[0030] This utility model proposes a high-mounted brake light 100.

[0031] Please see Figures 1-3In one embodiment of this utility model, the high-mounted brake light 100 includes a lampshade 1, a lamp housing 2, and a light-emitting mechanism 3. The lampshade 1 has a light-emitting area 11. The lampshade 1 and the lamp housing 2 are detachably connected and form an installation space 21. The light-emitting mechanism 3 is disposed in the installation space 21 and includes a circuit board 31 and a light guide lens 32. Both the circuit board 31 and the light guide lens 32 are mounted on the lamp housing 2, and a light source 311 for emitting light is provided on the side of the circuit board 31 facing the light guide lens 32. The light guide lens 32 faces the light source 311. One side of the circuit board 31 is the first diverging side 321, and the side of the light guide lens 32 facing away from the circuit board 31 is the second diverging side 322. The second diverging side 322 is set towards the light-emitting area 11, and the side of the light-emitting area 11 facing the inner side of the mounting space 21 is the third diverging side 111. The first diverging side 321, the second diverging side 322, and the third diverging side 111 are all provided with diverging patterns. The light emitted from the lamp source 311 is diverged sequentially by the first diverging side 321, the second diverging side 322, and the third diverging side 111 before being emitted from the light-emitting area 11.

[0032] The high-mounted brake light 100 of this utility model features a detachable connection between the lamp cover 1 and the lamp housing 2, facilitating installation and maintenance. This allows for easy replacement or repair in case of malfunctions in the light source 311 or the light guide lens 32, reducing maintenance costs. Furthermore, the light-emitting mechanism 3 is directly mounted on the lamp housing 2, resulting in a compact structure and simple installation. This also reduces the complexity of the internal structure of the high-mounted brake light 100, improving reliability. Specifically, the light emitted from the light source 311 undergoes a first divergence on the first divergence side 321, initially improving the uniformity of light emission. It then undergoes a second divergence on the second divergence side 322, further improving uniformity. Finally, it undergoes a third divergence on the third divergence side 111, further enhancing uniformity, ultimately resulting in uniform light emission from the light-emitting area 11. Compared with the prior art, the high-mounted brake light of this utility model achieves multiple divergence processes by setting divergence patterns on the first divergence side 321 and the second divergence side 322 of the light guide lens 32 and the third divergence side 111 of the lamp cover. This effectively reduces the luminous particle effect, makes the light more uniform and soft, and greatly improves the overall luminous uniformity of the high-mounted brake light 100.

[0033] It should be noted that the light source 311 can be an LED light source from existing technology.

[0034] In one embodiment, the first diverging side 321, the second diverging side 322, and the third diverging side 111 are all covered with diverging patterns. In this embodiment, by covering the first diverging side 321, the second diverging side 322, and the third diverging side 111 of the light-emitting area 11 of the lamp cover 1 with diverging patterns, the light undergoes multiple and omnidirectional divergences during propagation, further reducing the graininess of the light emission and making the light emission more uniform, thus avoiding the phenomenon of excessive brightness or darkness in some areas of the high-mounted brake light. The design of being covered with diverging patterns allows the light to be evenly scattered in multiple directions, forming a softer light effect, while enhancing the three-dimensionality of the light and making the overall visual effect of the vehicle headlight more aesthetically pleasing.

[0035] In one embodiment, the diverging pattern is a striped diverging pattern or a corn kernel-like diverging pattern. Understandably, a striped pattern can guide light to diverge evenly in a specific direction, forming a continuous linear light effect, which is suitable for headlight designs that require strong lines and even light distribution; a corn kernel-like pattern can scatter light evenly in multiple directions, forming a softer light emission effect; therefore, both of the above can make the high-mounted brake light emit light more evenly, reduce the granular appearance of the light emission, and also make the headlight's light emission effect more natural and beautiful.

[0036] Please see Figure 3 and Figure 4 In one embodiment, a plurality of light sources 311 are evenly spaced on the circuit board 31, and the distribution direction of the plurality of light sources 311 is the same as the extension direction of the first diverging side 321; a concentrator 33 is provided between each light source 311 and the light guide lens 32, and the concentrator 33 and the light guide lens 32 are spaced apart, and the light emitted by each light source 311 is focused by the corresponding concentrator 33 and directed toward the first diverging side 321.

[0037] In this embodiment, by setting a concentrator 33, the concentrator 33 can concentrate the light emitted by the lamp source 311 and guide it to the first diverging side 321 of the light guide lens 32, thereby reducing the scattering loss of light and improving the utilization efficiency of light. Through the concentrating effect of the concentrator 33, the light emitted by the lamp source can be gathered and effectively guided into the light guide lens 32, ensuring that the light is emitted uniformly from the light-emitting area 11 and improving the overall brightness of the vehicle lamp.

