[0022] Please see Figure 1-6A vehicle lamp according to an embodiment of the present utility model includes a base 100, a light-emitting part and a protective shell 200. The light-emitting part is disposed between the base 100 and the protective shell 200, and a first sealing ring is provided in the gap between the base 100 and the protective shell 200.
[0023] The light-emitting part includes a light-emitting element 400 and a mounting element 300. The light-emitting element 400 is clamped and mounted on the base 100 by the mounting element 300. The mounting element 300 is provided with a plurality of heat dissipation parts.
[0024] In this embodiment, by placing the light-emitting part between the base 100 and the protective shell 200, the light-emitting part can be effectively protected. A first sealing ring is provided in the gap between the base 100 and the protective shell 200 to prevent the light-emitting part from being damaged by short circuits when it gets wet in the rain, thereby improving safety.
[0025] The first sealing ring is a sealing gasket or a silicone ring;
[0026] By providing a heat dissipation part on the mounting part 300, the cost of the light-emitting element 400 is reduced. Moreover, when replacing the more easily damaged light-emitting element 400, there is no need to replace the heat dissipation part as well. At the same time, since the light-emitting element 400 is clamped by the mounting part 300 and the base 100, the mounting part 300 can better absorb the heat on the light-emitting element 400 and dissipate it from the heat dissipation part, resulting in better heat dissipation. In addition, since the light-emitting element is not directly fixed to the mounting part 300, the disassembly and installation of the light-emitting element 400 are simpler.
[0027] The connection between the mounting component 300 and the base 100 can be a detachable connection method such as a snap-fit or screw connection.
[0028] In one embodiment, the protective shell 200 is detachably connected to the base 100 via a snap-fit assembly 500. The protective shell 200 is provided with a first vertical plate 210 and a first horizontal plate 220 on the side facing the base 100. The base 100 is correspondingly provided with a second horizontal plate 110. The second horizontal plate 110 abuts against the first vertical plate 210. The first sealing ring is provided on the side of the second horizontal plate 110 facing the first vertical plate 210.
[0029] In this embodiment, the protective shell 200 and the base 100 are detachably connected by the snap-fit assembly 500, making the protective shell 200, base 100, mounting component 300 and light-emitting component 400 all detachable. Easily damaged parts are easier to replace. At the same time, a large amount of difficult-to-clean dust can easily accumulate on the protective shell 200 and base 100, affecting the overall light-emitting effect. Therefore, they can be disassembled and cleaned when needed to ensure the subsequent light-emitting effect without affecting the light-emitting component 400.
[0030] By setting a first vertical plate 210 and a second horizontal plate 110 along the edge of the protective shell 200, and having them cooperate with the second horizontal plate 110 along the edge of the base 100 and the inner wall of the base 100, a relatively sealed space is formed with four sides surrounding it. A first sealing ring is set at the position where the second horizontal plate 110 abuts against the first vertical plate 210 to achieve a first sealing effect, initially protecting the light-emitting element 400 and preventing the light-emitting element 400 from short-circuiting or being damaged when wading in water.
[0031] This design not only provides a sealing effect through the first sealing ring, but also creates a sealed space that can temporarily block a small amount of water from entering.
[0032] In one embodiment, a sealed space is formed between the second horizontal plate 110, the first vertical plate 210, and the first horizontal plate 220, and a second sealing ring is provided in the sealed space.
[0033] In this embodiment, the second sealing ring can be a multi-layer silicone sealing ring or a waterproof adhesive filler to further enhance the waterproof effect.
[0034] In one embodiment, a third horizontal plate 120 is provided on the inner side of the second horizontal plate 110, and a plurality of guide grooves 130 are provided on the third horizontal plate 120. A plurality of guide blocks are provided on the mounting member 300, and the guide blocks are disposed in the guide grooves 130.
[0035] In this embodiment, by providing the guide groove 130, it can cooperate with the guide block to be positioned when installing the mounting part 300, which facilitates installation;
[0036] Furthermore, a third sealing ring can be installed between the third horizontal plate 120 and the mounting component 300 to further enhance the waterproof effect.
[0037] In one embodiment, the latching assembly 500 includes a latching protrusion 510 and a latching buckle 520, wherein the latching protrusion 510 is disposed on the outer side of the first horizontal plate 220 and the latching buckle 520 is disposed on the outer side of the base 100.
