Description

Technical Field

[0001] This utility model relates to the field of automotive lighting, and in particular to a through-hole LED automotive lamp structure. Background Technology

[0002] Automotive lights are an essential component of automobiles. Currently, the main light sources for automotive lights are halogen lamps, xenon lamps, and LED lamps. Halogen lamps have low efficiency and a lifespan of only about 500 hours; once severe light decay occurs, the light source needs to be replaced promptly. Xenon lamps are more expensive and have a shorter lifespan. LED lamps have significant advantages in luminous efficiency and lifespan, so many manufacturers choose LED lights for their automotive lights.

[0003] However, the light-emitting principle of LED lights dictates that they require timely and good heat dissipation, and heat dissipation is a major factor affecting the lifespan of LED automotive lights.

[0004] Furthermore, as a light source, LED automotive lights need to be combined with other components to form an automotive optical system that meets relevant requirements. Existing products generally separate the lamp body from the power plug, with the lamp body connected to the power plug via wires. This results in numerous components and inconvenient angle adjustments during installation.

[0005] Therefore, it is necessary to improve the existing structure of LED automotive lights. Utility Model Content

[0006] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, one objective of the present invention is to propose a through-hole LED automotive lamp structure that provides sufficient heat dissipation and safe use during operation, while extending the lifespan of the LED automotive lamp.

[0007] The above objective is achieved through the following technical solution:

[0011] In some embodiments, a positioning platform is provided on the outer periphery of the housing, the positioning platform being used to place the positioning part so that the chuck can rotate circumferentially around the housing.

[0012] In some embodiments, a recessed groove is provided above the positioning platform to limit the movement of the retaining ring, thereby limiting the chuck between the positioning platform and the retaining ring.

[0013] In some embodiments, a plurality of heat dissipation strips are provided at the rear end of the housing and under the positioning platform, and a plurality of heat dissipation holes are provided between the rear end of the housing, the card slot and the plug.

[0022] Figure 3 This is a front view of the through-hole LED automotive lamp structure in the embodiment;

[0023] Figure 4 yes Figure 3 Sectional view of part A. Detailed Implementation

[0024] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0025] like Figures 1 to 4 As shown, this embodiment provides a through-hole LED automotive lamp structure, including a housing 1, a plug 2, a driver 3, a heat dissipation module 4, an LED light-emitting component 5, and a snap-fit ​​component 6. The rear end of the housing 1 is cylindrical, the plug 2 is placed at the end of the housing 1 for connecting to a power source, the driver 3 is installed inside the housing 1 near the end of the plug 2, the heat dissipation module 4 is placed inside the housing 1 and electrically connected to the driver 3, and the snap-fit ​​component 6 is on the outside of the housing 1.

[0026] The front end of the outer casing 1 is rectangular. The LED light-emitting component 5 is installed inside the front end of the outer casing 1. Through holes 11 are provided on both opposite sides of the front end of the outer casing 1. The LED light-emitting component 5 includes a heat sink 51, a copper substrate 52, and an LED module 53. The copper substrate 52 is disposed on the heat sink 51, and the LED module 53 is disposed on the copper substrate 52, located within the through holes 11. Light emitted by the LED module 53 is emitted outward through the through holes 11. The heat sink 51 is rectangular, and its area is larger than that of the copper substrate 52. Because the heat sink 51 is rectangular and its area is larger than that of the copper substrate 52, when the lamp body generates heat during operation, the heat on the copper substrate 52 can be transferred to the heat sink 51, thereby dispersing the heat and expanding the effective area of ​​the heat dissipation module 4 for the LED light-emitting component 5, achieving the goal of rapid heat dissipation.

[0027] The through-hole LED automotive lamp structure proposed in this embodiment provides sufficient heat dissipation and safe operation, while also extending the lifespan of the LED automotive lamp.

[0028] Specifically, the snap-fit ​​component 6 includes a chuck 7, which includes a collar 71, a connecting portion 72 extending outward from the collar 71, and a positioning portion 73 extending from the bottom of the collar 71 toward its inner diameter. The connecting portion 72 has several snap-fit ​​portions 721, and the snap-fit ​​component 6 also includes a snap ring 61 disposed on the collar 71. Through the several snap-fit ​​portions 721 on the connecting portion 72, this through-hole LED automotive lamp structure, serving as a light source, can be combined with other vehicle components (such as reflectors) via the snap-fit ​​portions 721 to form an optical system that meets relevant automotive lamp installation requirements.

[0029] Preferably, a positioning platform 12 is provided on the outer periphery of the housing 1. The positioning platform 12 is used to place the positioning part 73 so that the chuck 7 can rotate around the housing 1. Since the plug 2 is fixed to the lamp body, the chuck 7 can rotate around the housing 1, allowing the user to adjust the angle of the LED light-emitting component 5 during installation, thereby allowing the lamp body to fit into the combination installation with other vehicle components.

[0030] Specifically, a recessed groove 13 is provided above the positioning platform 12. The groove 13 is used to limit the movement of the retaining ring 61, thereby limiting the chuck 7 between the positioning platform 12 and the retaining ring 61. The retaining ring 61 not only restricts the range of motion of the chuck 7, but also facilitates disassembly and replacement of the chuck 7 when it is damaged, thus extending the service life of the lamp body.

[0031] Furthermore, several heat dissipation strips 18 are provided at the rear end of the housing 1 and under the positioning platform 12, and several heat dissipation holes 14 are provided between the rear end of the housing 1, the slot 13, and the plug 2. The design of the heat dissipation strips 18 and the heat dissipation holes 14 ensures sufficient ventilation for the lamp body, providing comprehensive heat dissipation.

[0032] Furthermore, the heat dissipation module 4 includes a drive motor 41 and a cooling fan 42 electrically connected together. The drive motor 41 and the cooling fan 42 work together to generate airflow that blows towards the LED light-emitting component 5, especially the heat sink 51. Because the heat sink 51 has a large area, the contact area with the airflow is increased, thereby improving the heat dissipation efficiency of the heat dissipation module 4 for the LED light-emitting component 5.

[0033] Preferably, the plug 2 is fixedly connected to the housing 1 to form a straight-plug design, making the plug 2 and the lamp body an integral part, thereby reducing the number of parts and making it easier to adjust the angle during installation.

[0034] Preferably, the heat sink 51 is made of copper. It has better thermal conductivity and can transfer the heat generated by the LED module 53 more quickly.

[0035] Furthermore, the housing 1 includes a first aluminum lamp body 16 and a second aluminum lamp body 15, which are detachably connected together by screws 17. This facilitates assembly, makes it easy to replace damaged parts, and extends the lifespan of the LED automotive lamp.

[0036] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
