss has two through holes, and each of the two through holes has a pin 5 inside. The lampshade 1 is a shell structure, and its inner side is connected to the outer side of the boss. The light-emitting component is located inside the lampshade 1 and is connected to the pin 5.

[0028] The LED bulb in this embodiment adopts a contour-following design, making its shape similar to a W5W halogen bulb to ensure compatibility. The solid structure of the lamp holder 2 provides stable support, and the boss structure is used to fix the pin 5, enabling it to be reliably connected to the light-emitting component. The lamp cover 1 adopts a shell design to protect the light-emitting component and ensure light transmission. After the light-emitting component is connected to the pin 5, the LED is lit by power supply to realize the lighting function.

[0029] This LED bulb offers excellent shape-mimicking performance and can directly replace a W5W halogen bulb, improving its compatibility. The solid bulb holder (2) increases the bulb's structural strength and enhances its durability. The boss structure secures the pin (5), ensuring stable electrical connections. The overall structure is simple, easy to assemble, and improves production efficiency.

[0030] In other embodiments, the shape of the lampshade 1 can be adjusted to accommodate halogen bulbs of different sizes to fit more types of lamp holders 2. Furthermore, the lamp holder 2 can be made of metal or high-temperature resistant plastic to improve heat resistance and lifespan.

[0031] The application of sealant can enhance the bonding force between the lampshade 1 and the lamp holder 2, prevent dust and moisture from entering the bulb, thereby protecting the light-emitting components and improving the protection level of the bulb.

[0032] After applying sealant, LED bulbs have better dustproof and waterproof performance, making them suitable for outdoor or humid environments, extending bulb lifespan, and reducing maintenance costs.

[0033] A current-limiting resistor is located on pin 5. This resistor controls the LED's operating current, preventing excessive current from damaging the LED, thus stabilizing its luminous performance and extending its lifespan. The current-limiting resistor effectively protects the LED from overload and burnout, while also optimizing brightness and improving energy efficiency.

[0034] In one possible implementation, the lampshade 1 is made of a transparent material. The transparent material of the lampshade 1 ensures efficient light transmission, allowing the LED light to diffuse fully and improving the lighting effect. Using a transparent lampshade 1 can improve light output efficiency, reduce light decay, increase brightness, and, depending on requirements, allow for the selection of glass or high-transmittance plastic to improve the bulb's impact resistance.

[0035] In one possible implementation, the lower section of the outer side of the boss has an annular recessed structure, which forms a first annular groove 6 with the upper surface of the lamp holder 2. The inner side of the lampshade 1, above its bottom surface, has a second annular groove 7. The lampshade 1 is mortised and tenoned with the boss. This mortise and tenon joint makes the connection between the lampshade 1 and the lamp holder 2 tighter, increases mechanical strength, improves assembly accuracy, reduces reliance on sealant, and enhances structural stability. The mortise and tenon connection increases the structural strength of the bulb, improves vibration resistance, reduces production costs, and makes assembly more convenient.

[0036] In one possible implementation, the light-emitting component includes a filament support 4 and a diode 3. The filament support 4 has a U-shaped structure, with each end connected to a pin 5. The diode 3 is mounted on the filament support 4 and suspended inside the lamp cover 1. The U-shaped filament support 4 supports the diode 3 and provides electrical connection, enabling the diode 3 to emit light stably. Its suspended arrangement inside the lamp cover 1 optimizes the illumination angle. The U-shaped filament support 4 improves the stability of the diode 3, optimizes heat dissipation, and achieves uniform light distribution.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
