AI Technical Summary
Due to the design defects of the light guide strip structure, the existing through-type taillights have a 60-70cm area that cannot be illuminated when the vehicle is in the whole state, affecting the continuity of the lighting effect. In addition, the large number of LEDs leads to high costs.
The light guide strip is redesigned, combined with a diffuser structure and a uniform light inner cover, to change the light input direction of the light guide strip, so that the heat sink is located in front of or behind the light guide strip. The diffuser structure and the uniform light inner cover weaken the light spot, reduce the area that cannot be lit, and reduce the number of LEDs.
The continuous lighting effect of the through-type taillights is achieved, which reduces costs and improves the lighting uniformity under the whole vehicle state, avoids the formation of obvious light spots, and enhances the aesthetics of the lamps.

Abstract
Description
Technical Field
[0001] The utility model relates to a continuously lit through-type taillight structure. Background Art
[0002] At present, more and more car taillights adopt through-type style. However, in order to make it more consistent with the fixed side lamps after lighting, through-type taillights are basically arranged in a way that a large number of LED particles are evenly distributed, such as Figure 1 As shown, since the length of the through-type taillight is basically greater than or equal to 1.2 meters, in order to ensure uniform lighting, one function needs to be arranged with nearly 100 LEDs, which leads to a significant increase in the cost of the lamp. For this problem, another structure can be used to achieve it, such as Figure 2-5 As shown, the through-type taillights use light guide strips to emit light from both ends, which can greatly reduce the number of LEDs and greatly reduce costs. However, the light input direction of the light guide strips is from both ends toward the middle. Due to the characteristics of the light guide strip structure, there is a relatively obvious bright spot of 20-30cm at the light input end of the LED particles arranged at both ends of the light guide strip, which needs to be blocked with an opaque material. In addition, behind the LED particles, that is, at both ends of the through-type taillights, a 20-30cm radiator space needs to be arranged. Ultimately, there is a 60-70cm area that cannot be lit when the whole vehicle is lit, including the gap between the tailgate and the body, the welding structure of the fixed side lamp, the welding structure of the movable side through-type lamp, the radiator space, and the light guide bright spot blocking structure, which seriously affects the continuity of the lighting effect when the whole vehicle is lit. Utility Model Content
[0003] In view of the above problems, the present invention provides a continuously lit through-type taillight structure, which effectively solves the problems pointed out in the background technology.
[0004] The technical solution adopted in this utility model is:
[0005] A continuously lit through-type taillight structure includes a through-type taillight body, and a light guide strip, an LED module, a heat sink, an inner cover, and a light uniforming inner cover arranged in the through-type taillight body. The light guide strip includes a transverse light guide area, and light entrance guide areas fixed at both ends of the transverse light guide area and bent forward or backward. The LED particles of the LED module face the outer ends of the light entrance guide area. The light uniforming inner cover is arranged on the outer side of the light entrance guide area, and the thickness of the light uniforming inner cover gradually decreases from the ends to the middle of the through-type taillight body. The heat sink is located on the rear side of the LED module.
[0006] Preferably, a light scattering structure is provided at the outer end of the light incident guide area.
[0007] The light emitted by the LED particles is processed through the light-scattering structure to prevent the light emitted by the LED particles from directly leaking out and forming bright spots.
[0008] Preferably, the light-scattering structure includes a light-scattering body fixed on the light-entering guide area and protruding toward both ends of the through-type taillight body. The light-scattering body is fixed with a light-blocking boss on the side facing the LED module and is provided with a light-scattering corrugation on the side away from the LED module.
[0009] The light-scattering structure blocks the light emitted by the LED particles through the light-blocking boss to prevent the light from leaking outward from both ends of the through-type taillight body. At the same time, the light-scattering ripples are used to scatter the light passing through the diffuser to reduce its brightness.
[0010] Through the combined effect of the light-scattering structure and the light-uniform inner cover, the light emitted by the LED particles is effectively weakened, and no obvious light spot is formed on the outer surface of the lamp.
[0011] Preferably, the light diffuser, light-blocking boss, light-entry guide area and transverse light-guiding area are integrally formed.