[0038] In this embodiment, the snap-fit assembly 500 is an existing detachable structure. The snap-fit protrusion 510 and snap-fit buckle 520 are both located on the outside, which reduces the connection gap between the base 100 and the protective shell 200, further enhances the waterproof effect, and facilitates disassembly.
[0039] In one embodiment, the mounting member 300 is provided with a plurality of through holes 310, and the light-emitting part of the light-emitting element 400 is installed from one side of the mounting member 300 corresponding to the through holes 310 and extends from the other side of the mounting member 300 by a predetermined length.
[0040] In this embodiment, by providing a through hole 310 on the mounting component 300, the light-emitting part on the light-emitting component 400 can be installed in the through hole 310 for alignment and positioning, which facilitates compliant installation. At the same time, the light-emitting part is installed from one side of the mounting component 300 and extends a preset length from the other side of the mounting component 300, so that the light emission is not blocked and the light emission effect is better. Also, because the extension has a certain distance, it is closer to the protective shell 200, which improves heat dissipation.
[0041] During installation, the light-emitting part of the light-emitting component is aligned with the through hole and embedded in the through hole. Then, the light-emitting component and the mounting component are fixed together on the base to achieve the installation of the light-emitting component and the mounting component.
[0042] Preferably, the installation method in which the light-emitting element and the mounting component are fixed together on the base can be screwed together. That is, screw holes are provided on the mounting component, and through holes are provided on the light-emitting element and the base respectively corresponding to the screw holes. The screw connection is achieved by inserting screws into the through holes of the base and the light-emitting element in sequence on the outside of the base and then screwing them into the screw holes on the mounting component.
[0043] The preset length can be set according to actual needs, preferably 1-2cm.
[0044] In one embodiment, the light-emitting element 400 includes a plurality of surface-mount LEDs 410 and a circuit board. The surface-mount LEDs are soldered onto the circuit board, and the circuit board is in close contact with the mounting member 300. Both the mounting member 300 and the circuit board are made of aluminum-based material with high thermal conductivity.
[0045] In this embodiment, by mounting the circuit board tightly against the mounting component 300, and by using a high thermal conductivity aluminum base material for both the circuit board and the mounting component 300, heat dissipation can be enhanced, light decay can be effectively reduced, and the lifespan of the light source can be extended.
[0046] In one embodiment, the heat dissipation portion is distributed on the mounting member 300 near the protective shell 200, and the heat dissipation portion is disposed near the light-emitting portion on the light-emitting member 400.
[0047] In this embodiment, heat dissipation is further increased by placing the heat dissipation part on the mounting part 300 near the protective shell 200 and near the light-emitting part.
[0048] In one embodiment, the heat dissipation part is a plurality of heat dissipation fins, and the heat dissipation fins are provided with a plurality of extensions extending to the periphery.
[0049] In this embodiment, the heat dissipation efficiency is further increased by configuring the heat dissipation part as a plurality of heat dissipation fins.
[0050] In one embodiment, the heat dissipation fins are provided with a plurality of extensions extending to the periphery, forming a tree-like shape. The extensions located at the bottom (near the connection of the heat dissipation fins) are longer, while the extensions located at the top are shorter. This arrangement is conducive to the rapid dissipation of heat, and at the same time, it will not cause the upper extensions to tilt due to excessive length, thus affecting the heat dissipation efficiency.
[0051] Preferably, the number of heat dissipation fins is at least twice the number of through holes 310.
[0052] In one embodiment, heat dissipation fins are also provided on the circuit board, and heat dissipation through holes are also provided on the mounting component 300 corresponding to the heat dissipation fins.
[0053] An electric vehicle also includes the aforementioned headlights.
[0054] In one optimal embodiment, surface-mount LED chips are precisely soldered onto a specially designed high thermal conductivity aluminum-based circuit board. This aluminum-based circuit board not only has a 30% higher thermal conductivity than conventional materials, but also features heat dissipation fins on the back, forming a three-dimensional heat dissipation structure. This allows the operating temperature of the LED chips to be stably controlled below 75°C, a 5°C reduction compared to traditional designs, effectively reducing light decay and extending the lifespan of the light source.
[0055] The circuit chip incorporates a constant current driver chip with adaptive adjustment (which can be an existing chip). In addition to overvoltage, overcurrent, and short-circuit protection, it automatically adjusts the output current based on fluctuations in the electric vehicle's power supply voltage (within ±10%), ensuring stable LED light source brightness. Furthermore, the driver circuit integrates a wireless control module, allowing remote control of the headlights' on / off state, brightness adjustment, and light mode switching via a mobile app.
[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
