Technical Field
[0001] The utility model relates to the technical field of automobile headlights, in particular to a double-heat-conducting copper tube pointed-end shaped lamp body structure. Background Art
[0002] Automobile lights usually include headlight assembly (front light assembly), fog light assembly and tail light assembly. The headlight assembly can usually emit high beam, low beam, turn signal and daytime running light. With the advancement of technology, the headlight bulbs (high and low beam bulbs) in the headlight assembly have emerged as halogen headlight bulbs, xenon headlight bulbs and the most advanced LED headlight bulbs.
[0003] The current LED headlights include an LED chip for emitting light, a long columnar lamp body for mounting and fixing the LED chip, a heat sink type radiator for heat dissipation, and an air-cooling fan for heat dissipation. However, the current LED chip mainly relies on the radiator to dissipate heat from the end of the LED chip during heat dissipation. Although this achieves the purpose of cooling, the cooling is not obvious, which affects the service life of the LED headlight. Therefore, it is necessary to design a double heat-conducting copper tube pointed lamp body structure. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-3 The utility model provides a double heat-conducting copper tube pointed lamp body structure, including a lamp body 1, a radiator 2 is fixedly connected to the front end of the lamp body 1, an installation cavity 9 is arranged inside the lamp body 1, a circuit board 4 is arranged inside the installation cavity 9, lamp beads 6 are fixedly connected on both sides of the circuit board 4, and heat-conducting copper tubes 5 are fixedly connected at both upper and lower ends of the circuit board 4.
[0023] Specifically, the circuit board 4 is installed inside the lamp body 1, and a cooling fan is installed inside the radiator 2. When the circuit board 4 is working, the cooling fan inside the radiator 2 can cool the circuit board 4. At the same time, two heat-conducting copper tubes 5 are symmetrically installed at the upper and lower ends of the circuit board 4. In this way, the heat dissipation area of the circuit board 4 can be increased, which is conducive to better cooling of the circuit board 4, thereby increasing the service life of the LED headlight.
[0024] The radiator 2 is assembled from a plurality of radiating fins and distributed in a circular array. When working, since the radiator 2 is composed of a plurality of radiating fins, not only the radiating area is increased, but also the gaps between the radiating fins are conducive to the flow of air.
[0025] A positioning hole 7 is provided on the side end face of the circuit board 4, and a positioning column 8 is slidably connected inside the positioning hole 7. The positioning column 8 is fixedly connected to the lamp body 1. During operation, by setting the positioning hole 7 and the positioning column 8, the installation of the circuit board 4 can be limited with the cooperation of the positioning hole 7 and the positioning column 8, thereby effectively preventing the circuit board 4 from separating from the lamp body 1.
[0026] The rear end of the lamp body 1 is pointed, and a buckle 3 is sleeved on the circumferential surface of the lamp body 1. When working, since the rear end of the lamp body 1 is pointed, it is convenient to install the buckle 3, and the lamp body 1 can be conveniently fixed inside the lampshade under the action of the buckle 3.
[0027] A retaining ring 10 is fixedly connected to the circumferential surface of the lamp body 1, and the retaining ring 10 cooperates with the buckle 3. During operation, the retaining ring 10 can be set to limit the installation position of the buckle 3 under the action of the retaining ring 10, effectively preventing the buckle 3 from being over-installed.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