[0012] One-piece molding makes the structure simpler, reduces production costs, and facilitates assembly.
[0013] Preferably, the inner cover is provided with a pattern for shielding the light-uniform inner cover in the area where the light-uniform inner cover is located.
[0014] Because the pattern is set on the inner cover, when the LED particles are not lit, the uniform light inner cover cannot be seen directly from the outside, making the exterior of the lamp more beautiful. When the LED particles are lit, the light emitted by the LED particles is weakened by the scattered light structure and the uniform light inner cover, and no obvious light spot is formed on the surface of the lamp.
[0015] The utility model weakens the light emitted by the LED particles through the light-scattering structure and the light-uniform inner cover, thereby avoiding the formation of obvious light spots on the surface of the lamp. At the same time, the structure of the light guide bar is redesigned, and the light input direction of the light guide bar is changed, so that the radiator can be installed on the front side or the rear side of the light guide bar. In this way, when the radiator is installed, it will not occupy the space between the two ends of the light guide bar and the through-type taillight body, so that the light-emitting area of the light guide bar is closer to the two ends of the through-type taillight body, thereby reducing the area of the through-type taillight body that cannot be illuminated.
[0016] The utility model changes the thickness of the light-uniform inner cover so that the light emitted by the LED particles can present a gradual effect outside the lamp after being weakened, which is consistent with the lighting effect of the through-type taillight body.

[0033] The present invention will be described in further detail below through specific embodiments with reference to the accompanying drawings.
[0034] like Figure 6-9As shown, a continuously lit through-type taillight structure includes a through-type taillight body 1, and a light guide bar 2, an LED module 3, a heat sink 4, an inner cover 5 and a uniform light inner cover 6 arranged in the through-type taillight body 1. The light guide bar 2 includes a transverse light guide area 21, and a light entrance guide area 22 fixed at both ends of the transverse light guide area 21 and bent forward or backward. The LED particles 31 of the LED module 3 face the outer end of the light entrance guide area 22, so that the light emitted by the LED particles 31 is injected from the outer end of the light guide area 22 and transmitted to the transverse light guide area 21. The uniform light inner cover 6 is arranged on the outside of the light entrance guide area 22, and the thickness of the uniform light inner cover 6 gradually decreases from the end of the through-type taillight body 1 to the middle. The heat sink 4 is located on the rear side of the LED module 3.
[0035] A light scattering structure 7 is provided at the outer end of the light incident guide area 22 .
[0036] The light-scattering structure 7 includes a light-scattering body 71 fixed on the light-incident guide area 22 and protruding toward both ends of the through-type taillight body 1. The light-scattering body 71 is fixed with a light-blocking boss 72 on the side facing the LED module 3 and a light-scattering corrugation 73 on the side away from the LED module 3.
[0037] The light diffuser 71 , the light blocking boss 72 , the light incident guide area 22 and the transverse light guide area 21 are integrally formed.
[0038] The inner cover 5 is provided with a pattern for shielding the light-uniform inner cover 6 in the area where the light-uniform inner cover 6 is located.
[0039] The working principle of this utility model is as follows:
[0040] Due to the gap between the fixed side taillight 11 and the through-type taillight body 1, and due to the design defects of the conventional light guide structure, there is a 60-70 cm non-illuminated area in the lighting effect of the whole vehicle. To solve this problem, the present invention redesigns the structure of the light guide 2, greatly reducing the non-illuminated area, as follows:
[0041] When the LED particles 31 are lit, light enters the light guide bar 2 from the light entrance guide area 22. Due to the change in the direction of the light entrance, the heat sink 4 of the LED module 3 is located on the front side or rear side of the light guide bar 2. Compared with conventional technical solutions, the area that cannot be illuminated due to the lateral space occupied by the heat sink 4 is eliminated. At the same time, the light is weakened by the light-scattering structure 7 and the uniform light inner cover 6 to avoid the generation of light spots. At the same time, the weakened light also matches the luminous effect of the through-type taillight body 1.
[0042] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and is subject to numerous variations. All variations that can be directly derived or conceived by a person of ordinary skill in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