[0038] It should be noted that the concentrator 33 uses a concentrator from the existing technology.

[0039] In one embodiment, multiple condensers 33 are sequentially connected to form a condensing strip, and one end of the light guide lens 32 along its extension direction is connected to a condenser 33 located nearby via a connecting block 34. The connecting block 34 is mounted on the lamp housing 2 via a stud 35.

[0040] Understandably, multiple concentrators 33 connected together form a single concentrator strip, facilitating quick installation and disassembly of the entire concentrator strip and improving stability. Furthermore, one of the outermost concentrators 33 is connected to the adjacent end of the light guide lens 32 via a connecting block 34, further maintaining relative stability between the concentrator 33 and the light guide lens 32, facilitating stable light transmission and diffusion, and improving reliability. Moreover, by mounting the connecting block 34 onto the lamp housing 2 via studs 35, the concentrator 33 and the light guide lens 32 are fixed to the lamp housing 2, preventing them from shaking during vehicle operation and improving stability.

[0041] Please continue reading. Figure 3 In one embodiment, the lamp housing 2 includes a base plate 22 located at the bottom of the mounting space 21. The base plate 22 is provided with a mounting post 221 extending vertically. A through hole is provided on the connecting block 34 at the position corresponding to the mounting post 221. The mounting post 221 extends into the through hole, and the connecting block 34 is fastened to the mounting post 221 by a stud 35.

[0042] Understandably, by setting mounting posts 221 on the lamp housing 2, which extend into the through holes of the connecting block 34, precise positioning and support are formed, ensuring a more stable connection between the connecting block 34 and the lamp housing 2. The connecting block 34 is then secured to the mounting posts 221 by studs 35, further enhancing the overall stability of the light guide mechanism 3 and preventing the connecting block 34 from loosening or shifting during the operation of the vehicle lamp, thereby further improving the stability of the light guide lens 32 and the concentrator 33.

[0043] Please combine Figure 3 and Figure 4 In one embodiment, a plurality of limiting members 36 are provided at intervals along the extension direction of the top of the focusing strip, and a limiting notch 312 is provided on the top of the circuit board 31 corresponding to the position of each limiting member 36, and each limiting member 36 is engaged with the corresponding limiting notch 312.

[0044] Understandably, by providing multiple limiting members 36 at the top of the focusing strip, the engagement of the limiting members 36 with the limiting notches 312 ensures precise positioning between the focusing strip and the circuit board 31, preventing the focusing strip from shifting or loosening during installation or operation. Furthermore, the cooperation between the limiting members 36 and the limiting notches 312 significantly improves the connection stability between the focusing strip and the circuit board 31, ensuring that the position between the focusing unit 33 and the circuit board 31 is relatively fixed, thereby ensuring the accuracy of the light propagation path.

[0045] In one embodiment, the limiting member 36 includes a snap-fit ​​section 361 and a limiting section 362. The top end of the limiting section 362 and the end of the snap-fit ​​section 361 away from the focusing strip are connected to each other. The snap-fit ​​section 361 snaps into the limiting notch 312, and the limiting section 362 abuts against the side of the circuit board 31 away from the focusing strip.

[0046] In this embodiment, the snap-fit ​​segment 361 snaps into the limiting notch 312, ensuring precise positioning between the focusing strip and the circuit board 31 and preventing the focusing strip from shifting or loosening during installation or operation. The limiting segment 362 abuts against the side of the circuit board 31 away from the focusing strip, further enhancing the connection stability between the focusing strip and the circuit board 31. Through the cooperative design of the snap-fit ​​segment 361 and the limiting segment 362, the connection stability between the focusing strip and the circuit board 31 is significantly improved, ensuring the accuracy of the light propagation path.

[0047] Please see Figure 1 In one embodiment, a rail 12 is provided on the lampshade 1 at the bottom of the light-emitting area 11, and a slot 23 corresponding to the rail 12 is provided on the lamp housing 2. The rail 12 can extend into the slot 23 and engage with the slot 23.

[0048] Understandably, the locking rail 12 extends into and engages with the locking groove 23, significantly improving the connection stability between the lamp cover 1 and the lamp housing 2. This prevents the lamp cover 1 from loosening or shifting relative to the lamp housing 2 during vehicle light operation, ensuring the overall reliability of the vehicle light structure. Furthermore, the engaging design of the locking rail 12 and the locking groove 23 makes the installation of the lamp cover 1 and the lamp housing 2 more convenient, allowing for quick alignment of the lamp cover 1 and the lamp housing 2, reducing adjustment time during installation.

[0049] This utility model also proposes a vehicle that uses the high-mounted brake light 100 as described above. Understandably, the lamp housing 2 of the high-mounted brake light 100 is connected to the vehicle body to achieve lamp assembly. The specific structure of the high-mounted brake light 100 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.
